LETTERS TO THE U/k
Turning in the Eyepatch:
A Pirate Reforms
Editor:
After reading Mr. Falk's column in the
April 1987 issue, and remembering several
other articles and letters addressing the
subject of piracy, I have finally decided that
I am tired of being "the bad apple" in my
CoCo System. Over the past year or so, I
have pirated several programs — nearly 15
percent of my library and accounting for a
third of its value. I am truly sorry I have
done this, and I have erased every pirated
program from my disks. 1 1 took a long time
to decide to do it, but I think it was the best
thing to do.
To those of you who also have pirated
software, it's up to you whether or not to
continue breaking the law. There is no
effective way of stopping piracy, but piracy
is an effective way of stopping the CoCo
Community from the rapid and substantial
growth that has become a trademark of our
favorite micro. People often say (I did) that
the pricing of software is outrageous; it may
be, it may not. The pricing of the IBM PC
is outrageous, but that doesn't mean people
stole them instead of buying them. To the
software vendors that 1 pirated from, I'm
really sorry. That probably doesn't do much
good, though. I will try my best to purchase
more software from your companies.

An Offer You Can't Refuse
Editor:
This letter is being written for two rea-
sons, the first of which is to tell you that I
am no longer a member of the CoCo Com-
munity. I am the owner of an IBM Compat-
ible and I will be subscribing to RAINBOW'S
sister publication, SOFT SECTOR. The
CoCo will be given to my 7-year-old grand-
daughter so that she can become familiar
with computers and their use.
The second reason for writing is that I
have saved almost all of my RAINBOW
magazines which date back to November
1982. I want to get rid of them and don't
want to toss them out in the trash. I would
like to donate my collection to a club or
organization that needs them. I will even
throw in about 1 8 issues of Color Computer
magazine, too.

A Fix Here, a Fix There
Editor:
I have been a proud owner of a CoCo 2
for two years and enjoyed OS-9 Level I. I
recently bought a CoCo 3 and OS-9 Level
II. Level II is unbelievable. However, when
updating my DEF5 files with the new system
calls, I found out that on Page 8-69 of the
OS-9 II reference manual, important infor-
mation is missing: the call number of
FSRllHRam, which should be 1 03F XX. I am
missing the XX and cannot complete my
updates.
In the April I987 issue, I read the letter
from Mike Roush. Looking at the sche-
matic, the two rows with O and G are
hooked to the joysticks. Two capacitors
(CI 5, CI 8) are also hooked to these rows
and, after a time, the capacitors tend to leak
(slowly short to ground). I cured my prob-
lem by changing those capacitors. I propose
to Mike to unsolder those two capacitors
and, if the problem is cured, just replace
them. Page 51 of the CoCo 2 Service Man-
ual, Paragraph 5.3. 1 , "No Keyboard Entry,"
mentions those two capacitors as a potential
cause.
Finally, I want to congratulate your
magazine for having comprehensive and
honest product reviews that uncover not-so-
honest suppliers.

Editor:
I have developed what you might call a
beginner's robot. It is a remote-controlled
tank such as Radio Shack sells, hooked up
to the CoCo, with a minimum of parts. I am
working on ways of marketing this device,
but, meanwhile, plans are available for
enterprising types for $25. If interested,
contact me at 523 W. Spring Street, 22664.

BACK TALK
Editor:
I read with amazement the letter from
John Tiffany in the March I987 issue. John
claims to be "against the abuse of illegal
drugs"but is "shocked and annoyed "at your
using CoCo Cat to spread the word concern-
ing the dangers of drug abuse.
You can't have it both ways. You can't
oppose illegal drug use and at the same time
remain silent on the issue, rainbow has
taken the lead in trying to reach the youth
of our great nation by using our magazine
to inform them that drugs are indeed "not
user-friendly." How can you say that you are
"against the use of abuse of illegal drugs"
and in the same breath take our magazine
to task for saying exactly the same thing?

The Borrowing Attitude
Editor:
No matter how much protection a small
developer may have, the economics of law
make it very difficult for any but the giants
to bring successf ul action against a company
that is stealing software — especially since
most corporate theft occurs when distribu-
tors underreport copies sold on royalty
reports. Who, but the largest can afford
accountants to verify reports? However, the
theft of computer software in this blatant
manner is isolated and protected (as your
article pointed out).
The reason so much computer software is
stolen is an attitude in the general public that
"borrowing" software is OK. I believe this
attitude is fostered by a number of forces in
our society. A few of which come to mind

include schools that purchase one copy of a
piece of software and then make copies for
all their machines. Software developers
themselves must shoulder a part of the
blame. After buying a dozen pieces of
software that are overpriced or just don't
work, it's no wonder people are concerned
about shelling out another $30 for a pig in
a poke.
Currently, the Canadian government is
working on a new copyright law. And
although there is no doubt that it is needed
and overdue, I really greet it with a long
yawn. The fact is that laws are only useful
when the majority of people decide to obey
them. What is needed now is a massive
public education program to change the
attitudes of the general public.

And Still They Complain
Editor:
Why all this hostility toward the CoCo 3?
Tandy gives us a computer that does virtu-
ally everything we ask and people are not
happy. I think the only valid thing to get
upset about is third-party software not
running. Will there be patches? I think so.
What about the couple of Tandy programs
that don't run? I feel Tandy should send a
patch to all of the registered owners of those
programs. n

COCO 3
Editor:
I've been waiting on pins and needles for
Tandy to finally come out with a new CoCo
with enhanced graphics, 80-column text
display and more memory. Now it's here,
and yet I'm still waiting to buy one. Why?
Because at a time when everyone else is
making their computers user-friendly and
easier to operate, the CoCo 3 requires that
we learn the OS-9 operating system and
know how to program.

A Vanishing Act
Editor:
1 jusi received Disk Utility 2. 1 A from my
local Radio Shack. In the January 1987 issue
of rainbow [Page 110], the Spectrum Pro-
jects ad stated that Disk Utility is compatible
with CoCo 3. Mine does not boot. I have
tried to call Mr. Rosen only to find that his
answering machine no longer lakes mes-
sages. I tried to leave him E-Mail on Delphi
only to find he is not listed in the member
directory. I don't know what to do. Tandy
says that they are not responsible for "90
series" software and that I would have to
speak to the company that produced it. I
would appreciate any help you can give me.

I do a lot of work with the database
Profile and the word processor Scripsit. I
would like to know if there is software able
to connect those two programs so I would
be able to write an original letter or form
letter with Scripsit and have names and
addresses from Profile inserted automati-
cally.
If not, can you recommend a database
that can write the original letter or form
letter using uppercase and lowercase letters?

No Double-Sided Access
Editor:
When my new CoCo 3 arrived, I discov-
ered it is not compatible with my two half-
size, double-sided drives with a 1 6K JFD-
CP controller. The CoCo 3 doesn't recognize
double-sided drives or J&M, so all of my
disks formatted as such failed to produce
any working programs. The J&M doesn't
recognize any of the new CoCo's commands.
I'm stuck with using my expensive double-
sided drive system as an RS-DOS single-
sided system with over 90 percent of my
programs inaccessable. I have always liked
J&M and their products, but I have received
no help as to what I can do to make my two
systems compatible. ~. . „ ,

Escaping With CoCo 3
Editor:
How do you set CoCo 3 to send an escape
character? I would like to access my work
database over the phone using Compac, but
I must send an ESCA'A' sequence to identify
my terminal type. (Pressing break while
using Compac sends me back to the menu.)
I could use an IBM 3270-type emulation
package for the CoCo to take advantage of
SPF's full screen edit.

I'd like to congratulate you on a great
magazine! I received HOT CoCo magazine
until its demise in February 1986, and I was
glad to see that the Doctor ASCII column
was picked up by your magazine. This
column has already saved me a painful
repair bill.

Software House Comes Through
Editor:
Once again one of your advertisers has
shown outstanding concern and has gone
the extra distance to satisfy a customer. I
would like to publicly acknowledge The
Software House in Redford, Michigan.
When I had a problem with an order, Dallas
Cox corresponded with me and compen-
sated me far beyond my expectations.

Sacy, Please Come Home
This is our Sixth Anniversary Issue, and it is always a time for
good feelings on everyone's part here and, I hope, in the CoCo
Community. Naturally, we're pleased and proud to be
celebrating our Anniversary again and, as usual, we have a nice
surprise inside — our CoCo Cat calendar.
The calendar is filled with interesting dates in the history of the
CoCo as well as the usual holidays and a few "extra special" days
you probably didn't know about until now. I know everyone will be
interested, for instance, in celebrating National Pig Week in an
appropriate manner.
With all the hullabaloo, I hate to be on a downer, but I am. And,
though I usually do not share "personal" type things in this column,
this one has been bothering me for some time. I know no one can
help, but, somehow, it seems better to share this tale of "man's
inhumanity to man."
My eldest daughter, Wendy, is just back from a
"Semester At Sea," a program through the Universit
of Pittsburgh. Wendy, who works on the magazine
when she is home, is now a senior at the University j
of Wisconsin-Madison. She's 20 years old. }
Wendy approached me about 18 months ago
to take a "Semester At Sea." The program is fully
accredited and includes regular college credit
courses and practicum studies while the students
spend about four months on a ship as it circles the
globe. The spring semester included stops in Spain,
Yugoslavia, Turkey, the Soviet Union, Egypt, India, Malaysia,
Taiwan, China, Hong Kong and Japan. The ship left the Bahamas
and docked a few weeks ago in Seattle.
To balance out costs for the academic year, Wendy stayed home
during the fall semester and attended the University of Louisville.
She also worked part-time — to pay for part of her tuition this spring
and to provide herself with spending money for the trip. I was really
proud that she was so mature in accepting part of the financial
responsibility for the trip. In sum, her junior year in college didn't
cost "Daddy" any more than it would have had she been at
Wisconsin.
And it was a wonderful experience for her. She was exposed to
many different cultures, formed firsthand opinions of countries,
peoples and economic systems, and she learned a great deal, too,
through her practicum classes in addition to more traditional studies
on ship.

Everyone was looking forward to
her return — to hearing the stories,
getting her impressions, looking at
her photographs.
Wendy took 17 rolls of pictures,
almost 550 of them. Friends
snapped her standing in front of a
line of gray-clad Russian soldiers in
Red Square, at the Taj Mahal, be-
side the Golden Horn, on a camel at
the pyramids, at a market in China,
in front of the bullet train in Japan.
And so on.
We don't have a single one of
those pictures.
We don't have the one present
Wendy bought herself — some
pearls she had saved money for so
she could get them in Hong Kong.
We don't have Sacy, either.
Sacy is Wendy's teddy bear. He's
17 years old. The name, inciden-
tally, means "Soft And CuddlY."
Sacy is who Wendy cried with when
she didn't get in the high school ciub
she wanted. He accompanied her on
a scholarship summer to Israel. He
kept her company when she broke
both her arms at the same time.
Sacy has been to Denver and to
Washington, D.C. He's been to
Florida and he's been to Kansas
City. He's lived in Tuscaloosa, Ala-
bama, Chicago and Madison, Wis-
consin.
And he's been almost all the way
around the world.
Someone, you see, stole Wendy's
tote bag from the customs shed of
Pier 28 in Seattle while Wendy went
back onto the ship to get her other
luggage. That tote bag contained
Wendy's pearls, a present for Wend-
y's sister, 17 rolls of film. And Sacy.
Wendy spent four hours searching
the pier for her tote bag. She talked
to longshoremen and ship person-
nel, to the police and customs
agents, to other students and
strangers. No tote bag. No Sacy.
Wendy has written to all 400
students who traveled with her,
asking if anyone might have seen
something. So far, no one has.
Students have volunteered to send
her copies of their pictures — but no
one has many pictures of Wendy, of
course.
And no one has Sacy.
Just last night, Wendy came to
talk to me, so upset I thought she
had broken up with her boyfriend.
"Why did they have to steal Sacy
and my pictures?" she asked.
"Couldn't they have at least sent
Sacy home?" Then: "Do you think
Sacy's OK?"
I told her I was sure Sacy was, but
we both knew it was a lie. Whoever
stole the tote bag knew it belonged
to a youngster — that the film had
to represent irreplaceable memories
and the teddy bear had to be very,
very special. They could have kept
the other stuff and just sent the
pictures back.
And sent Sacy home.
So I'm down even if this is our
Sixth Anniversary Issue. Somehow
it helps to have written about it and
I hope you'll pardon my injecting a
personal issue in this space.
After all, it's the first anniversary
issue when Sacy hasn't been here to
celebrate with us.

Screen Star implements the popular WordStar editing capa-
bilities. Screen Star uses the disk as an extension of memory
so it will edit tiles larger than memory. Move, copy, or delete
blocks of text with one keystroke. Powerful cursor commands
allow fast and easy movement throughout the document. The
find/replace command makes moss changes and searches
a snap. Set Tabs, toggle the video, access the OS-9 Shell and
choose wordwrap. Define up to 10 function keys for fast, repeti-
tive functions. Imbed Computer ware's Text Formatter com-
mands in your Screen Stor file for maximum word processing

file, Smart Speller uses a small dictionary which contains the
most common English misspellings and their correct spellings.

BUILDING JULY'S RAINBOW
A muscular Rainbow with an M-60 . . .
The OS-9 Users Group battles back
And, Rainbow's Color Computer Hall of Fame
If you saw People magazine's special issue on Russia a few weeks ago, perhaps
you read that many videotapes produced here in the West are stolen by
underground "video garage" operations in the USSR and reproduced to run
on Russian video cassette recorders. Among the "hot" videos are the Rambo duo.
Curiously enough, not only is Sylvester Stallone's dialogue dubbed in by a
woman on one popular, but illegal copy (she does the entire sound track), but
the word "Rambo" was mistranslated into "Rainbow"! A soprano soldier named
Rainbow wielding a machine gun! Well, recollection of this came immediately to
mind during my vacation recently as 1 was riding an express train out of Helsinki,
Finland. Destination: Moscow.
We had been warned to use the restrooms early, before the fretfully hot coach
would be sealed for an enroute immigration/customs inspection. Thus, it was
expected when a tall Russian soldier came into the compartment I shared with
my wife and asked to see our documents, which we were careful to have in total
order. It was just by chance that he asked me to open the very suitcase in which
I had a copy of what else, TH E RAINBOW. It immed iately caught hiseye. "Rainbow!"
he said, and, were it anywhere else, I might have blurted, "Oh, are you a reader?"
Instead, I volunteered, "It's a magazine for home computer users." Home users,
indeed, in a country where even the hotels and biggest retail stores still use the
abacus! He thumbed through it, laid it down, picked it up again and muttered
"Rainbow, Raaaainnnnn-bowww" drawing it out as if he might be considering
whether this was the book that inspired the video! Replacing it in my suitcase,
he made a cursory inspection of our compartment and then picked it up a third
time. I was quite ready to give it to him, but thought better of it when, at last,
he dropped it, saluted us and moved on.
Yes, 1 am proud of THE RAINBOW, now entering its seventh year! Was this the
first copy of THE RAINBOW to enter Russia? Well, while we have no subscribers
in the USSR, and while I saw no computer magazines at any newsstands anywhere,
I suspect my copy is not the first. In fact, a while back, I'm told, the Russians
approached Tandy, as they did Apple, about introducing the Color Computer to
the Russian marketplace! Whatever negotiations took place apparently did not
work out, so, alas, the Russian soldier and I still have little common ground.
Bruce Warner hasn't told me if any copies of the OS-9 Users Group's MOTD
newsletter are headed toward the Kremlin, but I do want to report that, after an
eight-month suspension, publication of MOTD has resumed and a fresh copy is
right here on my desk. If you did n't get one, you might write to: OS-9 Users Group,
ATTN: Membership, 1715 East Fowler Avenue, Suite R237, Tampa, FL 33612.
The group has suffered some setbacks over the past year, but appears to be getting
back on track with folks like Bruce, Bill Turner, David Kaleita and Carl Krieder
putting in enormous amounts of volunteer hours toget things moving again. That's
good news for all of us and, while 1 know many of you may be frustrated over
past experience with the group, I urge you to please show patience and
understanding and help these new officers get things rolling again.
Along with my usual invitation for you to join the tens of thousands who
subscribe to THE RAINBOW (the magazine, not the soprano soldier), let me cordially
invite you to nominate someone for induction into Rainbow's Color Computer
Hall of Fame! Yes, you can nominate your favorite CoCo Community citizen and
the selection committee will carefully consider your nomination. The time and site
for the formal induction ceremony are yet to be determined, but now is the time
for nominations. All you do is fill out the nomination form (see Page 104) and
mail it in. No essay nor documentation is required or desired, and just one
nomination per reader please. We'll discuss the Hall of Fame in more detail later
on; in the meantime, keep following THE RAINBOW, the Rambo of computer
magazines.

With the A-BUS you can plug your PC (IBM, Apple,
TRS-80) into a future of exciting new applications in the fields
of control, monitoring, automation, sensing, robotics, etc.
Alpha's modular A-BUS offers a proven method to build your
"custom" system today. Tomorrow, when you are ready to take
another step, you will be able to add more functions. This is ideal for
first time experimenting and teaching.
A-BUS control can be entirely done in simple BASIC or Pascal,
and no knowledge of electronics is required!
An A-BUS system consists of the A-BUS adapter plugged into
your computer and a cable tc connect the Adapter to 1 or 2 A-BUS
cards. The same cable will also fit an A-BUS Motherboard for
expansion up to 25 cards in any combination.
The A-BUS is backed by Alpha's continuing support (our 11th
year, 50000 customers in over 60 countries).
The complete set of A-BUS User's Manuals is available for $10.

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.
CoCo Max disk systam, with Y- cable.
Is CoCo Max for you ?
Anyone who has ever held a pencil or
a crayon for fun, school or business
will love it. A 4 year-old will have fun
doodling, a 1 5 year-old will do class
projects and adults will play with it for
hours before starting useful
applications (illustrations, cards,
artwork, business graphics, flyers,
charts, memos, etc.) This is one of the
rare packages that will be enjoyed by
the whole family.
What made CoCo Max an
instant success?
First there's nothing to learn, no
syntax to worry about. Even a child
who can't read will enjoy CoCo Max.
Its power can be unleashed by simply
pointing and clicking with your
mouse or joystick. With icons and
pull down menus, you control CoCo
Max intuitively; it works the same way
you think.
Don't be misled by this apparent
simplicity. CoCo Max has more power
than you thought possible. Its blinding
speed will astound you.
It lets you work on an area 3.5 times
the size of the window on the screen.
It's so friendly that you will easily
recover from mistakes: The undo
feature lets you revert to your image
prior to the mistake. As usual, it only
takes a single click.
Later, we will tell you about the
"typesetting" capabilities of CoCo
Max II, but first let's glance at a few of
its graphic creation tools:
With the pencil you can draw free
hand lines, then use the eraser to
make corrections or changes. For
straight lines, the convenient rubber-
banding lets you preview your lines
before they are fixed on your picture.
It's fun and accurate. Lines can be of
any width and made of any color or
texture.
The paint brush, with its 32
selectable brush shapes, will adapt to
any job, and make complicated
graphics or calligraphy simple.
For special effects, the spray can is
really fun: 86 standard colors and
textures, all available at a click. It's
like the real thing except the paint
doesn't drip.
CoCo Max will instantly create many
shapes: circles, squares, rectangles
(with or without rounded corners),
ellipses, etc. Shapes can be filled with
any pattern. You can also add
hundreds of custom patterns to the
86 which ars 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.
Pull down menus
Zoom In I
Control Over Your Work
CoCo Max's advanced "tools" let you
take any part of the screen, (text or
picture) and perform many feats:
• You can move it around • Copy
it • Shrink or enlarge it in both
directions • Save it on the electronic
Clipbook • Flip it vertically or
horizontally • Rotate it • Invert
it • Clear it, etc. etc.
All this is done instantly, and you can
always undo it if you don't like the
results.
For detail work, the fat bits (zoom)
feature is great, giving you easy
control over each pixel.
To top it all, CoCo Max II works in
color. Imagine the pictures in this ad
in color. If you own a Radio Shack
CGP-220 or CGP-1 1 5, you can even
print your work in full color !
There is so much more to say, such as
the capability to use CoCo Max
images with your BASIC programs,
the possibility to use CoCo Max's
magic on any standard binary image
file. There are also many advanced
features such as the incredible lasso.
Inside the Hl-Res Input Pack
Why a Hi-Res Input Pack ?
Did you know that the CoCo joystick
input port can only access 4096
positions (64x64)? That's less than
1 0% of the Hi-Res screen, which has
491 52 points! (256x1 92). You lose
90% of the potential. The Hi-Res Input
Pack distinguishes each of the 491 52
distinct joystick or mouse positions.
That's the key to CoCo Max's power.
The pack plugs into the rom slot (like
a rom cartridge). Inside the pack is a
high speed multichannel analog to
digital converter. Your existing
joystick or mouse simply plugs into
the back of the Hi-Res Pack.
Electronic Typesetting...
You'll be impressed with CoCo Max's
capability. Text can be added and
moved around anywhere on the
picture. (You can also rotate, invert
and flip it...) At a click, you can choose
from 1 4 built in fonts each with 1 6
variations. That's over 200 typestyles !
Examples of printouts
Printing Your Creations
There are a dozen ways to print your
work. All are available with a click of
your joystick (or mouse) without
exiting CoCo Max. Your CoCo Max
disk includes drivers for over 30
printers !
All the CoCo Max pictures are unretouched screen shots or printouts (Epson RX-80).

The Rainbow Introductory Guide to
Most people have been using statistics since they learned
to talk. Statistical results and concepts turn up everywhere.
A large part of our daily news consists of statistics. Results
of opinion polls, surveys, research studies, the Dow Jones
industrial average and, of course, our sports news are all
statistics. But statistics are often misused. The informed
person needs to understand the basic concepts in order to
judge the appropriateness of applications.
Rainbow Contributing Editor Dr. Michael Plog and co-
author Dr. Norman Stenzel have written The Rainbow
Introductory Guide to Statistics just for beginners. It is an
easy-to-understand guide to this sometimes mysterious area
o£ mathematics. Their aim is to introduce readers to the
realm of statistical processes and thinking, and they believe
that the Tandy Color Computer is an ideal machine for the
reduction of data.
Sharpen your skills with The Rainbow Introductory
Guide to Statistics for only $6.95. Included in the book is
the CoCo-Stat program, a BASIC statistics program just for
the Color Computer. (80-column printer required.) Forget
the typing hassle by ordering the accompanying Statistics
Tape or Disk for only $5.95. Spend your time learning and
enjoying the new material, not debugging your typing. Just
pop in the tape or disk and you're ready for action!
Save when you buy The Rainbow Introductory Guide to
Statistics book together with the tape or disk. Get both for
only $11.95.

Our
Fourth
Adventure
Contest
Time passes quickly as you use your nimble fingers to escape
the very passion that consumes you. Thoughts are fleeting at
a time in which you need them most. The spidery web of
mystery and intrigue you have spun is now entangling you. Every
breath you take . . . Every move you make ... Is it correct? Will it even
accomplish the task at hand? Is there any time left?
No, we don't mean to imply time is nearly up for our Fourth
Adventure Contest. Plenty of time remains. However the final
deadline for your entry in this contest is August 15, 1987 - a date
that is rapidly approaching. So, you'd better get started soon, if you
haven't already begun.
What? No ideas, you say? Just take a look around you! Your
everyday life presents you with hundreds. Just sit down and start now!
We await the very best you have to offer. If you want some pointers,
check out "The Adventure Writer's Toolkit" (April 1985, Page 105) by
Eric W. Tilenius. Or, for another helping hand, see "The Adventure
Processor"' (August 1986, Page 26) by Bill Cook. These articles, and
many more, are Just what you need to get started on the right track.
Your Adventure can be written for a 4K early model CoCo, or it
can be written to take advantage of all the features in a 512K CoCo
3. It can be written under Disk basic, or it might be a creation in
BASIC09.
Judging: The judges of the Fourth Rainbow Adventure Contest will be looking fa several
things in each entry. In addition to ensuring each submission is complete, they will consider
the following:
• Originality • Vocabulary and Grammar
• Creativity • Responsiveness
• Programming Efficiency « Level of Challenge
• Clarity of Instructions • Enjoyment
• Ease of Use
The judges will also be concerned with the "publishability" of each Adventure. A shorter
program is easier to fit into print (both in THE RAINBOW and any subsequent Adventure
book) as well as being easier for the reader to type in. While the use of graphics tends
to enhance any program, graphics are not necessary for an Adventure to win. The winning
entry will be chosen for its unique appearance. Make your Adventure stand above the
rest!
RULES: Your submission should include all programs and information needed to set up and
run the Adventure. All programs must be sent on tape or disk with several saves of each
program including at least one ASCII save. If an Adventure cannot be loaded, It cannot
be judged. We will not type in even the shortest of programs! Hard copy of all program
listings and instructions must also be included. If your Adventure uses machine language
routines, oil source code, as well as assembled object code, should be included on the
tape or disk. Indicate the minimum CoCo system required to run your Adventure and
include a complete solution!
Please, don't use packed lines that can't be LiSTed or LLISTed for the benefit of our readers.
Your program should run on standard Radio Shack equipment without requiring any
special modifications and should not rely on commercial software for its execution. The
only exception is the use of the OS-9 operating system (level I and Level II) and BASIC09.
If your Adventure uses graphics, make sure the graphics are self-contained. In other words,
don't submit a program that loads several different graphics screens unless those graphics
are aeated by a publishable program included in the submission.
In summary, send a complete package. Put the accompanying article, documentation,
listings, complete instructions and solution, and cover letter on paper. Include your name,
address and telephone number on each page of all materials. Be sure to write-protect
your disk or punch out the tabs on your cassette to avoid accidental erasure, and label
each with the name of the program(s) and your name and address. As In any contest
packaging does make a difference.
Your entry must be postmarked no later than August 15. 1 987, in error-free condition. Each
entrant will receive a free pass to the RAINBOWfest of his or her choice. You may also win
one of the many prizes donated by our generous advertisers as well as have your program
published in THE RAINBOW. So, get a move on! Write it up. put it together and send it
to:
Adventure Contest Editor, Rainbow Magazine, 9509 U.S. Highway 42,
P.O. Box 385, Prospect, KY 40059.
Additional Rules: All entries must be original, unpublished and unmarketed works (no
"conversions"). No programs that have been placed in the public domain are eligible.
All entries become the properly of Ralsoft Inc., publisher of the THE RAINBOW. The decisions
of the judges will be final. Duplicate prizes will be awarded in the event of a tie. Winning
entries will be featured In a future issue of THE RAINBOW.
Prizes: Following is partial list of the prizes the winners of our
Fourth Rainbow Adventure Contest will be receiving. And.
many more prizes are being donated each day!

July 1987 THE RAINBOW 29
The
Perfect
Disk
Manager
By A.L. McGarrity
I suppose my personal search for the
quintessential disk management
utility really began almost the day
I plugged in my first CoCo disk drive.
After storing a few short test files, I
eagerly typed DIR, and filename, exten-
sion, file type, format, and number of
granules appeared. I suppose 1 was
relatively content with DIR at that
moment — until I stored my 15th file.
Whoops! Didn't an entry "roll off" the
top of the screen?
Reading a bit, 1 became acquainted
with (but not very good at) the SHIFT-
@ technique. There had to be a better
way.
Later, having obtained a GE Ter-
miNet 300 to produce hard copy, 1
encountered the first of several referen-
ces to the "device number" poke: POKE
Mr. McGarrity holds a BS in mechan-
ical engineering from the Georgia Insti-
tute of Technology and has been design-
ing teleprocessing applications for
clients of General Electric Information
Services since 1967. He took up micro-
computers as a hobby about two years
ago.
111,254:DIR. I could finally view the
entire directory at one time. Still, by
now I had been through the RS Disk
Manual with a fine-toothed comb and
knew that just about all the information
I could ever want was there on Track
17.
At about this time, Michael Plog's
article and program on a printed direc-
tory appeared in RAINBOW (March
1983, Page 126). The format was partic-
ularly handy, because it printed the
directory entries into columns: When
cut out and folded in half, it made a nice
record to tuck in the jacket with the
disk. 1 quickly added a number of
enhancements (sorted filenames, time
and date, suppression of the printing of
deleted filenames, and the option of
printing the File Allocation Table) and
still use it today.
The next thing that attracted my
attention was Melvin Hefter's article in
the July 1983 rainbow (Page 152),
describing his program to provide a
granule trace for each file. I had just
encountered an incident where DOS
had obviously become a bit confused
and allocated some of the same granules
to several different files. This hasn't
happened again, but Melvin's program
was useful in helping me salvage what
I could from that disk before re-
initializing it. Also, when one of the
many published disk-checking pro-
grams advises you that, say, Track 10,
Sector 6, Granule 20 is bad, it allows
you to immediately see which program
is damaged.
Then Marvin Swan's comprehensive
Handler utility was published in the
November 1984 rainbow (Page 100),
providing interesting composite infor-
mation across all disks. Although I
found the package as a whole a bit time-
consuming for my own regular use, I
was intrigued by the calculation of the
total number of bytes in each file. I
think there are at least two good reasons
for having this information handy.
First, it provides a fairly reliable clue in
comparing two versions (copies) of the
same program to determine whether
they are identical — if the totals agree,
they probably are.
Second, when you see, for example,
that you have accumulated three or four

disk utility programs each containing
400 to 500 bytes (but each taking up
Ves of a disk), it suggests the need to
combine them into a single file for
storage efficiency. In the simplest case,
you can just RUN 1000, RUN 2000 5 etc.
If you want to get a little fancier, you
can add a short "menu" program (at the
lowest range ofline numbers) informing
the user what is available, should he
neglect to type a line number after RUN.
With this rich background of ideas,
I carefully considered what information
1 most wanted in directory reporting for
my expanding disk library (preferably
in an Sl^-by-l 1 format), and the result
is embodied in the programs Diskdata
and Locator,
Diskdata
First, only currently stored files are
listed, and these are sorted alphabeti-
cally (using a fairly fast "pointer"
sorting algorithm). Extension, file type,
and file format are listed, along with the
number of granules, bytes used, and
total bytes lost — that is, the unused
bytes in the last granule. The granules,
bytes used, and bytes lost columns are
totaled, so it will be evident what degree
of storage efficiency you are achieving.
Referring to the column headings, NS
is the number of sectors used in the last
granule ( I to 9), and ODE) is the number
of bytes used in the last sector (0 to 256);
these are not terribly useful, perhaps,
except in verifying the correctness of the
figure shown for total bytes used. You
could, in fact, replace them with other
information (e.g., storage efficiency =
100 x [used] / [used + lost]) — or delete
them altogether and "close up" the
report format. Lastly, the granule trace
is shown for each file. The logic flow is
as follows:
After sizing the string pool, declaring
the dimensioned variables, and defining
the PRINT USING formats and report
header strings (lines 160 to 280), the
program prompts for disk name and the
current date and time (320 to 440). It
then prints the report headings (460 to
560) and reads in the File Allocation
Table from Track 17, Sector 2 (600 to
630),
It next begins reading the (up to) nine
sectors of Track 1 7 containing directory
entries and storing all the d ata for each
file (including calculated values such as
number of granules and total bytes) in
the dimensioned arrays (670 to 1080).
When data for the last file has been
stored away, the program jumps to the
sort routine, which alphabetizes the
filename array, N$ (1120 to 1360).
Finally, the sorted directory entries are
printed (1400 to 1520), footed by the
afo rementioned totals. Note that the
subroutine to slew to top of form (1570
to 1630) has substantial delays built in
for my TermiNet 300, which predates
buffered printers. If you are fortunate
enough to have a modern, buffered
printer, you can probably replace lines
1570 to 1590 with a simple PRINTtt -
2,CHR$(12).
Also note that the program keeps you
informed (via the text screen) as to
exactly what is going on at each phase
of the run — something of a personal
fetish.
The program, of course, requires.
Extended BASIC (since RS-DOS itself
does) and fits easily into 32K. It prob-
ably could be made to run in I6K via
PCLEfiR 1 (or the pokes to achieve
PCLERR 0 — see RAINBOW September
1 983, Page I 12) and, if necessary,
shrinking the DIMs in Line 220 (after all,
it is very unlikely that you will ever get
68 files on one disk anyway!).
Locator
When you bought your second disk,
you undoubtedly stored copies of at
least some of your favorite programs
from old number one either for
convenience, backup or both. As you
continued to expand your disk library,
it became expedient to store more and
more files on more than one disk
some high-use utility programs on every
one, perhaps. After acquiring about a
dozen disks, 1 found I could no longer
remember where a particular file (and/
or its backup copies) could be found.
Thus, the need for a program 1 ike
Locator.
Locator simply reads and accumu-
lates the directory entries (Track I 7) for
each disk in your library and generates
a paged, sorted, cross-referenced listing
of filename/extension versus disk ID.
The disk IDs have arbitrarily been
limited to two-character strings, so that
20 of them will comfortably fit on a line
no more than 80 columns wide. 1 refer
to my disks as 00, 01, 02, etc, but Al,
A2, etc., would work just as well.
The program first prompts for the
current date, which is centered in the
report heading. So, whether you prefer
December 20, 1985, or I 2/20/85, it still
looksneat. ltthenpromptsyouto insert
each disk and enter the two-character
ID associated with it. A null response
(i.e., ENTER only) indicates you have no
more d isks to insert.
Notice that after the first one is read,
cumulative totals for number of disks
and number of (unique) filenames ap-
pears at the bottom of the screen, as well
as a list of IDs of disks already pro-
cessed.
When the last disk has been pro-
cessed, you are asked whether you
would like the filenames sorted. If so,
the same pointer sort used in Diskdata
takes place. Sorting 200 filenames (with
their extensions) takes about 95 sec-
onds. The report is then printed.
As with Diskdata, you may want to
remove some of the printer delays that
my unbuffered TermiNet requires.
With Diskdata and Locator, I fee!
that 1 have finally achieved my own
quintessential disk management utility.
Perhaps it will become yours, too, or
maybe it will merely provide the starting
point in your own search.

The Best
The indispensable
The
THE COLOR COMPUTER MONTHLY MAGAZINE
THE RAINBOW is the biggest, best, brightest and
most comprehensive publication a happy CoCo
ever had! THE RAINBOW features more programs,
more information and more in-depth treatment of
the Tandy Color Computer than any other source.
A monthly issue contains more than 200 pages
and up to two dozen programs, 14 regular columns
and as many as 20 product reviews. And advertise-
ments: THE RAINBOW is known as the medium for
advertisers — which means every month it has a
wealth of information unavailable anywhere else
about new products! Hundreds of programs are
advertised in its pages each month.
Every single issue of THE RAINBOW covers the
wide spectrum of interests in the Tandy Color
Computer — from beginners' tutorials and arcade
games to telecommunications and business and
finance programs. Helpful utilities and do-it-
yourself hardware projects make it easy and fun to
expand your CoCo's capabilities. And, monthly
reviews by independent reader reviewers take the
guesswork out of buying new software and hard-
ware products.
Join the tens of thousands who have found THE
RAINBOW to be an absolute necessity for their
CoCo. With all this going for it, is it surprising that
more than 90 percent of THE RAINBOW subscrib-
ers renew their subscriptions? We're willing to bet
that, a year from now, you'll be doing the same.

REPRODUCTION
EARS Does It All!
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 factyou 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 ot cake ! The single BASIC
line: 10 LISTEN: MATCH will instruct
EARS to listen to you and return the
matching phrase.
It Talks. EARS is alsocapable of high qual-
ity speech. Wemean 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)
B79-6044, 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 lo 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 (he
Radio Shack Plug 'N' Power controller.
For example, you can control your TV by
saying "TV ON" or "TV OFF". . $24.95

By Gary MacLellan
es is tors is a colorful, educational program that can
help leach the color codes that denote different
amounts of resistance. It is self-prompting and easy
to use, which makes it useful for individuals learning
electronics or for electronics classes, as well as for anyone
who needs a handy way to identity the various color codes.
Resistors first prompts for type of monitor, then displays
a set of color bars for a color test. After you make any
necessary adjustments, you have two choices. If you enter
a resistance (e.g., 680 ohms), the program will provide a
graphic display of the corresponding color code (blue/ gray/
brown, in this case).
The other option is to enter the color code. You are
prompted to enter the names of three colors, one at a time.
The program then res ponds with the corresponding
resistance.
Whether you Ye an electronics novice looking for a
learning aid or an experienced electronics enthusiast in need
of a timesaving resource, 1 hope this program makes
identifying resistors easier for you.

July 1987 THE RAINBOW
Achieving
Simple Equ
ii V
By Richard Monroe
Balance is an educational game that I use with 5-
to 7-year-old children who have some type of
learning handicap. It is designed to develop/
reinforce problem-solving skills in relation to simple
equalities, after the concepts of simple addition and
missing addend have been taught.
Our school uses Wynroth Math Programs (Copy-
right 1975 by Lloyd Wynroth, Ph.D., LLB) to teach the
four basic operations and the base 1 0 system. The screen
format is based on one type of problem presentation
from Wynrothfs worksheets. This allows easy transfer
from paper/ pencil task to the use of the computer.
To solve a problem, Balance requires a two-step

has laughl handicapped students for the last 10 years.

education classroom.

approach. First, the child must solve the left side of the
equation by adding two randomly chosen numbers from 0
to 10. The "Scratch Pad" area reproduces this problem in
the lower part of the screen. This sum must be solved
correctly before the second step is encountered. If the sum
is entered correctly, it appears and "floats" over and up to
the left side of the equation. This sum will stop over the
plus sign.
The second step begins with an arrow cue, which points
to the empty box on the right side of the equation. The child
is now required to apply the missing addend concept to
balance the equation. Incorrect responses are not tallied
during the first step, but are tallied during the second step,
accompanied with sound cues and screen messages. On the
third incorrect response, a special sound cue is used to alert
the teacher. When the problem is solved, the sum on the
right side of the equation will appear over the plus sign,
indicating that the equation has indeed been balanced.
After 10 problems, the screen displays the score and a
prompt to continue or end the program. The sounds at the
end of the program were adapted from Raymond Larabie's
One-Liner that appeared in the December 1985 issue of
RAINBOW.
Ideally, the empty box (missing addend) should appear
in different positions on the screen. But since this is my first

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. Those wishing remuneration should so state
when making submissions.
For the benefit of those who wish more detailed
information on making submissions, please send a

EDUCATION NOTES
Spell Down to
Vocabulary Fitness
By Steve Blyn
Rainbow Contributing Editor
This month, we present a language
arts game we have played with
classes for many years. It is use-
ful for helping students become more
familiar with certain key words. These
are usually spelling words, but may be
any kind of vocabulary words.
We call this game Spelldown. It is a
way of practicing spelling and diction-
ary skills. A key word is introduced on
the blackboard or computer. The word
is then written vertically, letter by letter,
down the side. The word is also written
in backward spelling order.
The idea is to make a word that
begins with the first letter and ends with
the last. Next, try to make a word that
starts with the second letter and ends
with the second to last letter. The game
proceeds in this fashion until all of the
letters are used. The student has now
thought of or used the dictionary to
locate as many words as there are letters
in the key word.
Let us suppose that the word "disk"
is typed in as the key word. The com-
Steve Blyn leaches
both exceptional
and gifted children,
holds two master's
degrees and has
won awards for the
design of programs
to aid the handi-
capped. He owns Computer Island and
lives in Staten Island, New York.
J
puter prints the letters D, I, S and K
down the side of the screen. The letters
K, S, I and D form the word spelled
backward. They are also written down
the side of the screen. The screen looks
like this:
D -
- K
I -
- S
S -
- I
K -
- D
The student's task is to figure out
words that begin and end with the
letters on each line. Examples might be
as follows:
DESK
ICICLES
SOME
KEND
After these four words are entered,
the computer has you evaluate each.
Since the words "desk," "icicles" and
"kend" begin and end with the correct
letters, you will merely be asked
whether or not they are correct — real
words spelled correctly. The child's
honesty is assumed here.
A dictionary would have to be in-
serted into this program if we wanted
the computer to check the spelling of the
many words that are possible. We would
hope, instead, that the child uses a real
dictionary to check the spelling. A
teacher, parent or a buddy may also be
used to check the correctness of these
words.
At this point, the student should get
credit for the words "desk" and "ici-
cles." Since "kend" is not a real word,
no credit is given for it.
Words that do not start or end with
the proper letters are flagged by the
computer. A message appears to tell the
student where the mistake is. In our
example, the word "some" is incorrect
because even though it is a real word,
it does not end with the required letter
I.
After all of the words are evaluated,
the score for this round is shown. In our
sample, the child receives a score of 50
percent. The student may then either
press the letter E to end the program or
A to go again.
Here is how the main program ele-
ments operate. Lines 50 to 80 ask the
child to put in a key word. The program
rejects words that are longer than 10
letters. The reason for this is that the
screen would not accommodate longer
words neatly. The new CoCo 3 has a
larger screen that overcomes such prob-
lems.
Lines 90 to 190 print the first and the
last letters of the word up and down
near the right side of the screen. Lines
210 to 240 allow the child to put in the
created words. Lines 260 to 360 evaluate
these words. Correct words are stored
56 THE RAINBOW July 1987
by the variable R, so Line 380 can then
print out the final score at the end of
each session.
We have played this game in classes
with several computers. The children
were divided into teams. Each team
types in the same key word. The team
having the most complete list of words
was judged the winner. We have also
tried to encourage greater thought by
sometimes assigning greater point
values for longer words. We have en-
couraged the use of real dictionaries by
the students during the game. Our
feeling is that it is important to encour-
age students' use of reference materials
whenever possible.
As always, we at Computer Island
hope that your children or students
both enjoy and learn from our pro-
grams. □

Every morning and evening, I travel across
Rigaud Mountain to reach the school where I
work. One day, I was intrigued by small tracks
left in the snow; tracks that bore no resemblance
to the ones already familiar to me and whose sight usually
delighted me: deers being pursued by coyotes, hares looking
for food and partridges walking to their hide-outs. I was

that, but 1 soon forgot about them.
One rainy day last summer, I noticed the same peculiar
tracks glistening on a big rock by the side of the road. My
curiosity was piqued. The following weekend, I decided to
make an expedition to examine those strange tracks that
sometimes looked like very small human footprints.
What I couldn't have known was where this expedition
would lead me — right into a fairy world! This world is now
for you to discover. Can you get to the wonderful, tiny
human being I discovered with luck and magic? The only
thing I can tell you is that his domain is well-protected
against intruders. Good luck! You're going to need it.
Le Lutin (The Elf) is a beginners graphics Adventure. It
doesn't have a save feature, but it offers an interesting
challenge in the fascinating world of imagination. Like most
Adventures, Le Lutin requires two-word commands.

HARD DRIVE SYSTEMS for the COLOR C
<h in
m m aoaac apnm JpE Jjf
Several months ago OWL-WARE introduced the Finest OS9 Hard Drive System for the Color Computer,
Now 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 f all flies 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.

POINTERS
In conjunction with the rainbow's Scoreboard, we offer this column of
pointers for our game-playing readers' benefit. If you have some
interesting hints, tips or responses to questions, or want help yourself, we
encourage you to write to the Scoreboard, c/o the rainbow.
FEEDBACK
In response to letters from:
• Marshall Miller: The cover must be
examined and then opened by using the
scepter in Sands of Egypt,
• Noel Nelson and Matthew Lohse: In
Dallas Quest, the parrot knows how to
get past the anaconda. Try EXAMINING
him. To get through the wheat field, you
first must calm the cows in the pasture
by playing the bugle for them and then
you must dig. Read the message written
on the stone and it will tell you the
directions to get through the wheat field.
In Raaka-Tu, where do you find the
jeweled lever, the candle and the lamp
that are used to get past the gargoyle?
Philip Manwarren
Harrington, ME
• John Austin: On Zork I, you have to
read the book after you light the candles
and ring the bell.
• Chad Johnson: When you meet up
with the ghosts in Wishbringer^ there is
nothing you can do to keep them from
taking your items. When you hear the
boots coming, go in a different direction.
There is a token in the fountain that is
guarded by piranhas. To get the token,
you need a worm.
In the Interbank Incident , what do you
do with the book, vase of roses, rope,
dice, perfume, pass, quarter and the old
newspaper?
John Haupt
Salem, OH
• Ian Renauld: In Vortex Factor, to
open the safe you must travel back to get
the document from the desk; it has the
combination on it.
• Emilie Bruchon: In Black Sanctum,
have you tried going upstairs? Type GO
DOOR and GO MIRROR,
In the Interbank Incident, how do I get
on the train to get to Paris? In Ghostown,
where is the bag of gold and how do you
blow up the safe?
Dianne Piper
Belait, WI
• Normand Schafer: To get past the
serpent in Pyramid, GET the statue box,
then GO EAST to the room with the bird
statue and get the statue. Go to the
serpent and THROW the bird.
Andrew Irwin
Port Haron, MI
Half a Chance
Scoreboard:
Some hints for Sands of Egypt: You
need the oil from the snake to get the
scepter. With the scepter you can unplug
the drain and go underground. Be sure
you save the game right when you are
underground because you only have a 50
percent chance of making the right move.

The Values of the Hi-Res
Joystick Interface
By Marty Goodman
Rainbow Contributing Editor
How can I read the values of the
Tandy Hi-Res Joystick interface? How
does this device work?
Gill Winograd
(DEMONN)
Glen Ellyn, IL
The Interface cannot be read without
special machine language subroutines.
Steve Bjork presented such asubroutine
in his Mouse articles in the July and
August 1986 issues. A glance at that
source code will assist programmers
who want to write their own drivers for
this device. OS-9 Level II has drivers for
the Hi-Res Interface, too, so program
development can be done to support it.
The Interface consists of a quad op
amp and an RC ramp generator circuit.
Using a trigger signal from the cassette
output line, it starts the ramp generator,
and then timing loops in assembly
language software are used to measure
the exact amount of time it takes for the

voltage in the RC circuit to rise to the
level of the wiper of the pots in the
joystick. By measuring this time very
precisely, the joystick position can be
read to 10 times the precision measured
with the ordinary (6-bit DAC) joystick
port.
The price for such great resolution is
that it takes more time to read the thing,
and the readings may jitter just a little.
But the port stiil can be read at 30 times
per second in an application like Color
Max 3, which is fast enough to produce
the feel of smooth response. Only pro-
grams written specifically for the Hi-
Res Joystick Interface can use it.
Try to Remember
I'd like to know how to keep a BASIC
program in memory while I format a
disk.
Vince C a sin gal
(DESH)
Miami, FL
The DSKINI (format) command in
BASIC wipes out any program residing
in the ordinary part of the computer's
memory, for it uses that area to build
the image of the track it writes to disk
in the course of formatting that disk.
There is no simple way around this.
You'd have to write your own disk
format code in assembly language and
place it elsewhere in memory (and hope
that your BASIC program is not so big
as to conflict with that special format-
ter) in order to format a disk and still
have a BASIC program left in memory.
I actually did that with my MS-DOS
formatter program published in the
July 1986 issue. I suggest you just
remember to format a bunch of disks
before starting any programming ses-
sion.
Drive Power
How much po wer do I need to supply
to a disk drive system that has four Sc-
inch drives?
James A . Nyman
(NY MAN)
Seattle, WA
These drives use 300 milliamps on the
5-volt line and a maximum of 600
milliamps on the 12-volt motor line. But
that maximum current figure on the 12-
volt line is for both motors going; the
spindle motor spinning and the head
stepper motor madly stepping the head
back and forth. On the CoCo, while all
drive spindle motors are turned on
when any drive is accessed, only one
head at a time is stepped! The figures
cited are rule of thumb figures, and the
figures for any given specific model of
drive may vary by as much as plus or
minus 50 percent. Qume drives are
noted by several owners to be power
hogs, requiring more power than most
others.
For your four-drive system, I'd say
allow for 1 .2 amps on the 5-volt line and
78 THE RAINBOW July 1987
2.0 amps on the 12-volt line, if the power
is being supplied by a single source for
all drives. Many disk drive power sup-
plies use a separate monolithic linear
voltage regulator for each drive's vol-
tage supply. Of course, it is critical that
you properly mount (for heat dissipa-
tion) those regulators on a well venti-
lated heat sink.
I recommend using your multitester
to measure the actual current consump-
tion of your brand of drive. Measure it
on the 12-volt line first with just the
spindle motor spinning, then write a
BASIC two-1 ine program to step the head
madly back and forth. Run that pro-
gram, then measure the current con-
sumption again. This should give you a
good idea of how power hungry your
particular drives are.
Hosting a Hard Drive
I own a CoCo 3, an upgraded Multi-
Pa k. an RS-232 pack, Speech/ Sound
pack, disk drive system and printer. I
just acquired a 20 -megabyte Seagate
SJ225 hard drive and want to hook this
to my system under OS -9. I cannot
obtain the Tandy host adapter for the
hard drive system. Can you suggest an
approach for this?
Mike Perron
(MIKE PA )
Sudbury, Ontario
Hard drive systems require a "host
adapter" that plugs into the CoCo
system bus. Some hard drive systems
(those made by Disto/CRC and by
J&M) have the hard drive host adapter
port on the floppy disk controller card,
but for those, you'd have to buy their
particular brand of disk controller.
In general, hard drive systems on the
CoCo consist of the host adapter, which
is a simple dedicated kind of parallel
port (SASI or SCSI standard) that
connects (usually through a 50-pin
ribbon cable) to a hard disk drive
controller board. The hard drive con-
troller board is a smart device, with
CPUs and memory and all sorts of good
stuff. In turn ? this hard drive controller
board hooks to the bare hard drive,
such as the Seagate you have. Different
host adapters are designed to work with
differing brands of hard drive controller
boards. For example, the Tandy host
adapter requires the Western Digital
WD lOlOtypecontroller board. Where-
as the L&R Tech (sold by Owlware) and
the Disto host adapters are designed to
work with the XEBEC 1410A hard
drive controller board.
Owlware offers what may be an at-
tractive deal: For around $1 10 they sell
you their host adapter, OS-9 driver
software, and instructions on how to
hook in a hard drive controller and hard
drives. You then can "do it yourself" in
terms of obtaining the hard drive con-
troller board and drive.
Clean Up Your Act

There are machine language pro-

Jostle Prevention
/ have recently blown out the 6809 in
both my old CoCo 2 and my new Co Co
3. This has happened when the Multi-
Pak got jostled and partly unplugged
while the power was on. Can you sug-
gest a way of preventing this?
Rick Bet t is
Oakland, CA
1 suggest you obtain a piece of 1-inch
thick plywood, the size of the area
covered by both the CoCo and the
Multi-Pak. Open up both the CoCo and
the Multi-Pak, and attach both cases to
the plywood using wood screws or
counter-sunk bolts. This should make
jostling less likely to result in the CoCo
and Multi-Pak being separated. I might
add that I recommend putting this unit
at some distance from your main work
area using a remote keyboard cable, to
further lessen the likelihood of the
system being jostled.
Missing Analog Input
/ purchased a Magnavox 8 CM 562 a
while ago for my CoCo 2. At that time
I was told it had an analog RGB input.
And so I reasoned it would work with
the CoCo 3. When I got my CoCo 3, I
was unable to find the analog input on
the 8 CM 562. Can you help?
Jim Stewart
(WHEEL/1 MMER)
Fort Wayne, IN
The Magnavox 8CM562 lacks an
analog RGB input and so cannot be
used in RGB mode with the CoCo 3.
The two Magnavox monitors that will
work with the CoCo 3 and give a nice
80-column display are the 8CM515 and
8CM643. The 8CM505 does possess an
analog input, but its resolution is too
poor to support readable 80-column
80 THE RAINBOW July 1987
display. 1 recommend you write to the
dealer who sold you the thing under
such false pretenses and to North Amer-
ican Phillips, the maker of the monitor.
Perhaps one of those can give you some
satisfaction on this unfortunate incident
of apparent product misrepresentation.
"NEC DRAM chips
are generally felt to be
the best for upgrading
current CoCo 3s. "
A Hot512K
The chips on my PBJ '512 K board run
disturbingly hot. Will this be a problem?
Bill Jackson
(B1LUACKSON)
Sacramento, CA
Because of a flaw in the GIME chip,
the timing for the DRAM chips used on
the 512K upgrade boards is a bit off,
and this results in both the chips run-
ning hotter than one might like and in
some particular brands and speeds of
chips doing better than others. NEC
DRAM chips are generally felt to be the
best for upgradingcurrent CoCo 3s. 120
ns are usually preferred, although one
recent rumor has it that the 150 ns chips
may do as well or better. As long as you
can put your finger on the chip and hold
it there without suffering pain or a real
burn, things should be OK. Hopefully,
in the future, a fix for this problem will
be available.
ROM Switching
/ own a Radio Shack controller and
want to switch between two different
DOS ROMs. How can 1 do this?
Mike Tolbert
(M1KEGT)
Greenville, SC
SpectroSystems currently is market-
ing a clever device that allows you to use
either a 28-pin 2764 (8K-by-8) or a 28-
pin 27128 (16K by 8) with the Radio
Shack disk controller. This 24-pin to 28-
pin adapter allows for several tricks.
Apart from allowing the use of the
inexpensive and common 2764-type
EPROMs in the Radio Shack con-
troller, it also allows you to prepare a
27128 with one DOS in the lower 8K
and another in the upper 8K, and to
switch between the two by switching the
state of the A 1 3 address line on the chip
between ground and +5 volts. The
device comes with instructions for use,
although some sophistication and pos-
session of or access to an EPROM
programmer is required. When used as
an adapter for a 2764, no soldering (but
some pin bending) is required. When
used as an adapter for a 27128, solder-
ing of one or two connections will be
required. The really clever thing about
this adapter is that it permits the
adapted EPROM to actually fit inside
the tight space inside the controller.
Look for the SpectroSystems ad in
RAINBOW.
Avatex Difference
What is the difference between the
Avatex 1200 and the Avatex 1200 HC
modems?
Jay Browning
(ZARATHUSTRA)
Savannah, GA
The "HC" in "Avatex 1200HC"
stands for "Hayes-Compatible." The
old Avatex 1200 was apparently rushed
to market with emulation of only a very
minimal subset of the Hayes com-
mands. The 1200HC is fully Hayes-
compatible. The Avatex 1200 is ade-
quate for use with most CoCo terminal
software, but may give problems if you
want to use it with sophisticated auto-
mated software written for IBM PCs
and clones. Also, full and proper Hayes
compatibility is often required for use
with CoCo Bulletin Board host systems.
Overall, I recommend spending the few
extra dollars to get full Hayes compat-
ibility. Your modem will then be far
more flexible and usable with other
systems.
Disto Compatibility
How can I make my Disto Controller
work properly with my CoCo 3?
Denis Giguere
(GIGVEREDENIS)
Shawinigan-Sud, Quebec
To the best of my knowledge, the
Disto Controller is completely
hardware-compatible with the CoCo 3.
If there are problems, they probably
stem from use of some DOS ROM
other than an unmodified Radio Shack
Disk Extended BASIC ROM. Most
current alternate DOS ROMs (ADOS,
CDOS, JDOS, SpectrumDOS, EDOS
and others) will not work properly with
the CoCo 3. Art Flexser will soon be
releasing ADOS-3, a totally re-done
version of his ADOS that will work with
the CoCo 3. The Disto controller pres-
ents the problem of not supporting a
legitimate Radio Shack ROM because
all of its ROM slots are 28-pin. Most
Disto owners who also own EPROM
programmers will burn a 2764 with the
data from a legitimate Disk BASIC
ROM and use it to make their Disto
Controller compatible with the CoCo 3.
DRAM Trouble on CoCo 2s
I've heard of some DRAM problems
with the Co Co 2 that sells for $99. What
can you tell me about this? Is it true that
blown 68B09s are the most common
cause of dead CoCo 3s?
Dennis McMillan
Pittsburg, CA
It is true that some of the suffix
CoCo 2s being sold appear to have an
odd sort of DRAM problem. Specifi-
cally, these are the CoCo 2s that had
provisions on the main board for up-
grade to 64K in any one of three ways:
via two 4464 chips, by a satellite board
that had eight 64K-by-l chips, or by
soldering eight 64K-by-l chips directly
to the motherboard. It seems the units
that have the problems are those made
to have 64K by using eight 64K-by-l
chips, either soldered directly to the
motherboard or on a satellite adapter.
Such computers fail to work with some
educational software ROM packs sold
by Tandy. Most of these problem units
had Hitachi brand 64K-by-l DRAM
chips. The fix for this consists of re-
moving the eight 64K-by-l DRAM
chips and then doing the upgrade using
two 4464 chips inserted into the two 18-
pin DRAM chip sockets.
A dead 68B09 is commonly found as
the cause of a dead CoCo 3. In most
cases, the 68B09 is zapped due to abuse
by the owner of the CoCo 3. It is a great
pity Tandy did not elect to socket that
vulnerable chip. On my own unit, which
I subject to hideous risks in occasional
hacking experiments, I de-soldered and
socketted that chip, knowing that
sooner or later I will want to be able to
quickly and cleanly replace it. I recom-
mend also socketting the 74LS245 data
line buffer chip (IC 3) and the 74LS04
inverter/ buffer on the RGB sync lines
(IC 15) because both of these chips also
have pins that connect directly to the
outside world.

The CoCo
Writes a Program
By Dennis H. Weide
Have you ever wanted to use a
machine language program in a
BASIC program you've written?
ML programs of ten offer f unctions only
available on more expensive machines.
You can write the BASIC program to
load the ML program from tape or disk,
but that can create more problems than
it solves. The answer, of course, is to
convert the ML program to BASIC DPTfl
statements, write the FOR-NEXT loop
and then append the resulting BASIC
programto your program. BASIC Data
Writer can accomplish this function for
you in a matter of seconds.
BASIC Data Writer was written in
PASCAL and compiled into a machine
language program. It writes a complete
BASIC program using REM, DATA, CLS,
CLEAR, POKE, EXEC and FOR-NEXT
statements and saves it to disk, cassette,
screen or printer in ASCII format. The
program can then be reloaded and run
like any other BASIC program.
Dennis Weide is a communications
technician for A T&T communications
in Albuquerque, New Mexico, where he
programs A T&T and IBM PCs. He
enjoys making toys and teaching com-
puter programming.
ASCII stands for American Standard
Code for Information Interchange and
is an alphanumeric character (non-
binary) code that can be read by most
computers. It is often used to transfer
BASIC programs files from one comput-
er to another. BASIC programs are
usually stored in a tokenized format to
reduce access time and the amount of
cassette or disk space required to save
them. But the CoCo can load-and save
BASIC programs in ASCII format. Since
word processors read and write ASCII
files, BASIC programs for the CoCo can
be written on a word processor such as
VIP Writer and saved to disk or
cassette. After saving the program and
exiting the word processor, the BASIC
program can be reloaded and run in the
normal manner. If you've used a word
processor, you can see the advantage of
using its global text editor when creat-
ing BASIC programs.
BASIC Data Writer takes advantage
of that ability to create a BASIC program
from a machine language program
stored in memory. The listing shows the
PASCAL source code for the program. If
you have Deft or another version of
PASCAL, you can key in the source code
and compile it. Otherwise, you can get

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 vou'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 fsn. 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 ♦/ (he best programs for the Color
Computer f have seen...
— Color Computer News, Jan. 1982
TIPI |?U/DITI?I> fLA
But now we've added more power to
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
— I6K, 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 ihe screen at one
time. Compare this with cumbersome
"windows' 1 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:
Printing and formatting: Irives any printer
(LPVtl/VJIf, »MP-l00/2#0, Epson, Okidaia,
Centronics, NEC, C. Itoh, Smith-Corona,
Term in el, etc).

the machine language version from
RAINBOW ON TAPE.
Using the Program
To use the program, first load the
machine language program to be con-
verted according to the instructions
provided with it. You*ll need to know
the decimal addresses of the program.
These are usually included in the in-
structions or articles that accompany
the program. If not, here's how to find
them. For a program loaded from
cassette, usethe followingcommands to
determine these addresses:
Start: PRINT PEEI<(487)*256
+PEEI<(488)
End: PRINT PEEI<(126)*256
+PEEK(127)-1
Exec: PRINT PEEI<( 157)*2S6
+PEEI<(158)
For programs loaded from disk, only
the start and execute addresses are
saved in RAM when loading. It is eas le r
to use one of the many disk utilities
available to print these addresses. How-
ever, if you don't have a disk utility to
do this, find the start and execute
addresses by using these commands:
Start: PRINT PtEI<( 3288 ) *256
+PEEI<(3289)
Exec: PRINT PEEK ( 157) *256
+PEEK(158)
You'll have to make an educated
guess to determine the end address.
Usually, but not always, data state-
ments containing zeroes for the last
severaj data elements indicate blank
memory after the ML program. The
resulting BASIC program will have the
start, end and execute addresses listed
as remarks in the BASIC program.
Once the ML program has been
loaded and the addresses determined,
load BASIC Data Writer. The ad-
dresses of BASIC Data Writer are:
Start: Decimal 25000
End: Decimal 30698
Exec: Decimal 25000
If any part of the ML program falls
inside the range of addresses of BASIC
Data Writer , use the start address offset
option with the CLOflDM or LOflDM com-
mand (see the computer manual for a
complete description of these com-
mands). Use a positive offset to load
BASIC Data Writer at a higher address
or a negative offset to load it at a lower
address. Deft PASCAL generates
position-independent code so the pro-
gram will load anywhere in RAM in-
cluding the upper 32K.
Once loaded, execute BASIC Data
Writer and answer the prompts. Enter
the filename followed by the device
number you want to save the BASIC
program to. Here's a list of the device
numbers used by Deft PASCAL:
:-3 Screen
:-2 Printer

WRITING BRSIC PROGRAM message
appears on the screen, BASIC Data
Writer is writing your BASIC program.
When the YOUR BRSIC PROGRAM IS
FINISHED message appears on the
screen, you can load it back into the
computer and run it or append other
programs to it. It is a good idea to resave
it again in the standard tokenized
format so that it will load faster the next
time you want to use it.
Testing the Program
To test the program, first CLEAR
200,25000 to protect memory. Then
load and execute it. Follow the
prompts, as explained earlier. When
prompted for the addresses, give it its
own addresses. When the BASIC pro-
gram has been written to the device
specified, turn the computer off, wait a
few seconds and turn it back on. Since
this is a long ML program (5,698 bytes),
first PCLEAR1 then load the BASIC
program back in and run it. You should
get BASIC Data Writer back.
This program can be used to create
BASIC programs from any binary file
including music and graphics.
Notes on Using the Program
I) Always use CLEAR 200, 25000
before loading and running Data
Writer.
2) Be careful with start addresses. If
you transfer a graphics file, the
resultant BASIC program will issue a
CLEAR 200, 35B4. This gives BASIC
a high address of 3584 bytes. You will
want to delete this from the BASIC
listing.
3) Be patient when running the result-
ant BASIC listing. Poking all those
values in takes time!

ments, you can address them to me at

" I cannot imagine the CoCo 3 without ADOS-3;
it would not be a complete machine."
The RAINBOW, July 1987
You've moved up lo a CoCo 3 . A powerful new machine. Now, it's time to give BASIC a shot i n the arm, with ADOS-3.
Wouldn't it be nice to turn on your machine and be greeted by an 80-column display, in the colors of your choice,
with your own custom startup message? To run routinely at 2 MHz (double speed) without having to slow down for
disk and printer operations? This and much, much more is possible with ADOS-3, our CoCo 3 adaptation of the
acclaimed original ADOS, which shares the original's virtual 100% compatibility with commercial software. After
customizing ADOS-3 using the provided configuring utility, you can have it burned into an EPROM that plugs into
the Disk BASIC ROM socket, or just use it in RAM as a disk utility. (EPROM + burning will cost $15-20; we provide
information concerning how you can have this done.) Supports double-sided drives (35, 40, or 80 tracks). FAST and
SLOW commands, auto line number prompts, RUNM command, keystroke macros, arrow-key scroll through BASIC
programs, auto-edit of error line, and many more valuable features.

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

88 THE RAINBOW July 1987
Cache of the
By Tony DiStefano
Rainbow Contributing Editor
I recently asked some people who
own computers, "What would you
like to add to your computer?"
Almost 80 percent of them said they
wanted more memory. This is a univer-
sal problem. It is not limited to just the
CoCo. The Apple, Commodore, Atari
and IBM PC owners all said that thay
wanted more memory, too. They want
it in whateverformthey can get it: Main
memory, bank-switched memory,
RAM disk memory, ROM disk mem-
ory, ported memory — whatever the
format, they want more! Well, the CoCo
3 has up to 512K of memory bank-
switched into 8K blocks, we all know
that. RAM disk adapters are available
from several sources, including Disto
(me). ROM disks are not that popular
because they require an EPROM pro-
grammer and a knowledge of machine
language programming.
What is left is ported memory. Now
some people may say there is no differ-
ence between a RAM disk memory and
ported memory. And as far as the
hardware goes, there isn't. The differ-
ence is all in the software. A RAM disk
and related software emulate a disk
drive. You read and write to the RAM
disk via files. To save data, you have to
open a file, output to it, then close the

bec.
it
file. When you want to retrieve data you
have to open the file again, read your
data and close it up when you are
finished. This processtakes time. It also
uses the DOS (Disk Operating System).
Now, ported RAM is the same, but
since it doesn't use the DOS, it is not
restricted to using DOS and files.
You have to configure the use of the
ported RAM yourself. The ported
RAM you will see today is only 2K long.
That means you will have 2,048 bytes to
work with. Now, these bytes are only
eight bits wide. The CPU in the CoCo
can only handle eight bits at a time. So,
when you want to save a numerical
value, it can only be a number from 0
to 255. If you want to use numbers that
aregreater, you must use more than that
one byte. For instance, if you want to
use a number f rom 0 to 65,535, you will
need two bytes. Or, if you want to use
a signed number (i.e., a number from
-32,767 to 32,767) you still need two
bytes.
If you need still bigger numbers, you
will have to go to a different type of
format. A floating-point number takes
up five bytes of memory f or its mantissa
and exponent. An explanation of these
numbers goes beyond the scope of this
article; see a math book for more de-
tails. You can also store alphanumeric
characters. You need one byte for every
character you have to store.
Now let's talk about memory-
mapping. What, more memory-
mapping? I am starting to sound like a
broken record, but I still get a lot of
letters about this subject. So, here we go
again.
The CPU that is used in the CoCo is
an MC6809E. This CPU can directly
access only 64K of memory. In order to
access that much memory, the CPU has
16 address lines. If you count in binary
numbers, 16 lines gives you 65,535
different locations, better known as64K
memory. There are ways of fooling the
CPU into accessing more memory. The
technique is called page- or bank-
switching. Bank-switching means you
have more memory than the CPU can
use at one time, but the memory is
switched back and forth. An example is
the CoCo 3. It comes standard with
128K memory and is upgradable to
512K memory. How is this done?
There is a chip in the CoCo 3 called
the GIME. One of the functions of the
GIME is called an MMU or Memory
Management Unit. The MMU part of
the GIME has the job of accessing 512K
of memory and, at the request of the
CPU, accesses all of it a bit at a time.
A good illustration of this is a radio.
A radio can receive many stations, but
only one at a time. The CoCo 3 has the
equivalent of eight radios. Each radio
can tune in one station at a time. Each
radio (at the choice of the CPU) can
access the same station. In the CoCo 3,
each radio or page is 8K or 8192 bytes.
There are 64 of these pages in a 512K
CoCo 3 (8K x 64 = 512K). These eight
pages of 8K bytes represent 64K to the
CPU. There are eight control bytes in
the MMU for pages. Each byte tells the
MMU which page the CPU wants to
see. Changing the data in these bytes
changes which page the CPU can ac-
cess. That is how the CPU can access
more than 64K memory.

is a mini-version of the MMU. Very
mini. For users of the CoCo 3 with 5 12K
of memory, this may not excite you, but
for the memory-poor CoCo 1 or 2 user,
a few extra bytes are always handy. The
amount of extra memory is only 2K
bytes. Not much by today's standards,
but if you are working on that "does
everything" program and you need "just
a few more bytes" for something, this is
where you are going to find them. I say
mini because the "pages" are only 256
bytes long. With some special circuitry,
that means this only uses up one byte
of memory in the memory map. You
also need one control or address byte.
That is a total of two bytes in the
memory map. Not too bad for 2K of
memory. There is, however, a catch.
There are two ways of memory-
mapping this extra memory. The first is
to have a couple of latches that hold the
address of the memory. You set up the
address of the memory byte you want,
and then you read from, or write to, that
address. That is the fastest way to get
to any one byte, but you need to change
the address every time you want another
byte. The second way is to "auto-
increment" every time you access data.
For example, you read one byte, then
when you read that same location again,
you get Data Address 2; when you read
it again, you get Address 3 and so on,
until you get to the end of your memory.
This is faster than setting up the address
every time you need more data, but
slower when the data you need is at the
end of the file. If you are familiar with
the structure of BASIC files, the first is

like a Random Access File and the
second is like a Sequential File. Both
have advantages and disadvantages.
What I have in mind is the best of
both worlds. A little bit of auto-
incrementing and a bit of address-
latching. This way, you auto-increment
by pages. I think a good auto-increment
value is 256 bytes. That just happens to
bethesize of adisk sector. In a 2K RAM
chip, there are eight 256-byte sectors,
which means you can have up to eight
pages of 256 bytes each. This is the basic
description of the hardware project I
have in mind for today. It is divided into
three parts. The first is the hardware,
the second is the memory-mapping of
the hardware and the third is the soft-
ware.
First, the hardware. In Figure 1, you
will find the schematic diagram of the
Memory Cache Project. The heart of
the project is an HM61 16 memory chip.
This is a 2K-by-8-byte RAM (Random
Access Memory) CMOS memory chip.
It is made by virtually every memory
manufacturing company. The 6116
number will always be the same, but the
letters (which tell you which company
the part comes from) may change.
Attached to the lower eight address
lines is a binary counter. That is the
auto-incrementing part. Attached to the
upper address lines is a latch. That is the
direct access part of the circuit. The
fourth and fifth chips in the group are
decoder chips, which map the thing
properly.
The standard "project-building"
tools are necessary, but there is one
thing to remember. The memory chip I
used is a CMOS part. It is easily de-
stroyed by static electricity, so use a
static-free work place. Also use sockets
when trying out this circuit. It is better
than soldering the chips directly — if
you happen to burn one out, you won't
have to desolder and resolder. All of
these chips are available f rom your local
electronics shop or from CRC Inc. The
project board (to build your circuit on)
can also be obtained from CRC Inc.
The second part of this project is
memory-mapping. The circuit in Figure
1 is mapped at SFF40 (65344). That, as
you know by now, is where the disk
drive and controller are mapped. If you
have a multipack interface, it is not too
bad; you can switch the multipack to the
different slot and work with the extra
memory from there.
If you only have a 'Y' cable, then the
circuit in Figure 1 won't work. You need
the second part. Figure 2 contains a
circuit that decodes the address bus of
THE RAINBOW July 1987
the CPU and maps it into a different
place, ft re-maps the address of SFF40
(65344) to SFF74 (65396), leaving
SFF40 free for the disk drive. This area
of the memory map may be used by
other products, so watch out for mem-
ory conflicts.
Finally, the software. It is not hard to
access this memory cache. It is in two
parts. The first part is to set up which
of the eight pages you want to use. You
do this by storing the page value at the
base location. An example of this in
BASIC is POKE X , A y where X is the base
address. The base address is SFF40
(65344) if you are using just the circuit
in Figure I and SFF74 (65396) if you are
also using the circuit in Figure 2. The
value A is the page number you want
to access.
The second part is reading data or
writing data into the 256-byte block.
Remember, it is auto-incrementing and
you have to access it 256 times to get to
the last byte. An example of writing to
the page in BASIC is:
1000 FDR /= 1 TO 256
1010 POKE Y , A{l)
1020 NEXT /
where / is your 256 auto-increment
value. Y is your base address + I and
A[l) is an array of data 256 bytes long,
which must be previously defined. To
read the block in BASIC, use this exam-
ple:
2000 FOR / = 1 TO 25S
2010 A{1) = PEEK ( Y)
2020 NEXT /
where / is again your auto-increment
value, Y is the base address + 1, and
A[I) is your data array. Remember^
though, this is just an example of how
to read and write data to the RAM
cache, just to show you how it is done.
You can use any method you choose.
One point to keep in mind: Before you
access a page, you must store the proper
page number in the base address. This
also clears your auto-increment counter
to make sureyoustart atthe right place.
You wouldn't want to start in the mid-
dle.

[Powerful [Pages
By Matt Krom
Here's a short little program that demonstrates a very
powerful capability of the CoCo called "page-flipping." Just
run Listing I, sit back, and watch! What you see is actually
four separate screens being rapidly switched, much like
flipping pages of a book. This creates the illusion of motion.
Line 60 erases the first four graphics pages to white. These
four pages will be used by the program as the four separate
pictures.
Lines 80 to 110 set the computer to PMODE 0 and draw
large letters spelling "Hi!" You can change these lines to
draw anything you like. This is the drawing that will be in
front of the moving grid. Line 130 then copies this drawing
from the first page to the other three pages.
Lines 140 to 240 are the lines that draw the grid on the
four pages. These lines may be a little difficult to under-
stand, but if you carefully study the formulas in lines 190
and 230, you will see that each grid is moved down and to
the right of the grid on the previous page. The grid lines
do not affect the drawing because they are of the same color.
The infinite loop in lines 250 to 290 then displays the pages
in sequence, and the animation appears!
But how do you draw on the different pages? The secret
here is the PMODE 0, x statement, where x denotes a number
telling the computer what page to go to. For example, say
you want to make a program in which a circle goes
horizontally across the screen. The program should first set
the computer to Page 1 by using PMODE 0,1. Then draw a
circle at the desired location. Now use PMODE 0 , 2 and draw
a circle a little to the right of the last one. Continue this
procedure until you have drawn on as many pages as you
want. When using PMODE 0, the number of pages can range
from 1 to 8.
Listing 2 is a program like the one just described. It is
less involved than the first, so programmers who are new
to this technique should study it more closely. The PCLERR
B statement was necessary to reserve enough memory for
the eight graphics pages.

A Coordinated Effort
Using the hardware joystick/ mouse cartridge from
CoCo MAX in your own programs is a snap! The
address map for the cartridge is as follows.
SFF90 Button value — 0 if button is pressed
$FF9 1 Vertical coordinate (0-255)
SFF92 Horizontal coordinate (0-255)
The port can be accessed directly in BASIC or
BASIC09 using peeks to the given location. For
example, in BASIC09 you would use the following code
to find the horizontal coordinate:
DIM xposrBYTE
xpos = PEEK($ff92)
Some operational notes are in order here. First, the
vertical coordinate can be anything from 0 to 255 but
•the screen only uses 0 to 191. You should use a
conditional statement to check for this. Second, in
OS-9 the vertical coordinates are reversed so you
should subtract the actual value from 255 to get the
proper location.

Utilities
AnOnsideWiew
By Michael Berenz
Disk Seek is a simple program that allows you to view the
contents of a disk. Upon running, the program prompts you
to place a disk in the drive. The current track and sector
appear at the bottom of the screen. The up and down arrow
keys change the track, and the left and right arrow keys
change the sector. Moving up from Sector 18 will bring you
to Sector 1 on the next track, and vice versa. You need not
repeatedly press a key because of the peeks in Line 150.
Holding the key down will suffice.
The program does not allow for editing of sectors, but
is simply a fun little utility that tells you just what your
drives are writing as they chomp away at your disks.

Prompt Attention
By Joseph Forgione
Are you tired of the color-changing cursor and OK
prompt on your CoCo? Conversion will allow you to change
it.
Upon running, the OK prompt will be replaced by
"Ready." However, for Conversion to work properly, you
must be in the "all-RAM" mode. This means your CoCo
must have all the ROM copied into RAM and be running
entirely from RAM memory. Some DOSs have special
commands allowing this, and the CoCo 3 is always in the
RAM mode. But if you are using a standard Radio Shack
CoCo 1 or 2 system, you can enter the RAM mode by first
running Listing 1, DRIVER.
Then, by running CONVERT, you can change the color of
the cursor by entering POKE 1023, xxx where xxx is the
appropriate value from the following table:
Black 128
Green (invisible) 143
Yellow 159
Blue 175
Red 191
White 207
Blue/ Green 223
Purple 239
Orange 255
For example, if you want to change the cursor color to
purple, type POKE 1023,239 after running CONVERT.
Some program notes are in order. First, if you have the
HJL keyboard, Line 110 allows you to use the F4 key to
pause a screen scroll (works like SHlFT-@). If you do not
have the HJL or similar keyboard, remove Line 1 10.
Second, if you want to retain the OK prompt, remove
Line 90; if you want to retain the old cursor, remove lines
50, 60 and 70.
Finally, the program changes the message you receive
when you press the BREAK key (Line 150). Instead of
printing "Break In," the computer will respond with "Break
At."

[Backup And
By Matt Lawson
CoCo 3
Disk
Anyone who has ever made a disk backup knows how
tedious it is switching disks back and forth. However, now,
with Fast Copy and any disk-based Color Computer 3, the
problem can be eliminated.
Upon running the program, the computer asks if it should
report errors to the printer or screen, then prompts you to
insert the source disk (the disk to copy). The drive will churn
for about 40 seconds and then ask for the destination disk
(the disk to be copied to). This procedure must be repeated
only one time before the disk copy is complete.
If the disk drive should encounter an error, the error type
and where it occurred are reported. Note: The copying
procedure does not stop for a disk error. This way, all of
the intact data on the source disk can be copied, while the
bad data could never be read again anyway. If you should
encounter ^Write Error, it will be necessary to reformat
the destination disk and start over.
By the time the program finishes, most of the computer's
memory is filled with disk data, so after making a backup,
you should turn off the computer to achieve a cold start
before doing anything else.
How It Works
The computer reads (or writes) half the disk at a time with
the buffer in virtual memory locations (Hex) $60000 to
S6FFFF and $74000 to S77FFF The program uses a
machine language ROM routine so that the user is not
stopped with an ?IO Error message.
It appears as though the only memory locations used are
$4000 to S7FFF. However, the CoCo 3 has a method of re-
arranging the memory map with a chip called the Dynamic
Address Translator (DAT). The computer fills up $4000 to
$5FFF, then swaps it for a different portion of memory,
even though it uses the same addresses. One interesting,
important note: The DAT switches are located at $FFA0
to $FFA7.
The ability to copy around disk errors should be a
welcome feature to every disk owner.

98 THE RAINBOW July 1 987
The 1987 Chicago RAINBOWfest went very smoothly. While the terms "relaxed" and "excited" seem
contradictory, they best describe the atmosphere at this show. Both exhibitors and attendees knew
exactly why they were there and what they were doing, but they were clearly excited about all
the new things to see. However, few were as excited as 3-year-old Austin Holt (above). Austin had
known for two weeks that CoCo Cat would be making a first-time appearance and travelled all the
way from Brandon, South Dakota, to see the fuzzy feline. The words Austin used to describe the meeting,
"I love him!", are evident in his smile.

ASSEMBLY TUTORIAL
CoCo 3

OS-9
Level II
A Computer's Ancient
Native Language
Bv Peter Dibble
Sorcery books are almost unani-
mous: The most potent spells are
written in strange, usually an-
cient, languages. It works the same way
for computers. The most profound
magic forthe Color Computer is written
in assembly language, the ancient native
language of OS-9.
I want to include some assembly
language code here, but there is a
problem. Tandy chose not to include an
assembler with OS-9 Level II. Old-
timers will have the assembler from
Level I. It works under Level II, but the
defs files are incorrect. (The Level I
defs files usually fit Level II, provided
you stay out of the system data struc-
tures.) In any case, I will assume you
don't have an assembler.
The assembler converts assembly
language programs into modules. I
could save you the trouble of typing in
the program, if I could print the module
here. However, modules are full of
unprintable characters and RAINBOW is
unable to print them.
This month's programs are a solution
to the assembly language problem.
CDump converts any file into a printable
format. Il is the program that I will use
to encode modules so RAINBOW can
print them. If you want to use it, type
CDump into BASIC09 and save it to a disk
file. Run CDump and tell it the name of
the file to print. Wait while it writes
CDump . output. CDump. output con-
tains a printable code thai can be
converted back into the original file.
When I asked CDump to encode the
CDump source, the first few lines of
CDump. output were:
1: 5052 4F43 4544 5552 4520 B0B26.
2: 4344 756D 700D 4449 4D20 78478.
3: 496E 4669 6C65 2C4F 7574 87306.
Peter Dibble has a bachelor's degree in
chemistry and is currently a graduate
student in computer science. He has
worked as an applications programmer,
systems programmer and as the user
services assistant director for the Uni-
versity of Rochester Computing Center.
With Dale Puckett, he is the co-author
of The Complete Rainbow Guide to
OS-9.
If you have a good text editor, you
might want to modify CSave so it works
with input from a file. You should
require check codes in the input and
quit when you find an incorrect check
code.
CDump and CSave were written to
solve the problem of the missing as-
sembler, but they have other uses.
CDump encodes any file in a printable
format with error-detection codes.
CSave decodes the file and checks the
codes. Use them any time you need to
send a file through a process that insists
on printable characters and may be
unreliable. For instance, if you want to
send a module to an IBM mainframe
over the phone line, you might want to
send the CDumped code for the file. □

Each line has three parts: A line
number, codes for 10 bytes of data and
a check code for that line. You can use
CSave to decode the output from
CDump. To use it, type CSave into
BASIC09 and save it to a disk file. Run
CSave and tell it where to put the
decoded file, then follow the directions
CSave gives.
CSave prompts for input one line at
a time. For each line, enter the five,
four-character words of data and press
ENTER. For instance, if line one from
CDump is:
: 5052 4F43 4544 5552 4520 B0B26-
you should respond:
I 5052 4F43 4544 5552 4520
when CSave prompts you for the first
line. You may leave out the spaces if you
like.
CSave computes a check code for the
line and asks you if it is correct. If the
code CSave calculates matches the one
that CDump put at the end of the line,
you probably typed the line correctly.
Tell CSave you are content with the line
by responding with a T to the question:
"Right?" If you respond with an F,
CSave prompts you to enter the same
line again. After you have entered all the
lines, and CSave prompts you for
another line, press CTRL-BREAK to
indicate end of file.

Trivia hysteria hits our national pastime
By T.C. Taulli
'ver since Trivial Pursuit burst onto the board game
Lscene, trivia has affected us in one way or another. Let's
Iface it, it's fun to show your friend or opponent how
intelligent you are. Beating someone in a game that requires
your ability to think and recall information provides
immense satisfaction, not to mention a boost to your ego.
For those who are Machiavellian adherents, trivia is an
excellent, nonviolent means of revenge.
When playing trivia games, you must be careful. You
don't want to be known for having the IQ of a doorknob.
Relax and let your mind fetch the information. Psycholo-
gists have proven that we remember everything. The only
thing preventing you from taking advantage of your
memory is your attitude. If you say you can't, you're telling
your subconscious to accomplish the task.
In Latin, the word "trivia" means "belonging to
the crossroads," hence "commonplace." This
seems inaccurate. Trivia exercises your
mind, builds up that hunk of gray
mass while providing fun. It was
Edmund Burke who said that "the
wisest in council, the ablest in debate, and the most
agreeable in the commerce of life, is that man who has
assimilated to his understanding the greatest number of
facts."
T.C. Taulli lives in Monrovia, California, and is the author
of Do or Die. T.C. is a member of I he Color America Users
Group.

Since baseball is our national pastime, what would be
more appropriate than having a program that tests your
ability to answer questions about the game? But, beware!
It's not as easy as you might think. The questions Tve
included cover many years, from Ty Cobb to Nolan Ryan
— all the greats who fill the Hall of Fame.
My questions are fair. For example: Who was called the
Bambino? And, of course, the answer is Babe Ruth. The
questions are not like this: At what time in the day did Babe
Ruth tie his shoes on October 2, 1930?
The program has several questions to fill your mind, to
force you to concentrate and to learn. You don't have to
worry about typing in the answer. The program is joystick
controlled. I've also used Hi- Res graphics to make the
program more attractive. We can't have anything but the
best for baseball trivia. □
Editor's Note: While the original program includes
120 questions, the following listing only includes
30. This is due to magazine space considerations.
However, the 120-question version will be included
on RAINBOW ON DISK and RAINBOW ON TAPE.

to a few minor errors in his program, Graphii, While
the program appears to work normally, some of the
output will be incorrect. To correct these errors, alter
the following lines accordingly:

July 1987 THE RAINBOW 111
Keying Into CoCo's Power
By Fred B. Scerbo
Rainbow Contributing Editor
Editor's Note: If you have an idea for
the " Wishing Well, " submit it to Fred
c/o THE RAINBOW. Remember, keep
your ideas specific, and don 7 forget that
this is BASIC. All programs resulting
from your wishes are for your use, but
remain the property of the author.
I hope that you all enjoyed our little
graphics experiments in the last two
issues of THE RAINBOW. Both pro-
grams were the direct result of sugges-
tions sent in by readers who use the
Color Computer to educationally mo-
tivate their children. In recent months,
I have received even more letters along
the same line. We will take a look at
what a few of these readers have had to
say and then launch into another wish
that took a little time to develop but will
satisfy those of you who want to intro-
duce the very young to computer skills.
The program is called CoCo Keys and
can be used with or without the Radio
Shack Sound/ Speech Cartridge.
Fred Scerbo is a
special needs in-
structor for the
North Adams Pub-
lic Schools in North
Adams, Massachu-
setts. He holds a
master's in educa-
tion and has published some of the first
software available for the Color Com-
puter through his software firm, Illus-
trated Memory Banks.
What Readers Say
Sometimes I spend a great deal of
time developing an educational pro-
gram only to have one of my students
dismiss it with a wise-guy remark like,
"Couldn't you come up with anything
better than that?" I am often tempted to
dare them to come up with something
better, but that would be a rather cheap
way of soothing my bruised ego. In-
stead, I can counteract their remarks by
turning to the reader mail, which arrives
every few days. Since it is impossible to
respond to these letters individually, I
will take a crack at a few of them here.
Several readers have commented that
they have had difficulty getting some of
these talking programs to work, espe-
cially on the CoCo 3. Since I haven't
made the jump to CoCo 3 yet, I am not
sure whether any changes are needed to
make speech programs work when the
CoCo 3 is in its CoCo 2 mode. Shirley
Moncrief of Hayward, California, ran
into this problem. The program works
perfectly with no error messages, but it
just won't speak. There are two possible
fixes for this.
First, sometimes the Voice Pak can be
reactivated by pressing the reset button
several times. 1 have run into this
problem on my CoCo 1 and 2 every so
often. For some reason, sometimes the
Pak just seems to not engage.
Second, recheck the listing directly
after the title card at the section where
you select talking or non-talking. It is
possible that the non-talking variable
may have been accidentally typed into
both lines. Naturally, there is a different
value for each, so it is possible that if
the wrong value were typed into the
talking line, it might make the program
ignore the talking subroutines when the
program is running. Again, to be safe,
subscribe to RAINBOW ON TAPE and you
will get a bug-free version every time.
(No, the magazine listings do not have
bugs in them. Those seem to creep into
your CoCo somewhere between the
pages and your typing fingers. A pro-
gram need not show an error message
to have a typo in it!)
Mae R. Hipp of Sun Valley, Nevada,
had a little problem with our under-
standing relationships between frac-
tions, decimals and whole numbers
program in the January 1987 column.
The caret, or little upward pointing
sign, in Line 210 after the varible R=10
is actually the up arrow on your key-
board . My lineprinter (an Okidata 82A)
prints that figure as an arrow, but
apparently the rainbow's professional
lineprinter uses the up caret instead. If
you see an up caret in any of these
listings, be sure to use the up arrow
when you type in the program. (Also,
be sure to type it in correctly the first
time, since if you try to edit it into the
line using the EDIT command, you will
not be able to. Using the up arrow exits
the EDIT mode in Extended Color
BASIC.)
This Month's Idea
Sonya Hurst of Richmond, Califor-
nia, wrote a letter that served as the
inspiration for this month's program.
On a very colorful letterhead she ob-

computer keyboard on the screen and
put the letters and numbers on the
keys. This was to be part of a spelling
program for my 5-year-oid daughter.
I wanted to have the Speech/ Sound
Cartridge ask her to spell a word. If
she spelled it incorrectly, I wanted the
proper letters to be highlighted on the
screen so she could see them, one at
a time ... I can get the picture of the
keyboard, but not the letters.
She then included a short listing that
would draw the keys on the screen.
Rather than take this idea all by itself,
I decided to write an entirely new
routine that would draw a very precise
keyboard with all the little details that
I could cram into the resolution of
PM0DE4.
If you recall, my last two programs
included a new graphics text routine
that helped do the explaining about the
blood and your heart. I tried this with
our Speech Pak and even managed to
get the results displayed in PMDDE2/1,
rather than PMDDE 4^3. However, using
PMQDE2/1 would not give me enough
detail to display the text for our double-
duty keys on our CoCo keyboard (such
as those that have shift characters).
Therefore, it was necessary to make a
few changes in this routine to get it to
work in PMQDE4. Even the DRTR state-
ments had to be changed.
The resulting program, CoCo Keys,
is not the spelling program that Ms.
Hurst was trying to write but, instead,
is a very elementary (but classy looking)
keyboard ing program that introduces
the user to the workings of the CoCo
keyboard. It is not a typing tutor pro-
gram. Rather, it is a program that will
help the very young or very inexpe-
rienced to become more familiar with
where to find specific keys on the
keyboard.
Before we wrap up, I will also show
you how to merge my graphics key-
board into your own BASIC keyboard
program. With that in mind, let's launch
into how to use CoCo Keys.
Using the Program
CoCo Keys uses the PCLERRB com-
mand, so some older CoCo 1 models
may give a syntax error when the pro-
gram is first run. Simply re-run the
program to proceed, or type PCLERR B
before running or loading the program.
To start the program, enter RUN. If a
red screen appears, press ENTER to
continue. If the screen is blue, press
reset and run it until the screen appears
red. Then you may proceed with a full-
scale running of the listing.
On running the program, you get our
very familiar "Wishing Well" title
screen. You are asked to choose between
(T)alking or (N)ot by pressing the
appropriate key. CoCo Keys does not
need speech to be run effectively. If you
choose non-talking, you may read the
text to a child who is using the program.
It can be just as effective when used this
way. In fact, it can be more effective if
the child cannot understand the
computer's artificial speech.
The screen will make a slight pause
while it is jumbling the order of the keys.
The screen will then display 58 different
keys f or the user to find and press when
prompted. Pressing the correct key will
cause that key to be highlighted on the
screen. Another choice will then be
displayed quickly.
Granted, it may not seem to be much,
but creating the keyboard was quite
time-consuming. It will be put to use in
other programs in later issues. Besides,
you may want to use it yourself.
In any case, CoCo Keys can be a good
introduction to coordinating key-
strokes with visual and speech prompts.
When using the Speech Pak, the com-
puter will say which key it wants
pressed. If you press the correct key, the
key flashes on the screen and the com-
puter speaks a correct response to you.
If you press the wrong key, the screen
flashes green and waits for you to try
again.
A few warnings: Do not press the
keys too quickly because your CoCo
holds a number of keystrokes in its
buffer. You may press several keys and
end up with several incorrect responses.
Also, be sure to shift for the shifted
characters on the keyboard. If you press
without the SHIFT, the response is
wrong. If you want to check your
progress, press SHIFT-CLEAR to go to
the scorecard. You will see how well you
have done and may choose to either
start over, end or press C to continue
where you left off.
Using the Graphic Keyboard
There is a very simple way to remove
the graphic of the keyboard from this
program if you have a disk. Run the
program up to the point where the
keyboard is drawn and then press
BREAK before the text is printed at the
bottom of the screen. With a disk in the
drive, type:
5RVEM"KEYBRD",35B4, 9727 , 0
and press ENTER. The graphic of the
keyboard will now be saved to disk. You
may reload it into your own program by
including a line with:
PM0DE4,1:5CREEN1,1:LDRDM' /
KEYBRD"
July 1987 THE RAINBOW 115
This will reload the keyboard to your
screen. The DflTR statements include the
locations of each key and character.
If you do not have a disk drive, you
would have to use most of the program
lines listed here. Anyone wanting to use
the keyboard graphic in their own home
programs is free to do so. However,
please do not ask me if you may use it
in a commercial program. The answer
is no.
While this program may seem almost
pre-school, believe me, older users will
not get a perfect score the first time. It
can be very valuable for learning where
things are on your keyboard. In fact,
very soon you may see this graphic
included in an educational game I am
working on. Until then, keep your
letters and requests coming in. They are
getting better all the time. □

120 THE RAINBOW July 1987
Some of you may have been won-
dering about recent changes in
the opening banners for the CoCo
and OS9 Online SIGs. Because of my
ever-increasing duties here at RAl NBOW,
and also because of the type of work
Marty Goodman (martygoodman)
has been doing in the CoCo SIG, Marty
has officially been named SIGop of the
CoCo SIG. For some time now Don
Hutchison (DONHUTCHISON) has been
doing quite a bit of work in the database
areas and, therefore, when Marty was
named SIGop, Don is placed in charge
of the CoCo SIG databases. I will
continue to write "Delphi Bureau" each
month and serve as rainbow's "techni-
cal liaison" to the CoCo SIG. However,
to reflect the change in database man-
agers, Don is also taking over Marty's
duties in writing the Database Manag-
er's report.
In the OS9 Online SIG, Greg Law
(GREGLAW) has been spending greater
amounts of online time handling "staff"
matters. At the same time, Dale Lear
(DALELEAR) has found that he has been
unable to be online as much as he would
like due to work and family. To reflect
this, Greg has been officially named the
SIGop of the OS-9 Online SIG. Dale
has agreed to stay with the SIG and,
along with Rick Adams (RlCKADAMS),
serve in the capacity of OS-9 Consul-
tant.
Jim Reed (JIMREED) remains the
Group manager for both SIGs as well
as r or the Aviation SIG recently formed
for NEW pilot by Falsoft.
These changes more accurately re-
flect the work actually being done by the
various staff members. We believe they
are in the best interest of all concerned
and believe you will agree. Please take
a moment online to welcome these
people to their new positions and show
them your support.
This month's "Delphi Bureau" will
run rather short so that we can bring
you the map of the CoCo SIG. Actually,
we created this map for the "Intro to the
Delphi SIGs" seminar at the recent
Chicago RAINBOWfest. It seemed to
be a great help to people there, so we
decided to publish it here.
DATABASE REPORT
The latest Chicago RAINBOWfest
was a huge success!
Our Delphi booth was manned by
Rusty Williams (rusty) of Delphi's
marketing division and Marty Goodman
(MARTYGOODMAN) from the SIGs. Vis-
itors to RAINBOWfest noted that Marty
added his usual color and pageantry to
the booth, while Rusty provided a pro-
fessional touch to the operation. Roger
Bouchard (HARB1E), Steve Bjork
(6809ER), Erik Gavriluk (ERlKGAV) and
Greg Miller (gregmiller) also spent
considerable time at the Delphi booth
and helped to make it a success.
Several CoCo SIG and OS-9 Online
staff members contributed time, provid-
ing online demonstrations to prospective
Delphi members during the show. At
various times, Rick Adams (RlCKA-
DAMS), Greg Law (gregl), Richard
Esposito (doctorascii) and 1, Don
Hutchison (donhutchison), were f ound
online from different areas of the country

July 1987 THE RAINBOW 121
demonstrating the instantaneous com-
munications that Delphi offers. The
conference area of the CoCo SIG fea-
tured a nearly continuous online conver-
sation entitled "Live from RA1NBOW-
fest." Rick Adams amused the online
crowd continuously by demonstrating
the humorous macros he uses with Rick-
eyterm, the CoCo 3 terminal program he
authored.
Other Delphi regulars present were
Kevin Darling (KDARL1NG), Roy Cosby
(uncle) and Art Flexser (artflexser).
Of course, most of the rainbow staff was
present, including Lonnie Falk (lfalk),
Jim Reed (JIMREED), Dan Downard
(dandownard) and Cray Augsburg
(CRAY).
OS-9 Online
We are getting a good number of
uploads, as more and more of our
members acquire OS-9 Level II and begin
to spend their time learning about it.
In the General Information section of
the OS-9 Online service, Bill Brady
(wbrady) gave us a file called WI Z. PRD,
which describes his new terminal pro-
gram The Wiz, to be marketed by Frank
Hogg.
In the Utilities section, Dennis Weldy
(OS9ER) gave us his BASIC09 alarm pro-
gram. This utility will cause a beep after
one minute.
In the Patches topic area, Karl Quinn
(qkq) sent us a file for fixing DynaCalc
to eliminate two bugs in off-the-shelf OS-
9 DynaCalc from Tandy. Bruce On-
dersma (beo) sent us instructions on
using Profile under Level II of OS-9. Jim
Manning (J 1MBM) sent us a file describing
how to patch your drives /DO and /Dl
to use 40 tracks instead of 35 on OS-9
Level II.
In the Graphics area, Bob Montowski
(GRAPHICSPUB) sent us his SHOW09 pro-
gram set for viewing DS-69 16-level
digitized pictures under OS-9 Level II on
the CoCo 3.
In the Telcom topic area, Randy Long-
shore (randyf) provided us with the
COM09 package. These files constitute a
terminal package written in BAS1C09. It
has many useful features, including a
keystroke-multiplier file for automatic
logins and automatic logging to disk for
recording a conference session or saving
messages from the Forum. It was written
by Jason Shouler of the United Kingdom
and is public domain software.
The Users Group area enjoyed the
most new additions, with 1 1 new submis-
sions, due to the hard work of SysOp
Greg Law; ACIA Mapin, a filter to
change control strings from a terminal
into corresponding ANSI strings; ACIA
Mapout, an appendage for the ACIA
driver to get control of ini t, read and
write and pass them through ACIA to
the physical device; Arc, an archive
utility useful for backing up a hard disk
to multiple floppies; XCOM9, a terminal
program for OS-9 that supports Xmo-
dem file transfers and has an extremely
high throughput; Append and AP, file
append utilities; Antenna, which designs
amateur radio VHF long yagi antennas;
Amort, which prints a complete amorti-
zation schedule to screen or printer;
Alias, which creates a program in the
current execution directory with the
name newname; Advent, which is an
Adventure game for OS-9; and AD J,
which limits maximum line length in a
text file without splitting words.
CoCo SIG
In the General Information topic area,
Marty Goodman posted a report on the
1987 Chicago RAINBOWfest. David
Kay (peashooter) furnished us with an
amusing article concerning IBM compat-
ibility.
Medical articles increased this month,
starting with CDC03CPR . BR5 by Dave
Schaefer (daveschaefer). Joe Carney
(joecarney) posted his response to
Marty Goodman's article concerning the
"war on drugs." Soon thereafter, Marty
Goodman posted his reply to Joe Carney.
In the Utilities section, Roger Krupski
(HARDWAREHACK) provided us with
ERRDRV.BIN, a utility for printing more
descriptive error messages from BASIC.
Charles Pippin (cwp) gave us his Check-
pro program for keeping up with the
monthly budget. Mike Fischer (M1KE88)
gave us a nifty BBS cataloguer program
for the CoCo 3, as well as a long list of
his favorite BBSs. David Brown (NASAi)
gave us 5CRDLL.BR5, an experimental
program for scrolling messages across
the screen of your CoCo 3, and David
Ferreira (skeeve) posted his latest ver-
sion of the OMGUTL programs.
In the Hardware area, Marty Good-
man posted an article on his favorite
places to purchase chips.
The Graphics section received a large
number of new files. First, the "CoCo
Galleries" for February and May 1987
arrived. Of notable mention is the entry
from the May issue entitled Seascape,
drawn using CoCo BASIC by James Up-
perman. It features an animated night
scene of a man beside a fire at the beach.
This picture is for the CoCo 3.
David Brown gave us PRLETTE . BR5.
Billy Hambric (SNOOPYDOG) gave us
MRXHDRDM.PIX, a digitized picture from
the Max Headroom show. This picture
was used, in turn, by Erik Gavriluk to
produce his Color Max Headroom dem-
onstration program. Alan DeKok ( ALAN-
dekok.) gave us his version of the Rock-
fest 1+2 programs for the CoCo 3. Mike
Fischer pleased us with his Spectrum
BBS demo for the CoCo 3. This program
features, among other things, a moving
text display at the bottom of the screen.
Along the same lines, Jim Sparks (ESCO
man) gave us his BBS logo featuring an
animated, old-fashioned buckboard
wagon.
For those interested in exercise, Rick
Adams donated an interesting sight V
sound Jumping Jacks program, which
features a young woman performing her
exercises in time with the background
music. Bob Wharton (BOBWHARTON)
sent us a great collection of Garfield
pictures drawn for the CoCo 3.
Greg Miller donated two utilities for
use with Color Max 3 pictures: bsctool
and Gallery. Gallery is a stand-alone
program that lets you load and view
Color Max 3 pictures, while BSCTOOL is
a basic "tool"that allows you to load and
view the pictures from within a BASIC
program; it is intended to be used as a
subroutine. Greg also generously gave us
F4E.MGE, one of the first pictures ever
drawn with Color Max 3. Drawn by Jeff
Shane, it is a picture of a camouflaged jet
fighter plane.
In the Games topic area, Steven Macri
(dracman) posted a revision to his
popular Kelly checkers program. Daryl
Kent (DJKENT) gave us his Color Kismet
game, and Michael Brant (mbrant)
favored us with a set of "chronology"
files. While intended for use in a trivia
game, these files also serve as an educa-
tional aid for school children.
In the Music topic area, we were
extremely fortunate to receive 71
Orchestra-90/ CC files from such notable
contributors as Bryan Eggers (SOFTAF-
FAlR), Jerry Bradshaw (JOB45), David
Browder (dbrowder), Bill Teeters
(clambake), Larry Wimble (theas-
SEMBLER), Ron Cook (COOKY) and Gary
McCarty (bandman). The files were
transferred to us from the Tandy SIG
following the acquisition of that SIG by
Falsoft, Inc.
Additionally, Marc Genois (marc-
GENOis) favored us with a well-done
collection of songs from the group Gene-
sis, and Bill Starr (wstarr) provided us
with five more Orchestra-90/ CC files:
Ragtime Night, Spring Song, Cradle,
Bossa Nova and Top Gun.
The coming month on the CoCo SIG
may see the publication of Version 2.0 of
Rickeyterm, which will support the bit-
banger serial port on the CoCo 3 at 300
and 1200 baud. For sure, more
Orchestra-90 music files are on the way.
In the OS-9 SIG, members will con-
tinue to see more of what will eventually
become five megabytes of OS-9 Users
Group files. The OS-9 Online staff is now
hard at work creating this new topic area.
Also, we are expecting a huge influx of
files concerned with using and modifying
OS-9 Level II, as more SIG members
purchase it and begin to use it. See you
online!

122 THE RAINBOW July 1987
What you can and can't do
with someone else's progra
You Ve purchased a computer pro-
gram on tape or disk, typed it in
from THE rainbow, down-
loaded it from a bulletin board, or
borrowed it from a friend. Now you'd
like to make copies of the program, alter
it, send copies to your friends, or adapt
certain subroutines or programming
techniques for use in your own pro-
grams. Under the copyright law, which
of these things are you allowed to do?
Copyright law, in a nutshell, provides
that a person who owns the copyright
of a computer program has the "exclu-
sive" rights to copy the program, dis-
tribute copies of the program or to
make adaptations that are substantially
similar to the program. Anyone else
who copies or distributes copies of the
program beyond the exceptions pro-
vided in the copyright law infringes the
copyright, unless the owner grants
permission, which will usually be con-
ditional upon payment of a royalty fee
or purchase of an authorized copy of the
program.
I want to discuss the exceptions to
this rule: the limited rights of the person
who has a copy of a computer program
to use the program, to sell or give away
the copy, to make backup copies and
adaptations, or to use the "idea" of the
program. I will also consider programs
that are in the public domain.
Using the Computer Program
If you obtained an authorized copy of
thecomputer program f rom a magazine
or a bulletin board, or by purchase, then
you most certainly have the right to use
the program — that is, to load it into

New York Law School, has taught

more than 10 years. An avid reader of
RAINBOW, Professor Samuels enjoys

year-old Richard and 4-year-old Claire.

your CoCo and run it. By making the
work available to you, the author has I
granted you a license to use it for its
intended purpose.
If, however, you obtained an unau-
thorized copy of a program — from a
friend or from a bulletin board, or by
purchase from someone who made an
unauthorized copy — then there is no
implied license from the copyright
owner to use it. When you load the
program into your CoCo to run it, you
are making a further unauthorized copy
and infringe the copyright owner's
rights.
Selling, Giving Away, or Lending Your
Copy of the Program
If you obtained an authorized copy of
a program, you may clearly sell that
particular copy or give it away to a
friend. For example, if you buy a game
contained in a ROM pack, or on a disk,
and you want to give away that partic-
ular ROM pack or disk, you may do so,
and neither you nor your friend will
infringe the copyright owner's copy-
right. The legal principle that allows this
is called the "first sale doctrine." The
presumption is that the copyright owner
was paid a royalty when the copy of the
work was originally sold and is not
entitled to a second payment for the
resale of that particular copy. However,
this theory would not allow you to make
copies of the program to distribute to
f riends, whether f or a f ee, f or f ree, or as
part of a trade. Similarly, if you make
a copy for yourself and give the original
to a friend, the copy that you made is
probably an infringing copy and sub-
jects you to suit under the copyright act.
Under the first sale doctrine, you are
allowed to lend the authorized copy you
obtained or to rent it out, as well as to
sell it. This is what videotape stores are
doing when they buy a popular video-
tape and then rent it to others without
paying any further royalty fees to the
copyright owners.
July 1987 THE RAINBOW 1 2
Making Backup Copies and Adapta-
tions
Under a 1980 amendment to the
copyright law, if you obtained an au-
thorized copy of a copyrighted comput-
er program, you are allowed to make
another copy of that program "for
archival purposes only." This means
that you may make a backup of the
program to use in case anything disas-
trous should befall your original, but
you may not distribute your backup
copy to others.
In addition, the 1980 amendment
provides that you may make an adap-
tation of the program "as an essential
step in the utilization of the computer
program in conjunction with a ma-
chine" if the adaptation "is used in no
other manner. " At the very least, this
means that you may make minor mod-
ifications to a program to make it run
on your particular machine, with your
particular configuration. For example,
you may certainly delete the speed-up
poke to make a program run on a CoCo
that can't handle it or make minor
alterations to make a CoCo 2 program
run on your CoCo 3. Although argu-
ments have been made that this right of
adaptation can be fairly broad, I think
that the intent of the amendment is
fairly narrow, and the amendment
should not be used as an excuse for
making extensive alterations in a pro-
gram to suit the whim of the user.
If you make a backup of the program,
you may sell the backup or give it away
to others in conjunction with the sale or
lease of the original from which you
made the copy. However, if you adapted
a program to make it work on your
machine, you are theoretically not
allowed to sell or give away that adap-
tation when you dispose of the original
program, except by permission of the
copyright owner.
Using the "Idea" of a Copyrighted
Program
If you write computer programs, you
may well get some of your best ideas by
studying programs written by others. In
copyright law, under a principle known
as the "idea-expression dichotomy,"
you are free to create programs that
accomplish the same results as pro-
grams you have studied, so long as you
don't take so much of those programs
as to constitute the "expression" of
them. In practice, trying to distinguish
between unprotected idea and protected
expression is one of the most difficult
problems in all of copyright law.
In a 1986 case decided by a federal
court of appeals, the court found copy-
right infringement even though there
was no verbatim copying, but only
copying of "the structure, sequence and
organization" of the files, screen out-
puts and five particularly significant
subroutines. The court emphasized that
it takes a great deal of time to develop
a sophisticated design of a computer
program and that "the coding process
is a comparatively small part of pro-
gramming." This and other recent cases
make it clear that the scope of copyright
protection is broad and that even non-
literal copying can infringe. To play it
safe, you should try not to copy the
structure, display or subroutines of
copyrighted programs, particularly if
you intend to sell your programs com-
mercially.
This discussion of the idea-
expression dichotomy assumes you are
copying a program you are able to view.
If you play an arcade game without
seeing the program listing, or merely
read a description of a program, then
you probably don't infringe the copy-
right by making another program that
accomplishes a similar result. Even if it
should turn out that your program is
similar, if you had no "access" to the
original program — if you independ-
ently created it without directly copying
either particular coding or structure —
then your work doesn't infringe.
However, you should be aware that
the audiovisual display, particularly of
arcade games, may be separately pro-
tected. For example, the pac-man char-
acter is both copyrighted in its visual
presentation and protected by a trade-
mark in the particular name. You
should not commercially use the PAC-
MAN character, or mislead ingly use the
PAC-MAN name, to describe your prod-
uct. You may say your game plays like
PAC-MAN, if that is a true statement, but
you should not sell the program claim-
ing that it is the PAC-MAN game.
Using Public Domain Materials
The discussion up to now has as-
sumed that the computer program you
intend to copy is copyrighted. However,
this is not always the case; the program
might be in the "public domain." If it
is, you need have no fear of infringing
the copyright in the work, because there
is no copyright in a public domain
work. You can make copies, adapt the
program, or even incorporate it into
your own programs, to your heart's
content. You need not even give credit
to the author of the program, although
it is obviously more courteous to do so.
Since so much depends upon whether
the work is copyrighted or is in the
public domain, it is obviously impor-
tant to be able to tell the difference
between a copyrighted program and a
public domain program. Sometimes
this is easy. If the program contains a
copyright notice, in the form "Copy-
right © 1987 by Edward Samuels," then
someone claims copyright to it, and you
are not free to make copies of the work
except as already discussed. (For a
magazine or ne wsletter, a general copy-
right notice at the beginning of the issue,
as is contained in all issues of THE
RAINBOW, will protect all of the con-
tents of the issue, including individual
programs.)
What if you don't find such a notice?
I can think of several reasons why the
lack of notice doesn't necessarily mean
that the work is in the public domain.
For example, if the copy you obtained
was not authorized by the copyright
owner, then the lack of notice has no
effect in placing the work into the public
domain.
Another example is if the work is not
"published." If a friend who wrote a
program gives you a copy and asks for
your comments, then the work is still
protected by copyright, even though no
notice appears on it. On the other hand,
if the work was published by the author
in a newsletter, or on a general bulletin
board to which the public had access,
or if the work was sold by the author
to anyone who wanted a copy, then it
would probably be considered to have
been published, and lack of notice may
place the work into the public domain.
There are, however, some "savings"
provisions in the copyright law that may
still save the work from going into the
public domain. For example, if the
notice was omitted from "no more than
a relatively small number of copies,"
then the copyright in the work will not
have been lost. Also, if the author
published the work and omitted notice
inadvertently, then the author has five
years to register the work with the
copyright office and affix notice to all
subsequently published copies, thereby
saving the work from going into the
public domain.
As you may gather from this brief
description, there are some cases in
which it is practically impossible to
ascertain whether a program that omits
the copyright notice is in the public
domain or is still subject to copyright,
124 THE RAINBOW July 1987
particularly within the first five years
after publication of the work. If you
plan to distribute copies of such a
program commercially, you put your-
self at risk if you do not or cannot
contact the author to obtain permis-
sion. However, if you rely upon the
absence of notice on an authorized copy
of the program, the recovery that a
copyright owner will be able to obtain
against you will be reduced, in some
cases, to nothing at all. The result
represents a compromise, on the one
hand protecting copyright owners who
may inadvertently omit notice from
some copies, and on the other hand
giving some protection to copyright
users who may innocently infringe a
work, not knowing that it is still subject
to copyright.
But Who's Gonna Know?
Despite what I may say about what
you are "allowed" to do and what you
are "not allowed" to do, people do in
fact copy computer programs. People
share their copies with friends by ex-
change, by gift, through computer clubs
and through computer bulletin boards.
What happens to them when they do so?
Generally nothing.
It is a criminal offense to infringe a
copyright willfully and for purposes of
commercial gain, so don't knowingly
copy computer programs to sell them.
The potential gain is not worth the risk,
however small, of getting convicted,
fined and jailed. But even if you do copy
to exchange or give away software,
there is the possibility that you can, and
may, be sued by the copyright owner.
As a lawyer, I have to point out that
if you infringe, you may be liable for
"statutory damages," that is, between
$250 and $10,000, even if the copyright
owner cannot prove specific injury, and
even if you have made no profit from
your infringement. If you have in-
fringed "willfully," the judge may grant
damages up to $50,000.
Some companies adopt copy-
protection schemes that are supposed to
prevent, or at least reduce, unauthor-
ized copying. Do you infringe the copy-
right if you "break" the protection
scheme to make a copy? Presumably so,
since you clearly make an unauthorized
copy, and you may even create a "de-
rivative work" that omits the copy-
protection scheme from your copy of
the work. Some people argue that this
activity is authorized by the 1980
amendment to the copyright act if you
use the copy "for archival purposes
only," but you certainly infringe if you
distribute the copy or use it in any other
way than as a backup.
Some software companies print
"software license agreements" in their
documentation, describing what the
user may or may not do with the pro-
gram. There is some debate as to
whether these so-called agreements
have any validity. Under traditional
principles of contract law, an "agree-
ment" requires the knowing consent of
both parties. Conditions that are not
disclosed until after the purchaser buys
the product are not knowingly con-
sented to. Some states have passed laws
that specifically approve such software
license agreements. However, I remain
skeptical about the validity of such laws
and such agreements, particularly to the
extent that they may exceed the rights
already allowed under the copyright
law. Of course, the copyright law is still
applicable.
I'm afraid I don't have the ultimate
answer to the computer copyright di-
lemma. Computer programs sometimes
cost a lot of money to develop, but a
user can usually, with little or no diffi-
culty, make an unauthorized copy. If
too many users make their own copies,
the programmer's profits are undercut,
and the programmer is less likely to
make the effort to develop programs in
the future. I can only add my voice to
those who have urged that we must
respect the rights of copyright owners.
Otherwise, we will put more good
programmers out of business and ulti-
mately have fewer quality programs.
OK, make your backup copies. But
please, don't copy programs for others
— even if you think it unlikely you'll get
caught — because doing so will destroy
something that is valuable to all of us!

I see what you mean (see next
letter).
The Controversy Continues
Here we go again. Your comment to
Larry Allen (April, 1987) was com-
pletely unnecessary. It's an insult to
listen to you "pros " condemn and judge
the MC-10. Unless you used one, you
wouldn't know that it has 192-by-l 28,
four-color graphics, the enhanced
ROM, RAM disk capabilities, and an
outstanding 80-column word processor.
At a recent Co Co show in Spokane, it
was the MC-10 that got the publicity,
not the CoCo. You might not be aware
of this, but when you advise someone
to dump their MC-10 for a CoCo 3, you
are giving them very bad advice. Drives,
multipacks, OS-9 Speech Paks, modem
packs, cables and an RGB A Composite
monitor cost more than many people
can afford. I try to help tape users
through your magazine because 1 was a
frustrated Co Co user for two years. The
CoCo 3 is extremely touchy and is filled
with "bugs. " You should report the
HPRINT, EDIT, LIST, LPOKE, LPEEK and
Hi-Res screen bugs. Maybe you don't
do enough programming to experience
lost programs and crashed disks. Now
the cure is to patch the CoCo 3 's ROM
and LOflDM DOS on power up. The
CoCo isn't an Atari or Apple, and
LOflDMwg DOS is inexcusable! At this
time I have given up all work on the
CoCo 3 and am concentrating whole-
heartedly on my Atari XL (which, by
the way, is a super computer) and my
CoCo 2 and MC-10. If it came down to
brass tracks, I'd sell all my CoCo hard-
ware/software and buy a J 040 ST with
which the CoCo can never compete. Try
accessing a BBS with an ST running it!
Don 7 condemn my XL because the
CoCo will never have its software;
Koronis Rift and Rescue on Fractulus
are old games I've had for two years!
Have you checked the specs on the Atari
PC? Have you heard of the BLITTER
chip in the ST's 32000-by-32000 resolu-
tion? Atari execs never lost one minute
of sleep over the CoCo 3.
Jay Thomas
Great Falls, MT
Apparently, Larry Allen disagrees
with you (see his letter above). I
still stand by my recommendation:
Don't waste money upgrading an "or-
phan" computer of which the MC-10 is
one. Everything you mentioned —
drives, multipacks, OS-9 Speech Paks,
cables, and RGBA monitors — are
optional. The CoCo 3 works fine with
tape. A stock, out-of-the~box CoCo 3
will blow away an MC-iO, an Atari XL,
an Apple II /e or any other eight-bit
micro on the market. In fact, in some
ways the CoCo 3 is even superior to
IBM PCs, Atari STs and Amigas. It has
a far superior operating system. IBM
liked it so much that they are cloning
it for their new Personal System 2. If
you don't believe me, compare the
specs: multitasking, multiuser, win-
dows, UNIXlike — sound familiar?
This isn't the first time IBM cloned
CoCo software, IBM's BASICA has its
roots in Extended Color BASIC. The ST
is a nice piece of hardware, but it's
saddled with TOS. The AMIGA is
stuck with Amiga DOS. Sure, there are
some OS-9 ports to these machines, but
the CoCo 3 is the only one of the bunch
with an OS-9 that is officially supported
by its manufacturer.
Why is it OK to have to load a DOS
into other machines but not the CoCo?
Notthatyou needto;Disk BASIC 1.1 has
been around for quite a while, and it is
the same DOS used with the CoCo 3,
Sloppy programming can get you into
trouble quicker on the CoCo 3 than
with the CoCos 1 and 2 because with it,
BASIC is in RAM and you can modify
this code, either intentionally or by
mistake,
CoCo 3 Pascal
/ have a CoCo 3 and want to know
if it is possible to get the DEFT
Pascal Compiler and DEFT Linker
to work with it. Programs that I created
using my CoCo 2, which worked just
fine, now result in a screen full of errors
on my 3, Everything works until I try
to link a program. Can you tell me if a
new version will be available for the new
CoCo and how much it will cost?
Joe S, A Iderman

Newington, CT
DEFT Systems, at this writing,
has not yet announced a CoCo 3
version, and copy protection increases
the problem of patching the old version;
however, the PASCAL of choice on the
CoCo 3 will be the OS-9 version, for the
CoCo 3 was designed specifically with
that OS in mind (128K to 5I2K, 80-
column display).
Ink Jet Graphics
/ have an Olivetti PR2300 Ink Jet
Printer that presents a problem.
When I wrote a small screen
dump program and used it with my
printer, the pictures came out with 32
vertical bars over them. I believe they
are a type of binary code to identify the
character as a number or as a letter for
the device. I have had this problem for
a year now and would appreciate any
help you can give,
Rick Hamilton
Jacksonville, FL
|/ The only explanation I can offer
jL for this phenomenon, since I do
not have access to such a printer and
you supplied neither copies of the code
nor the documentation^ is that some-
how not enough graphics information is
being sent by your program to be pro-
cessed by the printer. I base this on the
fact that there are 32 bytes per line of
graphics information, and there are 32
bars being printed by your printer, I
assume your program has three loops
where loop one controls the number of
times looptwo is executed to process an
entire screen in steps of L. Loop two
loops from lines L through L+N-l
where L is the starting line of a partic-
ular sweep and N is the number of pins
or jets on your print head that are used
for bit image graphics. Loop three
extracts the appropriate bit from each
of the N lines and fills a byte(s) to be
passed to the printer. In this third loop
is where I suspect that you are not
supplying the value for the final bit of
each byte.
Beginning With Assembly Language
/ have been using a spreadsheet
program for home management pur-
poses. It is not a commercial version
and is written in BASIC. When I first
began using it, I realized it had many
shortcomings, all of which I have over-
come except one; it is horrendously
slow. Interpretation and manipulation
of the cells require a lot of string oper-
ations. With the additions I have made,
mostly in the size of the spreadsheet,
execution time is greatly increased. The
obvious solution was to rewrite the
program in assembly language. Every-
thing progressed well until I got to the
arithmetic. My programming so far has
only dealt with integers; now I am
confronted with fractions. If I under-
stand my texts, fractions must be dealt
with in floating point notation. William
Barden recommends his book Micro-
computer Math in Color Computer
Assembly Language Programming, but
I have not been able to find it anywhere.
Surprisingly, Ltnce LeventhaVs 6809
Assembly Language Programming does
not even mention floating point nota-
tion or fractions. The only information
I have gotten so far explains what
floating point notation is, nothing
more, I understand what it is, I just
don't understand how to use it. My
question is this: Where do I start?
Curt Roberts
Prospect, KY
The MC6809, like most micro-
processors, including the 8088
and the 80286 used in IBM's PC-XT
and PC-AT, does not have any direct
floating point capabilities. Floating
point arithmetic must be done via
subroutines. You can get help on this by
disassembling some of the CoCo's
ROM routines. The CoCo uses two
floating point accumulators for BASIC:
FPAC1, exponent at 54 F, mantissa at
$50 - $53, sign at $54. The correspond-
ing addresses for FPAC2 are $5C, $5D
- $60, and $61. The following ROM
routines should be of interest; subtract
at $B9B9 s add at SB9C2, multiply at
SBACA and divide at $BB8F.
Getting the Sign-On Screen
When I load DOS I.I over the top
of my DOS 1.0 on my CoCo 3, I get
all the commands but I don't get the
sign-on screen for the CoCo 3. How can
I get the sign-on screen?

Assuming that you correctly
patched all of the hooks whenyou
loaded it in, just type EXEC S.HC000.

Boot's Hidden Code
II read with great interest David
Johnson 's letter regarding the boot
program. I have (and use) the same
program myself and have yet to chase
it all down. A machine language pro-
gram does in fact exist, but as far as I
can tell, it is inherent in the Disk BASIC
operating system. If you run the pro-
gram exactly as it is written (lines 10-
90) on a newly powered up machine,
you will get 16 lines of directory listing,
which you may scroll up and can select
and run any program with the push of
a button! My guess is that this is some-
thing that Microsoft left in the coding.
If you can find out anything else on this,
please let me know because I'm baffled
myself!
Mark G. Miller

San Leandro, CA
There is hidden code, but it's right
/C. in front of your eyes, a very clever
machine language program embedded
in the tokenized BASIC commands by
the author Marty Goodman. This code
that is buried inside the BOOT. BPS
program is what provides the up/ down
scroll for the directory display. Conse-
quently, if the code is not typed exactly
as it was originally written, it will not
work. Jerry Dill of Fabyan, Conn.,
reports that David Johnson's version
contained a typo. Line 20 should read:

He added that lines 30 to 70 can be left
out if desired.

Mapper —
A Dynamite
Debugging Tool
Here is a fine utility f or CoCo programmers. Mapper is
a machine language cross-reference tool for BASIC pro-
grams. It will generate listings to screen or printer of all line
number references like GOTO, G05UB, THEN and ELSE
commands. It also generates listings for variable occurren-
ces. The output to screen or printer is formatted and fills
the screen or printer one page at a time. All you need is
a minimum of 16K and any level of BASIC. The program
is simple to use. Just LOflDM "MRPPER" and type EXEC. You
are greeted with a title page with credits and asked for a
title to use for printer output. If you don't have a printer
or don't want a hard-copy printout, just press ENTER. A
second screen appears with the menu of options.
The first thing you will want to do is make a backup copy
of the program for your protection. Instructions are
provided for both tape and disk systems.
Once the BASIC program has been loaded, call Mapper
by typing EXEC and pressing ENTER. Then it's a simple
matter of choosing any of the menu options to locate the
commands, variables or cross-referenced line numbers that
you are looking for. It's a dynamite debugging tool!

Another nice feature is a built-in screen dump option. By
pressing the SHIFT and @ keys, the information displayed
on the screen goes to the printer. This is useful when you
don't want or need the entire listing.
The menu includes five options. The first, Occurrence
Count, scans the program in memory for all the variables
and then lists them in the order of their frequency. The
listing is shown in two parts — simple and array-type
variables. This feature is really valuable for programmers
since it not only shows all of the variables used, but you
can speed up program operation if you initialize variables
in the order in which they are used most.
Option 2, Line-X-Reference, scans the program for all
line number references appearing after a GOTO, GDSLIB, THEN
or ELSE. The output shows the line numbers in the left
column, and the numbers in the right columns are those that
reference that line. This can be invaluable and very time
saving in debugging and modifying programs.
The next option, Variable-X-Reference, scans the
program for all the variables used and then lists them in
alphabetical order with the line numbers they appear in.
Four categories are shown: Numeric, String, Numeric
Arrays and String Arrays. Imagine how easily you can
locate and modify variables scattered throughout a large
BASIC program!
Option 4 is the Command Reference. Here you can type
in the command or string you want to find. All of the line
numbers that it occurs in will be listed. This is a very
powerful option and one that debuggers will love.
The last option, Exit to Basic, lets you select when you
are ready to load your BASIC program for debugging or to
use BASIC to test your program. Re-enter Mapper at any
time by typing EXEC.
I found Mapper to be an excellent utility and one that
any CoCo user will get a lot of benefit from. It's easy to
use and user-friendly, typical of other programs from Bob
van der Poel. In my opinion Mapper represents another hit.
The price is right and you will be delighted to see what it
can do!

Checkbook III Helps Battle
the Big Bank Blues
Checkbook III is a program aimed at tracking money
quickly and efficiently. It is designed to help you manage
your checkbook, from daily transactions right through the
monthly balancing act when your statement arrives. To run
this program, you need a CoCo 3, at least one disk drive,
and, to utilize the program's complete potential, a printer.
What the program does is deceptively simple: You enter
checks, deposits and withdrawals; it tells you your balance.
It stores that information on a disk and lets you look it over
later. But the program does far more than that. It also lets
you define up to nine expense areas, and keeps track of all
expenses incurred in each area. It displays information in
a variety of ways, allowing you to view only the data you
need to see - or all of it ? if you want.
When r unning Checkbook III for the very first time, you
are prompted for some basic information on your account:
name, beginning balance, date opened, and account
number. Here, I discovered one of only two minor flaws in
the program. The account number is stored in a numeric
variable, as opposed to a string variable. Thus, if your
account number is longer than eight digits, it appears as an
exponential equation; my account number is 10 digits long
(1505504351), but it appears in the file as 15055043EI0.
After the account number prompt, you are asked to
define up to nine different expense categories. You may use
as many (or few) as you like. This feature is designed to help
track expenses like rent, groceries, etc. I could have used
more than nine categories (1 tend to get very detailed in this
sort of thing), but nine is more than adequate for the average
person. All the data you enter is written on your disk, and
you are now ready to enter checking account transactions.
The main menu gives a variety of options for entering,
correcting and viewing account transactions. Your options
key off five different types of transactions: checks, ATM
withdrawls, deposits, interest earned and service charges.
You can select any of the above for entering, correcting and
viewing. In addition, you can also view all transactions on
the account within a selected time frame, as well.
Anything you can view on screen is supported in the print
menu, too, But here is the second minor problem. The
program uses the faster clock speed of the CoCo 3 for
everything except disk I/O. This makes all functions run
very fast — including print. If you use the standard 600 baud
printer rate, the data will be coming out the serial port at
[200 baud (thanks to the speed-up poke). I spoke with
Darryl Hawkins, president of SECA, and he tells me there
is a version of the program in development that allow users
to select their own baud rate within the program. Here is
the fix to get the old version to run with your printer:
Insert PDKE150 ,„v.v at beginning of Line 230
(xx is the baud rate you use).
Insert PDKE6549S , 8 just before the RETURN statement
in lines 3400 and 3410.
Another nice thing about this program is that it makes
extensive use of the CoCo 3's new features — without trying
to squeeze an example of each into the program. The new
□N BRK GOTO function is utilized as the way out of any
selected function. The screen is a very pleasant white with
blue lettering, and features the inverse and blinking text
when telling you how to proceed. The two function keys
are used in various places to select options (most notably,
in the printer routines).
Normally, I don't like to suggest editing commercial
products. I will make an exception in this case. I feel that
the program has enough merit to justify the little bit of fine
tuning you need to do. I am also encouraged that Mr.
Hawkins has the program s author, B.J. Anderson, working
on improving an already excellent piece of work.
In short, if you are looking for a financial guru to make
you fabulously wealthy, keep looking. If you need a good
program to help you understand what the bank hath
wrought on your checkbook, and to help you keep track
of where that hard-earned paycheck goes, I don't think you
could do much better than this. The price and features make
this program a very good buy.

Spectrum DOS —
A Bag Full of Treats
for the CoCo
(This program was originally reviewed in the August J 984
issue of THE RAINBOW, but we're taking this ''second look"
for the benefit of new readers.)
There have been a number of attempts to add features
to the CoCo in the form of a modified or replaced operating
system. I tried a few of the earliest ones, but I always ended
up back with my own collection of programs and patches
to correct various deficiencies. With the possible exception
of a system or two where I have 10-Meg disks operating,
Spectrum DOS could supply all the things I feel were
lacking in the CoCo. These include a built-in Hi-Res screen,
error trapping, reset trapping, access to double-sided disks
and more tracks per disk. This is just the beginning of the
list of goodies offered.
Spectrum DOS has gone a long way beyond putting
together some of my early most desperate needs into one
package. How many times have you typed NEW and
immediately regretted it? Well, now there is Did, and you
have that destroyed program right back. How about those
several long lines of pokes that have the wrong line number
on them? No problem, Spectrum DOS will let you move
them to the correct line (LMove feature) or simply copy
them to another spot where they are needed (LCopy, which
is non-destructive).
There are many such programmer aids. For example,
PPeek and PPoke deal with the full, 16-bit value you
generally want to deal with in peeking and poking. FKey
lets you easily define keys as function keys. Auto generates
line numbers (giving you the choice of start number and
increment). Load will look on all disks for the program you
want. All keys repeat if held (a slight problem for my heavy-
handed keyboard approach). If you happen to interrupt a
program you are debugging and it is functioning in upper/
lowercase at the time, you can still enter commands in
lowercase, and the system will understand them. There's
nothing earthshaking about this feature, but it exemplifies
the fine thought put into this piece of software. Bob Colin
is certainly to be congratulated for a truly professional
product. It contains some features that I still find missing
in the high priced micros.
"True upper- and lowercase letters" is among the claims
that I did not find to be true. Perhaps there is a definition
problem here, but I used the Hi-Res option extensively,
which has options of 32, 51 and 64 for screen widths. They
work simply and are very readable (even the 64 width that
I used most of the time), but the letters such as 4 p' and 'q'
do not go below the line, which is my definition of "true
lowercase." The quality and spacing is good, so I could
certainly compromise on this deficiency to gain all the other
goodies in the package. There is even a Memo feature, which
permits you to write a one page memo and then dump it
to the printer. It uses the four arrow keys for editing your
text (though there apparently is no delete function). I was
disappointed that I could not get this Memo feature to work
in conjunction with Hi-Res 64, since this would permit a
much longer memo, but nevertheless, I found it an
interesting and useful system feature.
The documentation is a simple six-page manual that is
well-written and well-organized. The system features work
so simply, and the system installs so easily that long
explanations are not necessary. The system can be used by
many as it is delivered, but the install program lets you
modify parameters to fit your system (number of disks, disk
types, prompt character, printer speed, cursor type, etc.).
Defaults are taken simply by pressing the return key, and
the whole install should not take much over a minute.
Spectrum DOS can also be burned into a regular
EPROM after customizing it to your setup, but do get a
128K EPROM, or you will lose Hi-Res Help and Flex —
two features you would not want to lose.
Best of all, it works! I have by no means exhausted the
list of all the features, but I think I did try most everything,
and I found no bugs, nor even spots, where I wasn't quite
sure what to do next. Spectrum DOS is well-protected from
accidental blowout. I did manage to load a program of mine
that had its own On Error system poked into memory, and
that sure did some strange things to the Inverse screen and
Normal functions, but one can hardly fault the Spectrum
DOS operating system when you start poking code
randomly into memory. I used the system with a rather large
word processing program of my own design, and it worked
fine, so little or no memory is consumed and operational
speed is not sacrificed to any degree that I could notice.
1 love computer power with simplicity. That's what
brought me to CoCo in the first place, even though I have
been a professional in the computer field for more than 25
years and worked on many multi-million dollar machines.
Spectrum DOS carries on the CoCo tradition in fine style,
with value, power and simplicity.

Hint . . .
Put 'Call Waiting' on Hold
If you have a modem and have call waiting on your
telephone line, there is a good chance you have been
bumped offline by an incoming phone call. (Actually,
the problem is not the tone you hear to announce the
call, but during the tone the connection is broken
momentarily.)
In many areas, you can temporarily disable call
waiting by dialing 1170 (or *70 if you have tone
dialing), waiting for the dial tone to return, then
dialing the number just as you normally would. When
you hang up, call waiting is restored, so you will need
to dial 1 170 (*70) before every modem call.
If you get a recording instead of a dial tone, this
usually means the switching office serving your area
hasn't been upgraded to add the disable feature. Check
with the phone company to make sure your call
waiting is actually working. If it is, find out when
"equal access" long distance service starts because the
change will usually be made at that time.

Professional Mailing Labels
With Multi-label III
If you are responsible for your church, club or business
mailing list, you will find Multi-label III a valuable tool.
It stores your mailing lists and prints them in one of 1 3 styles
you select. You can mail notices, bills, and correspondence
with business-like labels using your CoCo and printer.
We've all been looking for programs for our shiny new
CoCo 3 computers, and Multi-label III is a good example
of what to expect. It uses the super colors, speed and error-
trapping commands to provide a very well put together
program. Written in BASIC, it requires a CoCo 3, single disk
drive (or multiple), and a printer. It is user-friendly and
foolproof, as far as I could tell.
The specific CoCo 3 features built into this program
include either a 40-by-24, or 80-by-24 high resolution
screen. It uses the Fi key as an upper/ lowercase toggle and
the F2 key to toggle between the screens. Multi-label III uses
the ON ERROR GOTO command to trap errors such as DISK
I'D and FILE NOT FOUND preventing program crashing. It
also uses the ON BREAK GOTO command to return to its main
menu should the BREAK key be pressed. The program uses
the CoCo 3 high speed poke and escape poke to provide
high speed operation.
Multi-label III is supplied with the PALETTE command
for an RGB monitor. However, the manual provides three
simple editing changes to convert it for a composite monitor
or TV. Using a TV, I was very impressed with the colors
but, as with otherCoCo 3 programs, some were faded, and
some screen instructions difficult to read.
This did not seriously detract from the program; however,
I think programmers should select colors with an eye on
TV and composite monitor users, as well as those with RGB
equipment. A little experimentation with my color control
helped, too,
The program worked perfectly for me on my first attempt.
I was able to input, store and print labels easily. Multi-label
///requires the use of the standard V/i- by 15 /i6-inch, single-
column, gummed labels, readily available at computer
stores. The print menu provides 13 combinations of
printing, including Elite, Pica, Italic, Expanded,
Condensed, Double Strike and Emphasized. The manual
lists the printer codes used, and it would be easy to change
the codes in the program to fit any printer or to select other
combinations.
The menu provides 1 1 choices that involve entering
information, editing, saving to disk, loading, printing and
reading the files saved. It also has a Help command that
explains each menu command. The User's Manual is well-
written, complete and easily understood.
In summary, Multi-label III is a very useful program for
producing professional mailing labels. It takes advantage
of the best features of the CoCo 3 to provide speed, error-
trapping, and beautiful high resolution screens.

A Guide to CoCo 3
Basics and Graphics
Now that the CoCo 3 is here, we ail find ourselves
wondering how to best use its expanded graphics features.
A Guide to Co Co 3 Basics and Graphics is a 54-page booklet
and disk for the graphics enthusiast. As powerful as the
CoCo 3 is, many of you have no doubt been dismayed at
the lack of information contained in Tandy's manual. Color
Computer 3 Extended BASIC, that comes with each
machine, This recent offering by Linda Nielson goes into
the depth and detail that Tandy didn't coven If you are
serious about graphics on the CoCo 3, you will find useful
information in this package. The book is written in a
friendly and understandable manner and is sprinkled with
programming aids and tips. Lots of sample programs are
included in the book and on the disk that are used to
demonstrate the various subjects discussed. An early
chapter deals with a novel approach to understanding how
the CoCo 3 uses 5 1 2K of RAM with its Memory M anage-
ment Unit, Other detailed discussions are provided on the
following;
Faster clock speeds
Built-in error trapping and error codes
FUNCTION, ALTERNATE and CONTROL keys
Button function
Added colors and commands including artifacting
Monochrome displays
Palette command
High and low resolution text screens
High and low resolution graphics
Graphics editing
Patterns and shading
One noteworthy program on the disk is called Drawback
and is quite powerful. With it you can draw lines, circles,
rectangles, enter text, paint and stamp areas with images
picked from the screen. A demo picture showing a man
holding a hawk is one of the best CoCo 3 images I've seen
and can be used with Drawback to develop your graphics
editing skills. Other programs on the disk are used to
illustrate color codes, palette slots and artifacting.
I believe that this book and disk are worthy of your
consideration if you are Into graphics programming. If
graphics is not your bag, I suggest you look elsewhere for
CoCo 3 programs. All of the information in this package
is supportive in nature and is meant to be a tutorial on
capitalizing on the CoCo 3's graphics potential.

THE RAINBOW July 1987
Software Review J * w mm^ ^
Checkerboard r lie sort —
Meireshing Change
When 1 received Checkerboard Filesort to review, I
thought it was just another filesort program! But when 1
sat down and started going through the instruction manual,
1 got very interested in the program.
As the developer states in his introduction, this program
can only be used with a cassette-based system. 1 have to say
that this was a refreshing change because so much of today's
software is for disk systems and, in increasing numbers, for
the CoCo 3, Sometimes it seems as if those of us with
cassette-based systems are rapidly becoming orphans,
Checkerboard Filesort was written for a 32K or 64K
cassette-based CoCo. 1 was really impressed by all of the
different options that are included in the program. Machine
language routines handle record entry, editing, reviewing,
search and sorting. You can number records from one to
9,999; in this way, you can append (join together) different
records.
You can have a minimum of 40 records, each containing
240 characters, or a maximum of 200 records containing
42 characters in the 32K version. In the 64K version, you
can have a minimum of 86 records, containing 240
characters, or a maximum of 400 records that contain 46
characters. You can use this program to keep an address file,
mailing lists, inventories, recipes, etc. The only constraint
to what you can do is that you have a limit of 240 characters
per record.
You also have the option of using a printer to get a hard
copy of your records. Although this program was written
for use with an 80-column printer, 1 have been using my
D MP- 105, which is a 32-column printer, with no problems
at all. 1 called Dave Siebold, the program developer, to see
if 1 would have to change any of the printer codes. He was
very helpful, and sent me all the information that 1 needed.
Dave also told me that if anyone wanted to purchase the
program, and they are not using the Radio Shack printer,
he will make the needed modifications to the program at
no additional charge.
After loading Checkerboard Filesort^ you are prompted
to enter the printer codes. If you are not using a printer,
you can enter any number for each prompt. After the printer
codes are entered, the main menu appears. You can choose
one of the following options:
1) Create file
2) Edit record data
3) Add/ Delete record
4) Search/ Review records
5) Hard copy options
6) File tape load/ append
7) Save to tape
8) Display/ Rename fields
9) End program
The first option allows you to create your files. The
second allows you to edit any of the records you have
created. You do this by entering the number of the record
you want to edit or, if you don't know the number, you have
the option of using the search routine to find a particular
record, You can also use the review section to find the record
and then edit it. The third option allows you to add or delete
records.
The fourth section allows you to review all records, a
single record, or a group of records, The second part of this
option allows you to search for a particular record using
partial data or a set of records that contain similar data.
The fifth section allows you to choose many different
ways to get a hard copy of your records. You can have them
displayed in one of the following ways:
1) Single column
2) Two columns
3) Three columns (can only be used with the condensed
=> 16.7 cpi)
4) Mailing labels
5) Envelope labeler
The sixth section allows you to load or append a file from
cassette. The seventh option allows you to save a file to tape.
After the file is saved, you are prompted to verify the save.
The eighth option allows you to display or rename the fields.
The fields are used for your information and are not
displayed while you are creating a record. The ninth option
allows you to end the program. If you choose to end the
program, you will be returned to the normal power-up
configuration. The instruction manual included with the
program is very well-written and provides an in-depth
discussion of each of the above options.
There is a BASIC program called Convert that follows the
machine language portion of this program. The program
is used to convert Filesort programs to a format that is
acceptable to most word processors. So you can convert a
file and then load it into your word processor. 1 have Color
Scripset on a ROM pack, and 1 tried the convert program.
1 had no trouble loading the converted file into the program.
After using this program on numerous occasions, 1 am
impressed by the program and its ease of operations, It is
completely menu-driven and user-friendly. The options that
are included make it very nice to have around. I especially
like all of the hard-copy options.
1 have been very happy in my dealing with Dave, and 1
would not hesitate to buy Checkerboard Filesort from him.

Software Review,
Discover the Benefits of
ADOS-3
By Dale Shell
WeJi, it is finally here. ADOS-3 — for all of you who have
a new CoCo 3 and really miss all the enhancements of
ADOS that you grew so used to and thought you could
never do without. The best news is that ADOS-3 really is
more than just a modified version of the original ADOS.
It offers a lot more enhancements.
Of course, the bad news is that since ADOS-3 is almost
a new program, and it is bigger and better, it is not offered
as an upgrade to current ADOS owners. It must be
purchased separately. However, I do think that when you
get it, you will not be disappointed that you put out the
money, It adds so much to the CoCo 3 that I cannot imagine
the CoCo 3 without ADOS-3; it would not be a complete
machine.
There are so many good things about it, I am not sure
where to start. Since versions of ADOS have been reviewed
in two previous issues of RAINBOW (December 1984 and

P.O. Box 65905 Visa/Mastercard
Los Angeles, CA 90065 M.O.
June 1 987), I will not cover in detail every enhancement the
new ADOS-3 adds to the Radio Shack DOS. I will,
however, list some of the features of the original ADOS that
are still supported, just in case someone out there is not
familiar with ADOS.
These features include repeat and edit of the last direct-
mode command; CONTROL key abbreviated entry of BASIC
commands; automatic line-number prompts; upper- or
lowercase command entry; DOS command for OS-9; one-
or two-column directory with free granules (to screen or
printer); COPY filename TD drive number alternate form of
COPY command; AE Error ("file already exists") override
option; RUNM command to load and execute machine
language programs; SCAN command, which will list ASCII
files to the screen or printer and give the start, end and
execute addresses for binary files; PRT ON/OFF to enable/
disable routing text output to printer as well as screen; M0N,
a mini-monitor command that provides hexadecimal
memory examine-and-change capability; the ability to use
35- or 40-track, single- or double-sided drives; and the
option to change the start-up logo, instead of seeing the
familiar Radio Shack logo come up every time you turn on
your CoCo, you can have whatever message you want
(limited to 63 characters). This is a good place to put your
name for a type of theft protection.
All these features are great just as they are, but ADOS-
3 adds even more and improves on a few of these. First of
all, two new commands, FAST and SLOW, have been added.
These two commands control the processor speed. FR5T sets
the processor speed to the double-speed (1.8 MHz) mode.
Of course SLOW sets the speed back to the .9 MHz mode.
You must be aware that while these two commands
automatically adjust the printer baud rate constant to take
into account the processor speed, this may cause a problem
if you have a program that changes the baud rate constant.
This was the case while I was using VIP Writer. I always
set the baud rate to 7, which is 9600 baud. My printer went
bonkers. I had to set baud to 6 (4800 baud) so at the FR5T
speed, it would print at 9600 baud. This can definitely be
a concern with communications software.
The safest thing to do if you start to have problems is
to go to the SLOW mode, see if things work normally and
proceed from there. This is no big concern if you are aware
of the possible symptoms and remember to enter the SLOW
command, adjust the program accordingly or just enter a
line in the BASIC loader that contains the SLOW command.
[ had no problems with disk I/O using the FAST mode.
ADOS-3 adds some very powerful editing features. When
a BASIC program is in memory, the up and down arrow keys
can list the program forward and backward, a line at a time.
If held down, these keys will repeat. This is a very convenient
way of controlling the scrolling of the program, especially
when you are editing a program. Once you have listed the
line you want to edit, you simply press the right arrow key.
This puts you in the edit mode and you may edit the line
as usual. This also becomes a very powerful debugging
feature if you get dumped out of a basic program by an
error; pressing the right arrow puts you in the edit mode
for the line that caused the error.
The slash command (/), which repeats the last direct-
mode command, has also been modified. It will allow you
to list a line of BASIC code and edit even the line numbers.
This is good for copying lines of code to other parts of the
BASIC program.
138 THE RAINBOW July 1987
If you use a monochrome monitor, you will be very
interested in ADOS-3's option to kill the colorburst signal.
Pressing CTRL-F2 while in the direct mode kills the
colorburst signal, resulting in a monochrome display if you
are using a composite or TV output, This greatly enhances
the signal if you are using a monochrome monitor.
When you start to customize ADOS-3 to be burned into
an EPROM, there are many options you can include. While
ADOS-3 will run as a disk utility, to get the full benefit from
ADOS-3, you need to eventually get it into an EPROM.
One of the options that can be selected when customizing
ADOS-3 is the default screen display. ADOS-3 allows the
equivalent of a WIDTH command, a PALETTE RGB command,
four PALETTE color assignment commands and an ATTR
command to be selected for automatic execution when the
computer is turned on or on any cold start.
The default borders for the 32-, 40- or 80-column screens
can also be configured, so you can have the default screen
be just about any color or width you desire. Even the 32-
column screen uses real lowercase letters rather than the old
inverse characters, Once these are in the EPROM, the
screen setup, with the exception of WIDTH, will also be re-
established on a warm reset. The documentation gives some
good tips on setting up the screen display the way you like
it.
When you are finished with the screen, you can decide
at what speed you want the processor to run when the
computer is turned on. This will allow you to have the
equivalent of a FAST command executed on a cold start.
Also configured in the customizing is the repeat rate of the
up and down arrow keys. The up and down arrow keys are
also used to control the display when using the MON
command.
While the original ADOS allowed you to have 35- or 40-
track drives, ADOS-3 adds the option of having 80-track
drives. All 1 58 granules of an 80-track drive are usable under
the 80-track option, ADOS demands that all drives be
configured to the same number of tracks. You may have a
40-track drive connected to a system configured for 80
tracks, but be careful not to try to access any nonexistent
tracks.
ADOS-3 has also redefined which key will be used to clear
the screen. F2 is used instead of the clear key because many
users accustomed to the CoCo 1 or 2 keyboard might find
themselves clearing the screen when they intended to hit the
backspace key. F2 is also used instead of the very awkward
,SHlFT-up arrow for exiting the insert mode when line
editing. Both of these redefinitions are optional and can be
configured back to the original use if desired.
If you are like some people I know, you only read the
last paragraph of a review. So, the bottom line is: If you
have a CoCo 3, go out immediately and buy ADOS-3 for
your CoCo; your CoCo will not be complete without it. If
you have a CoCo J or 2 and will be getting a CoCo 3 in
the near future, ADOS-3 will work in your controller now
You just won't have access to all its benefits until your CoCo
3 arrives. On a scale of I to 10, I rate ADOS-3 a solid 15.
Buy it; you and your CoCo 3 need it.

Software Review ^ ^^^ ^^^^^m
Ultra Editor — A Timesaver
for Programmers
Ultra Editor is the first Color Computer 3 program
written by Bob van der Poel and is certain to be a hit with
his followers. Bob consistently turns out excellent software
for the CoCo, and his latest effort is no exception.
Ultra Editor is a full-featured, 40- or 80-column screen
line editor. It's designed to edit lines of text such as basic,
assembly language and pascal programs. It incorporates
a host of commands that allow virtually any manipulation
and modification to any program or word processor file.
Its main purpose is not for use as a word processor, but
the editing features are similar and the program is handy
for editing such files if needed.
The software is supplied on disk, but the I/O can be
modified to use with cassette. The disk contains a short
IAS1C loader, but the main program is written in 6809
machine language. Documentation is ample. Sixteen pages
are packed with explanations of the many commands.
This is the kind of software that will please programmers
since it provides many valuable, timesaving methods to edit
programs.
Full cursor movement is available using the arrow keys.
Rapid movement from beginning to end of file is provided
with the ALT key and a combination of either the or Y
keys. Using the ALT key in combination with other keys
provides some very powerful editing commands such as
Find, Jump, Change, Global Change, Kill Line, Unkill
Line, Hack Line, Yank Character, Backspace and Insert.
You can also insert or delete blocks, move blocks, copy
blocks and transfer blocks. An excellent feature is that Ultra
Editor maintains two separate buffers. The main buffer is
approximately 5 OK bytes long, while the second one is
about 16K bytes long. Using the Transfer command allows
data to be transferred between the buffers. Macro com-
mands are also supported. These are great timesaving
commands that can be set up to duplicate any sequence of
keystrokes that you desire. The only limitation is that the
macros cannot exceed 49 characters, and no more than nine
macros are available. They can be saved as part of the
program that you are editing so you can have different
macros for different situations.
Onscreen help is also available at the tap of a key, H itting
Fi d isplays multiple pages of the various commands
available so you won't have to thumb through the docu-
mentation if you forgot how to do something.
This program is very well done, and I am convinced that
it offers the software hacker some real opportunities. Many
hints, tips and examples are used thoughout the documen-
tation to help the user understand the concepts presented.
It's not difficult to use and, while a bit sophisticated in terms
of what it does, it is not a program that novice programmers
would want or need. But as programming skills are
sharpened and programs become more complex, Ultra
Editor will become a well-used utility.

Disk Manager Helps
Control and Modify Files
Looking for a program that will help you manage your
CoCo 3 disks? Look no more — Disk Manager will come
to your rescue! The functions this BASIC program provides
are plentiful and just what I needed to help control my CoCo
3 disk directories. I use it primarily for my TCBBS Bulletin
Board disks, but you can use it for any application of your
own.
The program requires a 128K CoCo 3 (it is written
specifically for this machine and will not work on a CoCo
1 or 2). A choice of using either the 40- or 80-column
character screens is provided. A 32-column screen is not
supported, so a monitor may be necessary in order to see
the full screen (most TVs will cut off the first couple of
characters on the left side of the screen). Colors are used
and can be changed from within the program, although it
is rather confusing to figure out how to modify the code
if you're not familiar with the new Enhanced Extended
BASIC commands.
Several different commands are available. Files can be
copied, killed, moved or renamed. These functions can be
done with individual files or by groups of them. One can
also print directories or sort them. Options to turn the verify
on and off are also provided. Complete documentation is
provided with the package and explains all the different
commands in detail.
One disadvantage with this program is that you must have
the documentation in front of you, since there aren't any
menus. The time it takes to look through the documentation
is frustrating. But in the long run, you'll eventually
memorize most of the functions, since the small abbrevi-
ations coincide with the function you want to perform (e.g.,
4 C stands for Copy).
This is a nice utility, and I recommend it to anyone
wanting to quickly modify their files without having to type
in the full BASIC commands that would otherwise be
required.

Dress Up Programs and
Design Title Screens
With Title
Title is a program written in BASIC that helps program
authors design title screens without spending large amounts
of time figuring out how to make them. Once the title screen
is drawn, Title creates a subroutine that can be merged with
a BASIC program in order to recreate the title screen just
drawn. A simple GOSUB will recreate the title screen, and
multiple title screens may be included in a BASIC program
subject only to memory restrictions.
Title is supplied in unprotected form on disk, and the user
is cautioned to operate from a backup of the disk at all
times. Title is available for 32K disk-based Color Comput-
ers, including a version for the CoCo 3.
The Title characters are four lines high by three spaces
wide. Any printable character entered from the keyboard
may be used in the title screen, except for the lowercase
alphabet. A full screen of characters requires about six
minutes to process into a subroutine.
Foreground and background colors are available, but are
limited to the capabilities of the low resolution text screen.
Letters may be green, yellow, blue, red, buff, cyan, magenta,
or orange on a black background, as well as black letters
on each of these background colors in turn.
The documentation for Title deserves some comment.
The documentation is in the form of a4-by-5 booklet and
is printed in elite type. The author also wrote the program
(called Book) that produced the documentation. I found
this format to be an interesting and novel approach to
documenting.
I found Title to be a well-behaved utility program and
one that can be of use to program authors or those who
simply want to "dress up" their programs a bit. The price
may be considered a bit high by some for a BASIC utility
program, but Title works well and has no quirks in
operation.

Backup and Backup III
Lots of Promise
I received my first original CoCo utility, and it has a lot
of promise. I unwrapped the package from BrainChild
Software and actually found two products, Backup and
Backup III, Backup is for CoCo Is and 2s, and Backup III
takes advantage of the 128K of the CoCo 3.
As you can tell from the name, these are backup utilities.
But unlike Disk BASIC, which only copies five tracks at a
time, Backup copies 10 and Backup ///copies 19 tracks at
a time. This cuts disk swaps from seven (eight if 40 tracks)
down to four and two. Another advantage is that if an
I/O Error is encountered, the procedure is not aborted as
in Disk BASIC but, instead, the tracks, sector numbers and
errors encountered are reported onscreen. This allows you
to salvage data from disks that have bad sectors. The error
messages are displayed on the bottom half of the screen in
the following format:
0214 DRIVE NOT RERDV
The first two digits designate the track number, and the last
two represent the sector. You can note these and work on
restoring the data in these sectors later with another utility.
Both Backup programs support 35-, 36-, 40- and 80-track
drives. The documentation goes even further and states that
if you have really non-standard drives, you can select any
number between one and 99 for the number of tracks. The
Backup programs also perform a much faster verify than
Disk Basic's. All this sounds really good, but I would like
to see a modification. I only have one big complaint. While
the Backups reduce the number of disk swaps, 1 normally
use a two-drive backup. Therefore, I do not do any "disk
swaps."! would liketoseeanoptionaddedthatwould allow
a two-drive backup. It seems it would be easy to add to the
programs.
Along with the main backup utility on each disk, a utility
named ZRP . BR5 is also included on the disk. This program,
Zap, can be used to copy single sectors from one disk to
another. You are prompted to enter the track and sector.
Enter it in the same format as the errors are reported in
either Backup or Backup III, e.g., 0214. This program can
help salvage data from a disk with bad sectors. While it will
not help on some really bad sectors, successive attempts on
some sectors may result in restored data.
Overall, I believe Backup and Backup III are useful
utilities. For the price, they are very reasonable. While I
would really like to see an option for multiple drive backups,
these utilities will be extremely useful for those who only
have one disk drive.

RGB Patch Brings PMODE4
to Life on CoCo 3
From what I gather, a lot of CoCo 3 users are having
somewhat mixed emotions about the switch to analog RGB
output; it's very nice and a worthwhile improvement, but
the many programs that use PM0DE4 artifact colors just
display gray lines instead of red and blue. There are several
ways around this; one is to use a color TV set, tuned to
channel 3 or 4, to receive the CoCo RF output, while
another is to buy a monitor that has both RGB and
composite inputs. Both of these are hardware approaches
and work reasonably well, but some are no doubt looking
for a software patch.
RGB Patch is a short machine language routine that loads
from disk into the CoCo 3, tucks itself away and stands by,
almost invisibly, to do its work when called upon. When
a machine language program switches the system to PMDDE4
with a black/ buff screen (the mode used for artifact colors),
RGB Patch re-switches the CoCo 3 to its 320-by-200 Hi-
Res screen instead. As the program writes to the PMDDE4
screen, RGB Patch updates the 320-by-200 screen by
checking where the dots are, analyzing the dot patterns to
determine what color they are — in effect approximating
the NTSC color decoding process — and then putting the
corresponding dots on the 320-by-200 screen in the proper
colors. The color quality is quite good. The results 1 saw
were sharper and clearer than composite displays. I was
initially afraid that RGB Patch would mis-identify some
white areas as color, as do some boards that are used to
display Apple II graphics on RGB monitors. I didn't see
any trace of this effect. RGB Patch apparently is able to
determine white with some degree of intelligence, perform-
ing a task somewhat akin to that of the comb filters used
to separate color and luminance in the better color TV sets.
RGB Patch is said to be compatible with 90 percent of
the ML programs that need it, but is not compatible with
BASIC programs, OS-9 or with ROM packs. I don't have
any way to tell if that percentage is accurate without testing
a lot of programs, but the first two programs I tried did
not work; one gave no color and the second never got past
the color test screen, possibly because of an incompatibility
with the CoCo 3. Once I got a program that did run in color,
all was well.
As for those color test screens, it should be noted that
RGB Patch does not have a normal method of switching
the red and blue artifacts to conform with different
programs. If, however, you find that the colors are wrong,
you can poke in new palette values for "red" and "blue" to
fix it; you can also change them, and "black" and "white"
as well, to whatever CoCo 3 colors you desire.
If you have an RGB monitor, and want PM0DE4 colors,
RGB Patch just might be the best way to get them.

HI-RES HI was designed to improve the standard display capabilities
of the Color Computer 3, even the 40 and 80 column displays have
several features missing. For example you can't use PRINT © or
have different character sizes on the same screen, even mixing
text and graphics with the HPRINT command leaves a lot to be
desired. HI-RES 111 can give you the kind of display capabilities you
always dreamed about having on your color computer but didn't get
with your COCO-3. Weil now it's here and with a wide variety of
display options that you can easily use with your Basic or ML
programs. HI-RES III is totally compatible with Enhanced Color
Basic and its operation is invisible to Basic. It simply replaces the
normal screen display with an extremely versatile display package.
It also overcomes some of the disadvantages found when using the
Width 40 £* 80 screens. You can use the Print © function on any
line length with Hl-RES III, it also gives you a programmable
automatic key repeat that can be very handy for editing your Basic
programs. Automatic key repeat can be adjusted from ultra fast ti
super slow and can be disabled entirely if desired. You also get a
full control code keyboard using the "CTRL' key. So many of HI-RES
Ill's extended functions can be controlled directly from the keyboard
easily. With just a couple of simple keystrokes you can change
character sizes and styles at any time. You can even switch back
and f »rth botwoon the standard COCO-3 display and MI-RES IH with a
simple keyboard entry or under program control. But, after you
use HI-RES III, you most likely won! want to do without it again.
HI-RES III can be used for a wide variety of applications, with its
many different character sizes and styles. You can make your
program really look professional, wttn protected menus, Doid or
italic emphasis. Double or Quad characters for easy to read displays
&. menus. It can be idealy suited for Video Titles or Store Displays.
Printing Signs or Fliers in conjunction with a Hi-res Screen dump
program. The visually impared will espically appreciate the extra
large character sizes available.

COCO 3 DRIVES J & M Systems, Ltd. has
introduced its 3/2-inch floppy drive subsystem for
the Color Computer 3. The user-installable
subsystems are available in two basic configura-
tions. An external, stand-alone model with case,
power supply and cable is available for $250.
Users wanting to add a drive to their current case/
power supply unit can purchase a 3 J /4-i nch drive
mounted on an adapter bracket, which will fit in
place of a 5^-inch floppy, for $199.
Both subsystems are 80-track units with 720K
formatted capacity under OS-9 Level II. The
drives may be used with Disk Extended Color
BASIC and will yield I60K capacity. For addi-
tional information and details, contact J & M
Systems, Ltd., 15 / 00 A Central S.E., Albu-
querque, NM 87123, (505)292-4182.
uP DEVELOPMENT SYSTEM The P68000
uLAB microprocessor development system with
an educational price of $197.50 has just been
announced by University Research and Develop-
ment Associates, Inc. (URDA, Inc.) and is being
manufactured by Quasitronics, Inc. The P68000
uLAB is a 68000 microprocessor and support
chips with keypad, LED display, 4K bytes
SRAM, 8K bytes of EPROM, cassette interface,
software operating system, power supply, User's
Manual and Programmer's Reference Manual
completely packaged in a three-ring binder, i.e.,
a Notebook Computer.
The uLAB is engineered to be low cost, provid-
ing a complete microprocessor development
system for hands-on experience for engineers,
technicians and students. Because of its size, the
uLAB can be carried to the home, dormitory, or
other work or study location for experimentation
at the user's convenience. It is also suitable for use
in conjunction with lecture-type courses.
The uLAB comes complete with a listing of the
software monitor, including comments and
documentation, and a schematic including every

GROUND COVERAGE Pilgrim Electric Com-
pany has announced a new grounding device for
antistatic equipment. The Model GAM-1 Smart
Static Ground Monitor provides two Fail-Safe
discharge ports and monitors the quality of the
building ground.
When the GAM-I is plugged into a standard
1 5- or 20-amp 1 20 VAC receptacle, it continuously
checks the outlet circuit wiring and its Go-No-Go
light turns on if the outlet is correctly wired and
the building ground is adequate for draining static
charges.
The new GA M- 1 provides two "Fail-Safe" ESD
ground connections, a standard Banana Jack and
an Apple Jack. The Banana Jack accepts a
standard banana plug. The Apple Jack accepts a
stranded or solid wire of 18 to 22 gauge, and
alligator clip adapter, a ring terminal, fork lug or
quick disconnect — without using tools. Its quick
insertion and retention method facilitates wiring
and maintains electrical contact integrity. Both
jacks have integral I -megohm current limiting
resistors to safeguard users from shock hazard.
The GAM-I carries a list price of $24.95. F#r
more informati0n, contact Pilgrim Electric
C0mpany, 105 New/own Road, Plainvirw, NY
11803.

The GAM -J offers fml-safe monitoring of your
building's ground connection.
LOOPHOLES IN COMPUTER FRAUD ACT
Computer crime is not a youthful prank by
teenage "hackers," as it is often portrayed in
movies. Each year, economic losses due to
computer crime are estimated in the multimillion
dollar range. Many of those losses go undetected
or unreported.
The recently enacted Computer Fraud and
Abuse Act of 1986 remedies many of the short-
comings of a previous bill passed in 1984. But,
some of the earlier bill's deficiencies remain
uncorrected, and the new statute adds difficulties
in criminal prosecution, according to an article in
the current issue of Criminal Justice, published by
the American Bar Association's Criminal Justice
Section.
Some important terms, particularly "access,"
"use," "affects" and "without authorization,"
remain undefined bythenewlaw, according to the
authors of the article, Joseph B. Tompkins, Jr. and
Federick S. Ansell.
Under the new law, even if someone accesses
a financial institution's computer without author-
ization, no crime is committed unless he obtains
information or causes damage totaling $1,000.
Additionally, the statute concerns only crimes
against data, but does not protect software.
Tompkins and Ansell call for increased prose-
cution of computer crimes. Although many
computer owners are reluctant to report crime —
banks, for instance, may not want their depositors
to know that their institution is vulnerable —
everyone would be better off if computer crime
were prosecuted, both to obtain restitution for
victims and to deter future criminal activity.

Hint .
I Screen, You Screen
The PfiLETTE command is used to easily change the
colors of the screen you are working on. The following
table indicates the slots used for various screen
parameters.
Mode
32-column
40/80-column
Foreground Background
Slot Slot
Slot 12
SlotO
Slot 13
Slot 8
As an example, in the 32-column mode,
PfiLETTE12,63:PfiLETTE13,0 will give white letters
on a black background. In the 40- or 80-column mode,
Pfil_ETTE0,0 :PflLETTEB , 63 : CLS1 will accomplish
the same thing. Note that the CLS1 is used to make
the border color the same as the background.

Hint
Neat Little Modification
The following is intended mostly for those who have
some experience in hardware alterations. You can
easily mount a DB-25 connector on the side of your
CoCo and hook it to the existing keyboard connec-
tions on the bottom of the board. Then take an old
CoCo keyboard (or buy a new one) and an old CoCo
case (or build your own) and make a stand-alone
keyboard. Just wire the keyboard to a DB-25 connec-
tor that will mate with the one mounted on the CoCo.
Nine of the conductors on a 25-conductor cable are
not needed. However, they open up the possibility for
remote reset, power-on indicator, etc. Once you have
worked out the particulars and constructed your
remote keyboard, move the CoCo and Multi-Pak
Interface and other accessories off your desk. You will
be surprised at the neat appearance this little modi-
fication offers.

Graphics Experience
You Can Draw From
By Joseph Kolar
Rainbow Contributing Editor
The purpose of this and next
month's tutorial is to teach the
newcomer how to correct or
modify a lengthy DRAW statement that
may contain up to the maximum al-
lowed number of characters.
Why bother? One of the chief obsta-
cles that frustrates CoConauts is that a
well-stuffed DRAW statement is complex
and confusing. After creating a picture/
display and finding an error or wanting
to alter the drawing, the newcomer is at
a loss. He has difficulty identifying the
offending portion of the program line.
He is leery of making corrections that
may destroy or distort his masterpiece.
This can be a baffling problem. In order
to make corrections and changes, we
shall first draw a stylized head. (See
Figure 1.)
A picture was drawn on graph paper.
Each corner of a square is equal to one
unit from an adjacent corner or neigh-
boring intersection. The picture is
drawn in pencil. Then the straight-line
segments are guided to the nearest
intersection. Dots are placed at these
intersections and straight lines are
drawn connecting the dots. (Think of a
child's "connect the dots" puzzle.) After
all the lines in the drawing are con-
nected, go over them in some color, say
red. The end points of every straight line

ducing beginners to
ihe powers of the
Color Computer.
segment are tick-marked in a contrast-
ing color (black).
Figure 1 is ready to be reproduced on
CoCo's screen. This drawing looks
fairly neat, but when itis translated into
DRAW statements and viewed on the
screen, it may look distorted.
One reason is that the 256-by- 1 92 Hi-
Res screen squares are not true squares.
The horizontal lines are shorter than the
vertical ones. To verify this, type:
10 PMDDE4,1:PCLS:SCREEN1,0
20 DRAWS16U10R10D10L10"
100 GOTO 100
Now run. With a ruler, measure each
side of the square.
Another reason the picture may not
translate well from graph paper to the
screen is that the drawing may be
sloppily created and not follow the
intended lines closely. CoCo pinpoints
and locates every instruction exactly,
without distracting deviations.
BM12B,9GU10 makes a straight line
from 128,96 to 128,86. You get what you
ordered in the DRAW statement. Nothing
freehand here!
Study Figure 1. Where to begin? At
any convenient point that suits your
fancy. You might choose to start at the
left shoulder, then follow the hairline
above the right eye, working around the
head to the other side and then skipping
up to finish the hairlines. You could
begin at an eye and do all the facial
features; start at the neck and do one
side or the other of the shirt. You could
do one side of the jaw line and work
around to the other side.
Truly, you can begin anywhere and
go in any direction, skipping and back-
tracking at will. This being the case, you
can easily understand why, since each
programmer has his druthers, it is
difficult to follow his train of thought
as he programs his DRAW lines. You can
easily get lost and throw up your hands
in disgust. To keep you off balance, I am
not going to tell you where I am begin-
ning the drawing and in what direction
I am traveling.
Look at the right shoulder. You will
see a line that moves three boxes to the
right and one box up. If you started at
the second point, the line would go three
Figure 1
boxes to the left and one box down. It
is all howyou look at it and where your
starting point is.
In the DRAW statement, this particular
line segment can be drawn using M, plus
or minus a numeral, and a comma (,),
plus or minus a second numeral.
Rule: From the starting point, a move
July 1987 THE RAINBOW 157
to the right or down is plus. A move up
or to the left is minus. The first value
must be the one that indicates motion
to either the left or right separated by
a comma; the second value will reflect
whether or not it moves up or down.
Type NEW and key in SQUARE if you
need to get an overview of the M option.
Otherwise, continue with this tutorial.
Beginning at the right shoulder (Fig-
ure 1), we move three spaces to the right
(+3) and one space up (-1). The move-
ment would be interpreted by CoCo as
M+3,-1. If you started at the second
point and moved the line to the first
point, the line would go three spaces to
the left (-3) and one space down (+ 1) or
M-3, + 1. You may omit the + from the
second value. To see your handiwork,
type NEW.
Rekey lines JO and 100. Type 20
DRAW"516M+3,-l" and run. From the
last end point, you now move three
spaces f urther to the right and one space
down. This translates to M+3,1. Insert
it in front of the closing quote and run.
You have the raw material for a zigzag
line.
Add Line 15 and rekey Line 20:
15 A$="M+3,-lM+3,l"
20 DRAW"SB"+A$+A$+A$
Now run it. We placed our zigzag into
a string and assigned it the variable, A$.
Now it looks like a wave. To make a
long wave and avoid the bother of
tacking on all those +A$s, type:
16 B$=A$+A$+A$
20 DRAW"SBBM2,96"+B$+B$
and run.
Out of String Space Error! Correct
by reserving adequate space: 5 CLEAR
500, then run.
You can concatenate up to seven +B$s
before CoCo gets upset and protests
with an LS Error. If we get an LS Error,
simply knock off enough +B$s so the
line functions and put them into a fresh
DRAW statement.
21 DRAWB$+B$
Check Line 20 to make sure you have
seven +B$s, then run.
To make an attractive chain add:
1? C$="M+3, lM+3,-1 "
IB D$=C$+C$+C$
and rekey Line 21 :
21 DRAW"SBBM2,9G"+D$+D$+D$+
D$+D$+D$+D$
and run.
If you offset the horizontal locator
value in Line 21 from 2 to 5, you get
a variant chain that looks like a pair of
twisted ropes. Run this, then restore 2.
Let us make a vertical rope so it
crosses in the center. To make it go
down three boxes and right one box, we
get M+1,3, and to go in the opposite
direction, we get M~l, 3. Note: Horizon-
tal value is the first element!
30 E$="M+1,3M-1,3"
31 F$=E$+E$+E$
35 DRAW"SBBM129,G"+F$+F$+
F$+F$+F$.
Now run.
To make the strand another way,
type:
36 DRAW"SBBM12B,G"+F$+F$+
F$+F$+F$
Two things stand out. First, the links
are slightly larger, and second, we have
a mismatched pair of strands. This can
be repaired. The strand in Line 36 must
have M-1,3 inserted in front of the
closing quote. Line 35 must have
+M+1,3 added after the final +F$. Run
this.
Note the horizontal values in lines 35
and 36. This was done to maintain a
shape as close as possible to the hori-
zontal rope.
Problem to solve! Notice the vertical
strand is off-center. It crosses the hori-
zontal rope neatly, but overflows off the
screen at the bottom. Can you center it
better? Try to work it out.
First, drop one +F$ from both lines
35 and 36, and run. We could use about
2/2 links on each vertical strand. One
link equals +E$. Let us insert +E$ in
both lines 35 and 36. Caution: Not at
the beginning or the end! Now run.
Let us add another link, +E$, right
next to the +E$ we injected into the two

final +"M+1,3" and tack on +E$ and
run it, That leaves one piece missing at
the end of Line 36. Add +"M+1 , 3" and
run. It isn't perfect, but it will do,
By the way, what was this tutorial
supposed to cover? It seems I wandered
off down some primrose path. Even
though it was difficult to create the
vertical rope, wasn't it a fun challenge?
Now, you know two ways to make a
rope.
Suppose we wanted to make a three-
strand rope? First, mask lines 35 and 36
with REM markers to get them out of the
road. Re-size lines 20 and 21. Change
Line 20 to S1G and delete SB from Line
2!. Since both lines will be the same size,
a second S1G would be redundant. Run
this.
Lop off four each +B$s and + D$s from
lines 20 and 21, and run. Re-center by
inserting 0 in lines 20 and 21 to make
the horizontal value 20. Now run.
The size must be enlarged to S24.
Make the change and run. To make the
third strand, type:
22 DRRW"BM12,101" + B$+B$
Rekey lines 20 and 21, then type:
20 DRflkTS24BM23,99"+B$+B$
21 DRflkJ"BM15,95"+D$+D$
and run.
The starting locations (H,V) were an
exercise in trial and error, They were
adjusted, this way and that, until the
strands looked moderately twisted.
We now have staggered strands. Re-
center by adding + ! 2 to each horizontal
value in lines 20 through 22. Now run.
Allwe have to do is tie up the loose ends,
I will have to ask CoCo to cheat and
resort to LINE statements to do the
trick:
40 LINE(20,94 )- (34,102) ,
PRESET, BP
41 LINE(21B,93)-(256,102) ,
PRESET, BP
Now run it.
Incidentally, there are better, more
complex ways to tie the ends of the
braided, three-strand rope, That would
send us further down another primrose
path, Suffice to say, using LINE was
good practice. How did I come up with
the values in the two LINE statements?
1 used PSET,BP. This allowed me to see
what was being zapped because little
windows overlaid the dangling ends.
Merely adjusting the values to encom-
pass the desired portions indicated
vividly what was being blanked out. The
mission was finalized by changing the
PSET to PRESET.
Save it as Listing 1 and type NEW. Here
is a problem! Using lines 10 and 100,
create a DRAW LINE 20 and usingM-2,4,
manipulate the pluses and minuses to
create a diamond shape in size SIS.
Usingthe A option, make a diamond-
shaped cross. Going further, an optical
illusion was created, using the same
game plan. Type NEW. Quickly, key in
OPTICAL and run. If you stare at the
display, it seems as if the diamond tends
to rotate on its vertical axis, sometimes
clockwise and sometimes counterclock-
wise.
Your homework assignment is to
make a small program using 10
PMDDE4 , 1 : PCLS :SCREEN1,0 and
create the eyeless wonder in Figure 1
using the DRAW statement. Think of it as
if all of the tick marks at the end of each
straight segment are dots. You must
connect all the dots to make the lines
flesh out the face. Begin anywhere you
like. When you mustjump to a new area
to connect up with another group of
lines, use B in front of one of the eight
normal directions, UDLREFGH, or before
M ? when you must move at some angle
that is less than 90 degrees.
For example, from the end of the
figure's right jaw, up to the outer edge
of the right eye, BR2BU9 will bridge the
gap by making a 90-degree angle; to the
right two units and then up nine units.
If you are really into the M option,
BM + 2,-9 will do the same thing more
directly and d raws an invisible line
linking the two areas.
Save your "face" program. Next
month, we shall continue. I will make
the official drawing for the tutorial
When you compare my rendition with
your version, you may be shocked to
realize that even though we created the
exact same figure, our program lines are
as different as the two sides of the
moon. U

You Need to Know
When to Stop
By Dan Downard
Rainbow Technical Consultant
/ am having problems with my new
printer. It's a Brother M-/I09. The
problem is when printing out a fair
amount of data, it loses part of the data
and resumes somewhere down the line.
Here is how I have it connected:
DIN Printer DB-25
1 Unconnected
2 to 4
3 to J
4 to 3
I am running at 9600 baud and used the
line delay pokes to slow it down. I am
now using 151=128, 152-64. It still loses
data in the middle of the printed page
or close to the end. I have slowed the
printer all the way down to 600 baud
with no luck.
Mike Tolbert
(MIKEGT)

Mike, we haven't touched the subject
of printers for a while, so let's get down
to the basics. Your CoCo uses three of
four pins on the DIN plug, better
known as the serial I/O connector, to
communicate with the printer. The
pinouts are as follows:
Pin 1 Not used N/A
Pin 2 Handshake/ busy Input
Pin 3 Signal ground Common
Pin 4 Data Output
Dan Downard is an
electrical engineer
and has been in-
volved in electron-
ics for 27 years
through Ham radio
(K4KWT). His in-
terest in computers
began about eight years ago, and he has
built several 68XX systems.
The industry standard for serial
communications is called RS-232. RS~
232 uses a 25-pin connector called a DB-
25. RS-232 calls for the following
connectionsto a DB-25 connectoratthe
printer:
Pin I-

Pin 3-

Input
Pin 7-
SG signal
ground
Common
Pin 8-
DCD data car-
rier detect
Input
Pin 20-
DTR data ter-
minal ready
Output
At least we know what the pinouts are
on the CoCo. The problem is at the DB-
25 end of the cable. First of all, let's
assume we are dealing with serial I/O.
Your printer manual should give the
pinouts for the RS-232/ DB-25 connec-
tion. Even though it's an industry
standard, some printer manufacturers
use different pins for the handshake
signal. Use the RS-232 pinouts above to
identify your printer signals. If you
don't have a DB-25 connector, match
the signal descriptions with those given.
The following connections should
work:
DIN
DB-25/ Printer
Pin 1
No Connection
Pin 2
Pin 20
Pin 3
Pin 7
Pin 4
Pin 3
In most cases you must connect a
jumper between Pins 4,5,6 and 8 on the
DB-25 connector.
If the handshake signal is properly
connected, you shouldn't have to worry
about line delays, etc. This is accom-
plished by a hardware signal between
the printer and the computer. Just as an
explanation of your problem, your
printer has a buffer. The buffer is
accepting characters at a faster rate than
it can print. When the buffer is full, your
CoCo is still sending, because no signal
has told it to stop. As a rule of thumb,
baud rate = characters per second x 10.
In other words, if you have a 120-cps
printer you should be able to print 1200
baud without any handshake signals.
This tidbit assumes that you have no
buffer, but it's close enough. Obviously
your printer is not capable of 960 cps.
Leave Out the Spaces
Regarding the question in your May
1987 column from Bill Hodges, about
underlining every word: The computer
does exactly what you tell it to do. Most
underlining routines are set up to under-
line only characters, not spaces. The
solution? Don't use any spaces. So, use
an underline character where spaces
should be.
Marc I. Leavey

Thanks for the nifty hint, Marc. I
have been reading your ham radio
July 1987 THE RAINBOW 161
column ("RTTY Loop" in 73 Amateur
Radio) for a long time and am sure glad
to hear from you. 73's de K4KWT.
The Unpublished Feature
In replying to a writer concerning a
Teac 55 B floppy disk drive, you stated
that the user's drive was operating
normally because ''The disk motor is
turned on for a few seconds to allow the
drive to get up to speed before any
operation takes place. " This is true.
However, your reader's query was
"when I either insert or extract the disk,
the motor runs for about ten seconds on
its own before the lever is engaged. Is
this normal?"
It is an unpublished feature of the
Teac drives (I have one myself) that they
turn on the spindle motor when a disk
is inserted or removed from the drive.
The spindle motor will remain running
for about ten seconds, as your reader
noted. I'm told that this feature allows
for better "clamping and declamping"
of the disk hub upon insertion and
removal. This is an isolated hardware
case j which is peculiar to Teac drives,
and is not related to the normal V/2-
second, motor-on delay that is part of
Radio Shack 's normal Disk BASIC.
Don Hutchison
(DONHUTCH1SON)

Thanks for the info, Don. I am also
informed through Delphi and Marty
Goodman that Shugart, Panasonic and
Matshushita 455 drives all have the
same hardware delay built in.
What's a Control-Z?
/ operate amateur radio and got my
CoCo 2 to use on a packet radio station.
It works just fine on packet, but in order
to use the major BBS, you need to sign
your message with a CONTROL-Z. Is it
possible to get a CONTROL-Z out of the
CoCo 2?
Billy R. Thomas
Streamwood, IL
You must be using some kind of
communications, or terminal, software,
Billy. Most of the CoCo 2 terminal
programs I have seen use the down
arrow as a control key. By pressing the
down arrow and the Z key at the same
time, a CONTROL-Z will be sent. Read
the manual for the software in question
to confirm this!
How Much Memory?
/ just bought my new CoCo 3 and
typed PRINT MEM, and it said 22824 with
my disk drive plugged in. Is something
wrong with it? I thought you got more
162 THE RAINBOW July 1987
memory with a new 3. Also, what do
you do to disable the reset button?
Sean Bishop
Hazard, KY
Sean, as long as you are using Disk
BASIC, the memory in your CoCo 3 is
limited. Keep in mind, though, that
CoCo 3 does have the ability to store
graphics pages in the extended memory
area. So even though the memory avail-
able is still about the same, it can be
used for programs and variables, and
your OM Errors will be fewer.
To take advantage of the extended
memory of your CoCo 3, I would rec-
ommend programs written in OS-9
Level II. Even though an OS-9 process
is limited to 64K, there are ways to take
advantage of the full 512K of memory
allowed. Dale Puckett and Peter Dibble
are writing a new book about OS-9
Level II that will be available later this
year.
Updating the CoCo 2
/ have a 64 K CoCo 2, two double-
sided disk drives, Epson LX-80, DCM-
3 and a Multi-Pak. I have some ques-
tions about getting a monitor (non-
RGB). Would I need some kind of
driver/ adapter to hook it up to my
CoCo 2? I would also like to have 80
columns. Do I need an 80-column card
or something? I would also like to gei
a 64 K buffer for my printer. How do
they work? Does it have a CPU in it?
Craig J. Vincek
Benton, KY
1 would recommend buying a CoCo
3 instead of investing in more hardware
for your CoCo 2, Craig. First of all, a
video driver is not sufficient to produce
readable 80-column text with a CoCo 2.
Therefore, we will assume that you will
need an 80-column interface, such as
those made by Disto and PBJ.
As far as the buffer is concerned,
there are three types that come to mind.
First, most printer manufacturers offer
a buffer as part of the printer. Second,
there are hardware printer buffers
available. Try the Spectrum Projects ad
in this issue. Last, but certainly not
least, is software spooling. Using this
method, the printer operates as a back-
ground task while other programs are
running. This is a built-in feature of OS-
9. Programs are also available for RS-
DOS to do this, but I am not aware of
one for the CoCo 3. I'm sure it will be
available shortly.
RS-232 ROM
In your March 1987 column, you
suggested to Vince Falcone to remove
the R OMfrom his RS-232 pack. Would
you please show a schematic of the pack
so that I will know which chip to re-
move?
Kevin Krug
Derwood, MD
Kevin, we cannot publish a schematic
here but will give you enough info to
pick it out of the Pak. In the RS-232
pack, you will find two large chips. One
has 28 pins and is indicated with the
symbol Ul on the circuitboard. The
other chip has 24 pins and is called U3.
This 24-pin chip is the ROM. If the chip
is socketed, simply remove it. If it isn't
socketed, you will need to desolder Pin
20 and bend it up out of the way.
Scroll Stopper
I tried your rewritten version of Disk
Directory Lister. There are a few ques-
tions I would like to ask. When I try to
run it on a disk, I get an NE Error. Is
there a way to halt the program when
it reaches the bottom of the page so that
it doesn't overflow to the next page?
Willie E. Turner
Baldwin Park, CA
It sounds as if you are trying to read
an OS-9 disk, Willie. OS-9 uses a dif-
ferent directory structure. Direct was
written for RS-DOS directories.
Another thing to look for is copy-
protected disks. As far as making the
listing stop, try inserting the following
lines:
45 LN=1
305 GDSUB600
600 LN=LN+1
610 IF LN<59 THEN RETURN
620 FDR LX=1 TO B
630 PRINTH2
640 NEXT LX
650 INPUT"HIT RNT KEY TO CON-
TINUE"; IN$
660 LN=1
670 RETURN
I'm glad you liked the program. Have
fun with it.

BITS AND BYTES OF BASIC
BASIC09 and Level II
Focusing on Modules
By Richard A. White
Rainbow Contributing Editor
Everything was happening at once. Income tax and this
column's deadline were near at hand. Preceding them
was the Chicago RAINBOWfest. I decided to get the
taxes out of the way and they were getting on well when Level
II arrived on a Tuesday. I hurried home to format disks and
make backups. Well, I could not even format a disk and had
to fall back to Level I to get the backups. The CoCo 3
sometimes "went west" even before the Level II boot was
complete. Things like this are totally frustrating. Wednesday
evening brought the news that two friends had experienced
identical problems, and the search for a solution was on. 1
felt a tad better knowing it was not just my machine.
A Thursday evening session on the Delphi OS-9 Forum
brought an answer: Some old 12-volt disk controllers could
not take the 1 .8-M Hz clock speed. So the disk controller swap
began and solved the problem. Our controllers dated from
February 1983 when we made a group buy of drives. Some
earlier and later 12-volt controllers work as all 5-volt only
units do.
Still there was a bit of time to work with Level II and
BAS1C09, which comes with it. Early on it was apparent that
128K would not cut it. I solved this at RAINBOWfest by
purchasing a 512K upgrade, as did many others. BAS1C09 is
nearly identical with the Level I version except for support
for CoCo 3 graphics. This is going to take some careful
digestion, all the more reason to focus, for now, on
applications common to CoCos 1, 2 and 3.
My first order of business was to get a Level II boot set
up to take advantage of windows and the added memory,
then work up the program for this article. That done, it was
time to sit back and be impressed. Wow, we have been
scraping for memory for years. Now I load nearly everything
I routinely use in memory at boot and still have half the

management program.
available memory left. I start BASIC09 with a nice big buffer
and still can go to OS-9 and have plenty of memory to do
anything I want.
Level II provides two ways to leave BASIC09 to use OS-9
utilities. One is to type $ at the B: prompt. This puts you in
OS-9. You get back to BAS1C09 by pressing CLEAR-BREAK
(CTRL-BREAK on the CoCo 3). However, with a number of
windows active on the CoCo 3, pressing the CLEAR key
advances one to another window. This can be done from a
running BAS1C09 program. 1 discovered some of the protec-
tions built into OS-9. For example, it is impossible to change
or delete a file in use by a running program.
Documentation for Level II BASIC09 is much improved
over the Level I version. Program examples are given for
virtually all commands. Unfortunately, some of the early
examples use line numbers. Perhaps someone thought people
could not go off line numbers cold turkey. Most later
examples dispense with line numbers. What is not so
apparent in these examples is the importance of modularity
in BASIC09.
A good BASIC09 program consists of a number, perhaps a
large number, of separate modules. Some will be drawn from
a library of modules that have been used in other programs.
Others will be written for the application. This simplifies
writing the modules and testing them to begin with. It also
makes it easier to upgrade programs later. For example, I can
quickly write an editing module that may be a simple
substitution editor and come back later to write a new more
powerful version.
Modules have memory implications. They can be loaded
as needed and killed out of memory when they are no longer
needed. Parameters allow large blocks of variables to be
passed to other modules to be changed and returned to the
calling module.
I am focusing on modules since I plan to discuss the
beginning modules of a much larger program that will roll
out over the next few months. The program now goes under
the name PersonFile. It's basically an enlarged mailing list
and membership program. All such files have common needs,
the name and address, telephone numbers, dates and some
general note fields. The intent is to provide a generic record
structure whose fields can be renamed to meet a variety of
July 1987 THE RAINBOW 163
purposes. As a computer user group membership file, the
basic address information is required along with expiration
date, perhaps date joined, home and office telephone
numbers and miscellaneous interest information. On the
other hand, the Christmas list file needs addresses, telephone
numbers, birthdays perhaps, names of others in the family,
etc. These are the same fields, just different uses for the fields.
I like to start with a "main" module. Basically, it
dimensions the record variables, opens and closes files and
calls other modules that do most of the work. One has some
discretion as to what goes in the main module. Some short
routines may be better in the main module because of the
memory overhead in passing parameters and defining them
in separate modules. Still, almost everything must be
considered for its own module.
Rather than start with main, I will first deal with two
"library" procedures that ! have re-used from previous
programs, isupper simply converts any lowercase letters to
uppercase. This way a user may answer with either a y or
a Y, and the program needs only test for a Y.
PROCEDURE isupper
000$ DIM oount , 1 ine_length : INTEGER
000B PARAM answer; STRING [40]
0017 DIM ascii: INTEGER
,00 IE DIM char » STRING [ 1 ]
00 2 A DIM work_string : STRING [ 40]
0036
The first section of the program defines the variables. A
variable defined with dim is local to this procedure, param
answer : st ring [ 40 ] defines a string variable, up to 40
characters long, that will be provided by the calling
procedure. Note that BAS1C09 strings are dimensioned with
a specified length for which fixed storage is provided. A
shorter string of characters may be put into the variable, but
any characters in excess of the specified length are lost.
BAS1C09 supports long variable names, which are a major help
in program readability. While theseuse memory in the source
code, they are stripped out when the procedure is packed.
0037 count :=1
003E line__length:=L£N (answer)
0047 work_string:= M "
004E
BASIC09 does not automatically initialize variables. As
initially dimensioned, work_s tring contained whatever
garbage was in the memory BAS1C09 allocated to it. The
expression wo rk__s tring: sets its length to zero so
BAS1C09 will disregard everything in its memory space.
004 F WHILE coant<line_length+l DO
005F ascii : =ASC{MID$ {answer , count , 1)|
006E IF ascii<96 THEN
007A char=CHR$ (ascii)
,0,083 work_strir>g^^rk_strir^cJ^ar
008 F count : =count+l
009A ELSE
009E char :=OiR$ (ascii-32)
00AA work_string=^^rk__string-K±iar
00 B6 count : =count+l
00C1 ENDIF
,00C3 ENCWHILE
00C7
Now, isupper gets the ASCII value of each character in
the string answer and tests each value. If ASCII<96, the
character must be uppercase, a number or punctuation mark
so ASCII is converted back to a character and added to
wo rk__s tring. Characters with ASCII values greater than 96
must be lowercase. Subtracting 32 will make the conversion
to an uppercase number. The new ASCII is converted back
to a character and added to work__s tring.
The whi le-do-endwh i ie keeps the program looping until
each character in answer has been tested. It and the i f-then-
eise-endif are control structures. Each BAS1C09 control
structure has its own end statement. Above we see endi f and
endwhiie. Others we will see are endexi t and endioop.
Most are familiar with NEXT which ends a for-to-next
structure.
00C8 answer :^=work__string
00E0 END
In passing the string answer to isupper, BAS1C09 really
passed the memory location of answer. Whatever isupper
puts into answer will be known to the calling procedure when
it regains control. So, we can assign the uppercase string in
work__s t r i ng to answer to get it back to the calling
procedure, end terminates isupper and passes control back.
By the way, the numbers to the left are offsets from the
beginning of the program in Hex bytes to the beginning of
the line.
PROCEDURE printat
0000 PAP AM col, rw; INTEGER
00 JB PRINT CHR$(2) ; CHR$ (col+32) ; CHR$ (rcwK$2 ) ;
0021 END
Maybe I should rename printat to locate to be
consistent with CoCo 3 basic. It simply receives a column
and a row number and uses the print statement to move
the cursor to that screen location. We will use it frequently.

OK, here starts the procedure main. Since we have 15
field names, we will need an array to store them in.
Field_nam_e( 15) provides this array. Next, things get muddy
fast, type defines a new variable type that is used in the same
way as integer, stringf] and the other atomic variable
types. The new type add_rec consists of five, I5-character
strings named first, last, addl, add2 and city, plus a
four-character string named zip4 and the five-character
zip5. The names of these strings are descriptive of their uses.
The second new type, data_rec, provides storage for the
remaining data to be in the record. Finally, storage for the
records is provided by dim addrec : add_rec ; da-
tarec : da ta_rec.
Understanding how BASIC09 stores its variables will help
in understanding the type statement. Type add_rec consists
of five, 15-character strings, one of four characters and
another of five characters for a total of 84 characters. When
the program comes to dim addrec : add^rec it allocates 84
contiguous bytes of memory and maps it according to the
type add_rec= statement. The variable first gets the first
1 5 bytes, i as t gets the next 1 5 and so on. When BAS1C09 sees
addrec . f i rs t : ="j ohn", it knows to look in the map
provided by add_rec to find the place to put "j ohn". "john"
will go in the first four bytes of the 84 bytes allocated to
addrec.

print chr$[12) is the equivalent of CL5 in CoCo BASIC
and clears the screen. We have discussed the printat
procedure. Now we see how to call it: run printat[0,B).
The 0 and 8 are the column and row parameters we are
sending, run is quite flexible. It can call a source code
procedure in the BAS1C09 workspace, a packed code proce-
dure inside or outside the workspace or a machine language
procedure line like inl<ey below.
Next we get the filename of our database. The system will
use a number of files, but the program will handle naming
using this root word. The variable file will be used for a file
path number, which is assigned when a file is created or
opened. The number will always be four or higher, As long
as f ile=0, we know that no files have been opened.

inkey looks for an input character and then lets the

I said that I did not want to go to the create routine if
files were already open. Here is a dual test where the user
had to have entered a 0 and file must be 0. When these
conditions are met, init is run and sent field_name,
addrec, datarec and file_name as parameters, These
parameters allow init to access over 300 bytes of storage,
and init will change each variable in these records. Now you
can see why we did not want to be able to call init while
some other file was active.
Once having passed the init call, there will be a file
somewhere to work on. If ini t was used, it will have placed
two files on disk. Otherwise, the filename entered should be
a path to pre-existing files. In either case, filename has
suffixes appended and two files are opened for update. This
means BAS1C09 may either write to the files or read from them.

With the files open, we go forward to other work. We can
rename fields at any time since that does not change the data.
The procedure rename f does this. All it needs is the field
name array and the file path number for the file where it will
store the modified array.
In order to test the init and rename f procedures, main
needed to provide some minimum housekeeping. Accord-
ingly, the exit routine was written. Meet exitif-then-
endexit. This construction provides a way to include all
sorts of final housekeeping tasks after the then prior to
finally leaving the loop. In our case, we close the files,
exi ti f is the only way to exit a loop without using a goto.
It can be put anywhere in the loop, and there can be multiple
exi ti f -then-endexi t constructs in a given loop. It can be
used with any of BASiC09's looping control structures.
After an exi ti f-then-endexi t, control goes to the next
statement after endloop. In our case it's end, which
terminates the procedure.
At this point, I think I have dispensed sufficient BAS1C09
for one sitting. Next month we will take up the init and
renamef procedures and get started on enter/edi t. /P*

OS-9
KISSable OS-9
An OS-9 Convert Speaks Out
By Dale L. Puckett
Rainbow Contributing Editor
Steve Bjork first worked with com-
puters while studying electronics
during the early 1970s when he
enrolled in his programming course at
a Los Angeles area college. Before long,
Bjork had "put together" his own elab-
orate calculator — a computer com-
pletely built with discrete components.
"I used the 7400 series technology to
come up with a whopping 64 bytes of
memory, four bits or one nibble wide,"
he said. "It cost me more than $200 to
build this overgrown calculator. Today
I can buy a 128K CoCo 3 for the same
money."
Bjork continued his education in
computer programming and electronics
at several colleges in Southern Califor-
nia. "While I was at San Diego, they
were developing UCSD PASCAL," he
said. "As a student I got to work on a
few of the trivial parts of the program
and served as a guinea pig to test the
rest."
In 1970 Bjork went to work for the
Dale L. Puckett is a
free-lance writer
and programmer.
He is author of The
Official BASIC09
Tour Guide and co-
author, with Peter
Dibble, of The Com-
plete Rainbow Guide to OS-9. He
serves as direct or -ai-large of the OS-9
Users Group and is a member of the
Computer Press Association. Dale is a
U.S. Coast Guard lieutenant and lives
in Rockville, Maryland.
first of several small software compa-
nies. By the end of the decade, he wound
up at DataSoft and was immediately
assigned to develop software for the
Color Computer. It was at this time that
he grew to know and love the 6809 for
all its power and simplicity. While there,
he racked up credits for Sands of Egypt,
Clowns and Balloons, Zaxxon and
many more hit Color Computer games.
In 1983 Bjork left DataSoft and
formed his own company, SRB Soft-
ware. A few months later, Radio Shack
named OS-9 as the official operating
system for the Color Computer. While
it took them nearly a year, with Bjork
kicking and screaming all the way,
Tandy finally convinced SRB Software
that OS-9 was the way to go. How?
"Since Radio Shack was no longer
accepting programs that were not devel-
oped on OS-9, the choice was simple,"
Bjork said. "If you wanted to write
software for the Color Computer, you
had to use OS-9."
While the kicking and screaming
made it a bittersweet experience,
Bjork's introduction to OS-9 was like a
blast from the past.
"After I had a chance — or should 1
say after I was forced — to sit and look
into OS-9, I began to rediscover what
computers are all about," Bjork said.
"When I was in college, most of the
computers I used were mainframes that
had elaborate operating systems built
in. This cut down the amount of work
the programmer had to do. I re-
experienced this same phenomenon
with OS-9."
How did Bjork learn OS-9? "1 must
admit I had some help from Tandy and
a good friend in Fort Worth who was
able to answer my questions," he said.
"And even though the OS-9 manuals
were technically oriented, I was already
familiar with operating systems and
what they were supposed to do. There-
fore, OS-9 was not foreign to me. But,
like most folks, I find that additional
reference material is always handy and
I bought one of the first copies of the
Complete Rainbow Guide to OS-9.'"
When we asked for his advice to first-
time OS-9 users, Bjork suggested they
talk to other users. He cited Special
Interest Groups such as rainbow's OS-
9 online on Delphi and the OS-9 SIG
on CompuServe as excellent sources of
both contacts and information for
beginners. He also encouraged them to
seek help at a local club.
"Talk to these people," Bjork said.
"They have run into the same problems
and they can help you. Also, don't be
afraid to buy extra books on the subject
and read them! Most importantly, if
you haven't been to school for a while,
you may need to relearn how to learn
— because you forget."
When Bjork formed SRB, his first
projects were Level II products, but he
did cut his teeth with Level I. His first
Level II product hasn't hit the market
yet. What is that program? He can't
comment. Why?
"Because specifications change and
contracts may be cancelled," Bjork said.
"If that happens, a product can become
vaporware. And one vaporware pro-
July 1987 THE RAJNBOW 167
gram can ruin the reputation generated
by 10 excellent products."
We asked Steve to look into his
crystal ball and tell us what he sees for
the future of OS-9, "Generally, most
general software developers feel that we
now have, in the CoCo 3, a computer
system with the capability of an IBM
PC," Bjork said. "In other words, many
companies that felt the CoCo didn't
have the power of other machines are
now in the process of porting their
existing programs or developing new
ones for OS-9 Level II. Koronis Rift —
ajoint venture by Lucas films and Epyx
— is a good example."
Lucas has been developing software
for microcomputers, and Epyx has been
marketing them for the past few years.
What do these companies think about
the CoCo 3 and OS-9 Level II?
"They say the OS-9 Level II port of
Koronis Rift is the best version on any
micro," Bjork said. "And this type of
response is typical of many developers
today."
Bjork feels that we will finally start to
see the high quality software that has
been missing from the Color Computer,
"And it will all be running on OS-9
Level If — no exceptions!" he said.
Could Bjork give us any hints about
what we can expect to see? "In addition
to games, you should see many home
applications and quite a few small
business applications as well as produc-
tivity software packages like More and
Side Kicky
What time frame? Bjork- thinks it will
be April 1988 before we see what is
planned now. "It takes many months to
develop hardware and software in a new
environment," he said. "For example, it
took 13 months to put my high resolu-
tion joystick online.'*
Bjork thinks that most of the prod-
ucts being developed today will be sold
through Tandy. "Let's face it, they have
a very effective d istribution system.
Also, most of the software in the future
will use the windowing capability of
OS-9 Level IL
Multi- Vue Will Make Life Easier
"We're going to see a new class of
software with more power and more
sophistication, but the underlying fac-
tor will be the greater ease of use of the
software," he said. "User-friendly will
become real!"
How? "First of all, Multi-Vue - a
user program that can tie all application
programs running under the OS-9 en-
vironment together — will make it
happen," Bjork said. "Multi-Vue will
have the same effect on programmers as
the Macintosh toolbox. Both environ-
ments force a programmer to make his
programs user-friendly."
Bjork thinks that most programs
developed in the future will be able to
run on their own from the shell but will
also be able to be run from Multi- Vue.
"This means Multi-Vue will control
their operation," he said. "Multi- Vue
will vary their window sizes, call them
into being, put them to sleep or remove
them completely"
Is there anything special a software
developer must do to make sure his
programs are compatible with Multi-
Vuel "They must be able to receive a
signal from Multi-Vue that tells them
the window size has changed and then
be able to use that new window size,"
Bjork said. "Existing programs — those
on the market right now — will simply
stay in one window."
What must a programmer do when he
receives the signal from Multi- Vuel
"After you receive the signal, you
simply clear the screen and then do a
call to find the new window size. After
making this call, your program should
run within the bounds of the new win-
dow, " Bjork said. "Programs today
check to see if Multi- Vue is alive by
doing a ge ts ta t call to see if windows
are available."
How can software developers com-
pete in a marketplace driven by users
demanding friendly and intuitive soft-
ware? "Without Multi-Vue, you must
think about what your customer is
going to do with your program and how
he is going to use it," Bjork said. "The
more intuitive you can make a program,
the better!
"The second step — if you have
Multi- Vue use the extended system
calls. These calls will let you put up a
menu automatically just by doing a
system call. When Multi-Vue returns
control to your program, it will tell you
if any of the options on a menu were
selected," Bjork said.
Multi-Vue'^ automation accom-
plishes two things. First, it saves code.
Second, it makes for uniform menus.
The people who buy your database
program will load or save their data in
exactly the same way they load or save
their text files when they work with a
word processor from another vendor.
They will only need to learn how to use
their computer once. They can then
concentrate on the job they are trying
to do.
Tandy hopes the standardization
brought about by Multi-Vue will force
all programmers to provide a friendly
user interface. Further standardization
can be expected from the Multi- Vue
clipboard. The clipboard should prove
to be a very handy tool because it's
always in the system and ready to use.
It gives developers a standard way to
pass data from one application program
to another.
Steve also had comments about the
Level 11 manuals. "They make excellent
reading," he said. "But, you must take
the initiative to read them. If you are a
beginner, it*s obvious that you must
understand everything in the beginning
chapters. Don't skip a page!"
And, if you're an expert? "Don't skip
over the beginning chapters," Bjork
said. "You'll discover many subtle
nuances are covered early in the man-
ual"
With Steve not talking too much, we
guessed he must be under contract to
develop several products. Color Com-
puter Artist is in the catalog. Could it
be his?
"The title is a little misleading," Bjork
offe red. "People really don't realize how
powerful the OS-9 Level 11 windows
are! It's not that intuitive. But, you can
draw pictures of one size and one color
in one window and then re-display them
in a different window that is a different
size and a different mode. Even though

you are using the same data, the picture
will display properly. When you try this
with the different graphics modes while
running under Disk Extended BASIC,
you lose half the picture or fill only half
the screen. And often, you can find no
rhyme or reason."
What else will the windows do? "If
you shrink the window, your image
shrinks accurately," Bjork said. 'The
scaling algorithm is really accurate."
How will we get a hard copy of these
fantastic images? u OS-9 allows many
different types of dump programs,"
Bjork said. "Many will be available.
You simply grab a line, put it in a buffer,
read it and then send it out. You should
be able to dump the active window or
the entire screen with some of these
programs."
Will we see big companies with big
names porting their software to OS-9
Level II? "I can't name names, but most
of these companies are very impressed,"
Bjork said. "In fact, many of them are
giving me a run for my money. They've
put me under a lot of pressure. I'm a
one-man operation. A big company can
hire a dozen programmers to do a
project."
How can a company afford to invest
that much in a single program? "Most
companies make most of their money in
the first six months following the release
of a program," Bjork said. "If they get
out there first, they're OK. If they don't
get there first, they may be lost because
everybody that has to have a copy gets
it right away. In a sense, a company
can't afford not to hire a dozen pro-
grammers and be first."
Come on, Steve, any hints? "You're
going to see CAD and integrated pack-
ages like Microsoft Works," Bjork said.
"All these things are hot prospects for
entrepreneurs looking at OS-9 Level II
on the CoCo 3. It's not a function of
Level H, or windows, or the CoCo 3
alone! It's what happens when you
combine them. 1 '
Bjork feels this synergism will be
expanded even more by Mulli-Vue.
But, he doesn't think CDI will have any
effect on the CoCo market. "Here's an
analogy. You could use your CoCo to
control your VCR. But, your VCR
already does it better," he said.
Any afterthoughts or advice? "When
OS-9 Level II first came out, everybody
wanted to patch this, change this, and
rearrange that. But, there are already
commands available that let you change
most of the things you want to change.
So many times I've seen people try to
patch the window device descriptor
when all they had to do was use the

"One thing needs explaining," John-
son said. "That's the high-performance
nature of the floppy disks built into the
system. They are high-density drives
that hold as much data as an 8-inch
floppy. They run at 360 revolutions per
minute instead of 300. But, we've made
them dual speed so you can read all of
the standard OS-9 formats."
Johnson's drives let you store 4,480
sectors on each disk — or just slightly
more than 1.1 megabytes. "The
throughput is close to that of a hard disk
with these floppy drives," Johnson said.
They transfer data at twice the rate of
a standard drive, plus they step between
tracks in 3 milliseconds."
By designing a caching floppy disk
controller system that operates inde-
pendently of the processor, Johnson
was able to set up Diskmaster to run
without pulling up the halt line on the
CoCo 3 1 s 6809. Diskmaster is also
partially intelligent, keeping the most
recently used sectors in RAM memory.
In fact, Johnson's algorithm also con-
siders the frequency of use so your
CoCo 3 doesn't need to go out and read
the disk very often.
Johnson demonstrated by typing di r
x. Everything worked normally, albeit
very quickly. Then he repeated the
command. This time it ran even faster,
and the drive light didn't come on.
Magic!
The Diskmaster drives are set up to
issue a disk change signal so, when you
change disks, the buffer is flushed and
youstart with a fresh read. The software
also always does a write through to the
disk so you won't get caught with a non-
updated disk.
If you are in a real hurry, you can
purchase an optional internal RAM
disk that holds up to a megabyte and a
long int

half ofRA M disk. Johnson hopes you'll
plug in his Diskmaster and forget you
ever needed a Multi-Pak interface.
After Johnson demonstrated Disk-
master, we asked him what his update
policy was for SDisk. "We're rewriting
it for the CoCo 3, and OS-9 Level II will
have a separate version," he said. "The
update price will be about $ 15, and we'll
make the setup easy."
When we asked Johnson why anyone
would want to buy SDisk for Level II,
since CC3Disk has double-sided and
quad-density capability built in, he said
that SDisk will give users a way to
format 48-track-per-inch disks on 96-
tpi drives. "The standard CC3Disk
doesn't allow you to do this," he said.
"The Level II format command does
not give you the option. SDisk will! The
Level II SDisk will do everything the
older Level I versions did. Additionally,
if you want to use the PC transfer
software on the CoCo 3, you will need
the new Level II SDisk.
On the hardware side of the house,
Johnson noted that he would also be
updating the CCRam disk for OS-9
Level II running on the CoCo 3. You'll
receive a replacement PAL chip that lets
the unit run at 2 megahertz.
July Listings
Dennis Duke is back this month with
a C program that will generate a table
of prime numbers. Prime_tbl prompts
for the lowest and highest number you
want in the table. To get a hard copy,
you redirect your standard output path
to your printer: 059: prime_tbl > / p.
If you are interested in how to write
a BASIC09 program that changes the
format of a text file, check out MAC-
List from WIZ author Bill Brady. He
wrote the program to make OS-9 text
files generated by DynaStar compatible
with text files used by word processors
running on his Macintosh Plus.
DynaStar puts a carriage return at
the end of every line. The Macintosh
word processors think that two carriage
returns mark the end of a paragraph.
They take care of the word wrap auto-
matically. Brady also handled the prob-
lem caused by text that has been in-
dented using spaces. He removes all
spaces directly following a carriage
return. Hopefully, MACList will prove
to be a useful model you can follow
when you need to write a BASIC09 pro-
gram to manipulate your text files.
That's it for July. Until next month
. . . keep on hacking! □

Dr. Preble's Programs
Striking A Blow For
■ . Freedom is nothing else but a chance to be better . . .
— Albert Camus
*** Mental Freedom
for CoCo 2 and 3!
(Will not work withCoCo 1)
A Thought-Controlled Video Challenge
We call it The Preble Thoughtware.
DOES GREEN BLOOD flow in your veins like Mr. Spock? Is your mind well
ordered? Or is your mind a mass of conflicting emotions like most
humans?
THOUGHTWARE may answer these questions and more.
IMAGINE! Some day, a computer so advanced that it responds to your very
thoughts and emotions. Imagine, some day, ihoughl-conlrolled
graphics: levitation and materialization!
PLUG IN YOUR MIND and UNHOOK YOUR JOYSTICKS -
now! The Radio Shack Color Computer has many ad-
vanced capabilities, just waiting to be tapped. Dr. Preble's
Programs combines the advanced technology of the CoCo
with the amazing Radio Shack BIOFEEDBACK MONITOR
to bring you "Preble Thoughtware."
THOUGHT-CONTROLLED VIDEO CHALLENGE? Unlike any
video game you have ever played, Thoughtware tests your
ability to handle stress, to remain calm under adverse
circumstances.
LIGHTNING FAST reflexes will do you no goodhere, unless you
first tame the fickle dragon of your mind.
YOU HAVE SELF-CONTROL? Many people can keep a
"Poker Face'^ even when they are worried so that others
may not notice; but can you really stop the worry itself? Thoughtware
will find out!
AND IT TALKSI Did you know that the CoCo can produce incredibly realistic
digital speech without a special speech synthesizer? And I mean really
high quality speech! Forget the mechanical robot voice. This voice
quality is so good, it sounds human! Honest. Best of all, no extra
hardware is needed for speech. None. The CoCo produces this amazing
digital speech all by itself (with a wee bit of programming by Dr. Preble).
THOUGHTWARE — Next time your friends ask what your computer can do,
show them the Preble Thoughtwarei

*** Basic Freedom ***
for The Color Computer 3
(with versions for CoCo 1 & 2)
A Full Screen Editor for BASIC Programming
We call it EDITOR 3. Chris Babcock wrotea pure, efficient Machine Language
program to open a new dimension of ease and power for anyone typing in
a BASIC program.
Here are your BASIC Freedoms!
FULL CURSOR MOVEMENT — Use the arrow keys to move anywhere on a
screen. If you are using a Color Computer 3, then even the 40 or 80
column screen is supported!
INSERT, CHANGE or DELETE CHARACTERS anywhere on the
tijt screen. Simply move to what you wish to change, change
it and continue working!
LOWERCASE COMMANDS are OK! EDITOR 3 letsyou type in
lowercase any time or all the time. Lowercase command
words areautomatically translated to uppercase for BASIC.
Of course, lowercase text within quotes stays lowercase.
This is great when typing wiht the CoCo 3's 40 or80 column
mode with true lowercase!
MERGE LINES within a program with just a few keystrokes!
AUTO KEY REPEAT — Hold down any key and it will repeat.
INVISIBLE — Once EDITOR 3 has been loaded in, it is activated
V^- With a single keystroke! It hides itself out of the way of other programs
and can be turned off any any time. Pressing RESET will not hurt
EDITOR 3!
EASY TO USE — Installation takes seconds! Weil-written goof-proof manual
included.
COCO 1 & 2 — Yes, even though this program was conceived for the powers
of the new CoCo 3, we still support the previous Coior Computers. They
too, need their BASIC Freedom!
EDITOR 3 — So easy and handy, you'll never want to run your CoCo without
it!
Available on DISK only for CoCo 3 @ $29.95 + s/h
CoCo 1/2 version can not support 40 or 80 column screens. CoCo 1/2 version
is available on TAPE for $27.95 + s/h or DISK for $29.95 + s/h.
