LETTERS TO THE
Glad to Be of Service
Editor:
After reading RAINBOW for four years, I
have to write and let you know I enjoy it very
much. But 1 have never seen such a fine piece
of workmanship as the article by Marty
Goodman, "RTTY for the Color Computer"
on Page 36 of the November 1986 issue. I
use this program quite a lot. Thank you and
1 hope to see more of this kind of program-
ming. Keep up the good work.
Gerry Farmer
Calgary, Alberta
Where Are They?
Editor:
I was searching for one-liners in my
November 1986 rainbow, but to my sur-
prise, I could not find even one. Did you
discontinue them? Or did I just miss them?
Michael Jacobs
Brooklyn, NY
A one-liner junkie, eh! Well, never
fear, that was just a short break.
We get dozens of one-liners
monthly and plan to keep publish-
ing them indefinitely.
BACK TALK
Editor:
In the November 1986 issue. Page 8, a
reader asked about using the CoCo to
control a model railroad layout. I suggest
that he contact the Model Railroad, Kalm-
bach Publishing Co., 1027 N. Seventh
Street, Milwaukee, WI 53233. They proba-
bly have an article in one of their back issues.

COCO 3
Editor:
I'm an engineering student at Ohio State
University, and my CoCo 2 served mainly
as a word processor (1 use VIP Library). The
VIP Library seems to function on the new
machine, but I have high expectations of a
new "super-processor" to come out in the
near future. The purpose of this letter is to
simply let the software companies know that
we (the new generation of CoCo 3 users) are
interested in new programs and program-
ming techniques as soon as they are avail-
Randy Harrison
Columbus, OH
Didn't Have Him in Mind
Editor:
Finally! The CoCo 3 I had ordered in
August was in the store waiting to be picked
up. I got it Friday, returned it Monday.
I have no interest in games or graphics.
I use two CoCo 2s in my business for
bookkeeping, billing, record-keeping and to
automate my recording studio's audio/
video synchronization system. I write all my
own programs in BASIC, and that's the catch.
Unfortunately, the folks at Tandy didn't
seem to have had people like me in mind
when they developed the CoCo 3. It offers
very little that I don'l already have using a
64K CoCo 2 and Computerware's excellent
Screen Expander. All the extra memory and
faster operation are not accessible from
BASIC.
So how about a software package that has
Hi-Res screen with simple PRINT@(x,y)
syntax, printing at the beginning of a line
that doesn't wipe out the rest of the line, all
keys repeat if held down, type-ahead buffer
and more memory for program and variable
storage (without toggling, banking, or
special commands). For 5I2K versions: a
RAM disk that can be used as if it were
Drive 3, using regular Disk BASIC com-
mands, and a print spooler.
In short, could somebody market a pro-
gram that would make the CoCo 3 as
exciting for a BASIC user like me as it is for
the rest of the CoCo Community?
Rob Edward
Greenwich, CT
The Primary Guide
Editor:
Being the new owner of a CoCo 3, 1 would
like to make a few comments on my expe-
riences. First, I was pleased to find a large
number of my CoCo 1 software would run
on CoCo 3. These included Telewriter 64.
Spectaculator, Graf plot. Desk Mate. Ark
Royal games, etc. One program that would
not run was my VIP Database. Softlaw told
me they had no plans for CoCo 3.
I have also received no help from the local
Radio Shack centers, who seem to be un-
informed about CoCo 3 capabilities, soft-
ware changes, or when OS-9 Level II will be
available. Regarding any technical ques-
tions, I am usually referred to Fort Worth
Headquarters (with a toll number, of
course). It seems to me that the advice
available from Radio Shack centers has
deteriorated significantly since I bought my
first CoCo in 1981.
Once again, we CoCo users can be very
thankful for THE rainbow. You are the only
source of information we need to achieve the
full capability of our favorite computer. The
manual for CoCo 3 does not even mention
how to gain use of the full 128K. The
excellent articles that have appeared in
rainbow since the CoCo 3 debut have
served as the primary guide to the CoCo 3.

Some Tips to Pass Along
Editor:
I have been working with my new CoCo
3 and would like to pass along some obser-
vations.
The 16K version of J DOS (Version 1.23)
is not compatible with the CoCo 3 in the 64K
mode (the mode at power-up). If you have
JDOS disks, the COPY command seems to
work, as does DSKINI, so you can copy your
files individually from a JDOS disk to an
RS-DOS disk. LORD and LOflDM do not
work; neither does D05. The reason for this
seems to be that on the new CoCo, only the
first 8K of the cartridge memory is reserved
for ROM packs. The upper 8K is dedicated
to the Super Extended basic However, I

AUTOTERM moves smoothly
and quickly between word proces-

action. Create text, correct your
typing errors; then connect to the
other computer, upload your text,
download information, file it, and
sign-off; then edit the received
data, print it in an attractive
format, and/or save it on file.
Editing is super simple with the
cursor. Find strings instantly, too!
Any operating parameter, such as
screen width, can be altered at
any time. Uncompleted com-
mands can be cancelled.
PUTTY IN
YOUR HANDS
The word processor can be
used to create, print, and/or save
on file your personal KSMs. They
let AUTOTERM act like you. For
example, it can dial through your
modem, sign-on, interact, perform
file operations, & sign-off; an
entire session without your help.
KSMs can answer the phone,
prompt the caller, take messages,
save them, hang-up, and wait for
the next call. The KSM potential
is unbelievable!

tried POKE S.HFFDE, converting to the 32 K
mode, and all the JDOS commands seemed
to work.
When operating with JDOS, the new
Super Extended commands will not work,
and they will not be converted to the proper
codes if you are writing a program under
JDOS. If you write a program under JDOS,
using the new commands, you can save the
program in ASCII format under JDOS and
then load it under RS-DOS and it will work.
OS-9 Version 01.01.00 will not boot, but
Version 02.00.00 will. 1 had hoped that the
80-column driver would work with the new
CoCo, but it doesn't.
In the October 1986 issue, Marty Good-
man stated that VIP Writer would not work
on the CoCo 3, but I have not had any
problems with it yet. [Some versions work;
some don't. See Jim Reed's column in the
January 1987 issue.] I have loaded old files,
etc., and they work fine — that is, if you
don't try to load while the 40- or 80-column
screen is in effect.
One nice feature of the new system is its
error-trapping routine. This goes a long way
in smoothing out the operation of a program
since crashes can be bypassed when errors
are encountered. However, the manual
supplied with the computer gives only the
codes for the basic errors (see Page 321),
and did not give the codes for disk errors,
which, to me, is where the codes really fulfill
their purpose. By experimenting, I found
most of the codes. I will give the numbers
with the symbols, but will not attempt to
explain them.
25=UF
3I=FN
26=NE
32=FS
27=BR
33=AE
28=DF
34= FO
29=OB
35=SE
30=WP
37=ER
This sequence follows the same order as
JDOS, so 1 would suspect that Error 36
should be VF.
After setting up an error trap, it can be
turned off later in the program by inserting
the command ON ERR GDTO 0. This puts you
back in the normal mode in which the
program is aborted and the error message is

CoCo Max Compatibility
Editor:
I recently obtained CoCo Max for use
with my 64K CoCo 2 and Star NX-10
printer. The results have been fantastic.
Initially, a problem arose with CoCo Max's
compatibility with the new Star NX-10
printer. The printer was not shown or listed
as being supported and Colorware could not
offer any suggestions. I was surprised and
somewhat dismayed that CoCo Max did not
work by entering the other Gemini/ Star
printers as given. I took a long shot and tried
it with the Epson FX series (printer Line 5
in the program) and it worked! I would like
to pass this on to any others who might
initially experience CoCo Max compatibil-
ity problems with the new Star NX-10

CoCo Version Wanted
Editor:
I've found just the program I'm looking
for — it's a database program that keeps
track of a collection of videotapes and also
prints out labels for the tapes. It's called
Video Tape Tracker. The problem is that it's
available only in MS-DOS and TRS-DOS.
I called the company. Prosoft, to see if they
made a version for the CoCo, but no luck.
I'd like to see something like that for the
CoCo. Some of you software entrepreneurs
develop such an animal. I'm sure you'd find
a market, especially with the assured pop-
ularity of the CoCo 3!

Is it possible to publish the complete

We have considered publishing
an article about the CoCo 3 mem-
ory map, however, such an exten-
sive report would have to be done
over a period of several months
and would take many pages. It is
unlikely in the near future. We do
ask that you watch for separate
publications dealing with such
subjects advertised in future issues
Of THE RAINBOW.
For your information, we did
publish a complete memory map
of the Color Computer in the July,
August, September and December
1983 issues of RAINBOW. While this
series by Bob Russell will be of
little assistance, it will give you
some idea of the breadth of the
project.

Promoting CoCo —
Everyone's a Winner
We got into a lively exchange of messages on Delphi the other
night concerning the Color Computer (what else?) and how
we might help promote it. One of the things people were
saying was that they sure wished we could work with sales personnel
at Radio Shack stores to "educate" them into selling CoCos.
It is always dangerous when someone bounces an idea off my head.
The reason for this is simply that 1 tend to come up with more ideas
and then, often, things get out of hand. In this case, though, I think
the idea that we all seemed to come up with is a pretty good one,
and it's one you can participate in as well.
One of the "other" things I do is fly an airplane and, as such, I am
a member of the Aircraft Owners and Pilots Association (AOPA), a
group of people who fly light planes (as opposed to big jets) around
in the sky. One of the interesting relationships in the aviation field
is between air traffic controllers and light plane pilots. They very much
(as they should) depend on one another, but sometimes they get at
odds, too.
AOPA came up with a good program a few years back called
something like "Fly A Controller." Under the plan, private pilots have
been encouraged to offer a ride to ATC personnel in an effort to give
them a chance to "see" flying from the "other side."
According to all reports, this has been a good program for all
concerned. The AOPA members have gotten to know — and
understand the problems of — ATC personnel on a personal basis.
By the same token, controllers have had the opportunity to see what
it is like to deal with instructions and directions from the cockpit.
AOPA even has a small area of its monthly magazine devoted to
reports from both controllers and pilots. I read these regularly,
because oftentimes some of the comments are very interesting indeed.

I thought about this program as the
discussion was continuing on Delphi.
Then 1 recalled we did something very
much like this several years ago, when
the original Color Computer came out.
There were a lot of people excited about
the CoCo — and quite a number of
them spent some time in their Radio
Shack stores and computer centers
infecting store personnel with that same
excitement,
they direct business. These salesmen are
usually very CoCo-oriented.
It strikes me that we can do this all
again, and that it is very much like the
AOPA program. As with everything,
something like this has to be a win/ win
situation — but there is no reason it
should not be so. Let's look at it for a
moment.
Of course, we all want more people
in the CoCo Community for so many
*'A number of Color
Computer Clubs have
become strong by working
with people in their local
Radio Shack stores,"
Some of those relationships last until
this day. A number of Color Computer
Clubs have become strong by working
with people in their local Radio Shack
stores. Store personnel have directed
new CoCo owners to users groups when
they sold computers. A few clubs even
have "designated salesmen" to whom
reasons it would be almost silly for me
to enumerate them. At the same time,
a Radio Shack salesperson is interested
in making sales — and commissions.
Obviously, the two go together.
May 1 suggest that each of you —
individually or through your club, if
you belong to one — take 10 to 20
minutes out and stop by your local
Radio Shack store (of whatever kind).
Tell the store manager you'd like to help
him generate some business and ask
whom you could work with. Then help.
Make sure you answer any questions (or
find someone who can). Tell them about
your club (if you belong to one). And
promise to direct some business to
whomever it is that is interested.
That's a win/ win situation. And.
point out two things to whomever you
speak with.
The first is that you're willing to help
as much as you can. That is really
important. The second is that almost no
CoCo owner stops buying things for his
or her computer once the computer
itself is purchased. The additional sales
any person in a store can make through
the sale of just one CoCo can be con-
siderable. So, even if the original "box"
is not too expensive, all the things that
will be bought for that "box" over the
years can add up to significant commis-
sions for the salesperson who is inter-
ested and develops a rapport with the
typical CoCo owner.
Let me know how things work out.
As I said, you can do this through a club
or on your own. One thing is for sure,
you'll be doing something to help the
CoCo Community grow and you will be
enabling more people to learn about our
wonderful computer. I think it will
benefit all of us.
And let me know how it works out.
We'll run some of your responses in our
"Letters" column.

We've come a long way, CoCo . . .
. . . and there's a long way to go.
"W" a seems that what I need is a CoCo 3 mode for my old CoCo. Now,
I I f I could "get into" that. Yeah, I know all that stuff about it not being
.M. ^economically feasible, but it would give me a real kick to flip a toggle
switch on the side of my "CoCo 1 " and have it shift into a full-blown CoCo
3 emulation.
Hmmm, maybe I could bolt a CoCo 3 on the bottom side of my computer
desk and run a few more wires into the back end of my present CoCo.
"What is he talking about?" you ask. Well, the truth is, I have been sort
of dragging my heels about getting a CoCo 3. Yep, it appears that the
managing editor of RAINBOW may be the last kid on the block to get a
new machine.
While two new Color Computer 3s are waiting, in the box, right outside
my door, 1 still have a CoCo 2 in my office and my faithful first CoCo
at home. Even though Cray, Dan, Jutta and even Angela and Jody latched
onto 128K and 512K CoCo 3s here at the office like hungry hounds on
a meat wagon, I'm still a holdout. People are beginning to talk, too. 1 feel
like the last bottom-land farmer who refuses to move out to make way
for the TVA. "Poor Jim," they must be saying, "he just won't go with the
flow."
Well, why should I? I mean, I didn't spend four years with my battle-
scarred veteran just to chuck it aside and replace it with some shavetail
rookie fresh off the boat. I feel like that guy in the Midas TV commercials
who is still driving "01' Betsy" and still cashing in on that lifetime muffler
guarantee. The biggest difference is that my machine (no, I haven't named
it) has never been in the shop since I first took delivery of it in Lonnie
Falk's basement. Yessir, my ol' buddy. Dr. Doom, and I both got 16K
CoCos for our birthdays and Bob Rosen himself had added 32K
"piggyback" upgrades to each. Since that time, my CoCo's gone through
some changes, that's for sure: lowercase board, 64K chips, new keyboard,
you name it. And, far from slowing down with age, my CoCo's just as fast
as it ever was, has a much better memory, does more than it ever did and
learns new tricks every day. So, we're not ready to part company by any
means. We go back a long way and we have the momentum to keep forging
on, too.
Without getting maudlin about a plastic shell full of silicon, I do have
a soft place in my heart for my numero uno. And, while it is inevitable
that the playful puppy of a new machine, with its own special appeal,
eventually will find a way to my heart, too (I do like that 80-column text
mode), I'm not going to cast my old CoCo aside any more than I'd trade
in my loyal, gray-muzzled Newfoundland, Onyx, for some new, improved
model of dog.
Why am I telling you all this? Just so you'll know thai we know there's
plenty of life left in our CoCo Is and 2s and that, as attractive as that new
model is, as long as this "ol'Sarge"is M.E. of this outfit, RAINBOW'S going
to keep marching to the same drummer who got us here and nobody's going
to fall out of the ranks.
So, old soldier or new recruit, if you want to get into step with the CoCo
Community, why not ease into the rhythm with a year's subscription? It
provides a once a month cadence that's hard to beat: CoCo 1,2, 3, CoCo
1,2, 3, CoCo 1,2,3. . .

When creating a program in
BASIC, it is impossible to keep
out users, or safeguard it
from tampering and having someone
put their own name in it.
Load Mask was made as a counter
measure to just that. Until the program
is executed, the user has no way to enter
and change it, and afterward, a BREAK
key disable and other routines can keep
him out completely. The program itself
is simply a machine language loader
that fools the computer into thinking
that the BASIC program in memory is
machine language. This loader also
encrypts the BASIC program using a very
simple technique that stops the listing of
the BASIC program after it is loaded.
Glen Dahlgren has created many pro-
fessional games for the Co Co including
Hall of the King, Dragon Blade and
White Fire of Eternity. He is currently
a student at Penn State College. His
non-computer interests include fan-
tasy/science fiction role playing and
racquetball.
PUT
The BASIC Program
In this section I assume you have a
disk-based system. This is different
from the tape system because of where
the CoCo locates the BASIC program. In
the disk-based system, the computer
throws the program to the end of graph-
ics memory (SE00-S25FF on startup).
This can be changed later by the PCLEAR
command within the BASIC program,
but not before the program is run. This
is because the memory (S2500-S25FA) is
used for the ML loader and can be
written over after the BASIC program is
loaded and run, but not before. There-
fore, a program that clears memory
before the program is run using the
PCLEflR command or the various pokes
(POKE 25, G: NEW, etc.) cannot use this
loader.
Now we have established where the
basic program starts, (S25FF) but not
where it ends. The CoCo has a place in
memory where it keeps track of the start
and end of the BASIC program. This area
is drawn on from the loader to configure
it to encrypt only the part of memory
that holds the BASIC program. You must
also access this information, but I'll tell
you how to do this later.
The Amazing A-BUS\&
An A-BUS system with two Motherboards
A-BUS adapter in foreground
The A-BUS system works with the original CoCo,
theCoCo2 and the CoCo 3.
Aboutthe A-BUS system:
• All ihe A-BUS cards are very easy lo use with any language lhal can
read or write lo a Port or Memory In BASIC, use INPand OUT (or PEEK and
POKE with Apples and Tandy Color Compulers)
• They are all compatible with each other. You can mix and match up to 25
cards to III your application Card addresses are easily set with jumpers
• A-BUS cards are shipped with power supplies (except PD-123) and
detailed manuals (including schematics and programming examples).

resistor 8 bit resolution (20mV). Conversion time 120us Perfect to
measure voltage, temperature, light levels, pressure, etc. Very easy to use,
1 2 Bit A/D Converter AN-146:$139
This analog to digital converter is accurate to .025%. Input range is — 4V to
+4V. Resolution: I millivolt. The on board amplifier boosts signals up to 50
limes to read microvolts. Conversion lime is 1 30ms. Ideal lor thermocouple
strain gauge, etc, I channel (Expand to 8 channels using the RE-156 card)
Digital Input Card in-141:S59
The eight inputs are optically Isolated, so it's sale and easy to connect any
"on/oil" devices, such as switches, thermostats, alarm loops, etc. lo your
computer. To read the eight inputs, simply use BASIC INP (or PEEK).
24 Line TTL I/O dg-i48:$65
Connect 24 input or output signals (switches or any TTL device) to your
computer The card can be set for: Input, latched output, strobed output,
strobed Input, and/or bidirectional strobed I/O Uses Ihe 8255A chip

Plug into the future
With the A-BUS you can plug your PC (IBM, Apple,
TRS-80) into a future of exciting new applications in the fields
of control, monitoring, automation, sensing, robotics, etc.
Alpha's modular A-BUS offers a proven method to build your
"custom" system today. Tomorrow, when you are ready to take
another step, you will be able to add more functions. This is ideal for
first time experimenting and teaching.
A-BUS control can be entirely done in simple BASIC or Pascal,
and no knowledge of electronics is required!
An A-BUS system consists of the A-BUS adapter plugged into
your computer and a cable to connect the Adapter to 1 or 2 A-BUS
cards. The same cable will also fit an A-BUS Motherboard for
expansion up to 25 cards in any combination.
The A-BUS is backed by Alpha's continuing support (our 11th
year, 50000 customers in over 60 countries).
The complete set of A-BUS User's Manuals is available for S10.

What is CoCo Max ?
Simply the most incredible graphic
and text creation "system" you have
ever seen. A Hi-Res Input Pack (more
on the pack later) is combined with
high speed machine language
software. The result will dazzle you.
CoCo Max disk system, with Y-cable.
Is CoCo Max for you ?
Anyone who has ever held a pencil or
a crayon for fun, school or business
will love it. A 4 year-old will have fun
doodling, a 1 5 year-old will do class
projects and adults will play with it for
hours before starting useful
applications (illustrations, cards,
artwork, business graphics, flyers,
charts, memos, etc.) This is one of the
rare packages that will be enjoyed by
the whole family.
What made CoCo Max an
instant success?
First there's nothing to learn, no
syntax to worry about. Even a child
who can't read will enjoy CoCo Max.
Its power can be unleashed by simply
pointing and clicking with your
mouse or joystick. With icons and
pull down menus, you control CoCo
Max intuitively; it works the same way
you think.
Don't be misled by this apparent
simplicity. CoCo Max has more power
than you thought possible. Its blinding
speed will astound you.
It lets you work on an area 3.5 times
the size of the window on the screen.
It's so friendly that you will easily
recover from mistakes: The undo
feature lets you revert to your image
prior to the mistake. As usual, it only
takes a single click.
Later, we will tell you about the
"typesetting" capabilities of CoCo
Max II, but first let's glance at a few of
its graphic creation tools:
With the pencil you can draw free
hand lines, then use the eraser to
make corrections or changes. For
straight lines, the convenient rubber-
banding lets you preview your lines
before they are fixed on your picture.
It's fun and accurate. Lines can be of
any width and made of any color or
texture.
The paint brush, with its 32
selectable brush shapes, will adapt to
any job, and make complicated
graphics or calligraphy simple.
For special effects, the spray can is
really fun: 86 standard colors and
textures, all available at a click. It's
like the real thing except the paint
doesn't drip.
CoCo Max will instantly create many
shapes: circles, squares, rectangles
(with or without rounded corners),
ellipses, etc. Shapes can be filled with
any pattern. You can also add
hundreds of custom patterns to the
86 which are included.
The Glyphics are 58 small drawings
(symbols, faces, etc.) that can be used
as rubber stamps. They're really great
for enhancing your work without effort.

Control Over Your Work
CoCo Max's advanced "tools" let you
take any part of the screen, (text or
picture) and perform many feats:
• You can move it around • Copy
it • Shrink or enlarge it in both
directions • Save it on the electronic
Clipbook • Flip it vertically or
horizontally • Rotate it • Invert
it • Clear it, etc. etc.
All this is done instantly, and you can
always undo it if you don't like the
results.
For detail work, the fat bits (zoom)
feature is great, giving you easy
control over each pixel.
To top it all, CoCo Max II works in
color. Imagine the pictures in this ad
in color. If you own a Radio Shack
CGP-220 or CGP-1 1 5, you can even
print your work in full color I
There is so much more to say, such as
the capability to use CoCo Max
images with your BASIC programs,
the possibility to use CoCo Max's
magic on any standard binary image
file. There are also many advanced
features such as the incredible lasso.
Inside the Hi-Res Input Peck
Why a Hi-Res Input Pack ?
Did you know that the CoCo joystick
input port can only access 4096
positions (64x64)? That's less than
10% of the Hi-Res screen, which has
491 52 points! (256x1 92). You lose
90% of the potential. The Hi-Res Input
Pack distinguishes each of the 491 52
distinct joystick or mouse positions.
That's the key to CoCo Max's power.
The pack plugs into the rom slot (like
a rom cartridge). Inside the pack is a
high speed multichannel analog to
digital converter. Your existing
joystick or mouse simply plugs into
the back of the Hi-Res Pack.
Electronic Typesetting...
You'll be impressed with CoCo Max's
capability. Text can be added and
moved around anywhere on the
picture. (You can also rotate, invert
and flip it...) At a click, you can choose
from 1 4 built in fonts each with 1 6
variations. That's over 200 typestyles !
Examples of printouts
Printing Your Creations
There are a dozen ways to print your
work. All are available with a click of
your joystick (or mouse) without
exiting CoCo Max. Your CoCo Max
disk includes drivers for over 30
printers !
All the CoCo Max pictures are unretouched screen shots or printouts (Epson RX-80).
The whole family will enjoy
CoCo Max. Here are a few
examples of the possibilities.
All these pictures are unretouched screen photos
or printouts (on an Epson RX-80).

The Machine Language Loader
The loader is divided into two parts.
The first part encrypts the BASIC pro-
gram and is located at $2500. This is
done simply by finding the end address
and exchanging every other byte up to
it. This is very easily done and requires
no code to encrypt, but it serves its
purpose and disables the LIST com-
mand upon loading the program. This
section also puts the end address of the
basic program into the second part, a
permanent part of the final product.
The section is not used until the
execution of the BASIC program and is
saved along with it. Its processes include
de-crypting the program and setting the
BASIC pointers in memory, or telling the
computer exactly where the program is.
It is because of these pointers that you
can't just save the BASIC memory as an
M L program.
Creating the Loader
The loader can be made in two ways.
If you have Disk EDTASM or some
other compatible assembler, then you
can enter and assemble the assembly
language listing; otherwise, simply use
the BASIC program that pokes the
loader directly into memory. You can
save it by typing SfiVEM"LOflDER",
8.H2500, &H25FA, &H2500 and press-
ing ENTER.
Using the Program
First you must load a BASIC program
into memory. Make sure you have a
backup of the program saved in case
something goes wrong. Then you must
find its end address. This can be done
by typing PRINT PEEK ( 27 ) *25G+
PEEK(28). It is these two locations (27
and 2B) that hold the end address of the
BASIC program in Hex. Using the equa-
tion given, they are modified to a
decimal number equaling the end of the
program. Write this number down.
Next, load in the completed ML
loader already saved on disk. Then type
EXEC &H2500 and press ENTER. The
first part of the loader encrypts the
BASIC program and returns. Then you
must save the program as a machine
language file. The format for this is
SRVEWfilename" , start address, end
address, execute address. You must
type this in as follows: SRVEM"/i7e-
name" , &H25DB, the number obtained
from our equation, &H25DB. This saves
the file as an ML program starting at
&H25DB and ending at the end of your
BASIC file with its execution at
&H25DB. This is the execution location
of the ML loader included in the saved
file.
You're finished! You now should have
a newly-created machine language pro-
gram that can be loaded and executed
independent of any other file. Note that
this loader does not interfere with the
BASIC interpreter or BASIC functions
and can be overwritten after its execu-
tion. It simply allows the loading and
execution of the BASIC program after
which the memory it takes up is free.
Modifications and Additions
Other routines that might be of use
to a BASIC programmer would be a reset
and BREAK key disable. These should be
put directly in the beginning of the
BASIC program so as to disable these
functions as soon as possible.
To disable the reset button, you
should enter POKE 113,0. It will give
you a cold start upon pressing it.
To disable the BREAK key on all but
INPUT and LINEINPUT commands, you
can use a routine taken, with permis-
sion, from the book 500 Pokes, Peeks
W Execs. Enter the following into your
BASIC program:
FOR 1=330 TO 33G:READ H:P0KEI,
R:NEXTI:DhTh 50,98,28,175,
12G, 173,165: POKE 410,126 -.POKE
411,1:P0KE412,74
If you are familiar with machine
language and want to modify the loader
to disable any of these things, simply
remember the new start and execute
number for the completed ML/ BASIC
file, and make sure the line in the first
section that puts the end location in the
second section is also modified. One can
do this without changing the first sec-
lion or the encryption part of the loader
because they are separated in memory
by approximately 200 bytes (via the ORG
statements). Therefore, one could mod-
ify the second section without changing
the first.

HOTEt eoeo
By Dale Lear
| elcome, detectives, to the Hotel CoCo, a parlor
game filled with intrigue and suspense. The
Hotel CoCo has everything you would want in
a fine hotel — swimming pool, four-star dining room and
much more. Unfortunately, the hotel is having a slight
problem. One of its distinguished guests from THE
RAINBOW magazine staff is really an imposter. Who is he
really? Perhaps a refugee from one of the many home
computer companies that didn't have the staying power
of the CoCo. Perhaps some LOGO enthusiast bitter over
the fact that the new computer language that this game
is written in, D.L LOGO, is only available for the color
computer. Who knows? Whatever the motive, this
sinister culprit is determined to "off the hotel guests one
by one. Your mission as the hotel detective (or detectives,
as the case may be; this game can be played by any
number of players) is to determine just who the imposter
is.
The game takes place in a hotel which contains the
following rooms: Lobby, Kitchen, Dining Room, Bar,
Swimming Pool, Stairs, and six hotel rooms (rooms 101
through 106).
Besides the detectives (the players), there are six guests
at the hotel, one registered in each of the six hotel rooms.
The guests are Ms. Kapfhammer, Ms. Arnott, Ms.
Hutchinson, Mr. Falk, Mr. Reed and Mr. Augsburg. The
guests move freely about the hotel with the exception that
no guest has the key to any hotel room but his own. Each
of the guests comes to the hotel with a valuable posession.
Whenever the guests go back to their hotel rooms they
may decide to leave the valuable in the room or they may
decide to take it with them.
Dale Lear owns Dale Lear Software and makes his
living developing programs for the Color Computer.
He has authored games and other software such as
Double Back, Baseball, TSED1T, TSWORD and D.L.
LOGO. Dale, his wife, Laurel, and their six children
live in Petaluma, California.
February 1987 THE RAINBOW 27
One of the guests is really a killer in
disguise. Whenever the killer ends up
alone in a room with only one other
guest and no detectives snooping about,
he strikes! The victim is left at the scene
of the crime and, if the victim was
carrying his valuable at the time, the
killer steals it and immediately stashes
it away in his hotel room.
Each player is a detective. Each
detective takes his turn using the arrow
keys to move about the playing board
according to the spin of the wheel. All
the detectives have passkeys and can go
freely into all rooms of the hotel includ-
ing the guests' rooms. When in a room,
■•G" TO GUESS. SPACE TD PUSS
the names of the guests currently in the
room are displayed. Also, a list of the
valuables in the room is displayed.
Whenever a room is entered, the detec-
tive has a chance to make a guess as to
who the killer is, or pass.
The game begins with the prompt
"number of players:." Next, each play-
er's name is entered one by one.
The screen then displays the hotel
registration. It is advisable to make a
copy of this list, as it can be valuable
information in trying to locate the killer.
At the press of a key the game begins.
A spinner appears giving the first
player a number between one and nine.
This number is the number of squares
that the player can move on this turn.
The playing board is then displayed and
the player makes his moves using the
four arrow keys. The number of squares
left to be moved is displayed in the
lower-right corner of the screen. The
player's name is displayed in the lower-
left corner.
If the player enters a room, a picture
of the room appears and a list of the
people and things in the room is pre-
sented. Listen carefully at this lime
because if a murder takes place any-
where in the hotel you will here a chord
played. At this point the player either
enters G to make a guess as to who the
killer is, or presses the space bar to pass.
If a correct guess is made, the player
wins. If a wrong guess is made, the
player is eliminated from the game. If
the player passes, his turn is ended.
Each player takes his turn in a similar
fashion until either the killer is identi-
fied or all players are eliminated by
wrong guesses.
To run HOTEL, first boot the OS-9
operating system and execute D.L.
LOGO. Then enter and save Listing 1,
SETUP. Now, enter and save HOTEL.
Remember to delete the comments in
order to conserve memory. At this
point, you can reload SETUP and exe-
cute it. This will create several files
required for play. After you have run
this, you should not need to run it again.
All you have to do now is load and
execute HOTEL.
Good luck, super sleuths! □
Editor's note: See Dan Downard's
review of D.L. LOGO on Page 147 in the
January 1987 issue.

GRAPHICS
Love is in the air . . . and on the screen
CoCo Can Play
Cupid, Too
By Ernie DiZazzo
Move over Hallmark! Here's a program for telling
that "certain someone" exactly how you feel, with
colorful graphics and a sentimental love song.
Lovecard starts with a title screen and the instruction to
press any key to begin. Following the introductory message
and graphics, pressing ENTER starts the music (sort of like
high-tech strolling violinists) while the lyrics are displayed
on the screen. After the song has concluded, a hearts-and-
roses finale bursts on the screen, vividly declaring, "I love
you" to the object of your affections. At the bottom of the
screen, the name "Rainbow" appears as the recipient of this
message, but you can edit it to display a different name.
Lovecard is perfect for bestowing upon a loved one on
special occasions, such as anniversaries or Valentine's Day
— or just any oV time you want someone you care about
to know how you feel.
(Questions about this program may be addressed to the
author at 10800 A Esplanade Avenue, Montreal, Quebec,
Canada H3L 2Y6. Please enclose an SASE for a re-
sponse.) □
Ernie DiZazzo lives in Montreal and is a veteran of World
War II. Formerly a statistician with an electronics company,
Ernie enjoys listening to music and sharpening his program-
ming skills by reading THE RAINBOW.

Two Years In the Making. Speech Systems
was formed to develop new and innova-
tive speech products. After 2 years of in-
tensive Research and Development, we
have created a truely sophisticated
speech recognition device. Recognition
rates from 95% to 98% are typical. Until
now, such a product was outside the
price range of the personnel computer
market, and even small businesses.
EARS is trained by your voice and capable
of recognizing any word or phrase.
Training EARS to your particular voice
print takes seconds. Up to 64 voice prints
may be loaded into memory. You may
then save on tape or disk as many as you
like so that your total vocabulary is virtu-
ally infinite.
Speech and Sound Recognition. EARS is re-
ally a sound recognition system, so it re-
ally doesn't matter whether you speak in
English, Spanish, or French. In fact you do
not have to speak at all, you can train
EARS lo understand sounds such as a
musical note or a door slamming.
Hands Off Programming. Imagine writing
your own BASIC programs without ever
touching the keyboard. Everything that
you would normally do through a
keyboard can now be done by just
speaking.
Programming EARS Is Easy. LISTEN,
MATCH and other commands have been
added to BASIC so that programming
EARS is a piece of cake! The single BASIC
line: 10 LISTEN: MATCH will instruct
EARS to listen to you and return the
matching phrase.
It Talks. EARS is also capable of high qual-
ity speech. We mean REALLY high quality.
The speech is a fixed vocabulary spoken
by a professional announcer. Speech
Systems is currently creating a library of
thousands of high quality words and
phrases. For a demonstration call (312)
879-6844, you won't believe your ears or
our EARS.
DISK OWNERS. EARS will work with any
disk system with either a MULTI-PAK or
Y-CABLE. Our new Triple Y-CABLE was
specifically developed for those wishing
to add SUPER VOICE as a third device.
You Gel Everything You Need. You get ev-
erything you need including a specially
designed professional headset style noise
cancelling microphone. The manual is
easy to use and understand. Several
demonstration examples are included so
you don't have to write your own pro-
grams unless you want to. EARS will work
in any 32K or 64K Color Computer.
SUPER VOICE $20 OFF
Imagine talking to your computer and it
talking back to you. When you need an
unlimited vocabulary, you can't beat
SUPER VOICE. For a limited time, we will
give you the SUPER VOICE for $59.95 with
your EARS purchase. Even if you already
have another speech unit, here is your
chance to buy the best and save $20.
VOICE CONTROL
Applications for EARS are astounding.
Here is our first of many listening pro-
grams to come. VOICE CONTROL is a
program specifically designed to allow
you to control any appliance in your
house with your voice and our HOME
COMMANDER (sold separately) or the
Radio Shack Plug 'N' Power controller.
For example, you can control your TV by
saying "TV ON" or "TV OFF". . $24.95

Presidents Take Precedence
By Steve Blyn
Rainbow Contributing Editor
This month, for a change of pace,
we are presenting a Social Stud-
ies program to help students
become more familiar with our U.S.
presidents. Our main problem in devel-
oping this program was how to present
the material. This was more an educa-
tional problem than one of program-
ming.
We found that many junior high
school and even some high school
students who field-tested our ideas were
totally unfamiliar with close to a dozen
of our presidents. Some of our less
popular presidents had completely
eluded these students' school careers.
Wc hope to remedy that deficit.
The easiest way of presenting the
presidents would have been to match
their names with their order of presi-
dency, for example, "James Monroe-5,
Zachary Taylor- 12," and so on through
the list. The problem with this approach
is that only a person with both an
excellent memory and an extreme inter-
Steve Blyn leaches both exceptional
and gifted children, holds two master's
degrees and has won awards for the
design of programs to aid the handi-
capped. He owns Computer Island and
lives in Stolen Island. New York.
est in the topic could possibly succeed
in such a program. We met no such
interested individual.
We decided, therefore, on the ap-
proach of asking which president came
before the one in the question. We give
a president's name and his years of
presidency. The student is then asked to
choose which of three other presidents
immediately preceded the one in ques-
tion.
The three choices are randomly se-
lected. We could have modified the
program to select three other presidents
who were in a close time-frame to the
president in question, but we purposely
did not do this. We felt this would be
too difficult. Being randomly chosen,
one of the three usually turns out to be
obviously incorrect. For example, Rea-
gan would be a silly choice for the
president who preceded Truman.
This feature serves to give an alert
student an edge in figuring out the
correct answer. He can reduce the
possibilities often to two and sometimes
even to one. This process of elimination
helps reinforce the student's knowledge
of the presidents. On the other hand, the
student who is really lost in this game
will not be able to benefit by even two
obviously incorrect choices.
The programming of this game is
quite straightforward. There have been
40 presidents, and this is reflected in the
DIMENSION statement in Line 40. Lines
50-70 read all of the presidents' names
and years in office. These are contained
in the DATA lines beginning with Line
390.
Lines 120-220 select and print out the
question and the three choices. Variable
X keeps track of the correct answer.
Lines 230-250 prevent any duplication
of names. Line 290 asks for the student's
answer, which becomes variable A.
Lines 310-320 check and print out the
correct answer. Line 330 prints out the
current scoreboard. Line 340 prints out
the final score. Line 350 asks if you
would like to go again. If the ENTER key
is pressed, the game begins again. If the
E key is pressed, the game is ended.
We hope that those of you who use
this program in a classroom as well as
those who use it at home will enjoy
playing this game. While we do not
really expect or even hope that anyone
will memorize all of the presidential
information, wc do expect that each will
learn more factual information on his
own level about some of our presidents.
As always, I enjoy hearing from readers
about my articles and programs. □

THE RAINBOW February 1987
GRAPHICS UTILITY
Color Text is a machine lan-
guage utility that gives your
CoCo something it really needs:
a better text display. More specifically.
Color Text gives colored text, text with
graphics, redefinable characters and
lowercase characters. It requires Ex-
tended Color, Disk BASIC. It runs on a
1 6K machine, but can take advantage of
32K and even 64K.
To get Color Text up and running,
enter Listing 1, which contains the
character set. This program creates a
file called CHAR5.
Next, you need to enter and run
Listing 2. Don't worry about merging
CHARS and CDLRTEXT, since Progload
combines them for you.
Now you have a file called COLR
TEXT, which is the program.
To execute CDLRTEXT you should use
the loader included in Listing 3. If you
do not want to use the loader, CDLR
David Billen lives in Nashville, Term,
and is a system software designer for
Gibson Guitar Corporation.
TEXT can be executed on a 16K. system
by entering:
CLEAR200 , &H34FF : LOADM"COLRTEX
T":EXEC
or on a 32K system with the line:
CLEAR200 , &H74FF : LOADtTCOLRTEX
T",&H4000:EXEC
The loader is self-explanatory and
accommodates loading COLRTEXT into
the upper RAM bank on a 64K system.
The program is position independent,
meaning it can be loaded anywhere in
memory.
Color Text is actually so compatible
with BASIC that there is not much to
explain. The text is on the PMDDE 4,1
graphics screen to begin with. The text
automatically adjusts itself to all graph-
ics commands, including COLOR,
SCREEN and PMODE.
Since, in the Hi-Res modes, Color
Text uses a 32-by-24 screen, the PRINTS
function's range has been expanded to
accommodate this. CLS has also been
modified to work with Color Text.
You can no longer type CLS followed
by a number representing the color you
want the screen to clear to, but you can
type CLS followed by the ASCII code
of a character you want the screen
cleared with. So, for example, CLS42
would fill the screen with asterisks and
home the cursor.
There are also several control charac-
ters that affect the display.
A list of control characters follows:
Character
4 —
6 —
11

Function
Toggles scroll lock. (Scroll
lock keeps the screen from
scrolling up when a charac-
ter is printed at the bottom.)
Inverts the character at the
current cursor location,
without updating the posi-
tion of the cursor.
Inverts the screen.
Clears the screen.
Terminates Color Text.
Of course, the standard characters 8
and 13 do their thing too.
There really is not much more to say!

in the 16K mode. This also means you
don't need to boot it before running the
definer.
The purpose of the character definer
is to create and modify characters to
your own likes/ needs. The menu has an
option to save them and an option to
save as loader. As a rule, when you are
working on a character set, you should
save them. Then, to actually use the
character set, select "save as loader."
You are asked for the name. This file
will actually be Color Text, both pro-
gram and character set. If you want to
use the boot program to load it, you will
have to save it with the name COLR
TEXT, or modify the boot program.
The menu also has an option to warm
boot and cold boot. Warm booting
simply terminates Color Text. A cold
boot leaves your computer in the state
it's in when you first turn it on.
If you select Design, you will first
select the character to be modified.
When selected, its image is brought up
on a big PMODE0,1 screen. To alter it,
move the blinking cursor with the arrow
keys. Press the space bar to toggle the
color of a block. Press ENTER when
finished, or CLEAR to abort.
Here comes the trickiest thing there
is to know about Color Text. When it
prints the characters in a four-color
mode, it only looks at (from left to right)
the second, fourth, sixth and eighth bits.
In a two-color mode it uses all of them.
Your character set must be designed
accordingly. □

ycldraw demonstrates some
of the best features of the
new CoCo 3 — a high
resolution screen with 16 colors and
color text, a PALETTE command to
change those colors at any time (you choose
from 64 possible colors), a BUTTON function for
easy access of the joystick buttons, an ON BRK
GOTO (on break) command and an ON ERR
GOTO (on error) command.
Cycldraw is a symmetrical drawing program. What you
draw in one quadrant of the screen is duplicated in the
other three screen quadrants (a kaleidoscope effect). Also
the palette of colors is continously changing ("color
cycling") as you draw, demonstrating a fascinating feature
of the new CoCo.
All you need to do is CLOflD'TYCLDRRW, use the
right joystick and follow the instructions you see on your
screen. Happy Cycling!

EDUCATION OVERVIEW
Do Teachers Like Computers?
By Michael Plog, Ph.D.
Rainbow Contributing Editor
Many studies in the past have
looked at the numbers of
computers in schools. In this
column, we have reported the growing
number of machines available to stu-
dents and teachers. With such unusual
growth, most people now accept that
computers have an important role to
play in schools. The type of role, how-
ever, will depend in large part on how
teachers use computers and how
teachers view the effectiveness of com-
puters.
There has not been much study of
how teachers view computer use in
schools, or of teacher attitudes about
computers. One study, however, was
conducted by H.J. Baker and reported
by the U.S. Department of Education,
Center for Educational Statistics. Bak-
er's study was based on 2,700 question-
naires sent to teachers in all grade levels
throughout the country. Questionnaires
were returned by 80 percent of the
teachers (2,160) — a return rate that is
very impressive for mailed surveys.
In addition to asking how the
teachers use computers, eight questions
were asked about teacher attitudes
toward computers. The questions,
along with the percent of each response,
are presented in the table.
Most teachers (82 percent either
agreed or strongly agreed) fell that
computers can help teachers teach more
effectively. Thirteen percent had no
opinion about the question. This indi-
cates fairly strong support for educa-

degree from the University of Illinois.

school, worked in the central office of

Education.
tional uses of computers by teachers,
even by non-users. Just considering
those who provided an opinion (elimi-
nating the "No Opinion" group), about
95 percent agreed or strongly agreed
with the statement.
Since any educational activity is
dependent on teachers, this support is
crucial for computer use in schools. If
teachers do not support using machines
for educational purposes, then any
efforts by administrators will collapse.
A potential positive teacher attitude
for classroom computers may also be
demonstrated by the second question
about disruption to classes. Thirteen
percent of the teachers thought having
one or two students working on a
computer would disrupt the rest of the
class, while 63 percent thought it would
not be disruptive. Nearly one-fourth (24
percent) had no opinion about disrup-
tion.
One possible explanation for the
large number of "No Opinion" re-
sponses is the use of computer labs in
schools. Many teachers who have stu-
dents use computers do so in a lab
situation; computers are not available
in classrooms. Thus, some teachers mav

never have been in a position of having
students work on a computer while
something else is going on in the class-
room.
In one sense, the question of disrup-
tion is not very powerful for measuring
teacher attitudes about support for
computer uses in schools. 1 used the
term "potential positive teacher atti-
tude," but another factor is involved
besides teacher acceptance of comput-
ers — teacher style. Some teachers want
all students in the class to be doing the
same work at the same time. Other
teachers encourage, even thrive, on a
variety of activities in the same physical
space at the same time. It is possible that
some of the "all the same" teachers have
a very positive attitude toward educa-
tional use of computers, but do not
want a few students away from the
lesson and working on computers. It is
also possible that some of the "different
activities at the same time" teachers do
not think any disruption would occur in
their class if a few students were work-
ing on the machines, but do not have a
positive attitude toward computers.
Thus, it is difficult (maybe impossible)
to gauge teacher attitudes by this ques-
tion.
An overwhelming majority of
teachers (90 percent) said they want
more computer training. Four percent
said they do not want more training,
and 7 percent had no opinion on the
question.
It is possible, of course, that the 4
percent of teachers not wanting more
training support computer use in
schools, but feel they already know
enough. While possible, this is unlikely.
It is much more probable that this 4
percent represent teachers who feel no
need for computer use in their classes.
One of the features of computer knowl-
edge is that mastery is never totally
achieved. There is always additional
software to learn, extra "helpful hints"
to file away, and even new machines to
examine.
The next survey question, about
quality of software, does not appear to
be a very productive item. Nearly half
of the teachers (49 percent) did not
express an opinion about the question.
Of those who did have an opinion about
software, about twice as many (35
percent compared to 17 percent)
thought available software is instruc-
tional^ good.
It seems to me that teachers can fall
into three broad categories: those who
have examined almost no educational
software; those who have examined a
little bit of software; and those who are
familiar with a lot of software. The
question, as stated, is somewhat inap-
propriate for teachers with very limited
or very great experience with software.
Those who have very limited experience
with software cannot really answer the
question. Teachers who have examined
a great deal of software have probably
seen some very bad materials and some
very good materials; it would be diffi-
cult to respond to the question.
About half of the teachers surveyed
(51 percent) said they feel comfortable
working with computers. Nearly one-
third (31 percent) said they do not feel
comfortable. It is interesting to note
that whether teachers feel comfortable
with computers or not, most still want
more training. This question is proba-
bly the single most changeable item on
the whole survey. Teachers are contin-
ually receiving in-service instruction on
computers, sponsored by school dis-
tricts, regional centers, computer con-
sortia and state education agencies.
Each month, a few more teachers will
feel comfortable working with comput-
ers. Naturally, there will always be a few
teachers who are not comfortable with
computers and who will have minimal
use of the machines in classes. But, that
number will decrease with each succes-
sive year.
Nearly all respondents to the survey
felt that teachers should preview soft-
ware before purchase. I wonder why 9
percent of teachers had no opinion on
this item and 1 percent disagreed. Could
they be thinking of review by school
people other than teachers, such as
administrators, parents or students?
If you want to start a spirited discus-
sion in a teachers' lounge, make the
comment, "Integrating computer time
with other subject areas is a fairly simple
matter." About one-third of the re-
spondents to the survey (32 percent)
agreed with the statement; about one-
third (33 percent) disagreed; and about
one-third (34 percent) had no opinion.
The degree of ease or difficulty of
integrating computers with other sub-
jects may be related to several factors:
particular subject matter taught, age
and abilities of students, degree of
knowledge and creativity of teachers,
and quality of available software.
About half of the teachers (51 per-
cent) said the equipment is not difficult
to use; only 8 percent said it is. This
leaves 41 percent without an opinion.
Are the "No Opinion" people those who
have not used computers, or those who
realize some equipment is easy to use
and some is hard to use?
In conclusion, it seems there are some
generalizations from this study that
would be worthwhile for educators to
consider. First, in-service training about
computers is still important for
teachers. A small amount of that train-
ing should be for operating equipment.
The bulk of the training should concen-
trate on two major topics: suggestions
for integration of computers into sub-
ject matter areas and selection of edu-
cational software (possibly including
sessions of "what makes a good soft-
ware package").

SIG Changes Include New
Selections, New Sections
By Cray Augsburg
Rainbow CoCo SIGop
Several changes have taken place
on the CoCo SIG. First, the Sub-
scriptions menu has been
changed to "Rainbow Magazine Servi-
ces." To enter this area, type R at the
CoCo SIG prompt. To make things
more logical, the "Order RAINBOW-
fest Tickets" and "Address Change"
selections have been moved from the
Questions & Feedback section to this
new section. The new section includes
a selection, "Ask The Experts," for
sending mail to Marty Goodman, Dan
Downard or Richard Esposito. Just
select the person you want the technical
question to go to and then fill in the
blanks. You will be asked for your name
and address and then be given plenty of
space to ask your question. We believe
this will help us get your questions
answered in a timely manner.
Another change has come about that
has somewhat altered the SIG structure
as we knew it before. To better handle
the increasing interest in OS-9, we
decided to create a new SIG directly
pertaining to the OS-9 operating sys-
tem. While designed for CoCo OS-9
users, it can be used by OS-9 68 K users,
too, and even has a database topic set
aside for such computers. This new area
can be reached by typing 0S9 at the
CoCo SIG prompt. Once in "OS-9
Online," you will be greeted with the
menu. This new SIG includes a Forum
and a Mail section, and most impor-

assistant and has an associate 's degree

tantly, its own database area. This
database area is separate from the
normal CoCo SIG database area. This
will make it easy for those interested in
OS-9, since the database area will have
16 topics corresponding to more spe-
cific aspects of OS-9.

Several people have said they were
DATABASE REPORT
To further assist us with providing
our membership with prompt,
expert advice, we have enlarged
our staff complement of OS-9 experts.
Greg Law (gkegl) now joins Dale Lear
(dalelear) and Rick Adams (RICKA-
DAMS) as part of our Delphi OS-9 staff.
Greg has many years of experience with
OS-9. and is a c and 6809 assembly
language programmer as well. Welcome,
Greg!
We have quite a treat in store for you
OS-9 Level 1 users. Mike D/iedzic (MJD)
has sent us a set of drivers for the 80-
column screen of the CoCo 3, to be used
under OS-9 Level I Version 2.0. Along
with the addition of material from Kevin
Darling (kdari.ing), this should be a
very popular set of files. These can be
found in the OS-9 section of the CoCo
SIG database or, if "OS-9 Online" is open
by the time you read this, in the Drivers
section of this new OS-9 SIG.
We haven't forgotten all you RS-DOS
users, though. For all CoCo RS-DOS
users we have a treat in store: Greg Miller
(GREGMtLLER) who. with Erik Gavriluk
(erikgav), brought us Mc Paint, has
kindly uploaded his CoCo terminal
program Greg-E-Term. GEterm runs on
all models of CoCo. On the CoCo I and
2 it supports either the bit-banger or the
hardware RS-232 pak.
It offers screen display options of 32,
5 1 , 64, or 85 columns, or support for the
Word-Pak II (and with soon-to-be-
posted minor patches, support for the
Word-Pak I and Word-Pak-RS as well)
and the double-density, 80-column
board. It works perfectly for Xmodem
up- and downloading at 1200 baud
through the bit-banger port. Of course,
its terminal mode function in full duplex
at 1200 baud through the bit-banger is
less than perfect, but it is usable.
GETerm supports the 32-, 40- and 80-
column display of the CoCo 3 as well,
and has special routines written explicitly
for the CoCo 3 to use its better bit-banger
port at 1200 baud more smoothly than
any CoCo I or 2 program ever could. It
also features viewing and marking of its
buffer, and the use of both FIND and
formatting commands for navigating in
and printing the buffer.
GETerm comes with a configure pro-
gram, a help file, and two documentation
files that total over 540K of information
on the program. This is a major new
"guillware" terminal program entry into
the CoCo world. Believe me, this is a
must get program. It is well worth the
time needed to download all 50K or so
worth of material in the GETerm group.
GETerm is to be found in the Data
Communications section of the CoCo
SIG. The CoCo Community owes Greg
Miller a big thank you.
Greg's partner, Erik, has not been
loafing either. He has sent us a version
of the Macintosh Picture Converter for
the CoCo 3. This program allows you to
download a Macintosh picture file from
Macintosh-oriented BBS systems from a
friend with a Mac, and then view it on
the CoCo 3. The CoCo 3 version of the
Mac converter displays the full horizon-
tal width of the Mac image, though of
course it has to scroll through the full
vertical height of the larger Mac pictures.

unable to log onto Delphi at eight bits,
no parity and one stop bit. After check-
ing into the matter, we discovered some
features of Telenet that should help. If
you are accessing at 300 or 1200 baud,
when a connection is achieved, press
ENTER, then type D and press ENTER
again. Note that the 'D' must be upper-
case. Then proceed to log on as usual.
If you are accessing Delphi at 2400
baud, when a connection is made, type
@D and press ENTER. Again, the 'D' must
be uppercase. As an aside, if you are
using a terminal package that features
VT-100 emulation, you can type Dl
(uppercase 'D') and press ENTER at the
"Terminal=" prompt. This will tell
Telenet you want to use VT-100 emula-
tion.
More on Settings
The Xmodem settings area (in the
Settings area of your Workspace) lets
you set four different parameters re-
garding how you want the system to
handle Xmodem Tile transfers. They are
"Error Check Mode," "Last Block
Handling," "Retry Count" and "Time-
out Period."
Two types of Xmodem error checking
are available on Delphi: Checksum and
CRC (Cyclic Redundancy Check).
Checksum error checking has been
around for a long time and is the most
common method, so any terminal pro-
gram that supports Xmodem will sup-
port this method of error checking.
Because of this. Checksum is the default
error-checking method on Delphi.
However, CRC error checking is con-
siderably more accurate. If your termi-
nal program happens to support this, by
all means use it. In any event, the error-
checking selection you choose only
affects uploading. For downloading,
Delphi automatically adjusts itself to
the mode requested by your terminal
package.
The "Last Block Handling" option is
of little consequence to most users. It
lets you set how the last block of an
Xmodem text download is handled by
the system. In the "Normal Handling"
mode, which is the default, the last
block is padded with null characters to
fill it out to a standard 128-byte Xmo-
dem block and a CONTROL-Z is sent to
close the file.
Two other methods for handling the
last block are available; "Atari Mode,"
which is obviously for users of an Atari
microcomputer, and a "No CONTROL-
z" mode for users of certain Apple
computers.
Of more direct importance to users of
the CoCo SIG are the "Retry Count"
and "Timeout Period" Xmodem set-
tings. The Retry Count is the number of
times the system tries to recover from
The Macintosh Picture Converter for the
CoCo 3 can be found either in the CoCo
3 News section or, more likely by the time
you read this, in the Graphics database.
Art Flexser (artflexser) has sent us
patches for modifying Colorcom/ E to
work on the CoCo 3. These will be found
either in the CoCo 3 News section or in
the Data Communications section of the
CoCo SIG.
Why the uncertainty on my part about
where to find some of these files? By the
time you read this, we will be taking apart
our CoCo 3 News and Information topic
area and moving most of the files in it to
the other topic areas on the CoCo SIG
database. As we move each file, if it is a
CoCo 3-specific file, we will flag it with
"(C3)" in the group name title, and will
give it a keyword of C3, to allow you to
scan the other databases to look for
CoCo 3-specific files. This change is
being implemented during December
and January, and should be completed
by the time you read these words.
In the CoCo 3 News and Information
database (or, more likely, in other ap-
propriate databases by the time you read
this), we have from Steve Bjork (6809ER),
New Boot, a program to allow owners of
Ghana Bwana, Desert Rider and One on
One the ability to fix CoCo 3-
incompalibility problems in these games,
and manipulate the color set. Jim Shoop
(bazar) has provided a patch for some
versions of VIP Writer to make it run on
the CoCo 3. Bob Wharton (BOBWHAR-
TON) sent us a color-bar utility and an X-
MAS newsletter for the CoCo 3, and
Kevin Darling has sent us a text file with
yel more information on the working of
the GIME chip, including a full pin-out
of it. Bill Jackson (B1LUACKSON) pro-
vided a printer spooler for the CoCo 3,
and Damon Hill (dwhill) has sent us an
interesting Microware press release.
Frank Hogg (E HOGG) of Frank Hogg Lab
has also given us a text file telling us of
his company's plans to support the CoCo
3 under OS-9 Level II. Loren Howell
(XENOS) has sent us a CGP-220 screen
dump program. He also has given us a
CoCo 3 drawing utility called h doodle.
Roger Bouchard (harbie), our official
CoCo 3 basic Bug Finder and Swatter,
has sent us an update to his previous file
of CoCo 3 basic bugs and fixes for them.
Michael Fischer (MIKE88) has given us
some "Fun Pokes" for the CoCo 3, and
Steve Macri (DRACMAN) has sent us his
Kellybook program. Gene Loefer
(Gl.OEFER) has given us an RGB
palette utility. Mike Dziedzic has pres-
ented us with a real tour de force: An M L
program that displays all 64 RGB palette
colors on the CoCo 3 screen at once
(using the same sneaky trick that Rick
Adams used in his article in rainbow).
Doug Masten (omasten) has sent us a
lowercase utility. Al Gengler (AJG) has
sent us a utility for calculating HBUFFER
sizes. Andrew Ellinor (cropper) has sent
us CC3 Start, containing some stan-up
pokes for the CoCo 3 BASIC. Derrick
Kardos (DTG) has also sent us some
CoCo basic programs.
Finally, in this area (or in the Hard-
ware Hacking area). I have uploaded for
hardware hackers a fascinating file that
contains a complete description of ex-
actly what goes on inside the new Tandy
PAL chip for the older multipacks. Bob
Lentz (president of the Microworks,
makers of Macro 80C Assembler and the
DS-69 and DS-69A digitizer for the
CoCo) "read" that PAL chip, and has
provided us hackers with invaluable
information on just what it does.
As staled above, it is likely that all the
material currently in the OS-9 section of
the CoCo SIG will be moved to OS9
Online by the time you read this. So you
may have to look around there in an
appropriate topic section to find the
following material. As I write this, the
following new material has arrived in our
OS-9 area: Kevin Darling has sent us an
"SCF Editor Plus." Rick Adams, one of
our staff and author of the famous MONO
command for OS-9 on the CoCo 3, has
gone one better and given us a COLOR
function to change the text colors on the
CoCo 3. Mark Sunderlin (megabyte)
has sent us a mammoth amount of mate-
rial on his favorite error-checking/ error-
correcting protocol, Kermit. This in-
cludes a Kermit program for the CoCo
under OS-9, and complete tech specs on
the Kermit protocol. Dan Connolly
(CONNOLLY) has provided a grouping of
files that includes instructions on modi-
fying the hardware of some Word-Pak I's
and IPs to allow them to have their ports
moved to the same address as that of the
Word-Pak RS, thereby making them
compatible with the CoCo 3 Mullipak.
He also provides driver software for the
the Word-Pak in this group. Ronald Cole
(ronaldcole) has sent us a fix for the
OS-9 Level I Version 2 clock module.
In the Utilities section of the CoCo
SIG, Paul K. Ward (PKW) has sent us a
very professional review of relational
database programs, a field he has consid-
erable expertise in. Kenneth L. Wuelzcr
(wuelzerken) has sent us an update to
his amazing KDISK editor, that edits RS-
DOS, MS-DOS, and Flex disks. Chris-
topher Rak (dunsel) has sent us a disk
index program. Jim Zito (J1MZ) and
Steve Fabiszak (sjfraf) have also sent
us utilities.
In the Graphics database, Greg Miller
has sent us an Atari ST picture converter,
that allows a CoCo to download and

a bad data or timeout error before
giving up and aborting the Xmodem
transfer. This can be set to any number
between one and 127. The system de-
fault is 10 retries.
The "Timeout Period" parameter
dictates how long the system waits for
you to send a block during an upload,
or how long it waits for a reply after
sending your computer a block during
a download. In either case, if the time-
out period expires before the system
receives the appropriate response, a
timeout error is recorded internally and
the block is transferred again.
The system default for timeout is 15
seconds, but can be changed to any
number of seconds between one and
127. If you often experience timeout
errors during Xmodem file transfers,
you may want to increase this number.
Also, Delphi users in other countries
will probably want to select a long
timeout period because of multiple-
network delays. Decreasing the timeout
period will generally result in faster
recovery from errors during a transfer,
but may also cause unnecessary errors
to be generated.
That's it for this installment of Delphi
Bureau. We will try to devote a little
more space to other advanced settings
in Workspace next time. □

busy this last month. Those of us on the
staff here want to thank all of you who
have ever contributed or dropped by, for
your help and patronage. A few days
after I send this article to rainbow we
will have passed the 20,000 mark in
forum messages, and will be the first
Delphi SIG to do so, [Michael Fischer,
of Great River, NY, posted the 20,000th
message on December 12.]
I am extremely pleased with the suc-

Submitting Material
To Rainbow
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.
Program submissions must be on tape or disk and
it is best to make several saves, at least one of them
in ASCI I format. We're sorry, but we do not have time
to key in programs. All programs should be supported
by some editorial commentary explaining how the
program works. Generally, we're much more inter-
ested in how your submission works and runs than
how you developed it. Programs should be learning
experiences.
We do pay for submissions, based on a number of
criteria. Tnose wishing remuneration should so sfafe
when making submissions.
For the benefit of those who wish more detailed
information on making submissions, please send a
self-addressed, stamped envelope (SASE) to: Submis-
sions Editor, THE RAINBOW, The Falsoft Building, P.O.
Box 385, Prospect, KY 40059. We will send you some
more comprehensive guidelines.
Please do not submit programs or articles currently
submitted to another publication.
Hint
Delay Play
1 have found an interesting way to utilize the
P0KE&HFF21,&H3C and P0KE&HFF21 ,&H34. For
those who don't know, these pokes turn the cassette
motor relay on and off, respectively. You can use this
to alter the way a tape sounds. Put a voice or music
tape in your recorder and unplug all computer plugs
from the recorder except the remote plug. Then run
the following program:
10 INPUT~SPEED";fi
20 P0KE&HFF21,&H3C
30 FOR X=l TD A:NEXTX
40 P0KE&HFF21,&H34
50 GDTD20
Since the value for A is a delay factor, the larger
A is, the slower the tape will be played back.

DISK UTILITY
The Limousine Utility:
A Tape-To-Disk
Transfer Vehicle
(This article first appeared in the January 1984 issue of
THE RAINBOW. Due to its popularity and to the advent of
our RAINBOW ON DISK service, we are reprinting this useful
utility.
While this reprinting is something of a first, it is a special
case because the issue of the magazine in which it appeared
is out of print and back issues are no longer available.
This does not, by any means, signal any intention to
"recycle" other material from previous issues.)
By Roger Schrag
When lots of folks first get a Color Computer, they
hook up a cassette recorder to save their pro-
grams, figuring they will get a disk drive later on.
By the time they do get a disk drive, they have accumulated
a large library of programs and data files on tape.
It then becomes something of a chore to transfer ail of
those files from tape to disk. A BASIC program needs to be
loaded from tape and saved to disk. A machine language
program needs to be CLOflDMed from tape, analyzed so that
the addresses may be found, and finally SflVEMed to disk.
Transferring data files, meanwhile, can often be a total
nightmare.
What 1 would like to present here is a simple tape-to-disk
file transferring utility. The source code is shown in the
program listing, and may be keyed in and assembled with
most any editor/ assembler in a straightforward manner.
In short, this utility will read just about any standard tape
file and transfer it to disk. The disk file will have the exact
same attributes (BASIC or machine language, ASCII or
binary, etc.) as the tape file, and the disk file will be fully
loadable and operational.
Since this utility uses three undocumented routines in the

University of California at Berkeley, enjoys working with
CoCo and writing articles for THE RAINBOW.

disk ROM, it may not work on systems
with other than Radio Shack Disk
BASIC. It checks to see which version of
the disk ROM you have, and then
branches to the appropriate address.
To transfer a file from tape to disk,
load the assembled program and exe-
cute it. The screen will clear and you will
be prompted to prepare the cassette
containing the file to be transferred and
to press ENTER. Cue the tape to the
beginning of the file and press ENTER.
The tape's sound will be played over the
TV's speaker to aid you in locating the
recording on the cassette. If you cue the
tape badly and the tape starts out in the
middle of the file, don't worry; simply
reposition the tape to the beginning.
The transfer utility will sift patiently
through the middle of a file, or even
through garbage, until it finds what it's
looking for.
When the transfer utility does find the
beginning of a file, it will stop the
recorder and print the file's name and
type. You will be asked if you want to
transfer this file. If you do, press the Y
key. Otherwise press the N key. You will
be prompted to prepare the cassette
again.
As the file loads in, a block will blink
in the upper-left corner of the screen. If
there isn't enough memory to hold the
whole file, or if there is an I/O Error,
a message will be printed and the
transfer terminated. You will then be
invited to start the transfer utility over
again or return to BASIC.
BASIC programs saved in non-ASCII
form and machine language programs
saved with the CSAVEM command are
organized differently on disk than on
tape. So when the tape file is fully
loaded into memory, the transfer utility
will automatically reformat the data as
needed so that it will work correctly on
disk. (BASIC programs saved in ASCII
form, data files and machine language
programs created by EDTASM+ don't
need any modifying.)
When the tape file is finished loading
and reformatting is complete, a message
to this effect will appear on the screen.
You will now be asked for the name you
want to give to the disk file. Enter any
filespec that is valid in BASIC but don't
enclose it in quotes. If you don't specify
an extension, none will be used, and if
you don't specify a drive number, the
default will be used.
The transfer utility will next save the
file onto disk. If an error occurs any-
where along the way, a message will be
printed and you will be prompted again
to enter the name for the disk file. So,
if an error occurs while saving to disk,
you won't have to reload the tape file
all over again.
When the file has been successfully
saved on disk, you will be asked if you
would like to start the transfer utility
anew. If you have more tape files to
transfer, then press the Y key. Pressing
the N key will return you to BASIC.
At any time the transfer utility is
waiting for keyboard input, you may
press BREAK to cancel the transfer in
progress. You will then be asked if you
would like to start over again or return
to BASIC.
This utility will transfer any BASIC
program, basic program saved in
ASCII, machine language program
created by CSAVEM, machine language
program created by EDTASM+, or just
about anv data file to disk easily and
accurately. It may not transfer protected
programs or automatic execute loaders,
however.
One interesting note: On cassette,
there is no distinction between data files
and BASIC programs saved in ASCII.
That is, there is no way to tell whether
a file was created with the command
OPEN"0" ,-Vfilename" or with the
command CSAVE" filename" , PI. What
does this mean? If you use the utility to
transfer a BASIC program saved in
ASCII, you will be told that the file is
a data file, even though it is actually a
BASIC program. There is no harm in
this, however, because the disk file
created will load correctly with the LOAD
command, in spite of being labeled as
a data file.
All files created by the Color Com-
puter start out with a I5-byte block of
data called a "header." The header
contains the filename, the file's type,
whether it is in ASCII or binary, and
whether the tape recorder must be
turned off and back on between loading
each block of code. This leaves four
bytes that are usually unused. The one
exception is in machine language pro-
grams saved by the C5AVEM command.
Here, the last four bytes contain the
program's start and execute addresses.
The transfer utility uses all of the
information in a file's header to load it
properly and reformat it if necessary.
Some of this information is then trans-
ferred into the disk director}'.

THE RAINBOW February 1987

Color Computer 3 Is Top Dog
at Princeton RAINBOWfest
li was a cool evening in
Princeton, New Jersey, when
literally thousands descended
upon the local Hyatt Regency
hotel. "What's going on?" was
heard from several passers-by.
What else?? It was the 12th
RAINBOWfest. It was the pre-
mier show for the new Color
Computer 3. At 7, Friday even-
ing, the vendors were ready and
the doors were opened.
There was a mad dash for the
Radio Shack booth; everyone
wanted to get a glimpse of the
new machine. For many, it was
the first look at the CoCo 3. As
the night went on, it became a
common sight to see people
purchasing their CoCo 3s, tuck-
ing them under their arms, and
heading off to their hotel rooms
to see what they needed to do
to the hotel's TVs to make their
CoCo 3 work. It was somewhat
reminiscent of the "Cabbage
Patch" craze. Later, after an
hour with the new machine.
those people would reappear in
the exhibit hall to see what
other things they could find.
To put it in simpler terms, the
Color Computer 3 was the bit
of the show. Few could speak of
anything else. Questions and
rumors were flying. To offset
this, the show was attended by
Barry Thompson, Mark Siegel,
Fran McGehee and Srini
Vasan. These representatives of
Tandy Corporation did their
best to answer all the questions
people had. Barry Thompson
and Mark Siegel were also
panel members for the round-
table discussion on the CoCo 3.
People appeared in the ex-
hibit hall in waves. Just as you
started to move down an aisle,
it would crowd up and you
would be blocked.
Several groups of people ga-
thered outside the exhibit hall
just so they could talk with each
other.
While excitement about the
Around 500 Color Computer .Is fa sell-out) were taken home by the crowd
tit RAINBOWfest Princeton 19X6.
CoCo 3 was high, several "out-
side" discussions turned to a
more serious matter; how best
to support the enhancements of
the new machine. A great topic
was the exchange of technical
information. (As more and
more producers of CoCo soft-
ware get their new machines, it
is becoming quite apparent the
support is there. We are already
seeing new products on the
market designed to take full
advantage of the CoCo 3.)
It appears that many people
are taking heed of CoCo Com-
munity Breakfast keynote
speaker Dale Lear's charge that
we move forward with CoCo 3
and be innovative.
We should see a great deal
more on the CoCo 3 at the next
RAINBOWfest which is sche-
duled for April 10-12, 1987 in
Chicago.
Owl-Ware Has Everything for the CoCo Hacker
Greg H'ozricki of Owlware finalizes another sale.
Owl-Ware was out in force
selling everything from AC
power centers to complete hard
drive systems. Prices for the
hard drive systems, which in-
cluded Winchester BASIC, var-
ied from $599 for 10 Meg to
S829 for 30 Meg. Owl- Ware was
also selling full-height, double-
sided drives for $89. They also
sold twoTandv 1200s with hard
drives for $895 each.
About the RAINBOWfest,
Tom Roginski, owner of Owl-
Ware, said, "These are nice,
honest people. Very good to
work with. Generally, I think
everyone is enjoying the show."
In addition to drives, Owl-
Ware had a full line of compo-
nents and computers.
When the show ended Sun-
day, Tom demonstrated a little
hardware device Owl-Ware had
been working on. The Super
I/O Board is a cartridge-like
add-on for the CoCo 2 and
CoCo 3, which includes two
serial ports, a parallel port and
a real-time clock as well as
extending the cartridge port for
the disk controller. It is de-
signed to work under OS-9. It
should be a real boon for OS-
9 hackers.
Computer Plus —
Great Bargains on
Tandy Equipment
Computer Plus occupied two
booths at the Princeton Test.
The hot item was the Color
Computer 3 selling for $169.
Computer Plus sold out of their
CoCo 3s by noon on Saturday.
In addition, several people look
advantage of the opportunitv to
buy the DMP-105 for $1 10 and
the DMP-130 for $210.
Another hot item was the FD-
501 disk drive system, which
was selling for $170. Fran Pur-
cell, owner of Computer Plus,
said, "The crowd seems larger
than usual. Financially this is
the best RAINBOWfest ive've
ever been to,"
February 198? THE RAINBOW 83
Radio Shack — Consumer Division
Takes Over Booth Management
At the Radio Shack booth,
we spoke with District Man-
ager Hank Boyer. That is, we
tried to speak with Hank, but
every time the conversation
started, he would have to run
off to write up another sale.
People pressed around the
Radio Shack booth watching
the CoCo 3 and CM-8 do their
thing. Radio Shack was selling
the CoCo 3 for $ 199 and taking
prepaid orders for the CM-8 for
S259.95. Other bargains in-
cluded the FD-501 drive system
for $ 1 70, 64K CoCo 2s for $85.
I6K Standard CoCo 2s for $49,
Deskmate for $59.95 and the
Color Mouse for $29.95. When
the Show opened Sunday,
Radio Shack dropped the price
of the CoCo 3 to $179 and
shortly sold out. Hank told us,
"The Tandy Business Products
Division used to run the Radio
Shack booth at the RAIN-
BOWfests. Now, the Consumer
Division has taken over the
responsibility and we hope to
be doing many new things in
future shows."
RAINBOW Publisher Lontlit Folk
Breakfast speaker Dale Lear.
Heft) thanks CoCo Community
Radio Shack District Manager Hank Boyer responds to a question.
OS-9 Users Group —
More Popular Than Ever
Several heavy discussions
were started at the OS-9 Users
Group booth. In between sign-
ing up new members, Brian
Lantz, president of the Users
Group, said, "There appears to
be a high interest in OS-9. We
have taken twice as many mem-
berships as we have at previous
RAINBOWfests." At the OS-9
Users Group breakfast Sunday
morning, Esther Puckett, wife
of Dale Puckett, was unani-
mously voted in as a lifetime
honorary member.
Disto's Many Marvels Include CDOS 4.0
At the Disto booth we spoke
with Chris Roshon, who ap-
peared to have taken over sales
since Tony DiStefano was al-
ways caught up in explaining
his "many marvels'* to the ever-
present crowd. Chris said, "We
are enjoying the show very
much. We especially liked the
round-table discussion. It's
good to meet the people who
control the CoCo's destiny in
Fort Worth."
On a nearby table, CoCo
Max was running on a CoCo 2
and people were loading full
CoCo Max pictures in a flash.
Tony had done it again. In a
system running CDOS 4.0. it is
possible to load CoCo Max
files from the Disto RAM Disk
instantly.
Disto was selling the con-
troller for $80 and the Display
80 add-on for $110. Also,
RAMDisks were pretty inex-
pensive, as the 256K model sold
for $90 and a full 5 1 2K card was
going for $130.
RAINBOti'fest Princeton was attended by some 12,000 people.
84 THE RAINBOW February 1987
In less formal attire, OS-9 expert
Dale Lear goes online with Delphi.
Delphi Gives
Long-Distance Friends
a Chance to Meet
The Delphi booth was teem-
ing with activity as Delphi
members gathered to meet and
see what their online friends
looked like. While Marty
Goodman was busy showing
off several features of Delphi's
system, Dick Ellisco was busy
selling Telenetics Pony Express
2400 baud modems for a special
show price of $349. The mod-
ems regularly cost $500. For
several people, it was quite a
thrill to see Marty accessing
Delphi at 2400 baud. John Gib-
ney of Delphi said, "We are
letting people perceive the full
value of 2400 baud operation."
Computize: Braphicom Selling Well
Bruce Farringlon of Computize discusses CoCo 3 compatibility with
RA IN BO H'fest attendees.
At the Computize booth,
workers were busy selling
Graphicom and Graphieom
Part II. The reason for high
sales on these products is that
CoCo Max is incompatible
with the CoCo 3. People
seemed to have CoCo 3 on their
minds and wanted software
that would work on their new.
as well as their old machines.
Ken Klosinski of Computize
said, "This is the best show so
far for us." In addition to
Graphicom sales, Computize
did well selling digitizers and 'Y'
cables. The biggest item at this
booth was the Hartlcopy print-
er utility.
Southwestern Digital Has Show-End Blow Out Sale
Hot items at the Southwest-
ern Digital booth were the
Drive for $95, and serial/
parallel converters. Southwest-
ern had a show-end blowout of
drive systems, as well, with
Drive and I combo systems
complete with controller going
for an unbelievably low SI 40.
Also, complete Drive systems
were selling for $85.
Microworld: Business Booming — Onlg Vendors
to Offer CM-8 Monitors at RAINBOWfest
The two booths occupied by
Microworld were crammed
with Radio Shack hardware
and software. They completely
sold out their 200 CoCo 3s at
$169. Other items included the
Radio Shack Drive 0s for $169
and Multi-Pak Interfaces for
$75 apiece. Microworld was
also offering Deluxe RS-232
Paks for a mere $25. Being an
authorized Radio Shack Repair
Center helped, too, as Micro-
world is able to supply the
required Multi-Pak fix for the
CoCo 3.
Perhaps one of the highest
points in the exhibit hall came
when Microworld was able to
announce they had several new
CM-8 monitors for sale. At a
price of $275 each, they sold the
special shipment of 10 in less
than 15 minutes. Being first in
line really helped at this booth.
Richard Kromer, owner of Mi-
croworld commented. "We've
done a world of business this
Saturday alone."
CoCo 3s were a popular item at the Microworld booth.
Diecom Plans to Support CoCo 3
which were being sold for
$23.95. While the programs
were not compatible with the
CoCo 3, David Dies assured us
that Diecom will fully support
the new machine. To prove this
point, they were allowing ex-
changes for up to three weeks
for upgrades of their programs
to CoCo 3 versions. David also
told us to "look for newer
things in the future which will
take full advantage of the ma-
chine's enhanced capabilities."
While fewer software houses
were at this RAINBOWfest
than at previous Tests, Diecom
was there in full force. Two new
programs by David Dies, pres-
ident and programmer for Die-
com, were available. Gates of
Delirium, a fantasy role-
playing game was selling for
$31.95. Also. Bouncing
Boulders, a fast-paced, arcade-
style game, sold at $23.95.
Special show prices were also
in effect for Gantelet, Wrestle
Maniac and Marble Maze,
Howard Medical Has a Hit With Monochrome Monitors
Howard Medical was quite
busy selling monochrome
monitors from $67.50. Another
big seller was the dual mode
Epson LX-80 printer for $199.
Ross Litton, manager of How-
ard Medical, told us, "The
CoCo 3 is definitely the high
point of this show, but there
seems to be some confusion
about the CoCo 2s and CoCo
3s and which monitors work
with them. Once this is cleared
up, sales will be even better." In
any case, picking up a Comrex
color monitor for $139 wasn't
loo bad a deal, at all!

Spectrum's CC3DRAW Proves Popular
Among Hew CoCo 3 Owners
Spectrum Projects ' Paul Rosen (right) wraps up a sale.
Spectrum Projects was on
hand with all of their CoCo
products. They sold out of sev-
eral, such as Telepatch II and
Mikev-Dial. Spectrum's new
CC3DRAW was a big hit at
$19.95 as the new CoCo 3
owners wanted to get it for their
new machines. Asked what he

CoCo Community, Bob Rosen,

J & M Systems Sees
Future in New Machine
.1 & M Systems was selling its
.IFD-EC disk controller for
S49.95. This was a special show
price, down from $75. In addi-
tion, they were quite busy
showing off a pretty, little hard
drive. According to Terry John-
son, "There is lots of room in
the CoCo market for hard
drives, especially with the up-
coming OS-9 on the CoCo 3.
Basically, we are impressed
with the amount of interest in
the CoCo 3. We are using this
show to decide what we will be
doing for the new machine in
the future."
Public Domain Software
Makes 'test Debut
Don Johnson of Public Do-
main Software told us, "This is
our first RAINBOWfest and I
like it. The crowd enabled us to
let people know who we are."
Public Domain was selling
disks filled with PD software
for $5 apiece or $99 for the
complete library of 27 disks.
The normal rate is $ 1 per disk.

new Supplement to 500 Pokes.
Peeks and Execs was being sold
for $9, while the original edition
was selling for $15. On Sunday.
Microcom announced that no
reasonable offer on their pro-

HDS Does Well With
MS-DOS, Too
Kevin Franciotti, who was
manning the Hard Drive Spe-

ware vendors were missing out
by not attending the Princeton
show. In addition to their con-
troller and CoCo disk drive
sales, HDS sold quite a few of
their offerings in the MS-DOS
line.
Tom Dykema and Marianne
Hoving were definitely doing
well at the T & D Subscription
Software booth. T & D offers
one tape or disk per month for
one year for a price of $70. This
means more than 120 pro-
grams. At the RAINBOWfest,
they were offering a special
show deal of a one year's sub-
scription for $60 plus four tapes
free. Needless to say, several
people were taking advantage
of this offer.

Computer Island booth selling
everything from blank disks to
T-shirts. Steve says the educa-

wide open. To prove this point.
Computer Island promptly sold
out of several of its educational
software products.

ADOS doesn't entirely work on
the CoCo 3, most features do
work and I hope to be releasing
a version for the CoCo 3 soon."

CoCo 3 Undergoes Implant Surgery
The Computer Center was

head technician Logan Ward,
they were doing quite a bit of

which included the cost of the
EPROM. When Logan wasn't
wearing his "Rainbow hair"(a
multi-hued wig), he was busy
showing off his CoCo/ PC. The
CoCo/ PC is a CoCo 2 with two
slimline drives, disk controller
and CoCo Max all packed into
an IBM PC case. To power the
system, Logan wired in a 130-
watl IBM power supply. The
system has also been modified
to use switchable composite
video as well as an inboard
audio amp and lap keyboard.
RAINBOW and Delphi regular Martin H. Goodman, M.D., "operates" on
a CoCo 3.
While several onlookers
watched with great interest,
Marty Goodman dissected Art
Flexser's newly purchased
CoCo 3. The reason for the
operation was to install a socket
for the ROM chip internal to
the CoCo 3. Art seemed to be
pacing the floor, much as an
expectant father would, as
Marty carefully explained each
step of the procedure. The op-
eration was a success and Art
became one of the first people
to own a CoCo 3 with a sock-
eted ROM chip.

GRAPHICS
Generate a graphic printout directory
of your picture disks
By Chris W. Brown
While amazingly efficient, those
eight-character filenames
leave a lot to be desired when
it comes to graphic images. This is
especially true if you are as lazy as I am
and file seven progressive images of a
dogwood blossom as Dl, D2, D3, etc. I
used to find myself loading in a program
to scan each picture on a disk, then,
once I found the image I wanted, load-
ing in another program to use that
picture. Those days are over. Now I
have GRADlR, which is my six-letter
abbreviation for "Graphic Graphics
Directory Image Processor and Filer
Program."
gradir is a basic program that can
take a disk full of graphics images (up
to 22 PMQDE 4 screens, each 6,143 bytes
Chris Brown lives in Siloam Springs,
Ark., and has been a professional artist
for 20 years. A Co Co enthusiast for five
years, he has used his computer for
everything from managing rental prop-
erty to designing special logos and
fonts. His computer art is distributed by
Grafx.
long) and produce, on one screen, a
complete graphic directory of all the
images on the disk. In a very reduced
rendition, every picture stored on a disk
is shown, complete with its filename, on
one PMODE 4 screen. As small as the
images are, they are still easily recogniz-
able. A photographer might compare
one of gradir's screens to a contact
print of a roll of 35 mm film. It's very
handy for selecting images and filing.
This program is simple to use. Load
GRADIR, then PCLEAR8 before you run.
The program uses the first four PM0DE4
pages for loading graphics from disk
and the last four pages for assembling
the directory.
First, you are greeted with a request
to stand by while the program initiates.
The standby lasts only a couple of sec-
onds while the alphanumeric and "long
file" arrays are set up. During initiation,
the grid for the directory screen is also
set up. It's sometimes amazing how
many things our CoCo can accomplish
in a short time. After set up, you are
asked for an eight-character filename
(the program won't take a longer one).
This is the name of the disk you are
cataloging and will be used to label and
save the graphics directory created by
the program.
Then you are asked for a date (any
format), which will also be used to label
the finished directory. After you have
entered the date, the program prompts
you to put the disk to be cataloged in
Drive and press ENTER.
Now you can sit back and watch the
computer do its work, or go do some-
thing else. The processing of each
graphics image takes about one minute.
If you have a disk full of single-screen
images (22 is the maximum number you
can have on one side of a standard disk),
it will take about 22 minute's to create
the Graphic Graphics Directory for that
disk. When the last image on the picture
disk is complete, the computer displays
the complete directory on the screen
and makes a pleasant beeping until you
press any key.
Now comes the rest of your labor:
swapping disks. You are prompted to
put a directory disk in Drive 0. I have
a lot of graphics on disk and I've found
that I prefer to segregate these graphic
directories onto disks by themselves.
There would be no harm in saving the
directory on the disk cataloged, pro-
88
THE RAINBOW February 1987
vided enough free space is available. If
there isn't, the program will warn you.
In fact, it won't allow you to try to save
the disk directory at all on a disk with
less than three free grans, thanks to Line
700.
A note about the quality of the small
images before we take a walk through
the program's functions: It doesn't
matter in which PMODE the image was
created. GRADIR uses PMODE 4 to allow
the capture of the most detail. PMODE
through PMODE 3 screens require the
same amount of time to process, but
appear scrunched up (PMODE -
PM0DE2) or not in color (PMODE 3). You
won't, except in very rare instances, see
the glorious colors of your original in
the small directory version. Remember,
the small directory version is a "proof
copy" only.
Now to the workings of the program.
A quick glance at the list of routines
(Figure 2) and the program (Listing I)
shows a pretty straightforward ap-
proach, with the subroutines located at
the beginning of the program for speed.
The first subroutine (lines 30-100)
draws the Hi-Res characters on the
PM0DE4 Hi-Res screen. This subroutine
requires five variables: color, l<2 (0-8);
size, 52 (1-63); X position, PW (0-255);
Y position (PQ (0-192); and words, NS.
The Check File Length subroutine is
a bit more esoteric. Grabbing one
record at a time from the disk file, this
routine calculates the start and end
addresses from the MSB and LSB
(most-significant and least-significant
bytes) information contained in records
1 and 2, 3 and 4, 6, 8 and 9. The result,
the length of the file in bytes, is stored
in the variable LONG, which is used later
in the program.
Line 1 80 contains the heading for the
text screen. Revise this as you will. The
pokes to the screen only put black
spaces after my first and last names.
Line 200 sets up the array GP which
positions each of the 22 possible small
images in a discrete position on the
screen. Reading the numbers in the
DATA statement in pairs gives youtX, Y
coordinates. These coordinates, as
determined by the processed picture
number (CN), are used in Line 580.
Lines 210 to 300 set the array LS(1)
to LS ( 59 ) . This array contains the DRAW
instructions used by the Draw Letters
subroutine. This, plus the drawing
routine, 1 keep as an ASCII file on one
of my many utility disks, merging it
when I need alphanumerics on a graph-
ics screen. This particular version is

special for GRADIR because the letters
had to be small. Different versions of
this approach have been seen here in
THE RAINBOW.
The heart of the program is in lines
390 to 460, the original of which is in
the Disk BASIC Manual from Radio
Shack. Of special note is Line 40, which
rejects any file whose extension is not
PIC. If your graphics are not filed as PIC
but rather as PIX, the solution is simple.
Make Line 410 read PIX. However, if
you commonly use the extension BIN
for your graphics screens, a real prob-
lem exists. If you substitute BIN for PIC
in Line 410. the program will try to load
any and all BIN extension files, which,
if the file is not a graphic, could cause
the computer to go nuts and lock up.
My suggestion is to rename your graph-

ics, using either PIC or PIX for the
extension.
Lines 510 to 600 comprise the image
processor. The routine loads each 6,143-
byte-long image on the disk in turn,
then processes it by taking every sixth
byte on every sixth line and composing
a picture in the upper left-hand corner
of the screen. You may notice that the
creation of the small image, because of
the STEP G, allows a dual use of the first
screen. This small image is transferred
with the GET and PUT in Line 580 from
PM0DE4 Screen One (pages 1-4) to
Screen Two (PM0DE4 pages 5-8) and
labeled with the Draw Letters subrou-
tine in the wink of an eye.
Lines 490 and 540 enable this pro-
gram to avoid graphics files longer than
the single PM0DE 4 screen, such as the
eight-page saves made with Derringer's
Master Design or Colorware's CoCo
Max. If the whole eight-page file were
to be loaded, it would destroy the
directory being created on PMODE 4
pages 5-8. To keep this from happening,
the place marker created by Line 310 is
used, with the proper filename, instead
of a reduced image.
After the directory is completed, it is
copied from pages 5-8 to pages 1-4 by
Line 630. The disk filename you entered
earlier, the date and the free grans on
the picture disk are written to the
directory screen and then the beeping
begins in Line 680.
Pressing N when the program asks if
you want to save the directory allows
you the option of entering a new disk
filename for the directory. If, at this
point, you want to start over, simply
press ENTER, which sends you to the
end-of-program menu. Pressing Y at the
SAVE prompt sends the program execu-
tion to Line 730.
Line 730 is a standard four-page
graphics save. Line 740 starts the end-
of-program menu. This menu gives you
three choices: restart, end or menu.
Restart runs the program from scratch.
This is what you choose when you are
ready to catalog your next graphics
disk. End stops the program and returns
you to BASIC. Menu is a convenience I
added for myself. I have several graph-
ics design program disks. All of them
are menu driven, and the menu program
on each disk is named MENU.BAS. A
switch of the disks, two key presses and
I'm three programs away. The lazy
artist's graphic system.
Having cataloged all of your graphic
disks, run each of the directories
through a screen dump utility. Using the
hard copy produced, you have a com-
pact, concise and impressive catalog of
all your graphics efforts, a computer
artist's portfolio.
I will be glad to answer any questions
about this program. My address is P.O.

Customizing Color
While disassembling Extended BASIC on the CoCo
3, 1 found that the PALETTE CMP default values occupy
memory locations from SE654 to SE663. Default
values for PALETTE RGB are in locations SE664 to
SE673 and the present PALETTE values are in locations
SE678 to SE687. You can customize two color sets by
poking respective values in the PALETTE CMP and
PALETTE RGB ranges and then switching between them
with one command. You can then peek the present
PALETTE values to find out what color is in what slot.

If you use your spreadsheet program to keep track of youi
expenses then @ SUMMARY can help you analyze those
expenses. For example, if you indicate a "Category" lor each
expenseljien @ SUMMARY will produce a report that shows
a total for each category, the highest amount, the lowest
amount and the average amount. In addition, ©SUMMARY
can produce a hi-res line graph or bar graph of the analysis
and allow you to place titles on the graph. A hardcopy of the
graph can also be generated as well as saved to disk.
The analysis can be saved in a "data file" which can be
loaded into DYNACALC or read in by @ SUMMARY for future
additions to the analysis. If you use other Spreadsheets such
as EUTE'CALC then you have added a graphing feature to
your spreadsheet applications. The analysis can also be saveo
in an ASCII file which can be read by word processors lot

DISK UTILITY
A handy disk utility for the CoCo 3
Take Command of
CoCo 3 Drives
By Michael N. Jorgenson
I have a vast assortment of utilities for the older CoCos,
but only a few of them will run on the new CoCo 3.
So, I have written my own utility.
DU-3 is a disk utility written in BASIC, and it contains many
interesting features. The operating commands are Copy,
Drive. Kill, Load, Name, Scan, Quit and Verify. An INKEYS
control letter is given for each command.
Upon start-up, the directory of a disk in Drive is read
and displayed in split format on the 40-column text screen
in numerical order with extensions and granule allocations.
The free granule space of the disk, if any, will also be shown.
The BREAK key can be used to escape any function, or
to read in another disk on the same working drive. Pressing
C copies any or all files from one disk to another. The
program prompts for the destination drive number (the
default is Drive 0). A single-drive copy can be made on any
working drive. Use the D key to change your working drive.
Press D and the number of the drive you want to use (0
to 3); the default is 0. Pressing K kills any or all files on
the working drive disk.
To load any file on the working drive disk, press L. Use
N to rename any file on the working disk drive, including
the extension. S scans the working drive disk; the program
prompts for a starting track and sector. Use Q to exit, and
use V to toggle Verify on and off.
Michael Jorgenson is an electronics technician and a novice
programmer. He lives in Lorain, Ohio, and enjoys working
with Disk BASIC, games, utilities and telecommunications.
He is also a published author of several short Fantasy j
Adventure articles and games.
DU-3 only works on the Color Computer 3. It does not
use a speed-up poke, but it will execute a PCLEAR1. This
is to minimize disk-swapping on single-drive systems. The
"Insert Destination Disk" prompt that appears on single-
drive copies is in Disk BASIC, which looks a bit crummy on
the 40-column screen. I could not find a way to work around
it.
DU-3 reads and displays up to 68 files. If there are more
than 36 files, the display scrolls upward off the screen, but
does not affect program operation.
(Questions about this program may be directed to the
author at 749 Tower Blvd., Lorain, OH 44052, 2/6-282-
9355. Please enclose an SASE for a reply when writing.)

Creating a Review Program
By Joseph Kolar
Rainbow Contributing Editor
The beginner who has stayed the
course and faithfully struggled
through these "Basic Training"
tutorials, has reached the point where,
after a review, he can consider himself
a veteran.
Today, the project is to create a
review program. A sentence in one
language is displayed on the screen. A
second, translating-language sentence
with a randomly selected, blanked-out
word/ phrase is displayed below. With-
out any hints (except comparison with
the first language) he is required to take
a guess as to the missing word/ phrase
that would make the sentence whole.
When he presses any key, the answer
will be filled in. At this point, you may
want to set aside this issue of THE
RAINBOW, take up the challenge and see
what you can come up with. If you have
been studying these inspiring, fun-filled
tutorials for the past year, you have the
background to make a creditable pro-
gram.
Key in lines to 6, 20, 21, 23, 24 and
995 from Listing I. We will use Line 20
for the first language and Line 2 1 for the
translating language. Line 1 gives the
starting locations on the text screen. It
also chooses a random color, other than
black or cyan, and having chosen a
color, proceeds to Line 10. Line 10
clears the screen and is directed to a

of the Color Computer.
selected line number of a portion of the
program that is currently being devel-
oped. CoCo stores (memorizes) the two
strings, X$ and Y$ in lines 20 and 21,
respectively, and awaits our pleasure.
Temporarily, insert P=31:Q=P:
G0SUB3:EXEC44539 as Line 22. P and
are the variables that give the approx-
imate number of characters/ spaces in
strings X$ and Y$, respectively. CoCo is
told to go to Line 3, follow the instruc-
tions and return.
Line 3 tells CoCo to print, beginning
at X, P number of character/ spaces,
starting from the left side of siring XS,
and to abort any trailing blank spaces
at the end of the last row. Ditto for the
second string. CoCo returns to Line 22
and waits for any key to be pressed. Run
your work.
This is a good time to check spelling,
punctuation and formatting. In fact,
you will want to create Line 2000:
P=181 : Q=P : GDSUB3 : EXEC44539 : RETURN
and change Line 22 to GOSUB2000. Now
run.
In the second translating language we
want to blank out THE CITY. List Line
21. Directly from the screen, we count
to the numerical value that starts the
blank-out area and assigns it the vari-
able A. (Remember, is the upper left-
hand location.)
Count the number of spaces to be
blanked out. The first space after the
starting quote is number 1. Count up to
and include the space after the last letter
to be blanked out. Assign the total a
variable, N=ll. This system gives you a
little leeway. For instance, in Line 23,
your calculations can be pretty casual
and imprecise. If fl=0 then N=10 or
N=ll; if A=l then N=9 or N=10; if 0=2
then N=8 or N=9. All these pairs will
work equally well.
Delete Line 22. Line 23 provides both
the A and N information that CoCo
demands before it can zoom over to
Line 5 and work its tail off.
List lines 3 through 5. Allowing for
extra-long, multiple-row sentences,
CoCo trots up to Line 3 and prints both
strings, XS and YS, in their entirety.
Then it jumps back to Line 5. Beginning
at Y, plus any offset (P.), it will print a
row of CHRS(143) (the same color as
the screen background), for a total of N
spaces. At this point, it returns to Line
24 and waits for you-know-what!
CoCo shoots over to Line 4, where
the translation line is reprinted in place
and restored to a complete sentence.
CoCo waits for a key to be pressed,
whereupon it clears the screen, chooses
a random color, and returns to be
directed to the next pair of sentences.
Run this.
For the heck of it, edit Line 5 so 143
becomes 12B, and run. That doesn't
look too bad. If you prefer a black
blank-out, your A value should begin at
the location of the first letter to be
hidden, and N should include from the
first letter through the last letter of the
blanked-out word/ phrase. In this case,
A=2:N=B.
For the nonce, edit Line 5 so 128 is
143 and make sure R=0:N=11 in Line
21. Run to make sure.
List lines 20 to 2 1 . It doesn't take long
February 1987 THE RAINBOW 101
to note that we could blank out other
areas.
Insert GDTD 25 as Line 22. Key in lines
25 and 26. Insert Line 40 as a remark
statement, to hold the spot open for the
next pair of sentences and to avoid the
UL Error we were getting. Now run.
In Line 25, all we needed to do was
select new A and N values. Line 26 is
identical to Line 24. This time BIG was
washed out. Change 25 to 27 in Line 22.
Key in lines 27 and 28. Run and see OLD
vanish. Again, the lines were similar,
except for new A and N values.
Change 27 to 29 in Line 22. Key in
lines 29 and 30. You can see, AND got the
treatment this time. Run. Sure 'nuff!
Notice that since the next line will be
Line 40, I did not put -.GOTO40 at the
end of Line 30. But, as a beginner, you
should use it and CoCo won't holler.
CSAVE "PARTI".
Best laid plans often go awry. While
1 was mulling over what we had
wrought, it struck me that we were
asking CoCo to do something in an
oblique way, for which CoCo has a
perfectly good function, MIDS. Do you
recall, veterans of past bouts with MID$,
that it was pointed out that there were
both a MIDS statement, which we used
to good advantage, and a MIDS func-
tion, which I glossed over ever so
quickly?
Without being aware of it, I proved
the old adage, "There is always more
than one way to do anything." If you
crack open your ECB manual, you will
note that MID$(X$,A,N) equals re-
placement, where X$ is the string, A the
position of first character to be blanked
out and N is equal to the number of
characters to be wiped out. Doesn't that
sound familiar?
Consider: X$, A and N prepare to do
exactly what we want to occur and yes,
we have a replacement, STRINGS
(N,143). Look Ma, no MIDS function!
You are invited to try your hand at
working out a small program to dupli-
cate what our tutorial does, up to this
point. Hint: Use lines 1, 10, 20, 21, 40
and 995. Use PARTI advisedly. In the
next tutorial, you will be given one
answer plus some insights on how it was
constructed. In the meantime, let us
continue. We have four different areas
blanked out. Rather than get bored stiff
displaying all four variants, wouldn't it
be better if we picked one at random,
displayed it and moved on to the next
pair?
Key in Line 22 and run it a few times.
We shall begin the next set of sentences
starting at the reserved Line 40. Key in
Lines 40, 41 and 43. Change Line 10
from 20 to 40, type 42 GOSUB2000 and
reserve Line 60 (S0'). Run this and
check it out.
This time we are consolidating the
two-line format (as in lines 23 and 24)
and turning it into a one-liner. Insert
Line 42: GQTD45. Key in Line 45 and
run.
shall reverse the languages to get
another perspective. Here, again, are
the steps in creating this routine.
Change G0 to 80 in Line 10. Key in lines
80, 81 and 83. Reserve Line 100 (100').
Key in 82 GOSUB2000 and run.
Re-key B2 G0T0B5. Key in Line 85
and run.
Re-key B2GDTDB7. Key in Line 87.
Run until all the variations check out.
'Without being aware
of it, I proved the old
adage, 'There is always
more than one way to
do anything. 999
Change Line 42 to read GOTO 47 and
key in Line 47. Now run. You can drop
the :GOTOG0 from Line 47, if you like.
We are only making three variants.
Key in Line 42 from the listing and run
a few times. In Line 10, change 40 back
to 20 and run.
Notice that we work methodically,
checking each line as we add them. It
is no sweat to isolate and correct a newly
created mistake. Hasty, unverified work
only guarantees a difficult debugging
session later.
In Line 10, change 20 to G0. Key in
Lines 60 and 6 1 . Reserve Line 80 (B0 ' ).
Insert Line 62: GOSUB2000. Now run.
Check the format, spelling and punc-
tuation.
Key in lines 63 and 65 and run. Re-
key Line 62, G0TDG5 and run. At this
stage, we note that an integral part of
our program is the sequence GO
SUB5:EXEC44539:G0SUB4. This is a
pain to key in frequently. How can we
shorten this repetitious task? Key in
Line 6. Sure! Create a GDSUB out of the
sequence! Key in Line 67. Change Line
62 to G0T0G7 and run. This is good!
We could go back and change lines 23
through 30, 43 through 47 and 63
through 65 to reflect this modification.
It doesn't really matter. Long form or
short form, both accomplish the mis-
sion equally well. From now on, we
shall use the condensed form.
Re-key Line 62 from the listing and
run. In the next pair of sentences, we
We switched languages to see if this
pairing was better than the original
presentation. Why do we do the obvious
and check what we know will work? We
try every variation we can think of. This
repeated toying with the program may
turn up a dormant bug. It may also give
us other ideas to pursue. You never
know what you will think up while
doing monotonous tasks. Using the
previous procedure, work out the next
pair of sentences from lines 100 through
107.
You have become aware of how un-
taxing it is to create this program. A
pair of sentences is chosen, portrayed
and checked out on the screen; various
blank-outs are decided upon; A and N
values are determined; and so forth.
The line-numbering is consistent
throughout. In the random-selection
lines, the ON line is easy to construct.
Looking at it another way, using L=20
to indicate the program line number we
have:
L XS
L+l Y$
L+2 (temporary line pointers)
L+2 M=RND(x):DN M GOTO L+3,
L+5, L+7, etc.
L+3 variant 1
L+5 variant 2
L+7 variant 3
L+20 next XS
102
THE RAINBOW February 1987
We increment each L by +20 to allow
for many variants in long sentences. The
case is made to show that a simple,
consistent procedure is lots of fun to use
and results in rapid progress.
Thus far, we have been fooling
around with the second language. Who
knows when we will have an occasion
to blank out a portion of the first
language? Let us prepare a routine to
add to the armaments in our arsenal of
GOSUB routines.
To consult our program, list the first
10 lines and note that Line 5 did the
blank-outs on Y$. A similar line with
one judicious change should do the
trick. Key in lines 7 and 123 from the
listing. Change 8 to 7 in Line 123 and
run. No Good! We get a flickering XS.
That means it is probably OK, but
CoCo, not given a warning to wait for
a key press, flickers through it and goes
on to repeat.
List lines 5 through 7. We see in Line
6 that after G0SUB5, which did the
blanking, we had the pause that re-
freshes (EXEC44539). Although an easy
alternate way may come to mind, we
shall be true to our system and key in
Line 8. Change 7 to B in Line 123. Can
you think of the other way that seems
obvious? Run this.
CoCo displayed both sentences,
blanked out and then restored the word
in VS. and then blanked out and re-
stored the definition in X$.
Remember, we are experimenting!
Re-key 122 G0T0125. Key in Line 125
and run.
This time, we add A and N values to
display blank-outs and restorations in
both Y$ and X$. In Line 125, delete the
second fl = 6: and run. CoCo picked up
the last fl value and ran with it.
List lines 120 through 123. You can
see why no new fl and N values were
given for G05UB8 to work with. In lines
120 and 121, FIRST and ERSTE both
begin at A=6 and are N=6 spaces long.
Change 125 to 127 in Line 122. Key
in Line 127. Note the abbreviated Line
127. Again, we do not require a second
set of fl and N values, and the GOTO140
was not used because it's redundant.
Still experimenting, we try out a pair
of sentences that require more than one
row to display. You know the plan of
attack. Check out this last routine on
your own.
After you finish this task, we meditate
a while and think: We have chosen one
variant at random from each pair of
sentences and displayed it. Then we
chose and displayed a random variant
from the next pair, going through all the
sentences. Line 995 returns to recycle.
Instead of always beginning at the
first pair at Line 20, why couldn't we
drop down at random and begin at any
selected pair? Re-key 10 CLSZ. Key in
Line 1 1 and run.
It works, but we never change back-
ground colors. Change 10 to 1 in Line
995 to go to the line that chooses a new
color. We get a hint every time a new
color is portrayed that we ran through
a complete set and a new one is being
announced.
To make X$ in the last two pairs end
up restored, change B to 9 in lines 143
through 149. Key in Line 9 and run.
If we don't want the last pair of
sentences in our program, we can alter
Line 1 1 to omit them. Change 7 to S
and, if you are a perfectionist, delete
,140. Now run.
You could end by keying in lines 990
and 999, both unmasked, and masking
Line 995. Run and CSflVE"PR0
GRAM". But, that is not truly random.

February 1987 THE RAINBOW 103
Unless the last pair at lines 140 and 141
are chosen, CoCo proceeds sequen-
tially, from its beginning, ON M, chosen
in Line 1 1. To avoid the predictability
of repeating a sequence of sentences, try
this:
Make sure Line 10 reads CLSZ.
Change all the various GOTQs to GOTO
1 in the following lines: 24, 26, 28; 43
through 47; 63 through 67; 83 through
87; 103 through 107; 123 and 125. Add
:G0T01 at the end of lines 30 and 127
and run.
That is the end of the review session.
I hope you enjoyed plodding through
the listing, and used some of the tricks
you studied in the past. This program
demonstrates how we make CoCo bend
to our will — willingly! □

Create fast, detailed Adventure game graphics
Instant Graphics and
Hogs in Space
By Courtney Powers
-1
There have been two main types of
Adventure games seen so far in
these pages: text Adventures and
those combining graphics and text. Text
Adventures do not satisfy because they
lack what our favorite computer is so
famous for — color. An Adventure
game with mixed text and graphics that
draws the characters on the graphics
screen is the best solution.
Doing this in BASIC, however, leaves
us with the pictures drawn slowly in
front of us or slowly on a graphics page
not currently being viewed, leading to
long, unexplained delays in the execu-
tion of the program. A method I have
seldom seen used is the simple expedient
of drawing the pictures ahead of time
and saving the graphics pages to disk as
machine language programs.
The instruction for saving a machine
language program, SflVEM. requires
four items of information: a filename,
and the start, end and transfer ad-
dresses.
Where is the start of the graphics
screen memory? The Color Computer
stores the number of 256-byte bounda-
ries to the beginning of the graphics
pages in memory location Hex BC.
Therefore, S=PEEK(&HBC)*25G gives

us the address we are after. The variable
5 now contains the location in memory
of the upper-left corner of the screen in
Graphics Page One.
Next, we need to know the end ad-
dress. Again, this is quite simple. The
graphics page takes up 6K of memory.
To find its end address, use E = S+
( 1024*G ) -1. Why the -1 in the assign-
ment? You are starting to count at zero
here. S+6K is one memory address past
the end of the screen.
Now we have a method for getting the
entire screen saved to disk. What? I
forgot the transfer address? Well, we
don't want to execute this particular
program, as graphics bytes don't make
good ML instructions, so we'll just
cause this particular "program" to
execute Color BASIC. Thus, our transfer
address is T=&HA000, which is the
beginning of our BASIC ROM. To
save our picture we merely write
5A VEfl "filename" , S , E , T.
Most of the Adventures we have seen
so far do not use the entire screen for
graphics, however. The top of the screen
is customarily used for graphics and the
bottom for the drawn-in text. So we
only need to save the top half of the
screen where we draw our pictures.
Instead of 6K past the start address, we
only go 3K. Here is our modified rou-
tine to save the pictures:
1000 S=PEEK(&HBC)*25G
1010 SflVEM "filename", 5,3
+1024*3-1, S.HA000

February 1987 THE RAINBOW 107
To get the picture back from disk and
onscreen, we merely load the ML pro-
gram. Type LOf\D^"f ilename" .
In the demo program, I wanted a
color similarity to Sands of Egypt (blue,
orange, black and white), so I could
have black space and white stars. How-
ever, this color combination is not
available in PMODE 3.
The demo program, H0G.BA5, draws
the pictures in PMODE 3 and displays
them in PMODE A. Since both modes
require the same amount of memory, it
is possible to locate the picture in the
same memory addresses in both modes
and get the color combinations 1 like.
The interesting things that happen to
colors when you save a picture in PMODE
3 and reload them in PMDDE A are
gratifying. You can now have four
colors in PMODE A without actually
going to the trouble of poking each
pixel into place!
The manner in which the graphics
screen changes will be familiar. You can
make your source picture as compli-
cated as you want, and it loads in at the
same speed each time — much faster
than drawing in real-time.
Another thing we need for a graph-
ics/text mix is a good routine for
drawing the letters on the screen. The
routine in the demo program does this
nicely and can be merged into any
program. Use RENUM and MERGE wher-
ever you like, but the routine does work
slightly faster if it is put at the beginning
of a program.
To use HOG.BAS, first load the pro-
gram. Then put a formatted, blank disk
into the assigned drive. Run the pro-
gram. You are first quizzed as to the
color appearing on the screen. For some
unknown reason, the CoCo randomly
interchanges the two added colors in
PMODE A each time the computer is
turned on and off. Therefore, we have
108

to redraw the scenes for each new
session.
Once we have ascertained the correct
coloring, the computer goes to work
drawing the scenes for the game. This
is a good time to go to the kitchen for
a cup of coffee. To draw all the scenes
takes a couple of minutes. A beep
informs you when it is done with this
task, and you are asked whether you
need to go through the instructions or
not. 1 always do, as 1 find them almost
as much fun as the game.
After you have received your instruc-
tions, it is a simple "Hunt the Wumpus"
type of game with a numbered search
grid and inputting coordinates such as
1.2 or 6.6 to go to those places on the
grid. A game like this is really much
better with graphics, as you can visual-
ize where you are and what you are
doing there.
In the demo program, HOG.BAS, I
have merged the drawing routine into
the game program. You could have the
drawing routine in a separate program,
but this way the blue/ orange colors
come out correctl y each time. However,
if you are like me and
like to chance it, once
you have run the pro-
gram one time and
have the pictures on
disk then you can
avoid the delay of
picture drawing. Just
type RUN 3000 and
start playing. If you
are lucky, the blue/
orange colors will
come out right. If
not, you must either
run the program,
press RESET and
enter RUN 3000
again, or live with it.
The subroutine
that draws the letters
on the screen is in
lines 40 to 520. This
subroutine can be
isolated and merged
into other programs.
To use it, assign loca-
tion coordinates LX
(0-255) and LY (0-
191), put the message
to be printed in AS,
and call the routine.
At Line 1 we im-
mediately jump to
Line 630 to get past
our character-draw-
ing routine, and start
by making sure our
disk drive is pre-
pared. Then we check our color in lines
730 to 770 and assign the color variables
C2 and C3. This is essentially the me-
thod I have seen Fred Scerbo use in his
"Wishing Well" articles. Then, at Line
830 we start drawing our pictures and
saving each one to disk as a machine
language program.
At Line 3000, our pictures drawn, we
ask the player whether he wants to go
through the instruction sequence. If the
player chooses immediate play, we
branch to Line 4000 and the start of the
game. If not, we go through an instruc-
tion sequence that consists of just
loading in the pictures and showing the
instructions. From Line 4030 to Line
4370 we prepare the game by setting up
initial conditions.
Starting at Line 5030 (the top of the
main loop) we draw in the picture
appropriate to our current location,
draw a "gravitonic detector," and fill in
blocks to show nearby objects. At lines
5380 and 5390 we check to see if the
player has won or lost the game. Then
at Line 5430 we get the player's move,
and go back to the top of the main loop
at Line 5670.
The routine that prints a message
appropriate to each location is in lines
6010 through 6130. The "win game"
routine is in lines 6170 to 6280, and the
"lose game" routine is in lines 7030 to
7140. The infamous INKEY subroutine
is in Line 19999, ending our program.
The main purpose of all this is to
provide you with the tools to construct
an Adventure game that gives you a
professional-looking picture change,
and to get rid of all those awful text
Adventures. Put in some graphics that
make us proud. Let the games begin!

WE'RE BRINGING THE COCO
RAINBOW'S
BROADENING ITS
SPECTRUM
the rainbow and the Delphi Infor-
mation Utility have joined together
to allow CoCo owners all over the
world to connect with one another!
Delphi is a full-service information
utility. It offers everything from up-
to-the-minute news stories from The
Associated Press to electronic mail
services. But, best of all, it now has
a special forum for Color Computer
owners, and it's operated by the
people who bring you the rainbow
each month.
The CoCo Special Interest Group
(SIG) features a variety of services,
including an open forum where you
can send and receive messages
from Color Computer owners all
over the world. It also has several
databases to which you can upload
your favorite programs and from
which you can download programs
written by other CoCo enthusiasts.
Some of these databases are basic
programming, OS-9 and home ap-
plications.
When setting up your account with
Delphi, if you do not have a credit
card or prefer not to use it, Delphi
requires that you send $20 to give
your account a positive balance. This
will be refunded after your first free
hour if you choose to no longer use
the system or it will be applied to
future connect charges. If you do not
maintain a positive balance, you will
be charged $3.50 each month for
direct billing.
PEEK INTO THE
RAINBOW
The CoCo SIG's conference feature
allows you to meet electronically
with other members of the CoCo
Community. You can join conferen-
ces with notables such as Dale
Puckett, Cray Augsburg, Marty
Goodman, Don Hutchison, Jim
Reed, Lonnie Falk and others —
on a regular basis. Conference
schedules will appear in the rain-
bow each month. Be sure to check
online announcements for changes
and additions.
THE OTHER SIDE
OF THE RAINBOW
On Delphi, you also are able to buy
rainbow on tape — order a whole
set, or download an individual pro-
gram immediately. You can also
renew your rainbow subscription,
make a fast and easy order for soft-
ware or hardware from a multitude
of vendors, or inquire about prod-
ucts on the CoCo SIG.
We also have a number of programs
that you can download and use, just
for the cost of the time you spend
transferring them. There'll also be
corrections for rainbow articles,
helpful hints and many other useful
features.

How to reach RAINBOW'S Color Computer SIG . . .
There are several ways to connect to Delphi and THE
rainbow's CoCo SIG. In most cities you will not even have
to pay long distance charges; you can use special data
communications networks like Telenet, Tymnet and the
Canadian Datapac network.
First, set your terminal program to operate at either 300
or 1200 Baud (depending on the modem you have), and
also select either 7 bits with even parity or 8 bits with no
parity, and one stop bit. (If one combination doesn't work,
try another.)
Decide which network you should use. There is no
surcharge for Telenet or Tymnet. Canadian residents using
Datapac will be charged an additional $ 1 2 (U.S.) per hour.
On Telenet: The Uninet network has now merged with
Telenet. To get the Telenet number for your area, call (800)
336-0437. After you call your local access number and
make connection, press the ENTER key twice. When the
"TERMINAL^" prompt appears, press ENTER again.
When the "@" prompt appears, type C DELPHI and press
ENTER.
On Tymnet: Call (800) 336-0149 to get the Tymnet
number for your area. After you dial your designated
number and connect, you will see either "garbage" or a
message saying "please type your terminal identifier." At
this point, even if the screen is garbled, simply press 'A'.
When "please log in:" appears, type DELPHI and press
ENTER.
From Canada (on Datapac): Call Delphi Customer
Service at (617) 491-3393 to get the Datapac number for
your area. After you connect, press the period key (.) and
ENTER (use two periods if you're using 1200 Baud). Type
SET 2:1, 3:12G and press ENTER. Now type p 1 3106,
DELPHI; and press enter. Delphi's new rates indicate an
additional $12 hourly surcharge for evening use of
Datapac, which means a total of $18 (U.S.) for connect
time.
From other countries: Many countries have their own
data networks that can connect to cither Telenet or
Tymnet. Check with the telephone authorities in your
country for details on how to sign up for this service. When
you have an account set up, you can reach Delphi with
a "host code" of 312561703088 through Telenet, or
3 10600601500 through Tymnet. (You'll have to pay the toll
charges for this connection.)
Type in Your Username
If you're already a subscriber to the rainbow, at the
"USERNAME:" prompt, type RRINB0W5UB and press
enter. At the "PASSWORD:" prompt, type your individ-
ual subscription number from the mailing label of your
latest issue of the rainbow. (If there are one or more zeros
at the beginning of this number, include them.)
If you don't already have a subscription, at the "USER-
NAME:" prompt, type RfllNBOWORDER and press ENTER.
At the "PASSWORD:" prompt, type SENDSUB and press
ENTER. Have your MasterCard, VISA or American
Express card ready, because you'll be led through a series
of questions that will enable us to put your rainbow and
Delphi subscriptions into effect. In an effort to hold down
non-editorial costs, we do not bill for subscriptions.
If you make a typing error, just press ENTER and start
over. Remember that at any point, when you're on Delphi,
you can type HELP to get help on how to use the system.
To get off the system just type BYE.
If you find that you're unable to log on to Delphi and
enter the CoCo SIG after following these instructions, call
us during afternoon business hours at (502) 228-4492. We'll
be glad to offer assistance.
Come Visit Us! Type: GROUP CDCD
After you sign in, you'll be prompted to set up your own,
personal "user name" — Delphi is a friendly service, no
numbers to remember — and you'll be asked a number
of questions so Delphi can set up your account. You'll also
be assigned a temporary password. No time is assessed
against your free hour of service while you answer these
questions.
Delphi will tell you that your account will be ready after
6 p.m. the same day if you sign up before noon (Eastern
time zone.) If not, your account will be ready at 6 p.m.
the next day. Once an account is opened, each rainbow
subscriber will be credited with an hour of free time!
When you log back in, use your chosen username and
your temporary password to access the system. At that
point, you will meet Max, who will help you configure
things and will change your temporary password into
your own personal password. This is the password you
will use for subsequent sessions — or until you change it.
After Max bids you goodbye, you'll wind up at the
Delphi Main Menu; type in GROUP CDCO and join us on
the CoCo SIG!

The new Color Computer owner buys his/her versatile
machine for its graphics and music capabilities, organization
of their home and office, educational purposes — both in the
home and school and to acquire programming knowledge — and
some, simply for pure fun and entertainment.
As far as the CoCo is concerned, the more you learn, the more
you realize how little you actually know. That is why every session
at the keyboard is an adventure in learning.
THE RAIN BOW is a teaching environment and we realize that
the majority of our readers will always be beginners. In our
continuing effort to always keep the new user in mind and in
addition to the many beginner feature articles and programs
published in every issue, "Novices Niche" will contain shorter
BASIC program listings that will entertain and help the new user
un^nd
gain expertise in all aspects of the Color Computer: graphics, music,
games, utilities, education, programming, etc.
Contributions to "Novices Niche" are welcome from everyone.
We like to run a variety of short programs that can be typed in at
one sitting and will be useful, educational and fun. Keep in mind,
although the short programs are limited in scope, many novice
programmers find it enjoyable and quite educational to improve the
software written by others.
Program submissions must he on tape or disk. We're sorry, but
we do not have the time to key in program listings. All programs
should be supported by some editorial commentary, explaining how
the program works. If your submission is accepted for publication,
the payment rate will be established and agreed upon prior to
publication.

Hand Offis a simple, but challenging game. The object is
to pass a ball from one block to another as the blocks move
vertically in opposite directions across the screen. The ball
starts in the block in the top row and the block moves rapidly
across the screen in one direction while the block in the row
underneath moves across the screen in the other direction.
To pass a ball down, press any key at the exact moment
the blocks meet. To accomplish a win, the ball must be passed
all the way to the block at the bottom. The faster the ball
is moved to the bottom, the better the score.

Next to your computer,
nothing beats a Tandy printer.
Tandy printers make fine print quality,
graphics and high performance affordable.
A match for your machine
For your best value and selection in
top-quality printers, shop your local
Radio Shack Computer Center. We've
got the printer that you need.
Dot-matrix power for business
The DMP 2200 (26-1279, $1695.00)
gives you efficient, fast printing at 380
cps. It supports elongated, double
high, bold, underline, super/subscripts,
italics and double strike, plus bit-
image graphics.
The DMP 2110 (26-2810, $1295.00)
prints at 240 cps. Use the Font Editing
Packages (sold separately) to load dif-
ferent type styles for print quality that
rivals a daisy-wheel printer!
The DMP 430 (26-1277, $899) is a
132-column dot-matrix printer that
delivers superior correspondence char-
acters. Plus, in the draft mode, the DMP
430 delivers a fast 180 cps.
Low-cost, triple-mode
personal printer
The DMP 130 (26-1280, $349.95)
lets you choose from word processing,
data processing and dot-addressable
graphics with four character styles.
Letter-quality daisy wheels
Daisy wheel printers give you that
crisp "electric typewriter" look. Our
DWP 520 (26-2800, $995.00) prints
up to 500 wpm. Or try the DWP 230
(26-2812, $399.95) for economical
letter-quality and up to 200 wpm.

Although mostly for fun, the following program may help
you make a decision, if it's not too serious. It is designed to
help you determine which of a large number of alternatives
is most desirable.
Upon running, the program asks you to input alternatives.
Let's say, for example, you can't decide which video game
to buy and you have narrowed your selections down to the
following: The King, Astro Blast. Berserk, Colorpecle, Lunar
Rover Patrol, Ghost Gobbler and Sea Dragon. Input the
selections and when the last alternative has been entered,
press ENTER.
At this point, you are given the opportunity to make
changes and/or add any new items; then the decision-making
process begins. All items are compared to the others without
repetition. Simply press I or 2, depending on which item you
prefer. When all the alternatives are matched and you have
made your decisions, the results are displayed. The alterna-
tives are listed from the choices you made, ranked in order
Of the number of times you selected them. Ties are identified
and ranked the same.

♦ ♦ ♦ best of everything !
Unleash the true potential of your
Color Computer with accessories
from Radio Shack.
Add a pair of joysticks (A, 26-3008,
Pair/$ 19.95) for fast 360° movement
or our Deluxe Joystick (B. 26-3012,
$29.95) that adjusts to your touch, al-
lowing "fine tuning". For maximum
control of games and graphics, simply
"roll" the Color Mouse (C, 26-3025,
$49.95) across a tabletop to accu-
rately position the cursor.
Maximize your Color Computer's
power with the Multi-Pak Interface
(D, 26-3124, $99.95). You can change
programs instantly using the selector
switch, or under program control.
And you can connect disk drives or
other accessories, too.
Here are two more great-sounding
accessories! The Sound/Speech Car-
tridge (E, 26-3144, $79.95) adds
three-voice sound and text to speech.
The Orchestra-90 CC (F, 26-3143,
$79.95), lets you create electronic
music and sound effects.
The 300-baud DC Modem Pro-
gram Pak (G, 26-222S, $89.95) makes

assette Organization
By J. E. Rittenhouse
Tape Menu is a simple utility for cassette organization. It
allows you to list all the programs filed on a cassette, assign
each a program number and automatically CLOAD a specific
program by simply pressing a key.
To set up Tape Menu, enter the program names in the DATA
statements in lines 40, 50 and 60. This can be done by retyping
the lines and replacing PROGRAM NAME with the actual name
of the program. Be sure to separate multiple listings in each
line with commas. If you need more room on the screen to
display your listings together, delete Line 250 (type DEL 250).
The program is designed for six program listings. However,
you can change the amount by editing lines 7 and 10 to fit
your needs:
7 DIM P$ [insert number of programs)
10 FDR X=l TO insert number of programs
To do this, type EDIT 7 and press ENTER. The original
program line will appear. Press the space bar eight times (to
reach the point you want to change) and the following will
be displayed:
7 DIM P$ (
Type D (represents delete a character) and then type I
(represents insert a character), followed by the number of
programs you want to use in the menu and press ENTER. For
example, if you want to change the number of programs to
eight, Line 7 will then look like this:
7 DIM PS (B)
You can also change a line by retyping the entire line. Line
10 should be changed in the same manner as Line 7. Refer
to your user's manual for more information on editing
functions.
CSAVE"TAPEMENU" at the start of each cassette you want
to organize. Then CSAVE each of the programs in numerical
order as they are listed in lines 40, 50 and 60. Note: Instead
of assigning each program a code name, use the listing
number. For example, use CSAVE"1", CSAVE "2", CSAVE"3",
etc. Again, you can add new programs to the list by changing
lines 7 and 10, and add new DATA statements for the
additional programs. When saving Tape Menu, be sure to
leave a short blank space following it on the tape in case you
need the space to add additional DATA statements later.
Using Tape Menu may seem a bit bothersome to set up
initially, but once you have organized all of your tapes in this
manner, all you will need to do is load and run Tape Menu,
and input a selection; the program will automatically be
loaded.

The following utility uses the CoCo's single-bit sound
capability to create a click sound when any key is pressed
on the keyboard.
Upon running Key Beep, you are asked to input an address
where the machine language is to reside. (Use &H0FFF as
an example.) The ML portion of the program is then poked
into memory and executed.

Echo allows you to get a hard copy of your session on the
CoCo. The program gets its name from its ability to echo
any character printed on the screen to your printer. To do
this the program intercepts your CoCo's output routine using
a RAM hook at Memory Location 360. It checks to see if
a character is being sent to the screen and then sends the
character to the printer and then back to the screen.
If you have Extended Color BASIC, after running, you can
start Echo working by typing fl=USR0(0) and pressing
ENTER. The printer will start printing everything that is on
the screen. To stop the echo function, type fi=USRl(0) and
press ENTER.
If you do not have Extended Color BASIC, you must use
the EXEC command to get Echo to work. First, delete lines
80 and 90. Then, to start Echo, type EXEC 512 and press
ENTER. To stop Echo, type EXEC 53? and press ENTER.
Note: Be sure your printer is turned on and the baud rate
(600 baud: POKE150,B7; 1200 baud: 150,41; 2400 baud:
POKE 150, IB; 4800 baud: POKE 150,7; 9600 baud:
POKE150 , 1) is set before you run Echo or your computer will
lock up.

Everyone is saving for one thing or another. Maybe it's an
official Donny and Marie pup tent or perhaps a Davey
Crockett coonskin cap. Or maybe it's something practical,
like the new CoCo 3. In any case, you'll want to know how
long you have to save before you can actually buy. Savinfor
will tell you exactly that, down to the week, or any part
thereof.
Simply follow the prompts. When inputting money
amounts, don't use the dollar sign ($). If you are entering
amounts under a dollar, like 37 cents for example, input . 37.
Afteryou input the amount earned from your allowance and/
or job, you are asked how much you want to keep each week
for spending. Obviously, the amount you want to keep can't
be larger than the amount you earn. If you try to do this,
a message will appear telling you just that — which proves
you can't spend more than you have . . . unless, of course,
you have a charge card.

issue of the rainbow in your mailbox!
RAINBOWfest is a great opportunity for com-
mercial programmers to show off new and inno-
vative products for the first time. Chicago is the
show to get information on capabilities for the
new CoCo 3. In exhibit after exhibit, there will be
demonstrations, opportunities to experiment
with software and hardware, and special RAIN-
BOWfest prices.
Set your own pace between visiting exhibits
and attending the valuable, free seminars on all
aspects of your CoCo — from improving basic
skills to working with the sophisticated OS-9 op-
erating system.
Many people who write for the rainbow — as
well as those who are written about — are there
to meet you and answer questions. You'll also
meet lots of other people who share your interest
in the Color Computer. It's a person-to-person
event and a tremendous learning experience in a
fun and relaxed atmosphere.
To make it easier for you to participate, we
schedule RAINBOWfests in different parts of the
country. If you missed the fun in Princeton, why
don't you make plans now to join us in Chicago?
For members of the family who don't share your
affinity for CoCo, RAINBOWfest is located in an
area with many other attractions.
As a new feature for RAINBOWfest, we are
planning an Educational Sandbox. This will fea-
ture child-oriented workshops to give hands-on
experience to an age group often neglected.
There will be a session for the kindergarten to
third grade set and another for fourth through
seventh graders. RAINBOWfest has something
for everyone in the family.
The Hyatt Regency Woodfield offers special
rates for RAINBOWfest. The show opens Friday
evening with a session from 7 p.m. to 10 p.m. It's
a daytime show Saturday — the CoCo Commun-
ity Breakfast (separate tickets required) is at 8
a.m., then the exhibit hall opens promptly at 10
a.m. and runs until 6 p.m. On Sunday, the exhibit
hall opens at 1 1 a.m. and closes at 4 p.m.
Tickets for RAINBOWfest may be obtained di-
rectly from the rainbow. We'll also send you a
reservation form so you can get your special
room rate.
The POSH way to go. You can have your travel
arrangements and hotel reservations handled
through rainbow affiliate, POSH Travel Assist-
ance, Inc., of Louisville. For the same POSH
treatment many of our exhibitors enjoy, call POSH
at (502) 893-331 1 . All POSH services are available
at no charge to RAINBOWfest attendees.

The CoCo Guru Has
a Mind of Its Own
My Webster 's Dictionary defines a Guru as one's personal
spiritual adviser or teacher. It also says he is a leader, highly
regarded by a group of followers and that sometimes the
term is used derisively. CoCo Guru applies only to the latter
part of that definition.
The machine language program is supplied on disk and
requires the Radio Shack Speech/ Sound Pak. No documen-
tation is provided nor is it needed to run the program. The
disk is copy-protected, and works on the CoCo 3.
Most of us think of a Guru as a wise man; a philospher
with deep religious roots. This Guru however, is nothing
more than a dirty old man who rambles endlessly about
nothing in general and sex in particular. If bad taste is your
bag, read on.
The only input you, the user, have is typing in your name.
From then on the Guru asks and answers all the questions
that are directed to you.
Often when a question is asked, you might want to answer
differently than the program allows, and that is a big flaw
in the program. You find yourself only an observer to a
conversation that leaves you speechless. The questions and
answers are totally irrelevant to anything and are sometimes
humorous. The program is structured to create random
sentences, which I suppose is why the thing is so darned
nutty. I found myself unwillingly glued to my CoCo in utter
disbelief at how really awful it was. It's like watching a Pee
Wee Herman movie; you just can't figure out how he can
make money being so downright corny. Maybe that's what
the authors of CoCo Guru had in mind when they released
it for sale. They may sell a few, but it will never be a hot
item for the CoCo as far as 1 am concerned. It's definitely
not for youngsters, either; in fact, it deserves an 'R' rating
for its many sexual innuendos and suggestive talk. On a
scale of 1 to 5 it rates no better than a 1, and that's being
generous because I like programs that use speech synthesis.
The authors of CoCo Guru would do us all a favor if they
would channel their talents toward a more meaningful
speech synthesis program. Or maybe they could rewrite this
program so that the user could type in direct responses to
the many silly questions. Maybe then I'd feel like I had some
control over what is being discussed. Maybe then it would
rate a 2.

Discover the Magical Maze
of Gantelet
Shades of Dungeons and Dragons. Gantelet, by Diecom
Products, is one of those maze-type games filled with
creatures, treasures, door keys and magic objects, including
the famous magic potion. The game requires a 64K. CoCo
and is available on tape or disk. It can be played with one
to three players. Joysticks are required to play with more
than one player. One player uses the arrow keys to move
around the maze and the space bar to fire in the direction
you are facing. The other two players use the joysticks and
fire buttons.
The game consists of a multiple-level maze. The exact
number of levels is unknown. The object is to find treasures
and advance from level to level, scoring as many points as
possible before your character dies. No mention is ever
made of escaping the maze. Each player begins with 600
"health" points. You may increase health points by finding
food scattered around the various levels of the maze,
otherwise they decrease as time goes on. When the health
points reach zero, the player is dead. The game is over when
all players have died.
Creatures move around the levels searching for players
to attack. An attack by a creature reduces a player's health
points. A special creature. Death, can drain your health very
quickly. You must avoid him at all costs. Creatures may be
shot, or all creatures and creature generators on the screen
may be destroyed by using a magic potion if you happen
lo have found one. Other objects have magical qualities for
the players to discover.
If you find a key you may walk over it to pick it up. It
may then be used to open a door which consists of a series
of blue squares. I never have much luck with artifact colors
so my doors were always green. Entering an "exit" square
moves a player to the next level, while entering a "telepor-
ter" moves the player to another place on the screen on the
same level. If more than one player participates, all players
must be in the exit before anyone is placed on the next level.
The game is well-done and provides quite a challenge,
especially on the higher levels where more creatures exist.
The characters respond a little sluggishly lo the joysticks
and may take some getting used to, but this was not a serious
drawback. All players must remain visible on the screen at
all times. This means two players cannot go in opposite
directions in the maze because the screen cannot scroll two
directions at the same time. The screen appears to lock up
until both players proceed in the same direction. This also
takes some getting used to, as well as player cooperation.
For a gamester, Gantelet provides a thrill and a challenge.
It would make a good addition to anyone's maze collection.

The use of a graphics software package enhances this
product. Remember, though, the image printed on paper
must be the mirror image of the desired finished product.
The UNDERWARE documentation indicates that many
graphics packages include such a "flip" feature. If yours
does not, Robert C. Montowski's FLIP-L2R utility which
appeared in the July '86 RAINBOW may be the ticket.
You may want to spruce up the designs you create with
UNDERWARE ColorPens. A set of these includes red, blue,
green, orange and yellow. Whether used to decorate images
created with UNDERWARE ribbons or to create free-hand
works of art, anything drawn or written on paper with a
ColorPen becomes an iron-on transfer.
The fabric to be decorated should be at least 50 percent
polyester for best results. The documentation suggests that
your iron be set to its hottest setting. Be careful here —
experiment on an old shirt or something. The hottest setting
on my iron scorched and nearly melted the fabric within
seconds and created very unsatisfactory results. The
"permanent press" setting turned out right for me.
Both the printed images and those created with Col-
orPens transferred well. My advice regarding printed
images is the bolder the better. ColorPen creations look
much better after transferred to cloth than they do on paper.
Pen lines in filled in areas seem to disappear to uniform
color when transferred. My daughter Emily was in charge
of pens and created quite a creature from outer space!
I have a couple of questions for Diversions, Inc. Why no
ribbons for Radio Shack printers? Why no mention in the
documentation of Tandy computers and graphics software
for them?

Music Libraries for Your
Listening Pleasure
Speech Systems is well-known in the CoCo Community
for its popular music programs, voice synthesizers and
E.A.R.S. To complement these fine pieces of soft ware, what
else would a company sell? Why not sell examples of the
output of these programs. Hence, Music Libraries 400, 500,
600, 700 and 800. These packages are in addition to the
Music Libraries 100. 200 and 300.

Each Music Library contains five or six disks with over
100 four-voice music selections. The entire library is the
work of two music lovers. Volumes 100 to 400 and 600 were
transcribed and arranged by C. Clark Rulaford, and
volumes 500, 700 and 800 were compiled by Speech Systems
vice-president. Randy Spector. As a serious user of Musica.
Musica II and Lyra. I am well aware of the time and work
involved in compiling such libraries. A tip of the hat to both
these gentlemen for their fine job.
While each volume is available on both tape and disk,
I received the disk version. You are instructed to run a
program called JUKEBOXD. After doing so, you are greeted
with a two-column menu of all the selections available on
the disk. From there, you may choose to listen to a single
selection or all selections on the disk. (Musica is not
required for listening to the music in the music libraries.)
See You at
RAINBOWfest-Chicago
April 10-12
In addition, the JUKEBOXD program supports output to the
Speech Systems Stereo Pak as well as to the TV. It also
supports high-speed playing. The Stereo Pak output works
very well and, at high speed, you can sit back and imagine
you are sitting in a concert hall.
An obvious attempt has been made by Speech Systems
to ensure a variety of music styles in each volume. For
example. Volume 700 contains TV Themes, Beethoven,
Broadway, Blues, Kenny Rogers, The Beatles and Country
Classics Parts I and 2. With such a wide variety of music,
it is somewhat difficult to pick your favorites. Personally,
I never liked the "Moonlight Sonata" by Beethoven until
I heard some of the special effects introduced by the
arranger. I have listened to these five libraries in their
entirety four different times. There are very few mistakes
in transcription. I am even considering running an output
from my computer room to the stereo in the family room
just so we can listen to selections. Or, better yet, 1 may just
buy a new CoCo and set it by the stereo. With all these music
packages from Speech Systems, the CoCo is quickly
becoming an integral part of the stereo system.
The Speech Systems Music Libraries are packages that
you can really sit back and enjoy. I definitely rate these
packages a 97 out of 100. And, no single Library is better
than any other. They are all worth getting.

THE RAINBOWS
"One-Liner Contest
"has now been expanded
to include programs of
either one or two lines. This
means a new dimension and new
opportunity for those who have "really
neat" programs that simply just won't fit in
one line.
Here are the guidelines: The program must
work in Extended basic, have only one or two
line numbers and be entirely self-contained —
no loading other programs, no calling ROM
routines, no poked-in machine language code.
The program has to run when typed in directly
(since that's how our readers will use it). Make
sure your line, or lines, aren't packed so tightly
that the program won't list completely. Finally,
any instructions needed should
be very short.

Dual DOS Switcher:
Simple and Inexpensive
DDA Y : The Invasion
of Normandy
Have you ever thought about making your own custom-
ized DOS but put off the project because you couldn't think
of a neat and clean way to add it to your CoCo? I like to
build project boards, but I like them to plug in. I don't like
the idea of hacking away at the innards of my computer.
Well, 1 have some good news for you. Now there is a
simple and inexpensive way to add another DOS to your
computer — it's called the Dual DOS Switcher. It's designed
to be used inside your J&M Disk Controller. After you have
completed the installation, you will be able to manually
switch between a 24-pin ROM and a 28-pin EPROM or two
28-pin EPROMs.
Oddly enough, I found I could not install both the J-DOS
and the RS-DOS at the same time. Both of these are 24 pin
in my machine and this is one configuration the switch does
not handle.
While the installation itself is simple enough and requires
about 30 minutes to complete, the instructions may be
inadequate for those who have never attempted any
electronic modifications before.
All in all, the product works fine, and for the price it sure
beats trying to come up with your own form of "kludge"
to the system.

DDA Kfrom Ark Royal Games is an excellent historical
program that provides hours of fun. This Simulation
requires strategy and advance planning as you control the
Allies in their fight against the Nazis.
The game is simple to load and execute, and is not copy-
protected so backups can be made. After each turn is
completed, you may play on or save the setup. This is a plus
for war buffs who want to try to work different combina-
tions of forces.
DDA Y begins with the design of your invasion force. The
seven pages of documentation that come with the program
include an example run of the order of battle that is very
helpful.
The one restriction of the game is that you are only
allowed three fighter bomber squadrons. The Nazi forces
are controlled by the CoCo and, in order to get control of
the air, you must destroy at least four of the German
airfields. If this is not done quickly, your navy and troops
suffer.
DDA Y is for the more advanced player; novices may have
some difficulty getting started. Some knowledge of the
Invasion of Normandy is needed. This game rates an 8 on
my scale of 1 to 10. Now all 1 need to know is where to
put General Patton and the tanks!

Education
Breakthrough
New interactive CoCo software
makes learning easy, +'&\
fun. Kids love it! +<***
NEW LOW PRICE - 16 lessons for the price
of 8! Educational Software for kids from
6 to 18.
Parents are depending more and more on
supplemental education (or their children. Edu-
cators know that the most effective teaching is
done one-to-one. Through individual attention
and self-paced progress, students learn more
and retain more.
BETTER THAN A PRIVATE TUTOR
The Compass Education Software LOOK/
LISTEN/LEARN approach is the next best
thing to a private tutor. Unlike other educational
software the Compass Library also talks to the
student — not in synthesized speech, but in a
real human voice. With on-screen textual infor-
mation and attention-getting graphics, stu-
dents of all ages actually enjoy learning!
SELF-PACED FOR BETTER RETENTION
The lessons advance only after the stu-
dent has correctly answered the questions
throughout the programs assuring that Ihe
material has been thoroughly absorbed.
SIMPLE EQUIPMENT REQUIREMENTS
All you need is the TRS-80* Color Com-
puter (any model), computer cassette recorder
and TV set. Once the cassette is loaded you
need only enter two simple commands . . . and
then press any key to start the lesson.
Of course you can stop the lesson at any
point to study information on the screen. Just
push the pause button on the cassette player.
Push it again and lesson resumes.
To answer questions throughout the les-
son simply press the appropriate number on
the computer keyboard, type in the correct
answer, or follow other easy instructions. And
to go back and review, just rewind the cassette.
It's that simple.
CHOOSE FROM 9 SUBJECTS
There is not sufficient space in this adver-
tisement to list all lesson titles, but here is a
sample:
MATHEMATICS
In today's advanced, HiTech world, under-
standing and working with numbers is essen-
tial. Compass has developed three compre-
hensive series of math programs. From basic

CoCo III Secrets Revealed
Offers Good Information
The Color Computer 3 market is presently in somewhat
of a waiting state. Color Computer software/ hardware
vendors are busy trying to get new products for the CoCo
3 while most owners of the new machine are waiting
(impatiently) for those new products. When the new
products are finally released, I imagine there will be quite
a rush of CoCo 3 sales. However, what do we do while we
are waiting? The daring, technically-minded people who
dabble in programming will want to pick up CoCo III
Secrets Revealed, a 34-page information manual for the
CoCo 3.
The manual contains six chapters that discuss features of
the new machine, and gives a modest memory map. Chapter
1 covers the basics of the Memory Management Unit
(MMU) as well as explaining how the palette registers work.
It includes a subjective chart of what values give what colors
in the palette registers. Chapter 2 lists and briefly describes
the new commands in the CoCo 3. This really is useless,
as anyone who owns a CoCo 3 already has the manual, and
this chapter doesn't give enough specifics to help anyone
who doesn't have the new machine. Chapter 3 goes back
to discuss some of the finer aspects of altering the palettes.
This chapter also includes several "you type 'em" examples
of how to access some fancy features. Chapter 4 is a tidbits
chapter. It covers smooth scrolling of graphics, a memory
test program for I28K and 512K versions of the CoCo 3,
and several peeks and pokes to control the video output.
Chapter 5 is devoted to an eight-page memory map. This
map does not fill the need for a good disassembly of the
machine. However, it does provide a great deal of informa-
tion regarding operational "modes" of the CoCo 3 and
where to go to control I/O on the new machine. Those
technically-oriented people will be able to discern a good
deal of useful information from this chapter. Finally,
Chapter 6 is a brief summary. The last page of CoCo III
Secrets Revealed gives the pinouts for the RGBjack located
on the bottom of the CoCo 3 and also for the GIME chip.
These diagrams are rough, hand-drawn pictures which
might indicate they were thrown in at the last minute.
All in all, CoCo III Secrets Revealed offers some very
good information which will be helpful to advanced as well
as intermediate programmers. I do feel, however, the
manual could have been reduced to about 10 pages and still
contain the same amount of useful information. The price
is not too high, especially since we are all waiting for CoCo
3 products.

Physics: The Study of Motion,
Matter and Energy
The software library from York 10 Software consists of
five main courses which cover standard school curriculum.
Each study course consists of two volumes of material with
eight cassette tapes in each volume, for a total of 144
individual lesson plans.
This library is only available on cassette tape because it
contains both audio and visual presentations. The first
cassette in each volume contains the loader used to run all
of the lessons in that volume. As the loader is written in
machine language, you need to follow this procedure when
using these programs. First, insert the first cassette in the
cassette player and rewind it. Then turn on your CoCo and
monitor, and type CLOftDPkEXEC and press ENTER. When
the program is loaded and running, just follow the prompts
on the screen.
While you are using these lesson plans, you can stop the
program at any time by pressing the pause key on your
cassette player. If you don't have a pause key, just stop the
recorder. You can also rewind or fast forward the tape so
that you can review or skip any section of the lesson plan.
Physics is defined as the study of motion, matter and
energy, and their interactions. Everything in our universe
is governed by these laws. Are you curious about physics?
What are light and sound waves? How does electricity work?
For the answer to these and other questions, you can use
one of the lesson plans contained in the Physics/ Science
study course.
Volume One takes you through the study of motion,
matter, sound, light and optics, and wave motions. Volume
Two lakes you through the study of electrons, AC voltage,
solid-state electronics, the elements, atomic and nuclear
physics, and the theory of relativity.
Although the instruction book states that these lesson
plans are made so that students of all ages can explore these
concepts, each lesson plan starts out by telling you that the
study of physics is a hard subject and that you should go
back and review any previous lessons until you have a firm
grasp of the concepts discussed. I fully agree with this
disclaimer.
My son Eddie, who is 8 years old and in the third grade,
was curious about this software. One night, he sat down in
front of our CoCo and went through the Sound and the
Light and Optics lessons. Although he finished both lessons,
1 don't think he really comprehended the concepts that were
being explained. I would, therefore, suggest that these
lessons be used by students who are older.
1 tried the courses on AC voltage and solid-state
electronics. I was impressed. These courses are set up in such
a way as to explain the subject matter in a concise and
entertaining way.
If you are curious about physics and the laws that govern
our universe, then these programs will be very useful to you.

Studies in the Parables
Provides the Framework
for Bible Study
Studies in the Parables is a welcome addition to the
growing selection of Bible-based programs, and another
fine offering from the Rev. Mark S. Camp and Sovereign
Grace Software.
Like other Sovereign Grace programs. Studies in the
Parables consists of disk text files along with a printing
utility. The text files may be printed out on any word
processor or by using the built-in text processor.
There are a lot of big words one can use when talking
about the study of the Holy Scripture, but Mark Camp
doesn't use them and 1 don't either.
I will make no attempt to judge or comment on the
theology of these studies. I only want to evaluate their use
in a general way. They are good solid outlines written by
a man who knows the subject matter.
Speaking of that aspect, the Studies in the Parables are
simple, straightforward theology, written in a clear and
concise style.
This program is of great value to Bible teachers, students
and to people who may be interested in the study of
scripture. The material on the disk could be used for a series
of expository sermons on the Parables, or simply used as
the framework for further study.
Mark Camp says he hopes we will use the disk as a
"skeleton, on which (we) can hang (our) own meat." I can
see that as a very good use. Mark has essentially prepared
a good study around which we can build a commentary. The
folks at my storefront church will be having a series based
on Mark's outline. 1 suppose that is why he took all the time
to prepare the study — to send it into the world to teach.

Hint
Attractive Solution
After finding out the price of a bulk tape eraser, 1
decided there must be another way to accomplish
complete erasure of tapes. A quick look in the junk
box yielded just the right tool — a magnetic mount
for a CB antenna. Any large magnet should do. Just
rub the magnet in a circular motion several times over
the tape on both sides. You can then use the tape to
record sound or data. Though 1 haven't tried it yet,
this should also work with VCR recording tape. Be
sure to store and use the magnet far away from your
tape collection so that you don't inadvertently erase
other tapes, too.

Pick a Winner With
The Lottery Player
If you are like millions of other people, you may have
spent a buck or two on a lottery. Twenty-two states and the
District of Columbia, along with Canada and Australia, are
currently operating lotteries. Their popularity and increased
revenue are attracting more and more states to consider
them as ways to supplement declining tax bases.
Suzanne Spencer Software now offers for your 64K Color
Computer The Lottery Player, which claims to increase the
chances of winning lotteries. The program is available on
either tape or disk and is not copy-protected, so backup
copies are no problem. The purchaser should specify what
state or national lottery version is wanted when the order
is placed.
Most people who play lotteries select numbers based on
some scheme like their birthday, social security number,
address or other combination of numbers. Sometimes you
might get lucky, but the odds of winning using such picks
are very slim. Dave Gentry, the author of The Lottery
Player, has done some serious studying in the area of
mathematical probabilities and has developed a unique
computerized approach to selecting lottery picks. The
methods that Dave discusses in the 10-page set of instruc-
tions require that you utilize the method of Wheeling
Numbers. This method, along with the purchasing of
multiple Lotto tickets each week, will help you become a
winner. The author is wise to point out that while there is
no guaranteed return for the money you invest, you will see
an improvement in your winnings that can be verified before
any money is spent by keeping track of the winning numbers
for a period of time.

(For ihis winning one-liner conlesl enlry. ihc author has been sent copies
of both The Second Rainbow Book of Simulations and its companion Tlte
Second Rainbow Simulations Tape.)
The program requires that the user enter the winning
lottery numbers each week in the program's data state-
ments. In this way the computer is able to determine the
most frequently called numbers, which forms the basis of
the Wheeling system.
Wheeling systems take a set of numbers and then combine
them into various combinations of six numbers each. All
of the possible combinations are not used because most of
us could not afford the cost of the thousands of tickets
needed. There are normally 38 to 42 sets of six numbers each
that are derived, and the program produces a sufficient
number of combinations to give an increased chance of
winning. Since the odds of winning first place are slim, the
best this program can do is improve those odds and increase
your chances of winning second, third and fourth place
money. You may not win the big one but the small stuff adds
up, too!
The Lottery Player uses the abbreviated Wheeling system
so the average player can afford the cost of the weekly
lottery tickets. The program allows you to select 12, 14, 16
or 18 numbers that will be Wheeled into 38, 40 or 42
combinations of six numbers each. Three methods of
number selection are used and shown in the five main menu
options.
In Option I, you are prompted to pick up to 18 numbers
and the numbers are Wheeled.
Option 2 allows you to select the last 10-week period that
you have winning Lotto ticket numbers for. Since it utilizes
only the last 60 numbers that have been drawn, it is often
considered the best way to select the "hot" numbers. This
option analyzes the winning numbers from the last 10 weeks
and selects only those numbers which have appeared more
than twice in that period. Ticket combinations are presented
on the screen and to the printer if you want.
In Option 3, the computer generates the most frequent
numbers that have appeared between a beginning and
ending period. These numbers are then compared to the
amount of numbers you chose for Wheeling purposes and
all of the other numbers are discarded. The various ticket
combinations are displayed on the screen or to the printer.
Selecting Option 4 lets CoCo analyze any of the three
methods chosen using data from the previous weeks of
winning numbers. You can see the number of tickets
Wheeled and the cost of those tickets.
The final option sends a chart to your printer and shows,
graphically, the frequency that each number in your lottery
appeared in the previous weeks.
This program does a lot with lottery information. It
utilizes the CoCo and an optional printer to take full
advantage of the Wheeling Number System. I urge any of
you who play lotteries on a regular basis to use this program
to improve your chances of winning. With this software, a
CoCo and weekly purchases of lottery tickets, you may
become the first millionaire on your block!

Create Labels With
Ultra Label Maker
I like to think of myself as an organized and precise
individual. However, when it comes to labeling disks in my
rather large disk library or addressing a quick envelope to
RAINBOW magazine, I always seem to be just barely able to
scribble it down with my trusty, felt-tipped pen. Well, look
out world, now that I'm armed with Ultra Label Maker
from Bob van der Poel Software, no more fooling around
with handwritten scribbles. I can now, with very little effort,
create the neatest labels you have ever seen. (Last I heard,
my wife and kids were drafting a letter of thanks to Bob.)
Ultra Label Maker comes in either a cassette or disk
version, requires 32K Extended BASIC and is not copy-
protected. One of its most important features is its
compatiblity with any and all printers. Owning a DM P- 1 20,
I usually suffer heavily when purchasing any printer-related
software. This program is one of the few exceptions. The
software allows this compatibility by letting you create your
own printer driver. However, unlike some programs with
the same option, you do not have to be a programmer or
hacker to generate the driver. The Ultra Label Maker disk
also contains a program called Fontedil which takes you
step by step through the creation of your own printer driver.
Fontedit lets you set up from one to nine control code

Hardware extra
sequences for printer functions such as Italics, NLQ, Elite,
Condensed and others. What's more, when you run the
actual Label program it allows you to mix and match any
of the fonts for each and every line. It even takes into
account the different type sizes, such as "expanded" and
adjusts the number of characters allowed on the line.
The program also lets you set the size of the labels,
allowing for any size mailing label or other label on the
market. I have some rather large 5-by- 1. 5-inch labels and
it handled them perfectly. As with the font styles above, the
number of characters prompted for on each line changes
with the size of the label. Also, the data entered may be
automatically centered, left or right justified or left as is at
your discretion. Of course, each label can be saved for
reprinting or modifications at a later date.
At this point, I have described what is possibly one of
the most user-friendly and practical label-making programs
on the market today. However, Mr. van der Poel didn't stop
there, but added two more options to further enhance the
program. One option is called Merge File Print, which sets
up a label "mask" using the features I described earlier and
has the program read an ASCII file of names and addresses,
and generate a label for each. Each blank line in the mask
is replaced by a line from the ASCII file. This means you
could put fixed information in the mask to appear on every
label and input the remaining variable information from the
file. The file is easily created with any word processor
capable of ASCII output.
The other option allows each label to be printed with a
sequential number for raffle, event or hat-check tickets. The
starting number and increments are user-definable to the
point of allowing a negative increment and the placing of
the number anywhere within the label.
By now, you may have guessed that I was impressed by
this program. For those of you who have Tele Patch, also
by Mr. van der Poel, you already know the forethought and
precise planning that goes into his products. Being a
professional programmer myself, I really appreciate a
quality piece of software when 1 find it. Also included with
the program is an extremly clear and well-written manual
ranking among the best documentation I have seen in a long
time. If you need to create labels of any kind, you couldn't
possibly go wrong with Ultra Label Maker.

Hint . . .
Great Racks, CoCo Stacks
Several department stores carry small metal grid
racks that fit onto your cupboard or closet shelves.
They are intended to hold such things as plates, towels
or just about anything. With that in mind, I decided
to use one to hold my CoCo equipment. It works
perfectly! Just place it right over your CoCo (many
of them even work well if you have a Multi-Pak
Interface) and set your monitor and/ or disk drives on
them. Buy two and use one for your printer. These
racks are great and, best of all, they are very inexpen-

Get the Total Picture
With Puzzle Math
Only a generation ago one of the major ways of drilling
math facts was the use of the flash card. The problem was
written on one side of the card and the answer was on the
other. The student used the cards individually or the teacher
used them in class, many times in the form of a game. With
the advent of the microcomputer, software authors began
writing drill-type software that mimicked the flash card.
Numerous programs have been written that provide drill of
math facts. These are available either commercially or in
past issues of THE RAINBOW. Certainly, one could easily
argue that we don't need any more math drill programs.
However, for those who might be looking for a program
that would also make the process of reviewing math facts
interesting and fun for the child, consider Puzzle Math by
SECA.
Puzzle Math, which requires 64K with Disk Extended
Color BASIC and one disk drive, does everything that the
old flash cards did and more. Each time the student answers
the problem correctly, a piece of a picture (puzzle) is
displayed. Thus, there is an incentive to keep answering the
questions in order to see the complete picture. The program
disk comes with 18 pictures that the computer randomly
selects at the beginning of the program.
Puzzle Math starts out with a menu of the four math
functions — addition, subtraction, multiplication and
division. Having selected one of these functions, the next
menu prompts for the range of difficulty. There are four
ranges of difficulty, approximately corresponding with
grades two through five. The third and final menu prompts
for the number of puzzle pieces (problems), 8, 12, 16, 24
or 48.
After answering all of the prompts, a graphics screen
appears and presents five possible answers from which to
choose the correct one. If the correct answer is entered, the
screen reveals another puzzle piece; if an incorrect answer
is entered, you are given a second chance to enter the correct
answer. The program continues in this manner until all
pieces have been revealed. Then, a score card is shown that
gives the total problems attempted, number of problems
answered correctly and the number of problems answered
incorrectly.
Now you are probably thinking all this sounds great, but
what happens when the child gets tired of the 18 pictures
provided with the program? No problem! Simply use any
picture that is drawn in either PflODE 3 or PMDDE 4 by any
of the popular graphics editors. Simply rename the picture
as PICT/V.BIN, where A' is a number between one and 18,
and copy it to the program disk. Details for this procedure
are provided in the manual.
Puzzle Math is a very good piece of software that does
exactly what is claimed. The 18 pictures are very detailed
drawings that are of interest to children. One aspect that
I did not like was with the 3rd and 4th levels of difficulty
for both multiplication and division. Too many of the
problems were of the form N x 1, N/1, and N/N. In my
opinion, such problems are much too easy for a fourth or
fifth grader. Otherwise, Puzzle Math is a very good program
that 1 would recommend for young children. I should also
note that SECA includes a free box of 10 DS/ DD disks
with the purchase of Puzzle Math.

Clue Yourself in With
The Guidebook for
Winning A dventures
By Eric Tilenius
On the front cover of The Guidebook for Winning
Adventures by David and Sandy Small is a message written
in small white type: "If you haven't discovered Adventure
games, you don't know what you're missing. If you have,
you need help!" And help is just what this book is about.
In the past, lone computer Adventurers have had two
choices when baffled by some puzzling situation — scream
and try to work it out on their own, which could indeed
take months; or madly call a friend at 2 a.m. and ask for
help. Somehow, I always got stuck doing the former, as
calling friends at two in the morning provoked rather
unfriendly remarks. The matter was made worse when
Infocom entered the CoCo Adventure scene. Infocom's
games were just so wonderfully addictive, I often ended up
agonizing over mysteries for days on end. But, just as
matters seemed to get worse, they suddenly improved.
Enter The Guidebook for Winning Adventures. It gives
hints, clues, maps and outright solutions to some of
Infocom's fabulous games. These games (all available for
the Color Computer from either Radio Shack or Infocom)
are Enchanter, Infidel, Planetfall, and Zork I, // and ///.

Both the authors and I suggest not looking at the outright
solutions until you have completed the Adventure, as being
handed the solution takes all the fun out of an Adventure.
The book also offers tips on Adventures in general and
includes a brief section on how Adventure games are
written. These sections are not very detailed, but provide
a background in Adventures for those not familiar with
them.
The main bulk of this book — 299 pages, to be exact -
is devoted to giving clues to the six Adventures mentioned
above. These sections are similar to the InvisiClues booklets
marketed by Infocom. There are, however, two chief
differences between The Guidebook and Infocom's In-
visiClues: One works to this book's advantage, and the other
to its detriment. The first difference is cost. InvisiClues
provides hints to just one Infocom game and costs S7.95.
while for S9.95, The Guidebook gives hints and maps to six
games.
The publisher, however, had a problem with The
Guidebook: Namely, how to hide the clues so that a reader
didn't ruin his game by looking down a page and seeing all
the answers to all the puzzles. The InvisiClues, as its name
suggests, accomplishes this by putting clue answers in
invisible ink and providing a decoding pen. This technique,
however, would be far too costly in a 300-plus page book.
Instead, the authors provided scrambled answers to clue
questions. Thus, if you are stuck in a certain part of an
Adventure, you need only find the appropriate question in
the clue book that describes the situation and unscramble
(by means of the given key) the answer to this question.
For instance, if you were playing Planetfall and wanted
to find out how to fix the broken coolant system, you would
simply turn to the chapter on Planetfall, find the section
on The Tower Core Area (which is where the coolant system
is located), then look for the question, "How can I fix the
coolant system?" Unscramble the scrambled clue, and voila!
After using The Guidebook for a while, I soon became
quite weary of unscrambling clues by hand. That's when I
wrote the program enclosed with this review. Simply RUN
this program and type in the scrambled sentence. In the
blink of an eye, the plain English clue appears on your CoCo
screen. I also found that using this program forced me to
try a situation before turning to the book for help, since
I had to save my position in the Adventure and QUIT before
I could run my decoder. The program is a real relief if you
buy this book — give it a try.

One thing I like about The Guidebook is that it has
different levels of clues for each question. The first clue gives
a gentle nudge in the right direction, the second a big push,
and the third clue usually tells you the answer straight out.
This way, you get only the clues needed. Sometimes the first
clue is a bit sarcastic. For instance, upon de-scrambling the
first clue to the question, "What is the chemical dispenser
used for?" one is greeted with the very helpful clue,
"dispensing chemicals"!
In addition to the clues. The Guidebook offers a list oi
all the objects used in the Adventure and their purposes,
a section containing maps of each Adventure, and an "Order
of Play," which gives the complete step-by-step solution to
each Adventure.
With the aid of a couple of friends, 1 tested a major
portion of the hints given by this book and found the book
to be quite comprehensive as far as providing the answers
to any possible question a player might have. I checked the
maps in the book against those I had drawn up and found
that those, too, seemed complete and accurate.
I did come across a few errors in the step-by-step solution
section, though. For instance, under the section for
Planetfall, you are told to get out of the safety webbing after
the pod lands under water. If you wait this long while
playing the game, though, you'll never make it to the
surface. You must get out when the pod first starts to sink.
In another case, you are told to put the flask in the machine
shop, and then later told to pick it up while in the "Corridor
Junction." Boy, that flask moves fast! However, with a few
minor exceptions such as these, the step-by-step solutions
worked and even gave the correct number of points you
obtained for each puzzle.
Despite the annoyance of having to unscramble clues
(made easier by the program below), and the few minor
inaccuracies this book contains, I would recommend it to
anyone who has, or is planning on buying, any two or more
of these games. If you only have one of these games and
aren't planning to buy more, Infocom's InvisiClues is
cheaper and easier to use. However, this book is a great
companion to any Adventure game lover, and, unlike the
InvisiClues, can be passed on to a friend who is having
troubles with other games.

VIP Writer Enhancer
Provides Helpful Additions
If you use VIP Writer, this BASIC utility from Foxx
Software will interest you. It allows you to use text files
created by VIP Writer in another context, such as uploading
them to a BBS. Or if you prefer, you can download files
from another word processor or BBS and modify them for
use with VIP Writer.
VIP Writer Enhancer reads any text file from disk and
then modifies it as specified and creates a new corrected file
while leaving the original intact.
The program is very easy to use. After running it, you
are greeted with the Main Menu. A full complement of
options is available to allow you to perform other useful
disk functions without exiting to BASIC.
The first option allows you to Convert VIP to ASCII files.
Since VIP Writer does not add a carriage return at the end
of a line, problems are likely to occur when trying to upload
to a BBS or read a J 7 / /'file on another word processor. Since
each paragraph is saved as one long continous line, you'll
get a rather cluttered text file on any other word processor.
This option adds carriage returns at the line length specified
at the prompt and also enables word wrap.
The next option is converting ASCII to VIP files. It
removes carriage returns so when reading a file into VIP
Writer it will be readable again. Without this option, re-
formatting the VIP file would be a real chore.
A handy option allows you to convert to mixed-case that
modifing a file written in all uppercase and changing it to
lowercase, leaving only the beginnings of sentences
capitalized. It can't recognize proper names, though, but
you can easily correct that in your word processor. This is
nice in those cases where you downloaded a file from a BBS
that doesn't use lowercase. The next two options allow you
to convert to all upper- or lowercase. You might want to
use these options for uploading to a BBS that requires all
uppercase or all lowercase.
Remove Control Characters comes in handy when mixing
files from various word processors where control codes are
likely to be different. It's also handy for fixing downloaded
files from BBS's.
The Rename File option is like BASIC, but easier to use.
Just follow the prompts. The Kill File option is also like
BASIC, but prompts help prevent accidental killing of files.
View File displays any file on the screen. Uses the space
bar to start and stop and the up/ down arrows to go forward
or backward one screen at a time. Count File displays the
character count of any file. Drive # selects what drive your
files are in, and Exit To Writer restarts VIP Writer if a copy
of VIP Writer is on the enhancer disk, or if VIP Writer is
in Drive 0.
A feature I liked was the default file extension automat-
ically added by the program. This results in a quick and
accurate way to determine which files have been modified.
When you select any of the options you will be prompted
with FILENAME ? After the program reads in the filename,
it asks you NEW NAME ? For example, if you had a VIP file
on your disk named TEST. VIP and you selected option 1,
you would answer the FILENAME ? prompt with TEST. The
file TEST. VIP would be read in and then you would be asked
NEWNAME "> By simply typing TEST, the program adds the
extension ASC to TEST so that the new file is called
TEST.ASC,

Getting the Max
From MiniDOS 9
In this day and age when many utility programs claim
to do everything from whitening your teeth to picking up
the kids after school, it is very refreshing to see a program
developed that claims little but does everything it states —
perfectly. This program is Cir-Pak Limited's MiniDOS9.
MiniDOS9 is a utility package that allows Cir-Pak Limited's
SC68008 coprocessor card to communicate with OS-9. You
must have both the coprocessor card and OS-9 to have any
benefit from this package.
MiniDOS9 can best be described as a "mini" monitor that
allows one to communicate directly with the SC68008 card.
The monitor contains what I consider to be the core routines
that are necessary to debug software and gain an insight into
the internal workings of a microprocessor-based system.
There are essentially three types of commands that
MiniDOS9 allows you to perform: memory display and
alteration, program loading and execution, and software
debugging. All commands are one keystroke in length and
are entered from the main menu.
The memory commands allow for the displaying and
changing of single bytes, the copying of blocks of memory
from one place to another and the dumping of 80 contiguous
memory locations to the screen. Typically, one tells the
monitor which memory location he would like to work with
and then is allowed to either display the contents of that
location (or locations), change its value or bump the
memory location pointer. The program loading and
execution commands are quite simple, but necessary. One
can load data from the CoCo's memory to the SC68008 and
from the SC68008 back into the CoCo. Program execution
is also made possible.
The software debugging commands are what I found the
most useful. They allow the user to trace a program's
execution and stop at any point in the program, or to step
through each instruction one at a time. The user is allowed
to place up to five breakpoints in the code that is to be
debugged. Whenever one of the breakpoints is encountered
by the program, it halts and gives control back to the
monitor. The user can then either check the status of the
program by dumping the registers or he can manipulate the
program or address space. The program can then be
resumed with a single keystroke. If one finds that he wants
to check a particular area of the code but doesn't like the
idea of constantly setting and resetting breakpoints, he can
cause the program to go into single step mode. From here,
each instruction is executed singly and then control is given
back to the monitor. These are essential commands if one
wants to debug machine language programs.
In addition to the three types of commands, there are
provisions to execute any of the normal OS-9 commands
from the monitor. This is done by invoking the shell from
inside the monitor. Two of the normal OS-9 commands, chx
and chd, are provided directly from the monitor so that a
shell invocation does not have to take place.
To those who own an SC68008, MiniDOS9 is one of those
few basic necessities that one should not be caught without.
I had no problems with the documentation, since there was
very little printed material (none was really needed). I had
no problems with the software itself and found everything
to be exactly as I had expected.
MiniDOS9 does not claim to do everything, but what it
does do, it does very well. It is casually elegant.

Wavy Word Pak
By Marty Goodman
Rainbow Contributing Editor
• / find my Word Pak produces an
image on my screen that "waves"
slowly, but is otherwise sharp. Can this
befixed?
Bill Jackson
(BILL JACKSON)
Sacramento, CA
I have seen the same problem on all
models of Word Pak. There are two
ways to approach the fix. If you are
comfortable with modifying ML soft-
ware under RS-DOS and modifying
drivers under OS-9, you can alter the
fine vertical timing constants in the
initialization program for the Pak.
Alternately, and probably a simpler
approach, you can solder a trimmer
capacitor onto one or the other side of
the crystal of the Word Pak, going
between the lead from the crystal and
ground. Typically, one in the 5- to 25-
picofarad range will do the job. Then
adjust this cap until the waviness on the
screen goes away. (Bill Jackson gave me
this follow-up on Delphi a few days
later: "A 20 pF cap worked. My screen
now looks fine.")
CoCo 2 Upgrade
• I'm having trouble upgrading a CoCo
2A. How do I upgrade it to 64K? I

already have the two needed 4464 RA M
chips. How do I add Extended BASIC?
Gary McMillian
Battle Creek, Ml
To the left of the 682 1 chip in the front
of the circuit board is a single pair of
pads labeled J6, 64K and RAM size.
You must solder a wire between those
two pads on the board. Then replace the
two socketted 4416 chips with the two
4464 chips you bought. This will com-
plete the 64K upgrade of that board.
To upgrade to Extended BASIC, you
must first buy the Extended BASIC chip
and manual (price is about $40 from
Tandy). You must specify exactly what
catalog number CoCo you have for
them to order the right chip. Clip the
soldered jumpers Jl, J2, J3, J4 and J5
from their current 64K position setting
and solder in new jumpers in the 128K
postion. J2 through J5 are located
together side by side, and Jl is located
a little farther away. All are near the 24-
pin ROM chip that is sitting in a 28-pin
socket. Remove the old ROM chip and
replace it with the 28-pin ROM you
bought. This completes the upgrade to
Extended BASIC. Note that the "64K"
and "128K" on Jl through J5 refer to
the number of bits in the ROM chip,
and do not refer to any 128K memory
upgrade for the CoCo 2!
Multi-Pak Extension Cord
• I just bought a Multi-Pak, and find
it does not quite fit on my desk with my
CoCo. Where can I get an extension
cable so I can position it on a shelf
above my computer?
Tom King
(CAPNCRUNCH)
Winter Haven, FL
1 strongly urge you not to use such an
extension cable. Though they are made
and sold, using one can decrease the
reliability of the operation of your
computer. The unbuffered bus of the
CoCo was not designed to have its
signals sent down several feet of ribbon
cable. Note that some CoCo systems
will appear to function fine with such an
extension cable, but I would not trust
such an arrangement.
Double-Sided, 80-Track Drives

track drives. Where can I get one, and
what software will I need?
Reuben Pressor

OS-9 is well-suited for using a variety
of disk drives, including the 80-track,
double-sided variety. These are sold
from many different venders, including
True Data Products, who advertise in
rainbow. You will need to install disk
device drivers and descriptors appro-
priate for 80-track drives. These can be

Hot-Running SAM Chips

about the old SAM chips that run hot.
I will be making some heat measure-
ments on mine soon.
Damon Hill
(DWH1LL)

THE RAINBOW February 1987
I am told that Motorola made a
number of changes in the mask of the
SAM chip over the years. The early
ones seemed to run much hotter than
the later ones, and certainly were more
likely to cause subtle crashes on the
CoCo, particularly during disk I/O due
to less than perfect internal timing.
SAM chips made after January 1984
were of a significantly superior mask
than their predecessors. The new SAM
chip used in 'A' and 'B' model CoCo 2s
(the 74LS785) is significantly better
than the old 6883 (74LS783), and it is
usable in the older units. But, of course,
if your CoCo 1 or 2 is working fine right
now, I do not advise changing the SAM
chip.
Looking at RGB Monitors
• For my CoCo club, I am evaluating
different brands of RGB analog mon-
itors for possible use with the CoCo 3.
What should I look for? Stripe width,
bandwidth, or what?
Joe Register
(MAG US II)
Naperville, 1L
With color monitors, stripe width (or
in the case of super-fine monitors, dot
pitch) in millimeters correlates in some
degree to the sharpness of the image.
The CM-8 has a dot pitch of .52 mm.
The Magnavox 8CM5I5 (professional)
monitor that is becoming popular with
Color Computer 3 users offers a dot
pitch of .42 mm. The Magnavox
8CM643 has a stripe width of .39 mm.
The Teknika MJ305 offers a stripe
width of .41. The Magnavox 8CM505
model offers a dot pitch of .65 mm.
There are many other factors in-
volved in determining what the image of
a monitor looks like. These include anti-
glare properties, number of video input
signal connections, flatness of focus
from edge to edge, and linearity. If the
stripe widths are similar, there is no way
to be sure which monitor looks better
unless you look at the display on them
yourself.
The Magnavox and Teknika units
mentioned all offer compatibility with
CoCo Is and 2s, VCRs, and IBM PCs
(they possess RGB 1, RGB A and com-
posite video input capability). The CM-
8 can be used only with a CoCo 3, and
cannot show artifact colors on CoCo I
and 2 software. The Magnavox
8CM515 also offers excellent anti-glare
coating.
Bandwidth is a figure that relates to
the ability of the electronics at the input
of the monitor to respond to a rapidly
changing signal. Typically the band-
width of the monitor will be more than
adequate for it to display an image to
the full capability of the resolution of its
picture tube, as measured in stripe
width or dot pitch.
A rule of thumb suggested to me by
Ed Ellers: Monitors with stripe widths
greater than .50 mm are really not
suitable for resolving 80-column text.
The 8CM505, with a stripe width of .65
mm, turns out to be unusable in most
of the CoCo 3 80-column modes. It does
resolve 320-by-200 graphics quite
nicely.
Hooking Up 3'/2-Inch Drives
• Is it possible to hook a 3'/2-inch drive
to the Color Computer? If so, what
steps are necessary?
George Ellenburg
(ELLENBURG)
Edgewood, FL
The 3'/2-inch disk drives are the exact
electronic equivalent of 5',4-mch, 80-
track, double-sided drives. Both have
720 K. data storage capacity. The signals
on all of the lines of the 3'/4-inch drive
are identical to those of the 514-inch
drive, so the two are electronically
interchangeable. The only electrical
problem is that 3'/2-inch drives use a
dual-row header connector (two rows of
1 7 pins in parallel) instead ofthe341and
edge card connector that is standard on
5!4-inch drives. Thus, you will have to
make up or modify a cable on your own.
The connector you need is a female 34-
pin, dual-row header IDC-type connec-
tor; Radio Shack sells it as part number
276-1525. There are usual considera-
tions of setting the drive to respond as
the drive number you want it to be, and
of resistive termination of the drive
cable, as with 5!4-inch drives. I recom-
mend using 3'/2-inch drives under OS-
9 with disk modules designed to use all
80 tracks and both sides. Be sure you
have one 40-track (preferably double-
sided) 5'/4-inch drive in the system to
allow you to read disks other CoCo
users and producers are still using. The
3'/2-inch drives are fast becoming the
industry standard for replaceable media
drive systems.
Use of the full capacity of 80-track.
double-sided drives via RS-DOS is
rather difficult. You can use such drives
as single-sided, 35-track drives under
RS-DOS, with no modifications to
either the operating system or the drives
(you'd merely be using the first 35 tracks
on Side 0, and ignoring the remaining
80 percent of the drive's capacity). With
minor modifications to RS-DOS (such
as an ADOS EPROM), you can also
use them as 35- or 40-track, double-
sided drives.
J&M Controller Fix
• My J&M JFD-CoCo does not work
with my CoCo 3. Can you tell me how
to fix it?
Gil Winograd
(demonn)
Glen Ellyn. IL
You need to de-solder UI1 (the
74LS04 chip) from the board and re-
place it with a 7404. The problem is that
the gate on it used to supply the SCS
line to the controller chip (pins 1 and 2
of the 7404) offers just a shade too much
delay, and this causes problems. For
those of you who are not hackers
equipped to de-solder and replace chips,
J&M generously offers to make this
repair for $5 plus the cost of two-way
shipping of your controller. Contact
them for details. J&M has been very
conscientious in both working hard to
find this problem and offering a fix to
the public at a nominal cost. I applaud
their efforts.

HARDWARE PROJECT
The CoCo ROS, Part III:
The Robotics Program and Interfacing
How that you've built and tested the
CoCo ROS hardware, it's time to
show you how to interface it to the
Robotix R-2000 robot kit and present
the program that allows you to use it.
With the ROS program, you'll be able
to write ROS macros to activate
robotic-type toys, electric train layouts
or even your own robot if you decide to
build one.
The ROS System
The ROS program is actually two
separate programs. The first is a BASIC
program (Listing 1) that allows you to
load the machine language program,
and to load and save ROS macro files
to cassette. It also allows you to clear
the ROS file buffer. It's menu-driven
and self-explanatory. To use the ROS
program, type CLDflD "ROBOT" and
press ENTER. The program loads and
executes the machine language program
for you.
The second program (Listing 2) is the
machine language program which was
originally written in PASCAL. This pro-
gram is also menu-driven. It allows you
to write, edit, test and execute the ROS
macro files.
Let's take a look at each command
listed on the ROS program menu.
Append — adds lines to an existing
ROS macro file. Enter X at the instruc-
tion prompt to exit the Append mode.
Delete — deletes lines from an exist-

ing ROS macro file. To terminate the
delete mode, enter zero (0) for the line
number when prompted.
Edit -changes an existing command
in an existing ROS macro file. This is
not a true editor. Because of the simplic-
ity of the ROS program, you must
retype the entire macro line. Enter a
zero for the line number to exit the Edit
mode.
Insert — inserts lines in an existing
ROS macro file. Enter a zero for the line
number to exit the Insert mode.
List — lists ROS macros resident in
memory to the screen.
Print — lists ROS macros resident in
memory to the printer.
Quit — returns to BASIC. You must
load and save ROS macro files from the
BASIC program.
Run — executes an ROS macro file.
Test — use this command to test an
ROS macro file. Press the space bar for
each command in the file. This steps the
macro through each command so you
can observe its effect.
Write — writes a new ROS macro
file. It starts at the beginning of the ROS
buffer. Any macro lines in the buffer
will be overwritten when the Write
command is executed.
ROS Macro File Structure
The ROS macro file is stored in
graphics addresses 1536 to 7679. Each
ROS macro line requires five bytes of
memory. The ROS program encodes
macro instructions and stores them in
five bytes during the Write function,
and decodes and executes them during
the Test and Run functions. You can
create ROS macros with more than
1,200 commands per file. If you PCLEflR
B before loading the BASIC program.
you can create macros twice as large.
The five bytes per macro line are used
as follows: Instructions are stored in
bytes I and 2 as an address. The device
is stored in Byte 3 as a power of 2, and
the duration is stored in bytes 4 and 5
as a decimal value from to 16383.
ROS Commands
There are only five commands avail-
able for use in ROS macros. Because the
ROSSP is powered from the CoCo,
power requirements must be kept to a
minimum. Therefore, only one move-
ment can be executed at a time. How-
ever, the five commands allow some
versatility. The basic command syntax
is instruction, device number, duration.
The ROS command Forward is used to
turn on the specified motor in the
forward direction. For example FOR-
WARD 2 10 turns on Motor 2 for an
internal count of 10. Reverse is used to
turn on the specified motor in the
reverse direction. It is similar in struc-
ture to the Forward command. Halt
causes macro execution to stop for the
specified duration. The device number
is not used in this command. Until
executes the command following it until
the specified device (input) goes low.
Example:
UNTIL
FORWARD
3
5
This example causes Motor 5 to turn
forward until Input 3 goes low. Notice
that the duration is not used in either
of the two commands and, finally, the
command Wait stops macro execution
until the specified device (input) goes
low. This allows the ROS macro to be
synchronized with mechanical equip-
ment.

Writing an ROS Macro
When writing an ROS macro, you're prompted for all the
inputs. Let's enter a sample macro to see the structure.
You enter:

FORWARD

X
This example shows the macro lines you might enter to
program a robot to do some simple task. The first three lines
tell the ROS to activate Motor 3 in the forward direction for
a count of 12. The next three lines tell it to activate motor
10 in the reverse direction for a count of 22. The next four
lines tell it to activate Motor 3 in the forward direction until
Input 1 goes low. The last line tells the ROS to exit the write
or append mode. The ROS macro is now in memory and can
be tested or saved to cassette.
Testing the Macro
After writing an ROS macro, test it to check its accuracy.
Select the T option from the ROS menu and press ENTER.
When you're ready to execute the macro, press the space bar.
The first macro line will be displayed on the screen and
executed. Press ENTER to display and execute each line of the
macro. The macro will continue to loop through itself until
you press N to end the test mode. Use the Edit, Delete and
Insert modes to make necessary macro corrections.
Executing the Macro
Execute the macro by selecting R from the ROS menu and
pressing ENTER. This mode automatically executes each

Interfacing the ROS
I connected my ROSSP to a small robot arm I created
using the Robotix R-2000 kit from Milton Bradley. Figure
1 shows the schematic representation of the Robotix switch
circuit board and how it's wired to the ROSSP. Figure 2
shows the actual circuit board. This board switches between
+3 volts and -3 volts to activate forward and reverse
movement. Leads M I through M5 are the battery leads going
to the motors. Leads GI through G5 are the ground leads
to the motors. The red lead on the right side of the schematic
is the reverse direction lead and the black lead is the forward
direction lead. The white lead is ground.
Using a short piece of cable and a connector, wire the M 1
through M5 battery and ground leads to the ROSSP relays
as shown in figures 3 and 4. Notice that the switch side (SI)
of the motor is connected to both the forward relay (K1F)
and the reverse relay (KIR). The connector must be
unplugged when the ROSSP is inserted in the ROM port and
power is applied. Otherwise, the +3 volts and -3 volts will
be shorted together. The ROS program will instruct you when
to plug in the switch circuit. Figures 3 and 4 explain all the
lead and component designations.
Because of the inaccuracy of the motors supplied with the
kit, 1 cut cams of thin plastic and mounted them on the motor

shafts. These cams were used to operate microswitches
connected to scan buffer inputs (see Figure 3). Using the Until
command, the microswitches provided fairly accurate arm
positioning. I was able to move a small plastic box back and
forth from one spot to another automatically for several
hours.
More Options
The ROSSP circuit can be used in other applications by
modifying the circuit. Figure 5 shows an alternative method
of connecting relays with a low coil resistance. If you use that
type, you will need an external power supply. The transistors
QIF and Q1R act as low current switches. A logic high
applied to the base of the transistors causes them to conduct.
This places ground at the bottom of the relay winding and
the relay operates. Resistors RIF and RIR are current
limiting resistors.
Figure 6 shows alternate methods of interfacing inputs and
outputs to the ROSSP. With some experimentation, you can
connect almost any type of peripheral device you can think
of. Figure 7 shows the motor assignments for the 8255 PP1
chips, the instruction, addresses and values used to write the
ROS program. Using that information, you can write your

own ROS program. By using a combination of inverting and
non-inverting buffers for inputs and outputs, you can turn
on or off any electrical device using digital signals.
Optoelectric devices such as infrared detectors and source-
detector LEDs could replace microswitches as position
detectors. If signal polarity is a problem on the scan buffer
inputs, replace the 74LS244s with 74LS240s to invert the
input signal. Likewise, by replacing the 74LS240s on the
distributor outputs with 74LS244s, the motors would operate
until the bit for that motor was set high. Be careful not to
operate the forward and reverse relays at the same time if
they are used as shown in the schematic. That would short
the +3 volts to the -3 volts and could lead to disaster.
1 hope this information has been of interest to you. It's only
a starting point for those really interested in experimenting
with computers. The CoCo offers such easy interfacing to
peripheral equipment it's a shame more people aren't taking
advantage of it. Using a circuit similar to the ROSSP, we've
used the CoCo for everything from a simple robot CPU to
a complex industrial security system. Why not try your
engineering ability at designing CoCo projects for interfac-
ing?

WISHING WELL
A Spelling Program That
Speaks for Itself
By Fred B. Scerbo
Rainbow Contributing Editor
Editor's Note: 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 that
this is BASIC. All programs resulting
from your wishes are for your use, but
remain the property of the author.
Approximately two years ago,
Tandy introduced the Speech/
Sound Pak for its Color Com-
puter line. While several other models
were already on the market, some at a
considerably lower price, Tandy re-
leased this little wonder that was ca-
pable of working as a free-standing add-
on. No machine language driver needed
to be loaded into this ROM pack, as
some other models required. The voice
was clear and realistic sounding and it
only took a few lines to incorporate the
synthesizer into your BASIC programs.
Fred Scerbo 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.
The Speech/ Sound Pak still remains
part of the Tandy catalog, while some
other earlier, independent models are
now hard to find. One void still remains,
however. Owners of this Pak still do not
have enough software to meet their
needs or appetites. Therefore, at the
suggestion of Mr. Don Andreatta of
Houston, Texas, this month's "Wishing
Well" returns to the field of artificial
voice synthesis by introducing a new
program. Hear It and Spell It.
Why a Talking Speller?
When I began learning BASIC pro-
gramming after buying my first CoCo,
a number of programs were provided as
standard introductions to the world of
programming. One was, "Let's design a
program that simulates the rolling of
dice!" Another hot ticket was a simple
"yes/ no" or "true/ false" format for
tests. The third biggest item covered in
training books was usually some kind of
spelling test. I combed through these
books trying to find anything I could
use in my classroom, especially a decent
spelling program.
There was usually one problem with
all of these simple basic programs:
None of them was really very effective
for drilling or quizzing in spelling. The
main reason for this shortcoming is the
fact that there is no effective or realistic
way to portray the word to be spelled
without actually displaying it on the
screen. There have been many noble
attempts, however.
Some programmers have written
variations on the TV game shows.
Password or Wheel of Fortune. There
have been other efforts such as Hang-
man or Tri- Planetary Hangmenoids
(from an earlier "Wishing Well"), which
involve a hit or miss approach to guess-
ing what word has been selected by the
computer. Since in spelling we are
trying to arrive at the correct letter-for-
letter version of a word, a hit or miss
approach is not the best idea.
There is really only one way to cor-
rectly teach, drill and quiz spelling. That
technique is to have the word pro-
nounced to the person trying to spell it.
That is the way teachers have done it for
centuries. The advent of microcomput-
ers is no reason to abandon a successful
method. Instead, the improvement of
artificial speech in home microcomput-
ers has given us a better reason to adapt
this new technology to the old tech-
nique, rather than vice versa.
That brings us to this month's talking
program: Hear It and Spell It. Designed
with these thoughts in mind, H&5PELL
(its BASIC filename) offers home users a
166
THE RAINBOW February 1987
r Your CoCo
greets you
with each new
word and
recites it twice
before asking
you how to
spell it."
catchy update of the old spelling bee.
Granted, many users may have already
come up with their own talking spellers
upon purchasing the Tandy synthesizer.
However, I have attempted to make the
program as classy and simple as possi-
ble, while still retaining the flavor and
feel of our usual "Wishing Well" offer-
ings.
The Program
H&SPELL will fit in a standard I6K
CoCo with Extended Color basic, (h
may also work on a 16K Color BASIC
machine, but I no longer have one to try
it on. All my machines were upgraded
long ago. Sorry, all you MC-10 users!)
As you start to type in the listing, you
will notice that between lines 9 and 10
there appears to be a strange space
without a line number. To get this effect,
when typing in Line 9, simply advance
the space bar until the line appears
exactly as shown on the 32-column
listing in the magazine. You may then
type in the string of '*'s for our border.
The title card is made from our
Tillemaker from several issues ago.
Every month I get letters from readers
who say they get an OD Error when
running one of these listings they have
typed in. Once again, let me remind you
that the DATA statements at the begin-
ning of the listing must be typed in
exactly as you see them. Leaving out so
much as a comma will cause the pro-
gram to choke. Therefore, please be
precise when typing in the program.
One of the first subroutines in the
program consists of the actual lines
suggested by the instruction manual
that comes with the Speech/ Sound Pak,
with a few minor changes. Many of the
instructions needed to run the program
will also be spoken by your CoCo as the
program begins. Remarks such as,
"Press ENTER to continue" are actually
spoken. Anytime a phrase needs to be
spoken, it is given the value of AS and
sent to the subroutine that activates the
SPEECH (GOSUB 105).
One thing you will notice is that all
my speech strings (AS) are written out
phonetically. For example, my last
name, Scerbo, is written as Skerbo.
While the Pak is usually very accurate

Here are two related one-liners from the same

same task, except that output will be in hexadecimal
form. A simple edit here and there will cause the
output to go to your printer.

in pronouncing a string you give it,
there are just some combinations it
cannot get. That is why for each word
we want to have spoken and then
spelled, we must supply the correct
spelling first, followed by the correct
pronunciation.
The words we want to try in our
spelling drill will be included starting in
Line 1000. The correct entry for putting
in your own words is:
1000 DATA SPELLING,
PRONUNCIATION
with the last line being:
5000 DATA END, END
The program is designed to handle 40
spelling words (41 counting the END
statement that is our flag to stop reading
data). If you want to increase the
number of words, increase the value of
SW in Line 70 to be one more than the
number you want. (If you want 100,
then SW=101.)
Be sure to save the program before
trying to run it. A mistake in the POKE
statements at the front of the listing
could lock up the machine and cause
you to lose your whole program. There-
fore, save it first.
Running the Program
I am not going to take the fun out of
running the program by printing out
everything the program says when you
run it. You will be able to tell either
when you type in the listing or when you
run it for the first time. You can advance
from the titlecard by pressing ENTER.
Your CoCo greets you with each new
word and recites it twice before asking
you how to spell it. A set of '*'s corre-
sponding to the number of letters in the
word appears. You will also notice that
the set of color borders on the screen
changes with each new word. An arrow
flashes below the letter to be attempted.
If at any time you want to hear the
word again, just press the space bar to
have it pronounced again. As you select
each letter to try, your CoCo will say the
letter. If you are not correct, it will say.
"No, not J" or whatever letter it is you
pressed. Be sure not to type the letters
in too quickly, or you may get ahead of
the program. There is sometimes some
delay when calling the sound subrou-
tine, so typing too fast can mess you up
if you make a mistake.
Once the word is correctly spelled, it
is repeated and the program spells the
word out loud while flashing each letter.
This serves as a good reinforcer of the
actual spelling because the user sees and
hears the words spelled right on the
screen.
As with all my programs, pressing @
gives you the score card. You may press
Y to rerun, N to stop or C to continue
with the word you were working on.
Any error in the spelling of a word will
count the whole word as wrong. (Sorry,
but that's the way it is with real spelling
tests, too.)
The order of the words will be differ-
ent each time you run the program.
Remember, putting in too many words
will make the program an absolute
torture for any child to use. (Would you
want to sit and spell 100 words on the
computer? Keep it simple.)
Try Some Other Words
You will notice I only included 10
words in the sample listing. Here are a
few more suggestions you can try in
place of the ones in the listing. Be sure
to type DEL1000-4999 and press ENTER
to delete the words in this listing if you
already have the program saved with
these words.
While some words may be listed
twice, since the spelling and pronunci-
ation are usually the same, here is a
short list of some that do require pho-
netic changes:
1000 DATA CHILDREN, CHILL DREN
1010 DATA TOMORROW, TO MORROW
1020 DATA NINETEEN, NI NTEEN
1030 DATA BREAKFAST, BREKFAST
1040 DATA FEBRUARY, FEBUARY
1050 DATA WEATHER, WETHER
10G0 DATA ONIONS, UNYUNS
1070 DATA SWEATER, SWETTER
10B0 DATA HEALTH, HELTH
1090 DATA AMERICA, AHMEHRIKA
5000 DATA END, END
You can get the proper rhythm in the
pronunciation by adding spaces as
needed in the spelling. If you would like
to see some good examples of the need
to use phonics in the pronunciation, try
the spelling words for these states:
1000 DATA MINNESOTA, MIN EH
SO TA
1010 DATA ILLINOIS, ILLINOI
1020 DATA PENNSYLVANIA,
PENNSYLVANE E AH
1030 DATA CONNECTICUT,
CONNETTICUT
1040 DATA HAWAII, HA WHYEE
1050 DATA IDAHO, I DAHO
10G0 DATA MISSISSIPPI,
MISSISSIPPEE
1070 DATA GEORGIA, GORGIA
1080 DATA 0HI0,0 HI
1090 DATA UTAH.U TAHW
5000 DATA END, END
Some of the states actually work out
OK, but these can be a real pain. If you
need to check the correct pronunciation
of a word as you are typing in the list,
run the program with some words in it
and press BREAK. Take the spelling you
would like to use for pronunciation and
make it equal to AS, such as:
A$="BAHLONEY"
Press ENTER and then type in:
GOSUB105
Then press ENTER again. If you didn't
quite hear it, then GOSUB105 again. You
can repeat this process until you get the
sound right. Then type it into the DATA
line as needed. Remember, always put
the correct spelling first and the pronun-
ciation second. Last of all, always
remember to include Line 5000 DATA

Conclusion
Next month, we will try another new
approach to your ideas, maybe even
with artificial sound again. Let me
know how well this program works for
you, and keep your suggestions com-

Editor:
I have a few complaints about Four Star
Software and Penpal. I purchased Penpal
early this year and had only one problem at
first, and that is the same one that Graham
Langford wrote about in the November
issue.
Occassionally when you press the A it
instantly prints a@a@a@, or ihihih when
the 1 is pressed. 1 wrote to Four Star about
this, but got no response.
The next problem I had was when I tried
the Sort routine in the database module. It
does not use the computer's memory at all
to sort and does all the sorting by accessing
the disk intermittently. A sort of 120 items
took 15 minutes. I did another sort and
about halfway through, the drive crashed
and I got a File Structure Error.
The next problem was when I bought a
new Dual TEAC drive. When I tried to load
a file from one of the modules 1 kept getting
a Drive Not Ready error. I found out that
if I quickly pressed the load function imme-
diately after getting the error that the file
would load. As long as the drive was still on
from the first try, it would work. Needless
to say, it was very difficult to type in a file
name the second time before the drive shut
off. It seems that the program simply does
not give the drive enough time to come up
to speed, even though it seems to almost
instantly. „ „

TURN OF THE SCREW
The CoCo Is Music to the Ears
By Tony DiStefano
Rainbow Contributing Editor
Along time ago, I did an article on an analog-to-digital
converter. I explained that you can take a varying
signal and convert it into a digital value from to
255. This time I'll do the opposite.
This month's project is called a D-to-A converter, where
a digital value from to 255 is converted into an analog
voltage. But that is just part of it. I'll show you how to make
two of these things. With two of these and some software,
we will be able to make music in stereo. Our scenario starts
by making two D-to-A converters. Then, with a couple of
preamps, some connectors, a stereo system and some
software you'll be playing computer music. We'll start today
with the D-to-A converters and finish up next month with
the preamp and some music software.
You can buy a complete, two-channel D-to-A converter
chip, but they are a little expensive and most require three
voltages. This is a problem with the one-voltage CoCo 2 and
3. Besides, it's more fun building your own. Now, let's get
into some theory on D-to-A converters.
Remember that a digital value from to 255 is made up
of eight binary bits. Each of these bits has a value of
(ground) or I (5 volts). If you use every combination of eight
bits, you come up with 255.
Let's introduce another component: a resistor. Yes, the
good ol' resistor. If you put a voltage between the two points
of a resistor, you could measure the voltage across it. If you
put two resistors in series (Figure 1 ) and measured the voltage
across both resistors, you would get the voltage that you put
in. For instance, in Figure 1, if you put 5 volts across both
resistors, you would measure 5 volts. If you measured across
just one resistor, you would get a value somewhat less than
5 volts. If you measured the voltage across the second resistor
and added that value to the value of the first, you would get
5 volts. The voltage is divided between the two resistors. If
you had three resistors, the sum of the voltages of the three
would add up to the total voltage applied. It is a simple
mathematical equation and it depends on the resistance value
Tony DiStefano is a well-known early specialist in computer
hardware projects. He lives in Laval Quest, Quebec.
of the resistor. In a resistor circuit, the higher the resistor
value, the higher the voltage across it.
If we had 255 different resistors hooked up to a voltage
and were able to control which resistor had the voltage on
it, we would have an acceptable D-to-A converter. But I'm
sure you don't want to hook 255 resistors to some circuit.
Well, you don't have to. All you need is nine resistors: eight
for the eight data bits and one used as a voltage reference
or source. It is used as a divider. This is commonly known
as a resistor ladder.
If we use that theory, plus a bit of computer theory, we
can convert a digital binary value of eight 0- and 5-volt levels
to an analog level. A computer's data bus is continually
changing as the computer does its thing. In order to isolate
an eight-bit value, a latch is needed. The easiest place to add
a latch is on the cartridge port. So, get out the tools and let's
get started.

You will need all the usual things for a project. A
protoboard, sockets, wire and a few parts. The first two parts
are not that hard to find. A good electronics hobby shop will
have them. They are a 74LS138 and a 74LS273.
You will see the circuit and how to hook it up to the CoCo
bus in Figure 2. If you want stereo or two channels, you will
need another 74LS273 and another nine resistors and
capacitor. In fact, this circuit can have as many as four
channels of D-to-A. All are identical to the one in this
diagram except where Pin 1 1 connects to the 74LS138. Also,
nine resistors are connected to each 74LS273. The diagram
shows how to connect the other three circuits. The output
of this D-to-A converter is about .1 volts on the low end and
about 4.9 volts on the high end. The capacitor is used for
high-frequency roll-off and to dampen switching noise.
So far, there haven't been any problems, but notice that
I haven't given any resistor values. This is where the tricky
part comes. The resistor value for R9 is simple: 47K ohms,
half-watt or quarter-watt. But the other resistors are a
different story. In theory, the value for each resistor is double
the previous value. For example, if the first resistor value is
IK ohms, the next value must be 2K and so on. Using this
method, the values are:
Rl = IK ohms
R2 = 2K ohms
R3 = 4K ohms
R4 = 8K ohms
R5= I6K ohms
R6 = 32K ohms
R7 = 64K ohms
R8= I28K ohms
That is fine in theory, but try to find these values in any
store! It is next to impossible, but don't despair; you can get
these values by using more than one resistor for each value.
For instance, a 4K resistor does not exist (unless you want
to custom-order it in quantities of 10,000). But, if you put
two 2K resistors in series with each other, you get 4K. You
see, resistors in series add up in value. A I OK resistor in series
with a 22K resistor gives you 32K. Now, the trick is to find
the right combination of resistors, to match the values above.
Some may require only one or two resistors, but other values
will require as many as four or five resistors to add up to
the right value. It all depends on what value resistors your
dealer carries.
To make matters worse, the precision of the resistors has
to be high. The ideal resistor must have a tolerance of .1
percent. Again, these are expensive and rare. If you are like
me, you have a resistor bin. I went through the bin with an
ohmmeter and measured the values and took the closest
value. If you are not sure how to read the value of a resistor.
Figure 3 shows a resistor color code chart and how to read
it. The first and second colors are the numeric value and the
third is a multiplier. For example, if you have a resistor that
has a color code of red, violet and orange, its value is 27,000
ohms or 27K. Some resistor values are just not made. Here
is a table of resistors that I found and used for my D-to-A
circuit.
Rl = IK
R2 = 2K
R3 = 2K + 2K
R4 = 6.8K+ I.2K
R5= I5K+ IK
R6=22K+ I0K
R7 = 27K + 27K + I0K
R8= I00K + 27K + IK
Again, it is important to have the right values. If you don't
have the right values, keep adding more resistors until you
do; they aren't expensive. Even after you get the right
theoretical values, use a precise ohmmeter to fine-tune these
resistors. Remember, the closer the values you use, the better
the sound it will make. If your resistors are not perfect, at
best, you will get a little harmonic distortion; at worst, you
will get a bad sound.

CoCo 2 to 3 Upgrade
Can a Co Co 2 be upgraded to a
CoCo3?
Basil V. Fine
Abbolsford. British Columbia
ID Since, hardware-wise, the CoCo
pC 3 is a brand new machine that
shares few circuits with the CoCo 2,
such an upgrade would involve replac-
ing the entire printed circuit board. If
Tandy did this and modified the case for
the additional ports (RGB and compos-
ite video outputs), with a nominal
charge for labor, it would probably cost
more than the current price for the
CoCo 3. You may, however, see some
third-party vendors with a CoCo 3
compatible memory upgrade, but as for
the new display options, it would not be
cost-effective.

Model I — CoCo File Transfer
A local business recently gave me a
Model I system, the expansion unit
and disk drives and I. I also have
a 64 A Extended CoCo with cassette. I
have written programs that will run on
either. Is there a method or device that
will enable me to transfer data and
programs between the two?
Brian T. Sprouse
Forest, VA
"D You can transfer ASCII files
■*•/£ between the two using smart
terminal programs with both comput-
ers' RS-232 ports joined with a null-
modem cable. One way to read Model
I tapes into your CoCo is by using the
Magic Box, a cable/ software package
marketed by Spectrum Projects. Brian,
you might also consider using the drives
with your CoCo and abandoning that
"orphan" machine. All you'd need is a
two-drive cable and a disk controller.
Dumping Printer Control Codes

Edward R. Spadoni
Dedham, MA
"D The following program, CHAR-

by poking the values to 255 to screen

Since every one of these values cor-
responds to a character on the screen,
but most printers use some of the codes
below 32 for special effects, a character
translation table must be constructed to
convert these characters' memory
values to their corresponding ASCII
codes, which are understood by Basic's
CHRS function. This table was incorpo-
rated into the DUMP . BflS program which

Small Disks Less Than Great
"] I'm looking for an Amdek 3-inch
Z dual disk drive for my CoCo 2. 1 have
Si written directly to Amdek, hut have
received no response. Are there any
other suppliers of small drives for the
CoCo?
Daniel Moore
Broomall, PA
TJ Regarding the Amdek drives,
■*■ }£ even if I could find you a supplier,
my advice would be don't buy it. If you
really want small drives, get the IBM-
compatible, 720K, 3'/5-inch double-
sided drives, but with these you will also
need one 35- or 40-track, 5 74-inch drive
so that you can use it to transfer soft-
ware from standard media to your
smaller disks. The big hoopla about
these smaller drives is a myth. The
smaller drives do not hold more data
than it is possible to store on the similar
S'/l-inch drives.
The truth is that IBM chose not to
market 80-track, double-sided drives
for the PC. If you want to talk about
storage density, Konica Technology
(Sunnyvale, Calif., 408-773-9551) has a
new 514-inch drive, model K.T-510 with
a formatted storage capacity of 10.9
megabytes. This drive can also read
normal 360K disks. These drives sell for
S400 each in OEM quantities and the
special 5 '/4-inch media for $20 each.

"O The new keys, ALT, CTRL, Fl and
*-jC F2, fill in what were the missing
positions in the keyboard rollover table

and 344, respectively, for a change in
value from 255 to 191.

February I987 THE RAINBOW 181
TAPE UTILITY
A quick cure for I/O Errors
Fast Relief for
Tape-Loading Headaches
By Mark Nelson
rhere are always a few built-in
frustrations that go along with the
use of any computer system. One
of my greatest frustrations with the
CoCo, and I'm sure many of you feel the
same way, is the tape recorder and those
darn I/O Errors. Things get quite a bit
better when you get a disk drive, but
there are still many times when using the
old cassette recorder is the only way to
go. For instance, you may subscribe to
RAINBOW ON TAPE, and some of the
programs you bought before you got a
disk drive won't transfer to disk (some
don't work with the controller plugged
in, anyway).
Let's face it, the tape recorder is an
important part of our computer system
and we'd better learn to live with it.
That's why I wrote Tape Doctor. It
makes it easier to get along with the tape
recorder by changing the CoCo's meth-
od of loading programs and files.
Specifically, it modifies the way I/O
Errors are handled.
The familiar method of handling
these errors is to put the infamous
I'D ERROR message on the screen and
then stop everything. With Tape Doc-
tor, on the other hand, CoCo informs
you of any errors and then continues to
load the tape. This way, all good por-
tions of the program or file are still
loaded when, otherwise, they would be
lost.
Mark Nelson is a computer science
student at Brigham Young University
and author of the Second RAIN BOH'
Adventure Contest winner, Head of the
Beast.
The program listing is quite short, so
even you "two-finger" typists out there
can handle this one. Be sure to save the
program before you run it, because it
erases itself after it runs. Tape Doctor
requires 64K ECB, and yes, it will work
with the disk controller plugged in. I've
used it to help me transfer a few hard-
to-load tapes to disk.
When you have the program on tape
or disk, run it. After a second or two,
the "OK" prompt will appear and you're
ready to load tape programs and files in
the usual way with the BASIC commands
CLOFID, CLOflDM, INPUTtt, etc. When a
tape is loading, you'll see a white block
appear on the screen after a successful
block load (a block is 255 bytes). If an
I/O Error occurred during the last
block, a black block will appear instead,
but the program or file will continue to
be loaded. Obviously, if there are some
black blocks that come up during the
load, there was some faulty data loaded
and it will need to be fixed. If it's a BASIC
program, you may just want to run it
and see where the syntax errors are, fix
them and save the program again.
Machine language programs are a lot
harder to fix unless you're the author,
and even then it's no picnic. But, many
load errors do not have any great effect
on the program's execution. A game
might not give you bonus points be-
tween rounds anymore, or some other
trivial thing might be wrong, but it still
may be fun to play.
If you have a program that uses tape
I/O, you can use Tape Doctor in con-
junction with that software by simply
running Tape Doctor and then your
other software. If you have a file you
can't load with Telewriter-64, you can
use Tape Doctor to help by following
these instructions. CLDRD "TELEG4",
then when the "OK" prompt appears,
type 25 GOTO 100 and press ENTER.
Next, type RUN and press ENTER. Now,
from the Telewriter main menu type B
for BASIC. Load and run the Tape
Doctor. Type EXEC 7720 and press
ENTER to return to Telewriter. You'll be
missing about 3.5K of the text buffer.
To disable Tape Doctor, press the
reset button on the back of the comput-
er, or type POKE &HFFDE,1 and press
ENTER. To re-enable, type POKE
&HFFDF,1 and press ENTER.
I have had pretty good success using
Tape Doctor to load otherwise unload-
able programs and files. I hope you get
as much use out of Tape Doctor as I
have. Now, here are some suggestions
on how to avoid I/O Errors in the first
place.
The Tape Doctor is a last resort
method of loading a bad tape. If a tape
can be loaded without any errors, that's
much preferred. A dirty tape head often
causes I/O Errors. You can buy an
automatic cleaner that you just put in
and "play" like a tape. This is a simple
way of cleaning that is better than
nothing. However, you can do a better
job cleaning by hand. Ask a salesman
at any electronics store to show you how
to clean the heads with cotton swabs
and cleaning solution. A bottle costs
less than two dollars and will last you
many years. The heads shou\o. be
cleaned every two weeks or so. A good
cleaning will take you less than five
minutes, even on the dirtiest machine.
If you still get I/O Errors, try to load
182
THE RAINBOW February 1987
at several different volume settings.
Usually, a slightly lower volume should
be tried. If you're using batteries in your
recorder, buy an inexpensive battery
tester and test them once a month or
more often if you use your computer a
lot. The recorder runs at a slightly
slower speed when the batteries are
weak. If you do save a program or data
onto a tape using weak batteries and
you can't load it after you change
batteries, try putting the old batteries
back into the recorder and loading it
then. If it loads, save it again after
changing to the fresh batteries.
Probably the most common reason
for I/O Errors is misalignment of the
tape head. Aligning the head is a simple
procedure that takes about two minutes
to perform. You will need a small,
jeweler's-type, flat head screwdriver.
First, unplug the recorder from the
computer. Now put the program tape
that's giving you trouble into the re-
corder and press the play button. Lo-
cate the alignment hole, a small hole
through the plastic case, right above the
tape head (NOTE: Some recorders have
no alignment hole and have to be taken
apart to align). Now, insert the screw-
driver into the hold and down into the
alignment screw directly below. Turn
the screw slowly back and forth while
listening to the sound of the program.
You may want to turn the volume down
a little since it sounds terrible. You will
hear the sound get clearer, brighter, and
higher in pilch, and then as you con-
tinue turning, it becomes muffled. The
correct setting is where the sound is the
brightest and highest pitched. Turn the
screw until you're satisfied that you
have the clearest sound possible and
you're finished with the alignment.
One final tip. If you've loaded a
machine language program and you
want to resave it, type CSftVEM
"fit ename" , PEEK ( 8.H1E7 ) *255+PEEI<
(S.H1E8) , PEEK(&H?E)*2S5 + PEEI<
( &H7F ) +255 , PEEK ( &H9D ) *255+PEEK
(&H9E) and then press ENTER. Good
luck in your battle with I/O Errors!

'Uncram' Crowded Tapes
Many people cram several programs on one tape
with very little space between each program. If you
do this, you may want to follow the steps below when
trying to load a program that has been saved later on
the tape. It will prevent a lot of headaches.
1. Count the number of programs saved before the
program you want to load. Good record-keeping will
help in this step.
2. At the beginning of the tape, type M0-
T0R0N:flUDIQ0N and press ENTER.
3. Start counting the number of programs by
listening for silent spots and, at the same time, type
in CLOfiD, but do not press ENTER.
4. At the end of the program just before the
program you are trying to load, press enter.

HAYES ACROSS AMERICA A
feature-enhanced version of the Smart-
modem 2400 became available early in
the fourth quarter of 1986 from Hayes
Microcomputer Products, Inc. The new
features are designed to provide easy
access to modem configuration settings
and to increase stored phone number
capacity. The modem is also now cap-
able of Hayes AutoSync communica-
tions mode. The new features include
the ability to view active and stored
profiles and telephone numbers, storage
for two configuration profiles in EE-
PROM, storage capacity for four phone
numbers and 36-character capacity for
stored phone numbers. Since two uni-
que configuration profiles can be stored
in the modem's EEPROM, users can
save their two most widely used settings
for fast, simple access to selected remote
systems. The new features are imple-
mented using new commands that ex-
pand the Hayes Standard AT command
set. Estimated retail price for the Smart-
modem 2400 is $899. Contact Hayes

Hold Those Variables
By Dan Downard
Rainbow Technical Editor
• Is there a met hod for the CoCo to run
one program, then load a new one while
holding all variables at values set by the
first program (similar to the CHRIN
command of other computers)?
Warren Cole
Nashville. TN
Not while using Disk BASIC, Warren.
You can pass parameters using OS-9,
but you didn't mention if you were using
OS-9. About the only thing 1 can sug-
gest is storing all of your variables in a
short random disk file before running
your new program. Then you can load
the variables back into memory and
continue.

memory range?
Dave Bell
Smithfield, UT
One of the funny things about the
new CoCo 3, Dave, is even though there
is plenty of space for graphics in lower
memory banks, there is no way of
saving or loading the screens. Notice, I
said lower memory banks. When initial-
ized, the normal 64K. occupies from
S70000 to S7FFFF. All other memory
is at $00000 to S6FFFF.
There are several programs appear-
ing on bulletin boards for saving and
loading this information. Various meth-
ods can be used, such as swapping
memory banks using the DAT (Dy-
namic Address Translator), or by use of
a machine language program that will
access the extra memory.
The only documented way to use the
extended memory is by using the LPEEK
and LPOKE functions to copy data from
regular to extended memory. I'm sure
we will run an article on how to save and
load extended memory screens in the
very near future.
Crashed Disk Directories
• / own a 64 K CoCo 2 with Extended
BASIC, disk drive with Disk BASIC I.I.
and a DMP-105 printer. I have a big
problem with "crashed" disk directo-
ries. When I try to write over an existing
program with the same name, I don V get
an AE Error. Disk BASIC writes over the
program, but doesn 7 seem to fix the file
allocation table. Any programs that
appear after this file are lost. When I try
to load these programs I get an FS
Error. Please help.
Randy Adams
Memphis, TN
Randy, I used to have the same
problem. Instead of overwriting a file,
I cured the problem by first killing the
old file before rewriting it. 1 have had
no further problems. If anyone knows
what the exact bug is, please write and
we'll try to explain why this happens.
Color on CM-8

the CM-8 hooked up to the Co Co 3 as
per instructions, most of my programs
run in black and white, not color. Radio
Shack cannot give me a reason, other
than my software is CoCo 2 compatible,
and not for CoCo 3. All the programs
run in color on a TV monitor, but not

The CM-8 is an RGB analog monitor.
Previously, CoCo 2s produced compos-
ite video using an adaptor. You cannot
obtain the same resolution with a com-
posite monitor as you can with an RGB
monitor. In this context, you have
purchased a superior monitor. Ai the
same time, different signals are used for
RGB from the computer to the monitor.
Using the CoCo 2 and a composite
monitor, quite a few of the more recent
graphics programs used artifact colors,
which relied on composite video's color-
burst signal. The CM-8 monitor is not
capable of displaying artifact colors.
A big argument is brewing on
whether the CM-8 is the proper monitor
for the CoCo 3. I think the main con-
tention is that it is not compatible with
a great deal of existing software, as in
your case. Many other RGB monitors
have a composite video mode and will
display artifact colors. As soon as some
of these monitors are submitted for
evaluation, we will give you our opin-
ion. In the meantime, there is nothing
wrong with your CM-8. I'm sure you'll
be satisfied with your CM-8 when more
software is available that uses its capa-
bilities.
By the way, for those readers with
composite monitors, try the following
to get a readable 80-column screen:
WIDTH80 : PALETTES , 25S : PRLETTE0 ,
chips, in sockets, by the way, and
connecting two pads by soldering a

Novice Upgrade
• / have a 16 K Korean CoCo 2 ECB
and I went to Radio Shack lo ask about
having il upgraded to 64K. They told
me it would cost about $70 with parts
and labor, and I would be better off
buying a 64 K CoCo 2 ECB on sale for
$99 (at the time). While thinking this
over, I purchased my first copy of THE
RAINBOW. I noticed several ads for
upgrade kits for about $30. Although
the ads say that all instructions and
parts are included, the problem is that
I have practically no experience in
computer or electronic technology. Is it
feasible for a novice to attempt such an
upgrade on his own? I have gathered
from the ads that one solder joint is
required in upgrading my model, but I
am otherwise in the dark as to how
difficult the procedure would be.

CoCo 3 Drive Compatibility
• Presently I am using an original gray-
case CoCo (E board) with drives and
I and would like to know if these drives
(Part No. 26-3022) and controller (Part
No. 26-3022) are compatible with the
CoCo 3. And, if not, what do I have to
do to make them compatible?
Kenneth Stark
St. Ann, MO
Ken, you need 12 volts for your
particular controller. Experience has
been that it doesn't have to be well
regulated. Find 12 volts in the power
supply of your CoCo 3 and run a jumper
to Pin 2 on the cartridge connector.
Make sure Pin 2 is not grounded. This
may require cutting a trace on the
circuit board.
II you don't want to experiment, buy
a Multi-Pak. It has the 12 volts neces-
sary on the bus for the older disk
controllers.
Disk Controller Necessity
• Is there any way you can use a disk
drive through the f/O port without
having to use the special adapter that
fits into the cartridge port?
Michael S. Novak
Virginia Beach, VA
Michael, the special adapter you are
referring to is the disk controller. It
allows the computer to communicate
with the disk drives, in addition to
containing the Disk BASIC software.
You need a controller to use your disk
drives. 1 wouldn't recommend building
your own.
There are alternate disk controllers
on the market. Alternate disk drives are
also available. The only drawback is
that the software used by non-standard
controllers is also, for the most part,
non-standard. I'm not saying you must
use a standard controller, but be sure
you are aware of the consequences if
you do not. Maybe you could obtain a
non-standard controller with standard
software. It's possible if you order your
BASIC Program Merging
• / have seen numerous procedures for
merging BASIC programs on the CoCo
and they all appear to be essentially the
same. For instance, after loading the
first program, let X1=PEEI<(25), X2=
PEEK (26), X3=PEEI<(27), X4=PEEI< (28).
Providing that X4 is not or I,
P0KE25,X3:P0KE2G,X4-2 and load
the second program. Renumber, if
necessary, so that the line numbers
don't overlap, then P0KE25.X1:
PDKE2G,X2.
More often than not. I find that this
process restores the first program, but
loses the second, both on my32K CoCo
and my 64 K. The results are the same
regardless of whether my disk drive is
connected and wherever in memory
PMODE or PCLEflR commands force the
program to reside.
Harry M. Stern
Miami, FL
You have to rearrange the procedure
you are using, Harry. Renumber the
second program before you load it.
Make sure the line numbers do not
overlap with the first program. Then,
you should be in good shape.
After loading the first program,
memory locations 25 and 26 contain the
beginning address of your program.
Locations 27 and 28 contain the ending
address. You essentially tell the comput-
er to start loading the second program
at the end of the first by P0KE25,
X3:P0KE2G,X4-2. The -2 overwrites
the end of file. Load your second pro-
gram, put the original addresses back in
memory locations 25 and 26, and save
the combined programs.

If You Pay Taxes
You Need Coco- Accountant
All our software is CoCo 3 Compatible
"It's the most useful piece of soft-
ware I own. "
That's what we hear again and
again from folks who buy Coco-Ac-
countant II. This 32/64K single-entry
accounting system for the home and
small business is all you need to
manage your finances and give you
the information you need at tax time.
We wrote the original version for
ourselves two years ago because
we wanted to know three things:
Where did the money come from, where did it go, and
what can we deduct from our taxes?
As it turned out, we liked it better than anything else
on the market, so we decided to sell it. And we've been
improving it ever since.
People say they like it because it's easy to use. Just
spend a few minutes each month entering your data:
checks, cash outlays, credit card expenses or income.
In any order. CoCo-Accountant takes the whole mess
and makes sense out of it. Here's what it does:
♦ Lists and totals entries by month, offsetting in-
come against expenses.
♦ Lists and totals entries by account, for a month or
the whole year.
♦ Lists and totals entries by payee or income
source, for a month or the whole year.
♦ Provides a year-to-date summary
by account.
♦ Prints a spreadsheet showing
activity by account and month for
the whole year (seeing this one is
believing).
♦ Flags deductible expenses.
♦ Flags expenses subject to
sales tax and figures out how much
sales tax you paid!
♦ Lets you define up to 48 ac-
counts (in 64K version).
♦ Takes 900 entries in 64K version, 500 in 32K disk
and 450 in 32K tape.
♦ Sorts entries by date.
♦ Stores your data to tape or disk.
You can use CoCo Accountant as a simple check-
book register or make it into a comprehensive home ac-
counting package. Our customers tell us they use it in
the home, at school, for their clubs, churches and small
businesses. In fact, they use it in ways we never
dreamed of!
CoCo-Accountant II is so easy to use and flexible
that you'll be delighted. So stop shoving all those re-
cords in a shoe box and join the computer age!
The price of Coco-Accountant II is $34.95. Please be
sure to tell us your memory requirements and whether
you want tape or disk.

Island in New York Harbor.
generation database application that
will run on 40 different microcomput-
ers, to CoCo 3 owners soon. Hogg
believes that half of the people who own
Color Computers today will buy a
CoCo 3.
"Then they'll be looking for things to
buy!" Hogg said. "The CoCo 3 can be
the opportunity of a lifetime for you.
Fill a void! Find a need! Fill it! But
remember — more than anything else
— it is very important that you be first
with your application."
Hogg told the three dozen OS-9 Users
Group members present that most
software developers haven't been get-
ting the message that they must use OS-
9 to capture the capabilities of the CoCo
3. He also told the developers that when
they write OS-9 software for the CoCo
3, they will also be writing for the future,
noting that any software written with
6809 OS-9 development tools can easily
be carried into the 68K world.
"Software written in C, BASIC09 or
PASCAL on the Color Computer is
directly compatible with OS-9 68K.,"
Hogg said. "Applications written with
our Sculptor development system can
be carried directly to more than 40
different computers, including most of
the IBM clones."
Hogg was so enthusiastic about the
CoCo 3 and OS-9 Level II opportunities
that we asked him to do an exclusive
interview for "KISSable OS-9" readers.
Some of his answers may surprise you
— especially if you read his now infa-
mous blast at the Color Computer and
OS-9 two years ago.
More Powerful Than a GIMIX III
Dale: How does the CoCo 3 compare
to other 6809 OS-9 computers you have
used?
Frank: It knocks their socks off! The
CoCo 3 with OS-9 Level II and win-
dows is probably one of the most pow-
erful computers around. It is far more
powerful than the GIMIX III I paid
$12,000 for four years ago. And, the
CoCo 3 only costs a few hundred dol-
lars. As a single-user computer, the
CoCo 3 can do just as much work for
you as the GIMIX III. We ran our office
with software developed under Sculptor
on the GIMIX III for several years. Yet,
with a CoCo 3, OS-9 Level II and
windows, we could do a better job -
faster than with the GIMIX III!
Dale: That's hard to believe.
Frank: Yes, I know it seems unbeliev-
able, since the CoCo 3 runs at 1 .8 M Hz
and the gimix hi runs at 2 MHz. But,
the GIMIX III must share time between
several users on different terminals.
Having the CoCo with windows is like
having several terminals on the same
screen.
For example, when we create an
invoice, we need to jump from one
screen to another. With the CoCo 3 we
can use a different window with the flick
of a key! Put in the customer informa-
tion, press a key and instantly we can
enter the invoice. Press the key again
and we can write a letter. If the phone
rings, we press the key again and we're
back in the invoice program. When the
phone call ends, we press it again and
like magic we're back at work with our
letter.
When we installed our office system
in 1982 we paid almost $1,000 for the
terminals alone. Now we can get the
complete CoCo 3 with drives and every-
thing for half that.
Dale: So do you think the CoCo 3 will
be a good business computer?
Frank: It's good for anything and
190
THE RAINBOW February 1987
everything. For business, it's perfect.
For home use, it's perfect too — both
inexpensive and powerful. Of course,
the key to all of the CoCo 3's power
comes from OS-9, its new windows and
the software that runs them.
Dale: What kind of software will
FHL offer for the CoCo 3?
Frank: We plan to release a signifi-
cant number of applications. As you
know, we have had software running on
OS-9 Level II for several years that we
couldn't offer to the CoCo 2 community
because of the lack of available memory.
The new CoCo 3 with OS-9 Level 1 1 and
512K lets all that software work — and
very well, I might add.
The first and most important product
we have for the CoCo 3 is a specially
priced version of Sculptor Plus. CoCo
3 owners will be able to buy it for half
the price of other Level II system
owners.
Dale: That would make the price
about $495. Isn't that too steep for the
CoCo market?
Frank: Well, the very same product
compiled from the same source running
on a VAX minicomputer sells for close
to $15,000! At $495, the CoCo version
is a real bargain. I can't begin to de-
scribe here what Sculptor is or what it
can do. However, to help your readers
discover the power and capabilities of
Sculptor, we will be releasing a demo
disk at a very low price, $5 or so, and
it will be copyable. This means they will
be able to see how it works for them-
selves. We'll also be selling the Sculptor
run-time package for $99. To make that
a bargain, we plan to sell a large number
of application programs written in
Sculptor for $10 to $50. For that price
you'll receive both the source and
object. This means you will be able to
run the application right away. Later, if
you decide to pick up the full Sculptor
package, you'll be able to modify those
programs so they will be a perfect match
for your business.
Dale: Why do you think Sculptor will
be so important to the CoCo 3 owner?
Frank: It is the most powerful devel-
opment system I have ever seen on any
computer. There are versions of Sculp-
tor running on more than 40 different
computers and the programs written in
it are compatible between the different
machines.
You could develop Sculptor pro-
grams on your $200 CoCo 3 at home,
carry the program to a million dollar
VAX at work and run it without any
modifications! No other development
system can do that. Plus, the develop-
ment time is incredibly short. You can
develop applications using Sculptor in
about one tenth the time it would take
with most other languages.
time you can press one key and instantly
move to another window! You can
bounce back and forth from one to the
other at will, doing whatever is neces-
sary along the way.
"Many people believe that
OS-9 will never be popular
because it is not
compatible with the IBM
PC. We don't agree!"
Dale: What kind of applications can
you develop with Sculptor!
Frank: Most people use Sculptor
when they need an application that can
access a large amount of data from
several different databases very quickly.
We have packages written in Sculptor
that can manage a dental office, a real
estate office or manage property. We use
other Sculptor programs to maintain
general ledgers, record accounts receiv-
ables, and manage accounts payable.
We also have clients using Sculptor for
church management and mailing list
management. All of these programs run
on Sculptor and are very fast. They can
access over 22 million records. And, any
one of these records can be retrieved
from a hard disk in less than a second.
Dale: How will Sculptor on the CoCo
3 differ from Sculptor on the GIMIX III?
Frank: Actually, Sculptor will appear
to run faster on the CoCo 3 because of
the windows. Keep in mind that the
GIMIX III runs at almost the same clock
speed as the CoCo 3 but doesn't have
windows. To match the CoCo 3, the
GIMIX would need to have several ter-
minals hooked to it.
Dale: How will you use the CoCo 3
windows with Sculptor'!
Frank: Imagine you run a mail order
business and need to do a lot of typing
and other standard office chores. For
starters, you will want a hard disk to
keep your business records. Even
though you can keep many records on
a floppy disk, business people need to
have enough storage on line to hold all
of their information and they need to
get at it fast. With a hard disk and
Sculptor you have this ability.
When you first bring the system up,
you may start an invoice program in the
first window. Then, open another win-
dow and start the word processor. Then,
you may create another window to run
a few maintenance programs. At any
Dale: Why is it important that Sculp-
tor is compatible with other computers?
Frank: Look at all the people who
have written their software in BASIC. If
they need to switch to another comput-
er, like an IBM PC, they will have a
major rewrite on their hands. With
Sculptor running under 40 different
computers — and the list is growing
daily — that problem just doesn't exist.
No businessman knows what his com-
puter needs will be three years from now
and Sculptor gives him the flexibility to
move his applications to another ma-
chine at any time. Of course, it is the
logical choice for developers for the
same reason.
Dale: What do you think of the future
of the CoCo 3?
Frank: It will be long and good. Most
people don't realize the CoCo 3's poten-
tial at this time and it will take several
years before it starts to reach its limit.
The future looks very, very good in-
deed.
Dale: How important is OS-9 to the
CoCo 3's success?
Frank: Vital! Absolutely vital! With-
out OS-9 you lose the windows, the
multitasking and the programs like
Sculptor. BASIC is only good for small
jobs and has a very limited future. OS-
9 is definitely the only way to fly.
Dale: What else will FHL be selling
for the CoCo 3?
Frank: We are working on a Word-
Star clone for both OS-9/ 6809 and OS-
9/68000. Because WordStar is so pop-
ular and has so many books and train-
ing programs available to support it, we
think it will make a nice product.
Many people believe that OS-9 will
never be popular because it is not
compatible with the IBM PC. We don't
agree! Instead of trying to run IBM
software, we are going to market OS-
9 software that operates like IBM
software. However, because of OS-9's
February 1987 THE RAINBOW 191
superiority, the program will do many
things that IBM versions will never be
able to do.
Dale: How do you rate the CoCo 3
against the PC?
Frank: The CoCo 3 runs circles
around the IBM PC. But, it is unfair to
compare a silk purse to a sow's ear. The
CoCo 3, with its windows, OS-9 Level
II, and our QT CoCo hard disk — if you
will — is powerful enough to run a good
sized business.
"The thing that
excites me about
Multi-View is the
fact that it creates
conventions for
data interchange
that developers
would be fools not
to use. 9 '
Dale: What is the QT CoCo?
Frank: It is a hard disk and floppy
disk system for the CoCo 3 or CoCo 2
that is based on our QT.
Dale: I don't get it, why the QT?
Frank: The QT without the computer
board is probably the smallest disk
drive enclosure with a solid power
supply and provisions for both a hard
disk and a floppy you can buy. It can
also be upgraded to a full 68000-based
QT computer system at any time.
Dale: What do you get when you buy
a QT CoCo?
Frank: You get everything that is in
a QT except the computer board. You
get the case, a double-sided floppy
drive, a 20-megabyte hard drive, a
controller, a power supply, cables, etc.
These are the exact same parts that are
used in the QT. They go through the
same testing and quality control. We
just leave out the parts that are only
needed for the QT This means nothing
is wasted later if you want to upgrade
to the QT. The system is fan cooled and
has a power supply much more power-
ful than even the QT needs. In fact, the
power supply alone costs more than a
CoCo 2 costs today.
Dale: Why would you want to buy a
QT CoCo instead of another hard disk
drive?
Frank: There are several reasons.
First, there's the size. The QT CoCo is
very small — less than half a cubic foot.
Besides the CoCo 3, it's all you'll need
on the desktop. One of the things that
has always bothered me about the
CoCo is all the little boxes and wires
that you need to make a complete
system. With the QT CoCo, you reduce
the number of boxes and that creates a
more professional appearance and
takes up less desk space. Another rea-
son is reliability — the QT has been out
for two years now and it has proven to
be a very reliable computer. Using this
same technology in a hard disk system
brings that reliability to the CoCo. Of
course, the QT CoCo is the only hard
disk system that can be upgraded to a
full 68000-based computer later and
that should be important to you if you
think you will ever want to move up to
a bigger system.
Dale: What do you lose when you
upgrade to a QT?
Frank: I didn't mean to imply that
everything is used. Only the parts in the
QTcase itself can be used. You also need
a controller for the hard drive and a
floppy disk controller if you don't
already have one. We are selling the
Disto controller and SASI interface
because they both fit in a case the size
of a Radio Shack disk controller. This
means that you don't need to install a
multipack to use the system. The Disto
hard disk interface also gives you a
serial interface that you can use with a
printer or terminal at full speed without
losing characters. All in all, Tony has
built a great system. If you upgrade later
you can still use the Disto floppy con-
troller. You will only lose the use of the
SASI interface card.
Dale: If you do upgrade to a QT, how
do you convert the files on the hard disk
to the QT?
Frank: You don't need to! The 68000
OS-9 file format is the same as the 6809,
so the QT can read the hard disk with-
out any reformatting.
Dale: What does it cost?
Frank: The price isn't firm yet. But,
it will be less than the price Tandy
charges for their 1 5-Meg hard disk. You
will be able to get a floppy and a 20-Meg
hard disk, plus controller, plus the
potential for upgrade to a QT later for
less money than you would pay Tandy
for their I5-Meg hard disk!
Dale: How else will you be support-
ing the CoCo 3?
Frank: On the hardware side, we are
already selling 5I2K upgrade boards,
disk controllers and complete disk drive
systems. On the software side we will be
marketing FBU, a high performance
hard disk backup utility; QCom, a
communication program that uses the
Xmodem protocol and two additional
utilities, ULD and DLD, which let you
upload and download files quickly.
Dale: What is FBW.
Frank: FBU is designed to back up
a hard disk to a number of floppy disks.
It is optimized for speed and uses a
minimum number of floppies because it
compresses your files before it saves
them. FBU comes with a utility named
FRS which restores your files to the
hard disk, creates directories, and sets
all the attributes, owner IDs and dates.
Dale: What about your communica-
tions programs?
Frank: QCom lets you send or receive
straight ASCII text files. It also lets you
upload or download any file using the
Xmodem protocol or simply chat on
line. DLD and ULD give you a way to
transfer programs to or from your
CoCo 3 when you are communicating
with another computer. They also use
the Xmodem protocol.
My First Look at Level II
"OS-9 Level 11 has to be the software
bargain of the decade," said Tandy's
Mark Siegel as Bruce Warner and I
followed him into a private room at the
Hyatt in Princeton. "Where else can you
buy all this power for $79.95?"
After seeing Level II, Warner and I
both decided that Siegel's remark had
to be the biggest understatement of the
year. We only got to watch the CoCo 3's
new operating system perform for
about 30 minutes, but we liked what we
saw.
Siegel created a few windows with
short command lines from the OS-9
prompt. After he had filled the screen
with windows he started a new shell in
the largest window. The command
sequence looked something like this:
0S9: mantype m
0S9: iniz u?
059: ex shell i=/u7
At this point, approximately 48K of
memory remained free in the 128K
machine we were using. Siegel re-
marked that he had created up to 14
windows with shells and applications
running in them in a 512K machine.
While we watched, Siegel started
shells in each of the three windows he
had opened and ran a different utility
in each — concurrently. He toggled

between the windows by striking a
single key on the new CoCo 3 keyboard.
We were impressed.
Siegel told us that with the new Level
II OS-9 software, contiguous memory
would not be needed for programs.
However, it is needed for windows. We
also learned that OS-9 Level II looks for
a file named Autoex and that we would
probably be running out of memory for
process descriptors before we run out of
memory for our programs. Yet, he said
at one time he had run 28 individual
processes before he ran out of memory.
We also learned that we would no
longer be able to load drivers for new
devices and then run them. We would
need to use 0S9Gen to put them in a new
059Boot file. Level II OS-9 has a mouse
driver built in. But, if you don't like
mice, you can use the keyboard as a
pseudo-mouse. A special joystick
adapter that plugs into the joystick port
and sells for $9.95 lets you point your
mouse at any one of the 640 individual
pixels in a line when you are running
your CoCo 3 at its highest resolution.
Even though the OS-9 Debug utility
will no longer come with the basic OS-
9 release, you will still be able to patch
modules in memory using a special
utility named ModPatch. It will update
the CRC for you automatically and
eliminate the need for the separate
verify step. Debug will now be part of
the development package. By the way,
you'll still be able to do plenty of
reading when you move up to OS-9
Level II. The new manuals promise to
be about 700 pages long — would you
believe they started out at 900 pages?
One of the most exciting things about
OS-9 Level II and the CoCo 3 is the part
we didn't get to see. Siegel didn't get to
show us Multi-View at Princeton be-
cause there weren't any 512K machines
around to use for a demo.
Multi-View is an enhanced window-
ing environment designed specifically
for the CoCo 3. It gives a common,
graphics-based environment to run
your application programs in. Title
bars, menu bars, pull-down menus and
dialog are all built into the system. This
graphics shell lets you select picture-
oriented commands (most people call
them icons) to run your programs. A
number of desktop utilities, or tools, are
a keystroke away. An alarm clock,
calculator, calendar/ memo book, con-
trol panel and clipboard support are all
built in. Two other accessories let you
configure your printer or call for help
at any time.
The thing that excites me about
Multi-View is the fact that it creates
conventions for data interchange that
developers would be fools not to use.
This means that the OS-9 programs of
the future will have a central look or feel
because they will use the same method-
ology. You, the end user, will be the real
victor because you will only need to
learn how to save data with an OS-9
application one time. Why? Because, all
OS-9 software will carry out similar
functions in a similar way. In a nutshell,
you will save your data in your spread-
sheet the same way you save your data
in your word processor, etc. Other
standard operations will also be done
the same way across the spectrum of
application software.
Yet, Microware and Tandy have
designed the OS-9 Level II system on
the CoCo 3 so that they can be flexible
in the future. If the industry standard
"user interface" changes in a few years,
they will be able to write a new one. The
internals of the operating system will

slay the same and won't need to be
changed.
The Race Is On!
The race has already started among
CoCo 3 third-party hardware vendors.
Three vendors have announced 512K
upgrade boards for the CoCo 3.
Bob Rosen at Spectrum Projects is
selling his for SI 39.95. It uses 16 prime
256K DRAMs. You can buy it without
the RAM chips for $99.95.
Tony DiStefano, who designs hard-
ware for CRC, Inc., has released his
5 1 2K board also. It sells for $ 1 29.95.
And finally, Frank Hogg at FHL is
selling the PBJ 512K upgrade for the
CoCo 3 at $129.95. FHL sells the bare
PBJ board without the memory chips
for $49.95.
Another Utilipak
Steve Goldberg continues to improve
his Utilipak software. Now, new
customers can buy Utilipak, Sr. for $20.
What a bargain! For the price you get
40 utilities. And Goldberg hasn't forgot-
ten Utilipak veterans. They can upgrade
their package by sending a blank disk,
a postage paid mailer and $7 to Gold-
berg at 695 Plainview Road, Bethpage,
NY 1 1714.
Goldberg no longer sends a printed
manual with his bargain basement
utilities. Rather, he puts it on your disk
and gives you a procedure file which will
print it automatically. Utilipak, Sr. is a
combination of Utilipak and Utilipak
Too. It supercedes both by replacing a
number of existing programs, adding
better error handling and enhancements
to others. Many of the original utilities
run much faster. Especially notable are
improvements to Grep, Pk, Unpk,
Crypt, Head and Tail.
Skala Discovered
Back in July we mentioned some
256K RAM disk drivers for The
Banker. They were written by Dennis
Skala and are available in the OS-9
database on rainbow's Color Comput-
er S1G on Delphi. Since then we have
received several dozen requests for
Dennis' address. Here it is: 5423 West
Sebago Drive, Fairview, PA 16415. Be
sure to say thanks!
CoCo 3 Programs Appearing Online
CoCo 3 OS-9 programs are starting
to show up in the online databases. For
example in the OS-9 database on our
Delphi CoCo SIG, you can now find a
CoCo 3 driver for your Word-Pak II.
It was written by an OS-9 user named
Connolly.
Connolly has also contributed a
number of other utilities that may cause
you to join the fun on the CoCo SIG.
Included in the latest index compiled by
OS-9 database manager Dale Lear are
a file directory utility, an archive/
restore utility set and Make, a UNIX-
like development utility. He has also
uploaded a Make script file that shows
you how to patch a module. More than
three dozen files have appeared since we
first reported the increased activity last
month. Join the fun.
On the CompuServe OS-9 SIG you
can also find a number of new CoCo 3
programs in the database. The two most
important this month are CO380, an 80-
by-24 screen driver. It runs under OS-
9 Level I, Version 2.00.00 and was
written by Mike Dziedzic, 134 Drift-
wood Drive, Grand Island, NY 14072.

released. It also supports the OPak Hi-
Res control codes so that you can run
some of the older software, such as
DynaStar, on your CoCo 2.
Another interesting CoCo 3 file is
CC3Fix, a utility that lets you create an
OS-9 Level I, Version 1 .00.00 or Version
1. 01. 00 disk that will run on the CoCo
3. You boot the system normally, run
CC3/ix and then do a cobbler to a
freshly formatted blank disk. This new
system disk will boot directly on the
CoCo 3 without the memory conflicts
that previously caused Version 1.00.00
and Version 1.01.00 of OS-9 to crash. It
was written by Kent D. Meyers.
Unload, SysGo for Version 2.00.00
and a BASIC09 Procedure
Mark Roseman of 736 Queenston
Street, Winnipeg, Manitoba, Canada,
sent us a note with an assembly lan-
guage program that you can use with
BASIC09 to find the size of a file, or your
current position within a file — a
BASIC09 equivalent of LOF and LDC in
Microsoft BASIC. To do the job, you use
an OS-9 ISGetstt call. To call his
routines, use a BASiow statement like
this.
run f i lesize(pa th,hi , lo)
fs := hi » S553G + lo
Path, hi and lo are all integer var-
iables, or parameters, and fs is a real
variable which holds the file size. A call
to fileptr would be written in a
similar fashion. For his program, see
listings 1, 2 and 3.
This demo program asks you for a
filename, then prints the size of your file
and tells you where the file pointer is
currently pointing. In the example it
will still be pointing lo the beginning of
the file, or zero.
Both SysGo for Version 2.00.00 and
UnLoad were contributed by Fred
Sawtelle of 3103 Montgomery Road,
Huntsville, TX 77340. Sawtelle is the
author of several other utilities we
published during 1986.
By the time I sit down to work on the
March edition, I should have had some
hands-on experience with OS-9 Level II
on the new CoCo 3. We'll cross our
fingers! Till then, enjoy! □

THE ORIGINAL
Simply stated. Telewriter is the most powerful
word processor you can buy for the TRS-80
Color Computer. The original Telewriter has
received rave reviews in every major Color
Computer and TRS-80 magazine, as well as
enthusiastic praise from thousands of satisfied
owners. And rightly so.
The standard Color Computer display of 32
characters by 16 lines without lower case is
simply inadequate for serious word processing.
The checkerboard letters and tiny lines give you
no feel for how your writing looks or reads.
Telewriter gives the Color Computer a 5 1
column by 24 line screen display with true
lower case characters. So a Telewriter screen
looks like a printed page, with a good chunk of
text on screen at one time. In fact, more on
screen text than you'd get with Apple II, Atari,
TI, Vic or TRS-80 Model III.
On top of that, the sophisticated Telewriter
full-screen editor is so simple to use, it makes
writing fun. With single-letter mnemonic
commands, and menu-driven I/O and
formatting, Telewriter surpasses all others for
user friendliness and pure power.
Telewriter's chain printing feature means that
the size of your text is never limited by the
amount of memory you have, and Telewriter's
advanced cassette handler gives you a powerful
word processor without the major additional
cost of a disk.
...one of the best programs for the Color
Computer I have seen...
— Color Computer News, Jan. 1982
TELEWRITER-64
But now we've added more power to
7e\cwriter. Not just bells and whistles, but
major features that give you total control over
your writing. We call this new supercharged
version Telewriter-64. For two reasons.
64K COMPATIBLE
Telewriter -54 runs fully in any Color Computer
— 16K, 32K, or 64K, with or without Extended
Basic, with disk or cassette or both. It
automatically configures itself to take optimum
advantage of all available memory. That means
that when you upgrade your memory, the
Telewriter-64 text buffer grows accordingly. In
a 64K cassette based system, for example, you
get about 40K of memory to store text. So you
don't need disk or FLEX to put all your 64K
to work immediately.
64 COLUMNS (AND 85!)
Besides the original 51 column screen,
Telewriter-64 now gives you 2 additional high-
density displays: 64 x 24 and 85 x 24!! Both
high density modes provide all the standard
Telewriter editing capabilities, and you can
switch instantly to any of the 3 formats with a
single control key command.
The 51 x 24 display is clear and crisp on the
screen. The two high density modes are more
crowded and less easily readable, but they arc
perfect for showing you the exact layout of
your printed page, all on the screen at one
time. Compare this with cumbersome
"windows" that show you only fragments at a
lime and don't even allow editing.
RIGHT JUSTIFICATION &
HYPHENATION
One outstanding advantage of the full-width
screen display is that you can now set the
screen width to match the width of your
printed page, so that "what you sec is what
you gel." This makes exacl alignment of
columns possible and it makes hyphenation
simple.
Since short lines are the reason for the large
spaces often found in standard right justified
text, and since hyphenation is the most
effective way to eliminate short lines,
Telewriter-64 can now promise you some of the
best looking right justification you can get on
the Color Computer.
FEATURES & SPECIFICATIONS:
Printing and formatting: Drives any primer
(LPVII/VUI, DMP-IOO/200, Epson, Okidata,
Centronics, NEC, C. Itoh, Smith-Corona,
Tcrminct, etc).
Embedded control codes give full dynamic access to
intelligent printer fcaiures like: underlining,
subscript, superscript, variable font and type size, dot-
graphics, etc.
Dynamic (embedded) format controls for: top,
bottom, and left margins; line length, lines per page,
line spacing, new page, change page numbering,
conditional new page, enable/disable justification.
Menu-driven control of these parameters, as well as:
pause at page bottom, page numbering, baud rate (so
you can run your printer at top speed), and Epson
font. "Typewriter" feature sends typed lines directly
to your printer, and Direct mode sends control codes
right from the keyboard. Special Epson driver
simplifies use with MX-80.
Supports single and multi-line headers and automatic
centering. Print or save all or any section of the text
buffer. Chain print any number of files from cassette
or disk.
File and I/O Features: ASCII rormat files —
create and edit BASIC, Assembly, Pascal, and C
programs, Smart Terminal files (for uploading or
downloading), even text files from other word
processors. Compatible with spelling checkers (like
Spell 'n Fix).
Cassette verify command for su*e saves. Cassette auto-
retry means you type a load command only once no
matter where you are in the tape.
Read in, save, partial save, and append files with disk
and/or cassette. For disk: print directory with free
space to screen or printer, kill and rename files, set
default drive. Easily customized to the number of
drives in the system.
Editing features: Fast, full-screen editor with
wordwrap, block copy, block move, block delete, line
delete, global search and replace (or delete), wild card
search, fast auto-repeal cursor, fast scrolling, cursor
up, down, right, left, begin line, end line, top of text.

text, tabs, choice of buff or green background,
complete error protection, line counter, word counter,
space left, current file name, default drive in effect,
set line length on screen.
Insert or delete text anywhere on the screen without
changing "modes." This fast "free-form" editor
provides maximum case of use. Everything you do
appears immediately on the screen in front of you.
Commands require only a single key or a single key
plus CLEAR.

CoCo3
BITS AND BYTES OF BASIC
The CoCo 3 Color Palette
From a BASIC Program
By Richard A. White
Rainbow Contributing Editor
With 64 colors to choose from,
things can get confusing fast.
The Sample 23 program in
the manual displays all available colors,
eight at a time. This will get you started,
but the next question is, how does one
color look next to a similar one on a
different screen? The answer is to write
a program in BASIC. This kills two birds
with one stone. It meets my needs and
also serves as a tutorial on how the
palette works and how some of the new
BASIC commands that deal with high
resolution screens work.
We will work in the 16-color, 320-by-
192 graphics mode. The idea is to draw
16 boxes in buff on a black background.
Each box is to be filled, in order, from
the palette so that each color in the
palette is shown. Since we can print
characters to this screen, we will
number each box with the palette slot
it is referencing and print the number of
the color displayed in each slot.
The program starts with a little
housekeeping. The DIM CC( 15) in Line
5 establishes a numeric array that will
keep the number of the color in each
palette slot. The array numbers relate
directly to the palette slot numbers.
POKE G5497,0 sets the microprocessor
speed to 1.8 MHz. POKE G549G,0 will
reset the clock to .9 MHz.
There are two different default
palette color selections based on the fact
that televisions and composite video
monitors display colors differently from
the CM-8 Analog RGB Color Monitor.
Line 8 prints the question about an
RGB monitor and the INKEYS state-
Richarcl White lives in Fairfield. Ohio,
has a long background with microcom-
puters and specializes in BASIC pro-
gramming. With Don Dollberg, he is
the coauthor of the TIMS database
management program.
ment in Line 10 looks for a Y or N
answer. Note that Line 10 is written so
that only a Y or an N are accepted and
that any other letter, including all
lowercase entries, sends the program
back to the start of Line 10.
Users with anything other than a
CM-8 monitor should enter an N. When
N is pressed, the program does a RE-
STORE to assure that the data pointer is
reset and then enters a F0R-T0-NEXT
loop to read A 16 times. The data in lines
2000 and 2010 are the default color
numbers for the RGB monitor in Line
2000 and for TV or composite video in
Line 2010. When READ A has been done
16 times, the data pointer is positioned
to the first data item in Line 2010. Then
the PALETTE CMP command sets the
palette to the composite video default.
If Y is chosen, the program restores
the data pointer and does a PALETTE
RGB, which loads the RGB default
palette colors.
Well, this almost works. There is a
small bug. It is not apparent if one
simply switches from the CMP to the
RGB color set, since Slot 15 is filled
with Color 38 in both instances. If Slot
15 is loaded with some other color, the
commands PALETTE RGB and PALETTE
CMP do not reset Slot 1 5 to Color 38, but
leave it unchanged. Once you have this
program running, change the color in
Slot 15, break and rerun the program.
You will see all the default colors except
in Slot 15 which remains the color you
previously set.
If, however, you use the reset button
to break the program, you will find
Color 38 in Slot 15 when you rerun the
program. The reset button resets the
machine to the CMP default colors
including Slot 15, which will contain
Color 38.
Add 20 HC0LDR4,B:HSCREEN2.
An HSCREEN command is used to
both clear and display a CoCo 3 high
resolution graphics screen. You have
five choices:
HSCREEN0
HSCREEN1
HSCREEN2
HSCREEN3
HSCREEN4
Low resolution
320 X 192, 4-color
320 X 192, 16-color
640 X 192, 2-color
640 X 192, 4-color
The HCOLOR C1,C2 command sets a
foreground color, CI, and a back-
ground color, C2. Color numbers range
from to 15 and refer directly to the
palette slot numbers. The default uses
Slot I for the foreground and Slot for
the background. I felt the colors would
show up better against a black back-
ground (Slot 8), and used buff for the
foreground. Slot 4. So, in Line 20,
HCOLOR 4,B picks my choices and
HSCREEN2 puts us in the graphics envi-
ronment. Note that these color choices
hold only as long as buff and black
remain selected for slots 4 and 8.
HSCREEN0 appears to be the way for
the program to break out of graphics to
get back to a text screen. Since HSCREEN
clears the screen with the then-current
background color each time it is used,
there is no way for BASIC to draw a
hidden graphic and then display it like
you can using PMODE and SCREEN com-
mands in the CoCo 2 mode. The CoCo
3 way to do this is to set all the palette
slots to the same number, issue an
HSCREEN command and then follow
with the code to generate the graphics.
Use HCOLOR C1,C2 to set new fore-
ground and background colors for
PSET and RESET when used with HLINE,
HPUT, HSET and HRESET. Next, use FOR
X = 1 to 15 : PALETTE X,C2 : NEXT
to set all palette slots to the same co\or.
Now, where a color number is used in
a command, use any palette number in
the to 15 range. Since all the colors
200
THE RAINBOW February 1987
in the palette are the same, the screen
will remain clear. When it comes time
to display the graphic, load the desired
color numbers into their palette slots
and the picture instantly appears.
A variation on this strategy is to load
colors into the palette in such a way as
to make the picture grow and change on
the screen. The dragon sequence in
Radio Shack's CoCo 3 demo is an
outstanding example of this technique,
where the room comes slowly into being
and wall colors lighten as torches along
the walls are lighted. The torch light is
made to flicker and dance just by chang-
ing palette slot color assignments. The
changes are subtle, increasing their
effectiveness. Although the demo is a
machine language program, the types of
changes used in this sequence are slow
enough that basic will easily handle
them. This sequence also illustrates the
fact that the 64-color selection and the
16 colors available at a time will meet
all but the most exacting needs. Scenes
tend to be bright or drab or pastel, but
not all these things at the same time.
One color set works well in a dungeon
while an entirely separate set is needed
for an outdoor scene.
Line 30 uses HLINE to draw horizon-
tal lines in the upper, center and lower
parts of the screen. In the first paren-
theses is the X,Y location of the start of
the line. The 0,0 position is the top-left
corner of the screen. The X dimension
is horizontal and ranges from to 319,
increasing to the right. The Y dimension
is vertical and ranges from to 191
increasing from top to bottom. PSET
draws in the pre-selected foreground
color slot. RESET draws in the pre-
selected background slot. A slot
number (0 to 15) may be used in place
of PSET or RESET.
HLINE also may be used to draw a
box by using 'B' parameter. The syntax
is HLINE (xl,yl)-(x2,y2),PSET,B.
You can also fill the box with the color
of the outline using HLINE (xl.yl)-
(x2,y2),PSET,BF. Of course, all of
this is the same as CoCo 2 Extended
BASIC.
Line 40 draws vertical lines to gener-
ate 16 boxes. Line 50 first paints the top
row of boxes with colors from slots
to 7 and then does the same to the
bottom boxes using colors 8 to 15. This
is accomplished using HPAINT (x,y),
C1,C2. Of course X,Y defines the pixel
where painting is to start. The color to
use is put into the CI location. Color C2
is border color where painting is to stop.
Remember colors C 1 and C2 really refer
to palette slots. At the same time the
color number for each color is read into
the array CC(X).
Cheers are in order. CoCo 3 Ex-
tended BASIC lets us print text anywhere
on a graphics screen. In the 320-by-192
mode the 40-column character set is
used while the 80-column set is used in
the640-by-I92 mode.
Enough celebration — how does it
work? HPR I NT ( X , Y ) prints text starting
at X column and Y row. Note that it uses
columns and rows and not pixel posi-
tions. This is consistent with the way the
LOCATE X,Y command works when
moving the cursor on a text screen. In
Line 60, HPRINT(8, 0) , "CURRENT
PALETTE COLORS" prints the string
starting at Column 8 in Row 1.
The string may be defined in an
HPR INT statement or be held in a string
variable. In Line 70, text is assigned to
string variables ST$ and 5BS, which are
then printed by the HPRINT statements
in Line 80. The function here is to print
50 through 57 above the top row of
boxes and 58 through S15 beneath the
bottom row to identify palette slot
numbers.

February 1987 THE RAINBOW 201
The next task is to print the color
number directly above or below the slot
number. Since we are starting with a
default color set, I was able to put the
color numbers for the default colors
into DATA statements, which were sub-
sequently loaded into the numeric
array, CC(X). To generate a string
containing a color number, the expres-
sion CCS = "C"+STR$(CC(X)) is used
and the result will have the form "C ZZ"
since STRS( ) adds a leading space
when converting positive numbers. The
top row of color numbers is printed
using the FDR-TO-NEXT loop in Line 90
while the bottom colors are printed in
Row 22 using the code in Line 100.
Since the loop in Line 90 starts with 0,
the "C ZZ" strings will start in Column
and be printed at five column spaces.
In Line 100, the FDR-TO-NEXT index
starts at 8, so 8 must be subtracted from
X in the HPRINT statement. This is why
there are separate lines to print the top
and bottom rows.
"(.heers ore in order.
CoCo 3 Extended
BASIC lets os print
le.xi anywhere on o
graphics screen. "
The high resolution graphics use
HGET and HPUT in the same way GET and
PUT are used in CoCo 2 Extended
BASIC. A nearly 8K memory space is
allocated in the 64K memory block that
contains the high resolution screen
memory. HBUFF buffer, size allocates a
portion of the 8K block to a buffer
where buffer is a number, and size is the
number of bytes. Determining the
number of bytes required is the confus-
ing part.
The manual approaches the question
by defining the number of dots or pixels
a byte of memory can define. Read and
digest that approach, then read the
following where I will try a bit different
tack.
Let's start with bits. A bit may be on
or off. This is a two-state system. In a
two-color graphics mode, the fore-
ground and background colors are
preset. It is then sufficient to know that
a dot should be on or off. If the dot is
to be on, it is set to the foreground color.
If it is lo be off, it is set to the back-
ground color. HSCREEN 1 sets a two-
color, 320-bv-192 mode where the de-
fault foreground is set for Slot I and the
default background is set to Slot 0. You
can change this with HCOLDR C1,C2
discussed earlier. HSCREEN 2 used in the
program is a 16-color mode that re-
quires four bits to relate any of the 16
palette locations to the dot.
Now let's look at the HGET statement
in Line 190 which says HGET(0,0)-
(20, 8), 2. The 0,0 to 20,8 area en-
compasses eight rows of 20 dots each.
In a two-color mode where each dot
needs only one byte of data, each row
of dots would need only two and a half
bytes. However, since it is necessary to
move even bytes, this rounds up to three
bytes. But, the row might not start on
a byte boundary. It might start at the
end of one byte, bridge two other bytes
and end in a fourth byte. So in a worst-
case situation, four bytes might be
required. With eight rows, a simple
multiplication of 4 times 8 yields 32
bytes. The manual says add I to the row
number and then do the multiplication
and we get 36 bytes. The manual further
states the size is 1 less than the calcu-
lated size, so the buffer allocation
statement would be HBUFF 1,35.
The method in the manual tries to
sort out the cases where the row of dots
only bridges three bytes and allows a
reduced buffer allocation.
Multiple color modes need more of
each byte to store their color informa-
tion. A four-color mode needs to store
four states, which can be done with two
bits, so each byte defines four dots. The
16-color, 320-by-1 92 mode needs to
store 16 states, which requires four bits.
Each byte only defines two dots.
In the HSCREEN 2, 16-color mode, at
least 10 bytes are needed to save a row
of 20 dots. If the row had run from I
to 2 1 , 11 bytes would actually have been
involved. Following the book, eight
rows plus one yields a multiplier of 9
and a block size of 99. In Line 190, I
properly used a size of 99 minus 1, or
98. Unfortunately, there is evidence that
buffer sizes calculated by the book do
not always work. A friend defined three
98-byte buffers in three successive lines
of code. His machine hung up. He
changed the first line to HBUFF 1 , 99 and
the program ran, even though the fol-
lowing two lines used HBUFF 2,98 and
HBUFF 3,98, and the HPUT statement
was identical in all three cases.
I originally made a mistake and
defined the buffer in Line 1 10 as HBUFF
2,807 when the correct code is HBUFF
2,908 and the program ran fine on my
machine. I have no assurance that it will
run on someone else's machine. It seems
irrational, but that's what the data I
have now says. How about some of you
CoCo 3 owners experimenting with
this? Write if you find enlightenment.
Obviously, things are flaky with
HBUFF. If you have trouble, first make
sure you have properly calculated the
buffer size. If you have, add 1 to that
size. In fact, if you share your programs
perhaps the prudent course is not to
subtract that last 1 from the buffer size.
Two error modes have been docu-
mented at this time. First, the machine
may hang up and require use of the reset
switch. If the buffer size given is too
small, an FC Error results, providing
BASIC chooses not to accept the defini-
tion — and basic seems to be doing
some funny choosing these days.
Lines 200 through 215 simply use
INKEYS to get the number of the slot
where you want to change a color. The
single-digit or two-digit number is kept
in variable 5L$ as a string. VAL ( SL$ ) is
used to put that number into a numeric
variable SL, which is tested to assure
that it is within the to 15 range.
When we did the HGET to fill Buffer
1, we got a buffer full of background
color referencing Slot 8 in the palette.
Now we use HPUT (0, 184 )-(200,
192 ) , 1 , PSET to blank the slot number
question-and-answer text. When you
HPRINT to a graphic, BASIC draws each
character using the foreground color
active at the time. Only those dots
actually defining the character are
written. HPRINTing a string of spaces
changes no dots which may already be
on the screen. So, it is necessary to
actually HPUT background color over
characters to erase them. Next, we
HPRINT the slot number chosen and ask
for a color number. It is held in CCS and
CC and is tested to assure it is within the
to 63 range.
In Line 250 the color in Palette Slot
SL is changed to CC. The rest of the line
is housekeeping to erase the text on the
bottom line of the screen. Lines 255 and
260 are used to erase the old color
number and write the new one at the
changed slot display. The program then
returns to get another change.
1000 GOTO 1000 is a programming
aid. It locked up the program so I could
see the results of each piece of code as
1 wrote it. Of course, pressing break
returns to the text screen for changes or
more programming. If you type in the
program, put Line 1000 in first and then
simply type RUN from time to time to see
if things are working right.
At this point, I am very favorably
impressed with the CoCo 3, its graphics

OS-9
TUTORIAL
Pipes and Filters for the Masses
By Bruce N. Warner
The OS-9 operating system is a very versatile environ-
ment. Perhaps most noticeable is that OS-9 gives you
a multitasking and a true multiuser environment.
There is a powerful feature in OS-9 that is often overlooked,
a feature often misunderstood. OS-9 can handle pipes and
filters!
"What are pipes and filters?" you ask.
Filters are programs that affect the output of another
program. They may be used to sort the output, delete portions
of the output, or add to the output. A pipe is the part of the
operating system that connects the filter to the parent or
master program.
Pipes and fillers are tied to OS-9's ability to perform multi-
tasking. They are essential for running two programs at the
same time and converting the output from one program to
the input for another.
The easiest way of getting a set of filters is by using what
is called a toolbox. The toolbox consists of a number of
programs that add flexibility to your OS-9 svstem. While
most of the programs do very little on their own, they provide
extra power for the overall system. There are any number
of different OS-9 toolbox kits available. My preference is
Computerware's Textools. Others are available from Frank
Hogg Laboratory, Microware and D.P. Johnson.
The simplest example of the use of pipes and filters is piping
something through a sort. This may come in handy when you
are working with a large directory (such as a 5- or 10-Meg
hard disk) or you have a large list in a file. We'll use the
example of a directory. First, look what happens when you
type dir. On my system it looks like this:
Directory of 'hd 10:15:05

Bruce Warner holds a bachelor 's degree in computer
programming, is president of the Northern Virginia
Color Computer Club, and owns Soft War, a docu-
mentation company. He is also an enlisted journalist
in the U.S. Navy.
This is a fairly large directory, so it's difficult to see if a
program or directory is there. You can find it, but with the
breaks in the lines, you'll probably get confused. What do
you do? For starters, you can use a program called Is (or a
similar name under one of the other toolboxes) to get a
directory that displays each of the files on its own line. It
makes my directory look like this:
0S9Boot
CMDS SYS

This makes your directory a little more readable, but it still
lacks a sense of order, which may be required for quick
reference. Since most toolboxes come with a Sort routine,
we can now take Is and "pipe" its output through a "filter"
called qsort to give us a sorted version of the directory. The
pipe command is represented by an exclamation point (!).
The command line looks like this:
Is 'hd ! qsort^p
You can replace the 'hd with any device name.
204
THE RAINBOW February 1987
This runs the program Is using a hard disk drive as the input
directory, pipes the output through the program qsort and
redirects the output to the printer. Now the listing looks like
this:

print_sty
startup
Notice that the order of the listing has changed. This is
because the output from the Is program has become the input
for the program called qsort, which put the listing in ASCII
order. This looks better, but it still isn't an alphabetical listing
of the directory, since the capital letters ( A-Z) all come before
the lowercase letters (a-z) when sorting in ASCII format (Z
is before a). If you've filed your directories using the
conventions recommended by experienced OS-9 users, this
could be used to tell you that the first section of the Is output
contains directories and the second section contains single
files (provided you have properly named your files). The
problem is that some files contain both upper- and lowercase
characters. So what good will the filter do?
Your next option is to use another filter to change the
listing to either all small or all capital letters. This will put
the entire directory in alphabetical order. You will lose the
identification of files and directories, but you'll know
everything in any directory. Just type!
Is ^hd ! lower ! qsort >'p
Again, the 'hd can be replaced with your device. This
executes the program Is to give a listing of all the filenames
on the hard disk. The output will be piped through a program
called lower, which converts all of the characters to
lowercase. The output from lower is then piped through the
program qsort. The qsort output is an alphabetical listing of
the directory. The final output is then redirected to the printer.
The new output looks like this:
assemb ly_source

Now that you have an understanding of pipes and filters,
take some time and see what you can come up with to increase
the power of the OS-9 operating system. Try something like
piping clsave through a shell.

Un-DISK Drives $49*85?
$34.95
You Bet! There are empty spaces in your 32K
and 64K CoCo. The Preble VDOS Un-DISK
helps you fill them up with PROGRAMS!
Un-DISK uses your computer's extra
memory like a fast disk drive.
Un-DISK can store BASIC and MACHINE
LANGUAGE programs.
Un-DISK is INVISIBLE. Yup! Un-DISK
does not interfere with normal Color Com-
puter Operation.
Un-DISK appears only when you type the
magic word VDOS.
Un-DISK comes with comprehensive in-
structions which you may not need be-
cause:

is self-prompting and easy to
Un-DISK is provided on cassette.
Un-DISK is faster than a slow clumsy
DISK DRIVE and best of all . . .
Un-DISK is CHEAPER thana DISK DRIVE!
Un-DISK will work even if you already own
a disk but WHY BUY A DISK AT ALL?
Un-DISK should be in the library of every
serious CoCo user even if you own a disk
says Frank J. Esser, independent reviewer
for rainbow Magazine!
OK sure, disk drives ARE NICE. I own one.
But if your finances are limited, the Un-DISK
can give you much of the power of the
mechanical drive. Even if you already own a
disk the Un-DISK can work like a super fast
extra disk.

Additional Power For S14.95
Only with VDUMP for the Un-DISK!
• VDUMP lets you make a cassette backup
copy of everything stored in the Un-DISK
• VDUMP lets you save 5, 10. 15 or more
programs on a single cassette tape file.
• VDUMP lets you switch Un-DISKs. With a
single load operation replace a group of
financial programs with a set of children's
programs. (The new VDUMP tape over-
writes the old.)
• VDUMP can allow you to save a whole lot
of rainbow on tape in a SINGLE file.
• VDUMP is the perfecl companion to the
Preble VDOS Un-DISK.
