LETTERS TO THE

Software Thieves
(Not Pirates) !
Editor:
This letter is to all the software thieves
who are passing around a broken version of
CBASfC VI, 01. It was discovered some time
ago that this version of C BASIC was avail-
able on BBSs around the country. When I
downloaded a copy, I was quite upset. I
spent over two years writing this program
only to find some thieves had stolen it and
were freely giving away copies. What gives
you the right to take two years of my work
and give it away or use it without my
consent? Not only have you taken something
that does not belong to you, you have also
given C BASIC a bad name. The copies you
are giving away are not even near the current
version (VI. 12) that has a large number of
additional commands, functions and im-
provements. Not only that, but the stolen
version has many commands and features
that no longer work after it was broken.
Some of you even have the nerve to
demonstrate it at computer club meetings
and discourage people who are considering
purchasing CBASIC. Then there are those
who have acquired the stolen version and
have the nerve to call us up and ask us why
something doesn't work.
Through greed or the desire to be the
center of attraction in the local CoCo
Community, you have succeeded in killing
the best Color BASIC compiler on the
market. You have also succeeded in cutting
our sales of CBASIC by over 50 percent. We
can no longer afford to run our current
advertisement since we no longer sell enough
copies to pay for it. I have to wonder, is it
worth it to continue to improve and enhance
CBASIC if I can't afford to pay for the
advertising? It also makes me realize that it
is not worth the time or effort to even
attempt to work on another program as
complete or complex as CBASIC for the
Color Computer.

May I offer some suggestions in response
to Kyle Johnson's query in the June 1986
issue [Page 8] regarding genealogy programs
for a 64K Color Computer 2.

Incorporating Print Styles
Editor:
In response to the question from Jerry
Dummer in the June 1986 issue [Page 9], he
asked how to incorporate various styles of
print (which his printer will print) within
Color Scripsit. I substitute the codes for
whatever character font I want to print in
place of the codes Underline and Elongate
in Option 7 on the main menu.
I hope this will be of help; your magazine
has certainly been a great help to me.

VIP Defended
Editor:
I take respectful difference with Richard
White for his statement in your May 1986
issue that VIP Writer might qualify as user
hostile compared with other offerings. VIP
is a powerful, elegantly programmed, and
very intuitive and logical word processing
package, with programmed-in and pro-
grammable printer controls that are beyond
belief. The kingdom of MS-DOS should
have a package as powerful and practical!
Neither WordStar or PC WRITE can touch
VIP for convenience and transparency.
I am a registered owner of Telewriter-64
as well as VIP, and I have a lot of respeci
for it. I don't doubt that you're right, Dar
(May 1986, Page 217): Telewriter-64 is
probably the most widely used word proces-
sor for the CoCo; it's a fine package and it's
been around a long time. But for my big
writing projects I invariably reach for VIP.
The recent patches for Telewriter-64 have
added a lot to the original, but they give it
features that VIP has as standard equip-
ment.
A VIP users' group was recently formed.
Interested persons can write me at Box 194,
01463. Hints, brief articles, letters, VIP
database formats and CALC templates are
gratefully received. There are no set dues,
but contributions to defray the cost of
copying and mailing the quarterly newsletter
are most welcome.

Transformation Troubles
Editor:
In the June 1986 issue, Marty Goodman's
article, "The Great Transformation" [Page
182] and associated programs are very good
and fill a substantial need. It is indicative of
the quality software available in the rain-
bow.
One problem is the interface between VIP
Writer and several MS-DOS word proces-
sors. Display Writer 3 and WordStar are
two MS-DOS word processors I have used
and both insert a carriage return at the end
of every line. On the other hand, VIP Writer
inserts a carriage return only at the end of
a paragraph (a forced line feed). Thus an
ASCII file from Display Writer 3 or Word
Star used with VIP Writer produces a
double-spaced output.
The problem becomes more serious when
sending ASCII files from VIP Writer to
Display Writer 3 or Word Star. The MS-
DOS software expects a carriage return after
every line and without them treats the entire
paragraph as one long sentence. It seems
that these problems are eliminated if

AUTOTERM!
IT TURNS YOUR COLOR COMPUTER INTO THE
WORLD'S
SMARTEST
TERMINAL
GOOD
LOOKIN'
AUTOTERM shows true upper/
lower case in screen widths of 32,
40, 42, 51, or 64 characters with
no split words. The width of 32
has extra large letters. Scrolling is
forward, backward, and fast. Block
graphics pictures are displayed
automatically and can be scrolled.
The screen's top line shows
operating mode, unused memory
size, memory on/off, and caps-
lock on/off. It also gives helpful
prompts.
SWEET
TALKIN'
KEY-BEEP can be on/off. Unac-
ceptable keystrokes cause a lower
pitched BOP! This ERROR-
BEEBOP can be on/off.
Talks to other computers with
Full or Half Duplex; Baud Rate of
110, 150, 300, 600, 1200; Parity as
even, odd, mark, space, none; 7
or 8 bit Word; any Stop Bits; all
128 ASCII characters; true line
Break; XON/XOFF protocol; and
optional line-at-a-time transmis-
sion. Able to send and receive
text, block graphics, BASIC and
ML programs. A 64K machine
holds up to 45,000 characters
(33,300 in HI-RES).
DUAL PROCESSING lets you
review & edit while more data is
coming in.
XMODEM for disk file transfer.
Fully supports D.C. Hayes and
other intelligent modems.

page size, margins, line spacing,
split word avoidance. Embed your
printer's control sequences for
boldface, underlining, etc. Narrow
text can be automatically spread
out.
You'll also use Autoterm
for simple word processing
and record keeping
You can display directories,
delete files, transmit directly from
disk, and work with files larger
than memory. Easily maintain a
disk copy of an entire session.
Compatible with TELEWRITER
(ASCII) & other word processors.
SMOOTH
WALK IN'
AUTOTERM moves smoothly
and quickly between word proces-
sing and intelligent terminal
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
anytime. 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!

THE WORLD CAN MATCH

Telewriter-64 is used since it inserts carriage
returns at the end of each line.
If anyone has a simple solution to this
problem, I'm sure it would be appreciated

Assessing the Assessment
Editor:
I must take exception to the article by
Harry HaJIstrom entitled "Assessing the
Market Value of Your Home," April 1986
[Page 79]. While Mr. Hallstrom's program
seems well-written and well-intentioned, it
does not assess the fair market value. I can
understand his bewilderment after talking
with three real estate agents who were
obviously lacking in training. Without facts
to back up their "market value," it is no
wonder they came up with a $20,000 range.
On the other hand, Mr. Hallstrom's
method neglects changes in the buying
market, availability and type of financing,
changes in the neighborhood, conformity
within the neighborhood, condition, area
amenities and more. In addition, improve-
ments rarely increase the value as much as
they cost.
Your readers would be best advised to
base their asking price on information from
comparable sales and competitive proper-
ties. If you live in a small town with no
multiple listing service and only local real
estate companies, go ahead and order a
FNM A appraisal. The cost of the appraisal
is small when compared to the frustration of
an extended marketing time and false expec-
tations.

HINTS AND TIPS
Editor:
Users of "Name That Tune" (June 1986,
Page 66) will experience problems with the
firebuttons regardless of the computer they
use. PEEK(G52B0) gives a number in the
100s or 200s depending on JOYSTI<(0). To
correct this problem, make the following
changes in the program:
5100 P=PEEK(G52B0) AND 3
In lines 51 10, 5120 and 5135, substitute 2
for 254 and 1 for 253.
Bruce Lewis
Maryville, MO
The substitution will work — and
it will work on both Co Cos regard-
less of what set of numbers your
firebuttons produce. However, it
also involves one more function to
be performed (computing the log-
ical AND on P) in a spot where
there is really no time to spare.
Hence, the joysticks become a little
less sensitive and the music moves
a little slower.

Ring Quest Reincarnation
Editor:
I enjoy your magazine and the Second
Adventures tape and would like to pass
along a hint for the Adventures tape. In Ring
Quest, to make it so you cannot die, make
340 GOTO 354. This reincarnates you with
a loss of hit points totaling the number the
monster killed you with, but at least you get
to finish the game. This is great for searching
rooms.

have a program called CoCo Knit-
ter. It was also reviewed in the
same issue (Page 195).
Diet Diagnostic
Editor:
Do you know of a nutrition and disease
program for the Color Computer 64K for
use with organic diseases, diet, vitamins,
symptoms, dates, hours, etc. My address is
4617 Girard Avenue No., 55412.
Wilma Bisted

The October 1985 issue, Page 213,
has a review of a program by
Homesoft called Nutriguide. This
may be what you are looking for.
Rabbit Relations
Editor:
I was recently approached by several
friends who are involved with rabbit breed-
ing. We are looking for a program to compile
information on rabbits for ease of record-
keeping. It would be similar to a genealogy
program. Has anyone seen or heard of such
a program? I would appreciate hearing from
anyone on this subject. I can be reached at
P.O. Box 775, 70664-0775.

Editor:
OS-9, to me, means incompatability with
all of my files that are in Extended Disk
basic format. What would I need OS-9 for?
Everything I ever use is in the normal
format. Why are there only hard drive
drivers for OS-9? It would be a great idea
to use a hard drive in place of a floppy! Then
I would have faster data I/O and lots more
space.
I could put CoCo Max Hand VIP Writer
8 THE RAINBOW August 1986
on it, etc. I know this would be possible if
I could get a software driver that would drive
a hard drive from Disk BASIC just like a
floppy but with the plusses of a hard drive.
More people would use hard drives because
they wouldn't have to learn another operat-
ing system and wouldn't have incompatabil-
ity with their existing programs. Does
anyone know where I can get a hard drive
driver for Extended Disk BASIC? If so, please
write to me at 125 Kelmar Avenue, 19355.

INFORMATION PLEASE
Editor:
Does anyone have a device driver and a
device descriptor for using the Radio Shack
X-pad under OS-9, or a program to use and
define the four special function keys on most
CoCo replacement keyboards for use under
OS-9, or an OS-9 sound program, or an OS-
9 key click program? My address is P.O. Box

Speechless
Editor:
I have purchased the Super Voice Car-
tridge along with the Translator from
Speech Systems. After reading instructions
and running sample programs it works fine,
but when I try it with other programs that
ask if I have a speech cartridge and I say yes,
it doesn't work. I have tried it with several
Radio Shack programs and on Gold Runner
from Tom Mix and it won't work with any
of these programs. I would like to know if
there is a program or a way to get the Super
Voice Cartridge to work with these pro-
grams. If anyone can help, please write me

CoCo Confusion
Editor:
I have a 64K CoCo. I received my May
1986 RAINBOW and looked through it. In the
"Received & Certified" column I saw the
Infocom games. I noticed it said the games
were for the CoCo 2. 1 know that the CoCo
2's POKE locations are different. Can I use
it on my CoCo? If not, are they going to
come out with one for the CoCo 1?
Ryan Smith
Placerville, CA
The Infocom routines require the
DOS command to boot. They
have, however, loaded on our
older CoCos when we used the OS-
9 boot routine to run them.
Take It All Off?
Editor:
Is it OK to turn off all the computer
equipment at the power strip, or should I
continue to turn off everything individually?
RAINBOWfest at Palo Alto was great.
Not only were there great bargains at the
booths, the seminars we attended were good
— especially the Steve Bjork seminar. We
also attended Dale Puckett's OS-9 seminar
and bought his book. Keep up the good
work, and please come back out our way
soon.

Although it is not recommended
by Radio Shack, it has worked
without detriment to the equip-
ment.
Documentation Dilemma
Editor:
I recently purchased a Centronics Model
308 printer for $50. 1 knew it was used when
I got it and expected it would not be in good
shape, but I was wrong. The problem is I
have no documentation on it. If anyone has
documentation please send me a copy of it
or tell me where I could get it. My address
is P.O. Box 56, 67103.

Packet BBS
Editor:
Have any radio amateurs found or con-
structed a packet bulletin board program or
message recorder/ transmittal program for
the CoCo in conjunction with two-meter
packet radio? I have experimented with the
Autoterm program (building keystroke
multipliers section), but the AEA PK=80
packet controller will not access these
commands when a station calls my station.
Any suggestions would be appreciated. My

I was pleasantly surprised to receive a
software update disk from one of your
advertisers, Micro Works. I had purchased
the DS69A Digitizer and C-See software,
and had found it to be a good product.
Apparently Micro Works found a bug, and
without any complaint from me, sent a new
version of their software. Your readers
should know that they are concerned for
their customers.

ordered some merchandise and am very
pleased. The person who took my order
explained what each piece would need to
work properly on my system and answered
all my questions. Half of the order arrived
in two days. One piece had to be back
ordered and it came in just four days. All of
this, plus fair prices, make FHL a company
for the CoCo Community.

How about a 'Wishing Well'
Editor:
I would like to see in rainbow a section
entitled "Programs I Wish Somebody
Would Write." Readers could write in about
a program of their particular interest that
might be of interest to many others with the
same need. I personally have use for more
business and science software rather than
games. It would be great if someone could
write a program for CoCo on linear pro-
gramming or a graphics break-even analysis
program. I would purchase these kinds of
programs, but nowhere are they written for
the Color Computer.

LATE NIGHT RATES
ON DELPHI
If all goes as planned, by the time
you read this, Delphi will have insti-
tuted summer Late Night Rates!
The way it works Is that, during the
late night/early morning hours, users
will receive one free minute for every
10 minutes used, amounting to a 1 0%
discount.
The Late Night Rates are to be in
effect during July and August and
apply to connect time between 2 a.m.
system time (Eastern Daylight Time)
and 7 a.m. local node time (the time
at your end). For Eastern U.S. users
this is a five-hour period, but for those
on Pacific Time, this is an eight-hour
period since Late Night Rates apply
from 2 a.m. syst em time to 7 a, m. local
time.
An added bonus to Late Night
Rates is that many of the rainbow
authors and editors choose to be on
our CoCo SIG during this period
anyway!
A Down Home
Invitation
Our Anniversary Issue is history now and we've already received
more notes, letters and cards about it than anything we've done
in a long time. As things work through the editorial department,
we'll print a representative number of your comments in our letters column.
Just about everyone had nice things to say, and all I can say is "thank
you!" We're glad you consider THE RAINBOW to be "your" magazine just
as you consider the CoCo to be "your" computer. It makes it a whole lot
more fun to be a part of the CoCo Community when you know everyone
is so positive about it.
Maybe the special section on the people who do THE RAINBOW whetted
a few appetites, or maybe it is just because summer is coming and it's time
to "hit the road" for vacation. Whatever the reason, we're getting a whole
lot of requests for tours of the Falsoft Building for this summer.
If you've already written to us about that, you know who to contact.
But if you happen to be near Prospect and would like to stop by, you can
arrange for a tour by writing or calling Ira Barsky, who is in charge of
our development program. Call or write Ira at our regular address and,
if at all possible, we'll be happy to have you. I'm sorry, but we can only
do this Monday through Friday during regular office hours (9 a.m. - 5 p.m.).
* * *
Speaking of Ira, our newest employee, reminds me to talk about
RAINBOWfest, which is also under his aegis.
The Chicago show this year was a resounding success, but proved to
me that I should let well enough alone.
One of the biggest complaints we've always heard about RAINBOWfest
is that the aisles are too small and there is not enough room to walk around
easily. In Chicago this year we took some extra space to make the aisles
wider. And what happened? The main response I got was that "the show
seems smaller than last year."
Actually, the Chicago RAINBOWfest had a slight increase in attendance
from last year (and were there some bargains to be had!), but it did seem
smaller because there was so much extra room.
Don't expect that to happen again.
After telling several hundred people
that the show was running the same,
attendance-wise, I decided that we'll
forgo the bigger aisles from now on.
And, we anticipate there will be
another major change for RAINBOW-
fest next year — two shows rather than
three. We will be in Princeton, New
Jersey, and Chicago, but the future of
the California show, right now, is in
doubt.
The California show has always been
our smallest — at least 2,000 less than
the other two — and has always been
the most expensive to produce. Part of
that is because of the great distance we
have to travel, but the other aspect is
that hotels in the California area (north-
ern and southern) charge far more for
use of their facilities than anywhere else
in the country.
We have not made a final decision yet
and hate not to go to the West Coast,
but we believe we might be forced into
dropping this one show because of a
combination of cost and attendance.
We are trying to find a way to cut
costs and boost attendance in Califor-
nia but we are not sure if those efforts
will be successful. If not, be certain that
the shows in Princeton and Chicago will
be held as planned.

My August column is traditionally a
pretty short one — I usually get "written
out" for the July anniversary issue. But
I did want to keep you up to date on
what's going on here and will close by
saying I hope we'll see you in Prospect
this summer!

OWL-WARE
WINCHESTER BASIC
ANNOUNCING... the Development of a Major Breakthrough in
HARD DRIVE SYSTEMS for the COLOR COMPUTER!!!
Several months ago OWL-WARE introduced the Finest OS9 Hard Drive System for the Color Computer.
No,w we are about to introduce the only RSDOS Interface System worthy of our computer, OWL-WARE
Winchester Basic. For the first time you have available a true Winchester System, although there are 10
directories made available to BASIC, the only limit to size of any file is the size of your drive. On a
10 meg drive you could have a 8 meg file on directory 5 and a 1 meg file on directory 8 and small files
everywhere. You turn the computer on and you can immediately access your drive from BASIC or any language
using commands you already know. You do not have to know or use OS9 to use OWL-WARE WINCHESTER
BASIC, but if you do, all files saved from RSDOS are available to OS9. All files generated from OS9 can
be made available to RSDOS by copying to the WINCHESTER BASIC directories. There are no partitions to
wall you into, only one operating system, but nothing forces you to use an operating system you don't like.
Call for further details and availability on this breakthrough product!!!

BUILDING AUGUST S RAINBOW
That plastic look . . .
A doctor in the house . . .
And, assorted CoCo commentary
A grab bag of sorts. Yes, the cover of last month's anniversary issue "feels
funny," or, as one reader says, "appears to be waterproof." Well, it was
laminated; that is, a "photopolymer," a thin plastic coating that dries
upon exposure to ultraviolet light, was added to give it a spiffier look. We
figured, with our mugs on the cover, we could use all the help we could get.
Perhaps "water resistant" would be more appropriate than "waterproof," to
borrow terms more associated with watches and raincoats than magazines.
Laminating a cover is much like waxing your car: it brings out the color to
make it look prettier and it helps protect the surface, too. For instance, if you
use a Magic Marker to draw mustaches on our caricatures, you can wipe them
right off again. At any rate, the lamination process was an extra feature of our
anniversary issue and, because it is quite expensive, it'll likely be a while before
we do it again. We hope you liked it.
Something brand new this month is "CoCo Consultations," a technical Q&A
column by Martin H. Goodman, M.D. Marty is a hard-core hacker if ever there
was one and, I believe, his knowledge of the CoCo and its associated hardware
and software is unexcelled. Our challenge here at THE RAINBOW will be to keep
Marty's voluminous replies in "CoCo Consultations" from spilling over into
the next dozen pages.
An added extra for rainbow readers is that Marty can be reached almost
every evening on our CoCo SIG on Delphi. Thus, you can receive quick replies
to your questions, even though, due to our "lead time," it may be months before
your question is published in his (or Dan Downard's) column.
I was recently treated to several hundred words of "clarification" from Marty
in response to a few dozen words in a letter to the editor in July's issue. It appears
one of our readers was somewhat overzealous in his comparison of the CoCo,
the Amiga, the Macintosh and the Atari 520ST.
No, the CoCo's Motorola MC6809E, most certainly, is not a 16-bit CPU,
as was claimed, but rather an eight-bit device, albeit with 16-bit internal
registers. Secondly, while 512K add-ons are available for the CoCo, only 64K
is directly addressable. There were some other inaccuracies, too, but, for Marty's
full response, youH need to check our CoCo SIG database.
Professor Art Flexser was one of the first to chide us for not contesting the
letter when we ran it, an editorial oversight. We've also received letters from
several others, including George Henry of Glendale Heights, Illinois; Lake
Smith of Mt. Juliet, Tennessee; Troy Rothwell of Battle Creek, Michigan; and
Alan Blount of Grand Junction, Colorado. The sum and crux of everyone's
remarks is that, yes, the CoCo is a wonderful machine, but let's keep the facts
straight.
Toward that end, we asked Bill Barden to do a piece on "How Does the CoCo
Stack Up?" Bill is a recognized authority on personal computers and his
commentary begins on Page 90. Perhaps this will make up for letting that July
letter slip through.
And, what else is new? Well, rainbow's technical editor, Dan Downard, is
about ready for us to introduce the long-awaited rainbow on DISK service,
which will include OS-9 programs, too. Stay tuned.
Lastly, we'll soon be mailing THE rainbow in Kraft paper — the infamous
plain brown wrapper — in order to provide extra protection during mailing.
So, if you've been putting off subscribing because you don't like the label being
stuck on the cover, now's your chance to join the ranks of those who save money,
and time, by signing up for home delivery. For this month, that's "a wrap" for
me, too.

of the Sand Worm
By Peter Meyers
had just seen the movie Dune
for the third time and had re-
tired to my C0C0 to think of
some great new program to
work on. I eventually gave up
that ridiculous notion and
began playing a game of Colorpede. As I played,
I thought about all the people with 4K CoCos
who are missing out on the fun. So with the ideas
of Dune still fresh in my head, I began work on
my program, Sand Worm.
Sand Worm is a Low-Res Centipede-type
game in which you are an underground mining
vehicle that must burrow through the sand,
destroy boulders, and (most importantly) avoid
the treacherous Sandworm.
After the title page appears, just press ENTER
and the game screen is produced. Use the right
joystick to control the red mining vehicle at the
bottom of the screen. As you move, you burrow
a path through the sand, but you must move
around boulders or destroy them to clear the
way for more burrowing. The firebutton triggers
the Ultrasonic Devastator, a sheet of sound that
breaks rocks (for three points) and petrifies any
portion of the Sandworm (for 10 points) turning
it to solid stone. Your score appears in the upper
left-hand corner, and the computer keeps track
of both the present and high scores.
The Sandworm also must maneuver around
the rocks, and when it hits one, it changes
direction, eventually moving downward to
Peter $(ime$ Meyers is a 15-year-old sophomore
at Tlw0a$ Jefferson High School in Rockford,
Illinois. He enjoys experimenting with graphics
and has owned his Co Co for six years and a
CoCo 2 for the past two.

VIDEO
A funny thing has happened in the home video
market. As it gets easier and easier to watch what
you want, it gets harder and harder to decide
what that might be.
Dozens of new tapes are released into the stores every
week, along with hundreds of hours of programming on
the network and cable channels. It has reached a point
where even the most devoted videophile can use a little
help sorting through it all.
Now that help is available.
Inside VCR you will find clear, easy-to-read reviews
of all the best new releases. You II find out about little-
known videos — what they're about and where to get
them. And in the feature articles, you'll find some very
entertaining reading about the entertainment business.
Now that you 've discovered VCR, you won't want to
risk missing a single issue. You can save yourself the
trouble of walking to the newsstand each month, and
save yourself some money at the same time.
Just fill out the attached card and drop it in the mail.
Or even easier, call (502) 228-4492 and ask for Sandy.
She'll see to it that VCR is delivered right to your door
each and every month of the year.

lestroy your miner. If any part of the
vorm collides with you, you are in-
stantly smashed to pieces. The worm
ilso possesses a natural burrowing
seam that breaks up rocks as well as
destroys you. When you are destroyed,
the worm restarts at the upper left-hand
:orner of the screen, a few more rocks
are added to the screen and you con-
tinue until all three of your miners are
destroyed.
When the game ends, the high score
is displayed and you are asked if you
want to play again. As long as you do
not end the program, the high score
remains updated throughout the games.
The best thing about Sand Worm is it
only uses 2.083 K of memory and will
run on the smallest of CoCos. I have not
included the famous speedup POKE
because my system will not accept it, but
those who want to should add it to give
more excitement to the game. The game
itself is pretty self-explanatory and you
should have no trouble mining the rich
soil of the desert planet with a little
practice (and a lot of luck). □

You'll use it all the time and love using it
What isCoCo 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.
"" " I wmm
j^Kfcu . . .... , ,
CoCo Max disk system, with Y-cebte.
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 15 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.

Zoom In t
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 fatbits (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 15, you can even
print your work in full color !
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 /asso.
Inside the HhRes Input Peck
a Hi-Res Input Pack?
Did you know that the CoCo joystick
input port can only access 4096
positions (64x64)? That's less than
1 0% of the Hi-Res screen, which has
49152 points! (256x192). 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
d igital converter. Your existing
joystick or mouse simply plugs into
the back of the Hi- Res Pack.
• ■
ing.
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

HARDWARE PROJECT
A Recipe to Fix
CoCo Fried Chips
By Marty Goodman
TT A is very rare that controllers just
I ^spontaneously cease to work. In
^nearly all cases the reason is
because the user has plugged, un-
plugged, or wiggled the controller in the
computer or Multipak port socket while
the power was on. What usually
happens is the positive and negative 12-
volt lines (on old CoCo Is and on
Multipaks) contact the adjacent NMI
and Halt line pins. Often this also burns
out the CPU (the 6809) and/ or the
SAM (6883, also given as 74LS783 or
74LS785) in the computer itself. Had
Tandy bothered, for about $1.50 worth
of zener diodes and SCRs it could have
fully protected the computer from such
abuse. But in all revisions of the CoCo
circuit board so far, it has not intro-
duced such protective circuitry.
Fixing the burned out disk controller
usually entails replacing the burned out
chips. This is facilitated by knowing
what chips are likely to get burned out
and by having a full set of spares.
Martin H. Goodman, M.D., a physi-
cian trained in anesthesiology, is a
longtime electronics tinkerer and out-
spoken commentator — sort of the
Howard Cosell of the CoCo world.
Marty is the database manager of rain-
bow's CoCo SIG on Delphi. His non-
computer passions include running,
mountaineering and outdoor photo-
graphy. Marty lives in San Pablo,
California.
Usually, on the newer controllers
only the main disk controller chip
(1793-002, MB8877a, or 1773), the disk
ROM and the write precompensation
chip (if any) is socketted. Most of the
small scale logic chips are soldered
directly to the board. You should be
reasonably adept in desoldering inte-
grated circuits. You should have on
hand a full assortment of all chips found
in your particular controller. A spare
controller of the same make and model
will give you access to the bigger sock-
etted chips and the smaller chips are
usually available at general IC supply
houses.
On most models of CoCo disk con-
troller, the 7416 (open collector buffer)
is quite vulnerable to damage from the
-12-volt supply. In three CoCo 2 con-
trollers I have fixed, both 7416s had to
be replaced. These are U3 and U8 on the
older type CoCo 2 controller with a 40-
pin controller chip, and U8 and U6 on
the newer Tandy controller that uses the
28-pin 1773 disk controller chip. The
74LS221 (one shot delay timer) seems
to often burn out as well. Occasionally
the main disk controller chip does, too.
On the old CoCo 1 controller from
Tandy, the 74LS02 and the 74LS04
chips (U9 and U5 on that card) have a
track record of blowing — sometimes
spontaneously. Be sure to look for
blown 7416s and 74LS221s on that
model. You should also have the asso-
ciated Tandy technical service manual
and a frequency counter. The potenti-
ometers may need adjustment so you'll
need the frequency counter to check for
proper setting.
On third-party model controllers, the
circuitry is often similar to Tandy's, and
thus the vulnerable chips are likely to be
the same. In the case of the old J&M
controller, the disk controller chip is
available only from J&M itself.
Oddly enough, the ROM chip on
these controllers seldom seems to be
affected. Indeed, once in the course of
repairing a controller I plugged in a
ROM upside down and turned on the
power. After realizing my blunder, I
turned off the power, inverted the ROM
and tried it again. Much to my amaze-
ment, the ROM functioned just fine.
In addition to these general tips, the
serious trouble-shooter will want sche-
matic diagrams of the unit to be re-
paired. Tandy and HDS both supply
such technical information on request
and for a reasonable sum. J&M in the
past was reluctant to release schematics,
but may be changing its policies.
DISTO agrees with the idea of releasing
schematics of its products to the public,
but to date has not made such informa-
tion available. It is my impression that
if enough customers insist on such
information before buying any product
from J&M or DISTO, both of these
companies will quickly supply it.

8 industrial relays on board. Contacts are rated at 3
amps You can control up to 64 cards (512 relays)
using several motherboards. Jumpers are used to
simply select the card address. The card Is easily
controlled in BASIC with "OUT" or "POKE". For
example, OUT 1 ,0 turns all the relays off on card #1 .
Eight LED's show which relays are on.
Digital Input Card in-141: $49
It's safe and easy to connect and read switches,
keypads, thermostats, alarm loops, etc. The eight
inputs can monitor the presence of voltage or switch
position. Simple INP or PEEK commands read the
status (On or Off) of the inputs. Each input is optically
isolated for convenience and safety.
Analog Input Card ad-142:$i 19
With this 8 bit, 8 channel A/D converter, your comp-
uter can read voltages, temperatures, pressures,
light levels, etc. Take over 1 00 readings per second
in BASIC (several thousand with machine language).
It's simple to use, for example: OUT 1,3 selects
channel #3, then A~l NP(1 ) reads the voltage on that
channel. Input range: 0 to 5.1V. Resolution: 20mV.
Conversion time 12Qus.
Prototyping Card pjm 52: $15
Protocard is 3 1 /a by 4W in, and accepts up to 1 0 IC's.
SHEILA wanted to set up a variety of experi-
ments in her lab. With an A-BUS, the computer
can watch the mice instead of Sheila.
HARRY has a model railroad layout that he wished
to automate. Now his home computer controls the engines]
gates, signals, etc. through the A-BUS.
BOB tests electrical fixtures as they leave the assembly line. He
develops test equipment quickly with inexpensive, off-the-shelf,
and easy to use A-BUS cards.
But what's an A-BUS ? It's the easiest way to con nect a variety of
cards that sense and control anything outside the computer. With
the A-BUS, your CoCo becomes an incredible machine.
What would I need? First, an A-BUS Adapter to convert your
computer bus to the A-BUS standard. Then a Cable (with one ortwo
slots) to connect one or two A-BUS Cards. If you need more than
two cards, the cable will be connected instead to the A-BUS
Motherboard, which has five slots. Up to five motherboards can be
chained. Finally, add you choice of A-BUS Cards to fit your project.
I'm not an engineer. Can I use the A-BUS ? If you can wire a
switch, you can use the A-BUS. No computer hardware knowledge
is needed I A screwdriver is ail you need for many projects.
What about software? Simple PEEK and POKE commands con-
trol the whole system, whether you read the time on the clock,
switch the relays, take a temperature reading, or turn a motor.
What if I change computers? Incredibly, this is as simple as
replacing the inexpensive adapter card.

Let Co Co take the tedium out of Adventure writing
ind leave the creativity to you
Processor
Developing an Adventure game
is not as difficult as one might
imagine. Adventures are sim-
ply a collection of data and a series of
true and false tests comparing the
player's inputs to a list of data stored in
memory of the computer.
The simplest way to store long lists of
data in a computer's memory is through
the use of arrays. Writing an Adventure
game generally requires that informa-
tion such as room descriptions, object
lists, authorized user inputs and key
responses be read into arrays so that
they may be called upon quickly.
Arranging the data, formatting the
text screen and processing of standard
commands is required in all Adven-
tures. Some programmers accomplish it
differently. I prefer to keep it simple and
easy to follow, since BASIC programs
should be a learning experience.
Bill Cook is a manager for the Navy
Exchange in Whidbey Island, Washing-
ton. He is the author o/The Adventure
Generator and wrote his first Adventure
in 1982. He uses the Co Co extensively
for business applications and as a
management aide.
About the Program
Imagine a program that could actu-
ally write most of the code for you,
automatically! A program that could
save you hours of tedious writing,
testing and debugging — a program
that would function error-free, and in a
matter of minutes save you more than
50 percent of the work in putting to-
gether your dream program.
AD V- PRO, or Adventure Processor,
is a utility to save you hours of tedious
typing of repetitive code. It simply
writes a "shell" of an Adventure for you.
It provides the following possibilities:
Up to 100 rooms, 60 objects and 30
commands.
A separate help message for every
location in the game.
Individual score values for each
object found.
Customized responses for each object
"examined."
Randomized object placement, if
desired, to make your game play differ-
ently every time.
Scroll-protected split screens.
Save game in progress/ load previous
unfinished game capability.
Operates with memory-stretching
PCLERR ZERO.
By Bill Cook
Outputs to tape or disk.
The first step in writing an Adventure
is mapping it out on paper. On your
map you should indicate the major
compass points at the top, bottom and
sides of the sheet. N, S, E, W, Up,
Down, should all be indicated for ease
in laying out the Adventure.
Each location should have a number
as should each object you plan to place
in the game. Have a good idea of the
vocabulary (verbs and nouns) you want
the program to recognize; two word
sentences are the standard. Once you
have completed this, jot down how
many rooms you'll have, the number of
objects and the number of commands
(verbs).
Using the Program
ADV-PRO asks you for the number
of items and limits you to 100 rooms,
60 objects and 30 commands. You are
also asked for the room number in
which you want the game to begin and
for a filename, You are then asked
whether to direct the output to tape or
disk. After answering these questions
ADV-PRO goes to work and creates an
Adventure "shell."
Within a few minutes, you will be
August 1986 THE RAINBOW 27
over half done with creating an efficient
and versatile Adventure game. ADV-
PRO writes to disk or tape, an ASCII
file that is a loadable basic program.
The pre-written coding sets up a ma-
chine language anti-scroll routine, frees
the maximum available memory, in-
itializes and reserves line numbers for
all of your room descriptions, legal
movement directions, help messages,
object descriptions, noun lists, object
score values, initial locations and verb
lists. You simply modify the program
with your customized data.
Here's a sample room description
DATA line as generated: 10 DATA ROOM
tt 1 DESCRIPTION, 0,0,0,0,0,0,
HELP MESSAGE HERE.
If you want room one to be described
to the user: YOU ARE IN THE LIVING
ROOM, simply change the line as follows:
10 DATA IN THE LIVING ROOM
,0,0, 0,0, 0,0, HELP MESSAGE HERE.
Notice that the "you are" is not neces-
sary. The program automatically pre-
cedes each room description with "you
are."
Next you decide in which directions
the player will be able to move from this
room. Let's assume that moving north
takes you to room three, south to room
four, east to room six, west to room 10,
up and down lead nowhere. These
locations should replace the series of
zeroes that come next in the above data
statement. Rooms that lead nowhere
remain at zero. The line would now read
like this:
10 DATA IN THE LIVING ROOM, 3, 4,
6,10,0,0, HELP MESSAGE HERE
Now for the help message. Assume
that the player is in room one and he
enters the command HELP. The re-
mainder of the DATA statement should
contain whatever response you would
like the player to receive. For example,
YOU SENSE A PRESENCE HERE. This
phrase becomes the final part of the
DATA statement: ■
10 DATA IN THE LIVING ROOM
,3,4,6;10,0,0,YOU SENSE A PRES
ENCE HERE
If you would like no help to be given
to the user, simply leave off the phrase
with the comma preceding it. This
causes an automatic response of NO
HELP HERE. Here's how the line would
look:
10 DATA IN THE LIVING ROOM
,3,4,6,10,0,0
The standard format for object data
looks like this:
152 DATA OBJECT tt 1 DESCRIPTION,
KEYWORD ,0,0 , RESPONSE WHEN
EXAMINED
As with the room descriptions, mod-
ify the line to enter your object descrip-
tion. Let's assume your first object is a
small rusty knife, you want it located in
room six, it is worth 10 points if carried
and if the player says EXAMINE KNIFE
you want the game to respond with IT
HAS A PEARL HANDLE. Here's how your
modified line should look:
152 DATA A SMALL RUSTY KNIFE,
KNIFE, 6, 10, IT HAS A PEARL
HANDLE.
If you would like an object to be
placed in the player's inventory initially,
use location -1. If you would like an
object to be placed in a randomized
location (unknown), use location -2.
Use of randomized object locations will
make your game play differently every
time.
Commands
The first seven commands the game
recognizes are already built in to the
game. They are: EXAMINE, INVENTORY,
QUIT, SCORE, HELP, SAVE and LOAD. All
the necessary coding for these com-
mands to function is already written
into your program. You can, of course,
modify the code, but it will function as
is. The remaining commands (if you
specified more than seven) are repre-
sented in the program as null strings.
The line would look like this:
508 V$( B) = ""
If you want the eighth command to be
GET, simply change the line as follows:
508 V$( B ) = "GET"
After making the changes to include
the entire verb list, you are finished with
the data portion of the Adventure.
Verb processing and conditional
statements are the toughest parts of
Adventure programming, and the most
time-consuming. Let's still assume verb
eight is GET. Processing for verb eight is
accomplished between lines 7500 and
7990. This is the area where you process
the different possibilities of reactions to
the player's use of the verb GET. This is
where you exercise your own program-
ming talent and creativity. Here is a
brief sample of what could be done:
7510 IF L0(N)=-1 THEN PRINT"Y0U
ALREADY HAVE IT.":G0T0 60000
7520 IF L0(N)< >L THEN PRINT"I
DON'T SEE IT. ": GOTO 60000
7530 IF CA=5 THEN PRINT"YOUR
ARMS ARE FULL.": GOTO 60000
7540 L0(N)~1:CA=CA+1:PRINT
"OKAY. YOU HAVE IT. ": GOTO 60000
Line 7510 checks to see if the object
is already in the player's inventory and,
if so, responds. Line 7520 checks to see
if the object is in the current room and,
if not, responds. Line 7540 places tt
object in inventory, increments tb
number of objects carried by one, an
responds that you have the object.

PRO-COLOR-DIR will read your directories and create a
master data file that can be accessed by PRO-COLOR-FILE
for sorting and reporting. 1000 + records can be stored on
one diskette with valuable information about each program.
You can obtain hard copies of the information and create
labels of the filenames for placing on the diskette itself.

@ SUMMARY
©1985 Derringer Software, Inc.
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" for each
expense then @ 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 wed as saved to disk.
The analysis can be saved in a "data file" which can be
loaded into DYNACALC or read in by 6 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 saved
in an ASCII file which can be read by word processors for
inclusion in a report.
@ SUMMARY is compatible with any spreadsheet program
that can generate an ASCII text file of worksheets.
* RS-DOS version included FREE with DYNACALC "

TELEGRAPHICS
© 1984 by Derringer Software, Inc.
PRINT HI-RES GRAPHICS USING TELEWRITER-64!
Use C0C0 Max, Graphicom or other graphics programs to
create letter heads and print them while using Telewriter-64.
Telegraphies interlaces with Radio Shack, Epson, Gemini,
C-ltoh and Okidata printers having dot-addressable graphics.
A simple modification to Telewriter-64 will allow you to exit
Telewriter via the DISK I/O MENU and print out the graphic
without affecting any of your text in the buffer.
This is the same feature that is included in our MASTER
DESIGN program. Since we felt you don't need to buy two
graphics editing programs, we have made this feature available
at a reduced price.

beautiful type for correspondence, reports, and
similar purposes. The LX-80 offers 160 different

control. Comes standard in friction feed; tractor op-
tion is also available.

THE COLOR COMPUTER MONTHLY MAGAZINE
It's called the premier Color Computer magazine for good
ason. THE RAINBOW is the biggest, best, brightest and most
)mprehensive publication a happy CoCo ever had! Is there any
onder we get letters daily praising THE RAINBOW, the
agazine one reader calls "A Pot Of Gold" for his Color
omputer.
THE RAINBOW features more programs, more information
id more in-depth treatment of the Tandy Color Computer than
iy other source,
A monthly issue contains 260 or more pages and two dozen
ograms, 15 regular columns and as many as 20 product
views. And advertisements: THE RAINBOW is known as the
edium for advertisers — which means every month it has a
ealth of information unavailable anywhere else about new
'oductsl Hundreds of programs are advertised in its pages
ich month.
But what makes THE RAINBOW is its people. Nationally
lown people like Bill Barden, who has written 27 books on
Dmputer topics and writes for us each month. Or, Fred Scerbo,
ho writes special programs at the request of readers. Experts
<e Dick White and Joseph Kplar, two of the most knowledge-
Die writers on BASIC. Communicators like Marty Goodman and
ray Augsburg, who stay abreast of telecommunications
jvances. Or, Dan Downard, RAINBOW technical editor, who
nswers our readers' toughest questions. Educators like Dr.
lichael Plog and Steve Blyn, who show how CoCo can be used
t home or school. Advanced programmers like Dale Puckett,
'ho guide you through the sophisticated OS-9 operating
/stem. Electronics experts like Tony DiStefano, who explain
ie "insides" of the CoCo. These people, and many others, visit
ou monthly through columns available only in THE RAINBOW.
Every single issue of THE RAINBOW covers the wide
pectrum of interests in the Tandy Color Computer — from
eginners' tutorials and arcade games to telecommunications
nd business and finance programs. Helpful utilities and do-it-
ourself hardware projects make it easy and fun to expand your
toCo's capabilities. And, monthly reviews by independent
eader reviewers take the guesswork out of buying new software
nd hardware products.
Join the tens of thousands who have found THE RAINBOW
o be an absolute necessity for their CoCo. With all this going
or ft, is it surprising that more than 90 percent of THE RAINBOW
subscribers renew their subscriptions?
We're willing to bet that, a year from now, you'll be doing the
;ame. For more information call (502) 228-4492. Or, for credit
;artf orders only, you may call (800) 847-0309.

What goes well with
the Rainbow?
Rainbow On Tape!
We call it the other side of THE RAINBOW and we may
have to raise the price just to call your attention to it. With
as many as two dozen programs every month, RAINBOW
ON TAPE is a luxury service at a bargain basement price.
What is it? RAINBOW ON TAPE is a monthly cassette
tape adjunct to THE RAINBOW and it's brimming with all
the programs (those over 20 lines long) that fill the pages
of the magazine. All you do is pop the cassette in your tape
recorder and they're ready to run. No more lost weekends
— or week nights — typing, typing, typing. With RAINBOW
ON TAPE, you can read the article in the magazine then,
in seconds, you load it up and run it. Yes, you could type
them in yourself, as many people do. But all of them? Every
month? There simply isn't enough time.
Isn't it time your CoCo became a full-time computer
instead of a typewriter? Think how your software library
will grow. With your first year's subscription, you'll get
almost 250 new programs; games, utilities, business
programs, home applications — the full spectrum of THE
RAINBOW'S offerings without the specter of keying in
page after page and then debugging.
RAINBOW ON TAPE — the ' meat'' of THE RAINBOW at
a price that's "small potatoes." Food for thought. To get
your first heaping helping, just fill out and return the
attached reply card. No postage necessary.
Discover the other side of THE RAINBOW. It's not only
a time-saver, it's the key to a whole new outlook!

Polar Tic Tac Toe is more than the old standby game
with the three-by-three grid. The game is played on
the pattern in Figure 1.
To win this game a player must place his mark in four
adjacent positions. These four may be in a semicircle within
any of the four circles. Or the winning four marks can be
in a straight line. This line of four may go through the center
of the pattern.
In the computer version of this game, players place red
and green sections on the original blue grid with their
joysticks. The program keeps track of turns, recognizes a
winning combination and keeps track of total wins for each
player. The loser of one game gets to go first in the following
game. There are a total of 52 ways to win the game. But
don't get overconfident, there are also 52 ways to lose. Good
luck. □

An educational game to encourage
mastery of word concepts
Which
When the first CoCos arrived in
our school I was thrilled.
However, the software we
ordered hadn't arrived and the class
needed something to use. This was the
perfect opportunity for me to learn
BASIC. It was one of my fourth-graders,
Jody Eason, who came up with the idea
to make a program like the matching
games they played in class. Nymatch
was born.
Matching games are popular learning
tools. Drill and practice becomes fun.
The cards are placed face down. Pick
two cards and, if they match, you keep
them and go again. The winner is the
one with the most sets. Add the CoCo
and you have an automatic answer
checker.
Nymatch can be used in any subject.
All you need are two ideas that share a
relationship. In history one such pair
could be Washington and first Presi-
dent. In math it could be 5+5 and 10.
For my subject I chose reading. More
specifically, Nyms. What are Nyms? I
Brim Dick lives with his wife and three
sons in Rensselaer, Indiana. He has a
master's degree in education and
teaches fourth grade. His hobbies in-
clude writing programs for his sons and
the classroom.
itch?
use Nyms as a broad category of words
made up of synonyms, antonyms and
homonyms. Synonyms are words that
have the same meaning (woods/ forest).
Antonyms are words that have the
opposite meaning (hot/ cold). Homo-
nyms are more confusing. Homonyms
are broken down into two types: hom-
ophones and homographs. Homo-
phones are two words that sound alike
but are spelled differently (deer/dear).
Homographs sound differently, but are
written the same. Read can be pro-
nounced reed or red.
Having a firm foundation in word
concepts is an important link between
reading words and understanding the
material. Reading some articles in THE
rainbow can be frustrating to those
unfamiliar with the topic. Understand-
ing what the words mean in the context
of the article is essential. One way to
strengthen vocabulary is to study how
words relate to other words. That is the
reason so much time is spent on Nyms
in school. That is the goal of Nymatch.
Nymatch works on 16K non-
Extended basic. Just type it in, save
and run it. If you own Extended BASIC
and get an OM Error, just PCLEAR 1
before running.
Although the game targets grades
three through six, it is valuable for you
as a parent to play with your child. Your

child may not be able to "sound out"
some words. Others may be used in a
new way. Your help early on can make
a big difference in how fast your child
masters the vocabulary in Nymatch.
Many children at this level are just
beginning to learn problem-solving
strategies needed in locating matched
pairs. For them, the game is reduced to
a guessing game. Playing with a parent
gives them examples of other strategies.
Since this game is so versatile, you
can add your own sets of matched pairs.
Making changes is not hard. You need
only modify two areas; the DATA state-
ments and the submenu explaining the

nformation. If you have 16K, there is
tot enough room to add any games,
fou will have to replace any set of cards
vith your own sets. Those with more
nemory can add to Nymatch.
Add your game to the main menu in
ines 550 to 590. Don't forget to adjust
he ON/GOTO line numbers in Line 70.
f you are adding more games, change
Jne 620. Add one to the five for each
idded game.
You will need a set of 30 matched
pairs for the DATA lines at the end of the
program. Each DATA line holds the
matched pair and its ID number. Re-
member that each set of 30 pairs must
be in the same order as in the menu.
Final Notes
1 hope your child enjoys Nymatch.
Learning can and should be enjoyable
whenever possible. Our CoCo proves
that over and over again. Isn't that why
most of us bought one in the first place?
Drop me a line if you are using a
CoCo in your school. I'd like to hear
from you, and I'm willing to help with
problems you have. Just send a descrip-
tion of the problem with a listing, if you
have a printer.

Part two of the translation demonstration
Uncomplicating Translating
By Joseph Kolar
Rainbow Contributing Editor
Before we dive in and immerse
ourselves in the nitty-gritty of the
second part of our translation
demo, I would like to make a few
observations.
We have gone from the germination
of an idea and, step by step, added to
it to broaden its scope. As a newcomer
to CoColand, you have helped con-
struct a program that is well within your
capabilities. There was no earth-
shattering concept to grasp. But, don't
expect to produce a viable program in
a day or two. You will find gremlins
lurking around and thwarting your
efforts every step of the way. No matter.
If you attend to the problem at hand
and solve it at every stage of the process,
you will have a usable, if not useful,
program.
Did you notice that as you created
this program, you had fun working out
each segment? In spite of yourself, you
began to associate the Romanian words
with their English mates. Not only were
you brushing up on your typing and
programming skills, but you were be-
coming familiar with the subject matter.
Florida-based Joseph Kolar is a veter-
an writer and programmer and special-
izes in introducing beginners to the
powers of Co Co.
This should hint at the potential for
educational applications you are begin-
ning to unleash. If you are familiar with
a Romance or Germanic language, you
may have spotted some cognates. The
perceptive programmer might wonder if
"raft" meaning "shelf," figuratively a
plank, is not related to "raft," a plat-
form for swimming, not to mention a
roofing rafter.
Did you save your work on tape?
CLOflD it. If not, copy Listing 1 from last
month's tutorial. Check out Line 10 to
make sure it is GOTD20.
Did you notice that, at times, we had
no operating lines 22 and 32? Delete
lines 22 and 32, then run. Again, we
have three sets of X$ and Y$ strings and
only one operating line, Line 42. CoCo
always chooses the last X$ or Y$ sen-
tence to operate on. Press break, then
restore lines 22 and 32. This observation
may be helpful in solving another reoc-
curring problem.
Key in, from this month's Listing 1,
lines 8, 50, 51 and 52. Line 8 prints both
sentences without an intervening pause.
List lines 50 through 52. Line 51 is a
word-by-word literal translation of
Line 50. Note, for the first time in our
demo, that the sentence in Line 51
extended to the second text line. The
invisible-vertical-line gambit is alive
and well. Line 52 depicts the usual
English translation.
Edit Line 10 at the end to GOTO50.
Add at end of Line 5 : G0SUB5 and run.
We allow the student/ viewer to look
over the sentence to be translated. Press
BREAK.
Add at end of Line 51 :G05UBB and
run. We display both the foreign sent-
ence and word-by-word translation
merely for informational purposes.
Unfortunately, it is a tortured English
rendition. Press BREAK.
Add at end of Line 52 :G05UB3 and
run. This displays the two sentences we
intend to dissect.
You can devise your own system. This
segment is included to give some ideas
as to how to approach problems of this
nature. You might revise G0SUB3 so
both languages are put on simultane-
ously to display lines 50 and 52. You can
also deep-six GDSUBs you do not intend
to use.
List lines 50 and 52. We decide to
break them into two parts. The most
practical break is after "George." Count
directly from the screen to get the 'P 1
and 'Q' values. Key in 53 P=12:Q=9:
Do not press enter yet. Recall that if
the next to last segment of a divided
sentence is put on using G05UB2, you
can use G05UB4 instead. Type GDSUB4
48 THE RAINBOW August 1986
nd press ENTER. Run the program then
ress BREAK.
Change Line 10 to 10 CLSZrGOTOGG.
Ley in lines 60 and 61. Press BREAK and
st Line 60. Note that each succeeding
jxt line begins under the opening quote
lark. You may also divide a word if
ecessary. The lines look odd because in
ine 60 there are no spaces between
/ords. This is because the words end at
he right margin, and the left margin of
he next row follows immediately, List
Jne 6 1 . You can easily spot the invisible
vertical line. This is because blank
paces were used to fill in the empty
pace up to the right margin so that the
lext words would start a new row at the
eft margin.
Key in 63 G0SUB3. This is a tempor-
ary use of GDSUB3 to display lines 60 and
61 in their entirety. It is good practice
to double-check long strings for correct
spelling and formatting before proceed-
ing. Run the program. The strings X$
and Y$ abut. It doesn't look good. One
solution is to drop Y$ two rows or 64
characters/ spaces at the beginning of
the operating line, Line 62. We want to
move *Y* location down by 64 spaces.
Insert Y=Y+64 : at the beginning. Run,
then press BREAK then CLEAR. List lines
60 and 61.
Our first part will end with the space
after and V respectively. Count
directly from the screen to determine
the first set of values, P=24 and Q=27.
Rekey Line 62 to read 62 Y=Y+64:
P=24:Q=27:G0SUB2:. Press ENTER.
Run and press BREAK, then CLEAR. List
lines 60 and 61. Edit Line 62 and enter
X.
The next part will end with "urc@"
at space 31 and "ascended" at space 38.
Add P=31:Q=38:G0SUB2:. Press
ENTER. Run and press BREAK, then
CLEAR. List lines 60 and 61. Edit Line
62 and enter X.
The next part, "pe tronul" ends at 41
and "the throne" at 52. You can pick up
the count either beginning at 32, a
known signpost at the start of text row
two, or pick up the last T' or 'Q' value.
You know that "ascended" ended at
Q=38. By looking at Line 62, start
tapping away with "TO — T=39,
O=40, space=41, etc., to the next divi-
sion. Enter P=41:Q=52:GD5UB2:.
Press ENTER and run it. Press BREAK,
then CLEAR. Edit Line 62 and enter X.
The next portion ends at the space
after "romaneshti." Pick up the last T*
value from Line 62 and count off. 'P'
will equal 57. The value ends after
"wallachia."
Look at Line 61. Note that "walla-
chia" extends across the invisible verti-
cal line. We know that *C is at number
64, so pick up the count from that point.
It ends at 68. Enter P=57:Q=68:
G05UB2 : . Press ENTER and run it. Press
BREAK and CLEAR. List lines 60 and 61.
Edit line 62 and enter X.
The next part ends in both X$ and Y$
after "1436." You can begin calculating
*P' from number 64 and you can pick
up the 'Q' starting number from the last
'Q' value, 68. Determine the values.
Enter P=71:Q=B5:G0SUB2:. Press
ENTER and run it. Press BREAK and
"This mistake may ~
dormant while you
are creating the
program, hut after
you finalize it, it pops
up to haunt you."
CLEAR. List lines 60 and 61. Edit Line
62 and enter X.
The next T' section ends after "ul-
cere®." Pick up the count from the last
*P' value in Line 62 (71) and count. The
next 'Q' value is the last word of the text
line "and tried." We know the next line
begins with number 96, so we subtract
one to get to the right margin of the
previous line to get 'Q\
Enter P=B2:Q=95:G05UB2:. Press
ENTER and run it. Press BREAK and
CLEAR. List lines 60 and 61. Edit Line
62 and press ENTER. This time we won't
'X' to the end. This would cause Line
60 to scroll up and off the screen, losing
our place. First, we will determine our
next break, which ends after "scape,"
picking up the count from Line 62.
Now, we can type X and P=91 : . Do not
press enter! The English equivalent is
"to free." We pick up the count by
counting down from the opening quote,
0, 32, 64, 96 and start counting. Add
Q=103:GO5U82:. Press ENTER and run
it. Press BREAK and CLEAR. List lines 60
and 61. Edit Line 62 and press ENTER.
We have one more break to do. Be on
the alert because, after we get our next
'P' and 'Q' values, we add G0SUB4
instead of GDSU82, then well be fin-
ished.
The last break is "tsara," which ends

just before our invisible vertical line and
therefore must be 95. Type X and P=95 : .
The last mate is "the country" and we
pick up 'Q' from Line 62 and count.
Type 0=115 :GD5UB4, press ENTER and
run. Whew!
It is suggested that you advance from
division to division until you feel com-
fortable with this system. Once you get
it under your belt, you can figure out the
operating line completely before you
check it out.
Did you notice the need to use CLEAR
when working on a long text line?
Let's consider the case of differing
word order between languages.
Type 10 CLSZ:GDTOB0. Key in lines
7, 70 and 71. List lines 70 and 71. "Om"
means "man" and "crud" means "cruel."
If we choose to break after "om," we
find the word "man" is further in the
sentence and we have a new problem:
to pluck out "man" without "the cruel."
We must use a new stratagem to pro-
duce parallel definitions.
We could chicken out and make the
break end after "crud" and "man"
respectively, but we won't.
Look at Line 7. This GOSUB allows us
to display X$ as usual. We use MID$ to
pull out the word we want and display
it first. MI D$ ( Y$ , Q , R ) tells us that from
a specified point, *Q\ in the body, M I D$,
of sentence Y$, we want to display 'R'
characters/ spaces.
First, recall that we pushed down
Line 61 64 spaces to Y+64. Since we are
returning to a normal line, we must
return 'Y' to its usual value. We must
begin Line 72 with either Y=Y-64 or
Y=22S. Otherwise, as we add numerous
program segments, some of which will
be overly long text lines, Y$ will be
displayed lower and lower and eventu-
ally drift completely off the screen, due
to a cumulative error.
This mistake may lie dormant while
you are creating the program, but after
you finalize it, it pops up to haunt you.
Back to work! We determine the
value of T\ 5. Type 72 Y=225:P=5:.
Do not press ENTER yet. Note the
following procedure carefully: The
word we want to appear first is "man"
with its leading and following blank
spaces (for aesthetic reasons). Since it is
in the body of the sentence we must
determine the values of MI D$ ( Y$ , Q , R ) .
We count on the screen from the
invisible vertical line, the number of
spaces up to and including the last letter
of the word in front of the word we are
targeting. It is the *L' in "cruel," 11
spaces. This is our offset 'Y* value,
Y=Y+il. Add Y=Y+11:. *Q' is always
one number higher than the offset 11.
Add 0=12 :.To figure out 'R\ count,
starting at 4 Q', the number of spaces to
be displayed (six)/ Add R=6:. To acti-
vate MID$( Y$, 12,6), we tack on
G0SUB7 : and press ENTER. Run it, press
BREAK and list lines 70 and 71 . Edit Line
72 and enter X.
We must return to the beginning of
Y$ to display "the cruel." We reduce *T
by the amount of the offset, 11. Add
Y-Y-ll:. We are ready to work up the
next word(s). The break in X$ is the
space after "crud," whose T' value is 1 1.
There are a variety of ways to pick up
'Q\ To be safe, count from the starting
quote up to and including the space
after "cruel" (even though this last space
is already displayed), Q=I2. Type
P=11:Q=12:G0SUB2:. Press ENTER
and run.
The next division is after "ishi" and
"himself." Press BREAK and list lines 70
and 71. Edit Line 72 and enter X. Type
P=15 : 0=26 : G0SUB2 : and press ENTER.
Run it and press BREAK. List lines 70
and 71. Edit Line 72 and enter X.
Next, we will break after "ucise" and

From Listing 2, list lines 70 and 71.
Key in the lines as lines 80 and 81. Now
list 80 and 81. Aside from the fact that
the word order is different, the equiva-
lent of "om" is "the man," not "man."
This is a split-section. This creates a new
problem that occurs frequently in Ger-
man verbs. Note the sentence "Ich
mache das fenster zu" where "zuma-
chen," meaning "to shut," is split —
"mache — zu."
The definite article is separated from
the noun in Line 81. Rather than work
out both the inverted word order and
the split-section at the same time, we
solved one problem, and now well try
both.
Key in Line 9. This GD5UB displays
X$ up to the break; Y$, to the first break
at 'Q'; then it skips to a second location
(Y+A+l) and pulls the balance out of
the body of the sentence.
G05UB9 handles the split-section in
the second language. If you need it for
the first language, your project is to
modify this line. If you can't dream up
a demo sentence to check it out, then
make the contents of Line 80 Y$ and X$
in Line 8 1 .
The T' value of "om" is five. The 'Q'
value of "the" is six. Count to the last
letter of the last word in front of the
target "man," 11, which is 'A'. 4 B' is
always the next space. B=12 and 'R' is
the number of spaces to be displayed,
six.
Type 82 P=5:Q=G:fi=ll:B=12:
R=6:G0SUBS, press ENTER. Run it and
press BREAK.
Figure out the next break, "crud"-
"cruel," P=ll and Q=12. Edit Line 82,
press X and ENTER, then type P=ll:
0=12:. Since we already displayed the
various parts in the last segment (lines
70 through 72) let's cut the agony and
finish. Type G0SUB4 and run it.
As usual, there is an easier version of
G05UB9, but it is not consistent with our
rigid demo format. Lines 100 through
142 contain a few more sentences. They
are a bonus for the dedicated pro-
grammer to study or work through for
practice.
You can delete lines 20 through 142
and use this program as a core to
translate sentences in some other lan-
guage. This program is great for self-
study. Crack open a conversational
grammar and sharpen your program-
ming skills while painlessly absorbing a
foreign vocabulary. □
"killed." Type P=21:Q=34:GOSUB2:.
Note that we pick up *Q' at number 32,
the invisible vertical line. We won't run
this one.
We decide to put on "dushmanii" and
"the enemy" next. The phrase, "f@r@
mil@" and "without pity" will be put on
as a unit. That being our plan, we are
alert to the fact that we are calculating
the next to Jast T' and 'Q' values. We
know that "dushmanii" is the last word
on the row, so we use the right margin
number, 31, or P=31. We pick up our
count from the last 'Q' value in Line 72
and count it out, 44. Type P=31 : 0=44 :
G05UB4. Press ENTER and run.
Checking out our handiwork, I see
that we could have placed parentheses
around "himself" because we don't
usually use the reflexive pronoun in this
context. You may want to alter Line 71
to do so. Be warned, some of your 'Q'
values will have to be revised. In fact,
you should be eager to work it out.
Refer to Listing 2, lines 71 and 72 to see
if you got the same answer. It is not
necessary to copy this listing.
That was the good news. Now, here
is the bad news. Lines 70 through 72
present another problem that I neatly
side-stepped.

THE RAINBOW'S
One-Liner Contest
has now been expanded
to include programs of
either one or two lines. This
^^■pr means a new dimension and new
^^^^^ opportunity for those who have "really
J^^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.
Send your entry
(preferably on cassette) to:

Accessories can make the differ-
ence between just a computer and
an efficient computer system. That's
why Radio Shack offers a wide se-
lection of accessories that make the
most of your Color Computer.
Save valuable time with the
Multi-Pak Interface (A, $99.95). It
connects up to four Program Pak™
cartridges so you can change pro-
grams quickly and easily. You can
change between slots with the
built-in selector switch, or under
program control.
If you like being a winner, then
this is the fast-action joystick for
you! With 360° movement and
single-shot control, these joysticks
give you the advantage every time
(B, Fair-$ 19.95).
With our FD-501 Thinline Disk
Kit (C, $299.95) you can turn your
Color Computer with Extended
BASIC into a full-fledged disk sys-
tem. Because the Kit comes com-
plete and ready to run — all you
have to do is plug it in and you'll
have 156,672 characters of user
storage per 5 1 U ff diskette.
Need the ultimate in storage ca-
pabilities? Then the Hard Disk
Interface (not shown, $129.95) can
give you just that.
Want quick and accurate control?
Let our Color Mouse (D, $49.95)
scurry across your tabletop to accu-
rately position the computer's cur-
sor movement.

sories for your Color Computer!

0S-9/TM Microware and Motorola.
Alter typing in the BASIC loader for
Starlord, save it to disk or tape. Then
perform a cold start on your computer.
Type in POKE 25, 57; POKE 14592,
0 : NEN to reserve room for the as-
t sembled program. Now CLORD the
BASIC loader back into the computer. If
you want w save the program as a
binary filc T delete Line 50. Run the
program. In approximately 30 seconds
the program will execute. If you deleted
Line 50, the computer simply prints OK
when it is finished poking the data into
memory. Now you can save it. Type CSR
VEfTSTFlRLDRD", 18240, 14430, 121
74 to save the program as a binary file.
Now all you have to do is CLDRDM and
EXECute to run the program. The pro-
gram runs on any Color Computer with
32K memory. Since the assembled ver-
sion will run on a 16K system, the
easiest way to load the program would
be to make a binary file of it on a 32K
system and then load the machine
language code on the I6K system. (The
BASIC loader takes up a little over 16K.)
Another, more tedious method, would
be to break the loader up into several
short BASIC loaders, each loading a part
of the total program. Then, once the
entire program has been poked into
memory, it can be saved as a binary file.
This process is tricky, so be cautious.
Stariord is a very exciting game
particulary at the higher skill levels
Here's a tip: A bullet takes longer to hi
a ship that is higher up so you must fin
in advance of the ship in order to hit it
Hitting ships becomes easier at th<
higher skill levels because the entire
game executes faster. I will be happy t<
answer any questions that may arise
Have fun!

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 ASCII 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 state
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.

Use this program to design
Escher-type graphics
Esch-A-Sketch
By Eric White
"No one can draw a line that is not
a boundary line; every line splits a
singularity into a plurality. Every closed
contour, no matter what its shape,
whether a perfect circle or an irregular
random form, evokes in addition the
notions of 'inside' and 'outside* and the
suggestion of 'near' and far away', of
'object' and 'background'."
— M. C. Escher
Ihave always been a great fan of
M.C. Escher and his self-
perpetuating patterns. Escher had
the unique ability to blend shape and
form with perfect balance. From his
drawings, one feels a sense of complete
unity and purpose of form.
In a search for techniques to create
Escher-type designs I tried many stand-
ard graphic techniques such as tracing
paper and pencil, but had little success.
When drawing a self-perpetuating pat-
tern, each line creates both an "inside"
and "outside" border simultaneously.
This can get quite frustrating as you try
to keep the subject recognizable. Need-
less to say this technique was time
consuming and tedious.
The main challenge is to draw both
sides of the subject at the same time. The
computer is the perfect medium to
attempt to solve this problem. Listing 1
is a short version of Escher. bas and
accepts X-Pad, Joystick or Hi-Res pak
for input. Type in the program and save
it before trying to use it.
You need to edit Line 440 with the
appropriate device number. This value
is stored in the variable DV. For the X-
Pad use a value of 1 (this is the default).
If you want to use a Hi-Res pak, use a
value of 2. Those using the standard
joystick port input need to set DV equal
to 3. Edit in the appropriate value
before running the program in Listing
I.
Listing 2 is a DMP-200 graphics print
program for use with pictures created
with Escher. bas. This program prints a
full 8-by-10.5 inch swatch of your
patterns.
I have learned a lot in experimenting
with Escher's world. I can't help but
wonder what he would have done next
if he had the use of todays microcom-
puters to continue his work. □

College
After two years of searching, we've
finally found a college football handi-
capper! We think it's a winner! The
Lockmaster® maintains stats on
105 major college teams, analyzes
the local point-spread, and rates the
game as a betting proposition. Why
waste your efforts on games with
marginal chances of success, when
you can get your Color Computer to
pick the games that are most likely
to make you a winner?
To use the program, all you need
are the College Football ratings that
appear each week in USA Today. You can run individual
games (including bowl games), update team stats and
customize each game's rating with critical information
such as coaching and quarterback changes and injuries
to key players.
Using the weekly stats and our mathematical formu-
la (which includes schedule difficulty, power ratings, of-
fense and defense), The Lockmaster rates each game
against the current point spread and tells you how sure
the bet is.
The Lockmaster is easy to use and menu driven. It in-
cludes complete instructions and data file for 105 major
college teams. 32K/64K Disk only. Just $39.95.

Mastering the Gates
By Keiran Kenny
This short game called Gates is not intended for sizzling
zappers of cosmic creeps, but for those who lack the speed
and dexterity needed to qualify as the fastest laser in the
western galaxy.
The screen shows five equally spaced fences. You are
the yellow spot at the bottom center of the screen and
must pass through the gates in all five fences in order to
reach home. The gates open and close at random and you
never know when a gate will open, or stay open long
enough to pass through.
When a gate opens in a fence, press the left- or right-
arrow key to move in the required direction, then press
the up-arrow key before the gate disappears and you will
pass through and gain 20 points. If the gate slams shut,
you bounce back and lose 10 points. Gates begins with an
initial bonus score of 500, which should be enough to
keep the score at a positive value.

Laying Down the Chips
By Bill Bernico
At one time or another, most everyone has played
bingo. It's one person's job to pick the little bingo chips
from a revolving drum and call out the numbers. In the
professional version, a plexiglass tank with 75 blowing
ping pong balls is used. One ball at a time randomly pops
up to the top as the next bingo number to be called. The
following program, Automatic Bingo Caller, simulates
this machine. It's not a bingo game but it randomly calls
all of the 75 bingo numbers one at a time without duplica-
tion.
Upon running the program two lines are displayed at
the top of the screen. The first line displays the numbers
already called. The second line tells you how many
numbers have not been called. Pressing 'C picks the next
number; 'B' and the game pauses so a player's card may
be checked for a correct bingo; and 'N' starts a new game.
If it turns out that a player did not have a bingo, pressing
'R' resumes that particular game. That's all there is to it!

Dnstrates the basics of flight. It takes a while to be able to
totally control the jet. The vertical movement of the right
joystick controls the right half of the horizon and hori-
zontal movement controls the left half of the horizon.
You can practice forever because the CoCo jet never
runs out of fuel!
Calling to Mind
By David Huang
Repeat It is a game that requires a good memory. Four
squares, along with the title and score, appear on the
screen. Press any key to start the game and a square lights
up with a short "beep." You must then press the number
(1-4) corresponding to that square. If the computer's se-
quence is repeated correctly, the score increments by one
and another square is added to the sequence. The se-
quence will be replayed by pressing the 'R' key. If a key is
pressed that does not correspond to the square in se-
quence, the game ends.
The object of the game is to repeat as many sequences
as possible to obtain a high score. Exceeding a score of 10
without replaying any sequence indicates great memoriza-
tion.
Enjoy!

Break Key Disable
By Eric Harrison
The following program should be particularly useful in
games and educational programs written for small chil-
dren. It first disables the break key, then places a ma-
chine language keyboard routine in memory. To call the
program use a GOSUB 50000 and then copy the variable
ZZ$ to whatever variable you want to use. This can be
done with a simple assignment statement. To allow entry
of a numeric variable, use VAL(ZZS) and assign this to
the appropriate variable.
Note that the BREAK key will work until Line 2 is exe-
cuted. Also, the break key is not disabled while in the di-
rect command entry mode. This is to allow for editing of
programs.
As written, the program requires 32K Extended Color
BASIC but can be altered to run on a 16K ECB system as
follows:
1) In Line 3 change the FOR loop values from &H7F00
to &H3F00 and &H7F0C to &H3F0C.
2) Change the CLEAR statement in Line 1 to CLEAR
G00,&H3EFF.
3) In Line 3 change the DEFUSR statement to DEFUS
RO=&H3F00.

Masonry Madness
By Andy Blount
Bricks is a Lo-Res puzzle-type game in which you must
move a stack of bricks from one side to another. All of the
bricks are different sizes and are represented by Xs. Only
one brick can be moved at a time and large bricks can't be
stacked on smaller ones.
To play the game use the left- and right-arrow keys to
move the 'G' and *P' across the top of the screen. The 'G'
represents getting a brick and the 'P' represents placing a
brick. To get or place a brick press ENTER and it disap-
pears or appears, if the move is not illegal. The score is
tallied by how many moves have been made; the lower the
better.

FEEDBACK
Scoreboard:
In response to Donald Dare's letter
(May 1986) concerning Dungeons of Dag-
gorath, there are five levels. The wizard is
on Level 5. 1 have killed him (and won the
game) several times.
You need the Joule and Rime rings plus
a certain sword and shield, Those two rings
must be 4t incanted" into their magic forms,
though. A dictionary is most helpful!
When you kill the "real" wizard, get his
ring, then "incant" it.
Also, iri Pyramid from Radio Shack, I
can only get a few treasures and have found
10 or so rooms. I always get lost in the
maze. I found the vending machine, but
ended up lost r— then dead. Send any help

You cannot get past the screening door
until you're near the end of the game. You
should be very persistent in going to the

KEEP YOUR GUARD UP
Scoreboard:
For those who have Knock Out by
Diecom and are having trouble getting to
the champ, this might help.
When starting out with Canvas Kid, put
your guard up and wait for him to move
slightly, then punch left. You should be
able to hit the first guy four times, then
wait until he moves again and let him have
it four more times with a left punch. You
should do this to all boxers except the
champ. Remember, though, the higher the
rank of the boxer, the less number of times
you can hit him.

ADVICE FROM THE DEAD
Scoreboard:
In three days I have solved Dragon
Blade and would like to offer some tips.
Although typing "help" in most places only
gets you a meaningless response, in two
places (both concerning water) it can be
very helpful.
To get past the first door you have to
follow the advice of the dead man and get
your hands dirty. Type REST when you
reach a restful place.
Throwing a rock at the right place keeps
you from getting killed.
In order to get past the stone door, you
have to search one other room very care-
fully.
I do need help on two other Adventures.
First, how do you get past the second
spider in Trekboerl Second, in my To
Preserve Quandic hint sheet, it tells me to
call Kendall when I'm trapped in the room
with the keys. But, when I call him he tells
me that I'm not in a desperate situation and
he won't help. How do I get past this?

I am a new reader of this magazine and
I want to give some hints.
In Offender, always "look" at the top
little section instead of the big principal
section. By looking at the small section, the
game is easier and you will make hundreds
of points.
In Pooyan (rounds two and four), don't
wait for the wolves to come up, or the
"thing" on top of you to fall on your head
when there are too many wolves on the
tree. Instead, start shooting at the coming
balloons (with no wolves). Doing this gets
you more points.
In Flight Simulator /, if you go north
from Airport 0, you will find the Tandy
Corp. logo picture and by flying north
from Airport 2 you will find an 'N' and an
arrow showing where the north is. Later,
you can find words saying "Flightsim L"
By flying east from Airport 0 you will also
find the words "Flightsim I" and by flying
east from Airport 2 you will find Airport
4 and an 4 N* with an arrow telling where
north is. Just before you run out of fuel,
you will find two mountains with a lake
and a river between them.
In Cashman, when there are no cats, go
up and get all the bombs that are being

How

you plunked down $69.95
/^and bought a Color Com-
J<-J VJputer on sale and now
you're wondering what you've gotten
into, eh? Or maybe you've had a Color
Computer for a while and you're won-
dering how the Color Computer stacks
up against other computers in the news.
Whether you're a new CoCo owner or
an old hand, every once in a while I
think it's a good idea that we stand back
and assess ourselves and our equip-
ment. Just how does the CoCo compare
to systems like the Commodore 64,
IBM PCjr, Macintosh, Atari ST and
others? This is not a task for the average
CoCo freak — he's simply too chauv-
inistic, too enthralled with the system
for which he spent hard-earned money.
I'm also biased, but I think I can separ-
ate my bias from the facts. I've been in
all types of computing since 1965 —
everything from mainframes to micros.
Currently I have a Radio Shack TRS-
80 Model I, TRS-80 Model II, TRS-80
Model 4, two Color Computers, a
Tandy 1000, a Tandy 2000, an IBM PC,
an IBM PCjr, a Commodore 64 and
assorted other smaller computers, like
the little-known Timex 2068. Want a
perspective about your machine? I think
I can do an unbiased job.
Eight Bits, Sixteen Bits, and More
Computer science students love to
beat each other over the head with their
computer systems the same way they do
with automobiles. "My Chevy can take
your Ford!" has turned into "My Mac
can run rings around your CoCo!" and
other insults. When I'm asked what
system I have at home, I tell them a Cray
X-MP. Since this is a ten million dollar
supercomputer, it shuts them up for a
while.
Whether you have a CoCo or Cray,
though, one of the ways computers are
compared is by the size of data pro-
cessed by the microprocessor inside the

THE RAINBOW August 1986
machine. Our Color Computers have a
6809 microprocessor, which handles
data in 8-bit chunks. (A bit, or binary
digit, can hold one piece of information,
a yes/ no or 0/ 1 piece of data.)
The 8088 microprocessor used in the
IBM PC, PCjr, and Tandy 1000, among
others, is widely touted as a 16-bit
microprocessor, but is really an 8-bitter
like the 6809. Both the 6809 and 8088
can perform some 16-bit operations,
but move data between memory and
central processing unit eight bits at a
time. The microprocessor used in the
Tandy 3000 and IBM AT is a true 16-
bit microprocessor, an 80286.
Many other microcomputers use
older microprocessors than the 6809 —
the Apple II series and Commodore
VIC-20 or 64, for example, use a 6502
microprocessor, decidedly an 8-bitter.
The Apple Macintosh uses a newer 16-
bit microprocessor, a 68000, as does the
Atari ST line and the Amiga.
So that puts the Color Computer on
a par with the microprocessor used in
the Tandy 1000, IBM PC and PCjr —
about midrange in today's market. The
question is, is a 16-bit microprocessor
twice as good as an 8-bitter? The answer
is not at all. Given a choice between a
16-bitter and an 8-bitter, I'd take the 16-
bitter, but I wouldn't expect it to do the
job twice as fast. If you've ever seen
some of the early Macintosh word
processing applications, you'd wonder
how such a fast microprocessor can
operate so slowly. More important than
the microprocessor size is how the
system is put together as an entire
package — hardware design, software
design, operating system and so forth.
To sum it all up, let's give the Color
Computer a seven out of a possible 10
for the microprocessor.
The More Memory the Better?
The Color Computer has a maximum
memory limit of 65,536 bytes, each byte
capable of holding one character of
data, or about one basic keyword. Not
all of this memory is available for user
program storage, though. Normally,
about half of the memory holds the
BASIC interpreter. The remaining 32,768
bytes is an enormous amount of mem-
ory compared to minicomputer systems
of the 1960s, many of which used only
8,192 bytes to run their programs.
However, the 32K (K standing for
1,024) bytes does pale in comparison to
the 640 K bytes available on the Tandy
1000, IBM PC, and PCjr, and the
millions of bytes available on more
recent systems such as the IBM AT and
Tandy 3000. How much memory is
really needed?
It really depends upon the task, but
generally, the more memory, the better.
Part of the reason people clamor so
much for additional memory is that
applications software packages like
Lotus 1-2-3 are memory hogs — they
require hundreds of thousands of bytes
to run. However, there are many other
packages that do not require such huge
amounts of memory. Perhaps 90 percent
of all software programs will run in a
32K byte system.
Systems like the Commodore 64 and
Apple II series have about the same
amounts of memory as the Color Com-
puter. However, there's no question that
this is one area in which the Color
"More important than the
microprocessor size is how the system
is put together as an entire package —
hardware design, software design,
operating system and so forth/'
Computer could stand some beefing up.
If a new Color Computer is released,
we'll certainly see additional memory as
an option, perhaps as much as 512K. In
the meantime, the Color Computer can
run virtually any application, due to the
large amounts of software packages
available from Radio Shack and out-
side vendors.
Because the Color Computer could
use more memory, we'll give the CoCo
a three out of a possible 10 on memory.
Good Graphics
One of the nicest things about the
Color Computer is its graphics — a
maximum of 256 pixels, or dots, per
August 1986 THE RAINBOW 91
horizontal row by 1 92 pixels per vertical
column, making a total of 49,152 sepa-
rate dots on the screen, each of which
can be one of two colors. Another mode
allows 128 by 192 dots in four colors.
How does this compare to other sys-
tems? At the top of the line is the
Commodore Amiga, which has a max-
imum of 640 by 400 pixels in 16 colors.
Next is the Tandy 2000 with 640 by 400
pixels in eight colors. The Atari ST is
in this 640 by 400 range. The Enhanced
Graphics Adapter of the IBM PC al-
lows 640 by 350 pixels in 16 colors. The
Apple II series allows 560 by 192 pixels
in 16 colors. The standard IBM PCjr is
next. The PCjr graphics is virtually
identical to the Tandy 1000 — 640 by
200 pixels in four colors. The Apple
Macintosh has 512 by 342 pixels, but
only in black and white. At the bottom
of the range are machines like the Atari
1200 series with 320 by 193 pixels and
older machines with even less resolu-
tion. The Color Computer is in this last
category.
You can see that the Color Computer
is marginal as far as graphics goes —
newer machines are tending towards
better and better graphics. Of course, to
get the better graphics, you need an
expensive color monitor at perhaps
$400 extra over the cost of the system.
Then there's the fact that 640 by 400
pixels in 16 colors requires a meg-
abyte(!) of memory and a great deal of
time to process. The result is a very slow
screen update. With 128 by 192 four-
color and 256 by 1 92 two color graphics,
Color Computer screen updates can be
done rapidly, and you don't need huge
amounts of memory to store additional
screen pages.
Again, though, I'd have to say that
the more screen resolution, the better,
even if the full capability of the system
isn't realized. Let's give the Color
Computer four out of 10 on graphics.
Languages
Most computers have a built-in BASIC
language capability — the IBM PC and
PCjr do, as does the Color Computer.
The interesting thing about BASIC is that
most versions of it have been pro-
grammed by Microsoft, a software
company in Bellevue, Washington that
got in on the ground floor of microcom-
puters and has remained a major
market force. As a result, Color Com-
puter BASIC (including Extended BASIC)
is remarkably like the PC and PCjr
BASIC in many respects. The LINE,
CIRCLE, and other graphics commands
are virtually identical to those used on
the IBM PC/ PCjr. Color Computer
BASIC is therefore a strong BASIC that
is much more of a standard than BASICS
such as Applesoft BASIC or Commodore
BASIC.
Currently, the most popular compu-
ter languages are basic, pascal, c,
FORTRAN, COBOL and assembly lan-
guage. All of these are available on the
Color Computer via the OS-9 Operat-
ing system. OS-9, of course, doesn't
come with the system. It's a fairly
inexpensive option, however, and you
can pick the language or languages you
require. The IBM PC and PCjr also
have all languages available for them,
but many of the other systems, espe-
cially the newer ones, may not have
certain languages. Assembly language is
generally available on all systems — I've
mentioned the EDTASM+ product —
and other assembler programs are
available for the Color Computer as
well. Assembly language is a difficult
language in which to program, but it
produces extremely fast programs.
As far as languages, therefore, I'd
have to give the Color Computer a nine
on a scale of 10; just about everything
you'd want is available, although you
do have to use the OS-9 operating
system in some cases.
Operating Systems
An operating system controls system
resources such as printers and disk
drives and it acts as an overseer to
control all system operations. Although
Disk BASIC is called Disk BASIC, there
are many functions in BASIC that would
properly belong in the operating system
realm; commands like DIR, KILL and
LDADM. The intent of Radio Shack was
to make a simple operating system, and
they succeeded very well — the Disk
BASIC operating system commands
include most of the common things
you'd want to do with any operating
system.
In addition to Disk BASIC there's the
sophistication of OS-9. OS-9 is a Color
Computer form of the Unix operating
system, an operating system developed
by Bell Telephone Labs and touted as
one of the best around. Personally, I'm
less enthusiastic than most about OS-9
and Unix. It's sophisticated and versa-
tile, to be sure, but it's not very friendly
and hard for the beginner to use. How-
ever, I would rank OS-9 above such
operating systems as the MS-DOS used
on the IBM series and Tandy 1000,
1200, 200 and 3000.
Without OS-9, I'd have to give the
Color Computer four out of a possible
10; with OS-9, it gets an eight — one
point is taken off because of OS-9's
complexity.
The CoCo User Base
It's funny how you can have an ex-
citing computer, but if the system
doesn't take off, nobody develops soft-
ware for it, potential buyers lament the
lack of software and delay their pur-
chase or buy another system, and the
product may fail. This was the case for
many computers over the last ten years
or so — computers such as the Timex
2068 and Coleco Adam. One current
product for which this may be happen-
ing is the Commodore Amiga, which
seems a little expensive for the impres-
sive graphics possible on the system.
The base of users for the system, then
is very important. It takes sales of
hundreds of thousands of systems be-
fore the snowball effect works the other
way, inducing more and more people to
develop software for the system, design
system add-ons and produce other
related products. Current estimates of
sales for the Color Computer are about
1.5 million units! That's not a bad
figure, to say the least. For contrast, the
IBM PC is one of the best selling
computers of all time, certainly in the
millions of units. The Commodore 64
"One-and-a-half million users can't be
too far wrong — let's give the Color
Computer a nine out of 10 for the user
base."
92 THE RAINBOW August 1986
ind VIC-20 have also sold millions. The
\pple Macintosh has probably sold in
he high hundreds of thousands. The
BM PCjr has sold in the low hundreds
)f thousands. Systems such as the
Zoleco Adam or Timex 2068 have sold
)nly tens of thousands. The Color
Computer, then, is toward the high end
}f sales compared to other systems, but
s not the all-time best selling small
computer.
With 1.5 million units, however, the
CoCo has a plethora of hardware and
software products. IH just mention a
few that have blown my socks off.
There's CoCoMax, a terrific color
graphics/ mouse program which rivals
the Macintosh MacDraw, but in color!
There's EDTASM+, one of the best
assemblers on the market today in terms
of interaction with the user and inte-
grating editing, assembling, and debug-
ging facilities. There's OS-9, the profes-
sional Operating System for the Color
Computer which enables several tasks
to be run concurrently on the CoCo and
provides more than enough power for
even a jaded mainframe user. However,
there are a lot of small products too,
ranging from the Y cables sold by
Spectrum Projects to the neat games of
MichTron. The point is, there's a huge
user base and a full spectrum of pro-
ducts to support the computer, which
you certainly will not find in systems
which haven't made the grade.
One-and-a-half million users can't be
too far wrong — let's give the Color
Computer a nine out of 10 for the user
base.
Cost
This is a subject dear to everyone's
heart and probably is the biggest single
factor in a small computer purchase. At
the RAINBOWfest in Palo Alto earlier
this year I saw 16K Extended BASIC
Color Computers going for $59.95!
Those types of prices make the Color
Computer a tough system to beat.
Another decided plus in favor of the
Color Computer is that the system is
modular — you can start off with the
basic box and then add disk drives and
other equipment as you require.
Figuring an Extended Color Compu-
ter with a single disk drive, 64K of
memory, and color television monitor,
the best current price would be about
$600. The Atari ST with monitor is
about $700. A Tandy 1000, an excellent
buy, can be purchased for about $1000
with color monitor. The Commodore
Amiga with monitor is about $1400. An
IBM PC with a single drive and color
monitor is about $1800. The Color
Computer, then, is not as dramatically
different as you might expect when it
comes to price, but it sure is an easy
system on which to start off inexpen-
sively, and one that will grow with you.
However, there's another factor in
price. Lotus 1-2-3 for the IBM PC costs
Other people run only Lotus 1-2-3 and
would like huge amounts of memory for
their spreadsheets. Still other owners
are into languages such as C and assem-
bly language and want a system that
runs their favorite compiler in a friendly
environment. Other users want a system
with good, inexpensive graphics games
for their kids. I'll leave it up to you to
"Do I like the Color Computer?
Somehow it exudes a user friendliness
my IBM PC just can't compete with."
$300. The Microsoft C compiler for the
PC costs $250. Contrast this with the
$29.95 for Radio Shack's "Spectacula-
tor" and $99.95 for the OS-9 C compiler
on the Color Computer. Just walk
through the aisles of any RAINBOW-
fest to see how inexpensive hardware
and software for the Color Computer is.
Let's give the Color Computer a
seven out of 10 on the basis of its
bargain prices for an overall system and
inexpensive hardware and software
add-ons.
To Sum It All Up
At this point we can tabulate the
different categories we discussed above.
A lot of this, I admit, is somewhat
subjective, but I've tried to be unbiased.
Here's the scorecard:
Microprocessor
Memory
Graphics
Languages
Operating System
User Base
Cost
7 out of 10
3 out of 10
4 out of 10
9 out of 10
8 out of 10
9 out of 10
7 out of 10
Obviously simply adding up these
counts won't give you an absolute figure
on how the Color Computer stacks up
against the competition. The biggest
reason for this is that the criteria above
must be "weighted." With some users,
cost is a very important factor, with
others, the difference between a $3000
Tandy 3000 system and an $600 Color
Computer system is no problem at all.
determine your own needs and how
much weight you'd like to give each
factor.
From the comparisons above,
though, I think it's fair to draw the
following conclusions: the Color Com-
puter is an inexpensive system with
inexpensive software and hardware
add-ons. The system uses a fairly recent
microprocessor that provides adequate
computing power. Memory is limited,
but large enough to run most applica-
tions. While the graphics don't match
the graphics of newer systems, they are
adequate for most applications and
games. The Color Computer has a wide
range of languages, a good basic oper-
ating system, and a harder-to-use, but
powerful, advanced operating system.
It's user base guarantees good support
from the manufacturer and developers
of hardware and software products.
And now for my personal, strictly
biased opinion: Do I like the Color
Computer? Somehow it exudes a user
friendliness my IBM PC just can't
compete with. I like the classic lines of
the instruction set of the 6809 micro-
processor. I even, believe it or not, like
the feel of the keyboard. When I see the
graphics on such programs as Sands of
Egypt or Co Co Max, I forget that the
resolution isn't quite as good as a Tandy
1000. I especially like wandering down
those aisles at RAINBOWfests, picking
up fantastic bargains on hardware and
software. The CoCo will be around for
a while in my computing room and I
hope in yours as well.

of books and library arrangement, use
of encyclopedia or reference book letter
keys, reference guides, card catalogs
and the use of a variety of reference
books. These reference books include
encyclopedias, atlases, almanacs, year-
books, telephone directories and news-
papers. The students often collect and
organize materials for class assignments
or their own class library.
One skill we feel dominates library
use is the card catalog. The ability to
properly use it often determines if one
can locate the proper material one
needs. Some libraries are now using
methods other than the traditional card
catalog. The newer methods usually are
less expensive to the library. Whatever
the system, the material it contains is
similar.
This month's program will help fa-
miliarize students with the information
contained on cards from a typical card
catalog. An illustration of a typical card
is shown. The student is asked to locate
the author's last name, the title, the
publisher and the number of pages.
Lines 30 and 40 set the dimensions for
the number of cards. Lines 50 through
70 read the cards' information from the
DATA lines. Lines 80 through 300 ask the
questions about the four pieces of
information we are looking for. If the
answer is correct, a pleasant tune is
heard. If incorrect, the correct answer
is inserted in the proper place.
The DATA lines contain the cards'
contents. They are entered in the follow-
ing manner: author's last name, au-
thor's first name, title of book, illustra-
tor, publisher, copyright date and
number of pages.
Please note there is no comma at the
end of the number of pages which is the
end of the DATA line. Placing a comma
here is a common mistake that alters the
results desired.
There are currently only five cards in
our catalog. You may add an almost
endless number of cards if you desire.
Merely follow the DATA line pattern
started by the program and shown
above. Enter your DATA on lines that
you create following Line 420. Be sure
to adjust the value of 'N' on Line 30 to
the new total amount of cards.
We, at Computer Island, hope that
you will use and modify this program
for your children's needs. It would be a
nice experience for the children to assist
you in selecting more books to include
and in entering the new DATA lines. □

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 51
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 fan. 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
Telewriter. 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-64 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 are
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
time 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 see is what
you get." This makes exact 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

EDUCATION OVERVIEW
The ^Hidden' Computers
By Michael Plog, Ph.D.
Rainbow Contributing Editor
The education industry is com-
prised of much more than
teachers and students. Many
people work for education, but never
see a classroom, or even a school. Yet,
their work is important, and helps to
make teachers' jobs more productive.
Computers play a role for these people
too, and assist in getting an educational
product developed and delivered.
One example of such an educational
effort is the production of educational
television tapes for schools and general
public. Preparation of a videotape can
be a very simple affair, providing you
do not mind a low-quality final product
with an amateurish appearance. With a
video cassette recorder and a video
camera, anyone can take home movies
and show them in classrooms. Produc-
tion of a high-quality tape, however, is
an entirely different matter.
Before videotape, preparation of an
educational film could also have been a
simple affair. Many people owned home
movie cameras and took movies. An
amateur could even edit the film by
looking at each frame of the film,
cutting and splicing until the edited
version was more acceptable to the
audience. With videotape, editing can-
not be done with a sharp blade and glue.
You cannot simply cut a piece of video-
Michael Plog received his doctorate
degree from the University of Illinois.
He has taught social studies in high
school, worked in a central office of a
school district and currently is em-
ployed at the Illinois State Board of
Education.
tape and attach another piece to it.
Electronic editing is required.
Another problem of video editing is
school students (and members of the
public such as school board members,
parents, etc.) have a more sophisticated
attitude toward educational video
materials than in the past. The quality
of the message is often measured by the
quality of the medium. We have been
spoiled by slick network production,
not to mention Sesame Street and other
professional material now available for
educational use.
Editing a videotape has some similar-
ities to editing celluloid film. A video-
tape has frames, much like a film has
frames. On celluloid film, a single frame
is one picture, one exposure of light
onto the film. One frame of a videotape
is a sweep of the cathode ray gun down
the video screen. There are thirty such
complete sweeps every second, there-
fore a video frame is 1/30 of a second.
To edit a tape, you need to record the
frames wanted onto a new tape. A blank
tape is used to receive the images from
other tapes. The final recording has to
be in the proper sequence, even if that
means going backwards on one of the
raw tapes.
Every videotape contains the image
plus other information. Each frame has
room for 80 bits of audio information.
Some of that information is used as a
time code track. Each frame of video
tape has a code that tells the hours,
minutes, seconds and frame number. A
technician can call up the exact frame
of a piece of tape that is two minutes,
14 seconds, and 29 frames from the
beginning.
Now we see how to edit videotape.
The director can indicate the final tape
should begin with the shot happening
four minutes, two seconds, three frames
after the start of the raw tape, go for 20
frames, then insert the shot that is one
hour, eight minutes, five seconds and
three frames. This process continues for
the entire length of the finished product.
This type of editing is much more
difficult than cutting a strip of celluloid
and physically inserting it at the right
place.
There are companies that provide the
equipment necessary for such editing.
One machine is required to record the
final product and, generally, more than
one machine is used to provide the
incoming source tape, since most people
will have more than one reel of tape
containing the original information.
Recently, I observed such an opera-
tion at the television section of the
Illinois State Board of Education. One
recording machine was connected to six
source tape players. Two other input
devices were used to control screen
graphics. The editing process was
handled by a computer, as you might
well imagine. The impressive part of this
educational television facility is that a
Radio Shack Color Computer is the
machine controlling this massive array
of complex electronic video equipment.
That's right — the little white box from
Tandy, almost unnoticed among dials,
knobs, blinking lights and huge ma-
chines, was the brains of this operation.
The Color Computer has several jobs
in this facility. It must first touch and
read each of the incoming tape ma-
chines and the recording machine. The
August 1 986 THE RAINBOW 97
computer has to determine if the tape
machine is on with a tape correctly
inserted and ready to play. The compu-
ter provides commands to each of the
machines to stop, get ready, play, and
most crucial of all, to determine the
frame position called for by the director.
The creator of this system, Mitch
Hopper, loads up to six tapes, then sits
at the keyboard of the Color Computer.
He types in a command to record from
one of the input machines, beginning at
a specified location, for the required
length of time. There are hundreds of
such commands necessary for one final
tape. Each command is also listed to a
printer for later verification and track-
ing of the finished tape.
The computer then goes to the spe-
cified input machine, reads the time
code, determines how far away (and in
which direction) the requested time
code is, moves the tape back and forth
until it has found the correct beginning
spot. The exact frame of the input tape
is then noted. To further complicate
matters, the electronic devices have a
delayed reaction time. A tape machine
cannot simply begin playing, it first has
to get up to speed then start showing the
signals for that frame. Each input
machine has a different delay time,
meaning the Color Computer has to
keep these times straight for every
machine.
Finally, the Color Computer must
start the machine providing the incom-
ing signal, as well as the recording
machine, at exactly the correct time, so
the specified frame — not one frame
ahead or behind — is recorded on the
final product. With thirty frames per
second, the job requires the combina-
tion of high quality in computer, soft-
ware and operator.
I was amazed when I found the Color
Computer performing this task. I was
even more amazed when the man who
developed this system said he had
written the entire program in BASIC.
Machine language would have been
faster than BASIC, but would not greatly
increase actual speed, because of the
time required for a human to change
tapes on the machines.
The total material investment in this
system was one Color Computer, a tape
player for the computer (no need to use
disk; the program stays in the machine),
and about $250 for a Programmable
Peripheral Interface box. The- PP
contains extra memory and the addi
tional ports necessary for "talking" witl
the tape machines. No monitor wa
necessary, there were plenty just laying
around. After all, this is a facilit]
devoted to video. Mr. Hopper spent sij
weeks programming the Color Compu
ter and building the interface device.
It is possible to purchase hardwan
and software specially developed fo:
this type of operation. Such a system tc
perform the tasks currently done by th<
Color Computer would cost abou
$30,000. Of course, that does not in-
clude the time necessary to learn how tc
operate the equipment.
So, the next time you show a class i
videotape, or watch something on edu-
cational television, think of the people
behind the production. One of themjusi
might be an extremely creative persor
named Mitch sitting in front of a littk
white computer from Radio Shack.

URN OF THE SCREW
Timing and the SAM Chip
By Tony DiStefano
Rainbow Contributing Editor
A we all know, the CPU in our
/% CJCoCo is the MC6809E. It is
L .m. j^the heart of the computer. It
squires RAM and ROM and I/O and
r ideo and so on to help support it. All
hese devices must be memory mapped,
'hey must appear somewhere in the
4K bytes of memory the CPU can
.ccess. The proper timing and sequenc-
tig must be within the specifications of
he CPU. Normally, a handful of TTL
74 series) logic chips take care of this,
n the CoCo one big chip takes care of
ill of this and more. The chip is the
VIC6883, sometimes known as the
^4LS783N. The name of this chip is a
Synchronous Address Multiplexer or
5AM for short. This is a 40-pin chip
;hat mates the MC6809E and the
MC6847 (the video chip). This chip also
does all of the dynamic memory refresh
Liming and memory mapping of all the
other major chips of the CoCo. As you
san see, this thing is a real workhorse
of a chip. By the time I am finished de-
scribing this chip, everyone will have as
much respect for it as I do.
Tony DiStefano is well-known as an
early specialist in computer hardware
projects. He lives in Laval Ouest, Que-
bec,
The first part of this article is a pinout
of this chip. Figure 1 shows the pinout
of the SAM chip. The following is a pin-
by-pin description of the Motorola chip
number MC6883.
Pin 1 to 4 — All to A8. Address lines
All to A8 respectively from the
MC6809E. These are four of the 16
address lines the SAM requires to fully
control the memory mapping of the
CPU.
Pins 5 and 6 — OSCin and OSCout.
These are the crystal oscillator inputs.
A crystal and supporting components
supply the SAM a master frequency of
14.31818 MHz. This is the highest
frequency available in the CoCo.
Pin 7 — VClk. The first function of this
pin is to generate an output of 3.579545
MHz. This supplies the color carrier for
the VDG (Video Dispay Generator) Clk
pin. The second function resets the
SAM when this pin is pulled to a logic
level of 0, acting as an input. In the
CoCo, this pin is part of the reset
circuitry.
Pin 8 — D AO (Display Address 0). The
function of this pin as described in the
Motorola manual is the least significant
bit of a 16-bit video display address. The
more significant 15-bits are outputs
from an internal 15-bit counter which is
clocked by DAO. The second function,

le CPU.
in 40 — Vcc. This pin requires +5
alts. It powers all the functions in this
lip.
As you can see from these descrip-
ons, the SAM chip and VDG chip are
iOsely linked. The SAM chip generates
ata from its RAM and delivers it to the
DG. That is one of the functions of the
AM. It works closely with the VDG
lonitoring the horizontal and vertical
yncs in order to give it the proper data
lat the VDG later converts to a video
ignal. The SAM has many modes in
/hich it delivers video data to the VDG.
Tiese modes are selected by a set of
egisters in the SAM's memory map.
Jut since the SAM chip has no data
ines going to it, the registers are ac-
essed by writing to odd address loca-
ions to set the register and writing to
ven address locations to clear the
egister. The data written to these
ocations is irrelevant. Table 1 shows all
he SAM control registers and their
unctions. Most of the registers shown
ire used with the VDG.
Pins SO to S2 are used to decode
chunks of memory. These so-called
chunks of memory are what memory
maps the CoCo into what we know it
to be. For instance, BASIC is one chunk
that is 8K long. Disk Extended BASIC
is another chunk that takes up 16K.
These eight chunks are decoded from
the three pins by using a 74LS138. You
might remember this from a past article,
but if you don't, a '138 is a three-input
to eight-output decoder; just what the
doctor ordered. Each one of these eight
outputs controls one chunk of memory.
Table 2 shows all eight chunks and
describes where in the memory map
they appear and what use each has in
the CoCo.
In Table 2, notice that part of S7 are
the SAM control registers. Table 1
describes the SAM control registers.
The SAM control registers are divided
into six areas. The following is a de-
scription of each of these areas.
The first area is the map type. When
cleared, the SAM is in the map type 0.
This is the mode that BASIC sets it up
to be. The ROMs are active and a
maximum of 32K RAM is accessible.
When set, the SAM is in the map type
1 . This mode is better known as the 64K
mode or the RAM mode. In this mode
none of the ROMs are active but all 64K
RAM is accessible. The OS-9 operating
system uses this mode.
The next mode is the memory size.
The SAM can use three types of dy-
namic memory, 4K, 16K and 64K.
When your CoCo is first turned on, a
routine in the BASIC ROM checks to see
what kind of RAM is installed and sets
the SAM chip accordingly.
The third mode is CPU rate. The
SAM has some control as to the speed
at which the CPU can operate. It has
three choices; the first is called slow. In
this mode the CPU runs at .894 MHz.
The next is the dual speed mode. De-
pending on where the CPU is accessing
memory, it can access it at .894 MHz or
at the faster 1.78 MHz. At the dual
speed, SO and S4 are accessed at the
slower speed, all other accesses are at
the higher speed. The third speed is the
fast speed. This is where all accesses are
done at the high speed, but at that
speed, the SAM chip does not have the
time to do video. The video screen
displays garbage.
The fourth mode is the page mode.
When the SAM is in map type 0 and is
using 64K memory chips, only half,
32K, of memory is used. The other half
is just sitting unaccessible. Setting this
register switches in the other half of
memory and switches out the first half.
The fifth mode area is a big one in
that it takes up a lot of room. This is
the display offset. This offset tells the
SAM chip where in memory to start the
video scanning. Since the smallest
memory area the SAM can scan is 512
bytes, all offsets are 512 bytes apart. The
display offset is a binary address to the
start of the video display.
The sixth area is the VDG mode.
Since graphics pages take up more
memory than text, the SAM has to scan
more memory. The amount of memory
scanned depends on the graphics reso-
lution mode required. Basically there
are three amounts of graphics memory.
The first is 1.5K memory, the second is
3K and the highest is 6K. These modes
of graphics must match the graphics
mode the VDG is set to. You will find
more detail on these modes in the BASIC
manual supplied by Radio Shack.
The last mode is reserved for future
use. Who knows what Motorola has in
store for these unused registers.
The SAM chip is a very complex
chip, indeed. I have just described only
the major parts of this chip. Complete
details on this chip are available from
your Motorola dealer. The details I have
given are taken from that manual and
the TRS-80 Color Computer Technical
Reference Manual, available at your
local Radio Shack store.

Resource Development Inc. has give
us some insight into the future of datinj
The firm is predicting that by 199
singles bars around the world will b
equipped with computerized card reac
ers to help their customers meet "coir
patible" companions. According t
Matthijs Moes, who led the study effor
customers will carry special identifies
tion cards — about the same size a
credit cards — and the terminal/ reader
in the bars will read the informatio
into a small computer. The compute
will compare personal attributes an<
indicate to the customer who else in th
bar might have compatible interests
The customer will have to take it fron
there. The cards will give a whole ne\
meaning to the term "personal" compu
ter, says Moes.
On a related note, IRD says medica
cards, similar to the dating cards, wil
be introduced first. These cards wil
contain all-important medical historiei
of the carrier. This information will helf
in processing insurance claims and
more importantly, speed necessar)

HARDWARE PROJECT
With this handy joystick port
switchbox, CoCo can pull off . . .
By Mark Haverstock
The Color Computer owner has a
multitude of control devices to
choose from. Several varieties of
joysticks, trackballs, touchpads and
mice are available to help us draw, play
and create. However, the Color Com-
puter can only accommodate one device
at a time in each of its joystick ports.
Likewise, the hardware component of
the popular graphics program Co Co
Max only offers a single plug-in socket.
If you've ever had to reach behind the
computer to plug and unplug joysticks,
or have wanted to change drawing
devices in Co Co Max, youll appreciate
the Stick Switcher. Armed with a few
parts and tools, you can build this
convenient switchbox for selecting up
to three different devices on one joystick
port. An off positon is also included. It
allows all the control devices to be
disconnected from the joystick port.
Mark Haverstock is an English and
reading teacher for the Boardman
Schools in Youngstown, Ohio, and is
involved in computer and media pro-
jects at the middle school level His
hobbies include computing, photo-
graphy and amateur radio.

This is particularly important for pro-
grams that are adversely affected by
having joysticks plugged in during
operation.
You will need the following parts:
One 6-pin DIN plug, #274-020; three 6-
pin inline DIN jacks, #274-021; an
experimenter box, #270-2301; a two-
pole, six-position switch, #275-1386;
one knob, #274-407; five feet of five-
conductor stranded wire; dry-transfer
lettering; epoxy; and electrical tape or
shrink tubing.
The tools needed include: a drill, 14-
inch and 3 /g-inch drill bits, flat metal file,
small screwdriver, small Phillips screw-
driver, wire strippers, pliers, soldering
iron and solder, and a hacksaw.
Figure 2: Switch
Bend tab back
Construction
First, take the metal cover off the
project box by removing the four Phil-
lips screws at each corner. Mark the
positions of the holes to be drilled on
the plastic bottom of the box (see Figure
1). Then drill these holes using the l A-
inch drill bit. Use the file to remove any
burrs from the inside of the box.
Mark the position of the switch
mounting hole on the metal cover. Drill
this hole using a %-inch drill bit. Again,
remove any burrs from the rear of the
cover. To mark the switch positions on
the box cover, you need to temporarily
install the switch and knob. Prepare the
switch by sawing off all but a half inch
of the shaft. File the rough edges after
cutting. Find the locking tab and bend
it down so it is even with the top surface
of the switch (see Figure 2). Mount this
switch on the metal cover using the
hardware provided and tighten gently
with the pliers. Then attach the knob to
the switch shaft. Rotate the knob,
marking positions 1, 2, 3 and off lightly
on the cover with pencil. After these
have been marked, remove the switch
and knob. Apply the dry-transfer letter-
ing at these positions.
The next step is to wire the cables and
jacks. If five-conductor cable is not
available in your area, substitute five
#22 gauge stranded wires twisted to-
gether, or use the wire from an old
broken joystick. Prepare one 36-inch
and three five-inch cables by removing
one inch of the outer jacket and strip-
ping % inch of insulation from each
individual wire at both ends. Remove
the covers from the jack and plugs and
solder these wires as shown in Figure 3.
Before replacing the covers, be sure to

Match remaining wires from pins 1, 2 and 4.
Twist each group together, solder and insulate
with electrical tape.
inspect the solder connections for
shorts.
Insert the remaining ends of the wires
from the plugs into the three holes in the
rear of the project box and the wire
from the jack into the front. Wire the
switch according to Figure 4. Note that
only two of these lines will be switched:
the +5V and ground lines. The others
will be matched, soldered together and
covered with electrical tape or he*
shrink tubing.
To secure the wires attached to Ji-J
and keep them from pulling out of th
box, apply a small amount of epoxy a
the point where these wires enter th
inside of the box. Allow the epoxy t«
dry thoroughly before going to the next
step.
Fasten the switch to the metal cover
and align the knob with the positions
marked on the metal cover. Be aware
that only the first four positions of the
switch will be used.
Finally, reassemble the box, being
sure to tuck the wires carefully inside.
As a finishing touch, you may want to
cover the dry-transfer letters with clear
nail polish to keep them from rubbing
off. To test, simply plug the switcher
into a joystick port and add your joy-
sticks or other control devices in posi-
tions 1, 2 and 3. You can now enjoy the
convenience of switching without un-
plugging.

HARDWARE PROJECT
Make your deluxe joystick
firebuttons electrically parallel
The
Quick
Joystick
Bruce Goshorn is a U.S. Navy Ord-
nance supervisor and author of several
safety articles in naval publications. His
main interests are Co Co speech and
music synthesis.
By Bruce W. Goshorn
I .C y° u own a Radio Shack deluxe
I I" joystick (Cat. No. 26-3012A)
m m you may have realized that the
black firebutton has no effect when
pressed. A note in the accompanying
manual states as much. With this ex-
tremely simple hardware modification,
you can make it better. All you need is
a Phillips screwdriver and a hot solder-
ing iron. In fifteen minutes you'll have
the versatility of two firebuttons. And
away we go.
Make sure the stick is in the "spring-
loaded to center" position. If not, hold
the joystick in one corner and flip both
black tabs away from the "free" posi-
tions. This disconnects the tabs (and the
joystick bottom) from the rest. With the
bottom facing up, loosen the two screws
with the screwdriver until they ratchet.
Lift the bottom free and place it on the
table with the four feet up. Direct your
attention to the top portion. If you
fumble it and the stick assembly falls
free from the upper part of the case,
don't panic. Keep the assembly together
and slide it back into the slots between
the three black posts.
Place the stick down into a suitable
holder (I used a roll of bathroom tissue)
to steady it. Locate the blue wire and
separate it from the rest by carefully
pulling it up to a gentle loop from cable
end to black firebutton. Measure about
a half inch from where it exits the cable
end and cut it in two. You should end
up with an inch or so attached to the
firebutton. Strip a quarter inch of
insulation from it. Notice the white wire
attached to the red firebutton lug.
Gently pull all other wires away from
this lug so the iron won't melt their
insulation. Unsolder the white wire and
remove any excess solder. Twist the free
end of the one-inch blue wire around the
free end of the white wire when it's cool
and solder these together. Resolder the
lug where the white wire came from and
let it cool. Now solder the white-blue
combination to the lug. Press the other
wires down between the stick assembly
and the black button. Make sure there
are no wires over the post in the corner.
With the cable pointing away from
you, pick up the bottom case and, with
the catalog number away from you and
both X and Y tabs flipped away from
their "free" positions, place the bottom
case on the top part, align and tighten
the two screws. You're ready to test.
Power up the CoCo. At the prompt,
press a few random keys. Press the red
firebutton and try to type. There should
be no response. Release the red button
and press some keys. Letters should
appear. Repeat this procedure with the
black firebutton. Response should be
the same. Incidentally, if the CoCo
won't take input from the keyboard,
you probably have a stuck firebutton.
Unplug the joystick(s) and, if normal
operation returns, replace or repair the
offending joystick.
Your firebuttons are now electrically
parallel. Use the one most convenient
for the particular application.
I've always believed that even the best
things can be better, and this stick is the
best yet. I hope you enjoy your new
hardware.

REPRODUCTION
EARS Does It All!
0&
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 to 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 Get 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

// tafces a skilled boxer to come out
the winner when you're in . . .
By Tim Jones
fter seeing the
new Rocky mov-
ie, I just had to
try and make a
.boxing game for
my CoCo. Finally, after sev-
eral long weeks I came up with
Boxing.
The object of the game is to
gain as many points as possi-
ble, beat all three opponents
and never get knocked down.
When you run the game, the
title screen appears and a short
song is played. The scoreboard
is then presented. This shows
your physical strength as op-
posed to your opponent's. Also
on this screen are the fight and
round numbers and the total
score, which is updated after
every fight.
The game screen is com-
posed of several parts. At the
top your opponent's strength is
represented by a blue bar; your
strength is shown at the bot-
tom. You are the man marked
"U.S.A." At the left of the
screen is a red time bar. When
this bar reaches the bottom,
the round ends.
Move the joystick in the
direction you want to go (with-
out pressing the button). To
punch with the left hand, press
the firebutton. To punch with
the right hand is a little harder.
First move the joystick to the
right, and then press the fire-
button. Since throwing a right
punch is harder, you receive
more points for hitting with it.
Every time you hit with the
left hand, your opponent's
power decreases by 10, your
power increases by five, and
your score increases by five
points. If you hit with the right
hand, his power decreases by
15, yours increases by five, and
your score increases by 10. The
same also goes for him.
Decreasing the opponent's
strength to zero knocks him
down. In order to advance a
fight, either knock him out
completely, or last three
rounds with a score higher
than his.
To knock out the first oppor
nent completely, decrease his
power to zero. To knock out
the second opponent
Tim Jones is a high school student in Clinton, Louisiana. Be enjoys
working with
pletely, you must knock him down twice in one round. To
knock out the third opponent you must have three knock
downs in one round. Note: There is no count after a knock
down, so stay alert!
Game play is rather sluggish, so I have included a POKE
65495,0 in Line 130. If your computer can't use it, just
delete that line. As you can see, the game is long; buying
rainbow ON tape can save hours of debugging. Enjoy! □

REVIEWING
Color LISP
Editor:
I must take exception with Mr. Dooman's
software review of Color LISP in the May
1986 rainbow. Mr. Dooman compares LISP
to both forth and basic. These are numer-
ical languages, basic is a good general
purpose, data-processing programming
language. FORTH is an extendable, fast
interactive, compiled, stack-oriented con-
trol language, lisp is a symbolic manipula-
tion language, extendable by user defini-
tions.
Mr. Dooman complains about the docu-
mentation using brackets instead of paren-
theses. The documentation does not contain
brackets in the examples — parentheses are
used in all examples and all examples have
been tested to ensure they function as
described. Not one of our many customers
have complained about "brackets."
As Mr. Dooman pointed out, there are no
standards in lisp function syntax. In our
implementation, the syntax of M APCAR is:
MAPCAR/ list/function. In some other
LlSPs the syntax is: MAPCAR/function/
list. The syntax can easily be changed to
reverse the arguments simply by defining a
new function such as: (DE MAPC (fns lis)
(MAPCAR lis fns)). All examples in the
documentation have been fully tested. The
snytax is clearly stated with ample examples
to illustrate the proper use. Also the com-
plete function definitions are provided.
Mr. Dooman mentions none of the fea-
tures of this implementation for the Color
Computer such as: low resolution graphics,
integrated into architecture of the Color
Computer, joystick, sound, cassette func-
tions, disk functions, printing, PEEK, POKE,
USR, firebutton, break, load and save lisp
objects, load and save lisp work spaces, and
long error messages. This implementation
was especially designed to take advantage of
the limited resources of the Color Computer.
The stack and node area can be redefined to
explore different areas of interest. EXPRs,
FEXPRs, and machine language subrou-
tines are supported.
Though lisp is an interactive language,
this implementation has been optimized for
both speed and size. We feel we have a good
and reliable product which enables CoCo
owners to experiment with a language used
extensively in artificial intelligence. Our goal
was to provide a powerful, flexible, extend-
able and reasonably priced software pro-
duct.

Super RAMdisk
Editor:
Thank you for reviewing the DISTO
Super RAMdisk and giving it a fair shake
[June 1986]. I would like to inform you that
a "hardware" user's manual is now available.
The OS-9 software and documentation has
been upgraded to V2.0. Anyone who has a
print spooler, or any other utility for my
RAMdisk may contact CRC Inc., 10802
Lajeunesse, Montreal, Quebec, Canada for
more details.

DISTO
DeskMate
Editor:
In Mr. White's review of DeskMate for
the CoCo in the May 1986 RAINBOW, he
mentioned that the Calendar utility was not
useful beyond 1999. If he were to enter his
data as 4/25/2000 instead of 4/25/00 (which
defaults to 1900), he would find the correct
date in the correct year. You can use years
as late as 9999.

TX Word Processor
Editor:
I am comparably new to the computer. I
got started with the CoCo in August 1985
and ordered rainbow at that time.
Since I had purchased the CoCo primarily
for word processing, the TX Word Proces-
sor in "Received and Certified" (November
1985, Page 188) caught my attention. I
ordered it and, while waiting, I went to work
on Color Scripsit as it came with the com-
puter. After TXcame, I made a quick change
and found it so much better in every way.
After your review that found TX juvenile
[March 1986, Page 209], I tried still another
word processor, but it too was difficult to
run and had very poor documentation, so I
went back to TX Version 01.08P. I feel your
reviewer was over-educated for the job and
I think the readers are getting shortchanged
because of the review.
This is being written using TX, and it is
still my favorite. I would like to see another
review, preferably by an operator instead of
a programmer. There are a lot of us out here
who are beginners.

The Best Epson
Screen Dump Utility
Editor:
My program, The Best Epson Screen
Dump Utility , was reviewed by R.W. Odlin
in a recent issue [February 1986, Page 216].
My thanks to your reviewer for taking the
time to carefully test the program.
However, one comment in the review has
left me scratching my head — that is the
matter of pixels being swapped from left to
right with Graphicom screens. The reviewer
did not contact me regarding this problem,
and I don't understand how it could happen.
The sample printouts on the package are of
Graphicom screens, and they certainly do
not exhibit this problem.
I have no idea how Mr. Odlin loaded the
Graphicom screens into memory, but if the
GOBIN utility (included with Graphicom)
is used, I can assure your readers they will
have no problem printing out pictures with
The Best Epson Screen Dump Utility.

Software Review*
Pinball Factory
Rings Up Points
I've never been a big fan of computer pinball — until now.
I've tried practically every CoCo pinball game on the
market, and while most of them have been good, after a
few games I would invariably become bored. After all, these
games only offer the choice of a few playing fields, and even
the most diehard pinball fan is sure to soon tire of playing
the same game over and over and over.
Enter Pinball Factory from MichTron, a terrific new
game which not only lets you play pinball on your CoCo,
but lets you create your very own pinball game. Pinball
Factory is similar to Pinball Construction Set on the Apple,
and it puts new life into a very old game.
Pinball Factory comes on disk and is accompanied by a
set of easy-to-read, complete instructions. I was glad to see
that the disk was not copy protected and was accompanied
by instructions on making a backup disk for your own use.
Loading the game is as simple as putting the disk in the drive
and typing RUN "PINBRLL". After the title page appears,
you have the option of playing the current game, loading
a new game from disk (eight sample games come on the
disk), modifying the current game or creating a new one,
saving your creation to disk, or taking a directory of the
pinball files on the disk. The program requires only one
drive, but can use a second drive if you have one.
Load a game by moving the on-screen pointer with
keyboard, mouse or joystick to the section of the screen
marked LORD and press ENTER (or the joystick button) then
point to the file you want to load and press ENTER again.
There is no need to type in the filename from the keyboard.
Because the pinball data files are stored in a special format,
they do not appear on the disk directory, and the manual
warns not to save any other files on your pinball diskette.
Once loaded, selecting Play from the screen lets you play
the current pinball game. You then have control of the two
flippers and can "tilt" the board in one of three directions
(left, right and up) to make the ball go where you want it.
The graphics are in black and white only, but are quite good
nonetheless. The animation is good and, except for a few
rare moments, flicker-free. Sound effects are adequate, but
not diverse. Pause and Quit options are provided.
The area in which Pinball Factory shines is in the creation
and modification of your own pinball games. You can
control the placement of everything except the flippers; you
can even design your own high-resolution graphics logo for
your pinball game. You can place bumpers of varying types
around the board. When the ball hits one of these, you score
a certain number of points — it is up to you how many
points each type of bumper is worth, as well as how many
points it takes to earn extra balls — and your ball is
deflected back at a fast speed. There are even "multirail"
bumpers which provide bonus points if all rails are hit.
Pinball Factory also allows you to place polygons anywhere
on the board. These polygons act only as physical obstruc-
tions, yielding no points and hindering the balls. They may
be used to change the shape of the playing board or increase
the challenge. Once placed, any object on the board can be
removed or changed, and the program provides a test option
for trying out your creation. Up to 90 objects may be put
on the playing field.
Once the playing field is set up, you can change the rule!
of the game. This includes setting the speed, the pull o:
gravity on the ball, the number of balls, and the elasticity
(which controls how fast the ball will bounce off ar
obstruction). As I mentioned before, you can also change
the scoring rules, thus making the games harder or easier.
Overall, this is an excellent game. Unlike past pinbaL
games, Pinball Factory puts you in control of the entire
pinball game, letting you tailor games to your particulai
liking. You can even design pinball games with friends and
have a pinball marathon or competition. Because Pinball
Factory does not lock you into a particular game, it kept
my interest, as I'm sure it will yours. The only minor bug
I found was that the selection (menu) pointer scrolls off the
screen in one direction but not the other, which was
sometimes annoying, but doesn't affect game design or play.
Suggestions? MichTron could have included more
features to build a pinball game from, such as ramps,
optional flippers, moving targets, etc., or a feature to let the
user design his own bumpers or polygons. Letting the user
create his own sound effects or background music would
have put the icing on the cake, but Pinball Factory is a most
enjoyable game as it now stands.
On a scale of one to five, I would rate Pinball Factory
as follows: playability, 5; sound effects, 3; keeps interest,
4; price vs. value, 3; graphics, 4; speed/ animation, 4;
documentation, 4; and overall rating, 4.
As a final note, I was impressed by the trust MichTron
puts in their customers. Not only was the game able to be
backed up, but MichTron offers a guarantee of satisfaction
and a 30-day warranty. If you even remotely like pinball,
I think you can trust that you'll enjoy Pinball Factory.

oftware Reviewi
Darkmoor Hold: A Valuable
Software Library Addition
Wandering through the dirnly-lit corridors of a myste-
rious castle in search of adventure and riches is a daydream
many of us romantics share. Until the CoCo came along,
dreaming and reading were the extent of my fantasies. Now
with software such as Darkmoor Hold, by Prickly-Pear, I
san finally wander to my heart's content.
Darkmoor Hold is a graphics Adventure/ Simulation that
puts you, a human mercenary, in charge of a trio of
adventurers hired by the ruler of a troubled kingdom. It
seems an evil wizard is killing the king's beloved taxpayers
and he would like you to remedy the situation. The wizard's
castle, Darkmoor Hold, is comprised of 10 levels, each
consisting of 20-plus rooms. You must survive all 10 levels
while gathering better armament and treasure on the way.
Since I was only able to get to level six, I can't testify as
to what happens when you finally reach the wizard on the
10th level.
Darkmoor Hold has a different format than most
Adventures on the market. In fact, it may be closer to a
fantasy Simulation than an Adventure. The screen has the
appearance of an ancient parchment scroll and is split into
several parts. The top one-third shows a 3-D graphics
representation of the rooms and corridors through which
you wander. The bottom two-thirds is divided into three
columns, allowing you to enter commands for each of the
three adventurers. You, the human, a small but powerful
Dwarf and a magical Elf make up the trio. The commands
you can enter are predefined and consist of just under 20
choices. Examples are directions, search to find objects,
fight to defend yourself and inventory. As my combat
experience proved, 80 percent of the time you will find
Two-Liner Contest Winner ...
This one allows you to enter the number of options
on your gameboard's spinner. Then it will randomly
select one. It might even eliminate those spats about
how you "accidentally" bumped the spinner to alter
the outcome.

yourself entering fight. To call this game a slugfest would
be putting it mildly. While I'm sure there are strategies to
be developed, most of the time it's hard enough just staying
alive.
Traveling through the various levels you face creatures
of increasing power. On each level all the creatures look the
same and only the Elf can correctly identify them. The
graphics for the rooms and creatures are all very well-done
and add considerably to the enjoyment of the game. In
addition, for those of you who find spare time hard to come
by, the game has a SAVE and LOAD feature allowing you to
explore a little at a time.
The program is not copy protected, has a guaranteed free
replacement for as long as you own it and is supported by
some of the most considerate people I have ever done
business with. There are many good companies selling
CoCo software today and I can testify, without hesitation,
that Prickly-Pear is one of the leaders.
I liked the program and would recommend it to any
fantasy buff. I do feel, however, that the more experienced
adventurers and role players out there might find the
challenge a little too limited for their tastes. On the other
hand, inexperienced adventurers who want a sample of
Dungeon exploring, would do well to consider this program
for their library.

Wizard's Castle — Great for
Novices and Pros Alike
If you remember those Saturday afternoons when you lay
in front of the TV and watched the Good Guys save the
Princess, you have the premise of Wizard's Castle in a nut-
shell. Don't let me fool you into thinking that it will be quite
as easy as that, however. This is a very pleasantly frustrating
game.
Wizard's Castle, a graphics Adventure game, comes with
excellent documentation. It includes a list of verbs and
nouns to use in playing the game. It also covers the creatures
you have to kill in order to save the Princess. Remember
the descriptions of these creatures or you may try to kill
one that just might help you.
One of the frustrating things that makes this game hard
is not only do you have to kill the creatures, but just when
you think everything is fine, the wizard brings them back
to life. Even if you manage to hack the wizard to death,
he can come back to life, too. Some of the creatures, like
the Ore, follow you around. Others, like the Gnome, will
just take all your coins, laugh and leave.
One of the saving graces is the "eerie glow;" just when
you think you're going to die, it surrounds you, rejuvenates
you, and the game goes on. The game also includes a help
function which, if you ask the right question, will give you
clues. To keep it interesting the author used riddles for the
clues.
The help you receive is dependent upon your status in
the game. There are three variables in Wizard's Castle:
condition, score and experience. Condition is your physical
strength and varies with how many dragons you've fought
and how well you've done. In wandering around the
kingdom you may find apples to eat or water to drink and
they will boost your condition. And if you get lucky, the
eerie glow will surround you and really give a push.
During your travels you find any of 24 different objects.
If you can manage to get these back to the King, you are
awarded points (either as score or experience, or both).
Experience points can also be earned by actions like killing
your enemies. Experience points are needed to be able to
do some of the actions in the game. But, with more
experience, you fall into more traps. You have the option
of trading score for experience. The only thing I could not
understand from the documentation was what the score
points were for except buying experience.
There are three levels of play. In level one the creatures
are a little easier to kill, points are easier to earn and it just
seems you are luckier. Level three is hard; even moving
through the game drains some of your strength away. The
creatures are harder to kill, they're trickier, and traps pop
up more often. The documentation states that level three
should take about eight hours (or more) to play. The game
is in real time, so even if you don't see a cyclops waiting
when the screen comes up, don't sit still too long or he may
come after you.
There are several nice features with this game, such as
the Freeze command. To stop and think, you can enter
FREEZE and the game is on hold until you want to play some
more. You can also save the game you're playing onto the
game disk to be able to pick up where you left off. Wizard's
Castle will talk to you if you have a Radio Shack Sound/
Speech Cartridge, but I didn't think it helped much (at least,
it didn't tell me how to win). To quit, type UNCLE, and you
can start all over.
Even though / never saved the Princess, I believe you will
find Wizard's Castle well worth the money no matter what
your level of expertise with Adventures. It is easy enough
for those of us who play just for relaxation; and difficult
enough for the die-hards who think they can master
anything.

Disk Directory Printout
If you have a long disk directory and want to see
all of it, or if you simply wish to have a hard copy
printout of your directory, one simple command
allows you to do this easily.
Just POKE 111,254:DIR and the entire disk
directory will appear on your printer, even if it is too
long to be fully displayed on the screen.

Rescue Your Disks
with Salvdisk
Salvdisk (salvage disk) is a machine language utility for
salvaging information from a damaged disk. It may be used
with files consisting of BASIC, machine language programs
or data. Using Salvdisk, you can copy one granule at a time
to either another disk or a different granule on the same
disk. After moving a file, you can modify the disk directory
to use the data in its new location. Salvdisk requires a Color
Computer with a disk drive and 32K of memory.
Salvdisk is supplied on a disk without the usual instruc-
tions. (But instructions are provided.) After doing the
machine language LDADM "SALVDISK" and EXECuting, a
title page (with copyright notice) appears. At this point,
press any key to continue. The second screen asks whether
you desire written instructions. If you respond with a 'Y',
the program allows you to select the Baud rate, and the
instructions are sent to the printer. If you're familiar with
the program, this can be bypassed by responding with an
4 N\
Having entered the main part of the program, you are
given a choice to Load Granule, See Granule, Dump
Granule, Alter Directory or Return to BASIC.
Load Granule reads the specified granule's contents into
CoCo's memory. (Granules one through 68 store files;
granules 69 and 70 comprise the directory.)
See Granule displays the contents of a previously loaded
granule one sector (256 bytes) at a time. The display,
however, is generally illegible — showing primarily graphics
patterns and an occasional identifiable character.
Dump Granule allows you to write a previously loaded
granule into a new granule of your choice. You may want
to write it to the same granule number on another
(undamaged) disk, or write it to an unused granule on the
damaged disk.
Alter Directory allows you to update the directory after
moving a granule (or granules) around. Without this step,
the computer would not know where to look for the
relocated file.
Return to BASIC allows you to test modifications without
having to turn off the computer and accessories. This is
convenient because a test file (called "try it") is created when
you modify the directory. By using EXEC, RUN or read, you
can confirm the correctness of your work.
Being a relative newcomer to the world of disks, I have
not (yet) crashed a disk. But I know it's just a matter of
time, so I welcomed the opportunity to review this program.
Unfortunately, 1 was disappointed. In order to use Salvdisk,
it is imperative to be able to identify the granules associated
with each file. This task would be easy if I could use the
program to read the contents of each sector and granule,
but the resulting display when 1 "view" the granule is
predominately graphics patterns with only rarely identifi-
able characters.
I tried this program with both binary and ASCII files
without success. I called the author to discuss my difficulty,
and he explained that this was normal. He also explained
that determining the granules that contain a program is
accomplished through trial and error. And to further
complicate the salvage procedure, the granules must be
relocated in correct order, while the order on the damaged
disk is not necessarily consecutive — the granules compris-
ing a program may be numbers 34, 35, 50 and 26. When
salvaging these, they must be relocated in the correct
sequence. In other words, I have to write granule 34 first,
then 35, then 50, then 26 to consecutive granules on the new
disk — 10, 11, 12 and 13, for example. And, the correct
order can only be determined through trial and error.
I also tried, unsuccessfully, to identify the starting granule
of the test program by reading the directory (using the read
granule activity on granules 69 and 70, as specified in the
instructions).
The two pages of instructions are neither complete nor
well-written, but are sufficient to experiment with the
program.
In summary, attempting to use this program reinforces
the necessity of making frequent backups of critical disks.
The distribution of Salvdisk is unique, in that the author
has not set a price; rather, he will send you a copy of the
program if you send him a formatted disk. When you
execute the program, one of the opening screens explains
that the author would appreciate a donation if you find
Salvdisk useful.

Action-Packed Rommel 3-D
Requires Practice
With anxious hands, you hold the controls of your death
machine in hopes of finding the enemy. The mission appears
simple, but you know in your heart that this will be one
of the harder missions you face.
Rommel 3-D is a game of speed and skill. You have a
tank that must seek and destroy other tanks and planes
trying to destroy you. As you destroy them, you receive
points and if you gain enough points you receive bonus
tanks. The challenge is to develop a strategy that enables
you to increase your scores constantly.
A joystick is not needed to run the game. Use the arrows,
or the T', 'L\ 4 W or *Q f keys to move and the space bar
to fire the cannon. Scoring is accomplished by directly
hitting the enemy tanks or planes. Points are given for
hitting three different things: dumb tanks worth 1000
points, smart tanks worth 1500 points and planes worth
1300 points. You receive one bonus tank for every 10,000
points you get until 100,000 points after which it takes
20,000 points to get a bonus tank. On the screen you see
flat land with mountains on the horizon. Scattered around
this land are various obstacles you cannot move through.
The enemy vehicles are three-dimensional tanks or airplanes
in various colors. In the middle of the screen are the sights
for your tank. They become smaller when an enemy tank
or plane is in firing range. In the upper right hand corner
there is a radar screen. Your tank is the center of that screen
with other vehicles appearing as blips in relative position
to you.
The only way to win at this game is to practice. If you
get in trouble, move your tank backwards and to the left
or right very fast and maybe you won't get hit. The only
strategy that worked for to me was to keep moving.
When I played this game I got killed very fast at the
beginning, but as I played I did get better slowly. The game
is a challenge, fast moving and fun. If you are into action-
packed war games then this game is worth looking at.

Clever Animation in
Adventure in Mythology
Fans of graphics Adventure games will enjoy Saguaro
oftware's new game, Adventure In Mythology. The 64K
lachine-Ianguage game is available on tape or disk. The
isk can be backed up, but the backup copy will not run.
>n loading the backup copy, you get a message that says
le files can be recopied to the original disk if necessary.
The game does not load from JDOS or from the disk
ersion of ADOS. I had no problem with DECB 1.0.
according to the instruction sheet, the game can be used
/ith the Tandy SSC Speech Sound Pak. But even without
lat accessory, the game is not totally silent — there are
its of music and sound effects built in.
Adventure In Mythology comes in a simple, yet most
ttractive package. The instructions are short and to the
toint.
The graphics are cleverly animated. For example, when
ou are in a rain forest, you can actually see the rain coming
lown. If you have a key to open the castle door, you see
t open up.
As the name of the game implies, the Adventure is based
>n the popular tales of ancient mythology. Among the
iharacters you encounter are King Minos, Ariadne, Icarus
tnd Galatea, just to name a few. "Your goal," we are told,
Is to win the hand of the beautiful Atalanta, the swift-
unning huntress." I never got to meet her, though, because
kept getting mugged by bandits, trapped in inescapable
ooms, drowned in the ocean and tripped up in the darkness
)f the famous Labyrinth.
Like other games of this type, Adventures In Mythology
:an take many hours to play, so youll find the ability to
iave a game in progress and reload it later very handy. The
iisk actually allows ten different saves — so you can save
one game at several landmarks along the way. Then if you
get killed, you can go back to any of those saved points and
try again from that point.

What's Your ROM Version?
With all the talk about new ROMs, you may be
wondering exactly which ROM you have. If you have
an older CoCo with Extended BASIC, just read the
version number of your Extended BASIC at the top of
the screen on power up. Then, to see which Color
BASIC ROM you have, type EXEC 41175 and press
ENTER.
If you have the new ROMs, Extended BASIC will
be Version LI and Color basic will be Version L2.
On the CoCo 2, Color BASIC will always be Version
1.2 or 1.3 (which are functionally identical).

Software Review ^S^SH^S^^^
Take a Chance — Play S kance
Do you like games of chance such as Yahtzee or dice? Dc
you like to go one-on-one with your computer and
sometimes win? If so, you're a likely candidate for Skance.
The program is written entirely in BASIC and requires a
16K CoCo with Extended Color BASIC.
When I ran the program, the instructions were simple and
straightforward. Besides the instruction screen, there are
four other screens you will use: The Player Screen lists all
of the players, the Score Screen shows the current scores,
the Dice Screen shows the dice being rolled and the Winner
Screen gives the winner's name and score.
After the instructions, you are asked how many people
will be playing. Up to four people can play or you can play
against the computer.
The object of the game is to score as many points as
possible. To score, you need to stop rolling the dice before
your point number comes up a second time. Your point
number is the first number you rolled.
The game consists of seven rounds of play. After the
seventh round, the winner's screen comes up and displays
the winner's name and score. Although the computer keeps
track of all players' scores and who is playing, once a player
begins rolling the dice, there is nothing displayed on the
screen to tell the players who is rolling. We found this to
be a problem.
After you decide how many people are going to play, the
screen indicates whose turn it is. There are two options:
press the 'A' to roll the dice or press the 'S' to see the current
scores. If the 'A' is pressed, a screen comes up showing two
dice. After each roll, you are given three choices: roll again,
see score, or next player. These are chosen with the 'A', 'S'
and 'N' keys. If any other key is pressed, your turn ends
and the next player is up.
This game requires no skill to play, but if you like games
of chance, this may be for you.

Software Review SS^SSSS^SS^SSS^\
Portraits of Christ Presents
the Gospel of John
Get out your copy of 2010 by Arthur C. Clarke and youU
;ee in the introduction he reveals that the entire text of this
lovel was mailed from Sri Lanka to New York on a single
iiskette. He was heralding the arrival of the age of
:echnology. Now, in the same tradition, is the book I
received for review from Sovereign Grace Software,
Portraits of Christ.
Two CoCo-formatted diskettes contain ASCII text files
which can be loaded by your word processor and read on-
screen or printed out. Both the documentation and an
introductory file explain the screen and printer formatting
necessary for proper hyphenation and paging. Using
Telewriter, all files loaded without a hitch. Following the
formatting parameters produced a well-organized screen
layout of 63 characters per line and a printout properly
paged and aligned. (A call to the author, Pastor Mark
Camp, indicated that the disks now contain a program
APrint, that can be run to get a hardcopy without a word
processor of your own.) There are 21 chapters plus a title
page and disk information file.
The book is essentially a discussion of the New Testament
Gospel of John. It presents the idea that a unique aspect
of Jesus Christ is emphasized in each chapter of John.
Sample titles include "Jesus Christ — Consoler" and "Jesus
Christ — King."
In the 1 5th century, the Spanish mystic Fray Luis de Leon
published a work called Los Nombres de Dios (The Names
of God) which approached the idea with the same method
for the entire Bible. But Portraits of Christ is not just a
theological discussion. The nature of Portraits of Christ can
be accurately described as fundamental Christianity. Its
stated purpose is evangelical.
I got the feeling that each chapter may have originally
been a sermon delivered by its author. Each chapter
concludes by directly addressing the reader to encourage a
decision of a spiritual nature.
To sum up this offering by Sovereign Grace Software
without bias, it is a literate, well-prepared presentation of
the Gospel of John written for the purpose of teaching about
the nature of Jesus Christ from a perspective of evangelical,
Protestant Christianity.
Pastor Camp told me that he would like $10 for the two-
disk set but admitted he is willing to accept donations of
any amount as well. He is, not surprisingly, more interested
in spreading the word than reaping profit.

Software Review^
Check out Computer and
Business Bankbook
By Neil Parks
Sunrise Software has two new programs available that
not only serve as check registers, but also print checks. If
you pay the same creditors every month, this could prove
to be a real work saver.
Computer Bankbook is designed for home users. Busi-
ness Bankbook — available in two versions — is a similar
program designed for business users. Both programs are 100
percent BASIC and come on disks that can be backed up.
Both come with a "code plug." This bit of hardware plugs
into the right joystick port, and without it the program is
unable to run.
Since Computer Bankbook is a BASIC program with no
machine code, it should be compatible with all operating
systems, but it isn't. The disk I tested appeared to run
properly under JDOS, but certain data fields, which I
wanted to leave empty (as permitted by the program), were
filled with random garbage. Attempts to edit the data via
the program's edit routine resulted in various crashes and/
or loss of entries.

I had no problems with DECB 1.0 or the disk versioi
of ADOS, so I presume that the problem with JDOS i
caused by differences in direct-access disk formatting, bu
I don't know. Copying the program to a JDOS-formatte<
disk did not help.
The program ends by cold-starting the computer (POKE
113,0: EXEC 40999). With the disk version of ADOS, there
is garbage on the screen, but pressing the Reset button
restores the built-in DOS. Computer Bankbook is a natural
for ADOS's RSV high-resolution text screen — or would
be, but for some superfluous semicolons which should be
removed from the menu-printing routines. The Edit screens
actually work much better with RSV than they do with the
regular 32-by-16 display.
The eight-page manual is well-written and easy to
understand, though a couple of points were left out that
probably should have been mentioned.
The first step in setting up the check register is to enter
a beginning balance. Although there are only seven items
on the main menu, the beginning balance is selected by
pressing '8'. That was probably done because, after entering
the balance, you won't use that routine again for a year.
There are two ways to enter checks. If you are going to
have the computer print your checks, you use the Check
Printer routine. When each check is printed, it is automat-
ically entered into the register. For creditors you pay on a
regular basis, enter their names and addresses into a file.
Then every time you want to send a check to one of those
creditors, you call up that file. Enter the last check number
used, and the check or checks printed are properly
numbered.
There is also the option of special checks, for which the
name and address of the payee is not stored in the file.
The second method of entering checks in the register is
also the method for entering deposits — the Add Checks/
Deposits Manually selection. The manual suggests that you
may wish to use the Check Printer routine in preference over
the Add Manually option even if you don't plan to have
the computer print your checks. Personally, I disagree. I
found the Add Manually option much easier to use.
(The manual says that if you wish to use the Check Printer
routine without actually printing checks, you must change
one line from a GDSLIB to a REM. What they forgot to mention
is that this change affects only the regular checks, not the
special ones.)
Although the manual doesn't make it clear, all checks and
deposits must be entered with a two-digit month. For
example, January 25 has to be 01/25, not 1/25. If you enter
the month with only one digit, the entry is accepted, and
the check is printed properly. But the routine that prints out
the transactions for a particular month keys on those two
digits, so any entry with a one-digit month is omitted from
the listing.
The day can go either way — 12/4 and 12/04 are equally
acceptable. The year is optional. Although the Computer
Bankbook manual doesn't expressly say so, it becomes
obvious that one year is the maximum length for the file,
because the printout for one month doesn't key on the year.
All entries for a given month must be consecutive.
Otherwise, the balance column in the printout for that
month will look strange. This may cause a slight problem
if you write a lot of checks early in the month, before you
get your statement and find out how much interest you
1 44 THE RAINBOW August 1 986
arned for the preceding month. But you can always date
he interest deposit as of the first of the new month to get
jound that. Again, this is a point that should have been
nentioned in the manual but wasn't.
Each check is considered to be outstanding until you
ndicate, either on entry or editing, that it should be canceled
cleared). When you get your monthly statement from the
>ank, just print out a list of outstanding checks. A total will
>e printed with it. Add that total to the present balance and,
f it agrees with the bank's balance, you've made balancing
'our checkbook quick and easy. (Deposits are considered
canceled on entry, but you can always edit one to outstand-
ng if it occurred too recently to be on the bank statement.)
Each check and deposit may be assigned an account
lumber. Here's where the program really proves its value,
ifou can print out a list of transactions for each account
lumber, for any one month or for the entire file, and the
ist will be automatically totaled. For example, let's say all
/our checks for charitable organizations are assigned to
iccount 18. Tax time comes and you want a total of
charitable contributions — it's as easy as printing out
iccount 18 for the year. For this feature alone, Computer
Bankbook is well worth twenty bucks.
There are a few quibbles, albeit minor ones. Author
James Goldsberry did not make allowances for writing a
check larger than $999.99. The program can handle it, but
the printout looks strange because it exceeds the "print
using" format. (Four-figure deposits and balances look
OK.)
There is a slight inconsistency in those routines that
require a Y/N response. In some of them, the ENTER key
is interpreted as Yes, in others as No, and in yet others as
no response. Obviously the third situation is the most
desirable and should have applied in all cases.
When you enter the beginning balance (via menu option
8), I suggest you enter the amount as zero. Then, as your
first transaction, post a deposit in the amount of the
balance. Use the edit function to change the name from
"deposit" to "beginning balance" or "balance forward" or
whatever. That way, if you ever need to recall the file for
a prior year, you don't have to make any adjustment to the
beginning balance. This method lets you use the same disk
for more than one checking account at the same time —
your personal account, your spouse's account, a joint
account, etc. When you finish working with each account,
just copy the CHECKS . INF file to a library disk under the
name of your choice, and recall the one wanted by killing
CHECKS. INF on the system disk and copying the appro-
priate file in its place. You can have several years for several
accounts stored on one library disk. That makes more sense
to me than creating a new system disk for each account file,
as the standard procedure would require.
Business Bankbook is essentially the same program, with
a few added features. The main difference is that instead
of assigning each transaction to one account, you can assign
up to four accounts. So if an invoice includes merchandise
cost, freight and tax, for example, each of these components
can be posted to its own account. Enter the amount for each
account, and the total is calculated automatically.
Business Bankbook comes in two different versions.
System I (also known as Bank 7. 1 or 7.3) uses one disk drive.
System II (alias Bank 9.1 or 9.3) assumes two drives — one
for the system disk and one for data storage. The beginning
balance entry appears on the menu in Business Bankbook,
but works the same as in Computer Bankbook. (With
System II, my alternative method of the zero beginning
balance becomes even more useful: You don't even have to
kill and copy files to go from one to another. Just rename
the appropriate file on the data disk to or from CHECKS
-INF.)
The 10-page manual for Business Bankbook was appar-
ently written some time after the other one, because it does
mention that each file should contain one fiscal year, and
it does not suggest using the check printer routine to enter
checks without printing them.
I did not test Business Bankbook under the non-Tandy
operating systems, but since the two programs use similar
direct-access disk I/O routines, I would expect the results
of such a test to be the same as they were for Computer
Bankbook.
Business Bankbook allows you to enter a table of Active
Accounts, consisting of any account numbers you regularly
use, and a name for each account. This chart can be printed
out at any time, and will appear in numerical order even
if you didn't enter them in order. Also, the account names
in the table appear on the check vouchers.
Unfortunately, there are two bugs in this routine. In the
Edit mode, you are asked if you want to change the account
number or account name. But any change in the account
name erroneously produces a random change in the
number, and any attempt to change the number fails. Also,
if you use an account number that is not in the table, the
check printing routine puts an inappropriate name in
instead of a blank space. There is one line on the System
I program that says RUN BANK -10. However, BANK. 10 is
a file which occurs only in System II. Somebody didn't
debug as thoroughly as he should have.
On the plus side, by the time Business Bankbook was
written, Mr. Goldsberry corrected the inconsistency in his
Y/N routines, so that only a 'Y' or an 'N' would be accepted
as a response.
Business Bankbook also has a routine called Convert that
allows you to convert your Computer Bankbook files to the
Business Bankbook format if you want to upgrade. The
Business Bankbook manual says that a Computer Bank-
book file of about 300 records takes seven granules of disk
space. After conversion to the Business Bankbook format,
the same data occupies eleven grans.
The manuals for both Computer Bankbook and Business
Bankbook state that the check printing routines are
expressly designed for use with Nebs Computer Forms
tractor feed checks #9025-1, and that Line Printer VII,
DMP-100, and possibly other inexpensive printers can't
handle such heavy paper.
With each program comes a checklist to fill out and send
in if you have occasion to write to Sunrise Software. "Please
outline the problem you encountered in as much detail as
possible," says Sunrise. "We will do all we can to help you
solve it." I like that.

Hardware PA,/,VfclJ/M —
New Modem Pak
is ^Interesting'
The new Modem Pak from Radio Shack is quite an
interesting piece of equipment. As a hardware item it
exhibits a concept that is very useful to the Color Computer
user. Imagine, a modem you just plug into your CoCo's
cartridge port.
Those who have learned the hard way and upgraded from
Commodore to the CoCo may remember the old Vic
modem. This new modem from Tandy goes a bit further
than that one, though. The old Vic modem required the use
of a tone capable telephone with a removable handset. The
Modem Pak works with either a tone or rotary line and is
direct-connect. Just plug the modem into the phone outlet
and dial the number with your family phone.
The Modem Pak is a good, basic telecommunications
package all wrapped into one small plastic case. It includes
the interface to its internal 300 Baud modem via a 6551
ACIA. It also includes communications software in ROM.
The Modem Pak is very easy to operate. If you are using
the Multi-Pak Interface, you can put the Modem Pak in slot
one, two or three, and then set the selector for the
appropriate slot. If you are not using the MPI, just plug
the Pak right into the side of the CoCo. Then plug the unit
into the phone line, type EXEC &HC000 and you are ready
to go. A menu of options appears on the screen. If you press
the space bar, a second menu appears. Press it again to
return to the first menu.
Several options are included in addition to the standard
parameter options. Besides being able to alter the standard
communications parameters, you can adjust the printer
Baud rate, Xmodem timeout, cassette and printer buffer
sizes, and turn the ASCII filter on or off.
The internal software lets you switch the printer Baud rate
between 600 and 1200 Baud. Unfortunately, it does not
allow you to go any higher than this. My printer likes to
operate at 9600 Baud.
The Modem Pak does allow the use of the Xmodem
protocol for file transfer. However, any files to be transmit-
ted must be in ASCII format. Also, there is no provision
for the user to supply addresses if he or she wishes to save
a machine-language program from the buffer to a tape. I
found this implementation of Xmodem to be very awkward,
primitive and limited. It would still be advisable for users
of this product to transfer files using the ASCII transfer
method, which seems to be pretty reliable.
The ASCII filter option is very useful. When this optic
is turned on, all control characters are stripped from tl
transmitted data. Any characters over 80 Hex are filter*
out. If you want to transmit data containing graphics codi
or special key codes, just set this option to "off."
A very interesting feature of the Modem Pak is its "dua
combined" buffer. When communicating, there are tw
buffers; a cassette buffer for data you may want to save an
a printer buffer for sending data to the printer. The tot
combined buffer space may not be more than 28K, but yo
can use any configuration of cassette and printer buffer size
not exceeding this limit. I found that, under most circuir
stances, a printer buffer size of IK is more than enougl
The only time data stays in this buffer is if the printer i
offline. Otherwise, if the printer function is turned on, a
received data is immediately sent to the printer as well a
the screen. This is great for getting a hard copy while onlint
With the cassette buffer, you may save or load data t
or from tape, clear the buffer, or view its contents. Thes
features are very useful additions to transmitting data fror
or receiving data into the buffer. They will benefit mos
users.
A feature that will benefit CoCo owners with *B' revisioi
CoCo 2s is the true lowercase option. If your CoCo is se
up to use the new VDG Tandy has been using, the Moden
Pak can recognize this and be set so that you get true lower
case during communications.
One thing I thought was poor was the lack of suppor
for disk systems. As it stands, the Modem Pak works onl]
with tape-based systems. This is because the software ii
ROM makes it very difficult to work with the disk. The uni
is set up so it can operate under OS-9 version 2.00.00
provided you have the Ml or M2 driver and the appropriate
descriptor installed. In this case, it will work with a disl?
system. Who knows? Maybe Tandy has some future
terminal package software plans in mind. It sure would be
nice, however, to use this package under Disk Basic.
The ROM based operating software of the Modem Pa*
is much enhanced over that included in the Deluxe RS-235
Pak. The unit itself is a great step in the right direction.
However, I feel certain additional features would have
increased the value of this product. For instance, inclusion
of an RS-232 jack on the side would have allowed use with
external modems. Along with this, Tandy might have
included a provision for altering the communications Baud
rate when using an external modem. With prices dropping,
many people are going the extra bit and buying 1200 Baud
modems. It is a shame they won't be able to use them with
the Modem Pak. Also, I feel the inclusion of what Tandy
calls Xmodem is nothing more than a waste of good ROM
space. They might as well have left this "feature" out.
Despite any shortcomings, the Modem Pak is a well-built
piece of equipment. The documentation is more than
adequate and covers all phases of operation. In their usual
style, Tandy has included the schematic and programming
examples for controlling the modem in BASIC or assembly
language. I can recommend this unit for those who do a
moderate amount of telecommunicating. Its relatively low
price far outweighs its shortcomings for these people. Ill
give the Modem Pak a three-star rating on my four-star
scale.

Interactive Wishbringer —
A Stimulating Challenge
On a scale of one to 10, Pd give Wishbringer 9.95+ points.
Wishbringer is an interactive fantasy — you interact with
the program to create a story with many possible solutions.
Unlike many Adventure games, which accept only two-
word phrases (typically a verb and object), Wishbringer
encourages you to talk to it in complete — even compound
— sentences. Every aspect of this package has been carefully
designed and implemented.
To enjoy this fantasy, you need a CoCo 2 with 64K of
memory and a disk drive. Optional items include a second
disk drive and a printer.
The object of this fantasy is to free the seaside village of
Festeron of trolls, vultures and fortress-like towers. At the
fantasy's beginning, you are a postal clerk, with the task of
delivering a strange-looking letter to the local Magick
Shoppe. When you succeed in reaching the shop, you learn
that the proprietor's cat has been kidnapped by the Evil
One. She asks you to rescue her cat, and in return she will
give you a stone with magical powers — Wishbringer. Upon
leaving the Magick Shoppe, you discover that the once quiet
and peaceful village has become a battleground between the
forces of good and evil. Only you, with the magical
assistance of Wishbringer, can rid the town of its evil
inhabitants.

The documentation supplied with this program is superb.
The 25-page, color instruction manual contains the legend
of Wishbringer and complete operating instructions,
Suggestions are presented for the novice, and even a sample
script is included to illustrate how the fantasy develops.
Instructions are given to save a position in the fantasy and
to restore to that point. Additional instructions allow you
to send the actual script you create to the printer. Appen-
dices describe system commands, list some recognized
verbs, explain error messages (called Wishbringer Com-
plaints), and present copyright and warranty information.
Appendix G gives a brief biography of the fantasy's
originator, Brian Moriarty.
But the documentation doesn't stop with the superb
manual. Also included is a poster-sized postal map (also in
color) of Festeron, showing the roads and identifying many
of the buildings (but not the Magick Shoppe). A reference
card summarizes much of the information presented in the
manual. It also details a diagnostic procedure which will
check if the story data are correct (complete and undam-
aged). (This allows you to determine whether a problem is
hardware- or software-related.)
Still another piece of documentation is the sealed letter
you are to deliver to the Magick Shoppe. You open this only
when instructed by the fantasy to do so.
The packaging is excellent. In addition to the documen-
tation, Infocom has included a warranty registration card
(submitting this card gets you a complimentary subscription
to the New Zork Times newsletter) and several pieces of
advertising literature. One of these announces the availa-
bility of hints and maps for purchase.
Although I am past the age that is so fascinated with
games, I really enjoyed doing this review. I was constantly
challenged and frequently surprised as the fantasy evolved.
The documentation left nothing to my imagination (except,
of course, the fantasy itself). Response was quick, and often
revealed the author's sense of humor.

Software Review mSS^SSSSSSSSSSSSS^r^\
Keep in Touch with Mailing
List/Data Information
A number of mailing list programs, capable of storing
addresses and printing on self-sticking labels have been
available over the years. Mailing List /Data Information by
Crockett Software, offers several unique features that make
it attractive. It can store and sort a large number of
addresses, store additional data for each address, sort by
number or letter, and can rapidly search using key words
or numbers.
My review copy of this program arrived on cassette tape
which is easily converted for disk operation. I would
strongly recommend disk operation because of the ease of
computer/ disk interaction versus the difficulty of storing
and updating data on tape. The program requires a slight
change in a statement (AO$=DISK from TAPE) to convert
to disk. The programmer did an excellent job in making the
program so easily convertible.
Mailing List /Data Information contains two programs.
The first, PCEXT must be run first if you have Extended
BASIC to condition the computer. Then run GEMLIST
which is the operating program. The program runs on 16K
or 64K systems with or without Extended BASIC. The
number of files available is limited by RAM size. Two
hundred files are available for 64K.
The manual is well-written with good, easily followed
instructions. It contains a useful appendix of states and
commonly used abbreviations, a tapedisk routine for
converting tape data files to disk and a merge program for
combining two or more records.
On running the program, the user is given the option of
creating records or loading recorded data. Input is in the
form of a name, three address lines and three data lines.
The name is entered with last name first, but a print option
allows it to be printed first name first. Commas may not
be used. One may use all or a part of the address lines. The
data lines, which are not printed for labels, are useful for
telephone numbers, occupation names or other descriptive
information. This is particularly useful in the search routine
where you can call out by address or data item.
The program locates records by I.D. number, name or
any term used. It sorts files by file number, name or ZIP
code. It also allows editing of all input for changes of
address or any input data changes. Files may be reviewed
at varying rates of scrolling.

CoCo Community Center
THE RAINBOW S CoCo SIG

DELPHI
Storing files is easily accomplished using the Record
command. Retrieval is facilitated by an automatic DIR
which displays stored filenames.
Printing can be for all addresses and data or addresses
alone. When printing labels, the Address Only option is
used. The program prints two self-stick labels across a page,
or single labels. It also prints on one-inch or one-and-one-
half-inch labels. One minor irritation was a printed
statement following label printout of the number of labels
printed, which wasted a label and upset the spacing for more
labels. I eliminated that irritant by changing Line 66 in
GEMLIST
Need your plumber but can't remember his name? Locate
the file with "Plumber" in the data. It would also be useful
for Church or other organization mailing lists, small
businesses (or larger ones), anywhere you want to file and
maintain names, addresses, and pertinent data.
As far as program limitations are concerned, it will store
up to 200 records for a 64K system. However you can
maintain several 200 record files on a disk by simply using
a different filename for each one.
I would recommend this program for maintaining your
address and telephone files. It is the best that I have seen
because of its speed and multifeatured capability, particu-
larly the Locate and Sort capability.

A2D Deluxe Joystick:
What More Could You Ask?
The A2D Joystick is slightly larger than the standard
CoCo joysticks I'm used to. It's about the size and shape
of other deluxe joysticks on the market, which is to say just
about right. It appears to be well and sturdily constructed.
The firebutton has more "throw" than the run-of-the-mill
model, and has a very positive action.
Unobtrusively tucked away on the bottom of the case are
two small dial-type switches that control the modes of
operation. A flip of a switch allows self-centering operation
or free-floating operation. The two axes are controlled
independently, so the horizontal can be free-floating while
the vertical is self-centering (or visa-versa).
The mechanical trim adjustment for each axis is accom-
plished by way of two slide switch mechanisms located on
the top of the case. These slides are stiff enough to prevent
accidental adjustment. To test the operation of these trims,
I wrote a short BASIC program to display the integer (zero
to 63) returned by JOYSTK(O) thru JOYSTK(3), as
determined by the positions of the horizontal and vertical
axes of both joysticks. In the free-floating mode, centering
the trim control allows the full range of zero to 63.
Maximum trim adjustment shifts these values by approx-
imately 23 (zero to 40 or 23 to 63). In the self-centering
mode, the trim allows adjustment of the "position" returned
to by the centering mechanism. The centering mechanism
seems to be very precise. Once adjusted to a certain number
with the trim adjustment, the centering always returns to
that number.
Using the same program mentioned above, I tested the
A2D against the common garden variety RS joystick. With
the RS it was difficult to move smoothly one number at a
time. It was also difficult to stop on a chosen number —
I got the feeling that a sneeze two doors down might change
the display from 39 to 40. With the A2D, however, one step
at a time was a breeze. In free-floating mode I could stop
on 39 and set the joystick down on the desk without
affecting the display. This level of precision must be an
advantage for any application. Co Co Max came imme-
diately to mind. While I was not able to test it with CoCo
Max, I'm certain the additional control offered by the A2D
would be very helpful with a system which allows joystick
control of the entire 256 by 192 Hi-Res screen.
A2D: what more could you ask of a joystick?

Master Disk — A Simple
Program to Catalog Files
Master Disk assists in cataloging all your disk files. Il
requires 32K and is based on a program by Paul Selig in
the December 1983 issue of THE RAINBOW. Master Disk will
create, sort and save a disk library of filenames. It can hold
up to 18 directories or 250 program names in a single file.
Multiple files can be created so you can catalog all your disk
files.
After correcting four bugs, I found this program easy to
use, and it does its job well. The bugs were minor and
probably caused by the author trying to strip out spaces,
etc. I have reported these to the author and I'm sure they
will be cleaned up by the time you read this review.
Master Disk is menu driven and provides good on-screen
prompts. There are two menus. The main menu allows you
to create a new directory or recall an existing directory. The
activity menu allows you to add to file, find a selected
program, review entire file, or save to disk. Master Disk will
record the disk filename and extension and the disk name
(up to nine characters) for each file.
Reports can only be printed to the screen. When looking
at the screen reports, 10 files are displayed at a time.
There is no hard copy documentation with this program.
There are enough on-screen instructions to satisfy that need.
There is no information supplied with the program to
indicate what size CoCo is needed.
If you are looking for a simple program to catalog disk
files, then this may be the one. But you may be disappointed
if you're looking for something that is sophisticated and has
lots of features.
Master Disk is a freeware program, so the most you're
out is postage if you don't like it.

Amiga, Apple He, Atari ST-520, IBM PC,
Macintosh, Robotics and the VME bus
were the buzz words at the OS-9 community
buffet Sunday morning at RAINBOWfest
Chicago. What do all these computers have
to do with OS-9? They will all run it soon!
That's the word from James W Moore Jr.,
the Coordinator of Technical Services at
Microware. Bill told about 35 OS-9 aficio-
nados the 68 K world has not had an across-
the-board operating system and Micro-
ware's OSK is the ideal candidate. Why?
"OSK gives you the ability to move
software across many different machines,"
Moore said. "This will be great for software
developers."
After mentioning all the new OSK ports,
Moore turned the audience's attention to
CD-I, noting that the applications well use
everyday in our homes in 1988 haven't even
been dreamed up yet. "The possibilities are
staggering," he said.
And, how does this affect the Color
Computer OS-9 user? "They 11 be way ahead
in the game," Moore said. "CoCo OS-9 gives
them a gateway to the 68000 software used
heavily by industry today. Since the 6809
and 68000 bear such a strong family herit-
age, it is very easy to port most applications
from the 6809 to the 68000. Besides, the 6809
is the best and probably the last 8-bit
processor. It is still an important product,
but more importantly, it is a mature prod-
uct. It has a lot of life yet."
Moore predicted as all these new OS-9
ports and systems appear, the programmer
with CoCo OS-9 experience will have an
edge. Their knowledge is directly applicable.
"There is a window of opportunity opening
up," he said. "Go for it."
Bill Moore and User Group president
Brian Lantz both called 1986 the year that
OS-9, an underground classic for several
years, hits the light of day. "We have seen a
lot of interest from the press and the public
in the past several months," Moore said.
"Some are even naming OS-9 as a potential
competitor to MS-DOS in the 68000 world."
With the world waking up to the wonders
of OS-9, it's a shame that only 35 people
were able to join Users Group members for
the OS-9 Community Buffet. I hope to see
you at the OS-9 Buffet during RAINBOW-
fest Princeton.
Getting the Words on Disk
Many people on the CoCo SIG and at
RAINBOWfest Chicago have asked us to
recommend a good word processor for use
on OS-9. It's a personal choice and it
depends on the hardware you are using.
However, since problems seem to be pop-
ping up with many of the established word
processors when they are used with some 80-
column cards and Tandy's OS-9 Version
2.00.00, well offer a few thoughts.
If you are still using a standard issue
CoCo without a hardware 80-column card,
here's something you might want to think
about. Why not use the Desk Mate editor?

because it lets you perform physical input/
output operations directly to a disk. Nor-
mally, you would be reading or writing to
a directory or a file. When you append the
commercial "at" sign (@) to a device, you
are telling OS-9 that you want to treat the
entire disk mounted in the drive as one
logical file. And, since Logical Sector
Number 0 is the first logical sector on any
disk, patch looks at it as soon as it is called.
Now let's look at the two script files.
Script File Number 1
mOOOl
q
Script File Number 2
m 000 1
00
40
01
oo
/
i 0EB4 0IFF 00
q
The first script file simply positions
patch's edit pointer to the second byte in the
file. The 05 then replaces the 08 and the AO
replaces the 00. The slash (/) tells patch you
want to exit the edit mode. The 'q' lets you
exit from patch.
The second script file is used after the
RAM disk contains the information from
your floppy disk. First, it changes the second
and third bytes back to 08 00, or 2,048
sectors. Then, it changes the number of
sectors per track, 12 Hex, in the floppy, back
to 40 Hex or 64 in the RAM disk and
restores the number of bytes in the RAM
disk allocation map to 0100.
The two additional changes are needed
because when you backup the floppy to the
RAM disk, Logical Sector Number 0 from
the floppy disk is copied into Logical Sector
Number 0 of the RAM disk. If you didn't
change it back, OS-9 would think the RAM
disk was a 1,440 sector floppy disk.
The next to last line in the second script
file restores the last part of the RAM disk's
bit map to its original state. In patch y the *i'
means initialize. We are initializing, or
clearing, each byte between 01B4 and 01FF
to 00. Here's why.
The bit sector allocation map begins at
0100 on both the floppy disk and the RAM
disk. The bit map from the 1,440 sector
floppy disks ends at 01 B3. We need to tell
OS-9 that all the sectors beginning with
sector number 01B4 are free and may be
used by other files. We do this by clearing
them. The same procedures work with any
size floppy disk and any size RAM disk if
you change the two script files to match the
two disks you are working with.
OS-9 at RAINBOWfest Chicago
Congratulations to Steve Bjork of SRB
Software in Simi Valley, California, Steve,
who just last February received the "most
improved attitude award" from the OS-9
Users Group when he finally started writing
programs for OS-9, delivered the keynote
address at the CoCo Community Breakfast,
and much of his speech was about OS-9. He
gave a sneak preview of the new "Model 13"
from Tandy complete with slides of the two
"Mickey Mouse" processors it reportedly
contains. It looked like he shot them on
location at Disneyland where he once
worked.
Following his short audio-visual presen-
tation, Bjork highlighted the progress the
Color Computer has made, spotlighting the
new 80-column cards, the Tandy Sound/
Speech Cartridge and the Deluxe RS-232
Pak. Asked why he uses the RS-232 car-
tridge instead of the pseudo serial port on
the back of the CoCo, Bjork replied that he
doesn't do "bit banging."
He talked about selling computers to
people who have never used one. "Some
can't even use a hammer!" he said. "We need
to make it easier for them to run a computer.
I'm no different. When I want to write a
letter, I want to write a letter, not write a
program to write a letter."
After mentioning the new hardware,
Bjork revealed the secret of why Tandy has
moved all its software production over to
OS-9. "When you add all these devices, you
need an operating system. Without OS-9, all
you have is Microsoft basic. Besides, Mi-
crosoft doesn't know how to write an oper-
ating system. Just look at MS-DOS," he
said, generating a round of laughter from the
crowd.
"After much research, Tandy picked up a
then relatively obscure operating system
named OS-9," Bjork said. "Today they only
support three operating systems: MS-DOS,
OS-9 and Xenix. They needed an operating
system to carry their software in case they
changed their machine."
Bjork also praised the OS-9 programming
languages, noting that they are almost
completely bug free. Few operating systems
manufacturers can say that today. Non-
experienced users will find it much easier to
use the CoCo in the future. He said the OS-
9 based DeskMate was a step in the right
direction, giving beginners a lot of easy-to-
use functions at a reasonable price.
He sparked the imagination of the au-
dience when he talked about the new CD-
I standard recently introduced by Sony and
Phillips. CD-I, which features interactive
audio, video and computer data, is driven by
a special version of OS-9. To get people
thinking, he talked about a "bird book,"
telling the audience they would be able to
give their CD-I based portable computers
the location, time of year and a description
of the mystery bird they were looking at. The
computer could then return the name of the
bird. He thought it might be possible to feed
the sound of the bird into the computer and
match it with the pre-recorded sound of the
bird stored on the compact disk.
Bjork called CD-I an appliance computer
and said it would give birth to entertainment
disks beyond our wildest imagination. As a
technical aside, he mentioned that the VDG
chip in the CD-I players uses 100K of
memory for each picture (compared to 6K

experiments, you gain a practical tool and
a knowledge of another facet of OS-9 at the
same time.
This month, the desire to experiment was
driven by the fact that I do not own 80-track
double-sided drives but do own one of Tony
DiStefano's brand new 512K Super RAM
cards from CRC Inc. If I used the tricks I
published in June with the 512K RAM Disk
and double-sided 40-track drives, I would
lose nearly 200K of fast RAM disk, not a
viable alternative. I wanted to put every byte
of the 512K RAM Disk to work.
Finally, one afternoon while plodding
along the Mt. Vernon bicycle trail, I had a
brainstorm. "Why not format the RAM disk
to its full 512K capacity and then go in and
change Logical Sector Number 0 to make
the backup command think the RAM disk
was the same size as the floppy disk. I could
then do the backup quickly. After the
backup command had finished its job, I
could change Logical Sector Number 0 back
to its original state and make OS-9 believe
the RAM disk was full size. In real life, it
wasn't quite that simple, but it worked.
We'll look first at Logical Sector Number
0. At the highest level, OS-9 communicates
with many different types of hardware
through a hierarchy of file managers, device
drivers and device descriptors. An OS-9
module named IOMan, short for Input/
Output Manager, manages the flow of
information. To do this job, it relies on
several subroutine packages designed to
communicate with different types or classes
of hardware.
The most used of these subroutine pack-
ages are SCF, short for Sequential Charac-
ter Files, and RBF, for Random Block Files.
SCF contains a set of routines designed to
work with any hardware that sends or
receives data sequentially. For example, a
terminal sends one character at a time from
its keyboard. Likewise, the printer receives
one character at a time. SCF manages the
flow of these characters to the modem,
printer, terminal or any other serial device
you have attached to the Color Computer.
However, floppy disks, hard disks and
RAM disks behave differently — they send,
receive and store information one block at
a time. If you were to describe them academ-
ically, you would probably call them
random-access or block-oriented mass
storage devices.
The RBF module is intelligent enough to
maintain the logical structure of every file
stored on all random access devices. It sends
and receives 256 bytes at a time to your
hardware by using the proper device driver.
However, RBF never needs to deal with the
physical details of the read or write opera-
tion. The device driver keeps track of things
like the physical track and sector address of
all data on each disk. RBF only needs to
worry about the logical sector number.
The first logical sector on a disk is Logical
Sector Number 0. The number of the last
logical sector is one less than the total
number of sectors available on the disk. The
device driver, CCDisk in Color Computer
OS-9, translates each logical sector number
passed by RBF to the physical track and
sector address.
RBF is generic and knows how to com-
municate with many different storage de-
vices. But before it communicates, RBF
must know what type of device it is talking
to. To find out, it reads the information
stored in Logical Sector Number 0 of the
disk mounted in the device. During this
read, the driver picks up a lot of information
about the physical layout of the disk. Two
of the most important details are the number
of tracks on the disk and the number of
sectors in each track.
This first logical sector is also known as
the identification sector. The next logical
sector contains the first part of a bit map,
or allocation map, that may fill as many as
256 sectors on a large hard disk drive. This
bit map tells OS-9 which sectors have
already been used to store data and which
may be used by additional files. The bit map
in the 512K RAM disk we are going to
modify just fills Logical Sector Number 1.
Following the bit map, you will find the
root directory of the disk. When we modify
Logical Sector Number 0 of our RAM disk
to make it look like a floppy disk, we are
changing the first four bytes in the sector.
Later, after we have backed up the floppy
disk to the RAM disk, we need to change
the first six bytes back to their original state
and rewrite part of the bit map. But first let's
look at the information stored in Logical
Sector Number 0.
During our experiment, we are going to
change the value of the total number of
sectors on the RAM disk to equal the total
number of sectors on our floppy disk. If we
look at Logical Sector Number 0 imme-
diately after we format the RAM disk, we
find the first three bytes are 00 08 00 Hex
or 2,048 decimal sectors. That makes sense
since 2,048 * 256 equals 524,288 or 512K. On
the other hand, our double-sided, 40-track
floppy disk contains 1,440 decimal sectors.
If you translate 1,440 to Hex you get 05 AO.
So to pull our first trick we must change th<
00 08 00 to 00 05 AO. Since the first byte oj
each value is zero, we need only change tfy
second and third bytes of each three-bytt
value.
While we are examining Logical Sectoi
Number 0 of our RAM disk, we need to note
two other values. We need to know tnc
number of sectors per track and the numbei
of bytes in the allocation map. When w«
look at the chart, we see that this informa-
tion is stored at an offset of three and foui
bytes, respectively, from the beginning of the
sector. During our examination, well notice
that our 512K RAM Disk was formatted
with 40 Hex or 64 sectors per track. Well
also see that our RAM disk has 01 00 Hex
or 256 bytes in its allocation map. Jot this
information down; well need it later.
We used the patch utility from Computer-
ware's OS-9 Disk Fix and Utilities package
to make the changes. Further, we put our
input to patch in two script files and wrote
a short procedure file to do the entire job for
us. First, here is the procedure file.
load echo
echo Formatting Ram Disk Now
format /r(3f >/nil
yDisto Ram Disk
echo Patching Ram Disk Now

yy
echo Restoring Ram Disk Size Now*
patch /R0<3 <script2 >/Nil
echo Enjoy Your New Super Ram
echo from Tony Distefano and CRC
unlink echo
There are a couple of things you should
notice in the procedure file above. First, we
are patching something called "/ R0@." And
second, the device descriptor nil. The latter
allows you to throw away the output of a
program. It comes with Version 2.00.00 of
OS-9 from Tandy.

KISSable OS-9
Experimenting with
RAM Disks
By Dale L. Puckett
Rainbow Contributing Editor
Progress has been plodding along at a
snail's pace here at KISSable OS-9
headquarters. Our original $499, 4K,
1979 "Model D" CoCo finally bit the dust
and we were forced to lay out $69 to replace
it with a 16K CoCo 2. The 16K status didn't
last long, however; about an hour after we
picked it up, MOTD Editor Bruce Warner
and I had installed 64K memory chips. I
needed to get online fast because I was
falling behind in the testing of all the new
equipment/software now available to CoCo
OS-9 aficionados.
One of the most exciting opportunities
came from Fran McGee at Tandy who
loaned us a 15-megabyte hard disk to use for
a month or two. Next month, we hope to
present an action-packed chronology of our
adventures. This month, we follow up on the
RAM disk experiments we presented in the
June issue. We'll show you another trick that
lets you do backups from a floppy and still
use all the available space on the RAM disk.
Dale L. Puckett, who is author o/The
Official BASIC09 Tour Guide and co-
author, with Peter Dibble, of The
Official Rainbow Guide to OS-9, is a
free-lance writer and programmer. He
serves as director-at-large of the OS-9
Users Group and is a member of the
Computer Press Association. Dale
works as a U.S. Coast Guard chief
warrant officer and lives in Alexandria,
Virginia.
We'll be telling you about some of the
information stored in Logical Sector
Number 0 on all OS-9 disks. We'll also look
at a CoCo/ IBM data transfer utility pack-
age and feature a UNIX-like stat routine
written in assembler for OS-9, a BASIC09
pretty printing program and a C program
that adds a header to the standard line.c
utility.
First however, we must pass along an
addendum and a correction. Tom Roginski
of Owl- Ware, P.O. Box 116-D, Mertztown,
PA 19539, 800-245-6228, contacted us about
the Winchester basic we described in the
June issue. Al Reinhart, the program's
author, sent us the information earlier this
year. He called the program wbasic. The
proper name for the program is Winchester
basic and you can buy it from Owl- Ware.
The price is $50 when you buy an Owl- Ware
hard disk drive — $75 when you buy it alone.
We try to include the name and address of
the vendor when we describe a program, but
this one slipped through the cracks.
Turning to corrections, in May we gave
you a really slick shortcut to use when you
need to OS9Gen a new disk. Unfortunately,
my fingers weren't listening to my mind and
I typed the wrong command line. The
command line should have read, Is !
os9gen /Dl <ENTER>. To use this tip, create
a new directory. Then, copy or save the

After developing and testing the proce-
dures needed for this month's RAM disk
experiments, I was surprised to receive a
message from Dennis Skala on rainbow's
Delphi CoCo SIG. He had taken a similar
approach with his RAM disk.
"I read your June column with interest,
especially the handstands you were doing
while trying to get a floppy disk quickly
copied to a RAM disk without losing a large
chunk of the RAM disk's capacity. I went
through a similar process when I first started
using my RAM disk," Dennis said.
"I didn't think of formatting the floppies
in a non-standard way. Rather, I rewrote the
backup utility and removed the requirement
that the drives have the same number of
sectors. This means I can copy any type of
disk to the RAM disk — single- or double-
sided, 40- or 80-track. I wrote the new
backup command so that the balance of the
RAM disk in excess of the floppy's capacity
remains free," Skala said. "I also picked up
a bonus — I can now quickly backup a
standard Radio Shack 35-track disk to one
of my 40-track drives." YouH be happy to
know that Skala has uploaded his new
backup command to the OS-9 database
section of rainbow's CoCo SIG on Delphi
and it is available there for you to download.
One of the main reasons we publish these
little experiments is to provide a practical
project to share some of the details that
make a complex operating system like OS-
9 powerful. When you duplicate one of these

changes, subscripting and superscript-
ing. For example, you could call for
extended letters to type a title or head-
ing and return to normal type for the
body of text.
Print formatting commands change
format settings in PenPal itself like
margins, page lengths, line spacing,
centering of text, right justification,
page numbering options, form feed
(new page) and wait after each page is
printed. The only thing missing is page
headers. These formatting commands
permit changes to be made in the middle
of the text. For example, you could
change the left margin to indent a
quotation or a list. When the quotation
is entered, a formatting command is
included to reestablish the original
margin for the following text. If you
don't like the default settings for the
basic document, lead off with print
formatting commands at the beginning
of the document. Justification and page
numbering choices would certainly be
made there.
Write has a few limits. You cannot
print out a book manuscript by queuing
files as with Telewriter and DynaForm.
It does not do mail merge. It lacks
headers, footers and footnoting capa-
bility. But, most users will never miss
these.
A final consideration is the way
PenPal saves the text buffer. Like
DeskMate and a bunch of non-CoCo
programs, paragraphs are written into
the buffer without delineation of lines
within the paragraph. A carriage return
character ends the paragraph.
The file on disk is in ASCII format,
but apparently lacks the end-of-file
designation BASIC expects. To read a file
into a BASIC program, two things must
be done. First, carriage returns must be
inserted into long paragraphs to break
them into segments short enough to fit
into a BASIC string variable. This must
be done by editing the file in PenPal and
inserting carriage returns at the end of
every second or third line on the screen.
PenPal shows you where there are
carriage returns in the document. Next,
the file must be run through a BASIC
program to save the text to a new disk
file that handles the end-of-file properly.
The following is an example of a pro-
gram to do this.
The program simply opens an input
and an output file as defined by the user.
The directory for each drive used is
displayed as a convenience. Strings are
read in with LINEINPUTB1 , fl$ and
printed both to the screen, so one sees
some action, and to the second file. One

would expect EOF(l) in Line 20 to
detect the end of file and close both files,
Since a proper end of file is lacking, the
program ends with an IE Error which
causes basic to close the files anyway.
The output file will be a proper ASCII
file that will load into a BASIC program
or into Telewriter.
Though I am typing this in PenPah
Write, I will transport it to Telewriter
for printing because I want headers on
each page.
From this examination of the Write
module, you can get the flavor of the
rest of PenPal. The Calc, Database and
Telecom modules each combine much
more than minimum functionality
coupled with some unique features.
Each are easy to learn and use. Some
operations like the screen update in the
Write module and the recalculation in
Calc are unusually fast while none seem
especially slow. All are function key
driven with a function key strip dis-
played or, in Graphit, displayable.
My overall impression was good at
RAINBOWfest, and a full day with the
package has reinforced that. The only
problem that might be significant is in
the file saving operation on a JDOS-
formatted, 40-track disk. It seems to be
wasting disk granules. Fewer granules
are reported to be available than should
be for the number reported used. For
example, if I add up the granules used
by the files on a 40-track disk, I find 19
of 78 granules used, but only 45 free.
Fourteen granules have been lost some-
where. This problem appears to be
associated with a 40-track disk format-
ted with JDOS since disk space all adds
up on a 35-track disk formatted by Disk
BASIC.
Next month I will discuss the other
modules.
PenPal is available from Four Star
Software, Box 730, Streetsville P. Q,
Mississauga, Ontario, Canada, L5M
2C2. Price is $89.95 U.S. Canadian
price is $119.95. The program is also
available from some U.S. dealers so

name); F3, Free; F4, Kill; and F5, Dir, are
identical to Disk BASIC functions. The
real fun begins with F6, Step, which
changes the stepping rate of the disk
drives and F8, Trks, which allows selec-
tion of 35- or 40-track drives. You need
another DOS like ADOS, CDOS or
JDOS to format disks to 40-tracks.
I ran into problems when I tried to
set up a 40-track disk. I used JDOS to
format a disk with 40 tracks and backup
the PenPal program disk to it. I ended
up with a 35-track disk probably be-
cause the file allocation table copied is
for 35 tracks. Next I formatted another
disk for 40 tracks and used JDOS to
copy a number of files across. Part of
each file was lost. Next I formatted a 40-
track disk and placed it in Drive 1. I
booted PenPal and checked available
sectors on Drive I. Free reported 73
granules rather than 78. I was able to
load files into PenPal from the 35-track
data disk and save them onto the "40-
track" disk, but never recovered the five
lost granules. More on JDOS 40-track
format problems later.
Finally, from the Main Menu, F7
saves all current settings to a Config file.
This way, when you boot PenPal, Drive
1 can automatically be the default drive.
All current printer defaults are set as
well.
As I mentioned before, the files
pertaining to a particular application
are listed under its name on the main
menu. The extensions clue PenPal on
what belongs where. For example, all
files saved from Write and saved as
ASCII files from other applications
carry a WP extension. Move the cursor
over a blank entry under the application
to start a new file or over an existing file
name to start editing. If a new file is
chosen, you are asked for a filename.
Write is the word processor. One of
the first things I noticed was the 32,510
byte text buffer. This holds a lot of text.
Any article in this RAINBOW would fit.
This compares with about a 12K buffer
in DeskMate.
PenPal is much like DeskMate in
cursor movement and editing methods.
It supports block commands to delete,
copy and move text. It also supports
buried printer control commands with
the ability to tailor these commands to
your printer and save these codes to the
Config file using F7 from the main
menu. Nine commands are available,
each with a toggle on and a toggle off
form. While six come predefined for
RS-DMP printers, you can change
these for your printer. These are needed
to provide for underlining, font

ACCESSIBLE APPLICATIONS
Getting in Touch
with Pen Pal
By Richard A. White
Rainbow Contributing Editor
Many people I spoke with at the
Chicago RAINBOWfest are
very satisfied with DeskMate,
considering it is a beginner's level
program. But, the folks at Four Star
Software aren't satisfied since they are
selling PenPal to do the same things.
James Norrie of Four Star gave me a
demonstration and ended up selling a
copy to me. The last thing I need is
another program to do word process-
ing, spreadsheets, databases, graphing
and telecommunications. However,
PenPal looked so good, I felt I had to
give it a real workout and let you know
what I found. PenPal requires a 64K
CoCo with one disk drive. Two drives
are better.
There needs to be two sets of stand-
ards when judging software of this type.
One is- the power and usefulness of the
individual modules and the other is the
value of the total package to the average
user who doesn't want or need most of
the bells and whistles in the more
powerful, single-application packages.
Let's look at each application in Pen-
Richard White lives in Fairfield, Ohio,
and has a long background with micro-
computers and specializes in BASIC
programming. With Don Dollberg, he
is the co-author of the TIMS database
management program.
Pal, then make a judgment on the whole
and look at the pieces more critically.
All applications use a common 51-
character by 24-line screen in the high
resolution graphics mode. Screen up-
date is the fastest I have seen on the
CoCo. One problem I have with Tele-
writer is that characters are lost when
the wordwrap scrolls the screen and
starts a new line. This has not happened
on PenPal. The whole screen seems to
move up one line as a unit and the word
being wordwrapped goes to the left
margin.
The top line of the screen displays a
command line in reverse video. This is
where things like the module name and
current filename are displayed. The
bottom two lines display a function key
strip, again in reverse video. Up to 10
functions are displayed which are called
by pressing the CLEAR key and a
number together. Some applications
have more than 10 functions in which
case the F0 (CLEAR-'O') toggles the
display of the alternate function key
strip. Only those functions currently
displayed by the function key strip can
be called, but the alternate strip is easily
toggled into view.
The five alternate functions are called
by pressing shift, clear and the
number key together. AFl invokes a
simple calculator that uses the com-
mand line at the top of the screen and
does not interfere with the display for
the application you are in. AF2 allows
the user to change the printer defaults
such as margins, page lengths, Baud
rate and the like. The defaults are
displayed one at a time in the command
line at the top of the screen and pressing
ENTER leaves the setting unchanged and
moves to the next. This is much faster
than loading graphics configuration
screens and saving them as DeskMate
does. You have the option of saving the
new defaults from the main menu. In
addition, the defaults are maintained as
you move from application to applica-
tion during a session.
AF3 toggles the screen background
color between green and buff. AF4 calls
the help file appropriate for the appli-
cation and AF5 produces a directory of
the default drive. AF12 exits an applica-
tion without saving the file. What is key
12? It's the minus sign. CLEAR and the
minus key (F12) will exit any function,
application, or the program from the
main menu.
When you LOfiDM PenPal and type
EXEC, you see the main menu. It pre-
sents a five-part table headed by the
application name with the names of the
files listed below. The function key strip
displays disk file functions. Fl, Swap,
changes the default drive. F2, Name(Re-

192 THE RAINBOW August 1986
The effective address is therefore S3E0C,
:he location of ARG1.
The other program counter relative in-
structions compute the address in the same
fashion. Since PCR-type instructions don't
contain an absolute address, they can be
placed anywhere in memory and execute
properly, even if they refer to locations
inside the relocated program. The expense
of using the PCR instructions is memory
(PCR instructions are longer), more com-
plexity and giving up a few other addressing
modes (you can't use auto-increment ad-
dressing together with PCR, for example).
A Character Generator for Graphics Mode
To tie all of these concepts together, we've
written a Character Generator program,
shown in Listing 2. The program allows you
to write any normal text character on the
screen in graphics mode in upper- and
lowercase. It also allows you to change the
size of the characters. The program assumes
you are in PMODE 4 (256 by 192, two-color
mode), you are using graphics page one and
you have a disk system.
The input parameters to the system take
the form of a BASIC string. The first char-
acter of this string is the 'X' position repre-
senting the upper left-hand corner of the first
character. The second character of the string
is the corresponding 'Y' position. The third
character is the size of the characters to be
written on the screen, from one to 16. The
remainder of the string is the text to be
written. As an example, suppose that you
wanted to write "This is a test" in the center
of the screen. The height of text for a text
screen is 12 pixels high and the width is eight
pixels. However, character positions for this
program are eight pixels high by eight pixels
wide to allow packing 24 lines on the screen.
The center of the screen is at X=128, Y=96.
The input string looks like this:
ZZ$-CHR$(128)+CHR$(96)+CHR$(1)+"THIS IS k TEST"
The screen output looks like Figure 4.

Figure 4:
Sample Character Generator Output
The ZZ$ string variable string was used
only as an example. Any string variable can
be used, as long as it has the *X' and 'Y'
positions and magnification factor in the
first three bytes. The sequence for calling the
Character Generator uses the VfiRPTR func-
tion:
1000 ZZ$=. . .
1010 B=VARPTR(ZZ$)
1020 A=USR(B)
Of course, the program must have been
relocated to protected memory and a DE
FUSR done to define the start — all of the
steps we described earlier. The program is
relocatable, by the way, so that it can be used
anywhere in memory you want to put it.
Program counter relative addressing is used
throughout the code.
Listing 3 shows a typical use of the
Character Generator in writing sample text.
The program must be on the disk in binary
form (the output of an assembler). The
program is relocatable and may be moved
anywhere in RAM, but allow 318 bytes for
the program. Change DEFUSR0 accordingly.
The resulting display for this test driver is
shown in Figure 5.

Figure 5: Test Driver Display
To change the size of the text, use another
value in the third byte. This byte represents
the magnification factor. To display charac-
ters 24 pixels high you'd have:
ZZ$-CHR$(12A)+CHR$(9?)+CHR$(3)+ B This is larger text"
The program uses a 1,024-byte character
pattern area called CHTAB, or Character
Table. The address of this table must be
POKEd into locations $13C and $13D as
shown in Listing 3. The Character Table can
be directly after the Character Generator
program, or may be anywhere else in mem-
ory. The first eight bytes in this table
represent the pattern for an ASCII character
of zero, the next eight bytes the pattern for
an ASCII character of one, the 65th set of
eight bytes represent the pattern for 'A', and
so forth. You can fill in your own characters
for ASCII codes not normally used in the
Color Computer, such as codes zero through
31. Each set of eight bytes represents the
eight rows that make up a character, as
shown in Figure 6.
The basic test program shows the pat-
terns for the uppercase alphabetic characters
A through Z and for a space character. Fill
in the remaining characters as the need
arises. All 128 positions in the table can be
used, and any symbols meaningful to you
can be used. Don't forget that the "scale
factor" allows an expansion of each pattern,

Suppose we had a program that refer-
enced a parameter block at the beginning of
the program area, something like this:
Is this really better than just assigning a
block of protected memory for the parame-
ter block? Probably not, but it is an alter-
native method,
VfiRPTR is handy, though, when working
with strings. If VfiRPTR is used to find the
location of a string, it returns not the address
of the string, but the address of a five-byte
string parameter block as shown in Figure
3. The third and fourth bytes of this parame-
ter block (+2 and +3) point to the location
of the string itself. If this string address is
used in the assembly language subroutine, it
must again be converted to an integer value
in D by a JSR $B3ED as shown here:
3E00 00

You can see that the LDA and LDB
assembled as "extended" addressing types of
instructions. Each instruction consists of a
one-byte operation code ($B6 and $F6)
followed by a two-byte address ($3E0O and
$3E01). What would happen if this code
were incorporated into DfiTfi statements and
then moved to the $4000 area? The result
would look like this:

Although the locations in which the
instructions were stored changed, the refer-

viously, when this program was executed, A
was loaded with the contents of location
$3E00 and B with the contents of location
$3E01 instead of the new locations at the
beginning of the program, $4000 and $4001.
This problem occurs for all references to
data locations inside the program, but not
to external fixed areas. If there were a
parameter block at memory area $5000, for
example, an LDA $5000 would be valid

Relocatability
In our examples and in last month's
column, we assumed for the most part the
machine language code generated and
stored in DATA statements started at a fixed
location — &H3E00 in our examples. A
typical assembly language program can't be
stored and executed just anywhere in mem-
ory. Let's see why.
wherever the program was moved. The same
thing applies to system memory areas like
the text or graphics screens — they are at
fixed locations.
The problem also applies to JMP and
JSR instructions, which jump to locations
specified by absolute addresses within the
instruction, generated at assembly time.
Branches, however, use relative addressing
in which the effective address for the branc
is computed by adding the contents of tr,
program counter to a displacement vali
within the instruction. Look at this pre
gram:

This program doesn't do anything; it's a
infinite loop. It does illustrate jumping an
branching, however. The JMP NEXT ir
struction assembles with a jump locatio
(after the IE op code) of 3E05. The BRy
FIRST, though, does not use an absolut
address. Instead, it uses a displacemen
value of F9. When this displacement valu
is added to the contents of the progran
counter, the result is the branch address. Th
program counter always points to the nex
instruction after the current one beinj
executed, in this case, at $3E07. Addinj
S3E07 and $F9:
S3E07
+ $FFF9
$3E00
The displacement value is "sign extended'
to the left, which must be done for negative
displacements of $FF through $80 (indicat-
ing branches backwards). Positive displace-
ments of $00 through $7F (indicating
branches forward) may be added without
sign extension. In any event, the result is the
jump address of $3E00. The BRA FIRST
could have been replaced with a JMP
FIRST instruction, but this instruction
would have used three bytes instead of two
bytes and not have been relocatable.
There's a way to make all instructions
relocatable. It's a special addressing mode
called "program counter relative." An
example is shown here:
3E00 00100
3E00 A6 8D 0008 00110
3E04 E6 8D 0005 00120
3E08 6E 8D 0002 00130
3E0C 00 00140
3E0D 00 00150

The machine language assembled for the

of 8D. The addressing mode byte is used by
the 6809 to determine how the address
should be computed. In this case, the effec-
tive address is computed by adding the
contents of the program counter to the
displacement value of 0008, found in the
, third and fourth bytes of the machine
language. The program counter points to
$3E04 at this point so:

ISR call.
Here's a simple example of the whole
irocess. The assembly language subroutine
dds one to an input argument and returns
he incremented value. It's a useless subrou-
ine, but itlJ give you a better idea of how
he process works.

JSR $B4F4 'reconvert

As you can see from the assembly lan-
guage program, the only processing actually
done in the program is to add one to the
contents of the D register. The first JSR
converts the input argument (found in
variable V in the basic program) to a value
in D. The second JSR reconverts the con-
tents of D (now V plus one) to variable V
for output. The RTS, of course, just returns
to BASIC.
Packing Arguments
Although only one integer value is al-
lowed, there's no reason several arguments
can't be packed into that single value.
Suppose you have an assembly language
subroutine to move a character around the
screen. The inputs to the subroutine would
be the character and the speed of movement.
These two arguments could be packed into
the single 16-bit integer value of the USR call
by doing this:
100 ' HOVE CHARACTER SUBROUTINE
110 CLEAR 1000.&H3DFF
120 CLS
130 FOR I-&H3E00 to &H3EXX

200 GOTO 170
'protect memory
'move mach lang
'define loc'n of al
1 input character
' input speed
'pack two arguments
1 recrun here
The character is converted to an eight-bit
ASCII code by the ASC(C$). It is then
packed into the most significant byte of the
input argument by the ASC(C$)*256. The
speed is also an eight-bit value and is in the
least significant byte of the input argument.
In the assembly language subroutine, the
two arguments appear in the D register as
shown in Figure 1, after they have been
converted by a JSR SB3ED.
This same scheme of packing multiple
arguments can be used for input and output
to pack as many as 16 single-bit arguments
into the input or output parameter. On the
input side, the arguments are packed by
multiplying the value by a power of two so
that it's shifted left and adding in other
arguments. On the output side, the argu-
ments are unpacked by ADDing and then
dividing by the same power of two. Some
examples are given in Figure 2.

150 ARG4=A-ARG1*4096-ARG2*256-ARG3*16
Figure 2: Packing Four Arguments
Parameter Block
Another way of passing multiple argu-
ments to and from an assembly language
subroutine is by a parameter block. The
parameter block is a special area in memory
set aside to hold input and output argu-
ments. A simple example of this is shown in
Listing 1, which is the partial assembly
language listing of the move character
subroutine. The first two bytes of the
subroutine are reserved for the character
and speed input parameters. The actual
subroutine starts at &H3E02 rather than
&H3E00.
The basic code for calling this subroutine
is:
100 'MOVE CHARACTER SUBROUTINE
110 CLEAR 1000.&H3DFF
120 CLS
130 FOR I-6.H3E00 to &H3EXX
140 READ A: POKE I,A
150 NEXT I
160 DEFU5R0-&H3E00
170 INPUT "CHARACTER-" ;C$
175 INPUT "SPEED (0-255)-" ;8
176 CLS
1B0 POKE &H3E00, ASC(C$)
190 POKE &H3E01, S
200 A - USR0(0)
200 GOTO 170
'protect memory
'move mach lang
'define start of al
'input character
' Input speed
'poke character value
'poke speed value
'go to al subroutine
'return here
The USR call uses dummy arguments
rather than packing the two input parame-
ters into a single argument. The two input
parameters are stored in &H3E00 and
&H3E01 by two POKEs. As long as the input
parameters are byte values (zero to 255), the
POKEs work fine. The assembly language
subroutine does not make a call to $B3ED,
as there is no argument to convert. It simply
picks up the first argument from &H3E00
(character) and puts it into A and the second
argument from &H3E01 (speed) and puts it
into B.
This concept can be used to pass any
number of arguments. Just allocate a large
enough chunk of memory to accommodate
all of the input and output arguments and
then do PDKEs before the subroutine is called
and PEEKs after the subroutine is called to
access the arguments.
It's important to note that the parameter
block holding input and output arguments
must be in a protected portion of memory.
Any address greater than the CLEPR address
can be used, and the parameter block can be
before or after the actual subroutine. Don't
forget to specify the actual starting address
of the subroutine, rather than the start of the
parameter block, if the parameter block is
located before the subroutine.
Using VARPTR
The VARPTR function in BASIC is also
handy for passing parameters to assembly
language subroutines. The VPRPTR function
returns an address to a specified variable.
Suppose that you had a variable called AA.
This code:
100 AA-3
110 B-VARPTR(AA)
120 PRINT PEEK(B) , PEEK(B+1) , PEEK(B+2) , PEEK(B+3) ,
PEEK(B+4)
prints 130, 64, 0, 0, 0. Where's the 3? That's
a long story.
You'd expect to see a zero byte followed
by a three byte, representing a binary integer
number of three. However, Color Computer
BASIC variables are always a "floating-point"
format, even when you are working with
integer limits, such as PEEKs and PDKEs. The
130, 64, 0, 0, 0 represents a power of two
equal to 130 minus 128 and a fraction of
0.11000000. The result is the power of two
(2 squared or 4) multiplied by + X A) = 4
* (%) = 3. This is not the easiest way to
represent numbers, and it would be very
tedious to have to convert to this floating-
point format every time you wanted to pass
parameters to assembly language. The
floating-point representation is why the JSR
$B3ED and JSR $B4F4 are used to convert
and reconvert variables passed to and from
assembly language subroutines.
There's nothing that says that a dummy
variable cannot be used to store parameters,
however. This code stores 100, 45, 233, 15
and 37 in the location of dummy variable
A A. The location of the dummy variable A A
is then passed to the assembly language
subroutine. However, the assembly lan-
guage subroutine must still go through the
"convert" subroutine to get a 16-bit address
value in D to point to dummy variable AA.

More Interfacing Tricks
for Assembly Language
and BASIC
By William Barden, Jr.
Rainbow Contributing Editor
Last month we described the elemen-
tary steps in tying together short
assembly language subroutines with a
basic program. Although assembly lan-
guage is a more difficult language in which
to write computer programs, it offers one big
advantage over basic and other "high level"
languages — speed. There are many things
that can be done in assembly language that
just cannot be done in other languages. In
the last column we suggested you start using
assembly language by interfacing, or joining
together, short assembly language subrou-
tines to improve your basic program's
efficiency.
We discussed the difference between
assembly language and machine language —
machine language is made up of the binary
data the 6809 recognizes as part of its
instruction set while assembly language is a
more English-like representation of instruc-
tion mnemonics. The assembly language
form is translated into machine language by
a program called the assembler, typically the
Radio Shack EDTASM+ assembler.
We also described some assembly lan-
guage programs and mechanisms to inter-
face them to BASIC. The BASIC statement that
Bill Barden has written 27 books and over
100 magazine articles on various computer
topics. His 20 years experience in the indus-
try covers a wide background; program-
ming, systems analyzing and managing
projects ranging from mainframes to micro-
computers.
defines where in memory the assembly
language code resides is DEFUSR, as in 110
DEFUSR = &H3E00. The BASIC statement to
actually make the jump is USRn, as in 1B0
R = U5R0(0). Each assembly language
subroutine must have an ending RTS in-
struction, which acts like a BASIC RETURN
statement, returning to the point just after
the USR call.
Before an assembly language subroutine
can be used, however, the memory area in
which it is to reside must be protected by a
BASIC CLEAR statement, as in 110 CLEAR
1000,&H3DFF. This prevents BASIC from
overwriting the machine language bytes as
it stores data such as strings and its own
internal variables. The machine language
code making up the assembly language
subroutine is moved into this protected area
by loading a machine language program
from disk or cassette, or by reading DRTR
statements in BASIC and doing a series of
PDKEs. We chose the POKE route for our
examples.
The USRn statement in BASIC has an
argument in it that represents an integer
value. A single integer value can be passed
to the assembly language subroutine by this
argument in a statement such as 1B0 R =
USR0(1000), which passes the value of
1,000. The assembly language subroutine
may pass an argument back by the USR. The
argument is returned in the variable on the
left side of the USR statement; in this exam-
ple, Variable A contains the result. However,
it's perfectly all right to pass no arguments
and to use dummy variables in the USR
statement.
Well continue with more tricks in inter-
facing assembly language with basic in this
column.
Passing Multiple Arguments
to AL Subroutines
The argument passed to an assembly
language subroutine must be an integer
argument — a numeric expression, variable,
or combination that can be resolved down
to the value of -32768 through +32767. Here
are some typical USR calls:
100 A = USR0(1000)
200 VX - USRl(AC)
300 AN = USR4(1000 - ZT)
Passing One Argument
In the assembly language subroutine itself
(as we saw last month), the code must do a
JSR $B3ED to convert the input argument
to a 16-bit value in the D register (the A and
B accumulators). After this is done, the
assembly language subroutine can use the
input argument as required — to define a
delay, to point to a work area, to define a
character, or any other application.
To pass an argument back to basic, a JSR
$B4F4 is done in the assembly language
code. This converts an output argument in

Device Overload
• / have a 64K Color Computer 1 with a
J&M disk drive system and a DCM-5 Auto I
Answer modem. How does one operate a
disk controller, a DS-69A Digitizer, a
CoCoMax joystick port and an RS-232C
Deluxe Pak all at once? It is all on one
switch, and obviously it would be very
difficult to switch to each slot. This leaves
the option of switching using software.
Jeff Wozniak
Apply Valley, MN
Even though you can both hardware-,
and software-select a Multi-Pak slot, the
address and data lines are connected to the
device at all times, Jeff. This means by
adding address decoding circuitry to the
accessories you mention, they can all be
resident at the same time. Remember, the
CoCo can switch between these devices
about 250,000 times a second.
Nonexistent Clock Signal
• I recently purchased a VIC 1525 graphics
printer by Commodore. It resembles the
DMP-100 printer by Radio Shack.
I would like to use the 1525 with my
Co Co. Can it be done? What wiring config-
uration do I make to connect serial 1 1 0
ports?
Philip Tack
Worthington, PA
Philip, according to the diagram you sent
us, the VIC 1525 requires a clock signal from
the computer. This signal is not present on
the CoCo serial port.
Disk Drive Debate
• / am debating buying a hard disk or a
floppy disk drive. How compatible is an
Amdek hard disk with the software on the
market, and how much extra storage does
it have?
Byron Fast
Kleefeld, Manitoba
Byron, I am not aware of an Amdek hard
disk. I do know that Amdek makes a V/2
inch floppy disk. It is the same as a 514 inch
floppy disk, except it is packaged a little
differently. It has the same storage capacity.
I would recommend you have at least one
5i4 inch disk drive in your system.
New VDG for Older CoCos
• The CoCo has an MC6847 Video Display
Generator (VDG) that is less than perfect.
Motorola has designed a new VDG, the
MC6847T1, which will soon be released for
full production. What does it do? It makes
clearer symbols, changes the *o from square
to circular, adds a slash to the zero and gives
lowercase with descenders. The MC6847T1
has a data latch 74LS273 and a buffer
74LS244 on board.
How can you use it? Find the VDG
(MC6847T1) when released. Remove the
74LS273 from the circuit board and jumper
the socket so the lines go straight through.
Use two sockets (40 pin) to make a jumper
socket for the VDG. Jumper the data lines
3 through 8. Connect pin 10 to pin 25 with
a 2.5 K ohm resistor. This allows pseudo
colors. Connect pins 12, 17 and 24. This
disables the I I O lines not used by the Co Cos.
This is the area that replaces the 74LS244
(buffer). It would require extensive wiring to
use it. Connect pin 13 of the VDG to pin 11
of the 74LS273 socket. This is the RAS
signal and it stabilizes the output. Connect
an SPDT switch by connecting one side to
pin 1 of the VDG, center to pin 31 of the
VDG, and the other side to pin 31 of the
VDG socket. Make sure pins 12, 13, 25, 26
and 31 are not connected through to the
circuit board side.
What happened to the lowercase? This is
caused by a ROM text screen 0 reset; to
disable it use POKE 359,57. The only
problem with this poke is that if you are
running a graphics program and have an
error in it, the text screen does not come
back with the error message. You must enter
text screen. Next enter POKE 65314, X.

Memory Exploration
• I'm writing a machine language program
to allow exploring CoCo memory. I want it
to work in 64 K RAM mode without the
ROM support. I have to build every routine
and most of them are finished except two:

the PIA for the shift key.
RS-232 — I don 7 understand how to send
information to the printer and how the
timing process works.
Marc Gagnon
Cap-de-la- Madeleine, Quebec
Marc, you need to obtain a disassembly
of basic to fully understand the INKEV$ and
RS-232 routines. Color BASIC Unravelled
will do nicely.
If you want to try on your own, the
INKEYS routine starts at $A564. The test for
the shift key routine is at $ A22E. The RS-
232 output routine starts at $A2BF. All of
the above addresses are for Color basic 1.2.
Good luck.

When the Tandon Drive 1 is connected,

Ben Takemura

Ben, it appears that the drive select lines
on your Drive 1 are being enabled for both
Drive 0 and Drive 1. A normal disk drive
uses two pins for drive select and has binary
decoding circuitry to distinguish which drive
it's supposed to be. CoCo disk systems use
a separate drive select pin for each of four
possible drives.

some information, please.
I own an F board and am running 64 K,

the time, retain graphics. Is there anything
I can do about the 2N6594 transistor which
creates a heat problem? I replaced it with
heavy-duty NTE219 and heat sunk it, but I
still need to run a fan on it.
Kenneth Harman
Bakersfield, CA
You are correct Kenneth. In the No-
vember 1984 rainbow, Tony Sharp wrote
an article on how to convert a Modem I to
auto-answer. It was titled "Adding an Auto
Answer."
The only thing a heat sink does is allow
the heat to dissipate. Unless the heat sink is
external to the computer, the heat stays
inside until air from the ventilation holes
cool it. It*s best not to block the ventilation
holes by enclosing your computer. If you do,
it's necessary to add a fan to get rid of the
heat.

August 1 986 THE RAINBOW 1 83
cursor drawing, fast and clipped.
The cursor is put down byte by byte
rather than dot by dot to speed up the
drawing. If only one image of the cursor
was used, there would be only 32 posi-
tions across the screen. But the shape
data has four-image offset (0,1,2,3) to
give 128 positions. Of course, there are
192 positions up and down.
TURNOF (Line 28300) is the turn off
cursor function (zero). This subroutine
resets the cursor-enable bit and turns off
the cursor.
CUROFF is used to remove the
cursor if it is on the screen. The cursor
is removed by getting the old screen
data from CURBUF and putting it on
the screen. As with the cursor draw
there are two types of removes, fast and
clipped.
DSABLE is the subroutine for func-
tion number six, disable (or unlink) The
Mouse. After turning off the cursor, the
old interrupt, output and command
vector are restored.
S EL JOY is for functions nine to 13,
select joystick type.
Basic's 60-hertz interrupt vector is
passed through IRQ to move the cursor,
poll the joystick and button status, First
the status cursor and HOLD flag are
tested along with the joystick position
to see if it has moved. If the cursor
should be removed, then CUROFF is
called. Next, if the cursor should be
turned on (because of a new position or
hold is no longer on), then CURON is
called.
Lines 37800 to 38100 call Basic's old
interrupt subroutine. The disk drive
M0T0R0FF and TIMER function will still
work. Before end, the interrupt subrou-
tine, the joystick and button status are
polled.
At the end of Listing 1 are three
+GET instructions that include the
other files needed to assemble the
program. This +GET of my assembler
is very similar to the USE directive of
the OS-9 assembler.
The FCC in lines 40900 to 41300 adc
the copyright text to the end of The
Mouse program. ENDPRG is the
length of the program.
Mouse 2 (Listing 3) is the joystick
drivers used by The Mouse. The table
of offsets called JOYTAB, is used by
JOYSTK to call the right subroutine.
Each polling subroutine updates the
button up/down status flag (BUT
DWN) and returns the Y-position (zero
to 191) in the A register and the X-
position (zero to 127) in the B register.
Next month we will look at The
Mouse source code for the Hi-Res
screen text driver in files four, five and
six. *

next month's listings are intended for

rick to use the full range of the 5-bit
)ffset (-16 to 15) is to set the U register
16 bytes in the variable list. The value
)f the first variable is now -16 (pre-
viously zero), still in the 5-bit range. But
low 16 more bytes (and a few more
/ariables) can use the faster 5-bit offset.
Let's see how the first file (Mouse 1
— Listing 1) breaks down. The first 13
ines are the standard comments and
copyrights. SSTART and SEND are
constants for Basic's screen pointer
variables in direct page. SSTART holds
the starting address of Hi-Res screen
memory and SEND holds the ending
address plus one.
The first instruction is a long branch
over the program variable tables, data
buffers and command offset vectors to
the USR handling code. The next 386
bytes is the shape data for the Hi-Res
cursor. By loading data qver this space,
a new cursor shape can be displayed.
COMTAB is a table vector offset for
the 13 user functions. Each 16-bit entry
in the table is an offset (how far way)
from the start of the table to the address
of the function.
Next is the variable list used by the
program. The Data label is set up 16
bytes into the list for maximum use of
the 5-bit offset.
CURBUF is the buffer for saving
what's on the screen before the cursor
is placed. The cursor is removed by
copying the old screen data from this
buffer to the screen's memory. COM-
BUF is used as Basic's command vector
to intercept the *@' function in the
PRINT command.
So much for the variables and
buffers, now for code. First is the USR
function and commands. The routine
first checks to see if The Mouse is linked
into Basic's system. If needed, it hooks
into the 60-hertz interrupt, output port
and the PRINT command.
Down at the label USR1 (Line 13900)
the program tests for a string variable
and aborts if it is. After getting the
function number, the program jumps to
a subroutine based on it. When the
program returns, the number is passed
to BASIC and ends the USR function. The
subroutines for USR functions two to
four are in lines 15800 to 17100.
TURNON (Listing 2) is used to per-
form function 1, turn on the Hi-Res
cursor. This subroutine sets the cursor-
enable bit of the cursor-status flag byte
and draws the cursor on the screen.
CURON is the code that does the
drawing. After checking if it's OK to
draw, it finds the screen's memory
location for the cursor and determines
if it should use the clip draw. A clip
drawer only draws the part of the cursor
that is on the screen. A clipper could be
used even when it is not needed, but it
is very slow, about seven times slower
than the cursor draw without clipping.
Because of this there are two types of

MOUSE UTILITY
What's Inside a Mouse?
r ■ i refresh your memory, The
I f\Mouse is an assembly lan-
JL \^guage program that displays
and moves a cursor and prints upper-
and lowercase text on the Hi-Res graph-
ics screen. A BASIC program may access
this interface by 13 user functions and
the PRINT command.
This month We are going to dive into
the assembly language source code and
see just how The Mouse does its magic.
Because The Mouse is about 35K bytes
long, it is broken down into six files. We
will talk about three of them this month.
We will see the assembly language side
of the USR function and PRINT com-
mand along with the code for drawing
the cursor (pointer). Also, we will look
at how the joystick and button informa-
tion is polled.
Steve Bjork has been a programmer for
over 15 years. In his association with

lar Life Line, Ghana Bwana and PitFall

Before getting started I should re-
mind you that The Mouse and its source
code are copyrighted (1986) by SRB
Software with all rights reserved. It is
presented in RAINBOW magazine for
private use only and cannot be used (all
or part) in any marketed product with-
out written consent from SRB Soft-
ware.
A Few Points about Relative Code
The Mouse is a code-relative pro-
gram just like OS-9. The only difference
is there is fio direct page for the program
(the direct page is already used by
BASIC'S system variables). The standard
for address relative variables is LDA
YJOY,PCR.
This instruction (when using a 16-bit
offset) is about four bytes and nine
clock cycles long, a little on the big and
slow side. If The Mouse was a small
program with just a few variables, this
would not be much of a problem. But
the program is about 3K in size and
contains 26 variables, which could
waste about 200 or so bytes and make
it run a little slower.
If a 16-bit register was set up to point
to where the variables are at run time,
then a smaller and faster instruction
could be used. In The Mouse the I
register (User stack pointer, but no
used by BASIC as such) is pointed to th
variable block. The previous example
could be changed to LDA YJOY,U.
True, it does not look that different
but it is only about 2 bytes and 5 clocl
cycles long (about half the time anc
size). In The Mouse two types of offset!
are used, 5-bit and 8-bit. The 5-bit offsei
has an advantage over the 8-bit by bein|
one byte shorter and one clock cycle
faster. But there is one problem with the
5-bit offset, its limited range of -16 tc
+ 15 from where the pointer is address-
ing. Any offset out of this range must
use an 8-bit offset, which is longer and
slower. For this reason the most used
variables are placed at the start of the
variable table.
If the U register was just a pointer
to the start of the variables list,
only the first 16 bytes (offset
0 to 15) would use the
5-bit offset and all other
variables would use
the longer 8-bit
offset. One

Unless Brother has changed its design,
hat 12-pin connector is not a standard serial
>ort. You must send the signal from it to an
idditional optional $150 device sold by
brother, called the Brother IF 50 Interface.
The IF 50 Interface plugs into the typewriter
it one end with the required 1 2-pin plug, and
it the other end provides a buffered (2K size)
;erial and parallel port (you select one by a
switch on the IF 50).
On the DB-25 plug, which you will plug
nto the IF 50 Interface, you must short pins
I, 6 and 8. Then, hook up that plug via a
;hree-wire cable to the standard CoCo four-
pin DIN connector in the following manner:
Pin 3 of the CoCo DIN goes to Pin 7 of the
DB-25 which will plug into the IF 50, Pin
\ of the CoCo DIN goes to Pin 3 of the DB-
25 plug, and Pin 2 of the CoCo DIN goes
to Pin 20 of the DB-25 connector. You will
also have to properly set the Baud rate and
word length, etc., on the IF 50 and the
CoCo.
• / noticed a peculiarity when writing a
space game in BASIC'S PMODE 4. The blue
ship I drew might be red the next time I turn
on the computer or press the Reset button.
Why is this? Is there any way to predict what
color it will be?
Jason France
Yuba City, CA
You have discovered the "artifact color
flip" peculiarity of the CoCo. The Video
Display Generator (VDG) chip initializes
itself to either the rising or the falling edge
of the video clock at any power up or reset
cycle in a manner that is both random and
can neither be detected nor affected by
software. This determines whether your ship
will be red or b|ue (and whether the back-
ground will be blue or red!). There is no way
to predict or control which set you will get
unless you make some very sophisticated
hardware modifications.
• When running artifact color programs
like Black Sanctum awiPitstop II, my CoCo
2 presents a red and green artifact color set,
not the red and blue set the game's instruc-
tions say I should have. Is something wrong
with my computer?
Todd A. Black
Merced, CA
Before I can tell if something is wrong
with your computer, I'd need to know if you
are using a TV or a monitor. Have you tried
adjusting the tint control on your TV or
monitor? You might be able to adjust it to
become red-blue using the tint control. If
not, you may have a problem in your TV,
monitor, computer or, most likely if you are
using one, your color video monitor driver
circuit.
• My Extended BASIC 64 K 4 F' board com-
puter loses all color when I press Reset.
Replacing the VDG chip did not help. 1
damaged the "flying circuit" in the plastic
tube while I was working on my computer.
The colors I do get are now strange. This
circuit is not shown in the schematic I have.
Do you know the values of the components?
Edwin J. Mullican
Gulfport, MS
The CoCo I 'F' Board is a particularly odd
case, because Tandy went into production
with a board that in most cases simply failed
to produce artifact colors. They had to add
a fix after production of the board; that is
the thing you referred to as the "flying
circuit."
The flying circuit consists of a 33K ohm
resistor, a 27-micro henry inductor (choke)
and a 75-pico farad capacitor all hooked in
series, with one end connected to Pin 33 of
the VDG (the video clock line) and the other
connected to the composite video input to
the Aztec RF Modulator. This point can also
be found on the circuit board as the junction
of R45 (470 ohms) and R45 (1.5K ohms).
The video clock signal can also be picked up
at one end of R37 (10K ohms).
Note that early models of the CoCo I l F 1
board had a different sort of fix: Tandy
merely soldered a 56K ohm resistor between
Pin 2 and Pin 12 of the 1372 chip (U6). You
might want to experiment with using resis-
tors between 33K and 56K between pins 2
and 12 of the 1372 chip. In your testing, be
sure to solder the resistor directly to the chip.
The test won't be valid if you use any kind
of jumper clip cables.
• I am interested in a quality printer that is
both fast and does not produce "dotty-
looking" characters. In general, I have not
seen print quality that I like from less than
a 2 4- wire print head. What do you recom-
mend? I do not want to get involved in
interfaces or DIP switch settings or changes
in wiring.
Dorothy Dow
Jacksonville, FL
Brands to look for are Toshiba and
Fujitsu, both of which, in my opinion, make
better high-end 24-wire print head printers.
Some of the slower Toshibas are offered for
under $600.
There is no way to avoid having to set DIP
switches on printers no matter what printer
or computer you own. Under Disk basic,
essentially all features of any printer except
proportional spacing can be accessed using
Telewriter or VIP Writer. Under OS-9,
Stylograph allows use of proportional
spacing options.
• / own a Zenith 123 A monochrome mon-
itor and a Mark Data Products video driver.
Both work well on my CoCo. The Zenith is
rated at 640 by 200 dots resolution, or 15
MHz band width. I see other monitors
comparably priced rated at 700 by 200 dots
and 20 MHz. What is the best resolution the
CoCo can handle? What do add-ons like the
Word-Pak RS and the DISTO 80-column
card do for the Co Cos resolution?
Bill Condie
Freehold, NJ
All monochrome monitors have adequate
resolution to display the CoCo's Hi-Res
image of 256 by 192 pixels. Indeed, specifi-
cations such as dot resolution and mega-
hertz band width are not good indicators in
determining if one composite monitor is
better than another. You simply must com-
pare monitors with your own eyes.
Both the Word-Pak RS and the DISTO
80-column card have separate video signal
creation hardware that produces a higher
resolution video signal for display of text
(only) in an 80-column by 25-line format.
The DISTO card has the advantage of
supporting underline and boldface display,
and the Word-Pak RS has the advantage of
allowing a hacker to tinker with both its
character set and its display parameters to
match it to odd-ball monitors. Both draw
their characters in a roughly 5 by 7 matrix
on a 640 by 200 pixel resolution screen.
Compare this with the 256 by 192 pixel
matrix that is the maximum a normal CoCo
can display.

J.P.Schreur

I suggest you purchase one of the lower
kit adaptors commercially available. These
are boards that utilize the ability of the old
6847 to derive its character set from an
external character generator EPROM. One
is made by Green Mountain Micro of
Roxbury, Vermont. It offers the advantage
that you can reprogram the character gener-
ator EPROM with your own character set
of choice.
• I need to purchase a color monitor. While
referencing ads in rainbow I see that some
monitors do not have a Hi-Res dot-matrix

would change the Hi- Res dot-matrix from
255 by 192?
Charles Stierhoff
Dallas, TX
Essentially, any make or model of com-
posite color monitor will work fine on the
CoCo. The ads that claim a given dot
resolution merely refer to the maximum
possible resolution the monitor can display.
Thus, a monitor rated at 300 by 300 will
nicely display the 256 by 192 CoCo Hi-Res
screen. I do not believe there is a color
monitor with resolution below 256 by 192.
• I purchased a 16K standard BASIC CoCo
2 and upgraded it to 64K ECB myself. I
[later] purchased a second CoCo 2 l6Kand
when I went to upgrade it to 64K ECB I
found the PC board had changed. The PC
board we have is Revision F. When I talked
with the Radio Shack Computer Center they
told me this board is [difficult] and costly to
upgrade — the price is $120. You can
purchase a CoCo 2 64 K ECB for about $150.
The price to perform the upgrade does not
make economic sense. Is there a solution?
John Huth
SCS, MI
It would have helped if you had given the
catalog number of the CoCo 2 you want to
upgrade, but it sounds like an A or B model
(number 26-3134A or 26-3134B). Inside this
model are two (not eight) socketed RAM
chips, usually flanked by two white single
inline female connectors. Each of these chips
(numbered 4416) has a total of 18 pins, not
16 like the RAM chips in older CoCos. They
are found more or less in the center of the
circuit board.

submission, Open Arms, is a darn good
one.
The CoCo SIG staff heartily thanks all
members for their contributions to the
database.
A Look Back and a Look Forward
Our database has been steadily grow-
ing. The largest growth has been in the
Graphics section, with the Utilities sec-
tion close behind. Ira Goldwyn, a long-
term CoCo BBS user, has amassed an
immense library of Color Computer art,
consisting of original art, cartoons and
digitized pictures. He has contributed
heavily to our Graphics database. Ira
says he has over 2,000 CoCo art files in
his library. I expect well be seeing quite
a bit more from him. Soon, we expect to
have the rainbow's "CoCo Gallery"
pictures in the Graphics section, availa-
ble to members without surcharge.
The labors of our new OS-9 section
leader, Steve Bjork, are beginning to be
felt in the OS-9 database. OS-9 files are
now promptly enabled. Steve has worked
closely with some of the more recent
contributors to improve their files. Ar-
rangements are now in progress for
software from the OS-9 users group to
start appearing in our OS-9 library. And
the "KISSable OS-9" program files from
rainbow will soon be available in the
OS-9 Data Library section, though ac-
cessing those "KISSable OS-9" files will
incur a $3.50 surcharge, as is the case with
regular RAINBOW on tape material.
Members will be alerted to this by a
dollar sign ($) in the filename.
Soon, I hope to find time to upload all
of the WEFAX program material I have
in my personal library, including a dozen
or more graphics files of the documenta-
tion for WEFAX, hand-drawn by the
authors of WEFAX and Graphicom.
Coming from these same folks will be an
RTTY program to allow amateur radio
operators to receive and transmit RTTY
signals using the CoCo, and a Morse
Code practice program that incorporates
all of the latest ideas about how to
properly learn the code and improve
speed. Don Hutchison (DONHUTCHI-
SON) will soon be uploading some useful
schematics and associated documenta-
tion for simple, rugged disk drive power
supplies to the Hardware Hacking sec-
tion. He and I have been working on
these fo r the last few weeks, collaborating
via Delphi Mail. I may also have time to
upload some more font sets for Graphi-
com. I plan to write some new product
reviews, including a comparison of all
available 256K RAM disk upgrades for
the CoCo, and a comprehensive product
review of the new DS 69 A video digitizer
from Microworks, which is a most im-
pressive product.

elphi's way of saying you can down-
ad or list the file now. If you press
^TER at this prompt, the information
}out the next group in the directory is
:nt to your screen.
eady to Download
To initiate an XMODEM download,
'pe XM. You are prompted with:
jpe three consecutive <Control-
>'s to abort.
K, receive! (text)
In this case, the file is an ASCII file
s indicated by "text" in the above
xample. If the file is binary, "text" is
eplaced by "blocked." At this point
nitiate XMODEM receive on your
srminal program. On Mikeyterm, this
5 done by using CONTROL-'4\
The file should begin transfer into
our computer. When transfer is com-
pete, your terminal program prompts
'ou. Save the file to tape or disk. It is
vise to look at the contents of the buffer
irst. If you can read each character in
he buffer, the file should be saved as an
\SCII file. If, however, the buffer
contains what appears to be graphics
characters and other "garbage," the file
s in binary (not necessarily machine-
anguage) and should be saved accord-
ingly.
To initiate an ASCII download, type
DOW at the RCTION> prompt. Delphi
responds with:
3eady Press RETURN to begin:
At this point, open the buffer on your
communications software and press
RETURN. As the file is transferred, you
will see its contents scroll down the
screen. Since binary files cannot be
transferred in this manner, remember to
save the file to tape or disk in ASCII.
Final Notes on Downloading
That's all there is to it! Once the file
is saved, simply return to the commun-
ications mode and continue having fun.
If the group from which you down-
loaded contains more than one file, you
will probably want to get others, too.
When you return to communications,
Delphi will still be just "sitting" there.
If you press ENTER, Delphi responds by
starting a transfer of the next file in the
group. If the group only contained one
file, when you press ENTER, Delphi
responds by sending the information for
the next directory group to the screen.
This is handy for downloading several
consecutive files and groups.
If there is more than one file in a
particular group, you don't have to
download the third file listed in the
group, for example, just type XM 3 or
DON 3 accordingly at the RCTI0N>
prompt.
To return to the database prompt for
the database you are in, use CONTROL-
4 Z\ To change to a different topic area,
type SET XXX where "XXX" is the first
three letters of the database area you
want.

Steve Bjork (6809ER) has contributed
a random number generator in assembly
language source code to our Source For
6809 Assemblers topic area. Steve, one of
the best known CoCo games pro-
grammers has, over the last year, been
producing a lot of code he has been
placing in the public domain. His excel-
lent Mouse utilities have been appearing
in the pages of RAINBOW over the last
couple of months. I have uploaded to the
Source For 6809 Assemblers area the
source code file for the MSI 9 SET form at
program that allows a CoCo to format
MS-DOS type disks. This code is highly
commented, and while written to create
a single-sided MS-DOS disk, can easily
be modified to generate double-sided
MS-DOS format. Art Flexser (ART-
FLEXSER), author of ADOS and
Peeper, has continued to upload more of
his tutorials to the Source code section.
Among them is a tutorial on how to
program the PIAs of the CoCo to read
the keyboard and an introduction to ML
sorting.
Our Utilities section has been expand-
ing with new files from many members.
Mark Kowit (TOBOR8) has uploaded
Real Estate Management and Evaluation
programs. Jim Manning (JIMBM) has
uploaded a Homebudget program, and
Bill Lippert (BEERBELLY) has given us
archiving older polls. To see the ar-
a delete disk file utility Milton Webb
(MILTWEBB) contributed a disk utility
program, and Paul N or m and (PAUL-
NORMAND) has provided a program
for cataloging video tapes (BETA. BA S).
Chris Bergerson (CHRISB) donated a
Disk Label Maker utility.
In the Hardware Hacking topic area
Steve Bjork has uploaded a utility for
checking out the memory in a DISTO
RAM Disk card. IVe uploaded an article
on how to upgrade all models of CoCo
2, and one discussing the use (and abuse)
of high speed pokes on the CoCo. I also
have uploaded a technical file for owners
of the J&R Banker on how to fix the
hardware so youll never have to disable
the unit to run any CoCo program. This
hardware fix cures the unit's problem of
not working with programs that talk to
the SAM using CLR instructions. Fi-
nally, I have uploaded some alternate
fonts for burning into 2716-1 EPROMs
to improve the appearance of the char-
acter set of the PBJ Wordpak-RS. In-
cluded are utilities to create your own
fonts.
In the Graphics database, there is a
staggering number of new and lovely
uploads Stephan Macri (DR ACM AN)
has given us a utility to convert the
output of the C64 Doodle converter into
CoCo Max file format. Mark Kowitt has
provided us with a beautiful enhanced

DELPHI BUREAU
Using the CoCo SIG
By Cray Augsbur
Rainbow's CoCo SIGo
User Name: RAINBOWMA
Let's take a trek into the workings
of the database on the CoCo
SIG, and while we're on this
voyage, we'll look in detail at how to
download and upload files while on
Delphi. However, we first need to
become more familiar with the funda-
mentals.
File Formats
A file is a group of related characters
and symbols. Generally the term "file"
refers to a program, an article or a set
of data. There are two different formats
for the storage of information in files:
ASCII and binary. Binary files are
sometimes referred to as compressed or
tokenized. An ASCII file contains
readable characters, while a binary file
contains characters that represent the
zeroes and ones the computer works
with.
ASCII is the preferred format for text
files or articles. It is sometimes best to
store BASIC programs in the ASCII
format. Incidentally, we request all
BASIC files for uploading be stored in
ASCII. Binary is used for the storage of
tokenized BASIC files, machine language
programs, graphics and music files.
Infrequently, text files are stored in
binary format.
File Transfers
There are two distinct methods of
uploading and downloading files. These
are the ASCII transfer method and
XMODEM transfer. While the ASCII
transfer can only be used to transfer
ASCII files, XMODEM can be used to
transfer both ASCII and binary files.
Cray Augsburg is rainbow's technical
assistant and has an associate's degree
in electrical engineering. He and his
wife, Ruth Ann, have two children and
live in Louisville, Kentucky. His user-
name on Delphi is RAIN BOW MAG.
ASCII transfer is simply the trans-
mission or reception of a character-by-
character image of a file. Since the
ASCII code uses only the lowest-order
seven bits of each byte, control codes
and other special information (binary
code) cannot be transmitted in this way.
ASCII transfer involves no automatic
error detection, so it is frequently
unreliable for the transfer of informa-
tion.
The XMODEM protocol transfers
complete bytes and, therefore, allows
the transfer of binary information and
control codes. When a file is being
transferred via XMODEM from a host
computer to a remote computer, the
information is sent in groups (blocks) of
128 bytes rather than a continuous
stream. This allows for error detection
in the transfer.
Once a block is transferred, the host
computes a checksum value based on
the information contained in the block.
The remote computer also does this,
and sends the value back to the host.
The host compares the computed values
and, if they are the same, transfers the
next block in the file. If the values do
not match, the host knows the sent
block was not correct and resends the
block. Most XMODEM terminal pro-
grams allow the host to send a correct
block up to 10 times, if necessary. This
allows for the transfer of error-free
ASCII or binary files. It is for these
reasons we suggest you use a terminal
program that includes XMODEM ca-
pability. If you do not have access to
one, you can download Mikeyterm
from the data communications data-
base via ASCII transfer. Mikeyterm is
an easy-to-use XMODEM terminal
program that supports several system
configurations including tape-based
systems.
Database Organization
The CoCo SIG database can be
viewed as a room full of file cabine
There are 16 file cabinets; one for ea
topic area of the database. Each cabir
contains several drawers (we call the
groups on Delphi.) Each drawer c.
have one or more folders (files,
programs) in it.
Type DAT to get the database for t
CoCo SIG. You will see a TOPIC
prompt; enter the name of the topic ar<
you want to peruse (see Table 1.) R
member, Delphi allows you to enter tJ
first few unique characters in place
the entire name. A shorter method is
include the topic name on the commai
line with DPT. For instance, at the CoC
SIG prompt type DAT GAM to enter tl
games database.

Now, you can supercharge Basic with an impressive array of extra features
WITHOUT sacrificing compatibility! ADOS Is compatible with virtually 100% of
commercial software. Customizing utilities are provided to allow user-defined
command abbreviations, baud rate, step rate, tracks per disk (35 or 40), support of
double-sided drives, and more. After customizing ADOS, you can have it burned Into
an EPROM that plugs into the Disk Basic ROM socket, or just use it in RAM as a 64K
disk utility. {EPROM + burning will cost about $20-we provide information
concerning how you can have this done.) Features include: • repeat and edit of the
last direct-mode command » 26 definable control-key abbreviations • automatic line-
number prompts • DOS command • lowercase command entry (a fine complement to
a lowerHit or PBJ WordPak) • COPY (filename) to (drive number) • AE error override
option • RAM command (64K) • RUNM command • text echoing to printer • ML

must enter the correct digit number to
get a correct response. Keep in mind
that the number entered must not have
any commas in it. After a response has
been given, you may press '(§)' for the
score, but not during the input part.
Otherwise, the '@' symbol is interpreted
as an incorrect response.
When you finally go to the score card,
either press 'C to continue, *Y' to run
the program again, or 6 N' to end the
program.
The program should fit easily into a
16K CoCo, but if you have any doubts,
PCLEAR1 first. You could also include
the speed-up POKE as one of the lines,
but quite honestly, the program runs
rapidly enough as it is.
A Few Words About Title Maker
I have gotten letters from a few
people who have had difficulty with the
CoCo Title Maker from several months
ago. While I don't have the time for
individual replies, this should cover
most of the concerns.
First, some have written and asked if
there were any mistakes in the listing.
No, the listing is without error. Some of
you may have made typing errors when
keying it in. When in doubt, subscribe
to RAINBOW ON TAPE.
Some have said they get a ?DS error
when trying to reload the BASIC pro-
gram created by Title Maker. This
happens only if you have left out a
semicolon somewhere in the original
listing. Recheck your typing. If that
doesn't work, you could always load the
new BASIC program into a word proces-
sor like Color Scripsit. First try loading
the program into BASIC. If you get the
?DS error, it means you have a direct
statement without a line number. List
what has loaded to see in what line the
problem appears. Then load the BASIC
program into the word processor, and
remerge the lines where this error oc-
curs. Save the result and then relo
into BASIC.
Others say they have gotten the ?I
error when trying to load the new BAS
program from disk. This only happe
if you analyze the screen and then sa
the screen to disk in machine languaj
What happens is that the machii
language screen is saved with a /Bf
extension. Use RENRME to give th
machine language listing a /BIN exte
sion, reload it into the Title Maker, ar
then analyze it to disk. This should sob
this very rare quirk.
As a rule of thumb, it is better to sa 1
first, and then analyze second.
Conclusion
I hope this fourth installment in t\
Life Skills series proves valuable to yc
whether you are a teacher or ha\
youngsters in the family. Keep thinkin
up those ideas, and 111 see what I ca
come up with. See you next month. [

level of the material if the work pre-
sented is either too easy or too difficult
for the user.
To make this program more adapta-
ble, I have limited the basic keywords
to only those found in 16K Color BASIC.
I have also intentionally left out any
keywords which are not found in the
MC-10 Color BASIC language such as
ELSE or STRINGS. MC-10 users should
change the value in Line 235 (235
K = RND ( -TIMER )) to 235 K=RND(-
9999) or some other number. You may
want to insert this value in the middle
of Line 185, too, if you want to make
the program truly random on the MC-
10.
The first task I encountered in creat-
ing this program was to write an algo-
rithm (set of program commands) to
take a number and translate it to its
written form. This requires storing the
names of the numbers in string arrays
and combining them to create the cor-
rect written equivalent.
Naturally, we can't store all the
possible written numbers; our program
would be gigantic. We want to store
only those root parts to be combined as
needed. For example, we dont save a
string as sixty-three but combine the
strings for sixty and three to form our
answer. Therefore, the DATA statements
contain all our possible written roots.
The next trick is to devise a way to
create multiple-choice answers for a
randomly generated number. However,
since we need to deal with our numbers
in their string form, a strange bug in
BASIC caused me many hours of head
scratching. It seems that every now and
then, if we are dealing with STR$ and
the VAL(X$) commands, basic decides
to add a useless decimal tail to our
number. Therefore, our string number
of 23.56 may end up appearing as the
mutant form 23.560001 when displayed
on the screen. This causes great confu-
sion to our user, so I had to find a way
to chop off this tail whenever it appears.
After some trial and error, I was able
to come across a set of lines to do just
that. You may notice that the com-
mands to create and analyze the
numbers and strings are longer than
necessary and may cover circumstances
which our random numbers may not
require. This was necessary in order to
make the algorithm work.
These lines soon expanded into a full-
blown program of 170 program lines.
Funny how a simple idea can be ex-
panded to such a degree. These are the
steps we must take, however, in order
to cover all the circumstances we want
our program to deal with.
The earliest version of this listing
incorporated this CPL concept only if
the student checked his progress. Since
my recent programs have allowed the
user to check progress, then continue,
I have found many students will check
their progress every two minutes. I felt
this would be a way to discourage that
practice by having the difficulty level
increase if the score was above 95
percent, or decrease if it was lower than
70 percent.
This did not prove suitable in cases
where the student did not check the
progress by pushing the *@' key. There-
fore I included a routine to check the
progress, without displaying it, every
ten problems. If you want to change the
minimum and maximum scores which
trigger the change, alter the values of 70
and 95 in lines 795 and 805. The variable
'MS' stands for the Math Score for the
program at that point.
The result of these line changes is that
the student can be using the program,
reviewing the material, and the program
will vary the skill level to match the
student's ability. Thus, if a student is left
on autopilot, (which I do not advise),
there is less likelihood of wasting time
on unsuitable material
If our program generates a number to
be identified and has to create multiple
choice answers, it usually generates
them by moving the decimal place to the
left or right. Some students noticed a
pattern in my earliest version so I later
included commands to break this pat-
tern. Therefore, if a zero appears in the
tenths place, one of the multiple choice
answers will extract the zero. This
allows us a truly random creation of
multiple choice responses. This extrac-
tion occurs in about half of our cases.
One option I have avoided is having
the user enter a written number to
match a number in digits. This would
cause great confusion as the user might
include an extra space or misspell one
of the root words. For example, if an
answer is one hundred and twenty-on
hundreths, but was entered as one
hundred and twenty one hundreths, i
would be marked as incorrect. This onl;
frustrates our student.
Recently I was presenting some of m;
earlier educational programs to a grouj
of teachers in a private school when on
of them expressed concern over m;
program's use of the word Wrong whei
an incorrect answer was used. Shi
asked, "Couldn't you say Sorry instea(
of Wrong? Wrong sounds so negative.
Therefore, I have started using Sorn
when an incorrect answer is entered.
Using the Program
On running the program, our Lift
Skills title card appears. I have tried t(
use a different color scheme with eacl
one. You are asked to select a skill leve
from one to five with one being th<
easiest level. If a higher level is selected
it continues to select problems from ar
easier level as well in order to allow foi
greater variety of selections.
Your next choice is digit or written,
Choosing ' W displays a number thai
must be idenitified from the two choices
listed below it. For example:
HOW WOULD YOU WRITE OUT THE
FOLLOWING DIGIT ?
72.41
Pi) SEVENTY TWO RND FORTY ONE
THOUSfiNDTHS
B) SEVENTY TWO RND FORTY ONE
HUNDRETHS
The user must press either *A' or 4 B'
to respond. Pressing *@' gives the user
a score card.
If 'D' is selected for digit, then there
are two possible choices, either select or
input.
The Select mode offers multiple
choice digit answers to a written
number. There may be anywhere from
two to five multiple choice responses
displayed, depending on the difficulty
of the material. Pressing '(a)' gives the
score card.
If you choose the Input mode, then
a written number is displayed. The user

Computer- Paced
Learning

the "Wishing Well/' submit it to Fred
c/o THE RAINBOW, Remember, keep
your ideas specific, and don '/ forget that
this is BASIC. All programs resulting

time passes, and more and
more programs are written
for our Tandy computers,
software authors discover new uses for
the BASIC language burned into the
chips of our machine's ROM. This
month's "Wishing Well" offering is no
exception as we will introduce a new
concept to our pages: CPL or Computer
Paced Learning. This is done with our
fourth Life Skills program titled Writ-
ten Numbers.
The Wish: What is CPL?
More classrooms now have computer
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.
terminals in them. Teachers across the
country have purchased millions of
dollars of software and have quite often
been cheated out of their school dis-
trict's limited financial resources. There
have been two very serious drawbacks
to this development.
First, some school districts have
joined in a game of one-upmanship by
comparing expenditures on computers
and software as if they were comparing
new cars. This type of attitude can have
a very negative impact on the goals of
any computer program. What is needed
is software geared to specific needs.
The second error that occurs is the
tendency to put students on "autopilot"
once appropriate software is found.
Some students will gladly work on a
program covering material too easy for
their ability. Unless the student's level
and progress are closely monitored, the
student will drift off, running like a
plane on autopilot, oblivious to all real
learning.
Since we have a CPU (Central Pro-
cessing Unit) in our machine capable of
executing any logical command set
given it, we can develop, with a little
care, software which just might help us
deal with these two problems. That's
where the concept of CPL or Computer
Paced Learning comes in. Our goal is to
have our software actually monitor the
student's progress during the running of
the program and make adjustments in
skill level based on that student's per-
formance.
The Program: Written Numbers
Our first Life Skills program was a
simulation that dealt with money hand-
ling skills and subtraction. Our second
program was Number Evaluation in
which the place value of numbers was
examined. Program three dealt with
Ruler Reading Skills. In Written
Numbers, however, we return to the
math skills originally introduced in
Number Evaluation. Rather than iden-
tify the place in a number as was done
in that program, this time we want to
evaluate a number such as 55,697.25
and translate it to its written form of
fifty-five thousand six hundred ninety-
seven and twenty-five hundreths.
The first requirement of the program
is that it have a variable skill level which
can be selected from a menu. Next, it
must deal with an evaluation of the
numbers in both written and digit form.
Third, it must allow for periodic check-
ing of student score and progress.
Finally, it must adjust the difficulty

TEXTPRO III is an advanced word processing system designed
for speed, flexability and extensive document processing. It is not
like most of the other word processing programs available for the
Color Computer. If you are looking for a simple word processor to
write letters or other short documents, then most likely you'll be
better off with one of the other word processors. But, if you want a
powerful word processing program with extensive document
formatting features to handle large documents, term papers, man-
uals, complex formating problems and letter writing, then TEX-
TPRO is what your looking for. TEXTPRO works in a totally
different way than most word processing programs. It uses simple 2
character abbreviations of words or phrases for commands and
formatting information that you imbed directly in your text. There
are over 50 different formating commands you can use without ever
leaving the text your working on. There are no time comsuming,
and often furstrating menu chases, you are in total control at all
times. The formatted output can be displayed directly on the screen,
showing you exactly what your printed document will look like
before a single word is ever printed. This includes margins, head-
ers, footers, page numbers, page breaks, underlining, column
formating and full justification.

The art of entertainment
Pinball Factory by Kary McFadden
The video game comes full circle in this glorious tribute to the original.
Classic pinball spings to life as never before, with fresh new angles that
only the computer can offer. Crisp graphics, sound, and fast, smooth
action give this machine-language arcade game a realistic, responsive feel
you'll hardly believe. There are even "tilt" buttons that let you "bump"
the machine!
In addition to playing a great game of pinball, you can enjoy hours of
creative pleasure as you design, build, and edit your own screens. Save
and load your favorite creations. The joystick-controlled cursor makes it
all easy.
Change the board: build with bumpers, tabs, and a multitude of solid
obstacles to form any configuration imaginable.
Change the face: draw your own title board with lines, rays, and shape
patterns. Add text in three different colors, and two dirrent sizes.
Change the rules: alter the gravity, bounce, and scoring!

by the value of the spin multiplied by
the number of times the letter appears
in the puzzle.
After the final round is played, the
computer displays the scores from
highest to lowest. If all consonants are
shown before the puzzle is solved, the
computer asks for the solution to the
puzzle. If no one guesses correctly, then
it displays SORRY NO WINNERS THIS
ROUND and advances to the next round.
Listing 1 , Fortune Wheel, is the main
game. Listing 2 is for creating puzzle
and category files for Fortune Wheel.
When keying in Listing 1 be careful to
space it just as it is in the listing. If you
don't space correctly, you will get an SN
Error. Be sure to type in both listings
and save them on disk before using
Listing 2 to create the puzzle file. This
listing creates direct files and it will
write on top of any file or program
saved after establishing the puzzle file.
This should be a dedicated disk.
This game will only run on a 64K
Extended BASIC machine. It uses direct
access files so it works only with a disk
drive. If you want to use it with a
cassette, you need to modify lines 580
through 620.
I have used the speed up and slow
down pokes (POKE 65495,0 and POKE
65494,0) in several places in the pro-
gram. I found that you must use them
in lines 580 and 620 because these lines
are in the retrieve record routine.
One final note on Listing 1: In the
alphabet DATfi lines, I have created a
data record for the computer to draw
every alphabet character (true upper-
and lowercase) and all the punctuation
characters on the keyboard. So when
using Listing 2 to create puzzle and
category records, feel free to use lower-
case letters and punctuation.
When you load and run the program,
a menu appears giving the options to
Create Records, Correct Record, List
Records and End. When creating rec-
ords, the computer enters a short word
processing routine that allows you to
type in a puzzle record up to 64 char-
acters long. Once the record is the way
you want it, press ENTER. The Enter
Category menu pops up giving the
choice of phrase, title, place, person,
president and Bible phrase for catego-
ries.
If you choose the Correct Record
option from the first menu, the compu-
ter asks you to enter the number of the
record you want and retrieves the rec-
ord so you can correct it. After all
corrections are made, press ENTER and
the Enter Category menu pops up again
for you to enter the record category.
If you select Option 3 (List Records)
the computer asks if you want a hard
copy. Next it asks you to ENTER RE
CORD : STRRT , END. Just enter the
number for the first then the last record
to be listed. The computer will list the
records on the screen and printer.

GAME
Fortune Wheel
This challenging
game provides fan
and excitement for
the whole family
By Arron W. Branigan
ant to play a great family game? Then
Fortune Wheel is for you. This game is
fun for the entire family; up to 10 people
can play at once. If you don't have anyone to play with
you, it's just as fun to play by yourself. This game is very
exciting — from the exhilaration of guessing the puzzle to
the frustration of going bankrupt.
When playing, the computer prompts are self-explanatory.
When starting a game the program asks for number of rounds
and players, and the names of the players. The screen then displays
PLEASE WAIT WHILE I CREATE GRAPHICS. The title screen soon
appears. Press any key to begin the game.
The program retrieves a record for round one then sets up the
screen. A menu appears allowing you to solve the puzzle, buy a
vowel or spin. Select 1 to solve the puzzle (if you guess correctly,
your score is multiplied by three and the game proceeds to the
next round or end routine). Select 2 to buy a vowel ($25). Select
3 to spin.
If you choose to spin, you are asked to enter a consonant.
If the letter selected is in the puzzle, your score is increased

can also be used to set up custom reports, print mailing
labels, etc. The limits seem only to be in the user's ability
to program in basic. Action templates could even be used
on data files created by other programs if the user has
sufficient experience.
One of the other major differences between CoCo Base
I and other database managers is CoCo Base A ability to
create and execute batch files. These are created using
Schedule and executed using Jobs. Schedule creates a job
file of Action templates. Schedule allows the user to specify
the templates to be used as well as the order and type of
execution of these templates. For example, a report could
be produced by using one template to print a header, the
next to find, format and print a list of selected records, and
a third to print a footer and totals. Templates can be
executed once, once for each record in order, or once for
each record in indexed order. Since templates can contain
many lines of BASIC code, each one can be quite complex.
Two final options are of interest to those who need to
construct new databases from old ones, those who want to
create very complex databases, or those like me who
invariably enter large amounts of data into a database
before they realize that the data structure is wrong. Transfer
creates a new database which includes data from an existing
database file. Additional fields can easily be included in the
new database format, so additional fields can be added to
a database. This feature alone could save countless hours
of aggravation and programming. I always seem to need just
one more field in any database I create after it is in use.
Update gives CoCo Base I its claim to being a relational
database manager. Update does not access several different
related data files at once. Instead it moves selected fields
from one data file to another. This requires that each of the
files has a field common to the other. Update places fields
in the correct record in the receiving database by looking
at this "related field." Of course only one related field is
used.
This ability to combine data from several data files is
useful for a number of things. To me, the most important
use is in keeping individual files short and combining
information from different files later when the combined
information is needed.
If you get the feeling that I am impressed with CoCo Base
I you are correct; it fits my needs quite well. However, it
has a few problems. First is error handling. There are

instructions in the manual that tell you what to type in case
of an error. This works and is adequate, but it is inelegant.
There should be some way of trapping errors before they
dump the user back to the OK prompt. Another annoyance
was with CoCo Base A inability to allow a record to be
removed from a database. There are many times when a user
would like to delete a record from a file. CoCo Base / does
not allow this in a simple way.
The last complaint has to do with nearly every database
management system I have used. I have to keep telling the
program the name of the files I am working on. I realize
that this is the price one pays for having the ability to store
different versions of each file, index, etc., but I still find it
a nuisance. Unfortunately, if this "problem" is fixed it would
have to be at the expense of flexibility. Given the choice,
I'll vote for flexibility.
The last comment I have is not so much a complaint as
a suggestion to potential CoCo Base / users. Learn BASIC.
Although CoCo Base I can be used by any non-
programmer, the power of the program is best released by
someone familiar with BASIC. You could learn BASIC as you
go, but previous knowledge is extremely helpful. At first the
program may seem weak or difficult to use, but after some
practice I find that it can do a great many powerful and
useful things.

Software Review ^S^SS^SSSSSSSB^N
Powerful CoCo Base I
is Full of Surprises
By D. McGarry
CoCo Base lis the latest offering from JTJ Enterprises
of Nashville, Tennessee. I mention this because there is a
strong family resemblance between CoCo Base / and CoCo
Solver, JTJ's other product. Several neat programming
tricks were included in both programs and both use the same
machine language data entry editor. CoCo Base / stands on
its own as a good, solid database program. If, however, you
own and use CoCo Solver you will be able to extract
maximum performance and flexibility from CoCo Base I
with less effort than someone with no prior experience.
Several features help CoCo Base I to stand out from the
crowd of other database management systems. First, CoCo
Base lis a relational database manager. This means that it
can access more than one data file by referencing a field
common to all files. Second, through the use of Jobs and
Schedule options it allows the processing of batch files.
Third, the Action option allows for the inclusion of BASIC
statements to manipulate data.
CoCo Base I comes on an unprotected disk which
includes 10 program files and several sample files. All work
is started by typing RUN "MENU" at the OK prompt. Menu
options are Create, Put, Index, Action, Schedule, Jobs,
Transfer and Update.
The first step in creating a database is to use the Create
option to create a structure file of the data fields. Each field
is given a two-character name, description, length and type.
Field types can be either character or numeric. The structure
file can be edited at any time and can extend over several
screen pages allowing for large or complex records.
Once the structure file is saved, the Put option is used
to add, edit, find and print records. Put uses the structure
file defined with Create to show records and for data entry
Put can use an existing file or create a new one as records
are added. This allows the creation of several database files
which all use the same data format.
The next option is Index which does exactly what the
name implies. Index files can be saved with their own names,
so several index files can exist for the same data file.
Up to this point, CoCo Base / looks and acts similar to
most database management systems. The additional
options make CoCo Base I different from any other
database manager I have used.
The most unusual and powerful uses of CoCo Base / start
with the Action option. Action allows the creation of
template files which can act on the database. Templates are
sets of BASIC language statements that are added to the
Action program as it runs. Action statements can be used
to do nearly anything to the data file as far as I can tell.
I used Action templates to average a set of grades for one
of my physics classes. The grades each had a weighting
factor. Some of the grades were numeric and some
alphabetic. Even though it took some experimentation to
get the template correct, Action allowed me to do this job
more quickly than any other method I have used. Action

CoCo Keyboard
Beats the Chiclets
Imagine . . . could someone actually like the "chiclet"
keyboard on their 6 F* board CoCo? I did. I was accustomed
to using that keyboard and I can hunt and peck with the
best of them. Well, all that changed when I received my
review assignment for the replacement keyboard offered by
Spectrum Projects.
I received the keyboard and immediately installed it in
my Color Computer. The documentation was brief and
appeared incomplete. Nevertheless, replacing a keyboard is
perhaps one of the easiest upgrades to perform on a CoCo.
To make it even easier, the keyboard is the same as the 26-
3016 keyboard retailing for $24.95 at Radio Shack (less
installation). This means there is no cutting or soldering
involved at all.
Simply open the case (keep in mind this voids your
warranty), unplug the old keyboard, plug in the new one
and close the case. That's all there is to it. After that, you
have a keyboard with full-size keys and a better overall feel.
I found it very easy to get used to the new keyboard.
Particularly since the key placement is the same as on my
old one, but the new keyboard feels better and typing goes
a lot smoother. Even touch-typists should like this keyboard
more than some others on the market.
The keyboard is designed to fit into any revision of Color
Computer from the old *F' board to the present CoCos. The
cable is the transparent, super-thin mylar conductor type.
If you have a version earlier than the S F' board, Spectrum
also sells an adapter that allows you to easily install the
keyboard in your computer as well. Keep in mind, if you
have one of the newer CoCo 2s this is the same keyboard
you already have.
I highly recommend this keyboard for anyone and
everyone. Its low cost as well as ease of installation make
it one of the best upgrade buys on the CoCo market today.

No Frills U-Ruff
is an Excellent Value
As much as we hate to admit it, the present-day world
puts much emphasis on time. Hurry this and hurry that; it
is as if we were in a race to the finish! Well, the U-Buff printer
buffer from Digital Devices fits in nicely.
I have given this little gem a thorough run for its money.
Over the last month and a half, I have sent it files from
Delphi, files from my word processor, data from my BASIC
programs and graphics. It hasn't let me down yet. It has
always printed each character reliably.
For those who don't know, a printer buffer is nothing
more than a go-between. It goes between your computer and
printer. A printer is limited in speed. The print head can
only move so fast across the page. However, a computer
can send data much faster. So the buffer allows the
computer to finish sending its data more quickly. Therefore,
you don't have to wait all day for the printer to finish before
going ahead with your work.
As an example, when I told my system to print a 40. 5K
file, the prompt was back on the screen in 83.5 seconds. I
was already involved in my favorite game when my printer
finished printing out the 30 double-spaced pages 15 minutes
and 53 seconds later.
The U-Buff is available in two configurations: 16K
memory and 64K memory. A nice added feature is the
average user can upgrade the unit from 16K to 64K by
himself. The manual gives information on what chips to buy
and how to install them properly. The only drawback is that
the one-year warranty only applies to the configuration
purchased from Digital Devices. Still, I believe this is very
reasonable.
The buffer is designed to accept input from any computer
having a Centronics interface. Since my serial/ parallel
converter terminates in a Centronics plug, I had no
problems. The unit also terminates in a Centronics plug for
the printer's parallel port.
The U-Buff comes with a 14-page, easy to read pamphlet.
The instructions cover installation, testing, troubleshoot-
ing, upgrades and a whole slew of technical information plus
a glossary.
Despite its usefulness, keep in mind a printer buffer isn't
for everybody. But anyone with a business or who does a
lot of printing will surely welcome anything to help them
out.
The U-Buff is an excellent, no-frills printer buffer. For
the reasonable price it is a good work horse with a good
deal of backing from the manufacturer. This one gets four
stars.

formatter we published recently, or the
TSWord formatter. The Desk Mate editor is
very easy to use and a nice way to enter text.
Add the dot commands required by
TSWord or other formatter and you can
print it in any way you like.
Many people also like TSEdit. It is based
on the UNIX VI text editor and does an
excellent job. The only reason I haven't
bothered to use it is the fact that my fingers
already have the DynaStar diamond mem-
orized. 1 would hate to have to learn to touch
type all over again. Yet, a friend of mine
really likes TSEdit. He learned to touch type
on TSEdit first. He enjoys working with the
TSWord formatter but he has discovered
one problem. I have confirmed the problem
but still haven't figured out a solution. If you
come up with one, please let me know.
Since memory is limited, divide the writ-
ing into shorter files and use TS Word's .NX
command. That's fine. In fact, it's a good
way to work, even if you don't need to.
Unfortunately however, TSWord breaks to
a new page every time it hits an .NX com-
mand. What we need is a way to disable this
page break so we can print continuously one
page after the other. Here's an example you
can use to print three individual files at one
time.
,nx part_one
,nx part_two
,nx part_three
Many people on the CoCo SIG forum
seem to believe DeskMate files are not
compatible with other OS-9 programs. Not
so. The secret can be uncovered in the
documentation for the terminal program in
DeskMate. The DeskMate editor automat-
ically adds an extension, .DOC, to the end
of the filename. Therefore, if you save a file
named "Column" it will actually be named
"Column.DOC." Save a DeskMate file then
exit and run the dir utility. Then, go ahead
and list or dump the file using the complete
filename. It worked, didn't it?
The reverse is also true and you could
build a file and then edit it with the Desk-
Mate editor if you give the file you are
building a .DOC extension. For example:
OS9: build Example . DOC <ENTER>
While we're still talking about DeskMate,
we should clear up another point. The
DeskMate terminal program requires you to
use the Deluxe RS-232 Pak. You cannot use
the /Tl port on the back of the CoCo.
Again, bit banging just doesn't work in a
multi-tasking environment. If it did, the
DeskMate programmers would have pro-
vided the option to change it. They clearly
state that you need the hardware AO A in
the DeskMate manual.

an IBM-compatible disk and carry it to
work. In fact you can often get a lot more
work done when you get away from the
constant interruptions of the workplace.
We owe our new freedom to James
Hornsby, who has developed a set of utilities
to let you read or write standard Radio
Shack DOS single-sided disks as well as
standard IBM PC single-sided disks. They
use Dan Johnson's Color Computer OS-9
SDisk driver and can also read and rename
files on double-sided IBM PC disks. Since
they run in OS-9 they also let you send OS-
9 files to either Disk basic and IBM PC
disks, or vice versa. They are most useful for
transferring standard ASCII data files.
Additionally, if you save a basic program
in ASCII and transfer the file to the other
computer, it should load without a problem.
Sequential ASCII text files from Disk
basic load into IBM PC editors without a
hitch, although you have to add line feeds
after each carriage return when using some
editors. When you move ASCII text files
from an IBM to the Color Computer, you
must strip off the extra linefeeds. Hornsby
gives you two utilities, addlf and striplf to
take care of these jobs.
All of Hornsby's utilities use OS-9's
standard input and output path. This means,
their output can be redirected to a file or
used in a pipeline. If you avoid using pipes,
you can even run these transfer utilities on
a single-drive system. A typical single-drive
command looks like this:
0S9: RSread -s #10K /d0/f ilename . dat
>/ dj?/ do cumen t s /my f i 1 e
Here is a typical command line that uses
a pipe.
0S9: RSread /dl/f ilename. ext ! addlf
When you run this command, RSread
reads data from a standard Color Computer
disk and writes it to OS-9's standard output
path. But the pipe, noted by the exclamation
mark (!) diverts this output to the input of
the next program in the pipeline, addlf. The
latter command adds a linefeed after every
carriage return and sends its output to OS-
9's standard output path. Since there are no
more pipes and the standard output has not
been redirected, the output of addlf appears
on the terminal. Programs that work like
addlf and striplf are called filters.
To copy a file to an IBM disk use a
command line similar to this:
0S9: PCWrite /Dl/letter . txt
</d0/letters/myletter
Notice that PCWrite gets its input from
a file named myletter, in a directory named
letters on a disk mounted in Drive /dO. It
does that because the standard input path it
reads has been redirected to receive informa-
tion from the file. It stores the file letter in
an IBM file named letter.txt on a disk
mounted in Drive /dl.
In addition to the standard read and write
operations, you can also format IBM disks
and delete or rename IBM files with addi-
tional utilities in the package. Be careful
with IBM filenames containing the charac-
ters special to the OS-9 Shell — !, # and &.
You can only access files stored in the root
directory of an IBM disk that uses hierar-
chical directories.
This Month's Listings
Gregory A. Law, who has contributed
several OS-9 tips in the past, has contributed
his version of Dennis Derringer's Pager. B09.
The program first appeared in MOTD
several months ago. Law modified the
program to make it print 66 lines per page,
rather than 67 and taught it to recognize a
second procedure in the source code. When
the new Pager. B09 encounters an additional
procedure, it skips to the next page and
changes the header on the page to the name
of the new procedure. The page numbering
remains intact. He also corrected the way the
program handles line numbers. Addition-
ally, it prompts for an output device so you
can use any parallel printer or even / TERM.
Law challenges you to come up with a way
to handle a BASIC09 program line in the form
of:
IF variable=data THEN
variable=null \ ENDIF
Presently, Pager. B09 treats the rest of the
program following this line as if it were still
in the IF loop. In other words, Pager only
recognizes control structure keywords when
they are at the beginning of a line.
And here's another tip. Why not write this
program so that it receives input from
standard input and sends output to standard
output. If you do this, you could use it as
a filter. To make Pager. B09 read from the
standard input path, take out this line and
the conditional code following it:
INPUT "File to list: "filename
To make Pager. B09 send output to the
standard output path, you must make
similar changes. Take out the prompt for the
output device and the code that uses it.
Then, remove the following four lines:
OPEN #path, filename: READ
OPEN #pr inter, output : WRITE
CLOSE #path
CLOSE #printer
Then, early in the program add the follow-
ing two lines:
path:=0(
printer :-l
August 1986 THE RAINBOW 201
After you do this, the program gets input
from the standard input path when it en-
counters the line, "READ ttpath, line".
Likewise, it sends output to the standard
output path when it encounters any line
containing "print ttpr inter".
Run Pager. B09 with OS-9 command lines
like this:
0S9: basic09 Pager
<any_BASIC09_file >/P
0S9: basic09 Pager
<mor e_J3 AS IC0 9_J3our c e >a_spoo 1 er_f il e
0S9; basic09 Pager
<any_B AS I C0 9_S our c e
The first command line sends its output
to the printer. The second line saves the
output in a file on disk which you can later
print, and the last line sends the output to
the Color Computer screen.
While you are typing Pager. B09 into the
CoCo you will find several program lines
longer than the length of the screen. To get
around this problem, type a linefeed char-
acter and continue to type the program line.
Remember, do not press the ENTER or
RETURN key after you press the linefeed key
— just keep typing. To generate a linefeed
character on the Color Computer, hold
down the CLEAR key and press the 'J' key.
BASIC09 will let you enter the long series of
IF ... OR ... OR .. . THEN statements in
Pager. B09 if you do this. This series appears
twice in the listing and both times the three
lines of code in the listing should be entered
as one line of code.
A New line.c
Law also modified the standard line.c
program that comes with the Microware C
compiler from Tandy. The program now
paginates the listings at 66 lines per page and
includes a header that prints the filename
and pager number. He also gives you the
ability to add the string "/*page*/ " to your
own code. When the line.c sees this string it
automatically skips to the top of the next
page. This is a handy feature since it allows
a way to add a simple comment to programs
to keep a routine from being listed on two
pages.
Our final listing this month comes from
Matthew Belmonte of Alexandria, Virginia.
The listing stat.a is written in the RMA
assembler format. RMA is the assembler
called C.Asm in Microware C. It just might
come in handy if you are trying to port C
programs from UNIX over to OS-9. The
short c program, example. c, shows how to
use "stat( )" from within your own c pro-
grams. To link stat( ) with example.c, use the
following command line.
clink /dl/lib/cstart.r
example. r stat.r -#=/dl/
example -l-/dl/lib/clib.l
That's it for August! But, never fear, next
month should be just as much fun as we try
to come up with a way to organize your
disks. Till then, keep on hacking! □
