RAINBOW ON TAPE
For No-Fuss Fun

Back issues of rainbow on tape
are available beginning with the
April 1982 issue. A single copy of
rainbow on tape is $10 within the
United States; U.S. $12 in all other
countries. The annual subscription
rate for rainbow on tape is $80
within the U.S.; U.S. $90 in Canada;
and U.S. $105 for all other coun-
tries.*

RAINBOW ON DISK
Offers OS-9 Programs

In addition to all the programs
offered on tape, part of one side of
rainbow on disk is formatted for the
OS-9 operating system. That means
you can now get all the OS-9 pro-
grams from the magazine — pro-
grams that cannot be put on tape.
Back issues of rainbow on disk are
available beginning with October
1986. Subscriptions to rainbow on
disk are $99 a year in the U.S. Cana-
dian rate is U.S. $115. All other
countries, U.S. $130. Single copy
rate is $12 in the U.S.; U.S. $14 in
Canada; and U.S. $16 in all other
countries.*

Please note: While group purchases of RAINBOW ON TAPE and RAINBOW ON DISK are permitted (and multiple subscriptions are even discounted, if purchased in one
order from a club), no license to make copies is conveyed or implied. Yes, your group may even purchase a subscription to our disk/tape services, but such purchase
in no way authorizes that any copies be made of that original disk/tape. Specifically, this means that the original disk/tape itself may indeed be kept in a club library
for use by members. However, a group purchase does not entitle club members, individually or as a group, to copy that disk/tape.
Unauthorized copying of any copyright product is strictly illegal. The copyright (right to make copies) is in no way conveyed in the purchase transaction.

Double-sided DeskMate 3

Editor:

As an owner of a double-sided disk
system I realized that using DeskMate J,
with two disks configured for a 35-track
single-sided system, was a waste of power.
So I put everything in one double-sided
disk. I just wanted to let you know that the
package is now much more enjoyable to
use.

Here's what I did. First, format a blank
disk as double-sided 40-tracks, using a
customized OS-9 Level II system disk.
Then, make a boot file on the blank disk
using the configuration utility included with
the Level II package containing the follow-
ing options: p; t2;d0 -40dordl-40d;ddd0-
40d; term-vdg; no windows unselect the w
and wl that come selected within the util-
ity); and 60 HZ (American Power) for the
clock module. After the boot file is gener-
ated, select the "No commands, stop now"
option and your work with Conf i g will be
finished. Now you have a bootable double-
sided disk ready to receive the files from
both DeskMate 3 disks.

Here is how to d s a v e the files contained
in the DeskMate 3 disks using pipes, so if
your customized OS-9 Level II system disk
doesn't handle pipes, prepare a new one
that can do this, keeping in mind that pipes
are useful when dealing with dsaves.

With the OS-9 disk in Drive 0, load
dsave, copy and makedi p. Insert DeskMate
3's Disk 1 in Drive 0 and the newly
formatted disk in Drive 1, type chd/do
then, press enter, dsave /dO /dl I shell,
and press enter and wait until the proce-
dure is over. Then insert Disk 2 of Desk-
Mate 3 in Drive 0 and type chd/do/cmds
and press enter, dsave /dO /dl/cmds i
shel 1 and press enter. Don't bother with
the Error #218 message that will appear
during this last saving procedure, they are
"file already exists" errors and will denote
only that there are some identical files in
both disks of DeskMate 5.

When the job above is done, boot this
new version of DeskMate 3 and config it as
you want remembering only that both the
folders three and four must refer to directory
/dO/cmds. After configuring your Desk-
Mate 3 to match your hardware, don't for-
get to put a write protect tab on the disk.
And finally, just reboot your customized
DeskMate 3 and start playing with it. Note

that you will be able to format and backup
40-track double-sided disks from within
this new DeskMate 5.

For those with only one disk drive, change
the dsave commands accordingly and swap
the disk when prompted.

Click'n Blink

Editor:

I want to contribute a small improve-
ment to Mr. Dingle's excellent CoCo Pong
program (January '89, Page 63). Consider-
able improvement is achieved by the fol-
lowing:

Change Line:

140 PC0PY1 TO 2:PC0PY1 TO 3

Add line:

155 PMODE 0,2

Change lines:

300 PSET (X.Y.l) : PC0PY2 TO 1

310 IF PP0INT(X+MX,Y)=5 THEN MX
=-MX:EXEC43345

320 IF PP0INT(X,Y+MY)=5 THEN MY
=-MY:EXEC43345

Add Line:

361 PC0PY2 TO 1

Change Line:

380 PC0PY2 TO 3 : SOUND100 , 5 : SOUND
1,4:X=140:Y=RND(131 )+19:MS=-MX
:MY=-MY : RETURN

These line changes and additions re-
move the blinking of the paddles and ball
and add a small "click" when the ball is hit
(EXEC43345 is a ROM call that does this)
without appreciable loss of speed.

INFORMATION PLEASE

Editor:

I am using the genealogy program An-
cestors, by Christopher Meek, to catalog
relatives of the past. Unfortunately, the
program has several draw backs, which
Chris says he doesn't have the time to
devote writing patches for. Since numer-
ous people have written modifications or

Telwriter-64, 1 was wondering if the same
has been done for Ancestors.

If anyone is familiar with adapting An-
cestors please write to me.

The Unknown Pirate

Editor:

Help! I'm a new CoCo user and was
trying to make a copy of DeskMate that I
purchased for my CoCo 2, and I turned off
the CoCo before I took the disk out of the
drive. No more program. Can anyone send
me a copy? I'd be glad to compensate for
someone's time and disk.

Y. Jones

Sorry, but if someone were to send you
a copied disk they would be guilty of pirat-
ing software. Your best bet is to contact
your local Radio Shack dealer for a re-
placement.

Looking for an Ink Well

Editor:

I am the owner of the Mac Inker from
Computer Friends in Portland, Oregon, one
of your former advertisers. They are appar-
ently no longer in business because my
letter to them was returned marked "unde-
liverable". Since I need some more printer
ribbon ink, is there anyone who knows
where I can buy black ink for printer rib-
bons?

Most office supply stores should stock
ink for re -inking ribbons.

Editing the Point

Editor:

Can you help me? I am looking for an
OS-9 Level II pointers editor (e.g., instead
of an hourglass, a cloud with a couple of Z's
in it).

REQUEST HOTLINE

Editor:

I'd like to write a few words to you about
a problem the whole European CoCo
community faces.

Month after month we avidly read the
rainbow. Of course, we also read The Da-
tabase Report, and that' s where our frustra-
tions begin. We constantly read of interest-
ing programs uploaded on Delphi, while
knowing the programs are unavailable to
us. The costs to go on-line on a BBS in the
States from Europe are forbidding.

According to the latest telephone direc-
tory for Belgium, a conversation with the
U.S., not involving an operator, costs more
than $2 a minute. If the telephone link is
made by an operator, it is almost $2.40 per
minute.

Furthermore, in Belgium and many other
European countries, not many people have
a modem. And moreover, there are only a
few BBSs here, most uninteresting.

We fully understand that Delphi is a
commercial company with protected inter-
ests. We do not expect free programs. But
there must be a solution. Couldn't someone
at Delphi put these programs on disk to be

sold to CoCo users outside the U.S.? It
certainly is not going to take away partici-
pants from the BBS since buyers would be
primarily those unable to log on or who
have no modem.

It may also discourage software piracy,
a problem that has resulted from a complete
lack of support for the CoCo market here.

Ludo LeJeune
Belgium

Good idea! We'll discuss your sugges-
tion with Delphi and keep you posted on
the results.

KUDOS

Editor:

I am a CoCo 3 owner as well as sub-
scriber to this remarkable publication.
Through the past year I have closely moni-
tored the product reviews and after the
January 1989 review of Max-10, I called
and ordered CoCo Max III and Max- 10.
The person I spoke with was polite and
extremely professional, answering all my
questions promptly and indicating that I
would receive my software within 1 0 days.

I anxiously awaited my order as this
was my first purchase through the mail; six

days later, during the Christmas season, I
received my programs and am absolutely
thrilled. My CoCo 3 has come to life,
creating graphics and text effectively and
efficiently.

Thank you rainbow and Colorware.

Living up to Promises

Editor:

Zebra Systems has one of the fastest
delivery systems I have seen. I mailed a
check for CoCo Graphics Designer Plus
on February third, and received it on the
10th. It took only seven days while a friend's
order with another company, by credit card,
took 14 days.

The product not only arrived quickly,
but lived up to its promises. It is much
better than the older basic version. I found
it easy to use and very powerful.

It is nice to see that most companies
have great service. I have ordered products
from several other companies, but none
had the speed that Zebra Systems showed.

Some Help from my Friends

Editor:

Recently, I took a computer test for a
Jets Team competition. This was through
my Physics class. There were tests that
pertained to all areas of study (Physics,
Math, English, etc.). I placed third overall
of about 30 students from many different
schools around the area.

The test consisted of many flow charts,
converting numbers to decimal, binary,
hexadecimal and questions about comput-
ers in general. There were also a lot of
questions dealing with many languages
(Pascal, Assembly Language and FOR-
TRAN).

I'm just writing to say that I couldn't
have done that well without the articles I
read from Dale Puckett and William Barden,
Jr. They explained many technical things in
an easy-to-read format. So, thanks and keep
up the good work.

Out of Rough Water

Editor:

I want to thank Mr. Puckett and others at
rainbow for your assistance in getting this
old retired sailor out of rough water with
Multi-Vue. After reading his instructions I
had no trouble changing my boot. Now I
enjoy using that program.

I like using Computerware's word
processor Screen Star, and would like to
know if anyone has changed the screen
driver so it will work with Multi-Vue?
When I try going from OS -9 to Screen Star
without rebooting I get the message that
Screen Star takes a special driver. I would
like to use it on an 80-column screen.

REVIEWING REVIEWS

Editor:

I am extremely dissatisfied with the
program CoCo Newsroom. When I read the
product review in your magazine, I was led
to believe that this was a quality program.
I find this is not the case.

The Type-up subroutine does not allow
for return to the main menu. There is no
way that I could find to move to the Lay-
Out program after preparing the text. This
is not to mention the clumsy process for
setting up the text. There is no wrap-around
feature at all. If the word typed is too long
for the line, it divides haphazardly between
two lines of text.

The Newspaper Picture Disk would not
load. I suspect this was because it has no
graphics programs on it to load. I wonder
what else is missing from this program.

All in all, this was a frustrating experi-
ence. Paying good money for shoddy mer-
chandise gives all software companies a
bad name. I suppose it might be silly to
expect a refund, but I am going to ask for it
anyway.

CoCo Newsroom, which was previously
sold by Spectrum Projects and Microcom
Software, is no longer on the market. Eric
Wolf, the author of the program, has re-
vised the program and has given Second
City Software exclusive rights to sell the
new version, now called Newspaper Plus.

Second City Software is offering owners
of CoCo Newsroom to upgrade to the new
Newspaper Plus system for $ J 9.95. Simply
send your original disks and manual, along
with $19.95 to Second City Software and
your original copy will be replaced with
Newspaper Plus.

Plus, see "Desktop Publishing Comes to

Another View

Editor:

I take mild exception to the review of
Max- 10 by Jim K. Issel in the January '89
issue of the rainbow. His unreserved en-
thusiasm for the program is understand-
able. It is a remarkable program for those
who want a graphics-based word-proces-
sor or desktop publisher. However, I think
a word of caution is in order: this is not a
word processor for the beginner or, for
anybody's only word processing program.
One reason is that as a graphics-based
program, its printed output is painfully
slow for text-only applications. For those
who want to mix pictures with text or use a
variety of fonts, that is a perfectly accept-
able trade-off. But for those who will be
using a word processor mostly for straight
text, to type letters, memos, reports, etc., a
character-based word processor like
Telewriter- 128 would be easier to use and
would be much faster in producing a printed
copy. Also, for typing a straight-text docu-
ment, I find the mixture of keyboard and
joystick operations required by Max-10 to
be unnatural and awkward compared to the
keyboard-only operation of a character-
based word processor.

So, to alter Jim Issel's bottom-line
comment, if you want to mix pictures with
text, experiment with fancy fonts or un-
usual layouts, this is a marvelous program
that's a lot of fun to use — buy it, you'll like
it! But if you want a work-horse word
processor primarily for typing text, buy
something else, you'll be glad you did.

Copy Protection a Nuisance

Editor:

I purchased a CoCo 3 and must applaud
MicroWorld for their good service. The
one thing that I don't like about the new
machine is its incompatibility with some of
the best software, such as CoCo Max II. It
seems that some programmer could come
up with a way to fully emulate a CoCo 2 on
the new machine. Part of this incompatibil-
ity can be overcome by disabling all CoCo
3 commands with POKE 65502.0 (POKE
65503.0 to re-enable) and some others by
running ROM RAM as published in previous
editions of the rainbow. I have found that
CoCo Graphics Designer requires ROM RAM,
while Don t Forget! will run correctly after
the poke. If anyone can find a simple method
to run CoCo Max 11 please let me know,

I have recently ordered Max-10, and like
the features. What appalls me is the copy
protection scheme, which will be a major
nuisance when using a Hi-Res Joystick
Interface. The ad, which states "disk not
copy protected", is misleading, as it sug-
gests that no protection is used. This hard-
ware protection scheme would have been
unknown to me if not for your thorough
review in January. I have seen such devices
for PCs, but had hoped not to see such for
the CoCo.

Review for Word Power

Unparalleled Power packed in this 100% ML Word Processor
written from scratch for the CoCo 3! No other word processor
offers such a wide array of features that are easy to learn & use.

Word Power 3.2 runs at double-clock speed
and uses the true 80-column display with
lowercase instead of the graphics screen. The
result is lightning fast screen reformatting and
added speed! All prompts are displayed in
plain English in neat colored windows. The current column num-
ber, line number, page number, percentage of free memory is dis-
played at all times. Even the page break is displayed so you know
where one page ends and the other begins. The Setup program
allows you to change fore/background colors as well as (in)visible
carriage returns. Word Power 3.2 can be used with RGB/Com-
posite/Monochrome monitors as well as TV.

Balancing

a RAINBOW

One of the most difficult things
about publishing THE RAINBOW
has always been the job of
booking the magazine every month.
Booking, you see, is the process by
which we select the stories and articles
that will appear in its pages.

Managing Editor Jutta Kapf-
hammer, Submissions Editor Tony
Olive and a number of others all con-
tribute to this process. They do a signif-
icant job, based on a few guidelines set
up by me. Those guidelines are simply
that we must have a broad range of
ideas, topics and things you can do with
your CoCo in each issue.

One thing that amazes me, as we
approach our Eighth Anniversary Issue
and begin our ninth year of publication,
is how well our staff handles this proce-
dure. Another is that the more things
change, the more they stay the same.

What I mean is that almost since
rainbow's inception, we have received
letters and calls asking us for "more" of
this or "less" of that. Frequently on the
very same day, I get letters stating
readers' opinions that we have "too
many games and not enough serious
stuff" and that we have "too much
technical material and not enough
games or fun projects." The same goes
for "too many little simple things" and
"not enough short, simple programs."

I have always taken the position that
as long as both sides complain, both
sides are getting what they want. Re-
member, THE rainbow reaches a wide

audience of paid circulation — some
65,000 in all. (By the way, that is not
"readership," because we have never
used that sort of figure. Some maga-
zines do, figuring something like 7.3
people read each issue and quoting that
number. We never do.)

One of the reasons for this is because
the shape of the CoCo Community is
ever-changing. And it changes within
the scope of a year as well. It is no secret
that more CoCo sales are made in the
November-January period than any
other and these users are new to our
world. We try to hand-hold a little more
in the earlier part of the year than at
other times; it is one of the reasons our
"Beginner's Issue" comes out in January
of each year.

Still, except for the occasional lost or
torn-up magazine — usually the fault of
the postal systems we use (United States
and Canadian, plus a lot of other coun-
tries to a lesser extent) — the "content"
issue is the one we hear the most about.

There are several reasons for it, and
one of them is simply that of scale. Take
the 160-plus pages in this month's issue
and devote 20 of them to games, and
you end up with readers deep into OS-
9 who are unhappy that 20 pages are
"wasted" on games. Yet that represents
but 13 percent of the total available
pages. Of course 20 pages is about half
the total available if we were, say, a little
50-page magazine.

At one time we considered splitting
THE RAINBOW up into two parts — a

"serious" magazine and a "fun" maga-
zine. However, after discussions with a
lot of people, some surveys of readers
and some hard thinking, we decided this
would be neither practical nor useful to
the CoCo Community as a whole.

Yes, we would probably have
stemmed some of the complaints, but
our research showed we would have
forced easily a third of you to buy two
magazines. We would have also ended
up pressuring our advertisers to adver-
tise in two places.

Both of those would have been silly
for us to do — and destructive to the
CoCo Community.

That is why our booking process is so
important. We make sure we have a
balance because that is what we want
and what our research says the vast
majority of you prefer. If you are a game
fanatic, we've got a bunch of pages of
material for you; if you are heavily into
OS-9, we have a bunch of pages for you,
too. And we will continue to do so.

All we ask is simply to look at what
you get, not what someone else gets,
too. By appealing to the entire CoCo
Community as we do, we can afford to
produce a top-quality magazine for you
every month, hold onto columnists you

like, and provide a way for you to learn
all the excellent new products available
to you by our advertisers.

'We make sure we have
a balance because that

is what we want and
what our research says

the vast majority of
you prefer. "

THE RAINBOW is an inexpensive pur-
chase both for you and for our adver-
tisers. Assume we deliver 165 pages a
month for 12 months: That costs you
just a a little more than a penny a page.
If, say, we delivered 50 pages every
other month, the magazine would cost
you five cents a page even if we cut our
subscription rate in half.

As far as advertisers are concerned,
a comment made by Terry Simons of
Des Moines, Iowa, in his CoCo club
newsletter is a good case in point. He
quotes information and rates from THE

rainbow and from a newsletter with a
claimed circulation of about 1,000. If we
use Terry's figures, it costs about $30 to
reach 1,000 people through THE RAIN-
BOW, while the cost for reaching the
same 1,000 people in the newsletter he
mentioned would be $180.

That is pretty much off the subject.
I was saying that we at THE RAINBOW
work hard to give you a balanced
magazine that is useful to everyone. I
think our editors do a fine job, and 1
know most of you agree. For those who
sometimes get frustrated, consider the
scale of what you hold in your hands
right now. It is an important consider-
ation.

Meanwhile, here in Kentucky, the
flowers are beginning to bloom and we
are making plans for the Eighth Anni-
versary Issue. It is what we call "Derby
season," because the Kentucky Derby is
right around the corner.

Derby is exciting and so is spring. But
here, there is nothing quite as exciting
as planning another Anniversary Issue
and looking forward to serving all of
you and the CoCo Community in the
years ahead.

How To Read Rainbow

When we use the term CoCo, we refer to an affection-
ate name that was first given to the Tandy Color
Computer by its many fans, users and owners.

The basic program listings printed in the rain-
bow are formatted for a 32-character screen — so they
show up just as they do on your CoCo screen. One easy
way to check on the accuracy of your typing is to com-
pare what character "goes under" what. If the charac-
ters match — and your line endings come out the same
— you have a pretty good way of knowing that your
typing is accurate.

We also have "key boxes" to show you the minimum
system a program needs. But, ofo read the text before
you start typing.

Finally, the little disk and/or cassette symbols on the
table of contents and at the beginning of articles
indicate that the program is available through our
RAiNBOWONDiSKor rainbow on TAPEservice.

Using Machine Language

The easiest way to "put" a machine language program
into memory is to use an editor/assembler, a program
you can purchase from a number of sources. All you
have to do, essentially, is copy the relevant instructions
from the rainbow's listing into CoCo.

Another method of putting an ML listing into CoCo
is called "hand assembly" — assembly by hand, which
sometimes causes problems with ORlGiNor EQUATE
statements. You ought to know something about
assembly to try this.

Use the following program if you want to hand-
assembie ML listings:

10 CLEAR200,&H3F00:I=&H3F80

20 PRINT "ADDRESS: ";HEX$( I);

30 INPUT "BYTE";B$

40 POKE I, VAL("&H"+B$)

50 I = I+l:GDTO 20

This program assumes you have a 16K CoCo. If you
have 32K, change the &H3F00 in Line 10 to &H7F00
and change the value of I to &H7FB0.

OS-9 and RAINBOW ON DISK

The OS-9 side of rainbow on disk contains two
directories: CMDS and SOURCE. It also contains a file,
read . me . f i rst, which explains the division of the
two directories. The CMDS directory contains executa-
ble programs and the SOURCE directory contains the
ASCII source code for these programs. BASIC09
programs will only be offered in source form so they will
only be found in the SOURCE directory.

OS-9 is a very powerful operating system. Because
of this, it is not easy to learn at first. However, while we
can give specific instructions for using the OS-9

programs, you will find that the OS-9 programs will be
of little use unless you are familiar with the operating
system. For this reason, if you haven't "learned" OS-9
or are not comfortable with it, we suggest you read The
Complete Rainbow Guide to OS-9 by Dale Puckett and
Peter Dibble.

The following is not intended as a course in OS-9. It
merely states how to get the OS-9 programs from
rainbow on disk to your OS-9 system disk. Use
the procedures appropriate for your system. Before
doing so, however, boot the OS-9 operating system
according to the documentation from Radio Shack.

1) Type load dir list copy and press enter.

2) If you have only one disk drive, remove the OS-9
system disk from Drive 0 and replace it with the OS-
9 side of rainbow on disk. Then type chd/d0
and press enter. If you have two disk drives, leave
the sytem master in Drive 0 and put the rainbow
ON disk in Drive 1. Then type chd/dl and press

ENTER.

3) List the read . me . f i rs t file to the screen by typing

list read. me. first and pressing ENTER.

4) Entering dir will give you a directory of the OS-9
side of rainbow on disk. To see what programs
are in the CMDS directory, enter dir cmds. Follow
a similar method to see what source files are in the
source directory.

5) When you find a program you want to use, copy it
to the CMDS directory on your system disk with one
of the following commands:

One-drive system: copy /d0/cmds/ filename /d0/
cmds /filename -s

The system will prompt you to alternately place the
source disk (rainbow on disk) or the destination
disk (system disk) in Drive 0.
Two-drive system: copy /dl/cmds/ filename 'dQ/
cmds/ filename

Once you have copied the program, you execute it
from your system master by placing that disk in Drive
0 and entering the name of the file.

CERTIFICATION
SEAL

The Rainbow Certification Seai is our way of helping
you, the consumer. The purpose of the Seal is to certify
to you that any product that carries the Seal has actually
been seen by us, that it does, indeed, exist and that we
have a sample copy here at the rainbow.

Manufacturers of products — hardware, software and
firmware — are encouraged by us to submit their prod-
ucts to the rainbow for certification.

The Seal is not a "guarantee of satisfaction." The
certification process is different from the review
process. You are encouraged to read our reviews to
determine whether the product is right for your needs.

There is absolutely no relationship between advertis-
ing in the rainbow and the certification process.
Certification is open and available to any product per-

taining to CoCo. A Seal will be awarded to any com-
mercial product, regardless of whether the firm adver-
tises or not.

We will appreciate knowing of instances of violation
of Seal use.

Rainbow Check Plus

The small box accompanying a program listing in
the rainbow is a "check sum" system, which is
designed to help you type in programs accurately.

Rainbow Check PLUS counts the number and values
of characters you type in. You can then compare the
number you get to those printed in the rainbow.
On longer programs, some benchmark lines are given.
When you reach the end of one of those lines with your
typing, simply check to see if the numbers match.

To use Rainbow Check PLUS, type in the program
and save it for later use, then type in the command run
and press enter. Once the program has run, type nen
and press enter to remove it from the area where the
program you're typing in will go.

Now, while keying in a listing from the rainbow,
whenever you press the down arrow key, your CoCo
gives the check sum based on the length and content
of the program in memory. This is to check against the
numbers printed in the rainbow. If your number is
different, check the listing carefully to be sure you typed
in the correct basic program code. For more details
on this helpful utility, refer to H. Allen Curtis' article on
Page 21 of the February 1984 rainbow.

Since Rainbow Check PLUS counts spaces and
punctuation, be sure to type in the listing exactly the
way it's given in the magazine.

512K BASIC

(For 128K & 512K Computers)

From the authors of Word Power 3.2, the best-selling Word Processor for CoCo 3, comes a revolutionary programming tool!

Do you have a 128K or 512K CoCo 3? Are you being told that Basic will even run at double clock-speed and automatically slow
you could only use 22K from Basic?? Don't believe it! ! down for printer and disk operations.

Lets face it. You bought your CoCo 3 so you could get better
graphics, more speed and more MEMORY. Unfortunately as it
comes, the CoCo 3 only allows you to use 22K for Basic
Programs, A big disappointment for Basic Programmers.

Introducing the revolutionary 512K Basic. It gives you up to 80K
Basic program/variable space (64K for Basic Program/16K for
variables) on a 128K CoCo and over 400K (384K Basic Program
Space & 16K Variable Space) on a 512K CoCo! There are no
new commands to remember and approximately 90-95% of the
existing Basic Software will run without any modifications. 512K
Basic is completely transparent to the user. You won't even know
its there until you realize that you were able to type in a massive
Basic program without the dreaded ?OM Error. And 512K

Step up to 512K Basic. It's the tool you need to tap the full poten-
tial of your CoCo 3. 512K Basic Requires a 128K or 512K CoCo
3 with a disk drive. OS9 is NOT required. Only $39.95

3 Fabulous Bargains!

These specials will be withdrawn without notice. Don't miss them!

The Dazzling Word Processor

The Famous Graphics Creator

Max-10: the Rolls-Royce of word processors. The only one with true
graphic capability and dozens of type styles. Using your dot matrix printer
you get from tiny footnotes (6 point) to big titles (24 point).

The Rainbow review (1/89) said: "An incredible job of providing
power, flexibility and speed in a program that is as easy to use as it is
to pronounce! ... Max-10 takes a back seat to none, and is beyond
comparison with most." Max-10, the only word processor with "What
You See Is What You Get". A word processor you will love at first sight.

CoCo Max III: now a classic and probably the most popular CoCo pro-
gram ever. If the price was the reason that stopped you before, this special
will delight you. Listen (Rainbow 3/88) : "There are no limits to what you

Desktop Publishing: together, CoCo Max III and Max-10 form an
unbeatable system for reports, flyers, invitations, greeting cards/signs,
newsletters, etc. It's far beyond anything you've ever seen on a CoCo.

Here is one of the hundreds of unsolicited letters we got: "Max-10
and CoCo Max III are wonderful. They are the first Color Computer
products I have purchased that were even better than I hoped for."

At Colorware, we all work hard to make you feel that way and we
thrive on your appreciation.

About Max-10

What the CoCo Community needs is a word
processor that's rock solid blindingly fast,
feels like a Macintosh, makes all the others
look boring, and does not cost $80
Max-10 is just that and more. It allows on
screen mixing of graphics and text, large
headlines, multiple columns and full page
preview (with graphics).
We swear that Max-10 will add excitement
to your word processing, and that's no small
task!

Text for Graphics

By Jack D. Welsh

Lots of great graphics programs
have been published by THE
RAINBOW, and many times while
using these programs I've wished that I
could add text to my creations. I wrote
this program to do just that.

The program will work on any system
consisting of at least 32K Extended
Color BASIC and a cassette recorder or
disk drive system. For printouts you'll
need a printer and a screen dump pro-
gram compatible with your printer. [See
Richard Lack's "Get the Picture With
Gemini Screen Print" (May 1985, Page
45); Mark Sullins' "Picprt: Good
Things Come in AU Sizes" (May 1985,
Page 72 for dot-matrix printers)', John
Handis' "A Full Page Dump for the
DMP-I05" (May 1988, Page 92); and
David Fitzsimmons' "Penumbral
PrintsVor the Gemini Wx (May 1986,
Page 95.] After typing in the listing, save
it to a couple of disks so you won't lose
your work.

When you run the program, you will
see a display of the PMODE 4 graphics
pages. Press SHIFT and CLEAR to clear
the screen if it doesn't contain a picture
or contains memory garbage. You are
now in the Position Mode. In the center
of the display you will observe a blink-
ing pixel.

Now press I and then 0. This adjusts
the cursor movement to increments of
10. The cursor will move 10 pixels in the
direction of the arrow when you press
an arrow key. Pressing any other
number key in conjunction with the 1
key will set the cursor movement incre-
ment to that number of positions. If the
cursor reaches the far right side, it will
jump to the far left side if pressed again,

Jack Welsh is an income tax consultant
who learned programming through
reading publications and manuals.

and vice versa. On the top and the
bottom of thedisplay this does not
occur; the cursor merely stops at the top
or bottom.

You may now use the arrow keys to
position the cursor anywhere on the
screen you want to place text. Press ALT
to jump into the Text Mode, and type
your message or desired text. Press @
and then type some more. The @ key
switches text sizes up to the fifth size
and then starts back over at the smallest
size.

To return to the Position Mode, press
CLEAR. You can move the cursor to
another position on the display to add
more text. To load or save a picture, get
into the Position Mode and press L or
S, respectively.

To place text onto an already saved
picture, make sure that the desired
picture file is in one of your disk drives.
After loading this program press L.
Follow the prompts and the picture will
pop onto the screen; you can then add
text anywhere on the picture you desire.

THE RAINBOW May 1989

After completing your masterpiece,
press S. You are prompted to name your
creation, and it is saved to disk.

To save or load a file to or from a
drive other than the current one, just
type the drive number, a colon and the
picture filename. It will be loaded or
saved to the requested drive when you
press ENTER.

The characters used in this program
are made up of DRRW strings in lines 90
through 620. The variable array
CHflR$ (*) is used to define the DRRW

strings, where x corresponds to the
ASCII value of the key pressed. You can
use your imagination to define other
pictures or graphic stamps using DRAW
strings. For instance, change Line 150,
which defines the character A, to 150
CHAR$(65) = "R4U4L4D4". Now when
you press the A key, it will print a box
on the screen in any of the five sizes that
you choose with the @ key. Some of you
with artistic talent can make great use
of this feature!
To run the program on a cassette

system, change Line 1250 to 1250 CSA-

VEM PICNAME$,&H600,&H1DFF,0. Then

change LDADM in Line 1320 to CLDADM.

I have found this program useful to
make bulletins, posters, news ads and
banners that I then print out, using my
favorite screen dump program.

this program may be addressed to the

A space shuttle simulation that lets you be the pilot

Lunar .
Lander

• By Jeff Donze

s remote pilot, it is your job to land the
unmanned lunar landers at designated
landing sites. The company that has
hired you is counting on you to land its
expensive ships safely on the surface of the
moon. The valuable payloads these ships carry
are in your hands. If any cargo is lost or
damaged, you will be fired by the shipping
company. For each successful landing, how-
ever, you will be paid based on the landing site
and the type of cargo on board. After landing
at the five different sites, you will be promoted
to a higher cargo class. You then return to the
first site, but this time with a heavier load.
Remember, heavier loads increase fuel con-
sumption, but they also increase pay. Good
luck! This is Lunar Lander.

The program runs on any 128K Color
Computer 3. All you need to run it is a disk-
or cassette-based system and a joystick. Any
joystick will do, but Tandy's deluxe joystick
works best because it is self-centering. The
program can also be set to work whether you

Telewriter-128

the Color Computer 3 Word Processor

TELEWRITER: UNDISPUTED #1

If you've read the other word processor ads,
you've probably had your fill of cold lists of
features, and claims of ultimate speed, power,
and ease of use. So let's try to get past the
overblown claims and empty buzz words— with 2
simple facts:

Fact I: Telewriter is undisputedly the #1 most
popular word processor on the Tandy Color
Computers.

Fact 2: Telewriter's exemplary ease of use and
power have been acclaimed in numerous maga-
zine reviews and in thousands of letters and calls
from end users.

THE OTHERS DON'T UNDERSTAND

So why has Telewriter gained such a large and
loyal following, while other Color Computer
word processors have come and gone? Ironically,
our competitors' ads tell you exactly why.

For them, word processing is nothing more than
features and numbers. The longer the list of
features, and the bigger the numbers, the better
the word processor. Or so they think.

They just don't understand that power and ease of
use are not gained by tacking on random features
or throwing in freebie utilities or forcing you to
use a cumbersome mouse.

Real Power, true Ease of Use, and genuine Speed
can only be attained through thoughtful, logical,
intelligent design, attention to detail, and a com-
mitment to the act and the art of writing. That's
the Telewriter tradition, and that's the reason for
Telewriter's phenomenal success.

TELEWRITER-128: INTELLIGENT
DESIGN PERFECTED

And now, Telewriter-128, the latest Telewriter,
uses the added hardware power of the Color
Computer 3 to bring this intelligent design to its
logical perfection.

Telewriter-128 adds unsurpassed speed and
important new features to the already impressive
arsenal of Telewriter-64. Not just speed for
speed's sake, or features for the sake of
advertising— but speed where it counts and fea-
tures that make you a more efficient, more effec-
tive writer.

Rainbow magazine put it this way: "Tele-
writer-128 will set the word processing standard
for the Color Computer 3 because it is so simple
and user friendly. . . . The 81-page tutorial/user's
manual is nicely done. It is written in easy to
understand language but the program itself is so
easy. . . . Most people will be able to use the
software right out of the package."

TELEWRITER-128 OR DESKTOP
PUBLISHING

Desktop publishing is nice for adding pictures
and fancy fonts to newsletters or business
presentations— but its graphics orientation sacri-
fices some important capabilities when it comes to
working with words.

If your main concern is expressing ideas through
words (notes, letters, reports, papers, novels,
etc.), the dedicated word processing power of
Telewriter-128 still provides the most efficient tool
for the job. Each tool has its place— desktop
publishing for striking visuals, Telewriter-128, for
effective writing.

TELEWRITER-128 OR TELEWRITER-64

You can no longer afford to be without the ease,
power, and efficiency, that Telewriter brings to
everything you write.

Telewriter-128 for the Color Computer 3 costs
$79.95 on disk, $69.95 on cassette.

For the Color Computer 1&2, Telewriter-64 costs
$59.95 on disk, $49.95 on cassette.

FEATURES THAT MATTER: Telewriter's out-
standing design and its complete set of features, put
it in a class by itself, for smooth, efficient writing
and letter perfect printed documents. Telewriter-128
includes:

Unbeatable SCREEN PERFORMANCE: lightning
fast paging and scrolling, on-screen text that never
lags behind your typing, and a response that is
always instantaneous, no matter how much text is in
the buffer, or where you are in the document.

26 User definable MACRO KEYS type your often
used phrases and titles with a single keypress— saving
you time and freeing your concentration for writing.
User settable DUAL SPEED CURSOR moves you
anywhere on the line, on the page, or in the docu-
ment, fast or slow— you decide, with the touch of a
finger. Fast PRINT PREVIEW MODE shows you
text as it will print: headers, footers, margins, page
breaks, page numbers, justification— saves time and
paper and guarantees perfect looking documents
every time.

Instant, ON-LINE HELP summarizes all Tele-
writer-128 commands and special symbols. The On-
line OPTIONS MENU lets you instantly customize
the writing environment at any time to suit your
precise needs (Screen/character color, Monochrome
on/off, Key repeat/delay rate, 2 Cursor repeat/delay
rates, Case-sensitivity of search, Auto file backup
on/off, and more). A SINGLE FUNCTION KEY
takes you instantly to any menu, so you never have
to stop and think.

The 24, 25 or 28 LINE SCREEN DISPLAY option
lets you see 16% more on-screen text (28), or wider
line spacing (25). The auto-loading OPTIONS FILE
stores all your Macros, Print Format settings, and
Options Menu settings, so they are always there
everytime you run Telewriter-128. 3 pop-up STATUS
WINDOWS tell you cursor position, word count,

free space, etc.

The QUICK SAVE feature lets you instantly save
your current document with just 2 keystrokes and
without leaving the editor. CURSOR THROUGH
DIRECTORY to Load, Append, Rename and Kill
files— so you'll never type a filename after the first
time. HANGING INDENTS help you organize ideas
on the page more effectively. Also: Footers, Multiple
Print, Print to Disk, Key Click, Key Repeat, 40/80
Column Option, Overstrike, Word Delete, Nested
Macros, Definable Foreign and Math Symbols and
more. . . .

And, of course, Telewriter-128 incorporates all the
Features of TELEWRITER-64, like: Works with
absolutely any printer that works with your Color
Computer (1, 2, or 3). Uses simple Embedded Con-
trol Codes so all intelligent features of your printer
are easily accessed, including: Underlining,
Boldface, variable Fonts, Sub-script, Super-script,
Italics etc.

Format commands allow dynamically changing
Margins, Headers, Spacing, Centering, etc., any-
where in the document. Format menu sets Margins,
Spacing, Page numbering, Baud rate, Lines per
page, Justification. Chain Printing means the size of
your printed document is unlimited. Also Single
page and Partial Print.

Fast full-screen editor with wordwrap, text align-
ment, block copy/move/delete, global search and
replace, wild card search, fast 4-way auto-repeat
cursor, fast scrolling, forward and backward paging,
settable tabs, word and line counter, full error pro-
tection. Insert or delete anywhere on screen. Simple,
easy to remember, "mnemonic" Editor Commands.
Load, Save, Append, Partial Save files to disk or
cassette. Kill, rename and list disk files. ASCII file
compatibility.

are using a TV or an RGB monitor.
Before starting, read the appropriate
section below on loading.

Tape Owners

As I explain how to save, load and
modify this program, I will assume you
have read chapters 13 and 14 in your
Color Computer 3 Extended BASIC
manual. You need to know how to

CLOAD, CSflVE, SKIPF and EDIT.

If you will be typing in these pro-
grams, you should have an extra tape
handy to make backup saves. I'll refer
to this second tape as the backup tape
and the other as the main tape. If you
don't subscribe to RAINBOW ON TAPE,
you will have to type in listings 1 and
2 (landergg and lander) and remove
any errors. Do not run them, but save
them in order on the backup tape. If you
have an RGB monitor, change CM$ to
RB$ in Line 230 of LANDER. This tells the
program that you have an RGB mon-
itor. You are now done with the backup
tape. Put it in a safe place and keep it
in case something happens to the main
tape. Next, rewind the main tape and

type CLOAD "LANDERGG". Type SKIPF to

skip past Listing 2, LANDER — this is
important. Press Play and Record, then,
type RUN.

LANDERGG then saves two binary files
containing graphics on the tape. It will
take about 15 minutes to run and two
minutes to save, but you only have to
run it once. Rewind the tape and type
CLOAD "LANDER" and then type RUN.

Disk Owners

Start by formatting a new disk using
the D5KINI command. That is, put a
blank disk in Drive 0 and type DSKINI0.
Type in Listing 1, LANDERGG, and remove
any errors. (Do not run it yet.) Edit lines
980 and 1000; change C5RVEM to 5AVEM.
Now save it on your new disk. If you
have typed the program, you will want
to save it on another disk as a backup.
Next, type in Listing 2, LANDER. Change
CLOADM in lines 70 and 80 to LOfiDM. If
you have an RGB monitor, change CMS
in Line 230 to RG$. This tells the pro-
gram that you have an RGB monitor.
Save it on the new disk. Again, if you
have typed in this program be sure to
save it on another disk with LANDERGG
as a backup. Put the new disk back in
the drive and load and run LANDERGG.
This is the graphics generator; it saves
two binary files containing graphics to
the disk. It will take about 15 minutes
to run, but it only has to be run once.
All you have to do now is type

RUN"LANDER".

After you run LANDER, the program
loads the two binary files. Disk systems
load in only a few seconds, but tapes
take about two minutes to load. The
screen clears to black before you see the
title screen. Press the joystick button
and there is a short paragraph much like
one at the start of this article. Press the
button again to start the game.

"A s a remote pilot, it
is your job to land
the unmanned lunar

landers at
designated landing
sites. "

The screen clears to black for about
10 seconds while the computer draws
the first landing site. If your joystick is
not self-centering, push it slightly to-
ward the middle. If it is down too far
the ship's jet comes on, and it will go too
high, ending the game. At the top of the
game screen the computer shows the
Landing Site number and the Cargo
Class number. On the right side of the
screen is a red bar, the Fuel Level
indicator. At this point, you should see
the craft floating across the top of the
screen under the words "Landing Site."
Now is a good time to practice control-
ling the ship's angle by moving the stick
horizontally, that is, to the left and
right.

Notice that the joystick does not
work like an Atari. If you move it to the
far left, the ship's jet points all the way
to the left. It works the same to the right,
but if you put the stick in the middle,
the ship's jet points down. Move the
stick slightly to one side, and the ship
will turn to that side proportionally.
Pulling the stick down controls the
ship's engine.

When the game starts the ship is in
orbit, and you must slow it down to
make it fall. To do this, wait until the
ship is on the left half of the screen and
pull the joystick all the way to the
bottom-right. Stop thrusting when you
see that the ship is falling. Now the rest
is maneuvering. Try to get the ship so
it is slowly falling straight down directly
over the landing pad. While guiding
your ship use less thrust than you think

you need. Using too much thrust causes
the ship to shoot off too fast.

You can only land the ship on the
landing pad shown. The landing pad is
the gray and maroon rectangle. To land
successfully, the ship must be all the way
on the pad, not hanging off one side.
The ship must also be level. If the ship
touches while it is tilted at all it will
crash. Finally, the ship must go very
slow. Almost any left to right motion
will cause a crash. Accidents will also
occur if the ship is descending too fast
when it touches down.

If you have a centering joystick like
Tandy's, you may want to set the cen-
tering controls on the bottom to X-Free
and Y-Centering. This way the stick
moves freely from left to right, but
snaps back if you pull it down. If you
are using a cassette you should know
that pressing the Reset button will
destroy some of the graphics, and the
program will try to reload the two
graphics files. If you do press the Reset
button be sure and rewind the tape
before running the program.

For those of you who have some
experience programing on the CoCo 3,
there are two parts of this program. The
first part changes one of the HPUT
options to allow you to XOR graphics to
the screen. The second doubles the
buffer space used for HPUT and HGET.

The first change is simple. It changes
the NOT option for HPUT to XOR. XOR is
used to save time by making the pro-
gram run faster. When you put a picture
on the screen using XOR, you can erase
it by putting the same picture using XOR
again. One disadvantage is that the
background for the picture and the
screen must be zero, or the picture's
colors will not be correct.

This second change is more compli-
cated. I would not reccomend it for
beginners. However, if you have expe-
rience with CoCo 3 graphics you might
like to expand the Hi-Res GET/PUT
buffer. Doing so allows you to have a
greater variety of graphics in your
program. The book tells us that we have
7932 bytes to use for graphics storage.
If you look at the memory map on Page
311 you will see Hi- Res GET/PUT buffer
memory. A few lines down you will see
an area marked "Unused" by BASIC.
These two areas are the same size. If we
tell it to, we can have the CoCo use the
unused area as a secondary buffer. The
number that tells the CoCo what me-
mory to use for buffers is at SE0D4. The
dollar sign means hexadecimal; you can
use hex in BASIC by replacing $ with &H.
The normal value at this location is $34.

The number for the secondary buffer is
$37. To select the secondary buffer use
this command:

POKE &HE0D4,&H37

To go back to the normal buffer use:

POKE &HE0D4,&H34

Whichever buffer you select will be used
for HBUFF, HGET and HPUT. To trick the
CoCo into using the secondary buffer
you must mark it as free. To do this use:

LPOKE &H6E000,2SS:LPOKE &H6E001,
255

You can also mark the normal buffer
free with:

LPOKE &HGB000,255:LPOKE &HG8001,
255

When designing your own program
using this technique you should keep
the following things in mind. At the
start of your program mark both
buffers as free. This will eliminate
redefining errors. Select one of the
buffers and do all the HBUFF's for that
buffer. Then select the other buffer, and
do the HBUFF's for that buffer. As long
as you always use the same buffer sizes,
the graphics in the buffer will not be
affected. With all the buffers defined
with HBUFF, you can now GET and PUT
graphics to or from either buffer space
depending on which one you select.
Avoid pressing the Reset button. This
destroys some of the graphics in the
normal buffer space. If your program
only puts graphics on the screen, you
may want to divide the program into
two parts. The first part draws graphics
and HGET's them, the second part uses
the graphics from the first part.

This is the way Lunar Lander works.
Redefine buffers with HBUFF at the start
of each part. This way you only need to
run the first part once. CoCos with
512K can also use numbers from 0 to
$2F for even more buffer space. Re-
member, each area must be marked free
and needs its own hbuff's. To save the
graphics buffers, examine lines 880
through 1020 of LRNDERGG, and to load,
look at lines 70 and 80 of LfiNDER. When
saving and loading, the poke to SFFA2
intrudes on BASIC'S memory. To be safe,
always load and save in the first few
lines, and always type POKE &HFFA2,
&H3A before going on to the rest of the
program. If you don't, some of your
program will disappear.

Several users have recently asked
what networks are. We use Telenet and
Tymnet to get onto Delphi, but what is
a network? Good question!

Think of networks as really cheap
long-distance phone calls. Yet networks
are highly sophisticated, stretching
from coast to coast, linking your home
phone with the Delphi mainframes in
Boston. Networks gather the transmis-
sions from many computer users across
the U.S. and funnel them into Delphi at
10 million bits per second through fiber-
optic transmission facilities and even
satellites in some cases. Delphi sorts out
these transmissions, then prepares
responses for all of the users. It then
sends the responses into the network
and back to the users.

Networks such as Telenet and
Tymnet will never be as fast as commun-
ications between two computers. These
must divide their time between thou-
sands of users, while PC-to-PC connec-
tions involve only two computers.
Delphi is also a multiuser system and,
like any system, will slow down if
dealing with thousands of users.

Why, then, does Delphi use networks
like Telenet and Tymnet? Simple. It's
less expensive for the users. Networks
are an economical alternative to long-
distance calls. You have the option of
calling Delphi direct through your local
phone company, but most users don't
do that. While Delphi reduces your
connect charges by about $1.20 per
hour, if you call direct, youll have to
pay long-distance charges of about $15
per hour. It's a trade-off: The user gets
a somewhat reduced speed of perform-
ance, but also a lower phone bill.

To avoid slowdowns when many
users are online, try calling Delphi
during the nonpeak hours. Generally,
Delphi is busiest from around 9:00 p.m.
through midnight, Eastern time. If you
access the system at another time, you'll
find things run somewhat faster. Avoid
signing on when the Trivia Quiz game
is running unless you intend to play. TQ
is very popular and has dozens of
players online during its hours.

Boston. Telenet and Tymnet are tele-
communications networks that operate
throughout the United States. They are
two completely separate operations.

FAX Service Available on Delphi

At times, it is advantageous for me to
send a letter to noncomputer people

from my computer. The advantage is
speed — you can send overnight or
"next day" mail from your computer.

I looked around and was amazed to
find that Delphi has a FAX interface in
its mail system. Just blast a text file into
the system, and it will be FAXed to the
FAX phone number you specify.

For those who aren't familiar with
FAX, it stands for facsimile transmis-
sion. It sends a copy (facsimile) of a
sheet of paper to another machine
through the phone system. It's a copy
machine connected to your phone. To
use it, just feed the original into your
FAX machine, call the remote FAX
machine, and a copy of your document
is teleported to the other machine.

How do you use the FAX interface on
Delphi? It's easy, really. First, re-
member you must be at the main
DMAIL menu. (DMAIL stands for
Delphi Mail.) If you're at the CoCo SIG
prompt, you can get to DMAIL by
typing, go dmail. If you want to enter
the FAX system directly, you can type
go dmail Fax and youll be there.

Sending text messages to Group III
facsimile machines requires you to
know the area code and phone number
of the FAX machine you are calling for
messages destined to the United States,

THE RAINBOW May 1 989

Canada and the Caribbean. For inter-
national FAX, you need to know the
country code, city code and phone
number of the destination terminal,

A FAX message can be created in
your workspace and sent at the filename
prompt, or it can be typed live. The
same message can be sent to multiple
FAX machines by simply entering each
destination number when prompted.
FAX messages may be up to 50,000
characters in length. That's a lot of
information.

If you want to include page breaks in
your copy, enter /page as a separate line
of text at each appropriate place in the
message.

The rates for sending FAX messages
are as follows:

Destination

First

Additional

Page

Half

Pages

United States

$1.25

$0.50

Canada

$2.00

$1.00

International

$7.00

$2.00

A page is defined as 2500 characters,
a half-page as 1250. Each FAX sent to
multiple numbers will be billed at the
above rates. You can send them
throughout the day, generally within
minutes. You will receive notification if
your FAX is not sent.

There are all kinds of uses for this
service — Valentine's Day messages, or
if you forget someone's birthday and
want to send a "quick card" via FAX.
Business uses are almost endless, the
best benefit being the speed of informa-
tion flow.

Changing of the Guard

For those who have not read Forum
Message 48439, 1 have elected to retire
from my duties as the Database Man-
ager on the RAINBOW CoCo SIG. With
a new job, I don't feel I can do justice
to normal database duties any longer.

Replacing me will be Tim Koonce,
whose username on Delphi is TIM-
KOONCE. Tim is a graduate student at
Berkeley studying mathematics. Since
he is a frisbee freak, he should have all
the qualifications to handle the "quirk-
iness" of our databases and to field user
questions.

Assisting Tim will be Eddie Kuns
(EDpiEKUNS) and Dave Archer (DAVE-
ARCHER), so please address your ques-
tions to them concerning the database.
Jim Reed (J1MREED), Marty Goodman

(MARTYGOODM AN), Greg Law (GREGL)

and Rick Adams (RICK ADA MS) will also
be online to help out as needed.

Please join me in welcoming Tim to
the staff of the CoCo SIG. I'm sure he'll
do a fine job! □

May 1989 THE RAINBOW 41

And they 're off!

CoCo Derby

By Joe Wilensky

* or those of you who can't always
go to the races as often as you'd
like, here's an entertaining alterna-
tive: a day at the races at the TRS-80
Raceway! Place your bets — the CoCo
Derby is about to begin!

This game runs with a 16K Color
Computer with Extended Color BASIC.
The game starts with the title screen, a
few musical tones and the message
"Setting up". You are then asked if you
want to use the speed-up poke during
the running of the race. Each race is

Joe Wilensky is a political science major

Binghamton. His other interests include

42 THE RAINBOW May 1989

about a minute and twenty seconds
without the speed-up poke, about a
minute with it.

After deciding whether or not to use
it, choose the number of races to run in
the game (as many as you want), and the
number (1 to 4) and name of each
player. If you have less than four play-
ers, the computer will play the others.

After selecting the players, a score-
board appears with columns for the
name, wallet, horse bet on and amounts
bet for each player. The players now
choose from four horses. You can bet on
any one you want, even if someone else
has picked it. The players taken by the
computer bet and pick horses automat-
ically. Then each player places the
amount of his or her bet. You can't bet
more than you have in your wallet, and
any player who loses all of their money
has to drop out of the game, which
means no more betting or picking
horses. With bets made, you are told to
press ENTER to start the race.

The PMODE 4 screen appears and the
racetrack is drawn, with four separated
lanes. The top lane is for Horse I, the
second for Horse 2, and so on. A shor-
tened version of the call to the post is
played, twice for the first race, once for
all other races. The horses appear one

at a time, drawn with detail and a rider.
After a short delay, a low tone sounds
— and they're off!

The running horses actually move
their feet and bob their heads. This is
achieved with GET -PUT, using two sepa-
rate figures of a running horse. During
the race the pictures alternate quickly,
giving speed and animation to the
horses.

There is a clearly marked finish line
and as each horse hits it, a musical tone
plays and the number of the horse is
ranked as it finishes. After the fourth-
place horse crosses, there is more music.
Push any key to return to the score-
board. Each player's wallet is adjusted
accordingly; those who don't win lose
the amount they bet from their wallets,
and those who win gain their wager.

Betting for the next race begins, and
that is how the game goes. At the end
of the last race, the scoreboard appears
and the computer states who has won
and the player's number, and more
music is played.

"I cannot imagine the CoCo 3 without ADOS-3;
it would not be a complete machine."

The RAINBOW, July 1987

You've moved up to a CoCo 3. A powerful new machine. Now, It's time to
give BASIC a shot in the arm. with ADOS-3. Wouldn't it be nice to turn on your
machine and be greeted by on 80-column display, in the colors of your
choice, with your own custom startup message? To run routinely at 2 MHz
(double speed) without having to slow down for disk and printer operations?
This and much, much more is possible with ADOS-3, our CoCo 3 adaptation
of the acclaimed original ADOS, which shares the original's virtual 100%
compatibility with commercial software. After customizing ADOS-3 using the
provided configuring utility, you can have it burned into an EPROM that plugs
Into the Disk BASIC ROM socket, or just use it In RAM as a disk utility. (EPROM
+ burning will cost S 15-20; we provide Information concerning how you can
have this done,) Supports double-sided drives (35, 40, or 80 tracks). FAST and
SLOW commands, auto line number prompts, RUNM command, keystroke
macros, arrow-key scroll through BASIC programs, auto-edit of error line, and
many more valuable features,

Print invitations, flyers, classified ads, etc.
in any style you want

Having a

Party?

By R.J. McCorkle

/Invite is a program that lets you
create a series of 33 lines of text,
choose the print style for each line,
print four copies per page (with or
without names), and save the "invita-
tion" to tape or disk.

Either type in and CSAVE the program
(SfiVE for disk) or CLORD it from tape
(LOAD for disk), then type RUN and press
ENTER. The screen asks what type of
printer you are using; answer by press-
ing the letter A, B or C of your choice.
If you don't have a DMP-105, DMP-
130 or Epson RX.-80, there are tips later
in the article for modifying the program
to match your printer.

The main menu should now be on the
screen. To create the invitation, press C.
When it is printed, the invitation starts
at the top line of the page and ends at
the last line of the page, so you may
want to leave the first and last few lines
blank by pressing ENTER when asked
for' a line.

There are 33 lines available. Type in
the words you want on the line, then
press ENTER. The font (size and style)
menu appears with the line at the top
of the page. Press the number of the font
you want and a graphics block appears

RJ. McCorkle went into "semi-
retirement" three years ago to concen-
trate on programming. He is also a
"high-tech" fix-it mart, who tries to
replace blown fuses in cash registers,
video games, cable TV equipment, etc.

by the number. To turn off a font when
the graphics block is on, press the
number again and the graphics block is
erased. You can use as many of the fonts
as you want, but only one of pica, elite
or compressed will appear. If ndiie of
these three is chosen, pica is selected.

Press N or E when you are finished
with that line (the E choice is used
during editing so that you don't have to
go through all 33 lines). If you want to
re-enter the line, press R. When you get
33 lines in memory, the program goes
back to the main menu. The invitation
can now be saved to tape or disk, edited,
viewed on the screen or printed. Press
the letter of your choice. If you choose

Table 1: Program Description

|to print, the screen asks if you want it
f |)rihted with names or without. Press N
for names or W for without. If you want
it without names, you are prompted to
enter the number of pages you want.

Four copies are printed per page. Get
the paper perforation just above where
the first line will be printed. The pro-
gram uses all 66 lines usually available
per page. Each line of print should come
out centered in its section of the page.

If you choose to have names printed
; in the invitation, you are prompted to
! $nter the line number (1 to 33) where
you want the names printed. The names
will replace anything already on that
line, so be careful of your choice. Enter
each name, then enter XX and the print-
ing begins, putting a different name in
each invitation.

The major working part of the pro-

gram is in lines 100 to 187. (See Table
1.) This portion is used during creating,
editing and loading to determine what
fonts are to be used and to add the
printer codes and spacing to the words
on each line. The font menu works by
peeking the video-screen memory loca-
tion to the right of the number pressed
and poking a graphics block (169) if the
space is blank, or poking a blank video
code (96) if it is not blank. When E or
N is pressed, or if loading, the memory
location by each number is peeked. If
it has (169) (the graphics block) in it the
printer codes and spacing for that
choice are added to the words, Then the
choice's flag, F( 1-9,1-33), is set to 1.

The first part of the variable corre-
sponds to the font number choice and

the second part to the line number. (See
Table 2.) The text is saved in one
variable matrix, N$( 1-33), and the line
with printer codes and spacing are
stored in another, NJ$(l-33). The
words, variables and font flag variables
are used for saving the invitation to tape
or disk.

The printer codes are kept in lines
8000 to 9020. F$ ( l , l ) is the code to turn
pica on and F$(l,0) turns it off.
F$(2,i) turns elite on and F$(2,8)
turns elite off and so on. The labels for
the fonts are stored in FT$ ( 1 -9 ) . Line 22
establishes the labels common to the
three printers used. The other labels are
in the lines with the printer codes (8000
onward). As an example, to change

NLQ-PICfl to NLQ-ELITE for the DMP-

130, edit Line 9015 to read:

9015 F$(5,1)=F$+CHR$(29) :F$(5,3)
=E$+CHR$(19) :FT$(5)="5 NLQ-ELITE.

To change one of the printer types,
change one of the names in Line 25, then
change the appropriate subroutine to
the proper codes: Sub 8050 for DMP-
105, Sub 9000 for DMP-130, and Sub
8000 for RX-80. If you want to speed
up the program a little and you have
Extended Color BASIC, change the
following lines:

Build this adapter to use Wo Co Cos
with one disk drive

Wow!

One Disk Drive, Two CoCos

By Jeff Baier

For many CoCo 3 buyers, their
purchase means stashing away
the CoCo 2, leaving it untouched
in the dark corner of a closet to gather
dust. After all, most folks usually have
only one disk drive, and it is now
plugged into the CoCo 3. Well, the time
has come to fish out the old CoCo or

even buy one.

You can now use one disk controller
with two computers by transferring files
via the cassette jacks of the two comput-
ers. It's not as simple as its sounds,
though. The input is 1 to 5 volts and the
output of the cassette port is only 800
mv. I first made an amplifier that would
raise the 800-mv signal to the required
5 volts, but the corresponding circuit
did not work. This problem was even-
tually solved by removing the amplifier
from the circuit.

Figure 1 shows how simple the circuit
is. It has two distinct, identical sides.
Resistors 1 and 2 are the most important

Jeff Baier is an electronics technician
who lives in Ballston Lake, New York.
In his spare time, he likes building small
circuits and writing programs for him-
self and his family.

components in the circuit, providing
matching input impedance for the
cassette output. They actually boost the
ouput so much that the signal must be
reduced a little prior to being sent to the
other computer. The other resisters, R3
and R4, reduce the signal to the oper-
ating level of the other cassette input.
CI and C2 are used for coupling to
prevent DC connection of the two
computers. Finally, Jl and J2 are 5-pin
DIN plugs referenced to a view of the
port on the back of the CoCo. (If you
have problems figuring this out, see
Introducing Your Color Computer, the
manual enclosed with your CoCo 3.)

Construction of the adapter is easy,
requiring very few parts. All the items
in Table 1 can be found at your local
Radio Shack and purchased at low cost.
I used electrolytic capacitors and can't
guarantee that film capacitors will
work. Any circuit board will work. I
recommend buying the smallest and
cheapest you can find. When construct-
ing the circuit, give yourself enough
wire to make the distance between your
computers. Also, be sure the wire you
use gets wrapped together from the plug
to the circuit board. This will save you
a lot of problems by preventing a spa-
ghetti of wires from collecting behind
your computers. Four-conducter phone
cable will eliminate this problem, too.

After constructing the adapter, there
is not much more to know before
transferring programs from one to the
other. Loading and saving files can be
broken into three categories: 1) BASIC
programs, 2) machine code and 3)

May 1989

interfacing the computers with OPEN and
CLOSE statements.

Have the adapter plugged into both
CoCos and your disk drive plugged in
to the CoCo 3 and we will transfer to
CoCo2. (BASIC programs are some of
the easiest to load as long as they don't
interface with disk files or load other
programs.) To transfer a program, load
it from disk to your CoCo 3. Once the
program is loaded, go to your CoCo 2
and type CLOflD and then press ENTER.
Now go to your CoCo 3 and type CSflVE.
It's that simple. After a short time the
program will be in your CoCo 2's
memory, and you can run it. Then you
can go back to work on your CoCo 3.

Machine-language programs are a bit
more complicated. In order to save a
machine-language program, you must
know its start, end and execution ad-
dresses. This is not a big problem if you
wrote the program yourself. If not, read
the disk one byte at a time to figure out
those three addresses. [For more infor-
mation see "Follow The Bread Crumbs"
(February 1988, Page 108), by Dennis
Weide.] Then type CLOfiDM on your

CoCo 3 to send a machine-language
program to it. Autoexecuting pro-
grams, however, do not provide for any
BA*S1C statements except the L0ADM and
then the program takes over. I have not
come up with a solution for this prob-
lem yet but am working on it.

The last category is interfacing two
computers. This is simple as long as you
try to open a file on the reading com-
puter prior to trying to open it on the
sending computer. The reading comput-
er will wait for a file to be present, while
the sending computer assumes that its
writing media is ready. Once the file is
open, the same rule applies. Use timing
loops between reads that ensure it.

Once you start transferring files,
you'll be amazed at the uses. One exam-

ple is an interactive game, written in
BASIC, between two computers that pits
two people against each other. You can
transfer any variable used by either
computer. This tends to program a lot
easier than a null modem. Keep in mind,
too, that this project will work for
transferring files between any two
CoCos.

I plan to come up with some software
to utilize this option more fully as well
as speed it up. It's a little work for a real
bargain. □

Educat i on M otes

This month's article addresses students
above the fourth grade level, though it's not
necessarily a kid's program. It concerns
fractions, those mathematical obstacles we
were introduced to in the early grades, and
tripped over throughout high school.

There are students naturally inclined
toward math, like ducks to water; and those
who have phobias about it — sweaty palms,
shortness of breath, migrains. Advanced
math students may easily alter this program
to provide more challenge, while more
timid students, on the other hand, may
discover that practicing and reviewing
examples on the computer is a refreshing
and non-threatening experience.

A short review of fractions is included
and is helpful before beginning the lessons.

There are two main rules for solving
these problems.

Principle 1: If fractions have the same
numerator, the fraction with the smallest
denominator has the greater value. For
example:

3/5 is greater than 3/7
4/9 is less than 4/5

Principle 2: If fractions have the same

A refreshing way to
confront fractional fears

Fraction
Action

denominator, the fraction with the larger
numerator is the greator. For example:

7/10 is greater than 3/10
3/8 is less than 5/8

Most of the time, the fractions will not
immediately fall into either of the above
categories. To compare the value of such
fractions, both must have common denomi-
nators. This new denominator should be a
number which both of the original denomi-
nators will divide into evenly. One possible
denominator can always be found by find-
ing the product of the two original denomi-

nators. For example:

Compare 2/3 and 4/5. A common de-
nominator is the product of 3 and 5, which
is 15. Therefore:

2/3=10/15 and 4/5=12/15

Since 12 is greater than 10,4/5 is greater
than 2/3.

Also included is a third rule, which is
really a shortcut that 1 teach to more
advanced students . By examination, one of
the fractions may clearly be less than 1/2
and the other clearly greater. For example,
3/7 is less than 1/2 since half of seven
is three and one half. Seven-tenths is more
than 1/2 since half of ten is five. Thus, 3/7
is determined to be less than 7/10 by this
inspection alone.

The program contains 10 examples of
how to compare fractions. The student
determines if the two fractions are equal or
whether one is greater than the other. To
indicate an answer, press the =, < or > sign
on the keyboard. After the 10th example is
completed, a scorecard is displayed, help-
ing the student keep track of progress.
Lines 280 and 290 may be deleted if you
prefer to omit scoring.

The student can work out problems
mentally or on paper. Because the denomi-
nators are no larger than tenths, after prac-
tice, it should be easy to work them out
mentally. To increase or decrease the range,
simply change the random limits of the four
variables A, B, C and D accordingly.

Desktop Publishing
Comes to the CoCo

By Jeffrey S. Parker

In 1984, with the introduction of the
Macintosh, desktop publishing became an
affordable reality for both businesses and

Jeffrey S. Parker has been involved with
computers since 1976 and CoCos since
1981. He is the Director of Computer
Education at The Parker Academy in Sud-
bury, Massachusetts. He is also a lecturer
at Northeastern University in technical
communications. A noted freelance writer
and editor, Mr. Parker is a Certified
Computer Professional and holds degrees

University in England.

the individual user. The CoCo, busy be-
coming smaller outside and bigger inside,
was being used for graphics, adventures,
arcades and simulations, full-featured word
processors, RAiNBowfests and more.

Now desktop publishing has arrived in
earnest for the CoCo. Not only can we print
fabulous graphics designs, we can mix them
with text in different styles,types and sizes.

What is Desktop Publishing?

The first thing most people think of
when you say "desktop publishing" is a
newsletter. However, desktop publishing
is not a "thing" at all. It is a process, or
series of processes by which we arrive at a

The colorful, menu-driven display of
Newspaper Plus.

These are only typical examples of the
concept of desktop publishing. Let's as-
sume for this article that this is our descrip-
tion of desktop publishing. Cut down to its
very basics, it is publishing using a per-
sonal computer. Publishing involves many
different elements, the overall goal being a
printed document. Typesetting is one of
those key elements. Both the type of print
(font) and its height and width (point size)
are important too. Layout, or positioning
on a page, is also important and must work
in conjunction with the fonts being used.
There is also the question of graphics.
Graphics are anything other than text. They
can be drawings, photos, digitized images,
sketches, cartoons, diagrams, anything that
is not pure text. Most desktop publishing

These samples were produced with the combined efforts of CoCo
Max III and Max-10. The photos below (left) show the WYSIWYG
display of Max-10 and the full-page preview (right) of the sample
document.

58 THE RAINBOW May 1989

requires some form of artwork or graphics
to make a completed document.

One of the great advantages of desktop
publishing over word processing packages
has been its ability to combine text with
graphics and to create multiple columns on
one page, like a newspaper.

Only a few years ago, there was no easy
way to do that with the popular word proc-
essing packages available on the CoCo
market. One had to obtain expensive soft-
ware that was usually short on all the fea-
tures that you needed, except that particular
one of making columns. Now, many good
word processing programs will do that rela-
tively quickly and easily.

Columns alone are not enough though.
The software must be flexible enough to
wrap text around graphics within and out-

side columns, and even have blocks of text,
such as headings, that are not within those
columns. It's a tall order!

For serious desktop publishing, options
supplied with many packages are rarely
enough. There are a few more clip art
images needed to get that special point
across; one more font to make it perfect. So,
if you want to use artwork or fonts from
other packages, the import/export feature
is needed, which allows you to import or
export fonts, clip art and text to or from
other programs.

But what if you want to incorporate text,
fonts or graphics from a different com-
puter, like a Macintosh or PC? Then you
need the ASCII save/load feature as well.
ASCII is the American Standard Code for
Information Interchange and it allows any

computer to save a file of a given font, text
or graphics in ASCII format, so other
computers with the ability to save ASCII
files can read it.

Just as important is the feature that al-
lows you to see the finished document on
screen before printing. WYSIWYG (pro-
nounced wi-see-wig), an acronym for What
You See Is What You Get, describes the
process of viewing on screen — either
continuously, or in the display mode —
what your finished document will look
like. How can this be done? The computer
actually thinks of the screen as a device
(printers, disk drives and modems are
devices, too), so when you ask to view your
document, the computer prints it to the
screen instead of to the printer or to a file.
No desktop publishing software is worth

Newspaper Plus

The Hi-Res preview option of Newspaper Plus (below, left) gives a
full-page view of your work, but with some loss of text legibility. It is
great, though, for getting a feel for what the document will look like. The
Lo-Res option (below, right) increases legibility and allows scrolling
through the document.

its salt without some form of this feature.

Lastly, and certainly quite important, is
the actual printout of the document. The
question here is not so much what kind of
printer you have, but does the software
communicate with or drive your printer?
Of course, the type of printer you have will
make a difference in the quality of the
document and how fast you can print it.

If you intend to pursue desktop publish-
ing, you cannot use a letter quality printer
(LQP) such as one of the Tandy DWP
series printers, also called daisy -wheel
printers. A printer with a wheel or thimble-
like print head can only print letter quality
documents like a typewriter — no graph-
ics, no fancy fonts. So be sure that you have
a laser, color or dot-matrix printer.

Does the software need all of these fea-
tures to be desktop publishing? No, not by
some standards, but yes by mine.

The Works
from Color ware

What It Does: The Works is a desktop
publishing teamup of the Max-10
word processor and the Co Co Max
III graphics editor, along with a large
variety of supporting font sets.
Analysis: This package is feature-rich,
extremely fast, easy to use and has a
true WYSIWYG display. It's a power
package that can outperform the
Macintosh in speed and features.
Requirements: 128K CoCo 3, one
disk drive, and mouse or joystick. A
second disk drive and an RGB mon-
itor are recommended.
CoCoConclusions: An excellent
package overall for Color Computer
desktop publishing, but it is also three
times as expensive as its nearest com-
petitor. It is well-suited for ad layouts
and graphic design.
Pricing: The Works, including Co Co
Max Max-10, Max-10 Font Set
and CoCo Max Font3, $149.95.
For more information, see the review
of Max-10 in the January '89 RAIN-
BOW, Page 118 and the review of
CoCo Max III in the April '88 issue,
Page 129.

The Power of the Printed Word

For the Color Computer there are only
three packages that meet the criterion for
complete desktop publishing packages —
The Works from Colorware, Newspaper
Plus from Second City Software and Home
Publisher from Tandy.

The Works

The Works package includes Max-10, a
full-featured word processor and CoCo Max
III, a graphics creation program. Packaged
together, it forms the most powerful desk-
top publishing package available for the
Color Computer.

Max-10 has pull-down menus, dialog
boxes, full mouse control and instant re-
sponse. It has full-display capacity, a spell
checker, text wrap, multiple columns, lock
protection, global search and replace and
the capability to import all types of files.

The Newspaper Plus
from Second City Software

What It Does: The Newspaper Plus is
a desktop publishing program that
uses a structured layout to let users
produce newsletter-type documents.
Analysis: The program is easy to use
and versatile. It is supported by exten-
sive clip art and fonts. It includes a
graphics conversion program, but the
size of an image to be converted is
limited.

Requirements: 128K CoCo 3 and one
disk drive. An RGB monitor and two
disk drives are recommended.
CoCoConclusions: The Newspaper
Plus is a full-featured desktop pub-
lishing package that, on the whole, is
very reliable.

Pricing: The Newspaper Plus, $48.95;
Graphics Disk I, $19.95; News Art
disks A through Z, $9.95 each or $100
for 26-disk set. Registered owners of
CoCo Newsroom may upgrade to
Newspaper Plus for $19.95.
For more information, see the upcom-
ing review of The Newspaper Plus in
the July 89 issue of THE RAINBOW.

You can find out how much memory
you have left by looking at the "gas gauge"
type display. It is a good idea to check this
before bringing in a graphics file, as mem-
ory goes quickly with all those pixels.

CoCo Max HI, on the other hand, is a
graphics design package that incorporates
sophisticated text formatting capabilities,
but is primarily designed for graphics de-
sign. It includes 28 tools, 16 colors, 14
initial fonts, plus template tools, from ver-
tical arcs to the regular and irregular quad-
rilaterals, ellipses on and off, and your run-
of-the-mill rays, boxes, circles, lines drawn
in any width, animation and color cycling.
CoCo Max 111 has graphics capabilities to
paste files or pictures of nearly any type
into the body of a document, resize the
image and wrap text around it. You can
import/export graphics files in almost any
format you can name. It has 40 brush shapes

Home Publisher
from Tandy

What It Does: Home Publisher is the
only OS-9 desktop publishing soft-
ware for the CoCo. No OS-9 expe-
rience is needed. It will run under
Multi- Vue.

Analysis: It has flexible configura-
tion, 14 fonts, 37 graphics images and
64 colors. The user interface for
controlling screen viewing and text
entry is a bit clumsy, and the program
is somewhat limited. However, it is
capable of impressive results.
Requirements: 128K CoCo 3 and one
disk drive. Performance is enhanced
with 512K RAM and a mouse or
joystick. An RGB monitor is recom-
mended.

CoCoConclusions: Home Publisher
works in the Multi- Vue environment,
which means you can edit several
documents at the same time.
Pricing: Home Publisher, $39,95;
additional printer drivers, $19.95.
For more information, see the review
of Home Publisher in the July '88
RAINBOW, Page 122.

THE RAINBOW May 1 989

and dozens of fill patterns that you can
change or create.

CoCo Max III allows you to use hun-
dreds of fonts, four disks full of them, plus
what comes with the program, and any
others you care to buy and translate to
CoCo Max III. As part of The Works pack-
age, Color ware is offering the 100-font set
for CoCo Max III at no extra cost, and the
36 Max-10 fonts, as well.

As an option, color printer drivers are
available for CoCo M ax II I for the Star NX-
1000 Rainbow, the CGP-220 and Okimate
20 at $19.95 each. These will drive 125
colors in the above printers. Otherwise, the
drivers included support IBM/Epson com-
patible; Radio Shack, including black and
white CGP-220; Gemini; andOkidata 182/
192 printers.

CoCo Max III includes and requires the
use of a modified Hi-Res Interface for its
operation. This allows fine control over the
screen with a mouse or joystick. Max-10
uses the modified interface, too, but also
requires a hardware key ("clicker") to be
plugged into the cassette port. This later
item is a form of copy protection. Both the
interface and the "clicker" are included
with The Works.

The Works package gives more graph-
ics, text, import and export capability, lay-
out and text/graphics integration than any
other software product for the CoCo.

It sounds as though The Works is like an
MS-DOS desktop publishing system be-
cause it is modeled after one. It raises a
serious question about why to buy a $2000
Macintosh with Macwrite, MacPaint and
MacPublish just to match it. I like chal-
lenges, so I brought in a respected friend,
who is a Mac user, and he nearly fell off his
chair when I showed him The Works. He
kept shaking his head and moaning quietly,
"My Mac can't do that.. .no, it can't do that
either."

But does this mean you should buy it?

The Men Behind the Max

Born in Paris, John Monin moved to
the United States some 13 years ago.You
could say he has a European perspective
on marketing software: "I wouldn't buy
junk, and I will not sell it," he says. "We
spend the money until the product is to
my satisfaction."

John has put his money where his
mouth is in this case. With the introduc-
tion of CoCo Max /// and Max-10,
bundled together with extra font sets,
Colorware has introduced what appears
to be perfectionist's software — The
Works.

Both CoCo Max III and Max-10 were
written by Dave Stampe, who tackled the
projects in his early twenties but has since
returned to school to pursue engineering
degrees. According to Monin, Stampe
would revise and revise the software until
he was happy with it. Even after pro-
nouncing a project finished, Stampe
would spend a weekend writing arid
rewriting 100 pages of code, just to add
one more feature. "I was really afraid that
he'd burn out," said Monin. "But he
really wanted to dohis personal best, and
he produced a program that is nearly
perfect."

John Monin's pride in Dave Stampe is
evident. "It is not how big a company you
have, or how majiy people you have
working for yoU — It is hoW thorough
you are. We are really pleased at Color-
ware that CoCo Max ///and Max-10 are
as good as they are."

Monin founded Colorware after the
emergence of the Color Computer in
1982, Originally, his Alpha Products

company supplied hardware interfaces
like clocks and speech synthesizers for
the TRS-80 Model I and III computers.
When Monin saw the CoCo gaining in
strength and popularity, his company
went all out to produce quality products
for it.

"Colorware was founded because I
wanted to bring the products we had
developed for the Model I and III to the
Color Computer," John said, reflecting
on the light pen interface and the Atari
joystick adapter that were the company's
first CoCo products.

CoCo Max and CoCo Max II were
written by Tim Jenison. Tim left Col-
orware to strike out on his own after the
development of CoCo Max II and is
now developing products for Amiga
computers*

Monin has pledged support to the
CoCo Community, saying that "as long
as there is a RAINBOW, there will be a
Colorware." He would not release infor-
mation on new products being devel-
oped, but he did hint at new pricing
structures for CoCo Max III and Max-
10 soon to be released, as well as a
rumored release of his products with no
copy protection schemes at all

"I use CoCo Max and Max-10 myself.
In fact, the next advertisements in RAIN-
BOW will be done completely using
Max" said Monin.

He went on to say that he had received
calls from a number of clients who are
using The Works to run their businesses
— doing ad and layout work, fliers and
newsletters. □

Not if all you want to do is make greeting
cards and signs. If you don't need all that
muscle, and you don't want to be an artist,
there are other alternatives. I like to use this
formula: The need must justify the cost.

The Works is the best, but at $149.95, it is
also the most expensive. Keep in mind
what you want and need as you make your
choices. If you want a more structured
layout to work with than Max-10 can give

you, The Works will not work for you. Let' s
take a look at why.

Newspaper Plus!

If you want to produce a newsletter for
your Boy or Girl Scouts, packed with infor-
mation and including a subtle graphics
punch, then the structured environment of
Newspaper Plus fits the bill.

The program comes with 22 fonts and
50 clip art pictures. There is a graphics disk
you can purchasefor $19.95 with 10 new
fill patterns, three new font sets and 50 new
graphics picture files.

Newspaper Plus is operated solely from
the keyboard, no mouse or joystick inter-
face is required. A conversion utility al-
lows changing graphics and font formats
into the Newspaper Plus format, but there
are size limitations on the imported graph-
ics image. Larger images must be cut into
sections or only a part of them may be
captured and used. One nice feature is a
utility called Grabber, which serves to grab
graphics images off a screen to be stored for
later use in a document.

Newspaper Plus is written mostly in
BASIC and gets it speed from machine
language subroutines. Newspaper Plus also
utilizes a structured environment, differing
from The Works, but similar to Tandy's
Home Publisher and with more options. To
use it, you must choose a layout from a
menu, which gets loaded into memory. A
typical layout might be two columns bro-
ken into four sections each, with a full-page
banner across the top, such as the newslet-

ter shown on Page 59. There is no free-form
environment; the document is built one
section at a time and then compiled for
saving, viewing and printing. Of course
this has some interesting mix and match ca-

pabilities since you always select which

built from.

I had one major problem with Newspa-
perPlus.When it hits a disk error on asave,
it crashes. So if you just spent an hour
designing the perfect section of your news-
letter, and there is a disk error, you are
unable to exit to the Type Up II program to
save the memory buffer to restart the pro-
gram. (I lost my work. I was so upset by
this, I tried the program on three different
CoCos, three different drive systems, and I
had the same problem time after time.) Ed
Hathaway of Second City Software is aware
of this and has indicated that a patch to fix
this problem will be available very soon,
and will be sent to all registered Newspaper
Plus owners.

Newspaper Plus supports a wide assort-
ment of printers, including the Radio Shack
printers along with the CGP-220, and un-
like any of the other packages we are look-
ing at, the Tandy LP- 1000 laser printer.
Support for Gemini, Star NX 1000 and IBM/
Epson compatibles is also included. There
is also a utility that allows you to design
printer drivers.

It has the best documentation for desk-
top publishing on the CoCo I have seen. It
includes a thorough manual and a begin-
ner's tutorial.

Tandy 's Home Publisher is a modest in-
troduction to desktop publishing for the
128K Color Computer, but works much

The Chief Editor of Newspaper Plus

The CoCo Community at large can
bear witness to yet another "Local Boy
Makes It Big" story — that of 16-year-
old Eric Wolf. Eric is sole owner and
operator of EAW Software, a company
formed to market his innovative software
creations.

Eric has been writing software for the
Color Computer for several years. His
first published program, Out In Font,
was published in the "Hot CoCo" section
of 80 Micro (now defunct) in 1986. This
was a program to generate new type
styles and fonts for creative printer
output. Could it have been a precursor
to Newspaper Plusl It may very well have
been.

A 10th grade sophomore at Lasalle
High School in South Bend, Indiana,
Eric stands over 6 feet tall and enjoys
basketball and a quiet family life with his
parents and three brothers and sisters.
Not yet certain where he plans to attend
college, Eric wants to pursue a degree in

computer software engineering or pro-
gramming. He has expressed a strong
interest in artificial intelligence, which he
studies in his spare time, and has taught
himself BASIC, machine language and
Apple Pascal.

Eric started programming on an old
gray CoCo 1 that his Dad brought home
when he was 10 years old. From there he
became interested in reading THE RAIN-
BOW and keying in programs, eventually
trying some programming on his own.
When he discovered that he had a talent
for it, he set out to write exciting soft-
ware.

Eric wrote one of the first commercial
products for the CoCo 3 when it came
out, CoCo Newsroom (now the updated
Newpaper Plus) — he was only 14 years
old at the time, incredible as it seems.
Originally marketed through Spectrum
Projects and Microcom Software, exclu-
sive rights are now owned by Second City
Software of Roselle, Illinois. Along with

Newspaper Plus and the accompanying
graphics disk, also written by Eric,
Second City sells other popular CoCo
software. Just released is another News-
paper Plus companion, News Art
which is scheduled for release at RAIN-
BOWfest Chicago.

Ed Hathaway, co-owner of Second
City Software with David Barnes, an
OS-9 analyst and programmer, is very
proud of Eric and his accomplishments,
and very pleased with the Newspaper
Plus product. He is generously publish-
ing a quarterly newsletter free of charge
to registered Newspaper Plus owners,
which includes sample newsletter
layouts, patches, fixes, upgrades and new
product announcements.

David is SysOp of the Second City
Software BBS, (312) 307-1519, which
lends additional support to the com-
pany's clients and serves as a local CoCo
club BBS.

better on a 512K Color Computer using a
mouse or joystick. Of the three programs,
this one runs the best on a monochrome
monitor. {Newspaper Plus is difficult to
read on some screens and Max-10, while
sufficient, loses something in the transla-
tion without color.) Remember, software
must be configured before it can be used
properly. If you just loaded up a program
and it looks strange, check the settings for
the monitor, printer, input device, drives,
etc.

Tandy Home Publisher operates in the
OS-9 level II environment, though you
don't need to own it or be familiar with it to
operate the program. It has flexible con-
figuration, 14 fonts, 37 graphics images
and 64 foreground and background colors
to set your RGB or Composite screen to and
has all the common word processing fea-
tures. The fonts are varied in size and style,
not as well done as some other packages.
The 37 images are well done.

This is the only Color Computer desk-
top publishing package under OS-9, but is
also the only one with no file translation
utility. The biggest problem is the speed at
which it operates. It is unbearably slow to
update, draw screens, draw pages, and so
forth, yet it is a good example of desktop
publishing. Its interesting user interface
enables the user to work with one portion of
the document at a time. Like Newspaper
Plus it has a structured but far more limited
range of layout patterns. There is some
compatibility and a program like OS-9 Cal-
ligrapher might come in handy here.

Printer support for Home Publisher is
limited to several of the Tandy DMP series
printers and an Epson RX-compatible
printer. In addition, there is a printer driver
disk available from Tandy for $19.95, which
has the following popular printer drivers:
Tandy CGP-220, C. Itoh 85 1 0 AP, Epson
MX-80, Okidata 20, Panasonic KX-P1090,
and the Star SG-10.

Tandy Home Publisher also works in
the Multi-Vue environment, which in the-
ory means you can edit several desktop
publishing documents at the same time.
However, there is a problem of keeping
track of where you are on the screen. You
may input some text, but it does not show
up because you are looking at a different
area of the document than where you are
putting the text. This program is also set up
to import text from any OS-9 word process-
ing program, though it's a good idea to
write it on something else and then import
it into the Home Publisher. Simple lines,
however, can be done within the program.

Extra, Extra!

There are many programs for the CoCo
1, 2 and 3 that will do great drawings or

Nancy Ewart on Desktop Publishing

Meet Nancy Ewart, freelance writer on
computer topics and CoCo user extraor-
dinaire. Nancy insists that she is a user,
not a programmer, and takes time out
from her busy schedule to talk to a
reporter from RAINBOW. When asked
about CoCo's desktop publishing pro-
grams, she confides, "I have used them
all, and I have started working on MS-
DOS machines, too." She adds, *Tm a
novice Ventura Publisher user really, and
all Fuse at home is the CoCo. 1 *

A relative newcomer to computers at
age 58, Nancy started on computers
about five years ago when she bought one
for her nephew. She found that she
became interested in them herself, and
now she owns four CoCos. *Tm an
OS-9 advocate,*' she says, "and the main
thing I've been seeing is what l would
have liked to have seen all along with the
CoCo. There ought to be an easier way
to run OS-9."

Nancy says she is disappointed that
there is not a better desktop publisher for
OS-9. "Home Publisher is very slow,"she
said. "There are none of the more usual
typefaces. The smallest type isn't small
enough, and you have no control of the

leading, which is the spaces between the
lines." Nevertheless, she insists that she
has learned a lot from using Home
Publisher and that the program has been
very important to her. She has taken the
experience gained and applied it to her
MS-DOS work. "A lot of what I've
learned in Home Publisher, Newspaper
Plus, and The Works crosses over to
Ventura, and vice- versa."

When asked what she thought about
Newspaper Plus, she said she thought it
was good, but she missed the mouse. "It's
a very good middle-of-the-road pack-
age," she commented, then added "CoCo
Max HI and Max- 10 are much easier to
use. 1 wouldn't fool around with anything
else." She also added that the combina-
tion sets of fonts you use with MaxAQ are
like the style sheets in Ventura Publisher
for the PC.

When asked if she used her CoCos for
any business or professional work, she
explained that she had done prayer
books, yearbooks, and page layouts for
national Girl Scout handbooks, adding
that she had recently taken art courses to
learn more about graphics design.

make fantastic fonts but, as mentioned al-
ready, unless they meet your needs they are
not practical.

I talked to several desktop publishing
users, and found a wide range of needs —
newsletters for clubs or organizations;
business or professional documents; and
for just pure fun, greeting cards, invitations
and banners. And for many of these proj-
ects, full-fledged desktop publishing pro-
grams are not needed. In such cases, sup-
plementary programs provide enough fea-
tures.

Calligrapher from Sugar Software, for
example, is designed to work only with
text. The Calligrapher programs include:
OS-9 Calligrapher, CoCo Calligrapher and
OS-9 Font Massager.

CoCo Calligrapher is a powerful font
filter, but is limited under our definition of
desktop publishing. Running under Disk
BASIC, you can type up to 17 lines of text
in one-half inch letters in one of three fonts:
Gay Nineties, Old English and Cartoon.
The editing capabilities are limited, de-
signed primarily to make flyers, invita-
tions, announcements, etc. It is compatible
with IBM, Epson, Gemini and Radio Shack
dot-matrix printers. OS-9 Calligrapher can
load multiple files and fonts (See Figure
1.), set margins, change directories, print
files to disk or to the printer, view files,
wrap text, justify left, right or center, print

in columns, etc. — a fairly full-featured
word processor.

OS-9 Font Massager is a package that
allows you to create new fonts, invert fonts,
double the width or height of a font, halve
the height or width, and convert fonts be-
tween OS-9 and Disk BASIC, to ASCII or
binary. And it works on a CoCo.

Of the three packages, the OS-9 pro-
grams clearly have more power and flexi-
bility. They include well-written manuals
and require only a very basic knowledge of
OS-9. Any individual package is short of
being a complete desktop publishing pro-
gram, but provides good typesetting and
font generation. There is always the option
to use the additional fonts available from
Sugar Software or fonts from other pro-
grams. The Calligrapher programs are
outstanding values if you have text-only
needs.

Get The Picture?

The Digisector DS69B and C-See 3.3
software from Micro Works is also more of
a sideline to desktop publishing. It has the
ability to create computer-readable images
using a video camera and special conver-
sion device. To understand how the Digisec-
tor works, think of it as taking a picture,then
converting it to a series of numbers that the
CoCo understands, reading it into the CoCo
memory and having the CoCo display what

May 1989 THE RAINBOW 63

Logan Ward's
Specialty Projects

Everybody seeMs to kno^ Logan
Ward for something. Whether it is for his
work at the Computer Center of Mem-
phis, Tennessee, his CoCo Cat and Max-
well Mouse cartoons from RAINBOW, or
the "world's only CoCo PC" at RAIN-
BOWfest, everybody gets a chance to
bump into Logan Ward sooner or later.

Logan's latest venture is clip art for the
CoCo, in the form of a package marketed
by Specialty Projects, a company he
helped form with a local Color Computer
users group. The package is called Art
Deli Library and is an assortment of 440
clip art images, sorted by theme, on 10
disks for $99.

Logan refuses to take full credit for this
release. "This was a real team effort,'* he
says. "It was mostly put together by
myself and my wife, Stacy Ward, and B.J.
Setton and his wife, Theresa, and also by
Bill and Terry Peck. We got together from
a local users group, just decided that
someone should do some real serious clip
art for the CoCo and make it available
to the general public."

While Art Deli has no documentation,
it does include a printout of each of the
digitized PM0DE4 images. These are ar-
ranged by theme on both sides of 10
disks. The themes include holidays, pets,
travel, love, sports and silly sports. "All
you do is convert them to whatever
graphics program you have," says Ward.
The images are all professionally ren-
dered high-quality drawings, and do in
fact convert readily to the different
desktop publishing packages included in
this article.

Specialty Projects will soon release a
utility disk for transferring the images
among different program formats, such
as Newspaper Plus, Home Publisher,
CoCo Max /// and Max- 10. The disk will

each of those coded numbers stands for,
much as a modem works.

Best results come from using a CoCo 3,
though the system works with other Co-
Cos. There are 64 levels of gray, and the
software changes the amount of gray in
different light intensity sections to give an
enhanced image.

The Digisector comes in a ROM pack,
but requires special software to run. Be sure
your Multi-Pak has the required CoCo 3
upgrade, or you may get some strange
results. Once you are finished editing your
image, you can save the image on disk.
Programs like Magigraph, CoCo Max III
or Graphicom can then edit the images and
bring them into various programs for fur-
ther editing.

It supports Radio Shack and IBM/Ep-
son-compatible printers. The reviewer rec-
ommends a four-head HQ VCR or a high-
quality Camcorder for capturing the video
images to get crisp, clear resolution. How-
ever, any video source, even a TV can be
used and still produce good results. (See
Figure 2.)

What makes this program so valuable to
desktop publishing is that it can be used to
make clip art or graphics images. An image
can be imported into a desktop publishing
program and integrated into a document.
There are enough conversion utility pro-
grams available so that once you have the
image translated into one of the C-See
software formats, it can be grabbed and
translated into many of the other formats. If
what you want is an inexpensive way to
handle digitized pictures, the Digisector
can't be beat.

Graphics du Jour

The Art Deli Library from Specialty
Projects is a compendium of PM0DE4 graph-

ics images that you can import into graph-
ics design or desktop publishing packages.
It comes in a package with a spiral-bound
book containing printouts of each of the
440 graphics images enclosed in the 10-
disk package. The images include every-
thing from animals, sports and holidays to
seasons, travel and more. A program on the
disks called SHOW loads each of the images
on a disk one after the other. There is no
documentation, however. It also has no
printer drivers. You can load a screen dump
program configured already for your printer
to accomplish this task. The more out-
standing feature of Art Deli is its ability to
transfer the images into desktop publishers
with file translation utilities or graphics de-
signs packages as clip art. The images are
categorized, high quality and professional.
(See Figure 3.)

There will be documentation included
in the next release of Art Deli, along with
the availability of a utility disk enabling
people to convert the Art Deli Library
images into other formats for incorporation
in desktop publishing documents. The
utility disk will sell for $14.95, and will be
available soon from Specialty Projects.
Specialty Projects has also released Art
Deli 11, which has 220 images on five disks.

You be the Judge

CoCo Graphics Designer Plus is a pro-
gram that makes banners, cards and signs
for 8 1/2-by-l 1-inch paper. It comes with
16 borders, five fonts and 32 pictures. There
are no word processing features and no
word wrap, but you can delete your mis-
takes readily enough. There is a preview
screen that gives an overview and allows
you to scroll around to specific areas.

It runs on any 64K CoCo or the CoCo 3
and requires a mouse or joystick. It is fast,
complete and has additional graphics, font
and special border disks available for $14.95.
You can convert the fonts and graphics into

a variety of formats for other desktop pub-

ent images per page and only as much text

and capabilities for moving, changing,
rearranging and so forth.

It has a good number of printer drivers,
and produces excellent documents. One
nice extra about CGDP is its built-in card
formatter to make cards in two different
layouts. The program can make a card

Art Deli

from Specialty Projects

What It Does: Art Deli consists of 440
pictures on 10 disks. It is a graphics
library with no internal programmed
capabilities.

Analysis: The images can be con-
verted to the appropriate format and
incorporated in a graphics program or
desktop publishing document.
Requirements: CoCo I, 2 or 3 and a
disk drive (is compatible with any
program that can translate binary,
PMDDE 4 or HSCREEN 2 or 3 files).
CoCoConclusions: Art Deli would be
a good investment for people who
make heavy use of high-quality graph-
ics designs in their desktop publishing
programs.

Pricing: $12.95 per disk or $99.95 for
a complete 10-disk set.

For more information, see the review
of Art-Deli in the October *87 RAIN-
BOW, Page 134.

paper several different ways to create a
greeting card. (See Figure 4.) While lim-
ited to two images per page, the images can
be stamped in three different sizes and
locations on the page, giving more flexibil-
ity. The documentation includes a brief
tutorial and is well written.

It supports almost all Radio Shack print-
ers, Panasonic, Star and NX1000 printers,
Epson and IBM.

Finding the Right Software

This has been a general overview of
what is available in CoCo desktop publish-
ing. It might be pointed out that one thing
missing from all but one (Newspaper Plus)
of the CoCo desktop publishing packages
is a driver for a laser printer. Laser printers
yield the highest speed, highest resolution
and highest quality print overall with the
least amount of noise. They are also quite
expensive. If, however, your business has a

DS69B Digisector

With C-See 3 3

from The Micro Works

What It Does: The DS69B Digisector
is a tool on a ROM pack for convert-
ing television pictures into a savable,
printable format.

Analysis: Pictures captured by the
DS69B can be converted into formats
that graphics and desktop publishing
programs can manipulate. In itself, it
is inexpensive, but it requires addi-
tional hardware that can be costly
Requirements: 64K CoCo 1, 2 or 3,
one disk drive, a Multi-Pak, video
camera or video source.
CoCoConclusions: This is a valuable,
full-featured enhancement to a desk-
top publishing or graphics design
software package. If you have the
necessary equipment, its low price
makes it a very good value.
Pricing: DS69B Digisector including
C-SeeJJ, $149.95.

laser printer, there is a good possibility that
it emulates one of the CoCo desktop pub-
lishing supported printers. In the descrip-
tion boxes you will find references to re-
view articles that have appeared in Rain-
bow for most of these products, a good
source for an in-depth look at these prod-
ucts.

What is most important in making your
selection is that you make it based on what
is right for your needs. Know what it is you
want, need and what you are gel l ing before
you spend those hard-earned dollars. There
are many programs out there for the CoCo
1 ,2 and 3 that will do great drawings or will
make fantastic fonts. But unless they meet
your needs, they are not what you should be
getting. Don't be wooed by what it does do,
ask what is missing. What is wrong with
this product? What doesn't it do that I need
it to do?

A program for generating fonts, a graph-

CoCo Graphics
Designer Plus
from Zebra Systems

What It Does: CoCo Graphics De-
signer Plus is an elegant program
designed solely for the creation of
signs, cards and banners.
Analysis: Although, it is good at what
it does, this program is not truly a
desktop publishing program. It is
supported by accessory font, picture
and border disks, which provide for
variety and flexibility.
Requirements: 64K CoCo 1, 2 or 3,
one disk drive, and mouse or joystick.
CoCo Conclusions: Co Co Graph ics
Designer Plus is a nice, fun, easy-to-
use program that does a good job on
signs, banners and cards. It has a card
formatter built in.

Pricing: CoCo Graphics Designer
Plus, $29.95; additional font, border
and picture disks, $14.95 each.

ics design program, a set of disks full of clip
art, a word processor — all have something
in common. Can you guess what it is?
Right, none of them are desktop publishers.
However, if you can take these elements
and combine them to create integrated text
and graphics, you've got desktop publish-
ing. Armed with some questions and some
knowledge as to what you need, you can
find a CoCo desktop publishing package
that is right for you.

As we evaluate and judge, we must
evaluate and judge ourselves. We are all
different and unique as people, and we all
have different needs. What desktop pub-
lishing package works for one, might not
work for another. What one can afford to
spend, another might not. At THE RAIN-
BOW, we can help with expertise and
experience, tell you of problems and pos-
sible solutions, and present the products
fairly for all to see and judge.

What It Does: These products work
as filters to create text files in many
different fonts, sizes and styles, with
hundreds of type styles to choose

Analysis: Although excellent at what
they do, these programs have no
inherent way to create graphics or
integrate them; they are text-only. It
is possible after creating a graphics
text file with OS-9 Calligrapher to
merge a graphics file into a text file,
but this would require outside soft-
ware.

Requirements: CoCo Calligrapher
requires a 64K RAM CoCo 1 , 2 or 3
(cassette or disk). OS~9 Calligrapher
requires at least one disk drive, 64K
and Level I or II OS-9.
CoCoConclusions: These are very
powerful tools for producing a wide
variety of fonts and typeset docu-
ments and is an excellent value.
Pricing: CoCo Calligrapher or OS-9
Calligrapher, $24.95; Font Sets,
$14.95 each; Economy Font Packages
with 25 to 30 fonts, $29.95 each; all
three Economy Font Packages pur-
chased as a set, $59.95; OS-9 Font
Massager, $19.95 or $14,95 with Cal-
ligrapher purchase.

By Edward Jones

How many times have you wanted to
set your printer for a particular
font or style, but didn't because
you hated to enter all those CHR$
codes? My program, Font Setter, was
written to make printer font selection
considerably easier. Although it was
designed for use with a CoCo 3 and the
Tandy DMP-130 printer, it can be
modified for the CoCo 2 and other
printers.

Edward W. Jones is a retired F.A.A. air
traffic control and radar operator who
lives in Mobile, Alabama.

On running Font Setter, it first re-
minds you to have your printer turned
on, followed by a menu that allows you
to select the font or style you want to
use. After you have chosen the combi-
nation of fonts or styles you want, press
R, and you will be asked if you would
like to print a test message. If your
response is yes, you may enter a message
of up to 255 characters.

Next you are asked if you want to
change any of the printer settings. If you
respond with 'Y\ you will be returned
to the main menu, where you can
change whatever needs changing. If you
respond with 'N\ the program ends and
your printer remains set for the style
you selected until it is turned off. I use
this program to alter my printer fonts
for LLISTs and other printing chores. 1
find the test message section handy for
writing short notes in selected fonts.

If you want to use this program with
a CoCo 2, change Line 20 so that it
contains only the CLS statement. Re-
move Line 220 completely. You can also
change all occurrences of CHR$ ( 21G ) to
"*" in lines 270 through 440, which will
then indicate menu selections with a star
rather than an ASCII color block. This
last change is not necessary for opera-
tion on the CoCo 2, but it makes the
screen look a little better.

In Line 20, POKE 150,18 sets the
computer to operate with the printer at
2400 baud. If you run your DMP-130
printer at 600 baud, remove this state-
ment.

Font Setter's menu does not allow for
all possible printer settings, but includes
those I find are used most often. If you
have a Tandy printer other than a
DMP-130, check your operator's man-
ual and change the CHR$ codes in lines
520 through 690 accordingly.

program may be directed to the author

DISK
CONTROLLER

We at OWL-WARE are
pleased to announce that we
have purchased the rights to all
of the Color Computer
Products of J&M Systems.
J&M has had more experience
with CoCo controllers than any
other supplier (except for
Radio Shack® itself) and we
are proud to add them to our
nest! OWL- WARE will now be
producing J&M controllers
under the OWL brand. These
controllers all use J&M's
proven designs, with some
minor improvements, and they
will serve you for years to come.

• All gold contacts

• Works with all CoCo
models (1,2,3)

• Holds 2 switchable ROMS

• Positive switching by
simple jumper or optional
external switch (No erratic
software or pokes re-
quired)

• Buffered I/O lines to help
prevent burn-out if unit
accidentally pulled out
with the system on

• Latching chips are sock-
eted to speed repairs

• Does not use the WD 1773
chip which caused
problems with many CoCo
3 systems and is now dis-
continued

• Attractive all metal case

• Dealer inquiries now in-
vited

Disk drives are not our only business, but they sure are our
main business! We have been selling hard and floppy drives for
the CoCo longer than any other Rainbow advertiser. Our double
sided drives are brand new, half-heights with a full one year
warranty! The full-height drives offered cheap by our competi-
tion are used or surplus!

CASE AND
POWER
SUPPLY

In recent months it has be-
come very difficult to obtain de-
pendable, safe power supply
and cases for floppy drive sys-
tems. They just couldn't pass
our quality control. OWL-
WARE has now produced a
case and power supply that you
can be proud to own and use.
We believe that this is the best
and most attractive drive case
available for any computer.

ture is unique in CoCo
drive cases)

On the Razor's Edge of

Basic and OS-9 Hard
Drive Systems

Proven Performance for Demanding Home or

Business Users

Every hard drive which has been
produced by OWL- WARE during the
last 3 years is complete. A system con-
sists of software, hard drive, controller,
heavy-duty power supply, and LR Tech
Interface. There are no hidden costs for
assembly or testing. When a drive sys-
tem is ordered, we fully assemble, test,
and burn-in the system for 3 full days.
This ensures dependability and op-
timum performance.

We have now been supplying CoCo
hard drive systems and parts for more
than 3 years. This is the longest history
in the CoCo market of any* system.
Some other advertisers are stating that
they have one of the most reliable sys-
tems for the CoCo with all of 4 months
history in the CoCo hard drive marketl
We have reached our position in the
hard drive market by providing our cus-
tomers with a quality product that they
(and we) can be proud to own and use.

Because of many requests for a lower
price system in kit form, we are now
selling a kit of all parts at a significant
discount compared to our regular
prices. We recommend this kit (or any
kits offered by any other supplier) only
to those who have experience in
electronic assembly and OS-9.

We have LR Tech and Burke & Burke

OWL Hard Drive BASIC 3

There have been several ads in this
magazine about BASIC for Color
Computer hard drive systems. These
ads sometimes only tell a part of the
story. Our BASIC system price in-
cludes assembly, testing, and 3-day
burn-in period. We do not require a
Multi-pak to operate.

Our hard drive systems are fast, reli-
able, and reasonable in price. This has
been proven by hundreds of users over
the past 3 years. We do not have to turn
off error checking for speed. We
achieve high speed BASIC from a uni-
que indexing method.

The table below will summarize some
of the key points about our BASIC hard
drive system and the B&B system. We
believe that we have the best BASIC in-
terface for CoCo hard drives available.

addition to the many beginner feature articles and programs

Hi-Res Screen Dump

By Shane Messer

CoCo 3

If you're like me, the first thing you think about when you
get a printer is graphics. However, the only screen dumps I've
seen are for the PMODE graphics, which turn out squashed —
and if you try to dump the 320/191 screen, it is about the
width of the page but the same height as the PMODE screen.
So I figured it out. If you take a 640/ 191 screen and dump
it sideways, it should take up most of the paper. If you have
a 320/ 191 screen and use the H5CREEN 4 command, it switches
your screen to 640/ 191 to dump it. This works fine; however,
when using the 640/ 191 screen, you must use Color 0 for the
foreground and Color 1 for the background. Once you type
in and run the program, it will draw a small design and print
it. It takes a while, so if you have a lot of draw statements
you can merge them into this program. I used a DMP-132
for this screen dump.

The Timer

By Wayne Hufford

This program is a timekeeper. It can be used for games or
any activity that has a time limit. At the first prompt, type
in how many minutes you want to count down, followed by
the number of seconds. There will be a one-second pause,
then the top of the screen shows the amount of time you
entered. Note: The time displayed is one second less than the
number you typed in because the one-second pause starts the
countdown. When the timer gets to zero, a low tone will
sound and the program will end.

BeamSD

By Joseph Pendell

Beam3D is a short program that allows you to animate
three-dimensional pictures. After you type in the program
and run it, a small box appears on the screen. Use the right
joystick to move it around. Press any key and the box
becomes fixed. The right joystick then moves a larger box.
Notice that the four corners of the two boxes are connected
to give the appearance of three dimensions. Press a key to
clear the screen and place the smaller box at a different
position. The variables Si and 52 in Line 10 are the sizes of
the two boxes, whereas lines 20 and 30 calculate a multiplying
factor. The product of a joystick reading and its factor give
a position on the screen. Multiplying factors are chosen so
that the boxes do not go off the screen. Lines 90 and 200 check
to see if the joystick has been moved since the last time it
was read. If it is the same, the graphics are not redrawn. Lines
140 to 160 do the actual drawing of the image. An easy
modification to the program is to change the box sizes in Line
10.

Hot Stuff

By Ric Pucella

This little game will keep you entertained for hours. It's
a version of a popular game many played when young, where
someone hides an object and others have to find it while the
"hider" clues the players by telling them they are either "hot"
— if they are close to the object's location — or "cold" —
if they are far from it.

In this game the "hider" is the computer and you must find
the object in a 30-by-30 square grid. (The size of the grid can
be changed by changing the value of D in Line 14 of the
listing.) To help you remember where you have looked, type
-1,0 at the prompt, and the computer will display all your
moves.

$Chores$ for Dollars

By Steve Paul

$Chores$ for Dollars is a handy program to inspire the
younger members of the family to help out with the daily
tasks around the home, $Chores$ is written in two sections.
Lines 2 through 8 handle the inputs while lines 10 through
15 print the chore list.

When you run $Chores$, the program asks for a list of
chores and their respective money amounts, allowing from
one to nine entries. When the list is complete, the program
automatically goes to the print mode in Line 6. $Chores$
prints two lists per page and as many pages as you want. Just
line up the printer ribbon with the top of the page and start
printing. It's amazing how ambitious my son became with
this approach to the chore problem.

Note Card

By Darrin Seats

Being a high-school English student, I have found how
unenjoyable giving speeches is. Making neatly-written note
cards for each speech simply adds to the misery. This program
prints a 3-by-5-inch note card by taking the information you
type in and dumping it to your printer. When the program
is done, cut out the note card along the dotted lines. Note
Card was written using a DMP-1 10; if you have a different
printer, just change the appropriate code in Line 150.

For many enthusiastic computer
users, understanding the mechanics of
their hardware is as essential as pen and
paper to a writer. The following article
will begin a basic explanation of the 40-
track disk drive. Articles to follow will
elaborate on various other drives.

First, to define a disk drive: A disk
is similar to a cassette tape and a drive
is like a cassette player. Both systems
use the principal of magnetism, and in
both cases the media is made of plastic
material coated on one or both sides
with a substance containing iron oxide.
This makes it sensitive to an electro-
magnet, called a head. Both cassette
players and disk drives have heads.

In a cassette player the tape is
dragged across the head by a motorized
mechanism. In the record mode, a
magnetic field is created by the record
electronics. This field varies in intensity
proportional to the signal it is record-
ing. The varying intensity leaves iron
particles in the tape aligned in a specific
order. Simply stated, the tape is magnet-
ized while in the record mode. Then the
tape dragging across the play head
makes tiny magnetic fields that are
transfered to electrical signals. These
are then amplified to an audible level.

A disk drive's electronics works much
the same way. The mechanism, ob-
viously, is different in that it is made
with a computer in mind. A cassette is
made for continuous music, which
makes it inconvenient when you want a
small piece of data at the end of a tape.
A disk drive, though, is made with the
ability to access any part of it quickly.

Let's take a closer look at a disk. It
is commonly known as a floppy disk,
because of its flexibility. The disk most
used by the GoCo community is Sc-
inch square and consists of four parts.

The first is the actual media. It is a
round piece of plastic, a little over 5
inches in diameter, with a IVfc-inch hole
in the center. Better-quality disks have
a second piece of plastic glued to the
inner side of the disk to reinforce the
mechanism that holds and spins the
disk. More on that later. It also has a
second hole, about 1/16 inch in diame-

and index pulses . . .

The
ABCs
of Disk
Drives

By Tony DiStefano

Rainbow Contributing Editor

ter, that is about a half-inch from the
edge of the inside hole. This is called the
index hole.

The third part of the disk is called the
jacket. The jacket serves two purposes.
First, it is a protective cover for the
media. Touching or bending the media
can damage it or completely destroy
data. Except for one slot, the jacket
completely covers the media. This slot
has to be left open so that the read/ write
head can access the media. The jacket
also has a hole on both sides to expose
the index hole and another hole to
expose that part of the media pinched
by the mechanism.

The second purpose is to protect the
media from being erased. In the upper
right-hand corner of the disk is a small
notch. When this notch is left uncov-
ered, the disk drive is able to write to
the disk whenever the software "tells" it
to. When it is covered with opaque tape
the disk drive cannot write to the media,
even if the software "tells" it to.

The fourth part of a disk is the sleeve,
a paper envelope that protects the
media from fingers or dust and cigarette
smoke. Most people don't realize it, but
cigarette smoke creates a thin film of tar

that attracts dust, putting extra wear on
the drive heads. Sleeves cover every-
thing from the index hole to the access
hole. Whenever a disk is not being used,
it should be stored in its sleeve. Never
leave a disk in a drive with the door
closed over a long period of time. It puts
a dent in the media.

Now let's discuss the drive. It is a
mechanism used to read and write data
to the disk. The first thing a drive does
is spin the disk inside the jacket. When
you close the door of a disk drive, a
plastic hub pinches the disk to the metal
hub and shaft of a motor. Older drives
had a capstan and were belt driven by
a separate motor. Now drives have the
motor built right into the hub. When the
drive is selected, the motor spins the
disk at about 300 rpm (revolutions per
minute), give or take 5 rpm. Older
drives took up to five seconds to come
up to speed; the newer drives can come
up to speed within two revs. That's
about two-fifths of a second.

The next responsibility of the drive is
to properly move the head. The read/
write head is mounted on a movable
assembly that can move across the
access hole in the disk jacket. The heads
rub on the moving media. Open the
door of a drive and peek in just after a
DIR and you will see the back-and-forth
motion. The assembly moves with the
help of a stepping motor. The head
movement is done in steps, with each
step being called a track.

With 40 of these tracks on each side
of its disk, the 360K drive is today's
most commonly used drive. The drive
is double-sided, meaning that there are
two read/ write heads, one for each side
of the disk. Tracks are numbered from
0 to 39, Track 0 being on the outermost
area of the disk and counting up as
tracks move toward the center. The
head can move back and forth on a pair
of rails controlled by a stepper motor
that receives one of two signals from the
controlling hardware.

The two signals are "step" and "direc-
tion." The direction is set according to
where the head is and where you want
it to go. Then the step pulse is applied,
and the head moves the distance of one
track in the specified direction. In the
case of the 360K drive, the distance
between two tracks is about one-forty-
eigth inch. That is 48 tracks per inch.

A hardware switch positioned to turn
on when the heads are at Track 0 tells

the controller where the head is. The
proper way to position the head to
Track 0 is to give the controller a restore
command or to step and test for the
switch until Track 0 is detected. Some
software steps in 40 times without
testing; but if the head is not at Track
40, then it bangs against the Track 0
stopper and can possibly become mis-
aligned. A register in the controller
keeps track of where the head is. If the
controller confuses where the heads are,
it restores to Track 0 and then steps to
the desired track.

Another duty of the drive is detecting
index pulse. The little hole in the disk
is used to give the controller a reference
point. Inside the drive on one side of the
hole is an IR (infra-red) LED. On the
other side there is an IR detector. When
the disk is spinning, most of the time the
light emitted by the LED is blocked by
the disk. Every revolution of the disk,
the hole appears in the path of the LED
and detector. This in turn gives a short
pulse to the controller. By this signal the
controller can determine a reference
point to the rotational position of the
disk.

This position reference is used when
formatting new disks. Formatting di-
vides the disk into small blocks called
sectors. Each sector has a unique ad-
dress or ID number. They are assigned
by track number, sector number and
side. Some controllers, however, do not
use side but, instead, have greater sector
numbers.

As mentioned earlier, tracks are
numbered 0 to 39. In CoCo's case,
sectors contain 256 bytes of data each.
There are 18 sectors per track per side.
Radio Shack DOS is written to handle
a single-sided drive with 35 tracks at 18
sectors per track. That gives you a total
of 256 bytes x 18 sectors x 35 tracks =
161,280 bytes per disk.

Since most drives today can step 40-
tracks and are double-sided. This is a
waste of data area. Some third-party
DOSs get around this by changing it to
handle double-sided and 40 tracks.

When formatting, the controller does
one complete track at a time. The index
pulse is used to start the writing head
up and then to shut it off. This keeps
the write head from writing over the
part already written on.

So far, I have been talking about the
mechanical parts of a disk drive, but
there is more — the electronics part.

A disk drive has several electronic
sections in it. Though the actual elec-
tronics varies, there are standard pro-
tocols that make drives made by differ-
ent companies compatible. This is
called the interface. All drives use a 34-
pin edge connector to transfer all elec-
tronic information to and from the
controller. All the pins do basically the
same thing. You can virtually unplug a
Panasonic 360K drive and plug in a
Tandem without any problems.Table 1
shows a pin list of the standard 360K
drive connector.

All odd pins are ground returns.
These signals completely control the
drive. The electronics needed for this
task are speed regulation for the spin-
ning of the drive, stepping the head in
and out, electronics to power the write
head and erase head, and amplifiers to
read the small signal of the read head
and to light the "drive in use" LED.

Now you should have a good idea of
how a disk drive works. Next time, I'll
discuss how an 80-track drive is differ-
ent and include a circuit on how to
double-step the drives so it can read
standard 40-track disks.

Machine Language Made BASIC

Part XI: 3-D Without Glasses

By William P.Nee

In last month's article about 2-D
rotation, everything was plotted
symmetrically and we didn't have to
pay any attention to location. Now we
will be discussing 3-D, and it becomes
more important to visualize where we
are actually plotting our points.

Think of the center of the screen as
0,0,0 — that is, zero x, zero j>, and zero
z. Numbers or bits to the right of the
center are +* and those to the left of the
center are -x. Numbers or bits above the
center are +_y and below the center are
-y Numbers or bits between you and the
screen are -z, and behind the screen are
+z. The z numbers or bits, of course, are
not really there, but they must be taken
into consideration when rotating
points. We still only PSET the x and y
coordinates.

Bill Nee bucked the "snowbird" trend
by retiring to Wisconsin from a banking
career in Florida. He spends the long,
cold winters writing programs for his
Co Co.

Since the Color Computer numbers
from the top of the screen down, we
change the y direction a little. Look at
the following diagram:

If you want to set a point (xl,yl) at
coordinates (+12, +16), what is the
actual screen location? Since the x\
location is to the right of the center, it's
location is 128+xl; since the >>1 location
is above the center, it's location is 96-
yl. The screen location is then 140,80.
If x2 is -20 and y2 is -30, its screen
location is 128+(-20),96-(-30), or
108,126. It is the x,y (and z) coordinates
that are stored and rotated, not the
screen locations.

In last month's article we actually
revolved points around the z axis al-
though we just called it rotating. Now
we need a formula to rotate around the
x axis, a horizontal line through the
center of the screen, and the y axis, a
vertical line through the center of the
screen. As before, x, y and z are the old
locations and xl 9 yl and zl are the new
rotated locations. (See Figure 1.)

Since we are using the same angle of
rotation in all three cases (see last
month's article), all three formulas are
the same — just the x, y and z are

different. Again, it is only the x and y
screen locations that are actually PSET.

The machine-language program
picks a set of 25 random coordinates
between 1 and 50 for x 9 y and z. Since
the pattern is symmetrical, there are
actually eight coordinate points com-
puted and rotated:

x,y,z x r y, -x,y,z -x,-y,z
x,y,-z x,-y r z -x,y r z -x,-y,-z

g an axis
f ? of rotation, the pro-
SB gram computes the
H other two coordinate's
; rotated position, but
the axis coordinate
remains unchanged."

Our coordinate table, which is two
bytes for each x 9 y 9 and z coordinate,
starts at $5200. The first x coordinate
is stored in locations $5200 +0, +6, +12
and +18; the negative x coordinate is
stored at $5200 +24, +30, +36 and +42.
The first y coordinate is stored at $5200
+2, +8, +26 and +32; the negative y
coordinate is stored at $5200 +14, +20,
+38 and +44. The first z coordinate is
stored at $5200 +4, +16, +28 and +40;
the negative z coordinate is stored at
$5200 +10, +22, +34 and +46.

So starting at $5200 we have: +jc, 0,
+y 9 0, +z, 0, +*, 0, +y 9 0, -z, 0, +*, 0, -
y 9 0, +z, 0, +*, 0, -y t 0, -z, 0, 0, +y 9
0, +z, 0, -, 0, +y 9 0,-z, 0, 0, -y, 0, +z,
0, 0, -y 9 0, -z, 0. The coordinate table
is then increased by 48 to get the start
of the next group at $5230. The amount
in NUMBER (FCB 25) is the number of
initial sets of coordinates, and eight
times this number is stored and plotted.
You can make the amount higher or
lower as you want.

Since we run the program from
BASIC, we do not need to set the PMODE
or color. After setting Page 5, the
computer randomly selects the axis of
rotation. Remember that $5200 is the
location of the first x coordinate, $5202

is the location of the first y coordinate,
and $5204 is the location of the first z
coordinate.

After picking an axis of rotation, the
program computes the other two coor-
dinate's rotated position, but the axis
coordinate remains unchanged. The
end of the program PSETS the x and y
screen locations. Pressing any key stops
the program and returns to BASIC.

Instead of using the machine lan-
guage program to pick the x 9 y and z
coordinates, you can use your own
program. The BASIC Alternate 3-D

/^^>omputer users have become ac-
( I customed to the timesaving lux-
V^^luries a computer provides — so
much so that many of us are driven mad
when we must wait for our printer to
finish before continuing to edit or
running the program. So I have made
a spooler using the 6809's IRQ and a
non-used 8K block of the CoCo 3.

The program works on any CoCo 3,
128 or 512K, and at any baud rate. Just
type the program BASIC in and save it
to a disk. Then run it and type EXEC
&HFC80. The program asks you for the
printer baud rate, after which the pro-
gram becomes transparent to BASIC.

When you make an LLIST with a
program under 8K, the screen shows
"OK" after two or three seconds and
then the cursor reappears while the
printer lists the program. Now you can
edit or run your program while printing.
If your program is longer than 8K — for
example, 13K — wait for the first 5K.

Marc Genois is a French-speaking
Canadian who studies Computer
Science in Quebec. He also operates a
french BBS in Quebec.

The cursor reappears and the last 8K is
buffered.

To stop printing, type EXEC. How-
ever, if you have loaded another ML
program, type EXEC &HFDQ7. Otherwise
you will execute the other ML program.

With my DMP-130 and a serial/
parallel interface at 9600 baud, there is
no speed difference in the BASIC and the
printer going at the same speed as a
normal LLIST. In fact, I have tested it
at all baud rates and at 1200 bps or
faster I see no difference. At 600 baud
BASIC runs a bit slower, but the key-
board response is good. Occasionally at
300 bps BASIC does not get the key you
have pressed.

The program uses none of BASIC
memory and is located in a lost space
after the new BASIC A fairly expe-
rienced assembly programmer can put
it after the RS-DOS (at $D8DO) and
burn it on EPROM. But I have not
located it after the DOS for compatibil-
ity with other DOSs that use this space.

May 1989 THE RAINBOW 87

1 B AS I C Training

This article employs various atti-
tudes used during the last lesson
in which we created the figure of
a bird. The following instructions will
allow you to run this bird through some
simple flight and behavior patterns and
will provide you a foundation upon
which to create more complex patterns.

The graph-paper utility is not needed
since we have developed enough raw
material to illustrate additional anima-
tion techniques. Refer to Listing 1.
Lines 0 to 290 are very similar to last
month's program. If you saved it, load
it and enter DEL300-.

Line 1 10 is different. It has the second
screen, SCREEN 1, and PCLS because all
six attitudes were unveiled for refer-
ence. This is the reason Line 290 is
masked.

If you did not save the program,
simply key in lines 0 to 290 from Listing
1. Enter 1B1 GOTO 181, then run the
program. You can see the six attitudes;
from left to right, the variable names are
fl, 8, C, D, RR and BB.

In assigning variables, try using a
sequence that is easy to remember. Here
is a list of my attitudes and correspond-
ing variables:

Wing up attitudes R&B

Wings down C&D

Wings partly up RR

Wings partly down BB

With these you can make a tentative
flight plan. My strategy for returning to
the up-wing position is to use C, a
variant of D, to give a different time-
lapse impression. To move the head up,
BB continues the impression, followed
by RR, passing the horizontal plane in an
upward direction and ending in the full
up-wing position using B. Use any
position or sequence you like. Be crea-
tive. You should have no trouble rough-
ing out a variety of possible attitudes on
graph paper. Here is a possible config-
uration:

BDM+3, -2M+3 , -2M+3 , -2M+3,2

A straight-line horizontal plane atti-
tude was not created because although
the bird travels through the horizontal

plane on each flap, a straight line would
be too distracting.

Enter DEL1B1, then key in lines 300
and 320 to 430. Attitude R is located
from (12,12) to (2, 4, IB). Key in Line
320. In the same location, replace R with

RR.

To make this transformation less
abrupt, put a pause between the atti-
tudes. Key in Line 310. (We're using a
G05UB routine because we will use it
several times.) Note PCLS0. Add 325
GDTD 325. Type EDIT430, then press
ENTER. Press the space bar until the
cursor is under P. Enter GD to delete
PCLS0, then run the program. Then type
DEL325, but don't run the program.

Our next pair of flaps are in lines 340
and 360 so key them in. They move to
the right, +6 and down, +6. Enter 345
GOTO 345, then run the program. Notice
that R vanished but not RR. To correct
things enter EDIT430 and press ENTER.
Then press the space bar until the cursor
is under R. Type I (for Insert) PCL50 :
and press enter.

Key in lines 330 and 440. To make the
pause longer in duration, we added a
shorter pause. An example is the short
pause between flaps at Line 310 and the
longer pause while moving to a new
location at Line 330. Now run the
program.

As soon as the bird location changes,
our reference group of attitudes is
erased, as well as the bird, RR, at the old
location. Do you know what erased fl?

Mask Line 310. You are asked how

CoCo erases the lines in this situation.
Lines 300 and 320 (with pause and erase
masked) erased fl. R and RR are in the
same location, as were all the PUTS in the
last tutorial. Each new PUT prints a new
frame over the previous one, destroying
it.

Unmask Line 310. Enter DEL345 and
key in lines 350 and 370, the short and
longer pauses.

Key in lines 380 to 410. Note that we
move each pair of frames, C, BB and RR,
B, (+6,+6).

If you want to save the program,
enter CSAVE. Experiment by substituting
your home-grown bird attitudes and by
changing locations. This is a good time
to take a breather and go over what
you've read so far.

To continue, look at Listing 2. If you
saved your copy of Listing 1, load it by
entering CLQRD, then type DEL420- and
key in lines 420 to 510. Carefully com-
pare lines 300 to 410 and change the
GQTQs and GOSUBs to reflect those in
Listing 2. Then run the program.

We are creating different flight pat-
terns, but they aren't logical. Our prime
purpose is to continue exploring how to
locate various attitudes.

You recall that in lines 300 to 410 the
bird was at one location in a pair of
attitudes before moving to the next
location. His flight downwards is not
the same as his return trip. Press BREAK
and enter LIST-4B0. The six attitudes
return it to its original position. They
are, in order, RR, BB, C, D, BB, RR. There
is no change in the sequence of pauses:
a short pause, a long pause and repeat
sequence.

Here is how lines 430 to 480 are
actually set up: The chosen attitudes are
selected and listed on scratch paper. The
coordinates in Line 410 are noted and
written down. The first of the six lines
is 430, and its variable was added to the
coordinates pulled from Line 410. On
the work paper copy it looks like this:

430 (30,30) - [42,36) ,RR

The coordinates from Line 300 are
written about two inches below. The
sixth line is designated as Line 480, and
its preassigned attitude is RR. It looks
like this:

4B0 (12,12)-(24,18) , RR

Line 480 is printed over the attitude
in Line 410 to avoid jerky motion in

88 THE RAINBOW May 1989

flight. Line 480 should be printed at the
same location as Line 300. This blends
the movement of frames.

On the work-sheet, between the start-
ing and ending move, write in:

440 ( )-( ),BB

450 ( )-( ),C

4G0 ( )-( ),D

470 ( )-( ),BB

All you need now are some coordi-
nates in the four lines. Each line's
starting coordinates are the most im-
portant. The ending coordinates are
predicated on the starting ones,
(+12,+6).

I decided to use coordinates (24,24)
in lines 440 and 450; (18,18) in lines 460
and 470. These figures are written on the
worksheet. It doesn't take a genius to
add +12,+6 to each to get the ending
locations of each frame.

Even though we are working upwards
and to the left, our ending locations are
always higher figures than the starting
coordinates. Think of it as hanging a
canvas in a location of your choice that
is set with the beginning coordinates.
The actual picture takes up the area that
is defined by the ending coordinates.

Fill them in on your work-sheet. You
know how to make PUT lines. At this
point, it is pretty much a copying chore
to transfer the data you accumulate into
the program to create a flying loop. Line
4,80 also has the instructions to loop
back to Line 300. Modify anything you
feel could be improved to create other
flight plans.

We use a somewhat different method
in Listing 3. Load your copy of Listing
2 and enter DEL300-. In Line 110, chop
off Screen 1,1. We don't want the
attitudes created and stored by unmask-
ing Line 290 to remove them from the
screen. Key in lines 300 to 460 and run
the program.

The bird cycles across the screen a few
times, first downward and upwards
without seeming to change direction,
then undulating as it advances from left
to right. (In this tutorial, x,y are the
horizontal and vertical coordinates
respectively.) Line 300 allows CoCo to
begin its flight path at a location ran-
domly chosen from 0,60 to 0,120.

Begin a worksheet by listing the
scoop on the first line. For example:

320 (X,Y)-(X+12,Y+G).

Our attitudes will probably change
until we get a smooth movement plot-
ted. Expect to make eight frames in a
downward direction and about six
frames for wavy lines, 14 frames to a
cycle.

Add on your paper places for lines
330 to 460:

330 (X+, Y+)-(X+, Y+)

tt tt tt tt

460 (X+, Y+)-(X+, Y+)

In the first eight lines on your work-
sheet, you will progress by in-place
pairs, creating the starting location,
(+6,+6). The ending locations will be
increased by (+12,+6). As a result, lines
320 and 330 are the same. The starting
locations for Line 330 are y+0 or
x,y.

Add +6,+6 to lines 340 and 350, then
enter the info on the worksheet. Con-
tinue the same increment pattern for
lines 360 and 370 to begin at
(x+12,y+12). Guess what the starting
coordinates are for lines 380 and 390?

All the ending coordinates are + 1 2, +6
more than the starting coordinates.

May 1989 THE RAINBOW 89

Calculate them and enter them in the
appropriate places on the worksheet.

Line 400 is a masked reference line to
indicate that the system is changed and
we are preparing to move up and to the
right. Therefore, cross out Line 400 on
your worksheet.

In order to give an uneven aspect to
the flight, the attitudes used in lines 410
to 460 are not paired.

Look at lines 410 to 460. The x
forward motion increases by +6 each
time, y decreases by -6 except in Line
440.

Line 410 takes a quantum drop at
+6,+ 18. This simulates a sudden drop in
an air pocket to add a glitch to the flight
track. Note Line 440. It wasn't moved
on the vertical coordinate, giving it a
more erratic flight. Copy these offsets
and then calculate and enter the ending
coordinates, based on the beginning
coordinates.

Now variables are chosen and as-
signed to each PUT line to make a viable
flight.

Gather the info and key in one pro-
gram line at a time, without the GOSUB
routines and yanking PCL50: out of
Line 500, to see how the pattern shapes
up. This is of limited value. You see
where the frames progress but the proof
is in the pudding — that is, how it looks
in flight. Since you are also manipulat-
ing locations and time pauses, the
interplay of attitude, location and pause
has significant visual effects.

After you finalize your choice of
attitudes and enter the PUTS, add

multiple-line gosub pause routines, etc.
Ultimately you must use trial and error
to wind up with your desired effect.

A FOR/NEXT loop at Line 310 to 470
allows the flight curve to run across the
screen four times.

Line 480 gives a hint of the bird as it
flies off the screen. Note that X+259 did
not bomb out the program. What value
would? Try X+969. You can even change
the value to X+G5000 and C0C0 will still
cooperate.

Line 480 is really a nonsense line. The
last frame set by Line 460 PUTs x at 240.
AT equals (240+247). The value in Line
480 equals 487. The only thing that
saves it is that y is a good value. C0C0
sets the y and gives up on frame, if you
are quick enough. Press break and
enter PRINT X,Y. Then run the program.

If you use 4B0 PUT (247, Y)-

(259,Y+6), B, P5ET, you get a traffic
jam at the right edge. C0C0 can't find
a place to put the frame because the
ending coordinates are off the screen, so
it dutifully backs up and tries to get it
all on. The result is one big mess.

One of the hazards of using GET-PUT
is a bunched-up or junk frame. This
malfunction is caused by off-the-screen
location or DIN not allowing storage of
the full canvas. But more frequently,
improper calculations result in a PUT
area that is not the same as the GET area.
This error resides in the ending coordi-
nates.

The coordinates to give the closest
full picture without a pile-up are
(243,Y)-(255,Y+16). The bird looks

like it is flying across the screen but is
really flying sideways. Now make a
copy of your final program.

The conventional way to show a bit
of bird would be to DRRW one wing in a
6-by-6 area, enter DIN and GET, then
enter PUT at the edge of the screen at 249.

Add to Line 120:

,CC(2)

1B1 DRAW"BN120,OBDGN+3,-2E2N+l,2"

(a wing with a bend.)

2B1 GET (120,0) - (126,6) , CC,G
480 PUT(29,Y)-(255,Y+6) , CC,
P5ET:GOSUB510:GDTQ300.

Then run the program.

You may use the (x,y) system to begin
at any location as long as you designate
the values of x and y in the program PUT
line:

DEL300-

300 X=50;Y=50

310 PUT (X,Y)-(X+12,Y+6) ,C,P5ET
320 PUT (X-10,Y-10)-(X+2,Y-4) ,D,
P5ET

330 GOTO 330

Then run the program.
Line 320 translates to:

PUT (50-10, 50-10)-(50+2, 50-4)
Or PUT (40,40)-(52,46)

Hope this gives you food for thought
and an itch to try your hand at anima-
tion. □

If you have an idea for the "Wishing
Well/' submit it to Fred c/o THE
RAINBOW. Remember, keep your
ideas specific, and don't forget this is
BASIC. All programs resulting from
your wishes are for your use, but
remain the property of the author.

Let me tell you, it's no easy task
coming up with a new program every
month of the yean Strangely enough,
inspiration always finds its way to my
door. While agonizing over what to
write this month, someone suggested a
program about the twelve months of the
year.

Lo and behold, Calendar was born.
Now there's an early childhood pro-
gram to help students learn the order,
names and climates of each month. So
you see, "twelve months" solved the
problem for one.

Since first introducing the programs
Opposites and Count on Me, I have
received very positive responses to
early-childhood educational programs
for the CoCo. When many families buy
a Color Computer, "having it help the
kids" is a good justification for the
money spent. But it is often hard to
fulfill due to the lack of good youngster-
oriented software. Calendar is one step
in the right direction.

This program is designed to use the
same basic format as introduced in
Opposites and Count on Me, with a
graphics representation for each month.
This is a good starting point — famil-
iarizing the child with the order of the
months and an illustration to associate
with each one. (For example, a snow-
man for January, a Valentine for Feb-
ruary, etc. . . .)

Next, the program asks questions
about each month. By pressing the
space bar, the user can advance to the
correct response and then press ENTER,
allowing the program to continue ask-
ing questions. If the response is correct,
the screen shows the correct match. If
incorrect, the screen flashes and the
student is given a chance to try again.

Fred Seer bo is a special needs instructor
for the North Adams Public Schools in
North Adams, Massachusetts. He holds
a master's in education and has pub-
lished some of the first software avail-
able for the Color Computer through
his software firm, Illustrated Memory
Banks.

Learning the order, name
and climate of each
month

Twelve
Months
of Fun

By Fred B. Scerbo

Rainbow Contributing Editor

A scorecard may be seen by pressing the
@ key. Pressing C from the scorecard
will allow you to continue with the quiz.

The written quiz section asks ques-
tions like, "Which month comes be-
tween January and March?" This helps
train and quiz students on the order of
the months. The information, though
quite basic, is essential to all young
children and this is a new and fun way
of learning it. In addition, it works to
familiarize the child with the computer,
laying a good foundation for using
more advanced programs as the child
gets older.

The graphics are drawn in bold black
and white since many beginners use a
black and white television with their
first CoCo. Be careful when typing in
the listing, which can be very long
because of the graphic strings involved.
(In the past I have shown you ways to
merge these graphics to Match Game,
but this program uses more strings to
draw the pictures. I need to come up
with a few more changes before I can
give you alterations for using that
program with these pictures.)

I hope all of you have someone in
your family or among your friends who
can benefit from Calendar.

Thanks to the many people who have
continued to send old gray CoCos for
us to distribute in our special needs
classes throughout our school system. I
am expecting our local news media to
run some coverage on these new com-
puter stations, which were donated
from my many kind readers. If I can
reprint anything from those articles, or
any pictures, I will try to do so.

We do have several donated disk
drives with no controllers. If any of you
have an old controller that is collecting
dust and you would like to donate it,
you may contact me in care of Drury
Senior High School, S. Church St.,
North Adams, MA 01247. The same
goes for any older graphics Adventures
you have solved and for which you have
no further use. (Please, no pirated
copies. That only hurts those of us who
are trying to help create new software
for you!)

Until next month, good luck in your
CoCo dealings! □

BAS I Ca ll y Sp e aking

Editor's Note: This issue marks Larry
Boeldt's solo debut as editor of rain-
bow's "BASICally Speaking" column,
an assignment handed over to him by
the rainbow and an extremely busy Bill
Bernico. As previously, "BASICally
Speaking" will continue to address and
solve your programming problems.

Dear Larry:

I'm an amateur radio operator and
have been the proud owner of a Co Co
3 for the past five months. I would like
to know if the CoCo 3 is capable of
receiving international Morse code
through some means of decoder circuit
and print text on the screen. What ports
would I have to use, and how would the
sofware be written?

Dwayne Fitzgerald
Wilson 's Beach, New Brunswick

Dear Dwayne:

To my knowledge there is no such
device for the Color Computer. You
might try to contact a hardware pro-
ducer or even Tandy to find out if such
a product is available.

Dear Larry:

Is there an easy way to change graph-
ics statements like LINE, DRRW and
CIRCLE in a Co Co 2 program to HLINE,
HDRRW and HCIRCLE statements on the
Co Co 3?

Danna Aschenbach
Rock Springs, Wyoming

Dear Danna:

This could not be more timely. You
can convert the program in this column
[See the following letter.] that changes
PRINT statements to PRlNTtt-2, state-
ments to work for graphics commands
as well. The graphics, of course, would
only show up on the left portion of the
screen, but it saves a lot of typing. The
same rules apply for the graphics con-
versions. Don't forget to save the pro-
gram in the ASCII format.

Larry Boeldt has five years of expe-
rience on the Color Computer and owns
a CoCo-based company geared toward
customizing software for businesses.

Speaking

By Larry Boeldt

Just change the lines in the program
as follows:

72 INPUT"ENTER THE COLOR COMPUTE

R 2 C0MMRND;"C2$

220 0F=IN5TR(0F,R$,C2$)

240 fi$=LEFT$ ( fi$ , OF-1 ) +"H"+RIGHT$

( R$ , L5- OF ) : 0F=0F+LEN ( C2$ )

Don't forget that you must select the
proper HSCREEN before the graphics are
drawn. You must run this program for
each command you want to convert. It
saves a lot of time compared to search-
ing for each command individually.

Dear Larry:

There is a program in the February
1983 RAINBOW that converts PRINT
statements to PRINT a -2, statements. I
am having trouble using this program
on a disk system. Could you convert the
program to work on a Co Co with disk?

Earl Jesse Foster
Lynchburg, Virginia

Dear Earl:

According to the program's writer,
the program should work fine on a disk
system — except for the CSflVEM com-
mand, which should be replaced with a
SflVEM command.

Here is a program written in basic
that will do the same thing. As with both

programs, the assumption is made that
each line of a BASIC program contains
no more than 240 characters. To be
converted the program must be saved in
the ASCII format SAVE" filename ",fi.

The

7HE COLOR COMPUTER MONTHLY MAGAZINE

THE RAINBOW is the biggest, best, brightest and
most comprehensive publication a happy CoCo
ever had! THE RAINBOW features more programs,
more information and more in-depth treatment of
the Tandy Color Computer than any other source.

A monthly issue contains nearly 200 pages and
up to two dozen programs, 14 regular columns and
as many as 12 new product reviews. And advertise-
ments: THE RAINBOW is known as the medium for
advertisers — which means every month it has a
wealth of information unavailable anywhere else
about new products! Hundreds of programs are
advertised in its pages each month.

Every single issue of THE RAINBOW covers the
wide spectrum of interests in the Tandy Color
Computer — from beginners' tutorials and arcade
games to telecommunications and business and
finance programs. Helpful utilities and do-it-
yourself hardware projects make it easy and fun to
expand your CoCo's capabilities. And, monthly
reviews by independent reader reviewers take the
guesswork out of buying new software and hard-
ware products.

Join the tens of thousands who have found THE
RAINBOW to be an absolute necessity for their
CoCo. With all this going for it, is it surprising that
more than 90 percent of THE RAINBOW subscrib-
ers renew their subscriptions? We're willing to bet
that, a year from now, you'll be doing the same.

Rainbow On Tape

& Rainbow On Disk!

— great ways to bring THE RAINBOW into your life.
Each month, all you do is pop the tape into your
cassette player or the disk into your drive. No more
lost weekends. As soon as you read an article about
a program in THE RAINBOW, it's ready to load and
run. No work. No wait.

Just think how your software library will grow.
With your first year's subscription, you'll get almost
250 new programs: games, utilities, business
programs, home applications. And, with RAINBOW
ON DISK, you'll also get all the OS-9 programs.

RAINBOW ON TAPE and RAINBOW ON DISK —
they're the "meat" of THE RAINBOW at a price that's
"small potatoes." And now you even have a choice
about how it should be served up to you.

To get your first heaping helping, just fill out and
return the attached reply card. No postage neces-
sary.

Pyramix

This fascinating CoCo 3 game continues
to be one of our best sellers. Pyramix is
100% machine language written
exclusively to take advantage of all the
power in your 128K CoCo 3. The Colors
are brilliant, the graphics sharp, the
action fast. Written by Jordan Tsvetkoff

The Freedom Series

Vocal Freedom

I've got to admit, this is one nifty
computer program. Vocal Freedom turns
your computer into a digital voice
recorder. The optioaal Hackir's Pat lets
you incorporate voices or sounds that you
record into your own BASIC or ML
programs. This is not a synthesizer.
Sounds are digitized directly into
computer memory so that voices or
sound effects sound very natural. One
"off-the-shelf" application for Vocal
Freedom is an automatic message minder.
Record a message for your family into
memory. Set Vocal Freedom on
automatic. When Vocal Freedom "hears"
any noise in the room, it plays the pre-
recorded message! Disk operations are
supported. VF also tests memory to take
advantage of from 64K up to a full
512K. Requires low cost amplifier (KS
cat. *277-1008) and any microphone.

Mental Freedom

Would your friends be impressed if your
computer could read their minds? Mental
Freedom uses the techniques of
Biofeedback to control video game action
on the screen .Telekinesis? Yes. you
control the action with your thoughts and
emotions. And, oh yes. it talks in a
perfectly natural voice without using a

speech synthesizer! Requires Radio
Shack's low cost Biofeedback monitor,
Cat. «63-675.

BASIC Freedom

Do you ever type in BASIC programs,
manually? If you do. you know it can
be a real chore. Basic Freedom changes
all that. It gives you a full screen editor
just like a word processor, but for
BASIC programs. Once loaded in, it is
always on-line. It hides invisibly until
you call it forth with a single keypress!
This program is a must for programers
or anyone who types in programs. By
Chris Babcock and a product of
ColorVenture.

Lightning Series

These three utilities give real power to
your CoCo 3.

Ram disk Lightning

This is the best Ramdisk available, It
lets you have up to 4 mechanical disk
drives and 2 Ram drives on-line and is
fully compatible with our printer spooler

below.

Printer Lightning

High capacity print spooler for CoCo 3.

Load it and forget it- -except for the
versatility it gives you. Never wait for
your printer again! Printer runs at high
speed while you continue to work at the
keyboard! Will operate with any printer
you have already hooked to your CoCo.

Backup Lightning

This utility requires 512K. Reads your
master disk once and then makes
superfast multiple disk backups on all
your drives! No need to format blank
disks first! Supports 35. 40 or 80 track
drives.

COCO Bra Me

Produce standard grade 2 Braille on a
Brother daisy wheel printer. Easy to use
for sighted or blind user. No knowledge
of Braille is necessary. Call for free
sample. The raised dots produced are
easily touch readable by the blind. The
print-to-braille algorithm is robust with

errors rarely being made — and. it has the
ability to learn!

High-density printer enhancements for
the shoestring desktop publisher

High Capacity
Screen Dumps

for the Shoestring
Desktop Publisher, Part I

By H. Allen Curtis

^ ver since "A Desktop Publisher
^ on a Shoestring" appeared in
^THE rainbow (October '87 Page

58), I have been continually striving to
upgrade, improve and enhance the
original shoestring desktop publisher

programs.

The quality of any desktop publisher
is reflected directly and crucially with
the quality of its screen dumps. The
purpose of this article is to present high-
quality, high-capacity screen dumps
that maximize the capabilities of print-
ers most commonly used by CoCo
owners. Let me assure those who own
screen dumps that those presented here
are meant to augment rather than to
replace them.

The screen dumps formerly devel-
oped to work with Desktop Low (DESK-
TOP!.) and Desktop High (DESKTDPH),
the desktop publisher programs for the
CoCos 1 , 2 and 3, print two screens-per-
page. The new screen dumps dramati-
cally increase the screen-per-page ca-
pacity to six, eight and 12 screen dump
prints at a dot density of 240 dots-per-
inch. This density approaches the 300

Virginia. He is interested in 17th and
I8th century history and enjoys biking

ces past and present with his computer
work.

dots-per-inch capabilities of most laser
printers. The six- and eight-screens-per-
page screen dumps produce two-
column printouts with three and four
screen dumps per column. The 12-
screens-per-page screen dumps yield
three-column printouts with four
screens per column.

The low-capacity, two-screens-per-
page screen dumps, especially for DESK-
TDPL often require the use of the
smaller-sized fonts because of the print-
out magnification. The high-capacity
screen dumps condense the character
printout size and thereby significantly
increase the versatility and flexibility of
the shoestring desktop publisher in the
utilization of a wide variety of fonts.

The high-capacity screen dumps re-
quire more time to print per page.
However, the printout time per screen
is reduced considerably. Thus, the new
screen dumps are also time savers.

These screen dumps were also de-
signed to act primarily in conjunction
with the word processor input file
feature introduced in "The Desktop
Publisher: A Reprise" (September '88,
Page 102). Nevertheless, they can be
employed, but with less convenience
without that feature.

There are eight different high capac-
ity screen dumps presented here. Half of
them were written to work with the
Tandy DMP series of dot-matrix print-
ers. From my correspondence with
shoestring desktop publisher users, it
appears that most have DMP- 105 and
-106 printers, the least expensive of the
DMP printers but with of the greatest
graphics capabilities. All four screen
dumps meant for DMP printers can be
employed to their utmost with the
DMP-105 and -106 printers.

Closely following in graphics capabil-
ities are the DMP-1 10 and -200 printers,
which can be used with all four of the
screen dumps and with three of them to
their utmost. The DMP printers with
the least graphics capabilities are the
100, 130 and 130 A, able to be employed
with only one of the four screen dumps.
Screen dumps ordinarily print eight
screens per page, but with those three
printers it is limited to six. Owners of
DMP-130 and -130A printers should
note that with a parallel-to-serial-
interface connection the two printers

1 00 THE RAINBOW May 1 989

can emulate IBM printers. Under this
emulation the other four high-capacity
screen dumps can be used by the DMP-
130 and -130 A printers.

Four screen dumps were designed to
work with Epson printers and the com-
monly used Epson-compatible printers.
All printers used with the screen dumps
SCRNDMP and SCRNDMPS of "Screen
Dump Extraordinaire" (October '87,
Page 30) are Epson-compatible insofar
as their graphics capabilities are con-
cerned.

For desktopl there are two BASIC
driver programs, each servicing two
high-capacity screen dumps, one for
DMP printers, the other for Epson
compatible printers. There are also two
BASIC driver programs with similar
functions for DE5KTDPH. Both DESKTOPL
and desktqph will be modified to give
their O commands a high-capacity
screen dump option.

After the screens — six, eight or 12
— intended for a printed page are
generated and saved, the high-capacity
screen dump option of the O command
should be chosen. This causes the auto-
matic loading and running of the ap-
propriate BASIC driver program. After
the driver-initiated printout is com-
pleted, the driver optionally allows
another printout, program termination,
or an automatic loading and running of

DESKTOPL or DESKTQPH.

Desktop Low Printouts

The BASIC printer drivers used in
conjunction with DESKTOPL are shown in
listings 1 and 2. DRIVERLT, the program
of Listing 1, is the driver for DESKTOPL
and Tandy DMP printers. Likewise,
DRIVERLE, the program of Listing 2, is
the driver for DESKTOPL and Epson-
compatible printers.

DESKTOPL must be altered to work
with DRIVERLT or DRIVERLE by merging
to it one of four patch programs, LAL-

TER, LALTERD, LALTERE and LALtERDE, of

listings 3, 4, 5 and 6 respectively. Which
patch program to merge with DESKTOPL
depends on the version of the program
used. Presently there are effectively four
versions of DESKTOPL, which are an
outgrowth of selling many DESKTOPL
users built-in screen dumps, enhance-
ments or both.

Table 1 shows with which version of
DESKTOPL each program of listings 3 to
6 is associated. Any of the four effective
versions of DESKTOPL may or may not
include the word processor input file
feature. Moreover, these four versions
may accommodate two, 10 or 19 fonts,
depending on whether additional fonts

were purchased. If you use the version
of DESKTQPH published in RAINBOW use
the LALTER patch file from Listing 3.

Each patch program gives the O
command of desktopl the ability to
transfer control to DRIVERLT or DRIVE-
RLE. Those with Epson-compatible
printers need to change Line 645 of the
patch program associated with their
version of DESKTOPL by replacing

DRIVERLT with DRIVERLE.

The powers of the O command are
expanded further by each patch pro-
gram. It adds an option to the O com-
mand allowing you to look at the direc-
tory of the disk in Drive O. For later
printing, you can save six, eight or 12
screens on disk by means of the O
command using the save screen option.
To keep track of files already on disk
you can occasionally use the directory
option of the O command. If you have
more than one drive and have fonts,
DESKTOPL has the ability to address
drives when saving screens. You may in
such a case save screen files on a disk
in a drive other than Drive O. You
should then append to DIR in Line 645
a drive number one, two or three cor-
responding to the drive used.

When the patch program for DESK-
TOPL version is typed, if you have made
any changes in Line 645, save it in
ASCII form. If you choose to save
LALTERD, for instance, in ASCII form,
type save "LALTERD", A and press

ENTER.

To alter DESKTOPL, do the following:
Get out the disk containing DESKTOPL
and its font files; Make a backup copy
of the disk; and put away the original
and work with the backup copy. For
compatibility with DRIVERLT or DRIVE-
RLE, DESKTOPL must have the filename
DL.

Therefore, insert DESKTOPL in the disk
drive and type: RENAME "DESKTOPL'
BAS"T0"DL/BA5" and press ENTER.
Next, type L0AD"DL" and press ENTER.
Then, insert the disk containing patch

program LALTER, LALTERD, LALTERE, or

LALTERDE. If the program is LALTERDE,

VAxy.-:-

for example, then type: merge" LAL-
TERDE" and press enter.

You would do similarly for any one
of the other three patch programs but
with its name instead of LALTERDE.
Finally, insert the disk containing DL in
your drive and type 5AVE"DL" and press
enter.

Depending on the printer, you may
need to change some lines of the driver
program DRIVERLT or DRIVERLE. The
poke command in Line 5 of each of
these programs is employed to set the
baud rate of each particular printer. If
the printer operates at 600 baud, you
don't need to change Line 5. Otherwise,
delete the apostrophe from Line 5 and
replace the question mark with the
value associated with the baud rate of
your printer.

Baud Rate

Value

1200

2400

4800

6 or 7

9600

If you have a DMP-110 or -200
printer, change lines 720 and 740 of
DRIVERLT to include "elongation on"
and "elongation off" printer control
codes. In particular, replace CHR$(19)
with CHR$(14) in Line 720. Also insert,
CHR$(27);CHR$(15) between 2 and : in
Line 740.

Line 680 was written for the 800 dots-
per-line graphics mode of the DMP-105
and -106 printers. If your printer has a
960 dots-per-line graphics mode, delete
Line 680.

If you have a printer that is Epson-
compatible but is not an Epson, you
may need to tailor DRIVERLE to fit the
needs of your printer. The tailor-
making process, though somewhat
tedious, is well worth the effort.

It involves changing eight DATA state-
ments containing Epson printer control
code sequences. Lines 570 through 600
contain the control codes for a two-
column printout. Similarly, lines 650
through 680 hold the control codes
needed for a three-column printout.

Table 1

May 1989 THE RAINBOW 101

The first DfiTfi value in each of the lines
specifies the number of values in the
control code sequence represented by
the remainder of the DfiTR statement.
Lines 570 and 650 are identical and
specify the control code sequence for
line spacing.

For ordinary printing, the printer
provides a line spacing of 1 / 6 inch that
produces six lines of print per inch. For
the printer graphics modes, the line
spacing must be a closer 7/72 inch. The
Epson control code sequence that yields
the required line spacing is 2, 27, 49. In
lines 570 and 650 the initial value of 2
indicates that the following two values
27 and 49 represent the control code
sequence. Check your printer manual to
see whether or not 27, 49 is the control
code sequence for a line spacing of 7/
72 inch. If not, modify lines 570 and 650
accordingly. If it has three values, for
instance, in addition to changing the
control code sequence, you need to alter
the initial value to 3. In such a case the
DflTR statement ends with four 0 values
instead of five required for the Epson
printer.

Your printer may automatically ad-
just the line spacing to fit the graphics
modes, wherein you just need to replace
the initial value 2 in lines 570 and 650
with 0. However, if your printer does
not have automatic line spacing adjust-
ment and you make the 0 for 2 substi-
tution, your printout will show notice-
able gaps between lines.

BASIC lines 600 and 680 also deal with
line spacing, holding control code
sequences for the return to 1 / 6 inch line
spacing. Therefore, check the manual
for a 27, 50 control code sequence, and,
if needed, make changes in lines 600 and
680 analogous to those in lines 570 and
650. The control code sequences in lines
580 and 660 differ only in their final
value; 5 and 9, indicating a left margin
five and nine characters wide. Check
your manual for a control code se-
quence 27, 108, n where n is a value to
indicate the character width of the left
margin, making any needed modifica-
tions in lines 580 and 660.

Lines 590 and 670 contain the Epson
control code sequences for specifying
the graphic modes. The mode desig-
nated by Line 590 is the one with a dot
density of 576 dots per line (72 dots per
inch). The last two values of that code
sequence indicate a maximum of
2*256=512 dots (the width of two
screens) that are to be printed per line.
If your printer manual has a different
control code sequence for this graphics
mode, change line 590 so that the code

A few tips on the typing of the driver
program, DR I verlt or DR I VERLE, should
prove helpful. Before you run the driver
being typed, save it on disk. Each driver
contains some pokes to memory, which,
if involved in a typing error, can cause

the loss of the whole program when it
is run. After saving the driver in its
entirety, run it, and when asked for a
two- or three-column printout, press 3.
If you made an error in the difficult-to-
type DR I VERLT lines 80 through 220 or
DRIVERLE lines 80 through 140, the
program will stop and report the
number of the line in which the error
occurs. Respond to the error report by
comparing your erroneous line with the
correct rendition in the listing and
rectify the error. Rerun the program and
correcting process until the driver
executes the screen replaced with
another prompt screen. Press BREAK to
stop the program.

Next, run the program and press 2 for
a two-column printout. DR I VERLT will
follow with another prompt, which you
may answer by pressing 1 or 2. Then the

request for a few moments wait occurs.
If DRIVERLT was mistyped, lines 380
through 500 or DRIVERLE lines 290
through 340, the program will stop and
report the errored line, allowing you to
correct it. Repeat running and correct-
ing the program until it can execute
beyond the screen containing the few
moments wait request. Finally, save the
driver program on disk.

Each of DRIVERLT and DRIVERLE pro-
vides prompts and messages to lead you
through the program in effecting the
desired two- or three-column printout.
You must, however, have ready on disk
the required screen files previously
saved by the desktop publisher program
DL. The eight or less character filename
of each screen file must adhere to the
structure described in Tables 2, 3, or 4.
In the three tables, the heading Screen
Image Printout Destination refers to
the location on the printed page of the
screen image.

The patch programs of listings 3, 4,
5 and 6 have given the program DL a
handy new feature that promotes pleas-
ing two- and three-column printouts. DL
now positions every character of any
font within a vertical distance of eight,
12, 16 or 24 dots on the screen with each
distance divided evenly into the 192 dot
vertical size of a DL screen. This means
that with a top margin setting of zero
via the M command of DL, each screen
will hold exactly 24, 16, 12 or eight lines
of characters depending on the font in
use. This guarantees that in a printout
of two screen images, one above the
other in a column, the spacing between
screen images will be indistinguishable

from the spacing between lines of either
screen image written with the same font.

Tables 5, 6, and 7 give the margin
settings specified by DL's M and W
commands that produce pleasingly
spaced two- and three-column high
capacity printouts. It must be pointed
out that the right margin setting for the
screens intended for a two-column, six-
screen printout must not exceed 240.
The reason is that for such a printout,
a 480 dots-per-line graphics mode must
be used and each column of the printout
cannot exceed 240 dots of the 480 dots
per line.

A typical session for producing a two-
column printout is as follows: It is
assumed that you will be making use of
the word processor input file feature of
DL. If your copy of DL does not have this
feature, you will have to write a screen
when others are employing the feature.
It is also assumed that you have on a
disk the word processor file in proper
form for input. The disk should other-
wise be blank.

Suppose the filename of the file is
mydoc. Your printer should be ready to
use. Load and run DL. Select a font most
suitable for your prospective two-
columned document. If you have a
DMP-105, DMP-106 or Epson com-
patible printer, make the left-column
margin settings in accordance with
Table 6; otherwise, according to Table
5. If you have only one disk drive or if
your copy of DL cannot address drives
when saving screens, there's no need to
swap the DL disk with the one containing

MYDOC.

Next, by means of the ASCII input

option of the I command, employ the
word processor input feature to fill a
screen. When the screen is full, opt to
have the remainder of the MYDOC file
recorded in a file called REST. Take this
option every time you fill a screen and
employ the O command to save the
screen on disk.

Choose a filename that is six or less
characters in length, for example, DUMP.
Then, when saving the screen, type the
filename as dumpli, where the final two
characters indicate that the screen
image is to be printed as the top part of
the left column of the page. If your disk
containing mydoc is in a drive other than
0, you must append to the filename the
usual colon and drive number.

Now, clear the screen and use the
word processor input feature to bring in
information from REST. Save the screen
as previously, but this time use the
filename DUMPL2, repeating the process
used to obtain the second screen file.
Save the third screen as DUMPL3. If you
used Table 6 to make the margin set-
tings, repeat the process again to save
another screen as DUMPL4. After saving
a full column of screens, make the right
margin settings in accordance with
Table 5 or 6 again. Clear the screen and
input another, saving it as DUMPRl.
Continuing the process analogously
until all six or eight screens have been
saved.

Suppose REST becomes empty before
all the required screens have been filled
and saved. Nevertheless, you need a full
complement of screens saved on disk.
Suppose that you were able to save
seven screens of an eight-screen print-
out. In such a case, clear the screen and
save it as DUMPR4. At this point, make
certain that the disk containing DRI-
VERLT or DRIVERLE is in Drive 0. (It is
convenient to have that program re-
corded on the disk containing DL.)

Select the high capacity screen dump
option of the O command to load and
run the program. Answer the two- or
three-column prompt by pressing 2.
DRIVERLT will ask you to press 1 if you
have a DMP-105 or -106, otherwise
press 2. Type the appropriate number
and you will be asked if you need
reminders about file and filename re-
quirements, after which, you are given
three options. Take the option to load
screens for dumping. If you do not have
more than one disk drive, now insert the
disk containing the screen files you just
saved. When asked for a filename, enter
DUMP if the screen file disk is in Drive 0;
otherwise, enter DUMP; and the appro-
priate disk drive number. The driver

program will load DUMPLl and DUMPRl,
initiating the appropriate screen dump
and printing will ensue. When the
screens of DUMPLl and DUMPRl are
printed, the driver loads DUMPL2 and
DUMPR2 and printing resumes. This
process continues until the two-column
printout is complete, at which time
there is given three options. If choosing
the option to return to DL, check that the
DL disk is in Drive 0, which loads and
runs DL. If the file REST contains more
information, prepare screen files for a
second two-column printout.

If writing a newsletter, for instance,

it's possible to have the newsletter name
span the two or three columns of the
printout. The following example indi-
cates how this is done.

Select a large sized font, say Font 1.
Suppose your newsletter, The Co Co-
Nut Chronicle, requires a two-column
printout. Clear the screen. Press the
space-bar and then type The CoCoNu. By
means of the T command, set both tabs
to either 240 or 250, depending on
whether the printout requires six or
eight screens. Then press the down-
arrow key to move the cursor to the
right (at 240 or 250). Augmenting the

word processor input feature is the
ability to move a printed line left or
right. Make use of that ability by press-
ing Shift-up Arrow until the u of The
CoCoNu is almost touching the cursor at
240 or about a third of the way past the
cursor if it is at 250. Select a suitable
font. Make the left margin settings
according to Table 5 or 6. Then press
enter twice. Use the word processor
feature to fill the rest of the screen and
save it as the top left column screen.

After saving all the screens for the left
column; clear the screen; choose Font 1;
using the M command, set the top and
left margins to 0; and type t Chronicle.
Select the text font again; make the
right margin settings in accordance with
Table 5 or 6; position down from the
newsletter name by pressing ENTER
twice; and fill the rest of the screen and
save it as the top right column screen.

If you do not have a word processor,
install the word processor input feature
in DL to acquire the ability to move
printed lines. (See September '88 issue,
Page 102.)

CoCo Graphics Designer Plus-
Signs of the Times

Every Tuesday is "Computer Day" at
my young son's school, and he regularly
brings home output from the day's session
at the keyboard. Not too many Tuesdays
ago, I walked into his room after work to
find a prominent addition to his decor: a
computer-generated banner hanging on the
wall, proudly announcing "JASON LOVES
MOMMY." A bit-image teddy bear rounded
out the proclamation, apparently serving
as the necessary link between human sen-
timent and hi-tech wizardry. My wife,
who helps out at the school regularly,
assured me that Jason had come up with
the text of his banner without any maternal
coaching. Obviously pleased with the day's
lesson, though, she wondered aloud why

we didn't have such a program for our
computer.

I'm happy to report that there is a de-
lightful program available for the CoCo
that does banners and much more. CoCo
Graphics Designer Plus, from Zebra Sys-
tems, Inc., provides the capability for
producing banners, signs and greeting cards
via an elegant point-and-click interface.

This program runs on any Color Com-
puter with at least 64K of memory. Yes,
that is correct: any Color Computer 1, 2 or
3. When I read the system requirements
page in the manual, I was amazed to see
that the program could also run on my old
silver 64K CoCo 1 as well as my CoCo 3.
It worked perfectly.

Upon running CoCo Graphics Designer
Plus, the user arrives at the main menu,
which is clear and simple (as main menus
should be). Your choices are Make Sign,
Make Banner, Make Card, Set Up Printer
and Set Up Data Drives.

A selection is made from among these
by directing an onscreen arrow with either
a joystick or mouse, and then clicking the
button. If you have never used this type of
interface before, you needn't worry: After
working with it for 1 5 seconds you' 11 know
everything you need.

Selecting Set Up Printer allows you to
configure your program disk for the type
of printer you have and the baud rate you
are using. This needs to be done only once
(assuming you don't change printers or
baud rates). The array of printers sup-
ported by CoCo Graphics Designer Plus is
nothing short of astounding. The list would
never fit on a single screen; it is accessed
by scrolling through a window and click-
ing on the appropriate printer.

110

THE RAINBOW May 1989

Having established that bit of trivia, the
other setup command enables you to spec-
ify which disk drives you will use to hold
collections of pictures, fonts (a font is a
particular way of shaping letters and
numbers) and border patterns. If you have
only one disk drive, you can completely
skip this step, and the program will assume
all of the above will be stored on Drive 0.
The program disk as purchased has six
different fonts, a collection of 32 pictures
and 16 font borders, all of which fit on the
program disk. However, the company sells
additional disks of fonts, pictures and
borders.

Once the setup procedures are taken
care of, you can proceed to any of the three
creative functions. Make Sign enables you
to create a one-page (8^-by- 1 1-inch) sign,
consisting of a combination of up to 14
lines of text, up to two pictures and an
optional border. For this function, the screen
is oriented around two activities. The right
side of the screen displays the current
border and the pictures being used for the
sign. The left side of the screen contains
menu items (or "buttons"), which can be
clicked on to do specific actions.

Buttons on the Make Sign screen in-
clude Select Picture, Place Picture, Select
Border, Edit Text and Preview Sign. Each
of these leads to an additional screen dis-
play. Also, there are buttons for Print Sign,
Save Sign and Load Sign.

Select Picture asks which of the al-
lowed two pictures you are selecting
(Number 1 or 2), and which set of pictures
you want to select it from. (Unless you
purchase additional picture disks, there is
only one set. See the sidebar "Clip Art for
Your Creations" for more information on
the picture disks.) It then loads the picture
set and allows you to scroll through it and
click on the picture you want.

Once you have selected a picture, you
can place it on the sign using Place Picture.
You have a choice of small, medium or
large pictures on the sign, although choos-

ing large limits you to one nearly full-page
picture. If you select small or medium, you
can use both of the allowable two pictures,
but both must be the same size.

The Place Picture function displays a
three-by-three grid for medium-sized pic-
tures, or a six-by-six grid for small pic-
tures. By clicking on a grid location, you
can place or erase either of the two pictures
at that location. You also have buttons for
filling the whole grid with one picture,
staggering them in every other location or
clearing the entire sign.

In addition to pictures, a sign can have
one of 1 6 borders around the edge. (Many
more borders are available on the optional
border disk.) The Select Border function
enables you to specify which collection of
borders you want to select from, loads that
collection, and lets you scroll through them
and select.

Select Picture, Place Picture and Select

Border are all implemented very smoothly,
and the commands and buttons function
intuitively. The pictures and borders are
shown onscreen as you select and place
them, which is a major improvement over
many programs of this type, which merely
name them, without letting you see what
they look like until print time.

The next function for making a sign is
Edit Text. The implementation here is not
quite as smooth as the picture and border
functions, although my outlook may be
biased by my extensive use over the last
few years of several point-and-click word
processing programs. CoCo Graphics
Designer Plus is not intended to be a word
processor, and thus only the most basic
capability is provided within the Edit Text
option.

Text editing is done in a 14-line win-
dow on the right side of the screen; buttons
on the left side allow you to specify posi-

In the Zebra Zone

When the CoCo 3 was released, there
was a sudden flurry of activity among Color
Computer enthusiasts. It was quite interest-
ing to watch. Photocopied technical manu-
als were in hot demand, hardware hackers
were dissecting circuit boards, and soft-
ware developers were scrambling to crank
out products that would take advantage of
all the new features. It's only natural, of
course, to want to investigate the new and
exciting.

For satisfied CoCo 2 owners, however,
there was understandable concern over the
fate of their faithful machine. Would any*
one continue to develop new products ca-
pable of running on the CoCo 2?

The answer, fortunately, is an unquali-
fied "Yes!" and Zebra Systems v Inc, is one
such company. The philosophy at Zebra
Systems, according to founder Stewart
Newfeld, is not to write for the most power-
ful machine, but to take popular concepts
and make them available in a quality pack-
age to the entire CoCo Community.

"We feel we can introduce half a dozen
products a year which will not require an
upgrade to the CoCo 3," said Newfeld. "We
will continue to support the CoCo 2,"

Incorporated in February 1983, Zebra
Systems has a history of providing high-end
capability to computers on the low end of
the price scale. Their original product line
boasted a 48-page catalog, including joy-
sticks, light pens and voice synthesizers, all
for the Timex Sinclair.

As the Sinclair market dwindled, the
company probed the IBM software market
but found it difficult to get distribution.

Retrenching, Newfeld investigated many
microcomputers before settling on the
Color Computer. Zebra Systems remains in
the surplus market, as well, buying periph-
eral devices in bulk and adapting them to
run on various; computers. It even has an
inventory of Timex Sinclair kits, sold pri-
marily to schools for training in soldering
skills and basic electronics.

Zebra Systems uses a variety of micros
in its business and has seen many changes in
the personal computer market over the
years. "People's expectations have
changed," Newfeld explained. "A light pen
today has to be really extraordinary or
people don't have much interest in it." The
interaction between man and machine has
changed, too, and the current trend is to-
ward easy-to-use, point-and-click graphic
interfaces. The original CoCo Graphics
Designer, released several years ago, was
entirely keyboard-driven. It took Newfeld
and programmer Jeff Street over a year to
rewrite it to provide the type of interface
and flexibility users are growing to expect.

The key to making future graphic inter-
faces more responsive, says Newfeld, with
his electrical engineering background, is
"supporting a precision mouse and generat-
ing sound without slowing down the
CoCo." To that end, he is working on a
CoCo peripheral that contains its own mi-
croprocessor, and is tentatively dubbed the
Turbo-Port.

"We want the CoCo 2 to really sing," he
says. If CoCo Graphics Designer Plus is
any indication, the music has already be-

know rf this was intensions I, or if (he addi-

quent to the completion of the documenta-

ups don't accurately reflect reaJity,

My otherminor gripe is that the conversion
programs require disk swapping, even if you
have two disk drives, as [ do, I realise ! can't

Regardless of whether you are a total non-

chasing one or more of these clip art collec-
tions. 'They represent high-quality work at an

tioning (left, right or centered), size (one
of four) and font (any from the designated
collection) for each line of text. It takes a
bit of practice to feel comfortable with this
editor, but all you're editing are 14 lines,
so it is not a major problem.

The Preview Sign function enables you
to see, either actual size or reduced, pre-
cisely what your finished product will look
like when printed. This can save lots of
time and paper if you haven't properly
aligned the text and pictures, or if the
desired effect isn't what materialized.

The Print, Save and Load functions are
totally straightforward. The only draw-
back is that the Save must be made to
Drive 0. No provision was made in the Set
Up Data Drives function at the main menu
for specifying which drive should hold
your finished product. This is rather an-
noy ing, since the program disk must reside
in Drive 0 and it is very close to being full
when you get it. There isn't room for much
more, so you have to resort to swapping

disks. I always get snippy when I am
forced to swap disks after I spent good
money on a second disk drive specifically
to avoid swapping!

The Make Card function works almost
identically to Make Sign. The basic differ-
ence is that you create two different pages
— one for the front of the card and one for
the inside. There is an additional button,
Select Page, that allows you to toggle
between the two while preparing the end
result. When printing a card, the first page

is printed upside-down in the upper-left
quarter of the paper, and the second page is
printed normally in the bottom right quar-
ter. By folding the paper in half twice, a 4 , /4-
by-5Vi inch card is produced.

The Make Banner function is consid-
erably simpler than the other two. The
available buttons are Select Picture, Edit
Text and Print. You can have one leading
picture and another picture to follow the
text. The Edit Text function is identical to
that in Make Sign and Make Card, and the
Print function has no hidden complexity.
There is no provision for saving banners to
disk, which is reasonable since they are so
easy to create.

I made a number of signs, cards and
banners with CoCo Graphics Designer
Plus and was thrilled with them all. I was
also fortunate to be able to try the addi-
tional font, picture and border disks. The
variety is awesome, and programs are
included that will convert the pictures to
CoCo Max /, //, /// and Max- 10 formats.

CoCo Graphics Designer Plus comes
with a 63-page users manual, which in-
cludes extensive appendices, a thorough
tutorial and a quick reference guide. It is
clear, easy to follow and complete. It is
also lavishly illustrated with sample screens
and contains a glossary that defines terms
such as "point" and "click."

CoCo Graphics Designer Plus is a top-
notch program. The graphics are superb;
the documentation excellent; the user inter-
face simple, easy to use and efficient; and
the price makes it a steal. I thoroughly
despise reviews that end with "Your soft-

it," but this really is one program that
everyone can use.

CoCo 1 , 2 & 3

Math Tutor-
Math Practice
and Educational
Arcade Action

Why should students give their teach-
ers Apples when they can give them a
CoCo and some educational software to go
along with it? Tandy's new educational
program on a ROM pack, Math Tutor, is
not only great for home use but could also
enhance an elementary math class.

I happen to be a serious person and like
to see computers used for serious pur-
poses. Education ranks high with me as a
reason for purchasing and using a com-
puter. Unfortunately, it ranks low with my
children. It's hard to tear them away from
the excitement of Color Baseball and the
shoot-'em-up action of games like Space
Assault in order to play some mundane
educational game.

I'm not of the opinion that all education
should be tremendously exciting, but when
made exciting learning becomes that much
easier. Most educational math programs
tend to be monotonous: The user is pre-
sented with a math problem; he gives the
answer; the computer rewards him with a
cheer or a raspberry; the user moves on to
the next question. The programmers of
Math Tutor have pretty much stuck to this
formula, but they have added something
more exciting called The Math Gallery.

The Math Gallery combines the action
of a video game with an educational drill.
The player stands at a shooting gallery in

the midway of a carnival. A balloon trav-
els across the top of a booth while a math
problem is presented. At the bottom of the
screen, the player has a gun that follows
the movement of the balloon. If the player
answers the question correctly before the
balloon reaches the other side of the screen,
the gun fires and the balloon pops. While
the game is going on, carnival music plays
in the background. If you haven't been to
a fair or carnival in years, the music is
guaranteed to bring on nostalgia.

Math Tutor not only covers addition,
subtraction, multiplication and division,
but it also covers fractions and algebra,
thus making it more extensive than other
math programs I've seen. In all of the
areas, with the exception of algebra, the
user has the option of choosing compari-
son problems. These problems require the
user to determine if two whole numbers or
fractions are less than, greater than or
equal to each other.

There is no multiplication or division in
either of the fraction or algebra problems.
However, in order to make the algebra
problems more difficult, you can choose
problems that mix addition and subtrac-
tion.

Within Math Tutor you can get help in
two ways. If you are absolutely stumped
on a problem you can press the ? key and
the answer will be given to you. There is
also a built-in scratch pad; you can access
this at any time by pressing the S key. This
is especially useful if you are doing diffi-
cult problems that involve carrying or more
than one operation.

There are five levels of play. The higher
levels increase the range of numbers and
include negative numbers. In the higher
levels of division, the answers may have
remainders; and in the higher levels of
fractions, the fractions may have different
denominators. Things can be made even
more difficult in the shooting gallery by
increasing the speed at which the balloon
travels across the screen.

The user not only has control over the
levels of difficulty but can set the lesson
size to 10, 20, 30, 40 or 50 problems. You
can also choose to have the problems pre-
sented in either a vertical or a horizontal

because it uses menus and formats that you
have used in other programs. For example,
the BREAK key always takes you back to
the last step.

An additional feature of Math Tutor is
the homework option. This is especially
useful for parents or teachers who want
their child or student to concentrate on
certain problems. The adult can create a
homework assignment and then save it to
tape for future use. I only wish it were
possible to print out the homework assign-
ments.

Other than the lack of a printer option,
Math Tutor is a fairly complete program,
and I have few complaints with it. All
single-digit numbers have leading zeros,
which may confuse children at first, but
my boys quickly adapted to it. One of my
sons wished that the program could time
him on his math problems and give the
percentage of correctly answered prob-
lems at the end of each lesson. Following
the Math Gallery you are given the per-
centage of correct answers given for ques-
tions asked in the Gallery, but you are not
given percentages on the questions an-
swered in your regular lesson. One other
problem is that there are no answers greater
than 99. This means that there is no three-
or four-column math, which my kids are
already doing in school. However, this
doesn't mean that Math Tutor is easy. Try
the Math Gallery in Level 5; I guarantee
that you won't pop too many balloons —
especially if you have chosen the high-
speed option.

On a scale of 1 to 10, one son rated this
program a 10, while my wife, my other son
and I each gave it a 9. If you have elemen-
tary school-age children and a CoCo with
at least 1 6K of RAM (a cassette recorder is
optional), then you should consider
purchasing Math Tutor.

Ore Ambush —
A Fight to the Death

Visit a bookstore and you'll probably
find a section devoted to novels about
heroes and heroines battling for good in a
land of sorcery. On other shelves you
might find role-playing games that let
players experience such adventures first-
hand. Through the magic of computers,
the pads of paper, charts and dice needed
to play these games have been eliminated.

SPORTSware, makers of War game De-
signer, also produce many different sce-
narios to complement their program. One
of these is Ore Ambush, a wargame set in
the Forest of Lynn, home of evil Ores,
good humans and elves. The goal is to
conquer the Ores, who have stolen the
chest of herbs belonging to the wizard
Shanndar. Exiting the forest, crossing the
river, entering the fort and defeating the
Ores are a few of the many challenges to
surmount in this game. The program does
not require the Wargame Designer to run,
as Ore Ambush is self-contained. How-
ever, those who own Wargame Designer
or Wargame Designer II can modify all of
the existing characteristics of this sce-
nario.

Ore Ambush requires a CoCo 3 and one
disk drive. Like numerous high-resolution
graphics-oriented programs for the CoCo
3, an RGB monitor is required to enjoy
Ore Ambush to the fullest. Many different
modules for various portions of the game
are loaded separately from disk. As no
copy protection is employed, making a
backup copy of the original is a must.

Loading the program is simple, requir-
ing the user only to type RUN"M". The
main menu then appears with six available
choices. If you don't own Wargame De-
signer, you will be able to invoke only two
of the options: Playing Ore Ambush and
Exiting to BASIC. The other selections are
obtained after copying certain modules
from the Wargame Designer master disk
to the Ore Ambush disk.

Play commences after the player desig-
nates the number of players (one or two)
and whether the game is new or previously
saved. The two main modes for the partici-
pants are movement and combat. The four
arrow keys as well as the P, O, K and L
keys control direction. Different terrain
squares have varying movement costs. Each
character in the scenario has a certain
range of movement and attack. This attack
is not necessarily successful and, as in real
battle, conditions can hurt the cause in-

stead of helping. Each turn ends after the
attack damage has been calculated for
each piece. If a unit does not attack for two
turns, a "resting " message flashes on the
screen, and the strength counter increases
in value for that character.

The Ores are normally invisible in the
one-player mode, but pressing SHIFT-3
during the human attack mode will put the
green and black monsters on the screen.
The first few times you play, you'll find
this mode very helpful in preventing an
embarrassing defeat. Selecting a two-player
game allows only one side's fighters to be
displayed at a time, with the other player
knowing the location but not the identity
of each character. The manual states that
Ore Ambush was designed to be a one-
player game. Novices may find it more fun
to play against a person of similar skill, for
the computer is a challenging opponent.

Game play ends when either side has all
of its units destroyed, the human side
occupies the treasure chest, or the player
presses Q to quit playing. The goal is to
occupy the representation of the treasure
chest in the upper-right comer of the screen.
Killing all the Ores is next to impossible,
and this kind of victory will take much
more time than usual. At any rate, destroy-
ing the monsters is not the way to run a
successful war.

Even expert gamers will find that the
computer-controlled Ores can be very tricky,
so don't count on winning until after you've
had some practice. The game save feature
is a necessity because one full game can
run into many hours (depending on your
skill).

The manual to Ore Ambush is relatively
short and requires only a brief amount of
study to understand. Hints and tips are
provided, although only experience will
allow the player to determine the best
strategies for victory. Also included is a
step-by-step process allowing Wargame
Designer to modify the maps, characters
and graphics.

At $15, Ore Ambush is inexpensive for
a stand-alone game with such attention to
detail. The RGB graphics are very good,
with a fair amount of detail and razor
sharpness. The composite screen, on the

Contributions to the rainbow
are welcome from everyone. We
like to run a variety of programs
that are useful/helpful/fun for
other CoCo owners.

WHAT TO WRITE: We are inter-
ested in what you may wish to tell
ou r readers. We accept for consid-
eration anything that is well-
written and has a practical appli-
cation for the Tandy Color Com-
puter. If it interests you, it will
probably interest lots of others.
However, we vastly prefer articles
with accompanying programs
which can be entered and run. The
more unique the idea, the more the
appeal. We have a continuing need
for short articles with short list-
ings. These are especially appeal-
ing to our many beginners.

FORMAT: Program submis-
sions must be on tape or disk, and
it is best to make several saves, at
least one of them in ASCII format.
We're sorry, but we do not have
time to key in programs and debug
our typing errors. All programs
should be supported by some ev
itorial commentary explaining
how the program works. We also
prefer that editorial copy be in-
cluded on the tape or disk using
any of the word processors cur-
rently available for the Color Com-
puter. Also, please include a
double-spaced printout of your
editorial material and program
listing. Do not send text in all
capital letters; use upper- and
lowercase.

COMPENSATION: We do pay
for submissions, based on a
number of criteria. Those wishing
remuneration should so state
when making submissions.

Revenge
of the Germs —
What Your Mother
Never Told You!

Do you remember your mother telling
you to wash your hands, leave the candy
on the sidewalk, and to wipe your nose on
a tissue, not your sleeve, so you wouldn't
"get germs"? And didn't you think that
germs spread by sort of cloning them-
selves? And I bet you thought germs were
little microscopic things, right?

Revenge of the Germs is a graphics
Adventure game (although when I saw the
title I figured it for an arcade game or anti-
virus program for sure) that will change
how you look at germs from now on.

After my precautionary backup, I booted
the game. I got to the part where it asked
"Read the objective?" (the background
info on the game) and got stuck. I pushed
every key on the keyboard and got no
response. Hmmmm. OK, I can't review a
game I can't get into, can I? I sent off a
note to the author, who called me with the
fix, and he promised to fix his master
copies also. T found this author to be like
most, willing to go the extra mile with
support. Now, onto the game!

I seem to be in a hospital bed. I can see
my feet sticking out, anyway. What in
Sam Hill happened? The door to my room
is trashed. Guess I'd better get up and see
what happened here.

Wandering through the hospital, I didn't
find anybody around and the doors were
locked. What I did find was this gigantic
blob, with hands, feet and head. That's a
germ, and it's too big to fit through the
door, but it seems to keep finding me —
usually if I happen to stay in a room too
long. It's definitely out to get me. The
germ is a random feature, and, oh yes, it

can kill you! I have to get out of here, but
I have to kill some of them on my way.
(Trust me! Hitting them does not work!)

The graphics are well done, with detail.
The objects disappear as you take them
and reappear if you drop them. This hospi-
tal comes complete with lobby, lab, wait-
ing room and operating room, along with
some rooms a hospital patient normally
doesn 't see. Did I mention that the elevator
disappears as soon as you step off?

The game accepts most standard com-
mands, except for the USE and HELP
commands. It also incorporates a few words
that weren't in my first-grade reading book.
Since you won't be able to finish this game
in one sitting, you'll be able to use the
SAVE and LOAD features that are included.

When I play Adventure games, I have
this habit of picking up every object I can,
and I absolutely hate to drop anything
because you never know if you're going to
need it later. This game accommodates my
habit. You should see how much stuff you
can carry! And for those who don't know
which way is north, the directions in this
game are left, right, forward and back. The
only thing I really found lacking in it was
a SCORE command. I like to gauge my
progress by the points I have accumulated.
For those of you who like to be surprised,
the lack of a score won't bother you.

Included with Revenge of the Germs
are three pages of very complete instruc-
tions. The instructions cover startup of the
game, making backups, sample text, and
the conditional guarantee from The Soft-
ware Systems. It's recommended for ages
10 and up, and I suspect that's because it
requires some logical thought and creativ-
ity to solve. If you happen to get stuck
while playing the game, just grab a couple
of friends or family members. You'll get
plenty of suggestions.

Revenge of the Germs will work on
your Color Computer 1, 2 or 3. A single
disk drive is also required. The game fits
on one disk, so there is no disk-swapping.
If your original disk doesn't work for some
reason, send it with $1 for handling charges
back to The Software Systems for a re-
placement.

I really enjoyed this game. I'm a sucker

for graphics, and I always get anxious to
see "the next scene." This game didn't
disappoint me in that respect. Once I
remembered a few basic rules about ad-
venturing, I was able to solve it. At $9.95,
it's a real bargain, affordable even on a
paper carrier's salary. Also, while you're
killing germs, you'll be saving not only
yourself but also real beasties, because 25
percent of all profits from the game will be
donated to the Nature Conservancy. I
commend the author for this concern. And
his donations.

Printer Drivers
for Home Publisher-
More Support
for the OS-9
Desktop Publisher

Did you buy the Home Publisher OS-9
desktop publishing program from Radio
Shack only to find that you would have to
purchase a new printer just to get a hard
copy of your efforts — Tandy did not
provide drivers for many of its own print-
ers. And isn't that the whole point of
desktop publishing — making printouts?

Fortunately, Tandy later provided driv-
ers for the DMP printers free for the asking
to registered Home Publisher users.

I loved Home Publisher so much that I
went out and bought a new Star NX 1000
Rainbow color printer, which was compat-
ible. Having purchased three printers over
the years from Radio Shack, I too was
disappointed that Home Publisher did not
support the CGP-220 color printer. Well,
wish no more, for Home Publisher has new
drivers for seven popular printers. Please
note that the disk of add-on drivers is an
Express Order item and may not be stocked
by your local Radio Shack store. (Also,
note that Home Publisher is for the CoCo
3 with a disk drive and a compatible printer.)

While I have only one printer supported
by this package of printer drivers, I will
note for you the special considerations you
should be aware of from the instructions
included. Although the documentation is
only three pages of information, it seems
to be complete and all that is needed. The
Home Publisher add-on diskette includes

drivers for these printers: Tandy CGP-220
and DMP-1 10, C.Itoh 8510, Epson MX-
80, Okidata 20, Panasonic KX-P1090 and
Star SG- 10.

The instructions indicate that no spe-
cial considerations need to be made for the
C.Itoh 85 10, Okidata 20 and the Panasonic
KX-P1090. If you are using the Epson
MX-80, the printout will be only 5!4 inches
wide. The reason for the narrow printout is
the 960-dot line of this printer. For the Star
SG-10, DIP switch settings are noted.

Two drivers are included for the DMP-
1 10 because a full-screen printout is 1 inch
longer than will fit on standard paper.
DMP-1 10N is the full-screen version, and
several options are available to you. You
could have it overlap two pages of stan-
dard paper, use continuous paper or load
your printer with a sheet of 14-inch paper
to avoid using two sheets. The second
driver for the DMP- 1 10 is the DMP-1 10S y
which will truncate the bottom 10 percent
of the page so that it will fit entirely on a
single page of standard paper.

The only special consideration for the
CGP-220 is that if you want to use the
printed borders you should set the left and
right margins to .09. This allows eight dots
plus one blank dot for the border pattern on
each side. If you think I saved the best for
last, you are right! If you read the first line
of info for the CGP-220 where it says
"will only print in black and white," don't
believe it! If you want the page to print in
other than black, even in multi-color — you
can!

How to Get Color on the CGP-220

To print in a color other than black, just
send the color commands to the printer
using the OS-9 display command (yes,
it is in there and available for you to use)
before starting Home Publisher for print-
ing; the software will not reset the printer
to black.

To print the page using green, enter
display IB 54 32 >/P from the OS-
9 prompt and press ENTER. Then start up
Home Publisher as usual. When you print
the page it will be printed in green and
white. To print in another color just change
the 32 in the display command to the
Hex value of the color you want. For a
multi-color page you will have to do a
little more work and planning.

If you only want the border a different
color, this is how it's done. First, set the
printer with the border color from OS-9
using the di spl ay command. Next, print
a blank page from Home Publisher, select-
ing the desired border pattern. Then exit to
OS-9 and set the color for the rest of the
document. Bring up Home Publisher again,
then load/create the page; reset the paper

in the printer back to the top of the page
before printing the second color.

The easiest way for me to realign the
paper for the second color was to tear the
roll paper off even with the tear bar on the
printer. When I said multi-color that's just
what I meant!

To print a page in more colors you
would create a separate page for each
color, saving each of them in a separate
file. To print the page you have to set the
print color from OS-9, restart Home Pub-
lisher , and load and print the color, repeat-
ing this for each color until your master-
piece is done. It's a lot easier than it sounds
— try it! If you have a color printer other
than the CGP-220, you could do it the
same way: just send the color commands
for the printer you are using to get the same
results (using the proper printer driver for
the printer you are using). For those of you
who do not have a color printer but have
different color ribbons, you could merely
change the ribbon for the printing of each
color.

I hope this information will be of help
to you even if you do not need the drivers
on this disk. Home Publisher is a very
good system made even better with this
add-on set of printer drivers. Personally, I
feel that users should not have to pay 20
bucks extra to get drivers that should have
been in the original package. But it's nice
that Tandy got around to providing them.

HAWKSoft's
Keyboard Extender —
Expand Your CoCo's
Horizons

I'm extremely fortunate to have my
CoCo on its own table. I have almost
enough room for everything, and I'm able
to type pretty much as my typing instructor
in high school taught me.

I also know that not everyone is as
fortunate as I am. Your computer table
may be too small or cluttered. If it is, I bet
that you 've wished you could arrange your
equipment more comfortably for the times
when you type in those long BASIC list-
ings from THE RAINBOW. There may be
some hope for you.

118 THE RAINBOW May 1989

HAWKSoft can provide you with a
keyboard cable that allows you to remove
the keyboard from the CoCo case and use
it within a 5-foot radius. You could put the
keyboard in your lap, or you could put it on
the computer table, leaving the CoCo on
the floor. Or you could try another ar-
rangement. Of course, all this freedom
comes at a price, and I don't mean money
— you have to open your CoCo. The dreaded
warranty seal needs to be violated!

Fortunately, the procedure to install the
keyboard cable is fairly straightforward. If
you are familiar with the operation of a
screwdriver, you probably won't have too
much trouble. And if you do, you can give
the company a call. They were friendly
when I called for a little advice. The single
sheet of instructions was a little confusing.
I talked to Chris Hawks of HAWKSoft and
he assured me he would try to make them
a little clearer, maybe even adding a dia-
gram or two.

Opening the case is simple: Remove six
screws from the bottom of the computer
case (the sixth screw is under the warranty
label, which means you have to poke a
hole through it to get this screw out). After
vou lift the lid from the CoCo and its
innards are exposed, you unplug the key-
board cable. Then you carefully insert the
leading edge of the dual in-line plug into
the keyboard connector. Stretch out the 5-
foot extender cable and plug the keyboard
into the card edge connector. Put every-
thing back together on the CoCo and ex-
tend your reach.

If you are worried about damaging your
keyboard, don't be. With a little care, the
keyboard should last just as long out of the
computer case as in it. Tandy enclosed it in
a protective case. The cable itself is a flat
ribbon cable that, with a little care, should
last a long time. In fact, the whole key-
board cable assembly is made from indus-
trial-grade parts. There is gold plating on
the connectors, which means reliability.
This cable can be used on any CoCo 2 or 3,
and the sample I received was 5!/2 feet long.

A few things need to be considered
before installing this product. Once the
keyboard is removed from the CoCo, all
its guts are exposed, and they are very
fragile. The parts are especially sensitive
to static electricity and loose paper clips,
etc. It would be wise to cover the hole with
something or to buy a spare keyboard to
use with the extender cable. The mylar
connector on the keyboard scratches eas-
ily, a fact that's mentioned in the manual
but cannot be emphasized enough: You
should be extremely careful not to damage
this cable, or you will be buying yourself a
new keyboard.

One complaint I have with HAWKSoft's

Keyboard Extender is an unused row of
pins on the plug that goes into the key-
board connector. This makes the plug sit at
an angle on top of several other compo-
nents near the connector. I think cutting
off the unused row of pins would eliminate
any potential problems. Another complaint
I had was with the instructions, but Mr.
Hawks assured me he will work on them.
They were adequate for a hardware hacker,
but I think they would have confused the
neophyte. [Chris Hawkes reported that he
has rewritten the instructions, and also that
he has cut off the unused row of pins on the
plug of his unsold cables.]

Should you buy this product? If you
have a need to move your keyboard around,
this well-made extender cable will do the
job nicely for you.

BASIC Unravelled
Series —

Learning the Ropes

Imagine having complete control over
the BASIC in your Color Computer, know-
ing the intricacies of its operation at every
point as it runs your programs. Now imag-
ine being able to change BASIC to work as
you want it to, adding and improving
commands as you desire, and being able to
easily interface your own machine lan-
guage routines with BASIC to perform
special functions.

With the BASIC Unravelled series these
things don't have to be limited to your
imagination. BASIC Unravelled is a three-
part series containing commented source
code (assembly language code used to
create machine language programs) of all
of the ROMs in the Color Computers 1 , 2

u--— --- ----- -----

Before I go any further, let me mention
that these books are not for everyone. The
best use of them can be made by someone
who understands assembly language on
the CoCo. I would recommend at least a
general knowledge of assembly, but it
isn't necessary for you to actually be a
hard-core assembly language programmer.
These books are not instruction manuals
for programming, but rather are reference
manuals. And they are extremely useful
reference manuals.

Each of the books contains not only the
disassemblies but also specific informa-
tion dealing with certain features of BA-
SIC that the particular book covers. The
first book, Extended Color BASIC Unrav-
elled, covers both Color BASIC and Ex-
tended Color BASIC (which were joined
into one chip on the CoCo 3). It contains
the source listings for both of those BA-
SICS. Also covered are the various
"Equates" and BASIC'S direct page, inter-
rupt vector tables, command interpreta-
tion tables, RAM vectors, and variables
that BASIC uses. In the beginning of the
book is a general description of how the
BASIC interpreter works and how vari-
ables are stored. Several ROM routine
entry points are listed, along with the reg-
isters that are affected by them. Also shown
are the changes made to Color BASIC 1 .2
and Extended BASIC 1.1 when the CoCo
3 powers up. Some things the new version
doesn't have are the differences among
Color BASIC 1.0, 1.1 and 1 .2, and also the
differences between Extended Color BASIC
1 .0 and 1,1. Those with the older versions
will find some anomalies in this new book.

The second book is Disk BASIC Unrav-
elled, It covers Disk BASIC for all ver-
sions of the CoCo and even has separate
disassemblies for Disk BASIC 1 .0 and 1.1,
making it much easier to follow them than
to check a listing of the differences. This
book also explains how the FCB (File
Control Block) of Disk BASIC is set up,
and it offers details of the FAT (File Allo-
cation Table), the way the directory is
organized, and on communication with
the floppy disk controller. It also contains
a listing of the direct page and variables.

The last book, Super Extended BASIC
Unravelled, deals with the new BASIC of
the CoCo 3. The disassembly in this book
is especially well-communicated and was
very understandable. Some of the addi-
tional information in this book deals with
the hardware differences between the CoCo
3 and the earlier CoCos, the Memory
Management Unit, super high-resolution
graphics (including color generation and
palette use), new CoCo 3 interrupts, and a
chart showing the equivalent colors be-
tween composite and RGB monitors.

The possibilities these books present
are almost limitless. Just by looking at the
direct-page variables, you can see hun-
dreds of peeks and pokes to monitor and
alter BASIC. Knowing what BASIC is
doing and when it is doing it can open all
kinds of areas in your programs. When I
was working on a remote terminal driver
program (which is similar to REMOTE 2
but uses the RS 232 pack) for my BBS, I
was able to incorporate many extremely
useful features into it by referring to these
books. Assembly language programmers
have a huge source for information on how
certain functions can be performed, and
this programming information can be in-
valuable.

The books are available separately for
$39.95, $19.95 and $24.95 for Extended
Color BASIC Unravelled, Disk BASIC Un-
ravelled and Super Extended BASIC Un-
ravelled, respectively. Or, you can buy the
first two for $49.95 or all three for $59.95.

These books have been called "defini-
tive" by a well-known CoCo programmer,
I say they are that and more.

DS-69B Digisector—
Capture Video
Images

The Micro Works DS-69 Digisector
was first introduced in 1 984, making it one
of the first video digitizers to become
available for the Color Computer. In the
nearly five years that the Digisector has
been on the market it has been updated
twice, first to the DS-69A and then to the
current DS-69B; the software has been
updated several times, and is now at Ver-
sion 3.3 — Micro Works calls it III.III! By
any standard, the Digisector is still holding
its end up and remains one of the best
choices in its field.

The Digisector itself is a cartridge that
goes in one slot of the Multi-Pak Interface
or a PBJ C-C Bus. The only control is for
width; all other adjustments are handled
by the C-See software. The video input
takes the signals put out by TV cameras
(black-and-white or color, including most
camcorders), VCRs, videodisc players and
other video sources. There is a filter to
remove the color "subcarrier" signal so

that it won't interfere with the digitizer's
operation.

Once you've run the setup program to
specify your system (a CoCo 1 , 2 or 3 can
be used), printer and expansion bus, you
just RUN "C-SEE" to start the program.
From this point you can run the program
two ways — either using the keyboard, or
with a joystick or Color Mouse. Each
option on the main menu has a letter; each
option on the submenus is numbered. So,
to print a 16-level image you'd press P
(Printer menu) and then 2. With the joys-
tick you'd move a black bar to the printer
entry, press the firebutton, then go to the
Print 16 level entry and fire again. The
joystick lets you work the Digisector from
behind the TV camera, which should save
quite a bit of running back and forth.

Pressing G will start the fast five-level
scan, which uses the 256-by-192 graphics
mode but scans a 128-by-128 image; you'll
see the output of your camera (or what-
ever) on the CoCo screen. At this point
there are two ways to adjust the picture;
you can either adjust brightness and con-
trast individually, or you can adjust con-
trast (with C-See taking care of the bright-
ness) and then play with the vertical and
horizontal dithering to get the best results
before saving the picture file.

The DS-69B 's major attraction to many
users (including me) is its 16-level capa-
bility; you can grab an image at either 1 28-
by- 1 28 or 256-by-256 resolution, save it to
disk and print it on a variety of printers.
These include Tandy's DMP- 100, 105,
120, 200, 400 and 500 as well as Epson,
Star Micronics and other dot-matrix print-
ers.

The 1 6-level mode is almost as easy to
use as the five-level; you get a fast scan
screen and set the brightness and contrast,
then press the ENTER key or firebutton to
start the scan. On the CoCo 1 or 2 you'll
then see a five- level dithered picture; on
the CoCo 3 you'll get a much better dis-
play using the 3's gray-scale capabilities
along with some dithering. (This display
will be quite a bit taller than usual; an RGB
monitor should be able to handle it with no
difficulty, but some TV sets may cut it off
at the top or bottom.) There's also a 16-
color mode available, which produces a
rather bizarre effect but is actually useful
for gray-scale differentiation; similar tech-
niques are used for weather radar, satellite
photos and medical imaging systems.

There's a catch to the 16-level capture
modes; they're slow. The 256-by-256 mode
takes 15 seconds to scan the image; the
1 28-by- 1 28 mode takes three seconds, and
your subject must be absolutely motion-
less during this period. This makes the
Digisector more suited to use with a cam-

May 1989 THE RAINBOW 121

era than for grabbing frames from TV
programs. If you want to use a VCR to
display still frames, it has to be capable of
doing it without any noise or sync prob-
lems; if your still picture jiggles up and
down the screen, or if you see noise bars,
the Digisector will be unable to handle it
because it deals with the video signal much
differently than a TV set does. (If you have
a LaserVision player, the "CAV" discs
that play for 30 minutes on a side will
provide good freeze frames.)

The 1 6-level pictures print very nicely
on most printers; the 256-by-256 mode
provides especially good results. The only
difficulty here (a common one with pro-
grams that print graphics) is that you will
need a fresh ribbon to get a good result in
dark areas; if the ribbon is somewhat worn
you'll get a washed-out picture. The heavy
printing load also wears out ribbons rather
quickly, simply because of the high den-
sity involved.

Overall, the DS-69B Digisector is a
winner in its field and still the champion in
the CoCo frame-grabber business.

Dino DataBase —
Yabba Dabba Doo,
Fred and Dino, Too

Well, maybe only Dino and a few of his
buddies, cousins, aunts and uncles, etc.
Dino DataBase is a disk-based database
containing all the classified types of dino-
saurs (193) and information on how each
name is pronounced (like a dictionary list-
ing, and it includes the Latin meaning of
the name), the dinosaur's order and fam-
ily, the time period in which it lived, two
or three places where it was discovered
(shown on a graphic world map), its length
from head to tail, and to top it off, a
"picture" of the animal.

Dino DataBase is a static database in
that you cannot add or delete entries, but
since it covers all the known classifica-
tions of dinosaurs it should not become
outdated — barring some new discovery.
It works on the Color Computer 3 with at
least one disk drive.

Getting started is as easy as turning on
the machine, slipping the disk into Drive 0
and typing RUN"D". You will be asked if
you are using an RGB or composite moni-

tor or TV, and the introductory screen will
appear.

The screen is divided into four "win-
dows," each of which holds some type of
information on the current dinosaur. The
upper-left window lists the name of the
dinosaur and its correct pronunciation,
followed by the Latin meaning of its name.
This is interesting because many times
you can look at the picture and see how the
dinosaur got its name. For example, Had-
rosaurus means "big lizard." It looks like
a lizard and is 30 feet long (that's big in
my book).

Following next are the animal's order
and family. The manual devotes two pages
to talking about how classifications are
made, making it as educational as the
program itself. Next, the listing gives the
time period in which the animal lived,
such as the Late Triassic. A simple time-
line would help immensely. (I had a chance
to talk to the programmer of Dino Data-
Base, and he said he is considering adding
a timeline to the manual.)

The last two pieces of information tell
two places the dinosaur was discovered
and its length in feet. The upper-right
window shows a line drawing of the dino-
saur.

The lower-left window lists other dino-
saurs related (in the same family) to the
current dinosaur. The "main" dinosaur of
the family is highlighted. Through experi-
mentation it seems that the "main" dino-
saurs are the only graphic entries in the
database. The lower-right window displays
a world map with crosses to indicate the
two locations where the dinosaurs were
found. The layout of the windows is pleas-
ing and consistent, so younger users will
always know where to find specific infor-
mation.

The commands are listed onscreen in a
pull-down menu. Pressing any key will
page a cursor through the seven com-
mands. You can "Shut" the pull-down
menu off to see the full screen. "Next" and
"Back" page through the database, for-
ward and backward, respectively. "Help"
explains the commands in the pull-down
window, and "Quit" exits to BASIC.

The meat of the program lies in the
"Find" and "View" commands. Find
searches for a specific dinosaur. If the
correct spelling is not known, the first two
or three letters will get you close. If you
don't get the desired dinosaur right away,
you can type in the first four letters and
search the database again. After finding
the dinosaur you want, you can go to the
View screen to see the entry's informa-
tion. My only suggestion here is that I
would like to see the database alphabet-
ized. This would allow me to type in the

first three letters, then page forward or
backward, alphabetically, to find the spe-
cific dinosaur I am looking for rather than
struggling with a fourth letter. For those of
us who have trouble spelling, the manual
provides a list of all dinosaurs in the data-
base.

The View command works like Find,

H . . ♦ Not only does Dino
DataBase teach students
about dinosaurs, it will also
introduce many of them to
online searching and the
necessary skills for finding
information within a
database structure. "

allowing you to type in the name, or as
many letters as you know, to locate a
specific dinosaur. This is called "rapid
view" because it involves no graphics. By
paging through the database you can dump
any entry you want to your printer. Each
entry is five lines long, allowing about 1 1
entries per page. When exiting the View
function, you return to the main screen,
but not the entry located with the view
command. You return to the same entry
you left when entering View. (View is a
faster search, containing text information
on all dinosaurs in the database — but no
graphics. Search allows you to view only
the main members of a family, but it does
show graphic information.)

The manual, 1 1 pages long, is educa-
tional. The introduction briefly describes
what happens when a dinosaur is discov-
ered. The manual also goes briefly into
how dinosaurs are classified. The remain-
der tells how to use the program. The
manual is easy to read, and getting up and
running takes only about 20 minutes.

Overall, my only suggestion is that the
user be informed of how the database is
ordered. If I know how a database is or-
dered I can determine how to find an
entry. As it stands, I have no idea as to
why one dinosaur follows another in the
graphics window. The reason I mention
this is because not only does Dino Data-
Base teach students about dinosaurs, it
will also introduce many of them to online
searching and the necessary skills for find-
ing information within a database struc-
ture.

I give Dino DataBase a big Yabba Dabba
Doo! It's educational and has a very im-
pressive user interface. It's easy for young-
sters to use and simple to learn. Dinosaurs
are a hot item with kids today — just look
around the malls. And if your child is
crazy about them, this might be the best

CoCo3

CoCo 3 Wheel-
Out for a Spin

Welly I wonder what's in the oV mailbox
today? Bills, junk mail, newspaper, pack-
age from RAINBOW. . .Hold on! What's
this (rip, rip, tear)? Oh boy! My next
review assignment! What did I get this
time? CoCo3 Wheel — a Wheel of Fortune
game? Yuck! 1 hate that game!

That was my initial reaction to CoCo 3
Wheel. I may be the only person alive who
never really understood why anyone would
want to buy a vowel — so to be honest, I
wasn't immediately thrilled with the pro-
gram in front of me.

Well, let's fire it up anyway and see
what happens. Where are the instructions?
No instructions? Either someone fouled up
or this is incredibly easy to run. Okay, I'll
do a DIR. Hmmmm, one BASIC file, one
ml file. RUN"WHEEL". Ah! A title page
and some instructions, good. I guess 1
should have read the label where it says
RUN" WHEEL".

As you may have guessed, from this
point game play is very much like the TV
version of the show. You are presented
with a puzzle consisting of blanks instead
of letters, and you must guess letters and
eventually guess the puzzle. This version
does not have Vanna walk over and turn
the letters for you. I've seen a version with
that feature: It's cute the first few times but
gets old real quick and slows up the game.
I did not miss her.

Wheel requires a CoCo 3 and a disk
drive. The only disk-specific command I
found in my listing was a LOADM com-
mand, but no indication was given as to
whether or not a tape version is available.
Because it uses the 3's Hi-Res screen, it
will not run on CoCo 1 or 2, but a version
is available for those machines. Two hundred
puzzles are included in the program, 50 in
each of the four categories of persons,
places, things and phrases. That should
keep you busy for a while. But if it doesn 't,
instructions are included in the listing of
the program for adding your own.

After playing a round or two, Becky
and Lori, my daughters, had discovered
the new toy. The usual question came:
"Daddy, can we play?" Not being a Wheel
fan, after a few instructions, I willingly
surrendered the keyboard and went to see
what was happening on the ball game. An
hour later I realized they were still playing
the game. My team was losing, so I parked
behind them to watch. They seemed to be
stuck on a rather lengthy phrase and asked
me for help. Since the used letter board
showed that my two letters had already
been guessed, we decided to buy a vowel.
(I'm so ashamed.) The E's provided just
enough of a clue for a correct guess. They
wanted to play again, this time the two of
them against me. They beat me! Twice!

Wait a minute! I thought I hated this
game. Maybe it's just Pat and Vanna I
don't like because this is fun. And if you
think I'm going to stop just because a 12-
and a 9-year-old cleaned my clock for me,
you're crazy! Seriously, as I stated, I am
not a "Wheel Watcher." I don't like the
show. But this is a fascinating game, and I
enjoyed playing it. A friend and I plugged
in some (how should I phrase this?) adults-
only puzzles. That was a real riot. Now for
the "howevers."

Game play is very impersonal. I prefer
to be called Randy rather than Player 1 or
Player 6. Since the program is written in
BASIC, a short input statement can take
care of that.

The game spins the wheel by using a
palette-switching routine. It apparently uses
15 of the 16 available palettes, which
makes for a colorful wheel but also causes
the lettering on the screen to change colors
as the wheel spins. Once it stops, the
writing on the screen returns to a preset
color except for the place holders for unre-
vealed letters. This sometimes creates eye-
straining color combinations, like yellow
on white. A better idea may have been to
use only eight palettes for the wheel and
reserve the other eight palettes to fancy up
the text display.

A handy feature is the ability to give up
on a puzzle. This is quite nice when the
children play and have never heard of the
person, phrase or whatever. This feature

could have been enhanced by the addition
of a "vowels only remaining" signal.

Also missing is the bonus round. I was
able to plug in a routine that lets you select
five consonants and a vowel, and gives
you one guess at the puzzle.

Multiple-round play would have been a
big plus. As is, if you elect to play again,
all scores are reset to zero. A grand total
score, at the end of, say, three rounds,
would be great.

The program comes to us from
SPORTS ware and sells for $21, which I
feel is just a bit high for the game as
presented. CoCo 3 Wheel for the CoCo 3 is
fun and habit-forming. With just a few
minor improvements it would be an excel-
lent addition to your games library, and at
the current price, more than a bargain.

KJV on Disk-
Books of the Bible
on Your CoCo

KJV on Disk is for anyone who studies
the Bible. The two disks 1 reviewed con-
tain the text of the books of Luke and John
in the King James Version of the Bible in
ASCII code. One of the disks divides the
24 chapters of Luke into seven files. The
author's intentions are, eventually, to have
available the entire Bible on disk, starting
with the New Testament. Matthew and
Mark are also available.

A README file on each disk explains
that the files were created with Telewriter-
64 and that a word processor is necessary
to make any practical use of them. How-
ever, a file called TYPE allows the view-
ing of the files a line at a time, which can
be really ugly on a CoCo 2 with no lower-
case option.

Since a program review ought to help
potential buyers judge how to utilize the
program, I'll offer some thought about
how this program might be used.

First, the obvious purpose is to read
verses off the screen. Unless you are really
into hi-tech, this doesn't seem to have any
advantages over reading them out of your
own Bible. I do see that this might be an
application for the seeing- impaired. The
larger screen letter sizes could be chosen.
In this case, the TYPE program, which
produces text on the 32-character CoCo
screen, might find further utility.

1 24 THE RAINBOW May 1 989

But there are possibilities other than
simply reading the file. Students of the
Bible are often ministers and Bible teach-
ers preparing sermons and lessons to be
delivered orally or included in material for
publication. A not-too-involved procedure
can be used to import portions of these
files for use in another word processing
document. For Telewriter-64, first save
the quotation under a unique name, then
read in the file (under "Append") at the
point in your own document where you
want the quotation to appear. Many other
CoCo word processors support block saves
and reads.

Another application would be to find
words and phrases using your word proc-
essor's search function, much the same
way a concordance does. You are limited,
however, by the portions of each book
contained in memory at any one time. A
similar idea is to gather such facts as how
often the name "Jesus" or the word "sav-
ior" is used in any given portion of these
books.

Another use that might not appear
obvious is to print the text or portions of it
to have scriptures you can read and anno-
tate. Many people like to highlight and
comment on the printed page when they
read. It helps them concentrate on themes
within the work or save flashes of ideas
before they fade away. Writing all over
one's personal Bible, however, is not a
good idea for a number of reasons. An
easily made printout provides a good alter-
native.

I am sure that many of you are able to
think of more inventive ways to employ
these text files. Other word processors,
especially those available on a CoCo 3, are
also likely to increase the possibilities for
these files.

One of the restrictions you may face is
on the longer text files. The documenta-
tion says that 24K of buffer space is neces-
sary. The unpatched version ofTelewriter-
64 is able to handle this. However, if you
are using a CoCo 2 with Telepatch, you
must make a new patched version of TW-
64 that does not include the disk I/O menu
routines in RAM. This frees 4K of RAM
that is needed on five of the files on these
two disks. No modifications are necessary
if you're using Ultra-Telepatch.

Using TW-64, the 61 -character screen
offers the least problem with wordwrap
although there is an occasional blank line
on the text screen.

If you purchase any of the programs in
this series, I suggest you make a label for
each disk jacket that tells the chapters
contained in each disk file. This informa-
tion is found on the disks in a README file.

Each disk in the KJV on Disk series

costs $3, a quite reasonable sum if you feel
that these Bible books would be at all
useful to you.

Vehicle Cost
Printout —

Time for a Trade-in?

Have you ever wondered how much it
really costs to operate your car? Is it really
running the same after all these years?
Would you be better off keeping the fam-
ily "klunker" or buying a new car? Ve-
hicle Cost Printout can help you deter-
mine the answers.

" Vehicle Cost
Printout is intended
mainly to provide an

annual report
printouty but it can
also be used to
obtain monthly
and/or quarterly
printouts if you so
desired

Vehicle Cost Printout will run on any
Color Computer 1 , 2 or 3 with Extended
BASIC and 64K of memory. This program
is available for either a cassette- or disk-
based system. You also need a "smart"
printer capable of underlined, condensed
and elongated printing in order to have a
hard copy of your car's cost statistics,
including cost per mile.

The first thing you should do after load-
ing the program is to configure it to your
printer (it comes configured for a C. Itoh
8510). Therefore, you should be familiar
with your printer's baud rates, a few of its
function codes and Extended BASIC'S
EDIT command. There are only a few
lines to edit, and the manual gives you a
complete description of the codes and line
numbers, so this should be no problem for
most people. Configure the program, make
a backup for your own use, then put the
original in a safe place.

The program itself is relatively easy to
operate as it is menu-driven, and the menus
are self-explanatory. Vehicle Cost Print-
out allows you to input data, save/load
data files, scan/modify or insert/delete
entries, and, of course, send data to your
printer for a hard copy. There is enough
room in the program's database for an
average of about 20 entries per month,
which should be plenty for anyone. You
have to make a separate data file for each
vehicle. Categories of data include date,
cost of fuel (per gallon), total cost of fuel
(full tank), mileage, other expenses and
mileage at the time you incur these ex-
penses. There is even a line for invoice
numbers.

Vehicle Cost Printout is intended mainly
to provide an annual report printout, but it
can also be used to obtain monthly and/or
quarterly printouts if you so desire. The
program allows you to decide if you want
a grand total for any of these time periods.
If you want to carry the annual total over
into another year, as you have to keep a
separate data file for each year, you must
change a few variables in the program
itself. The manual provides adequate docu-
mentation in order for you to accomplish
this.

There's one problem I encountered while
using this program. The manual states that
"The first entry is for setup only and will
not give a full printout, nor will the dollar
amount for fuel be added to any totals."
Simple enough, right? Well, I had input
my first entry (the setup screen), then
entered my second entry using the same
mileage figure as in the first entry. Ex-
ample: For the first entry, the odometer
mileage equalled 100 miles; the second
odometer entry had mileage at 100 miles
also. Anxious to see the printout on paper,
I directed the program to begin printing,
but before it could finish the program was
stopped by a "/0" Error (can't divide by
zero). This happened because the program
calculates that 100-100=0, which is cor-
rect, but when it goes on to divide total
costs by mileage to get the cost per mile —
it can't because, as stated before, the
computer cannot divide by zero.

This is a minor problem, I'll admit,
because most people will not use the pro-
gram in this fashion. But I was a bit con-
fused until I looked at the program and
found out how it carried out its calcula-
tions. Therefore, I think the manual should
go a little further in explaining the purpose
or function of the setup entry. Other than
this one exception, the program performed
flawlessly in all areas.

The manual is well-written in that it is
straightforward, takes the user through each
function step-by-step and offers some good

CoCo3

Fontgen —

CoCo 3 Fonts, Icons

and Borders

Hi-Res graphics been a little boring
lately? Need some nice frilly borders to
impress your significant other? Want to
make a big bold statement to the world?
Do DRAW statements make you break out
in hives? Well then, maybe Fontgen from
JR & JR Softstuff is what you need.

Fontgen is a collection of screen dis-
play fonts, icons and borders that can be
used to replace or supplement the standard
CoCo 3 BASIC Hi-Res graphic font. It
comes packaged with a font editor, a
machine language subroutine used to load
four fonts at one time, BASIC subroutines
to print the larger-than-standard fonts
(including icons and borders) and a demo
program.

The package takes advantage of the
fact that the Hi-Res display font (and the
rest of BASIC) resides in RAM. Standard
size fonts replace the Tandy-provided font
on a one-to-one basis. Larger fonts, icons
and borders require multiple positions to
store a character. For example, "Bigfont"
requires nine characters in a three-by-three
group to form one Bigfont letter. For this

reason, the Bigfont alphabet is stored across
three font datasets, which makes the abil-
ity to have more than one font in memory
important.

The supplied font editor allows you to
create or edit standard fonts in an eight-by-
eight matrix. The larger fonts require plan-
ning because only part of the character
(eight-by-eight out of 24-by-24) is avail-
able for editing at a time and is thus harder
to visualize. Except for overly sensitive
cursor keys, the program works as it should.
Functions are provided to aid in creating or
modifying character fonts. While some of
the functions may be a little confusing to
those of us used to paint programs ("Ro-
tate" shifts and "Mirror" flips), they are
useful.

The font editor also has a function to
allow you to manipulate the palette. It
allows you to set the color in the 16 palette
cells to any one of the 64 available colors.
You can then save your selections as BASIC
statements to be included in your own
program. This feature is nice but seems to
me to be only distantly related to fonts.

The standard size fonts can be used
directly with HPRINT by loading them
into memory, but the large fonts (includ-
ing icons and borders) require special
methods to display. JR & JR Softstuff
provides BASIC subroutines that can be
used to print these larger characters. You
can also use them as examples to write
your own routines, if you prefer.

For the large fonts, or if you want to use
multiple fonts without a lot of disk access,
a machine language program is provided
to store up to four font datasets in memory
at one time. Your BASIC program trans-
fers the fonts back and forth in memory via
DEFUSR calls.

All in all, the package is fairly easy to
use and the program easy to follow. This is
fortunate because the documentation is

not. I received a dozen loose sheets of
paper, printed on both sides. Except for the
cover, there are no graphics or illustra-
tions. Details that would have been easy to
pick out in a table are buried in the text.
Indentation is nonexistent, and no index is
provided. The best that can be said is that
most of the information you need is there.
You just have to dig it out.

M H M it

Even so, if you would like to spice up
your Hi-Res displays, the package will
save you some time, and the price won't
break you. However, if you're just starting
out in programming, some of the features
may have to wait until you have a little
more experience.

I had no major problems with Fontgen,
but JR & JR Softstuff does provide a
number for technical assistance. No hours
are listed, but I did reach the order number
Saturday afternoon. You pay for any calls
you make.

Fontgen requires a Color Computer 3
with 128K and at least one disk drive. The
package will work with a TV or a compos-
ite monitor, but you won't be pleased with
the results. An RGB monitor is a much
better choice.

Get your modem to work

with OS-9 Level II for under $20

The Forgotten Chip

By Carl Austin Bennett

While a Serial I/O port appears
on the back of every CoCo, it
appears to be unusable in any
OS-9 communication program. It is
suited only to use with a serial printer;
a modem connected to it is not even
usable with Radio Shack's own Desk-
Mate 3 software.

Radio Shack suggested a Multi-raK
interface and a Deluxe RS-232 Pak as
a suitable replacement for the "bit-
banger." Although this entailed a cost
quite a bit higher than the CoCo 3
modifications I am about to describe, it
did offer a second serial port. Unfortu-
nately, both of these items have been
discontinued. Some alternatives to the
RS-232 Pak are offered by CRC Com-
puters in Montreal, but these require
either a Multi-Pak or a Disto Super
Controller.

Unless you need two serial ports, it
may be more economical to upgrade the
existing serial interface for OS-9 oper-
ation. Only one chip, a crystal, two

- ' ' — ■

Car/ /4. Bennett is an electrical engineer-
ing student from Kingston, Ontario. He
owns a 512K CoCo 3 with a 1200-baud
modem, a modified electronic typewri-
ter as a printer, and OS-9 Level II. He
also once had the misfortune of having
to write a terminal program using the
infamous "bit-banger" serial port.

diodes and a resistor are required. You
must make 22 connections to the CoCo
3 printed circuit board. Some electron-
ics experience helps, and the project can
be completed in one weekend for under
$20. Only one byte of the OS-9 Boot file
needs to be changed to make this chip
operate with any OS-9 program, and
existing commands such as PRINT 8-2
(in Disk BASIC) are not affected in any
way.

All of these upgrades use a special
chip to convert the information being
sent from the parallel format (eight bits
at a time) used by the 6809 to a serial
format (in which all bits are sent, one
at a time on a single wire). This chip is
the Rockwell R6551 Asynchronous
Communication Interface Adapter,
described in more detail in Turn of the
Screw — All About Serial Packs by
Tony DeStefano (RAINBOW, August
'88) or in data sheets published by the
manufacturer. It is capable of sending
and receiving data at up to 19,200 bits
per second (19,200 bits of transmitted
data is equivalent to one full 80-by-24
text screen).

OS-9 already contains the instruc-
tions needed to make this chip work (the
flCIPPPK driver and /t2 descriptor). It
need only be told where the chip is
located. This is done by using the
Modpatch command to change one byte
of /t2. At the OS-9 prompt, type:

modpatch /t2
c 10 68 30

Press CTRL-BREAK to end the process.
The change can then be saved to a new
disk using Cobbler (described in the
OS-9 Level II manual).

That's the easy part — now some-
thing more difficult: the task of adding
the 655 1 chip to the computer. All of the
usual warnings apply here: Precautions
must be taken against damage due to
static electricity; any modification to
the computer will void the Radio Shack
warranty; some errors in construction
may damage your computer or cause
the system to crash; all connections
should be verified before applying
power; and an ohmmeter should be
used to check for short circuits.

Also, all connections and measure-
ments must be made with the power
disconnected. Reversal of the power
leads or connection of any lead to
voltages less than zero or more than five
volts will destroy the chip. While this
modification has been tested in a CoCo
3 and works fine, there is no guarantee
if you choose to use information con-
tained in the article.

The 655 1 works best placed in a 28-
pin socket on a small circuit-board of
its own. The crystal should be placed
near 6551 pins 6 and 7; the diodes and
resistor are best placed near Pin 10. The
board may be hidden in the space
underneath the CoCo 3 keyboard. It
may be best to wait until all connections
are made (and correct operation of the
CoCo 3 observed) before plugging in
the 6551.

Sixteen connections are made to the

130

THE RAINBOW May 1989

underside of the expansion connector
(at the right-hand side of the computer).
These are shown in Figure 1 .

As these connection points are spaced
relatively closely, it may be best to make
the connections using a 4- or 8-
conductor ribbon cable of relatively
small size, to make the connections to
the expansion connector before making
the connections to the 6551, and to deal
with all connections to odd-numbered
pins first. After making the first eight
connections, verify proper operation
(i.e., no short circuits and the computer
working normally) before proceeding
with the remaining eight. This makes
location of any mistakes much easier.

Once these 16 connections have been
made and verified, there are six more
connections to make to the computer.
These are:

1) from Pin 4 (Receive Data) on ICR
(the 77527 SALT chip, on the lower left
corner of the CoCo 3 circuit board) to
Pin 12 of the 6551.

2) from Pin 5 (Carrier Detect) on IC8
(SALT) to Pin 16 of the 6551.

3) from Pin 6 (Transmit Data) on IC8
(SALT) to the anodes of the two diodes
(1N4148) and to one side of the 10K
resistor connected to +5 volts.

4) the previously-existing connection
from IC4 (68B21 PI A) Pin 3 to IC8
(SALT) Pin 6 must be removed —
connect IC4 Pin 3 to the cathode of one
of the diodes. Connect the cathode of
the other diode to Pin 10 (Transmit
Data) of the 651.

5) from Pin 12 (*Chip Select) of IC9
(74LS138 Address Decoder — located
near the ACVC [Advanced Color Video
Chip]) to Pin 3 of the 6551.

6) from Pin 3 (*Int) of the CPU (IC1 —
68B09E, or Pin 37 or 38 of the
LSC81001 PIA [IC5]) to Pin 26 (♦Inter-
rupt Request) of the 6551.

A 1.8432 MHz crystal is to be con-
nected directly to pins 6 and 7 of the
6551 chip. At this point, the circuit is
ready to be tested.

Making a Serial Cable for the CoCo 3

To connect the serial port of your
computer to a modem, a four-wire cable
is needed. This cable may be made from
several feet of telephone wire with a 4-
pin DIN connector (Radio Shack Cat.
No. 274-007) on one end and a DB25
connector (Radio Shack Cat. No. 256-
1547) on the other.

Note that the cable for use with
modem may not be the same as that
used with a serial printer. For a modem,

1) Connect Pin 1 (Carrier Detect) on
the computer to Pin 8 on the modem.

2) Connect Pin 2 (Receive Data) on the

Testing This Circuit

Due to the risk of creating a short
circuit between neighboring data or
address lines, it is best to check for such
errors at various intervals during the
construction of this circuit. An ohmme-
ter will quickly detect any pairs of
adjacent pins that may be shorted to
each other. Any short circuit in the
system bus lines will also cause a screen-
ful of garbage to appear instead of the
Super Extended Color BASIC message if
you attempt to use the computer. The
655 1 need not be plugged in to check for
either shorts or continued system oper-
ation — the computer will start without
it. If you are unable to obtain normal
operation with the 6551 socket empty,
recheck your connections (a good idea
in any case) and check for short circuits.

If all connections are in place and
verified (with the system operating
normally), you are ready to plug in the
6551. The pins of a new chip will gener-
ally need to be bent slightly inward
before the chip can be plugged into its
socket. The edge of a tabletop works
well for this. Once the 6551 is in place,
software may be use to check for proper
operation.

If OS-9 is able to use the serial port
at this point, the project is complete. If
not (with the computer working), there
are some simple tests that may be run
under Disk BASIC.

The simplest (if your modem has
"send data" and "receive data" indica-
tors) is to turn on these indicators using

POKE 65330,12. Use POKE 65330,0 to

turn them off. If this does not give
consistent results, one of the connec-
tions to the address, data or control
lines may be at fault. (See Figure 2.)

If this works, the eight connections to
the data bus may be verified by running
a program such as FOR 1=0 TO 255: POKE

65331 , I : PRINT PEEK ( 65331 ): NEXT,

which will print numbers 0 through 255
if the 6551 is connected.

If the 6551 will transmit but will not
receive, check both the receive data and
carrier detect signals. If carrier detect is
not active, all received data is ignored.

If the 6551 registers (as displayed by

PRINT PEEK(6532B); PEEI<(65329);
PEEK(G5330); PEEK(G5331)) all appear

to contain 255, then recheck the chip
select inputs (pins 2 and 3 on the 6551).

Theory of Operation

Assume that a user, while running a
computer communication program,
presses the A key. What happens?

The computer, after scanning the
keyboard, finds a key pressed and
represents this by a number (A becomes
97, or 01 100001 in binary). It must then
send this information to another com-
puter. A telephone line (or any serial
link) cannot send eight Is or 0s simul-
taneously — but it can send one bit of
information at a time — a one or a zero.

When there is information to send, it
sends a zero to indicate the start of one
character of transmitted information. It
then must send eight Is or 0s represent-

ing the information being sent, one at
a time, with the far right one being sent
first. Each of these must be present for
a constant and minimum length of time,
as modems can only go so quickly. It
then sends a 1 to indicate that it has
finished sending this character. For a
2400-baud modem, all of this must
occur within 1/240 of a second. But the
computer has more to do than simply
send information.

If your CoCo is sending data to
another computer, it is very likely that
the other computer is immediately
sending this information back, so that
it will appear on your screen. You must
therefore be able to transmit and receive
information at the same time, and (as
if that weren't enough) if you're using
OS-9, you may want to run other pro-
grams while you're sending and receiv-
ing characters. The "bit-banger" Serial
I/O port requires that the program

1 34 THE RAINBOW May 1 989

individually wait for and handle each
one or zero being sent or received — at
some point, it just doesn't have time to
do all of this.

This is where a chip like the 6551
comes in. A program need only tell it
how many bits of information to send
(and at which speed), check to see that
it's ready, then give it all eight Is and
Os at the same time. The 6551 takes care
of the rest. It can send and receive
information at the same times, and it
leaves the computer free to do other
things while a character is being sent.
When nothing is available to be sent, it
simply sends Is.

The 655 1 looks like four locations of
memory to the computer, but which
four? The computer can find this out by
looking in the /t2 module, which it
reads from disk when you type DOS.
The 6551 also needs a signal (Chip
Select) to tell it that information is
intended for it and not for another part
of memory. A Multi-Pak Interface can
provide a circuit to separate informa-
tion intended for the disk-drive con-
troller from that intended for the RS-
232 Pak or some other cartridge. In the
CoCo 3, however, there already exists
a signal (not currently used for any-

thing) that can be used to serve much
the same purpose. By using this signal
(and by putting the 6551 inside the
computer itself), no Multi-Pak is re-
quired, reducing costs considerably.

Also, the RS-232 standard requires
that +5 or + 1 2 volts be used to represent
a zero, and -5 or -12 volts be used to
represent a one. These voltages cannot
be connected directly to the 6551 with-
out damaging it. They must instead be
changed to levels that the 6551 can use
directly: 0 volts for a 0, 5 volts for a 1.
Any serial port that plugs into the
expansion slot must contain extra chips
to convert between these two sets of
voltages. In the CoCo 3, the SALT
(Supply And Level Translator) chip
already performs this function, along
with other functions related to the
cassette recorder and the power supply.
SALT is already being used by the
existing bit-banger port, but it is quite
possible to upgrade to the 6551 chip
while leaving the existing port in oper-
ating condition. The inputs to the 6551
can be directly connected to their coun-
terparts in the existing circuit without
any problems. The output (Transmit
Data) must be treated a little differently,
so that no harm occurs if the 6551 tries

to send a zero while the bit-banger is
trying to send a one. This is the purpose
of the resistor and diodes. A zero from
the 6551 causes a diode to conduct,
sending a zero to the SALT chip. A zero
from the existing output has the same
effect. If neither chip is active, the
resistor pulls the input to the SALT chip
high, causing ones to be sent. The
operation is the same as that of an AND
gate.

By using these existing circuits, this
modification provides access to a
higher-speed serial port with one chip
(the 6551 itself) at a cost of under $20.
Software written for the existing bit-
banger serial port (such as Disk BASIC)
operates as if the modification were not
even present, while this does not pro-
vide a system with two serial ports, it
offers most (if not all) of the other
benefits of an improved serial interface
for OS-9.

Using Hardware, Bypassing Software

B / own a CoCo 3, Multi-Pak, two

problem: I like the ability to use a
modem and a printer at the same time,
but the 32-character screen width used
by the RS-232 Pak is less than adequate
for most host systems, especially with
the 40- and 80-character screen availa-
ble with the CoCo 3 software. Is there
communications software available
that uses the 40- and 80-character
screens and the RS-232 's hardware
while bypassing its software, or is there
a way to burn a software package into
an EPROM and replace the Pak's
software chip? I have also had a prob-
lem while attempting to download using
the Pak. Most BBSs I have used require

a carriage return to start the download,
but when I set the Pak for downloading
and press the BREAK key, I can no

T) The 300-baud DCM-6 connects to
/C a serial port, not the cartridge
expansion port. It can be connected
with a 4-pin DIN to DB25 cable. The
pin connections for the serial port on
the back of the color computer (clock-
wise from the notch) are:

Pin 1 CD
Pin 2 RS-232 In
Pin 3 Ground
Pin 4 RS-232 Out

To make the four- wire cable, connect
Pin 1 to Pin 1 on the DB25, Pin 2 to
Pin 2 on the DB25, Pin 3 to Pin 7 on
the DB25, and Pin 4 to Pin 3 on the
DB25. On the DB25 end, also wire pins
4, 5 and 8 together and wire pins 6 and

Scattered Pokes and Patches

Recently I bought the program ED-
TASM+ and would like to switch it
over to disk but find that the pokes
and patches necessary seem to be scat-
tered over a number of different RAIN-
BOW issues that I unfortunately don't
have. I wonder if you could reprint
those pokes with detailed instructions
on how to implement them. Having a
CoCo 3, I would also like to use the
patch for an 80-column screen in your
column of January '88 by Roger
Krupski, providing it is compatible with
EDTASM+ as well as Disk EDTASM.

Also, in trying to copy the program
tptodsk in the February '87 issue, Page
73, using EDTASM+, / get a missing
operand error in Line 277, which is a
routine for checking for the version
(either 1.0 or I.I) of ROM. Because of
the CoCo 3 version I suspect this may
be the problem. Being a novice in
assembly language, I wonder if you
could suggest a way around this if you
also believe it may be the cause.

THE RAINBOW May 1989

O When the CoCo 3 copies the
ROM code to RAM on boot up,
one of the things it does is change the
1 on the sign-on screen of the Disk
BASIC ROM 1.0 or 1.1 to a 2. These are
the only ROMs ever sold by Tandy. The
patches you desire are too extensive for
a column of this type. THE rainbow
offers article reprints for $2 each, even
if the magazine is out of print. RAINBOW-
ON-TAPE/DISK is also available.

Out of Characters

/ have a Co Co 3 with 512K, one
DSDD drive, CM-8 monitor, a
CGP-220 printer, OS-9 and Multi-
Vue. / also own an Amiga 500 with a
VTI00 emulation package. This setup
works well and I have used it success-
fully with many host systems. My prob-
lem is that I cannot receive characters
through the RS-232's port from the
Amiga; the moment I type tsmon /tl,
my Co Co aborts and responds to no-
thing except the CLEAR key, which still
changes me between windows (if I have
any open). I can output data at any
speed (300 to 9600 Baud) with no prob-
lem by typing dir/tl. This works fine
at any speed, but I read in the Complete
OS-9 Guide that the terminals accessing
OS-9 through the internal RS-232 port
should have a baud of 300. I have tried
it at 300 baud but it still doesn I work.
If I type build afile <'tl, the CoCo
also stops. And when the CoCo stops,
even on the previous command where
only the input is redirected, periods are
sent out the RS-232 and are displayed
on the Amiga screen. All the above still
happens even if I have no cable con-
nected to the CoCos RS-232 port. I
have also tried this on my brothers
CoCo 3 (I28K) with the rest of the
system configuration the same, with the
same results. Is there a problem with my
hardware setup, the serial driver or
what? Also, I purchased Multi-Vue
because it advertised that Multi-Vue
can be used to create user-friendly
interfaces for your developed programs,
but after opening the package (and
therefore voiding any chance of return-
ing it), I find that this is not the case
because there are no tools for creating
ICONs. Can you suggest a way I can
create my own (< user-friendly " interface
ICONs?

13 The port ftl in OS-9 Level II is
/C unsuitable for two-way commun-
ication since it accesses the CoCo 3's bit-

banger serial port, which was designed
for printers. To connect two computers
for communication, you need a hard-
ware serial port like the one supplied in
Tandy's Deluxe RS-232 Pak or one of
its clones. A number of mouse-based
icon editors have been posted on the
Delphi OS-9 SIG. To date, none of the

by one can be purchased by mail.

Mods on Delphi

I own a CoCo 3, FD-500 disk drive
and OS-9 Level II. I am planning to
purchase an upgraded Multi-Pak
interface and an Owl-Ware 3 l /2'inch
drive. Do you know where I could get
a driver for the 3V2~inch drive to run it
under OS-9? Will OS-9 know if I have
my FD-500 drive in one slot of the
Multi-Pak and the other drive in
another slot? How can I use my Radio
Shack Speech /Sound Pak under OS-9?

Don Vaillancourt
Mississauga, Ontario

T) A 720K 3!/ 2 -inch drive is electri-
A X cally equivalent to a 720K 80-
track DSDD 5 ! /rinch drive, for which
OS-9 Level II includes a device descrip-
tor in the modules directory. Both 314-
inch drives and 5!4-inch drives can
share a common controller, so only one
Multi-Pak slot would be used. To enable
a Speech/ Sound Pak to work with OS-
9 Level II requires replacement of one
transistor. You will also need new soft-
ware drivers. Both the drivers and the
hardware mods are posted on Delphi.
At the moment, I know of no other
source.

Unfamiliar Codes

with OS-9 to tell my printer to print

nize the codes. What can I do?

While nothing can be done with
X the built-in modem, some elec-

The resulting RS-232 Pak is then used
with an external modem with baud rates

Get5tt(suscall($BD)), but a function

of SetStt. Correct this before proced-
ing with this article's instructions.

Before we go any further, here's what
SS.fipGPB does: It passes variables
through what are commonly called Ge f
Put buffers, using the BASIC09 routine
Syscall. What does that mean? Well,
for starters, Get /Put buffers are areas in
memory that OS-9 Level II usually uses
for defining fonts and graphics pointers
patterns and getting areas of a graphics
screen. For example, with Gfx2, to use
GET like the BASIC command GET, you
have to give a group and buffer number.
The group number can be anything

Philip Brown is 17 years old, and has
been programming for seven years. He
has learned LOGO and has taught
himself OS-9 Level th BASIC, BASIC09
and Assembly language.

from 1 to 199. The operating system
itself uses the others. The group number
puts aside an 8K block for your use,
which you then have to give a buffer
number. This buffer is a subdivision of
that block. It can be any size, from one
to two bytes, to almost the entire 8K.

The reason I say almost is because the
system uses 32 bytes per buffer in the 8K
block to define size. There are only
sixty-four 8K blocks in 512K of mem-
ory. The system brings one into exist-
ence and permanently determines the
size of the buffer(s) whenever you load
a font, pattern or an area of a graphics
screen. That means, if you want to store
a greater amount of material, you have
to kill the buffer (Gfx2("killbuf f"))
before attempting to get anything
bigger. Alternately, you can define the
size of the buffer before you start to do
anything with Gfx2( "defbuf f Re-
member also that this is system-wide. If
you continually do this and don't kill
them afterwards, you will lose memory
(8K block per group) without realizing
it.

An alternate method is using Display
with the codes listed in the windowing
section in the Level II manual. Most of
it is very comprehensible. For a detailed
look at Get /Put buffers, read pages 3-

7 to 3-8, DfnGPBuf (define Get/Put
buffer).

Now the hard part — Syscall. Sys-
call is an incredibly useful function. 1
advise merging it. with BASIC09, if you
haven't already (then attr basic89 E
PE). You can do things in Level II that
you cannot do any other way. It calls for
various OS-9 machine language sub-
routines, but don't worry: The proce-
dure is simple once you understand it.

There are about 90 system calls listed
in the technical reference under System
Calls (Chapter 8). Most of them are too
technical for easy use — two that can
be used often are Get Status and Set
Status (GetStt and Setstt).. They are
really a compilation of smaller subrou-
tines, listed on pages 8-112 through 8-
1 50. All these subroutines are listed with
55.--, the -- being the actual name of
the subroutine.

The line of demarcation between
GetStt and Setstt routines is 8-131.
As noted above, the subroutine
SS„MpGPB(map Get'Put buffer) is on the
wrong side of that line. When you are
looking through them, it is important to
note which side you are on because
some of the function codes are the same
but do different things under GetStt

and Setstt. For instance, Function 88
under GetStt reads 32 bytes of informa-
tion from a "path descriptor," whereas
Function 80, under Setstt, writes 32
bytes of information. Therefore, SetStt
Function 80 could crash a window, a
disk drive, a hard drive, or the whole
system. I lost count of the times I was
experimenting, and suddenly the screen
went haywire while everything locked
up system-wide.

Get Status generally only reads the
status of something, whereas Set Status
changes it. So Setstt is the one to watch
out for. As long as you are careful, you
should be all right. But save everything
you are working on at least once every
half hour.

In using Sysca 11, first define a special
variable type. Syscall is expecting
information in that format. The stand-
ard way to use it, according to the
section in BASIC09's manual is: Type
registers=cc,a, b,dp:byte; x,y,u:
integer DIM regs: registers.

The cc,a,b . , etc., stand for some
of the different data registers in the 6809
chip. Once you have defined the varia-
ble type, load it with the data asked for
by the system call you wish to make,

e.g.: regs.a=l\regs.b=$B3. How do

you know what to put in? Here's a
specific example (F$SUser Page 8-39,
technical reference): If you want a user
ID of 4, use:

regs . y=4

RUN Syscall ($lc, regs)

The $1C tells Syscall to execute
F$SUser. The $1C comes from FSSUser
I03f lc at the top of page 8-39. The I03f
is a machine language 5WI2 instruction
you can ignore since you are using
Syscall. After running Syscall,
regs.b gives the code of any errors,
regs.cc is the Condition Code register,
which involves a knowledge of machine
language.

To get to Get Status, or ISGetStt
(page 8-54), requires a path number to
be in Register A and the function code
in Register B. Because of using
SS.MpGPB, regs. a can be zero and
regs.b=$84. Additional entry condi-
tions are given by 5S.MpGP8 (Page 8-
122): x must have the group number and
buffer number of a G/P buffer, and y
must have 1 or 0, telling whether we
want to map or unmap. If mapping it,
regs.x will have a memory location as
the start of the buffer, and regs.y tells

how long it is. You can then poke it to
your heart's content.

In mapping the system makes a copy
of the actual buffer into an area your
program can access. Then whatever you
do to that area will be done to the
original until you unmap it.

This sample program is simple, its
purpose being only to show that the
method works. The "core" either prints,
modifies and prints, or just modifies the
appropriate buffer. This procedure is
ideal for forking one main program
with another and exchanging data.

Shell basic09 prog(tt)& is one way,

where 8 is the group buffer number and
prog is a packed program in the execu-
tion directory.

As a reminder, the workhorse for
these programs is ss.MpGPB, of Sets tt.
The value of regs . x before the call is the
group number (anything from 1 to 200)
*25G +, the actual buffer number. After
the call, the value of regs.x tells where
the buffer has been copied to. You can
then peek and poke those locations
freely.

An interesting point on how powerful
the procedure is as a tool is that after
I perfected this method, 1 came across
a reference stating that the system itself
uses Buffer Group #0 to keep track of
error messages (you cannot map the
same buffer into the user space twice).
This means that if the program has an
error in the middle, you have to run
unmap before trying it again. Then run
l<ill_buff when you've finished with
the buffer (8K).

And now directions to the most
powerful BAS1C09 programming tool
since Syscall:

Given are two listings, Core and
Start. Type very carefully to avoid a
total system crash of OS-9. Rebooting
is a pain, so if you can spare the mem-
ory, keep the main / term window run-
ning to get out of minor messes and
operate from windows I and 2. Forget
about compiling your pet program at
the same time, though.

First merge BASIC09, Syscall and
Gfx2 into one file, attrepe the new file,
and load it. Gf x2 isn't strictly necessary
using Syscall, but it makes things
simpler. Type in the first listing, Core,
and save* it. Then get back to the OS-
9 level, build Listing 2, and start and
execute it (or type it in directly). Get
into BASIC09 and load Core. Then clear
and load it on Window I. Run def-
_buf f . Next, edit Core until it becomes
Core 2. This involves deleting the line
with run mod_buf f . You can do it on the
other window since the buffer can be

modified by either program. Now run
Core on both windows. The one without
the run modJDuff is now subordinate
because all it does is simply read the
other's information.

Switch to the one you left alone, and
pause it. The numbers on the other
window will not change because the
modJDuf f program has been paused on
the dominant window. If you want,
retype the line you erased in the subor-
dinate window and delete it in the
dominant window, then run both. The

flow of information is reversed, but it
doesn't have to be just one way. You can
have each work on its own separate part
of the buffer. Each can have different
buffer numbers to work on, also but
with the same group number.

This may sound like a lot of trouble,
but it's not. Once going, it will never
screw up again unless something else
uses the same group and buffer number,
A way around this is to use the original
process's ID number for a group
number using Syscall, although it's

The applications are limitless. I'm
going to use it in a game to keep the
character-handling routines separate
from the monsters, so the player doesn't
slow down when a lot of monsters are
on the screen. Another use is for a split-
screen or multiterminal, real-time game
so you don't have to wait while your
opponent refuels or whatever. The
buffer can be any length (to a little
under 8K). It's a whole new super
variable type. Work with it carefully,
until the basics are down. See what you
can come up with.

MLBASIC 2.0 - BASIC Compiler

If you want your BASIC programs to run up to 50 times faster, or want more
programming features without learning another language, MLBASIC is for you.

MLBASIC is the most compatible BASIC compiler available for the Color Com-
puter. WHY? Because MLBASIC fully supports:

- Low- and high-resolution graphics
-All types of I/O (disk, screen, printer, RS23S)

- All available commands offered with BASIC
- Floating point functions and expressions

- Integer, floating point and string type variables and arrays

- Use of all available 5 1 2K RAM in the COCO 3

- 80,40 or 32 column text displays

MLBASIC not only contains everything that you would expect a BASIC pro-
gramming language should contain, MLBASIC has features that offer flexibility
of other languages like C, Pascal, FORTRAN and even assembly language. These
features will allow programmers to directly access the CPU registers on the
COCO, produce modular program code with SUBROUTINES, manipulate memory
in blocks, and even call ROM routines in other areas of memory.

MLBASIC revision 2.0 has incorporated all enhancements that were
suggested by MLBASIC 1.0 users and more. Revision 2.0 did away with all the In-
compatibility problems that existed with revision 1.0.

MLBASIC allows for the first time user to quickly compile a program using
default compiler settings. The advanced user has the capability of controlling
over a dozen settings which control where the program is compiled, which
medium to compile to (memory or disk), string space, compiler listings and
more.

With all this going for M LBASIC, your might expect the cost to be a little out
of your budget. After looking at prices of other BASIC compilers for the COCO 3
you might be correct. But look again at this ad; for only $59.95, you can have a
programming language that will spark your interest once again in the COCO.

Before you buy another BASIC compiler for the COCO, find out if it supports
everything MLBASIC supports. Then look at the price tag. We feel that it won't be
long before you place an order for MLBASIC.

CoCo Consultations

That's One Great Chip!

I have an old Multi-Pak (Cat No. 26-
3024) and the upgrade PAL chip for it.
I also own both CoCo Is and 3s. Can
I upgrade the Multi-Pak in such a
fashion that it will work with both the
older and the newer Color Computers
that I own?

Also, can you tell me what the
jumpers on a Tandon TM-100 series
drive do, so I can set them to use the
drive with my CoCo?

David Johnstone
Torrington, Connecticut

After you install the upgrade PAL
chip in your Multi-Pak, it will work fine
with the RS-232 pak, disk controller,
and all other currently sold cards that
plug into the Multi-Pak, regardless of
what model CoCo you have. However,
if you want to use CoCo Max II y the old
PBJ Word Pak Model I or II, or other
older pieces of hardware, you need to
buy a PAL switcher from Microcom to
allow you to switch back to the older
PAL chip.

As far as the jumpers on a Tandon
TM-100, its 16-pin socket for drive
select jumpers has an assignment of pins
to functions as follows:

1 — 16 HS (not used).

2 — 15 Drive Select 0.
3—14 Drive Select 1.
4 — 13 Drive Select 2.
5—12 Drive Select 3.

6 — 11 Multiplex (don't use).

7 — 10 Spare (don't use).

8 — 9 HM (not used).

Only a single jumper in the correct
drive select position is needed to make
the drive work with a CoCo. Of course,
you must also have one and only one
terminator resistor pak in your drive
system. That is, the other socket on the
drive must have a terminator resistor
pak in it if none of the other drives on
that cable have one, or (if you are
adding the drive to a system that already

has drives on it) you must remove the

socket before adding the drive to the
system.

Mount Fujitsu

Where can I get the screws used to
mount Fujitsu half-height drives in an
FD-501 case?

Scott McCall
Jacksonville, Florida

You need to specify what kind of
screws are required. I will assume that
the particular drive you are asking
about uses metric screws, probably
standard 3 millimeter type. Any decent
hardware store stocks various sizes of
metric screws.

As an alternative, you can use a tap
to convert the holes in the drive which
makes it possible to use American S AE
type 6-32 screws.

Keep Plugging Away

Vm tired of plugging and unplugging
ROM paks from my disk-based Color
Computer. How can I copy them to disk
and run them off my disk system?

Geoff Hall
Casselberry, Florida

I have been asked this question liter-
ally hundreds of times. I have also
helped fix literally dozens of computers
that were burned out by folks who
carelessly unplugged a disk controller
or ROM pak while the power was on.
So your question is certainly a pressing
and legitimate one. The other side of the
coin is that makers of ROM paks want
to discourage privacy, and so use the
fact that their program is in a ROM to
try to physically prevent making copies.
This is especially true of the most recent
releases of ROM pak game software
from Tandy, which tend to be heavily
protected against running a RAM en-
vironment. The older ROM paks can be
copied to and run from disk using a
program called Multi-Pak Crack, plus
added patches. The program may be
available from Microcom or Second
City Software. But the new version of
the program cannot be effectively cop-
ied to and run from the disk.

Phone Home CoCo

I need to know the addresses used by
various Co Co hardware paks to aid me
in choosing an address for a hardware
project.

Winston Pike
Escanaba, Michigan

Currently I don't have a complete
updated table of such addresses. The
information is constantly changing as
new paks are added and others become
obsolete. I suggest making the project
in such a way that you can, by moving
jumpers or changing trace cuts, re-
address the project's ports to accommo-
date a range of two or three ports. You
can also design the device to use the
SCS line to decode its addresses, plac-
ing it in the $FF50 to $FF5F range. This
requires using a slot-dependent device
with a Multi-Pak.

Consider whether or not the project
is likely to be used on a system with, say,
a Speech/ Sound pak. If not, then don't
worry about address conflicts. A partial
list of addresses used by popularly
available paks is as follows:

SFF60 Tandy X-Pad (obso-

— SFF63 lete and rare . . . con-

sider that space avail-
able!).
SFF64 Free (?).

from Delphi or buy utility programs to
help you with this. Those guys who pop
up on the screen during cold starts
wrote the patches to the old CoCo
BASIC to make it work on the CoCo 3.
Delphi users call them the Three Mug-
ateers, among other things.

The story goes that a group of pro-
grammers put the picture in without
Tandy knowing it until moments before
the ROM was mass produced. Faced
with the choice of either further delay-
ing the release of CoCo 3 or leaving it
in, Tandy chose to leave it in. The
picture takes up a full 6K of space in the
CoCo 3's Extended BASIC ROM, which
is more than enough space for saving
Hi-Res picture screens, a full screen
editor in BASIC, and much more. In-
stead, we have a not-so-lovely picture.

An Ideal Picture

I'm thinking of marketing a product
and service that will allow users to
customize their CoCo 3 BASIC ROM by
having their picture (not that of Micro-
ware) appear on the screen when they

hit control - ALT - RESET. However,
as you know, this involves replacing the
28-pin ROM chip in the CoCo, which
is soldered into the CoCo 3 circuit
board. Is there any way to disable the
chip without actually removing the
mother board and desoldering the chip?

David Barnes
Second City Software
Chicago, Illinois

Yes! All you need do is have your
customer clip Pin 20 of the ROM on the
CoCo and solder to the stump of the pin
as it enters the chip, a IK pull-up
resistor that goes to +5 volts. That will
disable the ROM in the CoCo. Then,
you simply piggy-back on the new
EPROM, and carefully wire the pad
previously used with Pin 20 of the old
ROM to Pin 20 of the new one, which
you have bent out. Now, while doing
this is much easier and safer than
desoldering the entire ROM chip, the
task can still be difficult for some
people. Good Luck!

A Printer of a Different Color

I have a Quadjet QJ-9000 color print-
er, which is similar to the Canon PJ-
1080a and CGP-220 printer. But its
colors appear to be set differently from
the way the colors are set using the
CGP-220. Can I set its DIP switches to
make it work like a CGP-220?

John H. Opheim
Burlington, Kansas

There were almost a dozen varient
printers made around the Canon four-
color-ink jet printer mechanism. Unfor-
tunately, all of them use slightly differ-
ent on-board ROM software, and the
codes for setting colors varies signifi-
cantly among different printers in that
family. You need to experiment with the
codes to find correct ones for your
printer. As for setting DIP switches, I
have no way of knowing without the
documentation for that printer. Do you
have it?

Switching Switches Not Good

/ am having trouble using a ROM
switcher on DOS ROM chips. Is there
a difference between Color BASIC and
DOS ROMs?

Robert Vernon
College Station, Texas

The 24-pin ROMs used in older
CoCo Is and 2s and in all disk con-
trollers up until the FD-502 controller •

system are electrically the same. These
are 8K-by-8 chips compatible with the
(now no longer made) Motorola 67866
and 68764 EPROMs. The 28-pin ROM
used in the later model CoCo 2s and
current CoCo 3s are electrically differ-
ent. Actually, making a ROM switcher
that switches between two different
ROMs is not a good idea. Today, with
16K-by-8, 32K-by-8 and 64K-by-8
EPROMs so inexpensive and widely
available, the best way to switch be-
tween two varient ROMs is to burn
them into the same bigger EPROM,
then send +5v or ground the high order
address lines in a way that appropriately
selects which 8K, 16K or 32K band on
the ROM will be active. This approach
costs less, takes up less space and uses
less power. Old physical ROM
switchers are now obsolete, previously
used when big size EPROMs were
either unavailable or too expensive.

Add, Supply and Remove

How can I use an IBM disk drive on
my Color Computer?

Ron Cank
Missouri City, Texas

With a 180K or 360K type drive, an
IBM disk drive works easily on a Color
Computer. A 720K or 1.2 megabyte
drive, however, would probably not
work.

To add the drive to your existing
cable, merely add a connector to the
cable, and supply the drive with its
required power (+5 volts at .3 amps and
+ 12 volts at .6 amps) from any appro-
priate power supply. Also, be sure to
remove the terminator resistor from the
drive (if it has one) and select the
jumpers to indicate what drive number
you want. IBM's are used as Drive 1 by
most CoCo users.

Chown

By Evan Robinson

The program Chown was modeled
after a program on an Altos
UNIX System V machine. It
provides a way of giving other users on
your system files. I found the need to
write this when a number of my users
wanted ownership to some test files I
had downloaded from systems they had
no accounts on (primarily because the
boards I called were long-distance).

What this program does is simple.
When you execute it, it searches the
argv vector for two strings. If not
found, the usage form is displayed.
After this, it converts the User ID
supplied in the first argument to an
integer via the atoi ( ) function. Then it
passes the filename and new User ID to
the choun ( ) call. If an error is detected
for any reason (the file is a directory file
or cannot be accessed), it aborts with a
message.

The only real problems I have en-
countered is that only the superuser of
the system (UID 0) can change owner-
ship. Not a big problem, but it does
differentiate from the UNIX equivalent
that allows user-to-user chowning.

I recently received as gifts both OS-
9 and a disk drive. I upgraded the
system with a second drive and was
given my own telephone line (I made so

can handle concurrent processes. Give

UNIX in June and must say it is great.

For avid OS-9 users, Chown makes
adaptation beautiful.

More BASIC09
Programming

By Richard A. White

Rainbow Contributing Editor

Last issue, we began a discussion of
a BASIC09 program to enter and
analyze data from a small local

survey. While the program is not some-
thing many people will have a use for,
it does provide good illustrations of
BAS1C09 programming that will help
people to write their own. Whether you
use a programming language, spread-
sheet program, a database manager or
some more specialized piece of soft-
ware, you need to give the computer
exact details of what you want to do.
This is programming.

For a general programming lan-
guage, BASIC09 is particularly easy to
work with. It is similar to conventional
BASIC languages that many people
already know. BASIC09 differs substan-
tially, however, in how it deals with
variables. Initially, this can be a prob-
lem to an inexperienced programmer.
But, once one has developed an under-
standing of BASIC09 variables, the pro-
gram is less difficult. There also comes
a greater appreciation of the program's
power.

Accordingly, a substantial portion of
last month's column discussed defining

puters and specializes in basic pro-
gramming. With Don Dollberg, he is

management program.

variables used in a survey analysis
program. Another major topic of the
last month's column was setting up the
disk files. If you have not read that
article, it is a good idea to do so before
proceeding with this article.

We will now move into the data entry
part of the program. To reset the stage,
I have 350 of 3500 survey response
forms. Each form has a dozen items,
one or more of which can be checked.

The simplest way from a program-
ming standpoint is to write a series of
INPUT statements, each of which asks a
"yes" or "no" question. One problem is
that I need to read each one each time
to stay synchronized in choosing an
appropriate keystroke.

Another is that this approach does
not provide for corrections after a
question is answered. The input screen
has a menu showing each possible
choice. A pointer can be moved up or
down with the arrow keys. Choices are
selected by moving the pointer and
pressing ENTER.

REPERT

( * Input Screen * )

PRINT CHR$(12);
SHELL "tmode -1 echo"
SHELL "tmode .1 -pause"

Since the data-entry process takes
quite a bit of time, the program needs

to loop through the code for each form
until it receives a signal to quit. BASIC09
provides a number of control structures
to facilitate this. REPERT . . UNTIL serves
our purposes best. When it gets to the
end, the condition is tested and, if true,
the loop is exited. If the condition is not
true, program control is returned to the
line below the REPERT.

BASIC09 does not have a cis com-
mand like Color BASIC. ASCII Charac-
ter 12, at the top of the form, starts a
new page on a printer, but also clears
the screen and puts the cursor at the
upper left corner.

BAS1C09 makes full use of OS-9 serv-
ices and expects the programmer to do
so as well. One of these services is
writing to the screen. When you boot
OS-9, three standard, numbered, I/O
paths are opened. These are input from
Keyboard 0, normal output to Screen 1,
and error output to Screen 2. These
paths can be redirected so that errors
can be sent to the printer or to a file.

After you have booted, OS-9 handles
special characters sent along these
paths. For example, the ASCII Charac-
ter 12 clears the screen. The keyboard
up arrow normally sends this character.
When you are working at the OS-9
prompt, the ASCII 12 is trapped by
Shell if you press the up arrow, and
OS-9 displays a period instead. When
you are in a BASIC09 program, Shell is
not in use, and OS-9 will normally send

146

THE RAINBOW May 1989

or echo all keystroke characters to the
screen and program.

Sometimes there is a problem with
this. Say, I want to move the up arrow
up one line. If I don't do something
when I press the up arrow, OS-9 clears
the screen and the program prints the
cursor at a line that has been erased.
BAS1C09 can send a message to OS-9 to
turn the echo off so when I press the up
arrow, the ASCII 12 character goes
only to the program that does my
bidding. This is fine until, for instance,
I type in a ZIP code and want to see
what I am typing. If echo is off, turn it
back on by typing shell "tmade .1 -
echo". This line is in the program just
before I start to use the arrow keys to
move the cursor. Now when the pro-
gram loops back for the next form's
data, echo is off so I add shell "tmode
.1 echo" to turn it back on for the ZIP
code entry.

OS-9 also prints the screen in pages
and then stops for you to read what was
printed. When you press a key, OS-9
continues with the next page. This
feature is called pause. You can set this
to however many lines you want using

Xmode and then immediately make a
new boot using Cobbler. The settings in
your computer will be the settings when
you boot again using the new boot disk.
To manage paging with the program
instead of OS-9, shell "tmode .1 -
pause" turns pause off. Note that under
Level II, Tmode only affects the window
where it is used and not other active or
future windows.

showed assigning text to each array
member. Here we use that array to print
the menu entries. I assume that most of

BASIC09.

the delimiter, ; , between the string and

in Color basic. If you forget, BASIC09
will remind you when you try to enter

RUN printat(15,4)

countl=countl+l

INPUT "ZIP CODE: ",zip(countl)

Printat is a separate function that
moves the cursor to a specific column
and row in other columns. The INPUT
statement is conventional. You can use
, or ; for the delimiter.

RUN printat(9,G)
PRINT ">;"

With the ZIP code entered, you can
now enter the other data. The > is
printed pointing to the top choice on the
list.

(* Data Input *)

SHELL "tmode .1 -echo"

rou=G

flag=l

Now the echo is turned off so we
avoid the CHR$(12) screen-clearing
problem. You will see why we set f lag=l
after the next code block.

WHILE flag=l OR answerOCHRS ( 13 ) DO
GET 80 , answer
RUN isupper ( answer )

This loop cycles back until all choices
have been made. Since WHILE. .DO tests
for specified condition at its beginning,
I set f lag=l to assure entry, though on
checking back I see the answer must be
either I or L to have gotten this far.
These things happen in quickly written
programs where sometimes things are
done locally to ensure power that may
not be needed.

The command BET tto works better
than IN KEY. It waits for a keystroke
rather than making the programmer
write a loop to keep checking for input.
In this case, the answer was DlMensioned
as STRING[1], so any keystroke, includ-
ing ENTER, satisfies BET and allows the
program to move on. If the answer had
been DlMensioned for more than one
character, you would have needed to
either enter the number of characters or
press ENTER to terminate the entry.

The keystroke Q can be entered to
terminate data entry. This can come in
lowercase SO isupper ( answer ) is run to
promote the character to caps if needed.

(* MOVE CURSOR UP *)
IF answer=CHR$(12) THEN
IF row>G THEN

RUN printat(9,row)

PRINT "

row=row-l

RUN printat(9,row)

PRINT ">;"

fJLagri
ENDIF

When you key an up arrow, the first
IF. . THEN statement is satisfied and the
cursor-up routine is entered. If the
cursor is positioned below Row 6, there
is room to move up and the second
IF.. THEN statement is satisfied. The
program then erases the cursor on the
screen by printing a space on top of it
and printing a new one on the row
above. The flag is set to 1 to show that
the last operation was a cursor move
rather that a selection of a list item.
Note that if the cursor is pointing to the
top list entry, nothing happens.

(* JUMP EMPTY ROW *)
IF row=14 THEN

RUN printat(9,row)

PRINT " ";

row = row-l

RUN printat(9,row)

PRINT ">;"
ENDIF
ENDIF

We have to deal with a blank line in
the list separating two types of data. If
the cursor is moved to Line 14, the
blank, this ctide simply moves it up to
Line 13. The flag has already been set
to get to Line 14 so it does not need to
be reset. The final ENDIF statement
terminates the cursor-up code.

(* MOVE CURSOR DOWN *)
IF answer=CHR$(10) THEN
IF row<lB THEN

RUN printat (9, row)

PRINT "

row=row+l

RUN printat(9,row)

PRINT ">;"

flag=l
ENDIF

(* JUMP EMPTY ROW DOWN *)
IF row=14 THEN

RUN printat(9,row)

PRINT " ";

row=row+l

RUN printat(9,row)

PRINT ">;"
ENDIF
ENDIF

The cursor-down code almost mir-
rors the cursor-up code.

(* RESET FLAG FOR ADDED SELECTION

IF flag=0 AND ansuerOCHRS ( 13 )
THEN

flag=l
ENDIF

A situation can occur where the
cursor is at the top or bottom of the list,
and the user presses the arrow that
moves the cursor beyond the list. In this
case nothing happens, and the flag is not
set to I. The code above assumes the
user wants to make another choice and
sets the flag so that pressing ENTER will
not terminate data input.

(* ADD SELECTION TD RECORD *)

IF flag=l AND answer=CHR$( 13) THEN

ON rou-5 GOSUB 6,7,8,9,10,11,12,

13, 14, 15, 16, 17, IB

f lag=0

ansuier=""

rec(countl) .ar=l
ENDIF

To select or deselect a choice, move
the cursor to the choice and press
ENTER. Moving the cursor sets the flag
to 1 and ENTER lets the program enter
the code piece.

ON x GOSUB uses the value in X to count
to a line number right of the GOSUB and
then sends the program to that line.
Counting starts with 1, while the first
entry on the list is in Row 6. Subtracting
5 from the row gives us the needed item
number in the list.

The line-numbered subroutines fol-
low the END statement. Now the pro-
gram can never get to them except by
being specifically sent by a GOSUB or
GOTO. Lines 13 and 14 are given as an
example:

13 RUN printat(ll,row)

IF rec(countl) .oth=0 THEN
rec ( count 1 ) . othFl

ELSE

rec(countl) .oth=0
PRINT " ";

ing to this choice, rec(countl) .oth, is
checked to see if it is zero (not selected).
In that case, rec(cauntl) .oth is set to
1, indicating selection, and an O is
printed to mark selection on the screen.
If the item had been previously selected,

the code after ELSE would be used to
deselect the item and remove the selec-
tion mark from the screen. The print-
at ( 9 , row ) moves the cursor back where
it was before the subroutine was en-
tered.

you accidentally select it, simply press

it jumps right in to start the next form.

This is simply a special IF.. then

Simple CoCo interfacing for the all- thumbs Co Co Nut

Dev ces, Unlimite

By William Barden, Jr.

Rainbow Contributing Editor

Stop! Don't turn that page! Even if you've never held
a soldering iron, even if you don't know what a
transistor looks like, I'm going to show you how to
do some amazing things with your CoCo 1, 2 or 3. For under
$20 and for about one hour's work, you'll be able to do these
things (and more):

• Detect night and day

• Detect when room lights are turned on or off

• Measure wind direction

• Make a sensitive light meter

• Measure inside and outside temperature

• Count the customers coming through your shop's door

• Make a multi-circuit burglar alarm

• Make a water-level detector

• Sound an alarm when your mail is delivered

Does this sound like hype? It isn't. Does it sound as if you'll
need a master's degree in electrical engineering? You won't.
I'll show you how to do these things and more with little cost,
no modifications to your CoCo, easy-to-obtain parts, no
dangerous voltages and no experience whatsoever. Inter-
ested? Read on . . .

The Simplest CoCo Interface

To do these things on the CoCo, you will use the joystick
inputs as a simple interface and use simple, low-cost switches
and devices available at your local Radio Shack or other
electronic parts store. There are two joystick inputs on every
CoCo, whether you have a CoCo 1, 2 or 3. Normally they
are meant to be used with joysticks for games or screen

Bill Barden has written 27 books and over 100 magazine
articles on various computer topics. His 20 years* experience
in the industry covers a wide background: programming,
systems analysis and managing projects for computers
ranging from mainframes to micros.

drawing programs. However, the inputs can be used for other
purposes.

You don't really need to know how the joysticks work to
hook up some of the devices I'm going to show you, but let
me give you a thumbnail sketch anyway. The joystick
internals are shown in Figure 1 .

It's a simple electrical device, consisting of two potentiome-
ters and two switches.

The potentiometers are variable resistors that change a
resistance value from about 0 to 100,000 ohms. Resistance
is an electrical quantity similar to friction in a water pipe —
increase the resistance and less current flows, just as less water
flows in a hose when you squeeze it. When you manipulate
the joystick control of your CoCo, the resistance of the two
potentiometers are changed according to the joystick's
position.

One potentiometer is affected by the up/down motion of
the joystick while the other is affected by the left/ right
motion. The resistance values of both joysticks are read by
the special circuitry within the CoCo. The resistance values
are then read by the JOYSTK command in BASIC, which returns
values of 0 to 63, representing resistance values of 0 to about
100,000 ohms. Here's a simple BASIC routine to read the right
joystick:

100 fl=JOYSTI<(0)
110 B=J0YSTI<(1)
140 PRINT ft;B
150 GOTO 100

To see the results, enter NEW

Enter lines 100 through 150. Then enter RUN. You'll see two
columns of values — A followed by B. The A value changes
from 0 to 63 as the joystick is moved from left to right while
B changes from 0 to 63 as the joystick is moved from top
to bottom.

Of course, you have two joystick plugs on all CoCos. The

Figure 1: Joystick Diagram

JOYSTK command in BASIC also reads the left joystick in this
manner:

100 R=JOYSTI<(0)
110 B=JDYSTK(1)
120 C- JOYSTK ( 2 )
130 D=J0YSTI<(3)
140 PRINT fl;B
150 GOTO 100

To see how this code works, enter lines 120 and 130 and
enter RUN. You'll see four columns representing the two
joysticks' X and Y values.

In addition to the movable lever on the joystick, there's
also a button or two to zap alien invaders or to mark screen
positions. This button is a simple, normally open switch. (See
Figure 1.) Normally open means no connection is made while
the switch is not pushed. When the switch is pushed, a
connection is made, and the CoCo can detect the change.

CoCo 3's BASIC has a special command not found in the
other CoCos that detects joystick-button pushes. Appro-
priately, it's called BUTTON and works like this:

200 E=BUTTON(0)
210 F=BUTT0N(1)
220 G=BUTTDN(2)
230 H=BUTT0N(3)
240 PRINT E;F;G;H
250 GOTO 200

To see how this works, enter OK and NEW and then lines 200
through 250. Finally, enter RUN and you'll see 0 0 0 0 on the
screen until you press buttons on the right or left joystick.
Then you'll see the number 1 in the position corresponding
to the joystick switch. The 1 will remain there until the button
is released.

If you have a CoCo 1 or 2, use the following code to read
the buttons on the right and left joysticks:

200 E=(PEEIC(&HFF00) AND 1)

210 G=(PEEK(&HFF00) AND 2)

220 IF E=0 THEN PRINT 1; ELSE PRINT 0;

230 IF G=0 THEN PRINT 1 ELSE PRINT 0

240 GDTD 200

The code above goes further into the hardware to read the
input bits for each joystick button since there isn't a BUTTON

command in this BASIC. Here's the vital thing about the
joystick ports on the CoCo: The CoCo doesn't really know
whether it's reading an official joystick value or button push
or if it's reading another resistance or switch. You can, for
example, substitute a 0- to 100,000-ohm resistance value for
one or both ports and any type of switch — even one located
hundreds of feet away from the CoCo. The CoCo software
will still return a value of 0 to 63 for the resistance and a 0
or 1 for the switch position — open or closed. Are there
devices we can substitute for the official joysticks? You bet,
and many will do wonderful things.

Substitute Switches

Let's talk about switches first. There's no reason you
cannot hook two wires to the pins of the joystick plug and
run them up to 50 feet away. When you touch them together,
the CoCo will detect the switch closure. Bare wire will work,
but there are all kinds of inexpensive switches available.

Figure 2 shows the simplest type of switch, called SPST
(Single Pole, Single Throw). Once thrown, it remains in that
position until thrown back the other way. A variation on this
type is a momentary switch, which closes as long as your
finger is on the button but opens when the switch is released.
Momentary switches come in normally open and normally
closed. For our purposes, normally open is probably best.

Another type of switch, the SPDT (Single Pole, Double
Throw) is shown in Figure 2. This switch has two positions
— A and B. It can be used the same way as the SPST by
not connecting the other position. A DPDT switch uses
another circuit enabled by the same mechanical switch. It's
overkill for our purposes, but it can be used.

Figure 4l Switches in Series and Para I lei

Many varieties of switches are momentary switches that
operate when you step on a mat, push a button, use a lever,
bring a magnet close (for security systems), etc. Almost any
switch will work with this application since the voltages and
currents are low and not dangerous. You can even make your
own switch by using two pieces of tinfoil separated by a piece
of cardboard with a cutout in the center. (See Figure 3.)
Although you wouldn't want to use it to switch 700,000 volts,
it is fine for CoCo joystick use.

Figure 4 offers another hint on switches. Switches can be
put in series if they are normally closed. In this case,
activating one or more switches will open the circuit. If you
are using normally open switches, they can be put in parallel,
so activating one or more switches will close the circuit. That
way many switches can be joined together (e.g., for a burglar
alarm circuit that uses a switch at each window).

Many electronic devices act as switches. Radio Shack car-
ries such devices as opto-isolators and analog switches that
can be connected to joystick inputs. These are out of the realm
of this article, however, so we won't go into the details here.

Substitute Resistors

Besides the millions of switches lining those parts partitions
at your local Radio Shack, there are many devices that can
be used in place of the joystick potentiometers. These are a
few we'll be using in this article:

• Thermistor: A resistor whose resistance varies according to
temperature — a kind of thermal resistor. Using a thermistor,
we can measure temperature reading.

• Cadmium Sulfide Photocell: A resistor whose resistance
varies with the amount of light it receives. Used to measure
the intensity of sunlight or room lights, or to detect when
lights are turned off or on in a room. (See Figure 5.)

• Standard Potentiometer: A typical pot, or potentiometer,
can be used in place of the one found in the CoCo joystick.
Like switches, there are a million varieties of pots that range
in ohms and may be either linear or audio taper. For our
purposes, use a 100,000-ohm pot (100K) with a linear taper.
The linear taper ensures that a rotation of one half turn will
change the resistance by one half. (See Figure 5.)

How to Measure the World with Your CoCo

The first step in using your CoCo for the applications
mentioned above is to replace one or more joysticks with a
special cable. You can leave one joystick connected and plug
the cable into the other joystick plug. Or you can unplug a
joystick and replace it with a special cable.

One way to get a special cable is to sacrifice a joystick or

high-resolution joystick interface ($19.95 or $9.95). Cut the
cable, getting as much length as possible. Strip the outer
covering with scissors or wire cutters and expose two inches
of each wire. Then cut off about one-half inch of covering
on each wire to expose the bare wire.

You can also buy an Archer 6-Pin DIN Plug (Cat. No. 274-
020). This plug fits the CoCo joystick connector. The bare
DIN plugs require soldering five or six wires — no great chore
if you're handy with tools. Use rosin-core solder and a small
soldering iron. Use any general, stranded hookup wire. (Solid
wire breaks easily after repeated bending.) Any gauge from
18 to 24 will do nicely.

The ideal cable has a 5- or 6-pin DIN plug on one end to
fit the right joystick connector and five or six wires on the
other end. Connect alligator clips (Cat. No. 270-1545) to the
five or six ends. The result will look like Figure 6.

Find and mark the function of each wire. To do this, trace
the wires from the connector end either visually or by a
continuity tester. (The pin-out and a simple continuity tester
are shown in Figure 7.) Put a piece of masking tape around
each lead as it is identified. (By the way, as I write this, I am
connecting each lead to all other leads. There's no blinding
flash of light as the CoCo keyboard melts down into a slag
of plastic and Tandy labels.) Don't be too concerned about
getting the leads all correctly identified.

Are the leads identified and marked? Good, now we can
get down to business.

Dark and Light Detector

A cadmium sulfide photocell (Cat. No.276-116A) can be
used to detect light or dark conditions. Connect the photocell
to a 15K-ohm, [4-watt resistor (Cat. No. 271-1337) and to

routine:

100 A=JOYSTl<(0)
140 IF R > .35 THEN PRINT "LIGHT" ELSE PRINT "DfiRK"
150 GOTO 100

Now the photocell can be used to measure dark or light.
The limit, value can be changed depending upon your
interpretation of dark or light. In our test oh a CoCo 3, the
value shown was between a darkened room and a room in
overcast daylight. Some potential uses for this application
include sounding an alarm (with the BASIC SOUND command),
signaling light leakage in a photo darkroom, or triggering a
wake-up program that plays music when the sun comes up k

The photocell can be located hundreds of feet away from
the CoCo — the resistance of the wire will be small in
comparison to the photocell. The value of A will determine
just what you want to do with the photocell.

A Sensitive Light Meter

The CdS photocell is capable of more than determining
dark- and light-limit values. It can be used to discern
differences in up to 64 shades of lighting. Use an inexpensive
potentiometer as shown in Figure 9 to get a wide range of
lighting values. Adjust the potentiometer for the best
sensitivity under the lighting conditions you want to measure.
In our test, a lOOK-ohm potentiometer, adjusted to about
mid-scale, measured lighting conditions inside a house.

You can scale the value measured by multiplying by a
constant. This may change the measured value into more
useful units. You can also establish as many limit values as
you want based on these results:

1000 IF A<30 THEN PRINT "CLOUDY" ELSE IF R<40 THEN PRINT
"PARTLY CLOUDY" ELSE PRINT "SUNNY"

Some potential uses for this application include a photo-
graphic contrast meter, ambient light measurement, weather
conditions or a light pen. Use up to four inputs (two channels
on each joystick connector) to measure light intensity at four
locations.

A Thermometer

A thermistor (Cat. No. 271-110) can be used to measure
temperature; however, since the maximum number of values
is 64 (0 to 63), it may be difficult to get within a degree of
the temperature. Use the thermistor for an approximation of
temperature. Like the photocell, this application can do a
limit check to test for high versus low temperatures or
measure a range of temperatures. The software is identical
to the code for the photocell.

I calibrated the thermistor by immersing it in ice water and
allowing it to reach room temperature (about 68 degrees in
chilly California) and then measuring the body temperature '
of a Shetland sheepdog (by a procedure I won't document).
The reading with the setup in Figure 10 was 17 for ice water,
25 for room temperature, and 32 for the Sheltie. Unfortu-
nately, intermediate readings are not linear (i.e., halfway
between 32 degrees and 68 degrees — 49 degrees — will not
necessarily give a value of 21). You might have to get a value
and convert it in the following manner:

1000 IF A=XX THEN A=XX ELSE IF A=XX THEN R=XX ELSE IF R=XX
THEN FFXX ELSE . . .

Like the photocell, the thermistor may be located hundreds
of feet aWay and connected by a pair of wires. Use up to four
inputs (two channels on each joystick connector) to measure
temperatures at four locations. Potential uses for this
application include fire detection, attic overheating, or
freezing-point detection.

Measuring Wind Direction

A wind-direction measuring device may be made from a
Radio Shack 100K linear taper potentiometer (Cat. No. 271-
092). The pot can be opened by bending back the side tabs.
Inside you'll find a stop that limits the rotation of the shaft.
Break off this tab (see Figure 11) and put the pot together
again. You now have a pot that will rotate clockwise or
counterclockwise without limit. It takes some force to rotate
the shaft; however, a large wind vane (shown in Figure 12)
will do the job — even for slight winds.

The value returned will have to be converted to direction.
The setup I used is shown in Figure 13. This can be; done
with the following routine:

1000 IF R=0 THEN D$="N"
1010 IF R>0 RND R<=5 THEN D$="NE"

There is a discontinuity in the pot's operation. When the
pot is in the region where the stop was removed, it will read
zero. Compensate for this by orienting the pot in a north-
western direction. Zero will then be read from northwest to
northeast.

A Burglar Alarm

A burglar alarm can use one to four button inputs on one
or both joystick connectors. Wire normally open switches in
parallel and normally closed switches in series. The alarm
may detect either one or zero (normally closed or normally
open). Radio Shack and other stores have a host of security
devices, many of which are switches — magnetic door
switches, window switches, mat switches, etc. For more
information on security, buy How to Hook Up High-Tech
Electronics (Cat. No. 62-1088) at Radio Shack. A sample

Naturally, the switches can be located dozens of feet from
the CoCo. This is not generally recommended procedure for
this electronic connection, but I experienced no difficulties
and no false readings on inputs from 60 feet away using
intercom cable. Any size wire from about 18- to 24-gauge may
be used. Stranded wire is best because it is less susceptible
to breakage after bending, but solid wire can be used in a
permanent installation.

Roller-Switch Applications

Radio Shack sells a switch (Cat. No. 275-017) with a roller
arm, which triggers with very light pressure. It can be used
in an application such as detecting mail delivery. (See Figure
15.) Opening the mail box opens the switch, which can then
be detected remotely by your CoCo. The roller switch can
also be used in a burglar alarm application — when an object
is lifted, the switch will spring open. To do this, use the code
from above.

A water-level detector can be made by a toilet-bowl float
and arm, as shown in Figure 16. Rising or falling water of
a certain limit will trigger the switch.

R.S.B. loads and saves files using OS9's file format, so we've also

included utilities to transfer BASIC programs and data files betwen OS9 and BASIC disks. Of course, you can't use R.S.B. to run machine language
programs, and some BASIC commands work slightly differently under R.S.B.

Your BASIC programs can take full advantage of great OS9 features like hard disks, no-halt floppies, multi-tasking, and 2 MHz operation.

R.S.B. requires a CoCo 3 with at least 128K RAM (51 2K recommended), a floppy controller
with either Tandy Disk Extended Color BASIC or DISTO CoCo 3 CDOS, and Level 2 OS9.
