BECOMING A MUNK?
Editor:
In response to Jarrod Hollinghead's high
score of 112,500 on Dunkey Munkey; I've
got a 16 year old member (Kevin
Hammerschmidt) of my congregation who
scored 172,500 and quit because it was
boring! I'm lucky if I break 70,000! Well,
back to writing sermons on Telewriter...

your contributions to it for your
scores in all the games available for

KUDOS
Editor:
Having very recently purchased a
Dragon-32, and surrounded myself with
many magazines, I came across an
advertisement for the Rainbow which is now
available here in England. On reading the
Rainbow 1 must admit that I went from a
mildly interested computerist to a very keen
trier and have subscribed for a regular
supply.
I am adamant about "getting on top" of
programming, but unfortunately at the
moment I cannot carry out the minor
adjustments necessary to make some of the
TRS-80 programs run on my Dragon. Do
you think you could include the minor
adjustments in your future issues?
I.C. Hawksworth
Derby, England
Editor's Note: The English Edition, as
opposed to the Edition in English, now
carries adjustments for the Dragon. We
felt this was necessary in order to take
care of the minor changes.
WANTS A POSTER
Editor:
As I have said before, in my opinion, there
is no other magazine comparable to yours. I
receive several magazines each month,
including Science Digest, Peterson's
Photographic, and others of a technical
nature. Of all of them, I look forward to
receiving yours most of all. I enjoy the
articles and the format is very well done.
In addition to being a high school science
teacher, I am also a semi-professional
photographer and framer. Needless to say, I
had the poster in the January issue matted
and framed and hung within 24 hours of
receiving the issue in the mail. I think it was
great. Mr. Crawford is truly talented as an
artist and January's cover readily confirms
this.
Please poll your readers as to the interest
in a poster of the January cover and any
future poster quality covers. I'm sure there
are many others like me who would love to
collect images of this fast growing way of
life.
I would also like to brag on one of your
advertisers. Recently I ordered 24 tapes with
boxes from Micro 80. In only a few short
days, 1 received them. Due to no fault of
theirs, eight of the boxes were broken during
shipment. I called them and they told me to
send them back for replacement. Not only
did they replace the eight broken ones, they
sent four more with them. Now, that's what I
call service. It's nice to know there are still
companies that believe in satisfying the
customer.
Thank you again for the wonderful job
you and your staff do each month.
Jimmie Bond
Minden, LA
Editor's Note: We've been thinking
about offering the January cover as a
poster, but the problem is we need some
sort of minimum order. If others are
interested in a poster at a cost of about
$5, please drop us a line.
TOM'S A WINNER, TOO
Editor:
1 was very pleased to learn when I arrived
home from vacation that my program
Escape From Sparta was selected as a
winner in your First Annual Adventure
Contest. The following day I bought a copy
of January's issue and was excited to see that
it had won Best Science Fiction Trophy. I
was, however, extremely disappointed to see
that the name of Thomas Hollerback, co-
writer of this adventure did not appear with
my own. Without his help I could not have
written Escape From Sparta. Escape From
Sparta was a joint effort and intended to be a
joint entry. Apparently, I may have mislead
you when I enclosed a separate letter in
reference to the game signed only by myself.
Tom's name appears along with my own in
the program heading. Please give Tom the
credit which he also deserves.

SIR GREGORY OF NEW YORK
Editor:
Thank you very much for the honor of
having my program, Sir Randolf of the
Moors, chosen to win first place in your
recent non-graphics contest.
Until recently, I have been going it alone
with my CoCo. Now I have a couple of
friends interested, and I can talk "shop" with
someone else besides my mirror.
I entered the contest not having any idea
that I would even come close to a mention
after the judging was completed. Thank you
for giving me a large boost of incentive.

OBJECTION
Editor:
These comments are to clarify statements
made in the January 1983 review of UP-1.
UP-1 is designed as an aid to program
development and not a peekerand poker. It
allows programs to be stacked in memory
until the memory is filled and has features
for correcting defective programs.
The review stated that UP-1 was written
for a 4K machine. This is not true. Obviously
more programs can be stacked in computers
with larger memory. Programs can also be
stacked in ROM Packs. It is true that the
memory maps differ slightly for BASIC,
Extended BASIC, and color disk systems.
Before program stacking can be
accomplished, the available free memory
must be determined. Although Extended
BASIC normally starts at 7681, programs
can be stacked starting at 1537 if the extra
graphic pages are not required. Programs
can be stacked in disk systems starting
around 4K. UP-1 can be stacked with a
defective disk program and UP-1 used to
correct the program.
UP-1 is not intended to replace the EB
Editor. Suppose statement 20 appears as
8223 between statements 10 and 30 in a
program. The Extended BASIC Editor
cannot correct this, but by using the memory
scan feature of UP-1, this error can be
spotted and corrected by poking the correct
values into the erroneous statement
number's vector location.
A machine language subroutine was
added to UP-1 which allows the operator to
switch and run another program by entering
EXEC M where M is the starting location of
the subroutine. This updated program was
sent to the Rainbow the first week in
January.

COCO COOKING
Editor:
When I'm finished with my computer in

out the dust. Wouldn't you know it, I left it
on until the next day and when I removed
the towel, it was cooking. But it still works

INFORMATION, PLEASE
Editor:
I am new to your magazine, and from
purchasing just one issue I am already set on
being a loyal reader from now on. I am the
owner of a TRS-80 Color Computer and I
have found more information in one issue of
yours than I have seen in all my previous
years as a TRS-80 owner. Your magazine
has truly expanded my views on the
capabilities of the CoCo. 1 recently
upgraded my 16K computer to 32K and I
would like to know if my computer is now
capable of playing all 32K games and
software. I thought perhaps I may have
some RAM limitations being that it was
originally a 16K computer. Keep up the
excellent work, you're truly a remarkable
magazine.

RECOMMENDED READING
Editor:
My thanks to Eugene Bouley of RI for his
recommendation (in the November
Rainbow) of Programming the 6809 by
Rodney Zaks and William Labiak. It's
everything he claimed!
Let me recommend another great book
for those who are really serious about
assembly language on the CoCo. The Facts
by Spectral Associates shows you wherejust
about everything is in the CoCo and how to
use it.

HELPFUL HINTS
Editor:
I think these letter to the editor sections
are great. I thought I would put my two cents
worth in.
If you own the Chess ROM Pack and a
black and white TV, you probably have
noticed that both sets of pieces appear the
same shade. Changing original memory
location SCODI to a $F0 or $F8 will remedy
the problem.
I would like to see more information on
disk drives.
Keep up the good work!

Playing Dungeon Adventure into the wee
hours of the night, I was rapidly gaining
confidence and had reached the 17th level. I
had defeated spiders, demons, wizards and
the like when I was surprised and destroyed
by a tiny bug. In my fatigued state, during a
battle I hit the "fight" key instead of the
"move" key. There being no one to fight I
was hopelessly trapped in an endless loop.
Undaunted, I resolved to rest and try
again. The next night, I was rapidlyjumping
levels and apparently jumped past level 20.
After continuing for some time, 1 was
attacked by 68 demons. That was when I
gave up and checked the listing for the
winning level and found it to be "=20."
Both of the above require only minor
fixes. To avoid the entry error in the fight
sequence, add this line:
1395 IFK$=CHR$(32)THENGOSUB
1440:GOTO1270
That will allow you to press the space bar if
you have hit the "fight" key instead of the
"move key" during the fighting sequence,
and return to the options.
By changing line 1910 to read:
1910 IFAL(1)= 20THEN2280
the program will not continue endlessly if
level 20 is passed. Nevertheless,
congratulations to Gregory Ricketts for an
excellent program and to Rainbow for their
choice.

Editor:
In Joseph Kolar's article "Let's Take
BASIC Training," he asked "Do you find
that your manual flops around and is
unwieldy and awkward to use, etc., etc.?"
His solution was to purchase another
manual to cut out the pages you are working
on, and save your original manual for
reference. Well, I came up with what I think
is a better solution. I purchased a music
stand to hold my books when I need to
program from them. It has worked out
super! I can adjust the height, and place the
stand at just the right angle so as to eliminate
that terrible neck pain you get from keeping
your head and neck bent down looking at
your work on the computer table.
Your Rainbow is F-a-n-t-a-s-t-i-c! Keep
up the good work, and please keep those
articles for us apprentices coming.
PRINT #-2,
I am beginning to get really excited about RAINBOWfest — which is, after
all, "CoCo's Very First Show!" As you will be able to see from information and
registration material in the Rainbow, it is to be in Chicago, April 22-24, at the
Regency-Hyatt Woodfield.
RAINBOWfest is going to be an all-purpose show — not just a trade
exhibition. Yes, there will be a lot of displays with people and products. And
most of the biggest names in the CoCo world will be on hand. You will see new
products, learn some new things and have a chance to talk with other CoCoists
from all over the country. We know of several groups planning to charter buses
for the trip.
But there is to be more to RAINBOWfest! One of the biggest things will be a
series of seminars and a breakfast talk. We have tentatively scheduled Don
Inman to be the breakfast speaker. And, as you know, Don is the acknowledged
master of cdmputer graphics for the CoCo. This breakfast is open to everyone,
so we hope you'll make plans to attend.
Then, too, the seminars will be run most of
the day Saturday, and on Sunday as well. All
the speakers and topics are not firm yet, but
we will be covering everything from Basic
hints to machine language animation, from
the legal rights you have as a buyer of
software to setting up and communicating
with bulletin boards. Also: A special session is
planned forofficersof Color Computer clubs.
All in all, we hope RAINBOWfest will be a
great weekend for anyone and everyone
interested in CoCo — on all levels, from
beginner to advanced programmer. If you can
possibly make it, we hope to see you there.
1 would like to thank everyone who has
taken the time to write in about the changes
we have been making to the Rainbow. The
one which has, obviously, received the most
attention is the "slick" paper. At this point,
the positive comments are running well ahead
of the negative ones — but there are a number
of you who have expressed unhappiness with
the new paper.
Those of you who are pleased with the "crisp," "neat," "professional" new
look of our magazine will be pleased to know that, at least for now, we are
keeping the "slick" paper. But, for those of you who have expressed
unhappiness, you, too, will be pleased to learn that we are making a slight change
soon that we hope will solve the most-mentioned problem — that of glare. We've
found another "slick" paper which has a slight bluish cast to it (it is hard to tell
unless the two papers are held up side-to-side). This paper will still give us the
same "slick" look, but should be a little easier on the eyes. As always, we will
appreciate your comments.
And, I suppose while commenting on the magazine in general, this is as good a
place as any to welcome Jerry McKiernan to our staff. Sally Nichols, our art
director, needed some help and Jerry is providing that as Assistant Art Director.
Incidentally, Jerry's a whiz at what 1 call "dot art" — and I'm sure you'll be able to
pick out some of his illustrations in this month's issue.
1 would also like to welcome Patty King as our first advertising and special
events manager. In addition to getting the advertising section in shape, Patty will
be responsible for RAINBOWfest planning— -and working with Dave Hooper,
who is the local arrangements chairman in Chicago. Patty is very qualified to
work on a project like this— she was responsible f or all the planning of the U.S.
Conference of Mayors in Louisville a coupie of years ago.
One of the things which has happened this past month is a couple of letters
flying back and forth from various people concerning a letter which' appeared in
the Bouquets And Brickbats section of last month's Rainbow about a product.
One of the letters was from Thomas Cassidy of Ozone Park, N.Y., in defense

Editor:
When anyone starts to learn/use
Assembly Lanugage for the 80Che/she will
soon run up against the terrible lack of
instructions on how to enter a line of
Assembly code. This is a simple stage,
almost a simple-minded one, but it is
essential and the lack of it can stop a learner
of Machine Language cold. In the book
Assembly Language Graphics for the TRS-
80 Color Computer by Don Inman and Kurt
Inman, the very simple first stages of data
entry are spelled out, explained, and
illustrated starting on page 49. Working
through this book would be a good idea
whether or not one wants to use Machine
Language/ Assembly Language graphics on
the 80C computer.

Editor:
In reply to Doug Tooms' letter (January),
Ghost Gobbler produces its sound by
storing data at location SFF20 very quickly,
as most machine language games do. The
printer port also uses this location as an
output to the printer. So, when sound is
produced, data (which comes out as
garbage) goes to the printer. The reason that
this garbage is only printed every once in a
while, is that the printer's buffer buffers the
garbage.
Here's something else that is not in the
documentation. When Ghost Gobbler asks
for your name, pressing SH1FT@ causes the
computer to go into high speed (providing,
of course, that your CoCo works with the
"high-speed POKE').
To Jorge Mir who wanted to move his
string space to the extra 8K of his 64K
system: Try POKEmg the highest address of
your extra memory (which I believe is
SFEFF) into the low memory locations
$27/ 28. Be careful not to use more than 8K
of strings or you might run over Disk
BASIC.

Now, I have a question. How is SLENB*

We have just become acquainted with
your magazine — having the November and
December issues. Find them great!
I keyed in Parachute Jump from the
December issue and now have a battle on my
hands. Our son (1 1 years old) has beaten his
father's score and, of course, that can't go
unchallenged. 1 think they play it just to see
the lightning bolt and to hear the tune being
played as the poor chutist drops to ground

Cameron Amick obviously spends a
great deal of his computer time as a
gamer, and since he has gone to the
additional trouble of logging his scores
and mailing them to us, we thought we
would print them. His Dunkey Munkey
score of 300,000 points lands him in
fifth place on this month's Scoreboard
for that game. As his other scores are
uncontested, we suppose that gives him
at least a temporary first

Roll Those Bones
(And Other Characteristics)
By Bob Albrecht and George Firedrake
Rainbow Contributing Editors
Last time, we showed you three short programs to "roll"
the seven basic characteristics for a fantasy role playing
character. Here is one of the programs.
_100 REM ** CREATE A CHARACTER
199 : •
300 REM ** CLEAR THE SCREEN

550 GOTO 510
560 DATA STR, CON, SIZ, INT
570 DATA POM, DEX, CHA, ZZZ
599 :
700 REM ** TELL HOW TO DO AGAIN
710 PRINT
720 PRINT "TO DO AGAIN, PRESS AN
Y KEY"
730 IF INKEY* = "" THEN 730 ELSE
310
799 :
900 REM ** DICE SUBROUTINE
910 Dl = RND (6)
920 D2 = RND (6)
930 D3 = RND (6)
940 DICE = Dl +
950 RETURN
D2 + D3
Our program rolls a number from three to 1 8 for each and
every characteristic. Alas, a character with SIZ 15, STR 3,
and DEX 5 will never make it in the GameMaster's world.
So, we suggest some alternative DICE subroutines.
Our first variation. Roll 3D6. If DICE is less than 6,
assign 6 as the value.
900 REM ** DICE SUBROUTINE
910 Dl = RND <6>
920 D2 = RND (6)
930 D3 = RND < 6 )
940 DICE - Dl + D2 + D3
950 IF DICE<6 THEN DICE=6
960 RETURN
7. V
Our second variation: A more generous GM says, "If
DICE is less than 6, add 3 to the value of DICE."
900 REM ** DICE SUBROUTINE
910 Dl = RND (6)
920 D2 = RND < 6 )
930 D3 = RND (6)
940 DICE = Dl + D2 + D3
950 IF DICE<6 THEN DICE=DICE+3
960 RETURN
We hear some GMs allow players to roll 4D6 and take the
best three. If you roll /^r_
you can discard
and take
=5T
^71
for a total of 1 3
Hmmm...we get the same result if we add all four dice and
subtract the smallest. Here is our first attempt.
900 REM ** DICE SUBROUTINE
910 Dl = RND (6)
920 D2 = RND (6)
930 D3 « RND < 6 )
940 D4 - RND (6)
950 SMALL - 7
960 IF Dl< SMALL THEN SMALL-D1
970 IF D2< SMALL THEN SMALL-D2
980 IF D3< SMALL THEN SMALL-D3
990 IF D4< SMALL THEN SMALL-D4
1000 DICE=D1+D2+D3+D4-SMALL
1010 RETURN
Here is another way, using subscripted variables.
900 REM ** DICE SUBROUTINE
910 FOR KK=1 TO 4
920 : D (KK) = RND (6)
930 NEXT KK
940 SMALL - 7
950 FOR KK=1 TO 4
12
the RAINBOW March, 1983
960 : IF D (KKX SMALL THEN SMALL"
D(KK)
970 NEXT KK
980 DICE-D(1)+D(2)+D<3)+D<4)-SMA
LL
990 RETURN
We suggest a third way for you to try. Write lines 910
through 930 as we did above, putting the tour dice values in
D(l), D(2), D(3), and D(4). Next, sort these values so the
smallest value is in D(4) and the other three values are in
D( I ), D(2), and D(3). Finally, compute: DICE = D( I ) + D(2)
+ D(3).
Our program rolls seven basic characteristics for a Worlds
of Wonder or Runequest character. For a Dungeons &
Dragons or Tunnels & Trolls character, change only lines
560 and 570.
D&p Character: 560 DATA STR, INT, WIS
570 DATA DEX, CON, CHR,
zzz
T&T Character: 560 DATA STR, CON, IQ

Lines 1010 through 1070 are a data file. This file consists
of seven records. Each record consists of a character's name
followed by seven numbers. For instance:
1030 DATA BRIDLA, 11, 12, 10, 15, 6, II, 16
Name Seven numbers
The last record, which begins with ENDFILE, is not an
actual character record. Instead, it is an end-oj '-file (EOF)
record. If you enter a name that is not in the file, the CoCo
will search in vain and arrive at EN DF1 LE. It will then print
I DON'T KNOW followed by the name you entered. This
will also happen if you misspell a name that is in the file, or
even if you ask it for ENDFILE.

You can change these records to records for your

statement.
Your turn. Write a program to display the entire file, one
record at a time, beginning with the first record. To get the
next record, press the space bar.
What happens when you tell the computer to compute a
random number of a random number? For instance,
suppose you tell the CoCo to compute:
RND(RND(2))
H ieronymus Heuristicus wrote a program to find out. His
program counts how many ones and how many twos
occurred in a sample of RND(R ND(2)) numbers.
"Well, an RND number is an RND number," thought H.
H. as he typed RUN. "I'll get about the same number of ones
and twos." But here is what actually happened.

Color Graphics
By Lane Lester, Ph.D.
Breathes there a CoCoNut with soul so dead,
Who never in his heart of hearts has said,
"Oh, how I wish I could make color copy
Of that display on my color TV!"?
The dim recesses of my mind which produced shreds of
the poem that stimulated the couplet above just will not
produce the author's name so that 1 can apologize to him. As
tragic a blow as my efforts may be to the world of literature 1
am sure that the poem does indeed express a feeling that
many of us have had. Imagine my delight when Francis
Kalinowski published "Printer Color Art" in the September
1982 issue of 80 Micro which showed howto make beautiful
multi-colored pictures on the Epson MX-80. Because you're
probably not as lazy as 1 am you can't imagine my
disappointment when 1 realized how much programming
would be involved to produce each picture. Sadly 1 setaside
the tools that Francis generously provided and went on to
less-demanding tasks.
But now the light has dawned again! Using programs
provided for us by two giants of the CoCo world it is
possible for indolent folks like me to have beautiful
reproductions of screen graphics. Arnold Pouch, now
deceased, developed Motion Picture Programming based
on a drawer program in the August 1981 issue of
Chromasette. This powerful technique which Arnold
described in the March and April 1982 issues of the
Rainbow makes the creation of graphic displays a pleasure.
A complete set of programs and a tutorial are available from
Superior Graphic Software, or you can buy the
Chromasette and use the Rainbow articles to make the
changes to M PP. Making printer copies of MP P graphics is
a snap with the Graphic Screen Print Program (GSPR) sold
by Mel Hefter of Custom Software Engineering. Versions of
this program are available for most of the popular printers.
While this means that anyone can at least have black-and-
white screen prints, the availability of colored ribbons will
determine whether color prints are possible. Colored
ribbons for a number of printers are available from Check-
Mate and from B.T. Enterprises. A list of suppliers'
addresses is given at the end of this article.
The illustrations that accompany this article demonstrate
the results you can expect. The jack-o-lantern came from a
program 1 wrote to run Halloween night with the TV in our
bay window. It was done in PMODE I which gave me four
different graphics which could be switched and provided
Jack with the ability to blink, wink, and "talk." The giraffe
was done by projecting a 35mm slide on the wall and tracing
it onto a clear plastic sheet. This sheet was taped to the
television screen, and then the MPP program was used to
create the graphic. In PMODE3, one graphic has the eyes
open and the other, closed. A formula using RND provides
a very natural blinking of the eyes. If you've had a biology
course recently enough you may realize that the picture with
the blue blobs represents the electron transport system. This
is f rom an M PP animated graphic series in PM ODE 1 that I
use to illustrate one of my biology lectures. The three-color
graph illustration was produced by a graphing program 1
published in the March 1982 issue of Color Computer News.
The lettering on the graph was done with another program
available form Custom Software Engineering, Alpha-Draw,
which can be added to any graphic program.
"Enough," you say, "I'm sold. Now how can 1 makecolor
prints of graphic screen displays?" In addition to the
appropriate hardware and supplies, youfirstneedtogetand
learn to use the MPP program. I'm going to assume you've
done that in thefollowingdiscussion. TheGSPR program is
in machine language and comes with instructionsforediting
Basic programs such as MPP so that they will load and
execute GSPR. In addition to those changes I added to line
22 of MPP an "L" option which GOSUBs to "330
X=USRI(0):RETURN", executing the screen print.
Although typical screen graphics have several colors, they
must be altered considerably in order to produce color
18 the RAINBOW March, 1983
printsi, This is necessary because each color requires a
separate pass through the printer with a different ribbon in
place. For each color in the print, that part of the screen
display is changed to red (simple with MPP) which with
GSPR gives the densest printing. The rest of the graphic is
erased to green which is unprinted. In your original graphic
program you may use the eight pages of graphic RAM for
animation, but for the screen print you can use them for
multiple copies of the graphic. In PMODE 1 you could store
four different versions, one for each of four colored ribbons.
If you are using more than four colors or a higher PMODE,
you would make separate saves of the graphics which with
MPP is rapid (at least with disk) and convenient.

In order that the different colors will be properly located
on the paper, accurate re-positioning of the paper for each
pass is critical. This should be quite easy with most printers.
On the Epson, just to the right of tlie left tractor lock, is a
black horizontal ridge which serves as an index. The brand
of paper 1 use is numbered along the left perforated strip and
after each run 1 return the paper to the same number. If your
paper is not numbered or your printer does not have an
index, Francis Kalinowski, in his 80 Micro article, suggests
placing a piece of paper tape at the edge of the tractor. Then
you can make a pencil mark across the tape and onto the
paper to use as a guide. So that with each run the paper will
have the same tension, 1 rewind past the number and then
return. Francis suggests an even more preciseapproach, and
if you run into problems you might want to consult his
article. He does make twovery worthwhile suggestions, that
you use 20- pound white bond paper and that you unlock one
of the pin-feed mechanisms to prevent paper buckling. To
give a greater depth of color for publication, 1 ran the paper
through twice for each color, but generally this is not
necessary.

Software Review...
Wall Street Touted
As Good Investment
I suppose that in the back of the minds of many of us is the
dream of someday making a killing in the stock market, or
watching a handful of dollar bills multiply into hundreds of
thousands of bucks, of Swiss bank accounts, and of having
the problem of figuring out how we're going to spend so
much money. The reality for most of us, however, is that
those few extra dollars are hard to find for us to get started
on the road to riches.
Part of the beauty of Wall Street is that Valhalla
Enterprises has been generous enough to provide each of us
with $1 .000 to get started. The rest is up to the indiv idual and
how he or she takes advantage of all the helpful information,
such as stock and market histories and general trends that
are part of the game. Individual hunches also are important,
of course.
A couple of bars of "We're I n The Money!"at the opening
put us in an optimistic mood for what is a challenging,
fascinating and colorful game. I would think that even those
sleepy-looking elderly chaps who spend their lunch hours
daily watching the big board would be caught up in this
game.
Tailored for one to four players, Wall Street first asks for
the names of the participants. The group is then asked for
the amount of earnings that will determine the winner (if you
want to play to $3,000. enter "3.000"). Actually. $3,000 is a
short game for two people, taking between 10 and 20
minutes, depending upon their skill and luck. A $10,000
game probably will take four people about an hour if they
move along at a good pace.
The stock exhange screen gives you the current price for
eight stocks:
Utilities — Energetic Electric, Wishwashy Water;
Blue Chips — Mammoth Motors, Stupendous Steel;
Glamors Calculating Computers. Albatross Aircraft;
High Risk — Pinchpenny Prospecting. Risky Research.
The current month is displayed in the upper righthand
corner. The condition of the overall market is also shown
(up, down or even). At the bottom of the screen is a list of
possible actons: Pressing "P" lets you see your account
along with your holdings and disposable income: the "S"
key gives you stock history graphs, and "M" displays the
market history.
An individual player's screen gives you the options of
buying or selling. If you press "B" you are asked "Which
Stock'.'" Typing the initial of the stock then gives you the
history of that company's trends. A similar procedure is
followed if you're selling.
After the round (or "month") of transactions is
completed, be ready for some surprises because, just as in
the real world, the stock market reacts to many otherevents,
such as labor strikes and rumors of war. Then, of course,
there arc pleasant surprises, such as big dividends and 2-for-
1 or 4-for- 1 stock splits. You can just imagine the floor of the
New York Stock Exchange when such excitement occurs.
Wall Street is an excellent game for teaching the ins and
outs of the stock market, as well as the patience and
knowledge required to give investments the opportunity to
grow. It's also a good game to demonstrate CoCo's
versatility. Warning: Like CoCo, the game also is
contagious, and you should prepare yourself for hours of
fun. Wall Street is a great investment!

Hardware Review...
This Keyboard Is A
Good Quality Product
We were a little concerned when the Professional
Keyboard arrived with one page of documentation
consisting of four short lines explaining how to install it.
After all, something as complicated as replacing a keyboard
should have all sorts of information, right?
Not to worry. Because the keyboard on the Color
Computer is connected very simply, the installation was as
easy as it looked. Total time was seven minutes, and some of
that was due to the fact that we lost one of the screws to
reattach the cover to CoCo.
Once in place, what we had, essentially, was a Model I
keyboard in a Color Computer case. The fit was perfect. The
touch was good and there were no real problems. As of this
writing, the Professional Keyboard has been installed for
the better part of three weeks with no trouble whatsoever.
It takes a bit of getting used to. But, if you are one of those
people who is unhappy with the flat Color Computer
keyboard, this product is a real gem.
The keys, of course, are higher than those for the Color
Computer. And the ENTER key is located at a slightly
different place. That took a little getting used to — but the
touch-typists around have taken to the Professional
Keyboard much like the proverbial duck to water.
It also has four function keys. U nfortunately, there is no
documentation to tell you how to use them. We hope an
addenda to the instructions will be forthcoming. And, of
minor concern, it is obvious that keyboard overlays for
some products such as the Platinum Worksaver, Master
Control and Basic Aid will not fit this new keyboard. A
small price to pay if you want to replace your keyboard.
We have heard more complaints about the Color
Computer's keyboard than anything else. For those of you
who do not like it, the Professional Keyboard offers an
excellent alternative that is well put together and works
without any problem.
You may notice that we refer to the "Color Computer"
thoughout this review. The reason is that the Professional
Keyboard, as of this writing, is not available for the TDP-
100, nor for Color Computers with an "F" revision board.
We understand, however, that one is in the works.

THE SOLUTION AND WHY WE BUILT IT
When we first introduced FLEX for the CoCo In February
1982 we received hundreds of calls from software and hard-
ware developers who wanted to use the CoCo because it
was so inexpensive compared to everything else on the
market. Howeverthere is not enough expansion or I/O In the
CoCo to make this possible for most of these users, i know
that the CoCo is viable In most cases, but for many, there
needed to be more. So that was the original reason for
designing the expansion box we call "THE SOLUTION."
The motherboard has the 2K/4K EPROM socket with a 4K
monitor EPROM in it. Also inside are 4 vertical connectors
for internally mounted boards or ROM type cartridges. The
fifth connector Is horizontal and is made for the disk con-
troller, ROM cartridges or additional expansion out the side
the of The Solution. A four position dip switch allows for 3
options to be selected. One option will cause the CoCo to
get its interrupt and reset vectors from the monitor Instead
of RS Basic.
if you choose to come up in the monitor, then it is not
necessary to have RS Extended Basic in the CoCo to boot
FLEX because the monitor has a built-in boot. This saves
$100.00 of the cost of The Solution. The power supply is e
plug-in-the-waii type with a connector In the back of the
case. The back of the case is open and it is thru this that all
the cables for the different cards go. This makes for a very
neat appearance.
TECHNICAL SPECIFICATIONS
Bus Structure... Fully buffered Color Computer compatible
bus. Priority daisy chained arrangement where each slot has
a priority assigned to it. The farther out on the bus that you
are, the less priority you have. The disk slot (0) has the
highest priority with slot 1. 2, 3, and then 4 has the lowest.
The pinout and the timing is the same as the Color Com-
puters with the exception of the sound line. This is used on
the motherboard for the priority line.
Power Supply...The power supply Is a tracking power sup-
ply which means that the Color Computer itself turns The
Solution on and off so that there is no need for an on/off
switch. A LED on the front of The Solution Indicates when
the entire system Is on or off. The tracking power supply
means that The Solution's bus voltage will be the same as
the Color Computers to within a very few mlnnlvolts. The
power supply included with The Solution Is a 1 amp supply
for the 5 volt line only. The + 12 and - 1 2 voltages are taken
from the Color Computer.
Dip switch options...
1) Select the 4K ROM monitor. When this option is
selected, the system will come up in the monitor and get in-
terrupt vectors from it rather than the Radio Shack Basic
ROM. The reason you might want to do this Is so you can
boot FLEX from the monitor rather than Basic. This will
allow running FLEX without have to have Extended Color
Basic in the CoCo. This also ties in with the option on the
serial card to come up on a terminal instead of the CoCo TV
set and keyboard.
2) Disable the disk slot (0). This will allow using ROM
cartidges In The Solution without unplugging the disk card.
When the switch Is on, the ROM is active. When It is off,
whatever ROM cartridge is there is active. This infers that
you could switch back and forth between a cartridge and the
disk system. This is NOT necessarily true because of the
need to initialize the disk software in the ROM and this may
destroy what is in memory, it may be possible under special
circumstances to do this but it is up to the user to work it
out.
3) Select either a 2K or a 4K EPROM. This is set for a 4K
EPROM which Is included with The Solution. However, it can
be changed if you have a need. The EPROM is addressed at
SE000.
4) User definable. This means that we didn't use this
switch for anything, but you can if you want, or wecouidcall
It 'reserv ed for future expansion.' This means that we don't
have any use for it now, but we may in the future.
The Solution I/O cards are addressed at either the $FF60-
SFFBF area OR the $FE00-$FEFF area.

EDUCATION
The Forgotten Aspect
Of the Classroom Computer
By Dr. Paul Kimmelman
Assistant Superintendent
Norton (Ohio) City Schools
Educators are being inundated daily with advertisements
from a whole host of computer dealers. These dealers
include: computer hardware specialists, software specialists,
and many resource book companies. Unfortunately, while
educational computer purchasers are seriously reviewing
computer hardware, software, and resource materials, an
important aspect of future computer implementation is
being forgotten — that is, what will the computers and
peripheral equipment be placed on? Where will programs be
stored'.' It should be noted that this may not be a major
problem for schools at this time; however, individual
classroom computers will more than likely eventually
become part of a computer lab an(i furniture will be an
important aspect of the design in the lab.
One company, Gusdorf Electronics Furniture, has
designed a line of furniture that will more than meet the
needs of public schools. In addition, Gusdorf has priced its
equipment very reasonably considering some of the major
advantages that it offers over several other comparably
priced companies' products.
There is little doubt that computer furniture has not been
given much thought while educators have been pressing to
expand their hardware and software inventories. With
equipment prices falling, however, we must begin to look at
furniture as part of the plan to implement computer classes
in school districts. The Gusdorf line will meet those needs
through its carefully planned expandability options for a
variety of classroom designs.
First, Gusdorf furniture is carefully packaged in order to
prevent damage while being shipped. Once uncrated, the
directions for assembly are written so that even the novice
mechanic could put it together. What is even better is that
assembly takes less than thirty minutes.
For schools, the design and appearance of the furniture
are a major advantage. All of the furniture has a Paradise
Hickory veneer which is very attractive. The wood panels
which are primarily Appalachian Poplar will resist warping,
splitting or cracking and are veneered with a heavy-gaUge
vinyl grain finish.
Table tops are made of formica which will also prevent
scratches and marring. This is extremely critical for school
use since students will often use the desks for writing as well.
Self-adhesive rubber accessories are packaged with
Gusdorf furniture to combine wires and, attach them to the
back of the furniture. This is a convenience accessory in that
it prevents many wires from merely dangling in the back of
the furniture.
Storage is an exceptional component of the computer
furniture line. For example, under the hutch desk unit is a
shelf which can house the many notebooks, disks, cassettes,
and manuals that the user wants to keep out of the way but
easily accessible.
The hutch desk is spacious and designed to handle a
complete computer set-up. For the Color Computer user,
the hutch desk would enable the userto house the keyboard,
monitor, and a cassette or two disk drives on it. In addition,
a modem could be easily added on the top shelf next to the
monitor.
For those desiring expanded furniture options, Gusdorf
includes a credenza unit, printer stand, corner pieces, and
expanders — all which can be attached to each other. These
accessories all provide more work space and storage.
Now for one of the highlights of the Gusdorf line — prices.
A computer hutch desk sells for approximately $170. The
expanding units such as the credenza sells for $270. A
printer stand is $140, and expanding table units run from
$40 to $80. These prices are more than likely discounted by
local dealers.
All of the Gusdorf furniture is sturdy and designed to
support the equipment placed on it. One of the brochures
from Gusdorf shows a monitor and printer on the top
portion of the hutch while a keyboard and two disk drives
are stored on the desk unit. Each of the assembly holes is
reinforced to prevent excessive wear and tear.
Computer purchasers for schools will have to begin
looking at computer labs for the future of computers in the
curriculum. The Gusdorf line is certainly, at this time, the
best answer to an attractive computer Jab.
There are two suggestions for the Gusdorf designers that
would help computer users. One would be to put a drawer in
the desk unit, and two, allowforanoptiopof wheels on all of
the furniture instead of flat gliders.
In conclusion the main criteria for computer furniture,
design, appearance, storage, expandability, and pricing
have all been addressed by Gusdorf. There is no question but
that furniture has become the forgotten portion of a
computer plan, but through the new Gusdorf line we can all
begin planning for when all of our Color Computers in the
schools will be moved to a laboratory environment. In
addition, home Color users will find that the Gusdorf
Compu-Table can house almost all of the necessary
equipment in a very small space and in a convenient manner.

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. We're
much more interested 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 makingsubmissions, please send a SASEto:

TWO ILLUSIONS
Optical Illusions
By D. and R. Delbourgo
The eye is easily deceived. Psychologists will tell you that
our perception of shape is noticeably influenced by the
geometry and character of the surroundings: nowhere is this
more apparent than in the most famous optical illusions.
The listing below contains a number of such illusions
(except for the checkered spirals and endless stairs) f oryour
amusement. The CoCo can score over the textbook
demonstrations in that the shapes can be presented
alternately, with and without perturbation from the
surrounds. Because highest resolution is essential, this
means that all graphics pages are used up, and
unfortunately, this leaves little room forthe program itself.
In spite of severe compression we have been incapable of
squeezing all the material into 1 6K, but 32K is well and truly
ample. Therefore, for those of you with I6K machines, we
suggest that you delete lines 47-70, 80-82, and lines 10, 1 8-22
from the total listing and call this your first program. Then
(from the whole listing again) delete lines 13-17, 24-46 and 3-
7, 76-79 and call this your second program.
See how well your eyes stand up to the tests and
experiment with the programs by shifting and distortingthe
basic shapes relative to their settings — another piece of
flexibility that comes by courtesy of the TRS-80C.

Optical 2
By Norman Latner
Optical illusions are always fascinating. First you see it
one way and then another, or your eye is led to a seemingly
impossible situation. Both of these effects appear in this
graphics program which I call Optical 2. I'm sure you'll
enjoy looking at them and listening to the Mozart selection
which accompanies the first illusion. P Mode 4 graphics are
used to give smooth diagonals, while the black/white color
set with red/ blue "fringing" add to the clean, crisp visual
look.
The program breaks down in the following way. Lines 10
to 80 display the title, with alternating colors and sound.
Line 90 sets the mode to 4, the screen to I, I and clears the
graphics screen. The first illusion is drawn in lines 1 00 to 240
using the LINE instruction throughout. The music, in lines
250 to 420, is assembled in the form of strings, so that
musical phrases can be easily repeated using the PLAY
command. This section also contains two PAINT lines
which change the background from black to white for
another interesting visual effect. Finally, lines 430 to 5I0
draw the second illusion, again using the LINE instruction.
If you're like me, you may be a little reluctant to key in a
program unless you know it's worth the effort. Although I
can't give you any guarantees, the program is structured
such that you can enter it in sections. The minimum entry
would be lines 90 to 240 which will display the first illusion
with a black background. You will have to add a temporary
line: 245 GO TO 245. This prevents a return to the text
screen. If you like what you see, add lines 430 to 5 10 for the
second illusion. Line 245 should now be changed to: 245
FOR T = I TO 2500: NEXTT. This holds the first picture on
the screen for a few seconds. To complete the program from
this point, just add the missing lines, delete line 245 and
enjoy.

half-life
demonstration of
nuclear decay
By David C.
The concepj^of half-life is widely taught in several fields of
physical science. It is used to explain the rate at which
various unstable atomic nuclei decay or change by emitting
particles and energy and are thus transformed into different
nuclei. For example, uranium 238 is unstable and changes
through nuclear decay into lead. Not all of the original
nuclei change at once, however. In fact, this is far from what
actually happens. The decay of any individual unstable
nuclei is a random event, and thus impossible to predict with
any degree of accuracy. In the case of uranium 238 , we do
know that it takes 4.5 x 10 9 years for one-half of the nuclei
to decay to become lead. After another 4.5 x 10 9 years,
one-half of the remaining uranium 238 nuclei decay and
after a third interval of 4.5 x 10 9 years, another one-half of
the uranium 238 nuclei decay and so on. Therefore, the time
interval in which one-half of a sample of unstable atomic
nuclei decays is called the half-life. Each type of radioactive
substance has its own half-life which can vary from a
fraction of a second to billions of years.
This program for the Color Computer illustrates the
random process of nuclear decay and shows how, through a
random process, the half-life comes to be. Initially, 144 blue
rectangles are set on the screen, using the low resolution set-
reset procedure. Extended Basic's TIMER function is used
as a time counter. Each blue dot (rectangle) represents an
unstable atomic nuclei of a particular imaginary element.
The X and Y coordinates of each dot are stored in arrays.
The computer then looks at each point individually and
through the RND function decides whether or not the nuclei
will decay. If it does decay, then the dot is changed to red.
When one-half of the nuclei have decayed, 72 in this case,
then the half-life interval is displayed. When half of the
remaining nuclei decay, the second half-life time is shown,
and so on, up to the fourth half-life.
When the program is RUN, you are asked to IN PUT a
time factor. This can be a number from 2 to about 30. Higher
numbers may cause the TIMER to reset. A small number
produces a shorter half-life period.
The first number displayed at the right of the screen is
identified as the half-life and the subsequent displays are
labeled second, third and fourth half-life. These are
cumulative timer values and should be even multiples of the
half-life (two times, three times and four times). The first
half-life is displayed when 72 nuclei decay, the second when
36 more decay, the third when 1 8 more decay and the fourth
when nine more decay.
Since 144 points do not represent a truly large sample size,
the results do not always give half-life periods that are the
Lengyel
same. For example, if the first half-life is at 250 counts
(about 25 seconds) then the second should be at 500, the
third at 750 and the fourth at 1000. The actual results will
vary but do come close enough. Actually, the variability can
lead to some interestingclassroomdiscussions on the idea of
random events.

program size, which granules are used, and the start, end, and
execute addresses for machine language programs. It will
also print a menu on the screen for a disk in the drive, and
when you indicate yourchoice it will load and either RUN or
EXEC the program for you as appropriate. In addition, it codes
your files by DATE, and it codes your disks by NAME and
NUMBER. And, it creates and maintains a file of all yourdisks
(and the programs on them) which you can sort and print as
needed. You can sort a collection of up to 300 disks. Could
you use a printed list of EVERY program in your collection, in
alphabetical order? This list tells you which disk has the
program you need so you can find it easily, and all this is only
the beginning. There are so many features we have no space
to mention them all. Both the 16K and 32K versions are
included, and we suggest you place a copy of the program on
every diskette for quick access. You will wonder how you got
along without this beauty!! Full, easy to follow instructions.

Software Review...
Homebase: Complex,
Versatile Data Management
By Frank J. Esser
The purpose of a database program, or system, is to
provide a means to store data in such a manner that the user
of the system is not required to know where or how the data
is stored. His only concern is that indeed it is stored. To this
end, many database systems have been written f orlargeand
small computers. Some are easy to use, some are hard to use
and then there are some that are downright painful to use.
Homebase is a program which has been designed to serve as
both a database manager and a text/word processor.
Homebase is written for a 32K Color Computer with
Extended BASIC and a disk operating system. The
programs are set up to handle the characteristics of either
Radio Shack LP V 1 1 / LPV 1 1 1 or Epson printers. 1 have a
Radio Shack LPV11 printer and experienced no trouble
with it at all.
The entire Homebase system comes enclosed in a three-
ring binder. The documentation is subdivided by functions
with each of the system menus receiving its own divided
section. The documentation is clearly laid out and easy to
read. The diskette is enclosed in a pocket, specifically
designed for this purpose, inside the front cover. Also
enclosed is a separate seven-page document which gives a
brief overview of the system and the best manner with which
to become familiar with it. The documentation was
produced on a matrix printer with free use made of the

elongated print and overstrike features. The entire package
is very nicely done and is impressive in its format. There are
three examples in the first chapter which are designed to
help the new user become familiar with the programs. The
programs are not hard to use once one becomes familiar
with them. But because of the complexity of the operations
and the interaction of the commands, it does require a
considerable amount of experimentation before one feels
comfortable enough to start serious data entry. This degree
of experimentation is not unusual for a program of this type.
If you are looking for a program you can setup and start
entering data into the same day, this is not the one for you.
But, if you want a program that will give you the option of
user-defined file parameters, report formatting at the time
the report is generated, searches through the data base on
file defined items, by value, and do not want to worry about
excessive disk accesses because you are expanding a
sequential file, then this is the program for you. The
examples provide a good start, but are lacking in a good
explanation of the interaction of the commands used in
them. Good documentation is ever so important. It is the
communication link between the producer and the user and
needs to be clear and to the point. 1 found the
documentation package with Homebase to be lacking in
only one aspect. On those pages where many options were
described, it would have improved the readability if a black
line was inserted between each of the option descriptions.
The system is broken down into two distinct sections: the
text/ word processor section and the database section. 1 will
cover each section individually. The system as a whole leaves
something to be desired. It requires that, once the program is
run and exited, it cannot be rerun without recycling power. I
am hard pressed to determine why a program has to be
designed with such constraints. 1 tried running several of my
standard programs and routines after running Homebase
and all appeared to be in order. But just the warning leaves
me with an uncomfortable feeling. I have many years of
experience with computer systems in the hardware/ sof tware
field. One of the major causes of system failures, even in this
age of integrated circuits, is unnecessary power cycling. It
bothers me when a program is written in a manner that the
system is left in such a state that power must be cycled to
restore it to a fully usable condition.
The text processingsection is menu driven, as is the whole
system. The text processor builds a text file by forming a
group of not more than 250 text records. Each record may
consist of a maximum of 480 characters, 15 lines at 32
characters per line. Each record block is given a name. It is
through this name that the blocks can be later recalled. The
record block parameters are specified at the time the file is
created and are stored with the file for future reference.
The processing functions available offer all the general
utilities such as adding, deleting, updating and displaying
the records. During the building of a record block,
compressed, double width, overstrike, and emphasized
printer control codes are available as imbedded characters
in the text. The format codes are generated by single key
commands and are very easy to use. Also available are new
line, new page, stop printing and tab sets. The important
point lo remember here is that all processing is done at the
record block level. You can put a document together in any
manner you choose by simply manipulating the record
blocks. Individual blocks can be selected, reordered,
changed or sorted before printing. All of this can be done
without affecting the data stored on disk. Suppose that you
wanted to print a document that would consist of record
blocks one and five. Using the "select" function, record
blocks one and five are collected. Then using the PRINT

command, they are printed. You then have the option to
discard those blocks just manipulated and start all over
again. Or you can add more records to those already selected
and repeat the entire process. There are some disadvantages
to performing text processing in this manner. If you are
familiar with a standard text/word processor, then beware,
because Homebase does not function in the same manner.
Perhaps its biggest drawback is its apparent inability to
properly format on the screen how an actual page will look
when printed. The program handles upper/ lower case in a
manner identical to BASIC. That is, lower case characters
are represented by reverse video. Homebase will create
documents of good quality if you are willing to spend the
time required to manually format the separate record
blocks. There exists what 1 consider a serious flaw in the
printing function. The printing process allows the user to set
the right margin. The manual does spell out the rules for
handling the right margin. When the right margin is
encountered, a new line is started when the word being
processed ends. If the word is longer than the document
width, then the word is broken and the remainder is carried
forward to the next line. The more expensive word
processors generally handle this problem by doing a look
ahead. If any part of the last word in the present line lies on
the right margin it will insert enough double spaces into the
line to cause the end of the preceding word to be in the last
column. For those printers with proportional spacing, the
word processor will adjust the spaces evenly between the
words on that line to get the same effect. Some of the less
expensive word processors will simply pick up the entire
word and carry it forward to the next line. This leaves a more
ragged edge, but the document is clearly readable.
Homebase only has this problem when the right margin is
specified to close to the actual form width. Another minor

problem occurs when the print option is exercised and the
printer head is not at the home position. It seems that a
carriage return (cr) is not sent to the printer prior to the
printing of the first record, thus the first line is started
wherever the print head was last used and that may not be
the left margin. The text processor does perform as
advertised and will produce good documentation if you are
willing to spend the time required to do so. After years of
using a word processor, I do not feel Homebase is a good
substitute.
The database section of Homebase is menu driven as are
all elements of the system. For those of you who are not
familiar with database managers, I would like to offer a brief
explanation of how they function. A database system stores
data in a record/field structure, the primary data structure
being the file. The secondary structure is the record/field
pair. The most commonly used example to explain this
relationship is a file cabinet containing sales invoices. The
file cabinet is equivalent to the disk file. Each sales invoice in
the file is equivalent to a record in the database file. Each
separate entity on the sales invoice corresponds to a field in
the database record. The customer's name and address
could be a field as well as the date, the type and number of
items sold. Each record in the database has a name attached
to it. In the case of our file cabinet, the customer's last name
could become the record name and correspond to a file
folder in the cabinet. Seem confusing? Well, the first couple
of times around it will be, but don't let it scare you. If I can
learn it, anyone can. Now with this information in hand, let's
proceed. Homebase allows for the definition of 50 fields in
each record and a maximum of 2 50 records per file. The type
of definitions which are allowed are:
A) Amount, treated as a dollar amount
C) Code, can consist of any five characters
I ) Identification, consists of nine place integer
O) Other, is a nine digit decimal with two digit decimal
places
D) Date, consists of month/day/year
P) Phone, consists of area code plus seven-digit phone
number
T) Time, consists of time of day in hours/minutes
The definition of data fields and the actual entry of data
are easily mastered if you are familiar with the basic
concepts. The real challenge to using a program of this type
is to lay out the data fields in such a manner that the data can
be easily obtained and used. 1 have maintained a list of
software/hardware/games reviews pertaining to CoCo
which have appeared in various publications. The list is
getting quite long and hard to manage. Thus, I decided to see
if I could get Homebase to handle this mass for me. It
required about 3 0 minutes to decide just what fields I wanted
to include. The creation of the data file required another 10
minutes. I was ablet o enter the da taat a pretty good clip due
to the excellent screens used during this process. Once the
data was in, I started processing it according to hardware,
software, type of software review, and the magazine it was
in. I was surprised at the ease with which 1 could extract the
desired information from database. There is one hooker in
the entire process. The "select" function is the command
which does the formatting and requires a good deal of
experimentation to discover its secrets. But once mastered,
everything will fall into place. All the necessary functions are
available to completely manage the database, such as
adding, deleting, updating, searching and clearing fields and
records. Also there is a calculate command which allows
adding, subtracting, multiplying and dividing any of the
data fields. Also included is a set of utilities which provide all
38 the RAINBOW March, 1983
the required support functions.
I found Homebase easy to use once I got into it and was
pleased with the results. Though it is not a full blown data
base manager, it most certainly has its applications and is
not nearly as costly as its big brothers. I have one suggestion.
1 found the field descriptors to be too limited and narrow.
The addition of a variable length character field would be a
definite asset. That, coupled with the three decimal fields,
would make Homebase a much more versatile package.
1 consider Homebase to be a program of good quality and
design. It is apparent from the documentation and the flow
of the programs themselves that a considerable amount of
thought went into their design. The menus are very well
designed and are laid out in a most appealing manner. As a
database program 1 like Homebase. 1 think its applications
are limited only by its user. It can be tailored to fit your
requirements within the previously mentioned constraints.
For example, it can be used to handle small mailing lists,
club rosters, phone lists or your checking account. The point
is the program is very versatile and has many good
applications. Another strong point is its ability to increase
the size of its output file to the maximum, or update existing
records without the familiar disk thrashing caused by the
expansion of sequential files. The text processing section
will indeed provide the user with the ability to produce good
documents. However, 1 found it a little hard to use, but then
maybe I'm spoiled by word processors. If you want a text
processor capable of generating files for a macro assembler
or a basic compiler, Homebase will do it for you with ease. If
you are looking for a data manager first, then Homebase
may well be the answer and the text processor becomes an
added feature. If you are looking for just a text/word
processor only, then 1 would not recommend Homebase.
Included with the documentation is a phone number you
can call if you have trouble with Homebase to receive
assistance.

By Dan Mickle
Dan Mickle, who wrote this month 's cover article,
and Steve Lipps, who wrote a number of the routines
used in the listings which follow, were both active in
Civil Defense during the 1960s when fallout shelters
seemed to have their heyday. Dan is a self-professed
survivalist, while Steve describes himself as a "hacker
and science fiction buff who reads a lot of post- World
War III fiction. " The two, who operate Circle City
Software, of Indianapolis, have written such software
as Master Disk System, reviewed in last month's
Rainbow.
The history of man contains one war after another. Thus,
I find no reason to believe another war is unthinkable, but
rather, given the nature of humans, 1 personally think it is
inevitable. One can conclude from information coming
from the Soviet Union that they find even the prospect of a
nuclear war not only thinkable but winnable! They have
estimated that were they to strike first against us, they would
probably kill 90-95% of our population. In my opinion they
must feel that our retaliatory counterstrike would only
affect a small percentage of their people and perhaps 10
percent of their technology. They have several reasons for
such an estimate, but a prime reason is that the Russian
people have regular training and monthly scheduled
practice sessions of exactly what they will do if an attack
comes. Workers who labor at a certain factory would
proceed directly to that factory (unless they were already at
work) and begin sand-bagging their machine. They are
responsible for the safety of that machine. Factories are
built decentralized, with separate buildings far enough apart
that if one building takes a direct hit, other buildings might
suffer minimal damage.
Many Americans take a fatalistic outlook at the next big
war. "When it comes, we'll all be killed anyway!" can be
heard from many people. Yet, while the initial explosions
would kill a lot of people, the radiation which follows would
result in many times as many deaths. If our people knew how
to protect themselves against the invisible killer, perhaps not
as many would die.
My analogy to the fatalistic approach is walking down the
middle of a highway, and stating that you don't need to
watch out for traffic, because when a large truck hits you,
you will be dead anyway ... ridiculous! Obviously a truck
need not hit you if you know enough to get to the side of the
road and to watch out for trucks and jump out of the way in
time.
Fallout radiation need not kill you if you know to "jump
out of the way" (seek shelter) in lime. The Fallout program
and this article do not constitute a complete training course
on how to live through war, but 1 hope this information will
help a few more survive, should war come. The information
is as factual as 1 can make it, and is based on material from
the U.S. Government Printing Office at Washington, D.C.
should you wish further information. The first listing is the
heart of the fallout prediction program, and will run on any
16K. extended or disk-extended system. If you have a
printer, the program gives you the option of using that
printer for your output device. NOTE: Since this is a "high
priority" program, the printer utilities patch themselves in
and overwrite any other routines you may have residing in
high memory. The second part of the program may be
MERGEd in, if you have 32K of memory. It is not an
essential part of the program, ltisonlya high-res drawing of
the "cigar shape" of a fallout pattern as a reminder. For
those who do not have the time to punch in the program
from this listing, the Fallout program is available through
Rainbow On Tape.
If our country were attacked, the enemy would be trying
to destroy the United States as a world power. This means
that their primary targets would be our military bases, and
our nation's capitol. However, many military bases exist
near large cities, so those would suffer the same as the
primary targets. The larger cities are targeted anyway, due
to factories and plants which can be easily converted to
wartime equipment production, or natural port areas for
staging counterstrikes. Claiming the inaccuracy of enemy
targeting computers and rocket control interfaces, it is
estimated by some that their bombs may strike many miles
from the intended target, through over/undershot.
Important targets will get more than one bomb, but even
then the unknown element of warhead "fratricide"(a theory
stating that the first explosion might destroy the electronics
of others in the same area) may spare millions.
YOU ARE ALIVE. The wave of missiles has gone off,
and you survived the searing heat of the fireball. What's
next? Shock-wave! The shock travels at the speed of sound
outward from the blast, just as thunder follows lightning. It
will hit like an extremely powerful earthquake causing
buildings within several miles of the blast to be leveled, and
lesser damage like shattered windows twenty or more miles
out. The initial blast also spreads radiation outward a
distance equal to the crosswind value. You will see that if
you have a wind speed of zero, the upwind and crosswind
values are the same and the fallout would eventually settle in
40 the RAINBOW March, 1983
a circle no greater than the maximum width value. In reality,
terrain and other features in your area will affect how large a
dose you can expect. A hill sitting between you and the blast
will act as a natural barrier which could save your life.
For the sake of an example, let us imagine that a nuclear
bomb has just gone off 25 miles away to the north. You were
asleep in your bedroom. Your curtains could have just
caught fire, but you were not directly in line with the heat
from the fireball. You have a choice which depends a lot
upon your exact situation at the time. Pull the blankets and
covers completely over you head, then you may: 1 ) stay
where you are, 2) crawl to a closet, closing the door, 3) crawl
under the bed (not likely for most adults), 4) keeping the
covers over you, push up the rnattress and crawl under it
(not likely for children), 5) if a cellar door is near your bed,
crawl there. Roughly calculating the Shockwave at five
seconds per mile, you figure you have two minutes before
the Shockwave hits, and things fall in on you. This is the
main reason to crawl quickly to the closest place of relative
safety. The bathtub, perhaps? If you were outside in the
open, a culvert or even a ditch or shallow depression might
protect you f rom the blast. The fireball would probably still
be going on when the shocks hit. A ground shock would
come first, followed by the air-shock, because a Shockwave
travels faster through solid objects (the Earth).
Since there would be no electricity to power your Color
Computer, you should commit the tables to memory, or at
least to paper. You know that the normal wind in your area
blows east, going back to the example, and that you are
south of the blast. You will be able to guesstimate a 10
megaton blast basqd on the severity of the blast at this
distance (severe, but you made it) and you will know that
you are probably now getting in the neighborhood of 50
roentgens per hour. A dosage of 450 roentgens will kill 50
percent of the people exposed to that much. Since radiation
is cumulative, you will reach that level in nine hours of
exposure, and it will be a slow painful death. However,
according to goverment figures, every three inches of earth
you can put between you and the radiation will cut the level
in half. Let us say your house is still relatively intact. If you
are going to rush going outside to shovel dirt over cellar
windows, or up around the foundation, do it now. Grab a
rubber raincoat or other easily brushed-off article of
clothing. If you don't have a hood, you might tie a plastic
trashbag over your head to keep the dust from settling
directly on you. Tie a scarf of towel over your mouth.
SPEED IS ESSENTIAL. You may not be able to draw any
water if the pipes were damaged, so you can't wet the rag,
but you may have stocked the cellar with a few plastic jugs of
drinking water. Stay outside for as short a time as possible,
but try to seal up any major cracks which will let the dust in
directly. Inside the house, drag mattresses and furniture
over the spot you will be staying or around a closet, etc. Get
into your shelter, breathe through clean towels or clothing,
and stay there as long as possible. Remember that the wind
could have shifted, putting you into the heart of the hot
(3000+ roentgen) zone in which 10 to 12 minutes of exposure
can be enough to kill you. Since the fallout is carried by the
air (wind) after the initial blast, the radiation level which
started at about 50 in this example, could be 100 within a
half hour, 300 within an hour, 1000 within an hour and a
half, and 3000 in two hours.
You can see that what you do in the first few minutes
might save your life. Even if you are directly in the path of
the hottest radiation zone, it could take a couple hours or
more to build up to that level. The radiation level drops off
rapidly with time. The 3000 roentgen level will only last
seven to eight hours after the blast for a 10 megaton size or
24 hours for a 50 megaton bomb. For a 1 0 megaton blast the
radiation will have dropped below 100 again in about 36
hours, but for the largest bombs this will take five days. If
you were that close to a 50 megaton blast (25 miles) you
would likely be dead from burns, or at least blinded. A 50
megaton blast can cause flash burns and blindness to 50
miles away. Several smaller bombs saturating an area could
give the same effect.
You should try to stay in your shelter for two weeks at
least but three would be better. If you must come out for any
reason, wait as long as you can before going out, bundle up
as though going into a blizzard, stay out not one second
longer than you have to. Remove the outside clothes and
leave them near the door (as far as you can away from you).
Don't forget boots and covering your mouth.
Those victims of the initial blast still living may have
broken bones, burns, or blindness. Splint broken bones
using a stick, leg of a chair, etc., and tape or rags, getting
them as straight as possible. Burns should be rinsed if water
is available, then treat as any normal burn, giving aspirins or
any other available medicines to cut the pain. If a victim has
been blinded, especially if there are no serious burnsaround
the eyes, keep the eyes covered for several days, checking
occasionally whether sight has returned. Such blindness
could be temporary if the person is given time to recuperate.
Victims of radiation will experience varying degrees of
nausea, vomiting, diarrhea, cramps, and even coughing up
blood. Radiation first attacks the body's immune system, so
germs that already exist in your body can make you very

The first listing which follows is the heart of the fallout
prediction program, and will run on any I6K ECB or disk-
extended system. If you have a printer the program gives
you the option of using that printer for your output device.
NOTE: Since this is a high-priority program the printer
utilities patch themselves in and overwrite any other
routines you may have residing in high memory. The second
listing is not an essential part of the program. It is only a
high-res drawing of the "cigar-shape" of a fallout pattern as
a reminder. For those who do not have the time to punch in
the program from this listing, I understand the Fallout
program will be available through Rainbow On Tape.

Software Review...
HBA is
Home Buyer's Helper
There are very few experiences in life that can match the
complexity of buying your own home. The most difficult
aspect of deciding whether or not to buy your dream house
is, can I afford it. This decision is not easy since there are
many factors involved. You have to consider the cost of the
house, the prevailing interest rate, property taxes, and
closing costs to name a few. After you have gathered all the
information you need, you sit down with your trusty
calculator and peck away for an hour or so. But what if you
decide to make a larger down payment, and/ or the interest
rate changes? This "what if" situation was just meant for
your favorite computer. You cannot only put it to work, but
you can answer the "but what can it do besides play games?"
question that I'm sure you have all heard at one time or
another. If you are still with me, this is where the purpose of
this review comes in.
The Home Buyer's Analyzer, which I shall refer to as
HBA from now on, is a set of programs that will enable you
to easily figure out exactly what it will cost you to buy a
home. But this is only the beginning. Its many features
include calculations of monthly payment, effective monthly
payment after tax considerations, effects of appreciation in
the value of the home, federal tax benefits, year of sale
figures, and many more. HBA can handle a loan of up to
forty years, and can calculate net proceeds from sale forany
given year during the term of the mortgage. The various
federal tax tables are also included to allow for your filing
status. Output from HBA can be directed to yourscreenas
well as printer, and there is also a graph of payments that can
be produced. As if this wasn't enough, you can also save
your input data for future calculations, and the package
comes with sample data so you can quickly learn to use HBA
properly.
Before I describe how HBA operates, I want to make a
very important point regarding its use. There is an acronym
in data processing known as GIGO. It stands for "garbage
in — garbage out." You must do your homework before
relying on the output from HBA. If you feed it with garbage
or incorrect figures, it will give you garbage results in return.
If you have a printer, 1 recommend that you use it so that
you can double check your input.
HBA starts out with a cute picture of a house at night with
smoke coming out of the chimney. If you wait long enough,
it turns to daytime and the grass starts to grow. After a
welcome screen, a reminder to read the documentation, and
some last minute instructions, you are asked if you have a
printer. At this point HBA gets down to business. You are
then asked about your federal income tax filing status,
intended year of purchase, and your state and/ or local tax
bite. You are then presented with a review screen with the
opportunity to make changes in caseyou goofed up. HBA is
now getting ready to ask you a whole slew of questions. It is
here that your previously saved figures can be recalled if you
want. Some of the things you are asked at this point are
purchase price, down payment, interest rate, term of
mortgage, and annual income. As before you are given a
review screen before proceeding. By the way HBA also
handles balloon (variable rate) mortgages.
So far HBA has been a one-way street. Nothing but
questions, questions, questions. How about some output?
Here is where HBA really shines, but first some more
quesions. What kind of output do you want? You can get a
particular year displayed, all years plus year of sale, or year
of sale only. Some of the output figures are monthly
payment (with and without property taxes included),
mortgage balance, interest paid, and your federal income
tax with and without your tax benefits from interest and
property tax deductions. After reviewing your output you
are asked (what, more questions!) if you would like a graph
produced showing your total payment, effective (after tax)
payment, and effective payment after property
appreciation. This was the only feature of HBA I thought
could use some improvement. The three lines plotted on the
graph were usually too close together due to the scale
chosen. Asfaras I'm concerned this is a very minor problem,
and in fact the graph feature is really just a frill and in no way
affects the real value of HBA. Last but not least, your final
two questions. Do you want to save your input figures and
do you want another go at it.
Computers are very good at number crunching and HBA
will push your CoCo to its limits. The documentation
included is complete and will hold your hand all the way
through. Most importantly, there are definitions given for
all of the input and output fields. No assumption is made
that you understand all the buzz words involved in such a
complex scenario. If you are in the market for a home,
consider HBA before you buy.

DOS Detach'
Saves Wear and Tear
By Herbert Schroeder
The attached listing should be of interest to Color
Computer owners with disk drives. The program allows you
to "detach" the disk operating system (i.e. return control to
non-disk Extended BASIC) without having to physically
unplug the disk controller. The advantage of this is that now
you can run machine language programs that won't work on
the Radio Shack disk system without the hassle of
unplugging the disk ROM Pack. This saves wear and tear on
the connectors, reducing the chances of I/O errors due to
bad connections.
The program can be loaded from tape or disk. After
running, it will tell you to press reset. When you do this, the
computer does a cold start from Extended BASIC, ignoring
the function exactly as if the disk drive were unplugged, even
though the controller is in fact still in the ROM port. You
can even use the high-speed poke. I can't guarantee that this
procedure is fool-proof, but so far it has enabled me to run
every "non-disk" program (machine language and BASIC)
that I own without unplugging the drive.
To reattach the disk operating system, type POKE 1 13,0
and press Reset. This does a cold start to disk Basic.

The program works by copying the RAM initialization
routines put of BASIC and Extended BASIC and into high
RAM. It alters the routines to omit the check for the
presence of the disk controller. (Note: the disk controller
does not use pins 7 and 8 to auto start the way other ROM
packs do.) The Reset vector is changed to point to the
altered intialization code. The part of the initialization
routine that checks for memory size must also be altered, or
else it interferes with the code in RAM. This is done in lines
51 to 53, by directly inserting the memory size for your
machine. As printed here it is for a 32K computer. For 16K
change the "&H7F" in line 52 to "&H3F." For a 16K
machine, you will also need to change the location in RAM
where the code is copied. (I put mine starting at &H7000.)
I hope this procedure will save other disk owners as much
annoyance and frustration as it has me.

Power
(of Attorney)
At Your
Fingertips
By Glenn B. Knight
1 am happiest when 1 can send a check to some young
computer wizard and get a program that will do something 1
want my computer to do for me. Eventually the world will
awaken and recognize what we color computer pioneers
have been telling them (that we are an insatiable market),
and we will have all of the software that we need. That day is
not yet today — so every now and then we have to write a
program to meet our particular needs.
This little gem was zapped out (if you can call two weeks'
work zapping out) when I was forced tofork over thirty-five
hard-earned bucks to a lawyer for a Power of Attorney. I am
by no means a programmer, and the results show it — but the
bottom line is that it does the job.
Our son was going to visit relatives for two weeks, and we
wanted to give them permission to have a doctor glue him
back together, if he were to fall off his dirt bike.
This POA looked almost exactly like the one we got last
year for our daughter to visit my sister, and an awful lot like
the one we had for a friend to sell our car during one of our
frequent moves. They could have been'mass produced by a
computer. (This is when the light bulb appeared over my
head.)
On closer examination 1 saw the POA as a series of sub-
routines with variable strings of information inserted. The
only difference between a POA to sell a car or one to
authorize medical care was a single paragraph.
Since 1 had just picked up a Line Printer Vll on sale and
was anxious to see what it could doforme, I decided to have
it print a Power of Attorney.
As things turned out, 1 got carried away and wrote
instructions that offer five different Powers of Attorney:
1 - to sell an auto
2 - to register an auto
3 - to get medical care for a child
4 - to rent a house to someone
5 - to sell a house
In addition to that, it will print the Notary statement at
the bottom, if you want it, and it will even include the name
of the Notary, if you have it. Then it will giveyou the option
to print a duplicate copy, again, only if you want it. This
program is so user friendly that it even thanks you for
allowing it to serve you.
One word of caution — these are simple Powers of
Attorney; if your situation is complicated, or you are doing
this as part of your business, consult a lawyer. Unless you
have a simple situation, and the POA fits your needs
EXACTLY, get professional help. But for90 per cent ofthe
times you will need a personal POA, this program will do
just fine.
You will still have to get your POA notarized.
Hmmmmm, 1 wonder how you go about having a Color
Computer commissioned a Notary?

With the rising cost of utility bills, it gets harder and
harder to budget the family income. Here's a program that
will help you keep track of your utility cost and usage.
All you do is enter the information from your utility bills
and the program arranges it, computes totals, and prints it
to the screen or printer as you request. It makes it easier to
spot errors in billing as well as allow you to see the average
monthly cost of your utilities.
While this program is written for the Albuquerque, NM.
area, it can be applied to your area. too. with little or no
modification.
It is not necessary to fill in all the data requested. Just fill
in the information that is listed on your bill. The program
uses REMark statements to show where specific sections
are. Using these REMarks. you can find and change any
headings necessary. It shouldn't be necessary to change any
variables.
A Sample Printout
Now. let's look at the sample data printout. You can see
that the first section of the printout deals with the electric bill
summary. The next sections are for the gas bill and the water
bill summaries. These list the data for the months you have
entered. In these examples, 1 have used the actual data from
my 19X1 utility bill records. When you run this program, the
computer will prompt you for the inputs in the same order as
they are listed in the sample printout headers.
The final section is the summary lor all utility costs. It
prints out an amount f oreach utility for all 1 2 months, even
if you have not made any entries for those months. The
screen printout will be similar to the hardcopy, except that it
will be in an abbreviated format and will list cost, usage and
totals on three separate pages. This is because of the small
screen si?e.

If your printer has a form-t eed function, you can change
C4$ to the code for FORM FEED (CH R$( I 2)). Change C6$
to reflect the column width of your printer. You should use
at least an 80 column printer if you do not wish to make
major program modifications. Also, change C2$ and C3$ to
the values required 1 or your printer.
You mu.si enter the bills in chronological order; enter the
January electric bill before entering the February electric
bill. You can enter all of the electric bills before entering
either gas or water bills or yice versa. If you enter the months
out of order, the data on the summary sheets will also be out
of order. The program matches the name ol the month to the
months listed in the data statements in the program to
determine if the month wasentered properly. If not, you will
get a tone and a flashing warning and you will have to re-
enter the month.
When you enter the actual cost of the utilities, do not use
dollar signs ($). The program will automatically enter them
for you.

The program has no editor, but you can edit data by
breaking the program and changing the incorrect variable.
For example, assume that the electric charge for the March
entry was incorrect. It shows that the electric charge was
$39.29. Now, if you wanted to change it to £38.29, you
would start by pressing BREAK. Look at the program
listing. Entries for the electric bill start at line 1430. When
you ran the program, you saw that the month of the bill is
entered first followed by the base electric charge. Startingat
line 1430, the first INPUT statement is E1$(E9) for the
month. The second INPUT statement is E2(E9) for the
electric charge. Since March is the third month, E9 will
equal three. After you press BREAK, type the following to
change the data
E2(3)=38.29:CONT
This will change the electric charge from $39.29 to $38.29
and restart the program. Press ENTER again to call the
error routine, then answer the prompts. This type of data
editing will work for all programs written in Basic as long as
you don't have a syntax error. If you attempt to RUN the
program instead of CONTinuing it, or, if you have a syntax
error, the program pointers will be reset and the data will be
lost.
A Final Word
Program Requirements
The program will run with I6K of RAM if the REMarks
are deleted. It requires Extended Basic only because of the
PRINTUSING statements. If you change these statements,
you can run without Extended Basic.
The program was written to be used with a Line Printer
VII. 1 have used printer control codes for those who wish to
use this program with another type of printer. The codes are
set in lines 1 130 and I 140. Look at the following table for a
list of the code functions:
Printer Code Functions
C1$=LINE FEED
C2$=NORMAL WIDTH PRINT
C3$=DOUBLE WIDTH PRINT
C4$=FIVE LINE FEEDS
C5$=DOUBLE WIDE HEADER
C6$=80 COLUMN LINE
C7$=FOR SCREEN PRINT
The program is simple to use once you become familiar
with it so give it a try after you have loaded it and saved a
copy to tape. Try all combinations of inputs and check for
error handling to insure that you have loaded it correctly.

When you are ready to use it for keeping your records, you
will see how easy it will be to budget the utility bills. You will
also have a program that your friends and neighbors might
find useful. They will see that you can use your computer for
much more than just playing games.

Computer Shack has been in the publishing business for 2 years publishing software for the TRS-80 Model I and III. We are now
expanding into the COCO. If you would like a major publisher to handle your software send us a copy for evaluation. We have full color
packaging, and established dealer network, foreign distributors, and have booths at major computer shows throughoutthe country, etc.
We can sell more copies of your programs than any other distributor. If you are a machine language programmer we have some
programs that run on the model I and III that wewould like to convert to the COCO. If you are interested in this send us a sample of your
programming along with your name and address.
Our new 32 page catalog (Model 1,111 and COCO) is hot off the press. It contains software, hardware, and misc. If you live in the U.S. write
now for your free copy. Due to the high cost of mailing, if you live outside the U.S. please send $1 .00 for your catalog and we will refund
this on your first order.
Note our policy of giving a discountf or larger orders. We make more money on a big order and we pass the savings along to you. You can
save 20% on all your software by buying 4 programs.
PRINTERS & PRINT BUFFERS
The COCO has a serial print port and to use a printeryou must either buy
a serial printer (they cost more) or buy a converter. Computer Shack now
has a converter that also stores the data in its memory untol the printer
is ready tor it. This is an outstanding feature as most printers are fairly
slow.

PRICKLY- PEAR SOFTWARE
QUALITY PROGRAMS FOR YOUR COCO & TDP-100
PROGRAMS REQUIRE 16K EXTENDED BASIC FOR TAPE, AND 32K DISK UNLESS OTHERWISE NOTED.
Flight
If you'd like to fly a plane then this is what you've been
waiting for. A really good graphics oriented flight simulator
in high resolution. Four difficulty levels let you go from
student level to a difficult instrument-only landing. In front
of you on the screen are your instruments, and above
them are two representations of your plane in relation to
the flight path (top and side views). At the higher levels all
you have to go by are the instruments. Can you put it down
on the runway to hear the synthesized voice from the
tower say "perfect landing"? It's tough! You use your
joystick just like the control stick on a plane, and the action
is realistic indeed. This program was written by a pro-
fessional flyer— a pilot for a major United States air carrier,
and the high standards of professionalism really show.
Just CLOADM and take to the skies!! Requires 32K
extended. TAPE is $19.95 — DISK is $24.95
Las Vegas Weekend
Two great high-resolution games. You will really feel
you've had a vacation. First, play a round of golf. It all
happens in high resolution. Choose yourclub, decide how
to swing, and go for it, but watch out for the sand traps and
water hazzards! This course would challenge the pros.
When you get on the green, the scene zooms in for a
closeup view while you putt.
After your shower, go down to the casino and play some
poker against the computer. High-resolution graphics
plays just like the draw poker machines in Vegas. Win big . .
maybe. Both great games are included i n the Las Vegas
Weekend, on separate tapes or one disk. $24.95 tape —
$29.95 disk
The Fantasy Master's Secretary
This program will be greatly appreciated by the many
people trying to run a fantasy game! It's not easy to keep
track of hit points, charges in magic items, monsters, game
time, armor values, and a lot more, all while trying to
conduct a meelee and listen to 8 people talking at once. If
you ever thought you needed a secretary, this is it! It keeps
track of all the above and more, and even has a help file in
case you forget how to use it. It also figures the experience
points of monsters while keeping an electronic eye on
value and weight of treasure found. You'll truly wonder
how you got along without it!!! If you quit before the
campaign is completed, you can save the whole thing to
tape (or disk) and take up right where you left off next time
you play. At the beginning it will ask you whether or not the
players can see the screen, and set itsdisplays up accord-
ingly. Remember, this isn't a game — it's an aid to use with
a fantasy game. $19.95 tape — $24.95 disk.
Eight-bit Bartender:
This will light up your next party! Over 100 great drink
recipes are stored by the bartender and called up at your
command. Askf or them by drink name, main liquor used, or
class of drink (highball, cocktail, etc.). These were gathered
from the favorites and house specialties at famous pubs
and taverns across the US. It outputs to the screen, printer,
or both! At your next party let the guests browse through
the Bartender. Needs 32K. TAPE $1 9.95 — DISK$24.95
Phonics I
This classroom-tested program is the newest in our Phonics
series. Written by the same elementary school teacher, it
takes up where PREREAD I, II, & III leave off. Actually two
programs (on separate tapes), the TUTORIAL teaches all
22 of the consonant blends using on-screen graphics and
voice(controlledbythe computer and played through the
TV speaker). The TEST program asks for the letters in
these blends(again using voice through t the speaker), and
checks the keyboard input for the correct answer. Again,
on screen graphics are used as an aid to learning, and
immediate feedback to the learner is given.
Phonics II
Similar toPhonics I in concept and execution, but Phonics
II teaches consonant digraphs. Again there are two pro-
grams (on different tapes) for the TUTORIAL and TEST
modes.
Both Phonics I and Phonics II are well documented, and are
sold separately on TAPES for $24.95 each. They are also
available as a package — only on DISK for $44.95.

Starship Hercules: Well
Documented, Sophisticated
Fun
Although I am not an avid game player, my son Philip
(age 10) and I enjoyed this space game, Starship Hercules —
a refreshing change from the Pac-Man and Space Assault
type of games which are so popular. The lower skill levels
allowed us to learn the basics of the game; the more
advanced levels offered us a real challenge and a chance to
develop playing strategies. While learning, we needed to
refer frequently to the detailed instruction booklet (27
pages). It always provided the desired information. The
following paragraphs describe the game and its
documentation.
The game is written in BASIC and requires 2 I K of RAM
(hence a 32K Color Computer). Most of the game is played
viewing a screen that shows both an area map (quadrant —
explained below) around the Starship Hercules and
important data. The quadrant map displays the Hercules
and any stars, starbases, or Zargons in that quadrant. The
symbols are not generated using any of the graphics
modes - they are produced using the various ASCII codes
above &H7F.
As captain of the Starship Hercules, I am commissioned
to seek out and destroy the invading Zargon spaceships. I
have limited amounts of energy, weapons, and time to do
this. These enemy ships are hiding in an 8 quadrant by 8
quadrant matrix (the Buffer Zone), which I can search, one
quadrant at a time.
To aid me, 1 have the Hercules' shipboard computer,
which performs several functions:
1. It gives me navigation data to the Starbases (space
stations) where I can get refueled and additional weapons.
Any damaged Hercules systems can also be repaired at these
Starbases.
2. It shows me what I have found in already-explored
quadrants, and which quadrants 1 have yet to explore.
3. It calculates navigational data (speed and direction)
from my present location to any other quadrant.
4. It gives me a status report — energy and time remaining,
Zargons remaining, and the status of all Hercules systems.
Once I find one (or more) Zargons, the Hercules
computer' calculates the firing angles for my photon
torpedoes (if neither the computer nor my weapons systems
have been damaged in a recent battle).
Each time I play the game, I am offered a choice of
difficulty levels. At the more difficult levels, the Zargons
move from quadrant to quadrant, they have more energy
(which means they're harder to destroy), and they use a
special weapon to reduce my defenses. In addition, the
Hercules systems (navigation, computer, weapons, and
defense) break down more frequently and take longer to
repair. While these systems are damaged, I must rely on my
own memory and resourcefulness to outwit the Zargons.
The number of Zargon ships (and their locations, of
course) vary in each game, as does the number and location
of the Starbases for refueling, rearming, and repairing the
Hercules. And the Stardates (time allowed to destroy the
Zargon fleet) differ in each game.
Particularly important for a game as complicated as
Starship Hercules are the instructions. In this case, the 27-
page booklet details every aspect of the game. Philip (my 1 0
year old son) lacked the patience to read them — this game is
apparently intended for older (and more patient) readers of
teen age or older. The only deficiency I noted was the rather
poor quality of the illustrations (made with a printer, using
symbols different from those in the game) and their
placement all together at the end of the booklet; it would
have been less confusing to place each diagram near the text
it illustrated.
In summary, Philip and I bothenjoyedthisgame. The few
points about which 1 was still confused after reading the
complete instructions were quickly cleared up when we
began to play. I definitely consider Starship Hercules worth
the retail price.

Galactic Hangman
Can Get You Hooked
Looking for a fun game? One that takes some thinking, is
educational, and the whole family can enjoy? Sugar
Software has come up with a fun, space-age version of the
popular game of Hangman. The program Galactic
Hangman comes with both a 1 6 K and 32K version on the
same tape. Both versions have Sugar's auto-load feature
built in, which makes the tape easy to load quickly. The idea
of a 16 K and 32 K version on the same tape is ideal for those
of you who have 1 6K now but plan to upgrade sometime in
the future.

First, let's talk about the 16K version. After loading, the
computer instructs you to choose one of 14 different files of
50 words each that are part of the program. You are then
instructed to choose between a word from the computer's
memory and one of your own. All the letters of thealphabet
appear at the top of the screen and change color as they are
chosen. 1 won't discuss the graphics except to say that they
are good, fun, and entertaining. Provision is made in the
16K version for creating and storing as many 50 word files as
you wish to recall later on.
Except for the file recall feature, the 32K version has all
the features of the I6K version, plus many others. The
graphics are more "galactic" and the computer chooses
randomly from 700 everyday words that are stored in the
memory. The words appear to be well chosen and of average
difficulty. This is the problem with many hangman-type
games — the words are either too simple or too uncommon.
Also, with the 32K version, if you load the tape and take no
more action, the computer automatically begins choosing
words and playing against itself giving a complete
demonstration of how the game is played.
One feature which could be added to make thegame more
exciting would be the addition of a time clock. An additional
letter would have to be chosen, say within 20 seconds or you
have to move up one more step to the hangman's noose.
The documentation is good, both in the instruction
booklet and on the tape. Galactic Hangman is
recommended for, among others, those looking for a game
that you can play with your grandparents and convince
them that buying you that expensive CoCo was a wise thing
to do.

Software Review...
Match-It Works Well
With Young Learners
By Brian James
Match-It is an educational program from Micro School
Programs (Bertamax Inc.) to help children learn to
recognize which upper and lower case alphabet letters
belong to each other. Suggested for youngsters from age
four to six, Match-It comes in both cassette and disk media
for the 32K computer. Although thedisk version was used
for this review, it appears the cassette version is exactly the
same.
I n Match-It, a letter appears on the lef t side of the screen
while letters of the opposite case appear, one at a time, on
the right side of the screen. When the correct letter match
finally appears on the right, the user presses the space barto
indicate a match. The computer will indicate a correct
answer with a happy face and an incorrect match with a sad
face. Sound is also used in conjunction with the happy/ sad
faces. After all 26 letters have been given and matched, a
record of how many tries it took to match each lettershould
appear on the screen along with a "goodbye" to the user. I
say "should" because in reality the screen only indicates with
a which letters had one or more misses. This was the
only major discrepancy I could find in an otherwise
excellent documentation booklet that comes with the
program.
Before the program begins in earnest, the user (or parent
or teacher) is prompted to decide on a number of options.
These include whether upper or lower case letters will
appear on the left side of the screen, in what orderthe letters
are to appear (alphabetical or random) and at what speed
are the letters on the right side to alternate. The user may
also try an example problem before beginning the 26 letter
sequence. The documentation suggests that an adult should
explain the object of the program to the user, and help select
order, level and speed of the program. This is a very wise
suggestion considering the age level of the children using the
program.
How well does it work? 1 tested it with my seven year old
daughter and although she is one year older than the
suggested age level, she liked the program very much. The
greatest appeal seemed to be the nicely done graphics and
the immediate feedback the program gives you through
sound and color. She had a little problem reading some of
the characters (made with lower resolution blocks) and a big
problem trying to do the program at the highest speed. I
found the highest speed hard also. The space bar didn't quite
respond as fast as the program wanted it to.
In summary, Match-It is a good teaching program to help
children learn to recognize upper and lower case letters.
Even though the program is written in BASIC, it uses a very
nice upper and lower case character set to print instructions
and prompts. The age levels suggested (four through six) are
perfect for the activity presented. I have heard that Micro
School Programs is converting most of their educational
programs for use on the 80C. This program illustrates the
appealing quality color graphics and sound have in the
educational area and how well suited the Color Computer is
as a learning tool for children. Parents and educators would
do well to write the company for a list of their 80C programs.

A WORD FROM THE SPONSOR
Hi again. This is Month Three in my series of short chats
about various Color computer subjects in these Star-Kits
ads. Hope you are finding them interesting and useful.
Quite often, after running a machine language program, I
find that my CoCo doesn't want to accept Basic programs.
The common solution, of course, is to turn the power off
and then back on. This does a complete reset of the
computer and fixes some of the pointers which the machine
language program clobbers.
But here's a better way that doesn't put your computer
through the power on/off stress: simply type POKE 113,3
and push the RESET button on the back. The POKE makes
Basic forget that it has already been reset before, so pushing
the RESET forces it to go through the same complete reset
as if power had first been applied.
In fact, I have one Basic program which does several
CLEARs and PCLEARs that leave the computer in a state
where it won't run other programs unless everything is
reset. To avoid the need to manually reset the system after
this program is finished, I added one last line which reads
POKE 113,3 : EXEC 40999. The EXEC restarts Basic
exactly the same as if 1 had pressed RESET (except for one
difference — in a 64K system you must physically press
RESET to return from 64K mode back to 32K mode after
running a 64K program.)
Are you using a non — Radio Shack tape recorder with
your CoCo? If so, then it's quite possible that the motor
control relay in your CoCo is not able to handle the recorder
motor current. When that happens, the computer can't turn
off the motor because the relay contacts have welded
together. The new CoCo models have a better motor
control relay to fix the problem, but what about the rest of
us?
If the relay doesn't get to the point where the contacts are
permanently stuck together, then it's possible to solve the
problem by adding a simple circuit between the computer
and the recorder. It uses just a few parts readily available at
your local Radio Shack — send us a self-addressed stamped
envelope for a free diagram and instructions. (Hope you
don't mind if we enclose a Star Kits catalog too, while we're
at it.)
If you're into engineering or math, you might be
interested in our new educational package. Introduction to
Numerical Methods is a college sophomore level course
which combines a 324-page text with a number of Basic
programs which go along with the text and illustrate each
topic. Some knowledge of calculus is required, and the
package covers a variety of topics in numerical analysis.
This is probably the most painless way to learn a very useful
topic; at $75 it's quite a bit cheaper than going to college.
Finally ... if you have purchased a Star-Kits program,
please make sure to return the user registration form from
your manual along with an envelope. VVe periodically send
out our Users' Group Newsletter with other hints and kinks,
and these forms and envelopes are our only way of keeping
you up to date.

Screen Control
By R. N. Roberts
Unfortunately, I'm seldom able to express myself in tidy
little sentences of 32 characters or less, and frequently my
print lines do runneth over to the next line on the TV screen.
Nothing wrong with that, but when a word gets split in the
process, I see Color Code 4 (to you beginners and
unfortunates with other machines that's red). 1 hateto think
of the time I've spent counting characters and inserting
blanks in print statements in order to push a split word back
to the start of the next line. If you feel the same, the
following subroutine (named Screen Control) will provide
relief.
Another equally useful feature of Screen Control is its
abil'ty to automatically stop printing when the screen is full.
This feature lets you view text printed by a program one
screen at a time. No longer do you have to sit with your
fingers on the "shift" and "@" keys, poised like a cobra to
strike in that one split second when the new lines reach the
top of the screen. (It is unfortunate that there is not a similar
routine in ROM for use when listing a Basic program.)
Screen Control eliminates the need to count how many lines
will fill a creen and then insert the familiar:
PRINT "HIT ENTER TO CONTINUE"; INPUT
A$:CLS
Using Screen Control
To use Screen Control, first CLEA R 500 bytes of string
storage space. The extra memory is the price paid for the
subroutine. Next set the string you want to print equal to Z$
and execute a GOSUBlo the subroutine. (I reserve the use of
the letter Z for variables used in utility programs to avoid
'Wo longer do you have to sit
with your fingers on the 'shift'
and '@ ' keys, poised like a cobra
to strike in that one split
second... "
inadvertently using a variable in a program and a utility at
the same time.) That's all there is to it.
A semicolon placed at the end of a PRINT string will
cause the following material to start printing at the end of
the first string. The same effect is achieved in Screen Control
by directing the GOSUBlo line 1 50. For the same effect as a
PRINT without the semicolon, GOSUB to line 140.
If you enter the subroutine with a string which would
normally cause the screen to scroll, Screen Con/rolw\\\ print
as much of the string as it can, print a prompt on the bottom
line and then beep. Hitting the ENTER key will clear the
screen and the remainder of the string will be printed at the
top of the screen. If you use lowercase letters for the prompt
it will readily attract the eye of the user. If you use this
subroutine in a program which does not haveto bevery user
friendly you might consider changing the prompt to "more"
or even " — )".
Should you desire to disable the screen paging feature,
replace lines 290 and 310 with RETURN statements and
delete line 300. To use the page control part of the program
only, set your strings equal to ZZ$ and execute a GOSUBlo
line 290.
As listed, statements 20 to 130 are not necessary to the
operation of the program. If you RUN the program after
keying it in, lines 20 to 130 illustrate the working of the
subroutine. After you experiment with the program you will
want to delete them.
How It Works
All you folks who only want to copy and compute can go
to work now. From here on out, it's going to be a nuts and
bolts discussion of how the program works. First, the
variables used are defined in Table I.
Table 1
SCREENCL variables
ZW Flag for printing. 0=Print; I=Print
Z$ — Text string to be processed
ZZ$ The part of Z$ to be printed
Zl. Print positions between cursor location and end of
line
ZS - Number of characters in string Z$
ZR — Number of unprinted characters in string.
Next a review of the POS function. POS(0) returns the
position of the cursor on a screen line. The values returned
by POS(0) are "0" for the start of a line and "3 1 " for the end
of a line.
The POS function only tells where the cursor is in a line.
In order to completely establish the location of the cursor on
the screen, it is necessary to get the cursor address from
memory locations 136 and 137. Memory addresses require
two bytes of storage and are converted to a decimal value by
the formula:
256*PEEK(\sl byte)+ PEE K(2nd byte)
or, in this case:
Cursor address=256* PEEK(\16)+PEEK( 137)
The cursor address will be a number between 1024 and
1535. the beginning and end of text screen memory.
If you do not have Extended Color Basic, the POS
function can be duplicated by the following code used as a
subroutine:
1000 PO=256*/'£-£'A:(I36)+/'£'£'K(137)

1020 Return
Upon return from this subroutine the variable PO will
have the same value as would be returned by POS(0).
Statement 10 clears the required string space. Statements
140 to 280 are the string handling part of the program and
statements 290-310 are the page control sections.
String Handling Subsection
Statement 140 sets ZW=I indicating that semicolon type
printing is not desired. ZW is checked in statement 270 after
all the string is printed. Statement 270 will return control to
the calling program if ZW=0, leaving the cursor at the end of
the string. Otherwise, line 280 resets ZW to zero and, if the
cursor is not on the last line, skips to the start of the next line
by executing a PRIN T statement.
Statement 150 adds a blank to the end of a string on the
screen if the cursor is not at the beginning of the line and the
first character of the new string is not a blank.
Statement 160 deletes a leading blank from a string if the
string will be printed at the beginning of a line. If you want to
indent a line, use one more leading blank than you would
when using a regular PRINT command. ZL is set equal to
the number of print positions between the cursor and the
end of the line in statement I 70. Statement 180setsZS equal
to the number of characters in the string to be printed.
Statement 190 prints the string if it will fit between the
cursor and the end of the line. Printing in this statement, as
well as other statements, is done by setting the string to be
printed equal to ZZ$ and executing a GO SUB to statement
290, the page control part of the program. If printing occurs
at statement 190, all the string has been printed and control

goes to statement 270 which, as mentioned above,
determines if semicolon printing is required.
Statements 200 through 240are the heart of the program.
If the character which would be printed at the end of the line
or the next character is a blank, then a word is not split. In
this case, the original string, Z$, is broken in two parts. The
left part is printed in the balance of the line the cursor is on,
ZR is set equal to the number of unprinted characters, and
control goes to statement 2 10 which redefines Z$ as the right
part of the string and starts the process over again by
transferring control to line 150.
If the character which would print at the end of the line
and the next character are not blanks, then a word is split
and control goes to statement 220 which steps backward
through the string starting at the end of line character until it
finds a blank or reaches the start of the string. When a blank
is found, the left portion of the string up to that point is
printed on the line the cursor is on. ZR is then set equal to
the number of unprinted characters and control goes to
statement 210. If a blank is not found, it means that the word
is too big for the space remaining in the line, and control
passes to statement 250 which skips to the next line unless
the cursor is on the last line. Issuing a PRIN T command
when the cursor is on the last line will cause the top line to
scroll off the screen which, of course, is a no-no. If the cursor
is on the last line, control goes to the page control section of
the subroutine to print the prompt.
Page Control Subsection
Statement 290 is the first line of the page control section.
If the present cursor location plus the length of the string to
be printed is greater than I512 then control goes to
statement 310 to print the prompt. 1512 is the text screen
address a few characters before the prompt. Color Basic
users can replace the Z.//V£'//V/ > (//"instruction in statement
310withan//V/ 5 t/rstatement. 1 used UNEINPUTlo avoid
printing the question mark after the prompt. Af ter the user
responds, the screen is cleared, the waiting string is printed
at the top of the screen, and control returns to the main
program.
That's all there is to it. Now you can have neat text
displays with a minimum of programming effort.

Final Countdown
Save The World— Don't Blow It
By Paula Giese
When I first started gaming, 1 didn't do too well. I was
always trying to HUG DWARF, KISS GIANT (I like big
guys), or FEED DRAGON (an endangered species, after
all). And though I like Adventuring, the constant need to
KILL, STAB, SHOOT, H IT, and so on, is wearisome. The
hero-gamer always seems to be a man, often bent on
rescuing some tedious, chunky little princess-type who's tied
up someplace. Off-putting for us tall, fast-moving ladies.
In real life, 1 am a private detective; I do have what I
suppose some would consider "adventures." In real life,
these are boring, scary, cold, slow, heartbreaking. M ost are
best handled with a smile, fundamental respect for people,
and a cool head. I don't carry a gun. I've worked to end war
for a long time, so shoot 'em-ups and galactic war games
hardly thrill me, though unlike the present Administration, I
don't think video games are causing kids to beat up on (or
shoot) their folks any more than usual. Hence, I was
delighted to see a game whose purpose was for the
protagonist to prevent a war, rather than to knock out some
alleged baddies with smart bombs, lasers, and what-not; or
to get anti-social against ethnic minorities (dwarves, ogres)
with more old-fashioned technologies.
Bill and Debbie Cook have written an interesting all-text
Adventure called Final Countdown which starts you outside
a missile base, where a crazed General is about to launch a
nuke, targeting Moscow and starting World War Final, if
you can't abort the thing.
You have to get into the base — there's automatic security
at the gate. Then, find the right tools as you make your way
through secret passages, mazes, adminstrative offices, and a
variety of techno-rooms, to the place where you can abort
the launch. That is, if you don't launch it yourself, by
mistake, or get killed by making mistakes with the hi-tech
gadgetry or by using the wrong tools at the wrong time.
Computers, a two-way radio, and radar screens give you
some scoop, if you interrogate them right. You can ask for
HELP, but you won't get much.
From time to time, the crazed General pops up. If you
don't get him, he'll get you, then that's all, world. Still, true
to your anti-death principles, while you do shoot him (if you
see him in time), it's with a Taser gun, a techno device
developed out of the old electriccattle prod, once beloved of
Southern sheriffs. Although cop catalogs advertise them,
they're not much good. M ost are sold toeasy marks through
ads in masculine righteous-violence fantasy mags like
Soldier of Fortune. Nonetheless, your Taser causes the
General to run off whimpering for a little while. But he keeps
randomly popping up. You have only five shots beforeyour
battery is dead.

90 the RAINBOW March, 1983
1 typed something a bit off-color the first time my Taser
quit. This didn't phase the program, which told me primly,
"Your French is not impressive." There is a subroutine
prepared (named ' &%$!' ()$%$! ! !) for a couple of other
"French" words you might happen to use. Like other
subroutines, or modules, it's introduced with a name —
REM, so unravelling the BASIC spaghetti into components
of the program is fairly easy, if you want to analyze it later.
In Final Countdown you're racing against a countdown, a
given number of turns before there's a rumble, the earth
opens, the missile launches, and bye-bye. You can ask:
SCORE? for how many turns you have remaining. "How
can you worry about points at a time like this?" the program
chides you — but it tells. There are three levels of difficulty —
Novice, Average, Expert, all menu-selected. Experts get less
time and more appearances of the psycho General, so it
remains playable against time and previous scores even after
you've "solved" it. You can QUIT at any time, but you can't
SAVE games part-way through for later resumption from
where you were.
There are no graphics, in a way disappointing, but what
can you "show" for the end of the world? And a modest
"NICE GOING" with your score is surely all the reward you
need for winning, what with your world-savior's glow and
all. Trumpets, Hashing screens, Presidential citations would
be, ah, overkill. By the way, don't expect any help from the
White House in this game. When you find and USE the Red
Phone— the White House hotline— a recorded message tells
you it's after working hours, call back the next day, after
doomsday.
A nice feature is the fixed-screen status window, protected
by a machine-language routine POKEd into the main
BASIC program. The window shows the "current scene"
and direction choices, and is updated to reflect the results of
each move you make, including taking objects. On the
"action screen." the two-thirds lying below the window, you
talk to the program and it answers you. The previous
commands and replies scroll upwards till they go behind the
window, so half-a-dozen previous moves and replies stay
visible. This is a great help in mazes and learning the routes
through the missile base. "INVentory" will tell you what
you're carrying at any time, at the cost of a countdown
penalty.
The General will suddenly pop up randomly in the
window, while you're busy reading or typing on the action
screen, below, and may not notice him. If you make your
next move without Tasering him, he's gotcha, that's it.
This "pop into the status window" technique is the
program's main formal novelty. Such an updating status
window is common on large business and word-processing
applications programs, and in the new $50 million Apple
LISA. In Adventures, though, it permits the use of random
game factors to which the player can immediately respond,
with varying results, an effect 1 hope to see other Adventures
use, as it adds a lot of interest. The usual random game
factor just knocks you out, handicaps, or (rarely) helps you
in a fixed way; there's nothing you can do about it, the
factor's outcome is predetermined in its effect on the game.
What the Cooks have done, in effect, is invent not a new
technical, but a new literary device. They use it here in a very
simple way, but later it can be developed with more
complexity (random factors interacting with and altering
screen-scene status; interacting with other game characters;
new forms of Magic). What it does — or can do — is add a
new dimension to what distinguishes computer games from
little books or short films — the interactiveness of the story
and you, the protagonist of that story.
The main program is in BASIC, so you can "cheat" by

PCLEAR before C LOADING. A backup program is
supplied on the cassette. The program is warranted against
defects for 60 days after purchase. 1 found a couple of
apparent bugs. Occasionally, the program would tell me,
"WOW! LOOK WHAT YOU FOUND!" But no matter
how much 1 LOOKed or EXAMined, 1 couldn't find out
what. Nor did various TAKEs or MOVEs, or GOs (with
different objects) produce anything but "NOT
R ELE VANT." Additionally, you can OPEN certain things
or EXAMine them when you're not really in their
presence — a kind of ESP view of them — though you can't
affect them unless you're there — a bug in the
OPEN/ EX AMine routines which makes it easy to cheat in
certain ways, but seems unintended.
In summary, an interesting game, with a unique focus on
taking risks to prevent war, rather than glorying in it.
Though if you blunder (as 1 did), you must shoulder the
responsibility for the nuclear destruction which follows,
giving rise to some philosophical reflections on peace
strategies, perhaps. (Although the General has it all set up to
go anyway, all you do is speed up the end a bit.)
After playing it a while, by myself and with a drop-out
priest who became an antiwar activist in the Vietnam era,
and is now a programmer punching COBOL most nights, 1
was a byte disappointed. 1 expected too much, probably, of
a game like this. I remembered hearing Father Daniel
Berrigan speak in 1981, after he and the others of the
Plowshare Eight had been convicted for entering the
General Electric Plant at King of Prussia, Pennsylvania,
smashing a number of Mark 1 2 A multiple nuclear-warhead
nose cones and pouring blood on them. Here's what he said:
"After much prayer and reflection, we
eight decided that it was here and now
for us. It was time to come down from
being teachers, priests, writers, etc.,
and try to do something which might n^ake
a modest real difference in the world.
"Our religious tradition offers to
life a slight edge over death, now. 1
often ponder what to say to be of help.
It might be something as simple as this:
Thou shalt not kill.
"Peace is something to be made,
constructed, hammered out, not an
ideology. It's very concrete, not a
theory. It almost needs a hammer, tools.
The government displayed a nuclear
weapon nose cone in our courtroom.
Looking at it was like looking at our
doomsday, like looking at the end of
the world."
By comparison with the real, slow-moving, often
disheartening moral adventures of quietly courageous
people, Final Countdown is, of course, trivial. But it's only a
game. In my view,.it's very preferable to a game in which the
player plays to destroy abstract worlds of abstract people,
using make-believe verbal and graphics devices not much
simpler to unleash-and-destroy-with than the real world-
killer weapons that politicians play with.
Final Countdown is as realistic in its way as are the
techno-war games it is a counterweight to. There are non-
game-players who really do these things. For the rest of us.

Analysis of Variance
A 'Nova' for CoCo
By Sam Sherrill
Manufacturers may install power into the computer,
but it is the programmer who gives it strength. And
while many have provided the games (and good ones,
too) for our amusement, programmers such as Sam
Sherrill have helped extend the basic capabilities of
our computer by developing its quantitative nature
through programs and tutorials related to statistical
analysis, science and education.
The author is on the faculty of the School of
Planning at the University of Cincinnati, where he
teaches research and statistics courses.
The purpose of analysis of variance (ANOV A) is to reveal
differences among samples that are not due to chance. The
usual procedure is to test the assumption that the samples
are alike. Statisticians call this assumption the null
hypothesis. They also label differences that seem unlikely to
occur by chance as statistically significant differences. Thus,
in the language of statistics, ANOVA is used to test the null
hypotheses.
If the null hypothesis is supported by the ANOVA results
then we may conclude that the populations from which the
samples were taken are also alike. For example, we could
compare examination scores among classes of students
exposed to different teaching methods to test the idea that
methods affect learning. The specific classes we select are
our samples. The null hypothesis would be accepted as true
when no statistically significant differences are found
among the exam scores for the classes. This means the
variation among the class scores is not explained by
variations among the methods we tested. In a more general
sense, this result also means that these methods are unlikely
to affect exam scores of all other similar students.
If the null hypothesis is contradicted by the ANOVA
results then we may conclude that the populations are
different. In our example, the null hypothesis that methods
have no effect on learning would be rejected since ANOVA
revealed statistically significant differences amongthe class
scores. We can conclude that variations among teaching
methods do help explain differences among class scores. We
can also conclude that these methods would produce
differences among other similar students.
ANOVA is an extension of the difference-of-means test
(DOM). The DOM test is used to compare two samples to
one another. (When just two are compared, an ANOVA and
DOM tests lead to the same conclusion.) The DOM test is
useful when we have specific hypotheses to test using two
particular samples. For example, we would use this test if we
expected one teaching method to produce higher scores than
another. Using ANOVA on all classes would tell us whether
there is a difference among them but would not identify the
source of the difference. In general, the ANOVA test is often
best suited for exploratory comparisons among three or
more groups while the DOM test is more appropriate for
specific pair-wise comparisons.
Exploratory comparisons often must be made among
samples of unequal size. If the classes in our example were
selected from a large population of such classes then it is
quite likely that they will not contain the same number of
students. ANOVA tests based on arrays (such as the one
offered by Bruce Douglass in the December 1982 issue of
80M/CRO) require equal sample sizes. The only way to use
this kind of program when sample sizes are not equal is to
"In general, the ANOVA test
is often best suited for
exploratory comparisons
among three or more groups... "
reduce all of the samples down to the size of the smallest one.
However, this also reduces the capacity of the test to reveal
differences. In addition, the memory demanded by this kind
of program grows as the number of samples or sample sizes
grow.
To avoid these problems, 1 wrote an ANOVA program
for the Color Computer that does not use arrays. Basically, 1
took the ANOVA formula for unequal sample sizes apart
algebraically and reassembled it in a way that uses running
totals instead: thus, any number of samples of either equal
or unequal size can be compared. This program requiresjust
over 3K of memory, regardless of the number of sizes of the
samples. It will run on machines with I6K and Extended

Color BASIC.
The program calculates the F-Value (the quotient of the
variance among samples divided by the variance within
samples) and the probability of that value occuring by
chance. It then compares this probability to the traditional
'significance levels of .05, .0 I, and .001 . When the probability
is greater than .05, the differences among the samples are
labeled as insignificant and the null hypothesis is accepted.
When the probability is less than .001, the differences are
labeled as significant and the null hypthesis is rejected.
Finally, when the probability of a particular value falls
between .05 and .001, the program indicates that the
differences may or may not be significant and suggests that
you may wish to withhold judgment on whether to accept or
reject the null hypothesis. By pressing any key, the program
then prints the usual results of an ANOVA: the total %
among, and within results for the sum of squares and
degrees of freedom; estimates of the among and within
variances; the F-Value; and, the probability of the F-Value
occuring by chance.

Word game enthusiasts take note!! This game pits you
against other players and a relentless timer while you try
to see how many 3, 4, 5, 6, or more letter words you can
make from the 10 letters chosen at random by the com-
puter. The more you get, the more you score, and you get
bonuses if you do well. All scoring, timing, and record
keeping is done by the computer. Sure the game is
educational, but it's so much fun you'll never notice!! TAPE
$19.95, DISK - $24.95
The most realistic fantasy role-playing game yet for the
Color Computer. You start out by rolling up your character's
basic ability scores and buying equipment. When you are
ready it's into the dungeon. Your character starts at first
level, but can rise in levels by garnering experience in the
fray. If you have role-played fantasy games you will be
amazed at the realism of the combat system. Armor class,
initiative, and damage by weapon type are all included,
with over 50 different monsters to fight - each with it's own
abilities. As you rise in level you can win treasure and find
magic weapons and spells - if you live" You set the game
length by telling how many monsters you want to fight
before you reach your final battle to the death against the
powerful Dungeon Lord. There are 1000+ place descrip-
tion combinations in this text based game, and real excite-
ment in every one 1 . This is a fantasy simulation, and is truly
not like any adventure game you have ever seen. For 1

64K Modification For D' Board
Both Easy, Inexpensive
By B. H. Alsop
Until now one had to either cut traces or buy a wolfbug
64K adapter card ($150) to convert your 'D' series CoCo
board to 64K. Here's how to do it for $2 over the cost of the
RAMs. Traces don't have to be cut and the modification can
be easily removed.
MODIFICATION
Purchase eight 16 pin dip sockets. Buy the type that will
plug into each other. Solder a small gauge wire into each
socket pin #9. Bend RAM 1C pins 1,8 and 9 upward for all
64K RAMs and insert them into the prepared dip sockets.
Solder the wire from socket pin 9 to IC pins 8 and I. Your
completed RAM socket assembly should look like Figure I.
Insert the completed assemblies into your CoCo RAM
sockets. Solderall pin 9s together with wire and connect this
bus to pin 35 of the 6883 SAM(UIO) with a series 33 ohm
resistor. Reconfigure the jumper block near the SAM to
16K. Remove the other jumper block. Solder a wire from
pin 12 of U4 (6821 PI A) to pin 17 of U8 (96821 IMA).
Now proceed with the F. Hogg modification as described
below
1 . Remove U 29 and U I I from their sockets. Bend pins 4,5
and 6 of U29 up. Bend pin 5 of U 1 1 up.
2. Connect pin 8 to pin 6 of U29. Reinsert both ICs.
3. Connect pin 4 of U29 to pin 5 of U I I. Connect a wire
from pin 5 of U29 to TP I. Insert version I.I BASIC ROM.
Note that no capacitor leads are cut. In fact, the
capacitors remain in the circuit to suppress power supply
noise.
To remove the modification, unplug the 1C assemblies,
unsolder a few wires and insert new 74LS02 and 74I.SI38
ICs into U29 and Ull respectively. »
PROBLEMS
The only problem encour
CoCo "[)" boards (like mine)'
soldered into the PC board
sockets. In this case, cut pin>
ered has been with very old
111 I and sometimes U29are
nstead of being mounted in
of U 1 1 Hush with the board
with a small pair of diagonal cutters. Bend the remaining IC
lead upward. Another 74LS02 is prepared and then
piggyback soldered on top of the existing U29. All pins
except 7, 8, 9, 10 and 14 are removed. Only pins 7, 8, and 14
are soldered to U29. Pin 9 of this added IC is soldered toTPI
and pin 10 is soldered to pin 5 of U 1 1 . See Figure 2. In this
case removal of the modification is only slightly more
difficult.
PERFORM ANC'E
I've installed five of these modifications on various
vintage "D" boards. Even a few "E" series boards have been
altered this way to permit easy removal for their owners.
When installed you don't know that you ever had a "D"
board CoCo. Good luck.

Making and Rotating
Rectangles
By Don Inman
Rainbow Contributing Editor
This is the sixth of a series of articles on the graphic
capabilities of Extended Color Basic on the TRS-80 Color
Computer. It goes beyond the material that was covered in
the book TRS-80 Color Computer Graphics.
Last month, we looked at a way to modify the output to
the video screen so that the display would conform to the
first quadrant of the Cartesian coordinate system. A method
was shown to scale the Y coordinate so that X and Y units
would appear to be the same length on the screen.
This article will continue using those techniques but will
restrict itself to a specific shape, the rectangle. We will
develop a very general program to define the rectangle in as
simple a way as possible. At the same time, provision will be
made to maintain flexibility when positioning the rectangle
on the screen.
PARALLEL RECTANGLES
A rectangle can be defined by two characteristics, its
height and its width. In developing the first stage of our
program let's limit the rectangle to one whose sides are
parallel to the X, Y axes. We can remove that restriction
after the basic program has been developed. If the length
and width of the rectangle are known, the X,Y coordinates
of one vertex (corner) determine where the rectangle
appears on the screen.
height
One input, the X, Y corner position, can be used to move
the rectangle left or right and up or down (called a
translation). Four pieces of information completely define
the placement of the rectangle. The following variables are
used:
XO = X coordinate of one corner position
YO = Y coordinate of same corner
H = height of rectangle
W = width of rectangle
The length and width parameters can be used in the
program to calculate the end-points of lines that make up
the rectangle in the following way.
X0,Y0+H XO+W.YO+H
H
X0,Y0 W X0+W,Yfl
The following subroutine will define the corners of the
rectangle. The lower left corner is PSET by DRAWSUB1,
and the four lines are drawn by DRAWSUB2. Subroutines
are used so that you may use them with any main program.

ESCAPE
A 3-D GRAPHICS ADVENTURE WITH SOUND
(Machine Language for Fast Action)
This is NOT the usual "find the treasure" adventure. In
ESCAPE, you are trapped on the top floor of a
skyscraper and the only way out is by using a very
unusual elevator. You must give the elevator the
correct code or else the ride down is a real killer. The
maze-like halls seem to come to life due to the fantastic
3-D graphics. Search the halls for rooms which contain
clues to the correct code. Clues must be deciphered to
learn the elevator's secret code. Game times depends
on the skill of the player, but it is typically 8-10 hours.
ESCAPE is suitable for group play. A mentally
stimulating experience.

You may want to place a rectangle on the screen in a
position that is not parallel to the axes of the coordinate
system. A basic knowledge of trigonometry is helpful at this
point. In this discussion and the modifications to our
original program that will follow it, the sine and cosine trig
functions are used. These functions are merely ratios of
certain sides of a right triangle in relationship to a given
angle of the triangle.

Suppose we start with a rectangle that is parallel to the
X,Y axes and rotate the rectangle about the lower left corner
by an angle A.
X2,Y2
X0,Y0
XI, Yl
i dotted line rectangle
i parallel to X,Y axes
solid-line rectangle
rotated through angle A
The lower left coordinates are the same as before, but the
coordinates of the other corners have changed.
First, consider the point Xl.Yl.
XI, Yl
opposite = Y1-Y0
X0,Y0 £
adjacent = XI- X0
The sine and cosine relationships become:
SIN(A) = opp./hyp. = Yl-YO/W
COS(A) = adj. /hyp. = Xl-XO/W
Multiplying both sides of each equation by W gives:
W*SIN(A) = YI-Y0 and W*COS(A) = XI-X0
Adding Y0 to the SIN equation and X0 to the COS equation
gives:
* Yl = Y0+W*S1N(A) and XI = X0+W*COS(A)
Therefore the X,Y coordinates of the new point can be
expressed in terms of the coordinates of the lower left
corner, W, and a trigonometric function. The Color
Computer can easily calculate these coordinates.
Now consider the next new corner (X2,Y2).
opp. = X1-X2
adj. = Y2-Y1
X0,Y0
106 the RAINBOW March, 1983
h rst.
S1N(A) = XI-X2 H COS(A) = Y2-YI/H Then.
H*SIN(A) = X 1-X2 and H*COS(A) = Y2-YI
And finally.
* X2 = X1-H*S1N(A) and Y2 = Y l + H*COS(A)
In a similar way. it can be shown that:
* X3 = X2-W*COS(A) and Y3 - Y2-W*S1N(A)
by changing only four lines of DEFRECTSUB in our
previous program, we can arrive at a program that will place
the rectangle at any angle and at any location on the screen.
Change lines:
2050 X1=X0: Y1=Y0: X2=X0+W*COS(A): Y2=Y0-
8*W*S1N(A)
2070 X2=XI-H*SIN(A): Y2 = Y l-.8*H*COS(A)
2090 X2=Xl-W*COS(A): Y2=Y 1 +.8*W*SIN( A)
21 10 X2=X0:Y2=Y0
Two lines are also added to the main program to input the
angle of rotation in degrees and to convert the angle to
radians. The SIN and COS functions in Color Basic and
Extended Color Basic require angular units to be radians
rather than degrees. If you wish, you may input the angles
directly in radians at line 150 and omit line 160.
Add lines:
150 INPUT "ANGLE IN DEGREES";A
160 A = A 57.295779
The revised program follows. Use care-in trre placement
and size of the rectangles that you draw. There are no
provisions in the program that will insure that all points will
be within the limits of the display. This is left as an exercise
for you.

Remember that old party game some of us called
"Consequences?" Each of a number (greater than two) of
people, seated round a table is provided with a slip of paper
on which s/ he must write a short story; for example:
(I) Napoleon met (2) Josephine on (3) the Isle of Elba.
(4) It was a desolate scene.
(5) He said: It is lonely here.
(6) She said: Don't despair!
(7) The consequence was: He returned to the mainland.
(8) The moral is: Never say die.
However, the whole point of the game is that at every stage
of the story the papers are passed round the table. The result
can be a hilarious jumble of stories with the oddest
characters and consequences!
Your CoCo can add to the fun of the proceedings by
offering a whole new series of permutations that are just not
possible in the pencil and paper version. To give a little spice,
the computer can assign a color code to every player (up to

Naked Gamer
If you think strip poker sounds like fun, read on.
Actually, the name of this program package is not
completely accurate. Only one player will end up com-
pletely undressed. These games are for the adventurous
couple!!
The two games are good by themselves, but in the right com-
pany they can be terrific. The first is called Strip Tails, and is
an arcade game played by two players simultaniously. You will
need quick hands on the joystick and a quick grasp of the tactics
to win, and if you lose, you could really lose your shirt. The other
game is called Sex, and is something like Mastermind". Both
the player and the computer choose a three letter word, and the
player has to guess the computer's word before the computer
can guess the player's.
At the end of each round of either game, the computer will in-
struct one of the players, by name, to remove a specific item of
their clothing. Don't worry, there isn't anything obscene in these
programs. (Remember, you are choosing a THREE letter word.)
On the other hand, the RESULTS from playing could be inter-
esting indeed, and the games are really good even if you elect to
keep your clothes on. Available on TAPE for $21.95, or on
DISK for $26.95. You will like these!!!

HOW TO HEAR AND THINK IN a SECOND LANGUAGE
Skilled linguistics have developed our series of second language programs. The lessons utilize the power of programmed
instruction wherein you are advanced to new material only after satisfactory learning has occurred at the current level. Our
techniques teach you how to think in a language without initially using any printed text material. No mental translation to your
native language is required. You learn as a child does, hearing and speaking before reading. The computer both tutors and
keeps track of progress as it moves you forward (or backward when review is necessary). AUDIO plus VISUALS plus
INTERACTIVE RESPONSE establish the learning process, and literally THOUSANDSof visuals help seal-in thesound patterns
of your new language.
All of our lessons are interactive and user friendly; yet, you are unaware of the complex course structure involved. For
example: Lesson SLU-1 uses the theme of PEOPLE, PERSONS & FAMILY to teach the use of nouns to name things, to classify
them into categories, and to identify members of a group. Sentence structure is developed using the verb 'be' and its relationship
to nouns and adverbs, including plural forms and inversions. Noun structure using definite and indefinite articles, and regular
and irregular plural forms is also presented. The other lessons are similarly designed. In addition, each VOCABULARY LESSON
presents approximately 200 visuals and 200 words that are integrated into the learning process.
While the foregoing might seem complex, and it is, IT IS ALSO THE REASON OUR COURSEWARE CAN TEACH
LANGUAGES. If you have tried 'game' or 'tape' language programs you know that they are ineffective. Our programs can teach
you a language because we have successfully combined expert authoring of programmed courseware with audio & visuals &
response & branching into a powerful tutorial package.

Software Review...
CoCo-Jot
A Thinking Person's Hangman
Computer Island has come up with an interesting version
of the spelling game "Hangman." It's called CoCo-Jot. Can
you figure out the hidden word (either three, four, or five
letters — your choice) within 10 tries? You start with 100
points and lose 10 for each try down to your 10th try and
zero points.
Since Computer Island is aiming at educational software I
wanted to try CoCo-Jot with my children, not only as a
teacher in a classroom setting, but as a parent might use this
program at home.
The well-done introduction of CoCo-Jot builds
excitement. However, the game is not as exciting. CoCo-Jot
requires an understanding that would take a teacher several
rounds to explain. The directions are too complicated for
young students alone to figure out. My children (first, fourth
and sixth grade students) were able to handle it on their own
after some coaching by me. My fourth grader finally said,
"Oh! It's like Hangman."
The game lets you type a word and then tells you how many
letters you got right. An alphabet list then lets you eliminate
letters you feel you do not need. Then you switch to a
"scratch pad" where you can play with the letters and try
various combinations. My children, on their own, turned off
the volume control as they did not like the constant "beep"
of the scratch pad. By a process of elimination, you keep on
guessing words until either you get it right or you get to the
10th try and the computer tells you the hidden word.
My first grader constantly referred to the word list
looking for words that had, or did not have, the proper
letters. This process will provide her with letter and word
recognition. But it requires one-on-one help with a great
deal of patience. She exclaimed "Thank goodness!"
(positive) when she got two letters correct on a three letter
word. She finally did get the word correct and she played
two more games on her own.
My fourth and sixth graders felt that the game was
difficult, but both said that they liked it and wanted to
continue playing.
There are some changes that I feel would help the game.
First, the lead instructions include a question for how much
"time" you want. This is misleading as the game is not timed.
The question is to randomize the word list. It would be
better to have said "pick a number from 001 to 9999."
Second, 1 found the sound in the"scratch area"annoying. It
should be eliminated, I feel. Also, my first grader, when
looking at the screen for choosing the word, counted five
periods ( ?) for a three letter word and was confused.
From my point of view, as a teacher and parent, 1 feel that
CoCo-Jot has potential to develop word and letter
recognition with students. The game comes with a word list
(but must be printed larger f or school use). A fine feature is
that the program can be modified with your own words and
therefore can be tailored to your needs. The game might be
more interesting if it were programmed in specific subject
areas (i.e., presidents, countries, math terms). Above all, the
game requires the most coveted of all educational goals —
patience and- thought, and to have an adult sit down and
develop a working relationship with their student or child.
Well, have you spelled "hug" with your child today?

Now that you know more about the hardware and
software which is involved, you may ask, what else can I
access besides large data bases which charge for the use of
their systems? The answer is a growing phenomenon called
the Bulletin Board Service. These are mushrooming all over
the United States. What isa Bulletin Board Serviceyou ask?
A Bulletin Board Service, or BBS for short, consists of an
individual with a personal computer and an auto-answer
modem set up to have outside callers access their computer.
(Yes, your own mini CompuServe!) Aside from the auto
answer modem, one needs special BBS Software to run the
system. For example, Spectrum Projects owns and operates
two BBS's which totally support the Color Computer. The
first system can be accessed by dialing (212) 441-3755. It is
operated and run on a Model III with four double-headed
disk drives. It has a disk storage capacity of 2.6 megabytes.
The system is free and no passwords are needed to access the
system. Some features of the system are a message retrieval
section, a downloading section, a merchandise section and a
Color Graphics section. Using a Smart Terminal Program,
you can dial into the system and capture files from the
download section. These files consist of games and utilities
which you can run on your Color Computer. Also, as an
added feature, color graphics can be accessed through the
phone lines right onto your TV set.
In the message retrieval section you can leave or retrieve
messages with other users of the system. It is a way to get
info on the Color Computer that is not readily available
through other channels. You can ask technical questions,
get opinions on Color Computer hardware or software, and
place an ad. In the merchandise section is a list and
description of products from the leading Color Computer.
The second BBS which is operated by Spectrum Projects
can be accessed by dialing (212) 441-3766. It will also be
accessed if you call BBS#1 and it is being used. It is switched
over from BBS#1 to BBS#2 via ringover. The second
Bulletin Board is operated on a Color Computer.
There is one last thing you can do with your modem.
Become a CoCo sysop! Sysop stands for system operator.
The minimum requirements to run a BBS on a Color
Computer are 64K of RAM, two disk drives, and an auto
answer modem. And of course, BBS software!
Bulletin boards have proven to be very profitable
investments, as yours truly can attest to. Just imagine sitting
in front of your CoCo BBS and watching it being accessed
by a complete stranger at any time of day or night from
anywhere in the world! Make way for the Bulletin Board
System — the wave of the future!

Ghostmania Puts You
In This Fascinating Game
On no! Not another Pac-Man game. It sure seems that the
Color Computer has been bombarded with enough Pac-
Man games, but this is one of the more original ones.
This game has you in the game itself, not looking down,
but in it, moving through walled corridors. Ghosimania is
slightly different f rom the arcade version. First, thereare no
pellets to eat, and instead of energizers there are blue
squares. While going through the maze the ghosts (thereare
about 30 of them) do not move until theyseeyou, thenthey
move at you. They gain points, which are displayed in the
upper lef t hand corner, as they move, up to 255 points. You
then run, if you have the chance, to a place where one of the
blue squares is under you. The computer then displays how
many more charges the pill has left, one to three. There you
wait until the ghost rounds a corner and runs into you. You
then get how many points he accumulated and one
POSITIVE ENCOUNTER. The ghost is then eliminated. If
you run into a ghost without being on a blue square you get a
NEGATIVE ENCOUNTER, and the ghost disappears.
After nine negative encounters the game ends. After a set
number of positive encounters, determined by the level, you
get a bonus game. The game has the fortunate option of
stopping the action and looking down upon the maze,
showing the ghosts, blue squares, you and the direction you
are facing.
The game can be played for practice without ghosts or
have the computer play. There are three skill levels,
Beginner, Intermediate, and Competition. There are 10
speed options.
The maze is player designed. There is an 1 1-digit number
displayed at the bottom before the game. The digits
determine where passageways start and end and where turns
go. For example, 99999999999 would be the easiest maze
while 33333333333 would be the hardest. Three is
recommended by the manual, as you would most likely be
confined in a small area and unable to get to some places.
The graphics I must say are the best I have seen in a game
of this sort. Fast machine code produces blue sky, green
hallways, an orange floor and very believable white ghosts
with blue eyes in a real-time environment. (For any of you
Chromasette subscribers out there who have the game
Amazing, the graphics are similar.) The program is written
in machine language, and, as such; is very fast. If you buy the
program, buy it for the graphics.
The game even has a monthly publication called the
Challenge List of high scores and competition events. You
receive a six-month subscription free when you mail in your
registration form.
The 1 1 -page manual is very good. It goes over every detail
of the game. No joysticks are required for this game and only
1 6K. According to the manual, the disk version requires 32K
and two disk drives. A game that requires two disk drives
must really be something! The cassette version is well worth
the price.

AT LAST! Help for the BASIC programmer. BASIC AID is an indespensable addition to the Color
Computer. It will save you valuable time and effort. If you write or modify BASIC programs,
you need BASIC AID.
You get 43 Common BASIC commands available as single Control Key inputs. Greatly
speeds up program entry.
A powerful feature is the ability to redefine any or all of the keys to your own specifications
PLUS you get invaluable features such as a MERGE command, Move Line command and
Automatic Line Numbering.
MERGE— Insert programs stored on
^ cassette into your Basic program.
You can even assign new line
numbers to the program you read
in. Great for creating your own
tape library.
^ MOVE— Lets you move and renumber any
part of your Basic program. GOTOs
and GOSUBs are automatically
changed,
Redefine any or all keys! Put in your most
— ^ frequently used commands. Then save
them to tape for use another time.

Software Review...
CCTHELLO: Well-Executed
Board Game for CoCo
CCTHELLO is a 16K Color Computer version of Othello
(traditionally called Reversi) designed for the Color
Computer. Othello is played on an 8 x 8 board, with two-
color pieces (normally white on one side and black on the
reverse). The object is to capture as many of your opponent's
pieces as possible. Each player alternates placing his colored
piece on the board in an attempt to outflank the other
player. When a single piece or group of pieces have been
outflanked, they are flipped to the opposite color. This
results in some dramatic changes as the game progresses.
Othello offers a range of strategic planning as well as
immediate tactical conflict.
The game, marketed by Spectral Associates, is well
designed for the Color Computer's graphic capabilities. It
should appeal to the beginning and intermediate Othello
player, hour modes of play are offered: three skill levels of
competition against the CoCo, and an additional two-player
option. This pits you against another human opponent
while the computer assumes the role of score keeper and rule
enforcer. CCTHELLO gives almost instant response due to
its machine language programming. The joystick input is
smooth and allows you to concentrate on the logic of the
game.
I have had experience playing Othello against several
different computers using a variety of programs. I learned to
play the game on a TRS-80 Model I usinga program written
in BASIC. It was very slow making moves, but offered a
good challenge to my inexperienced play. I next graduated
to a near master level program written by Dr. Peter Frey
from Northwestern University. His program, called
OTH EI.I.O V, was almost unbeatable at its highest level of
play. However, it required superhuman patience to
complete a game that could take hours on the TRS-80
Model I. More recently. I have been playing Othello on a
Lillith computer (a new scientific/engineeringwork station)
programmed in a Pascal-like language called Modula-2.
This version has very clever high resolution graphics as well
as challenging play. It has the kinds of features that really
improve your game, including options for suggesting moves
when it has you in a tough situation.
Until CCTHELLO came along, my only experience
playing Othello on the Color Computer was with a BASIC
version. It had a poor display and played a relatively weak
game. In contrast, CCTHELLO has a well-designed board
display that makes good use of the Color Computer's high
resolution color graphics capability. The game is
programmed in machine language for fast response, and the
levels of play are suited to both beginners and practiced
players.
Joysticks are required for selecting game options and for
moving the blinking cursor around the board to place game
markers. You alternate first moves with the computer. A
player always has light(yellow) markers while the computer
takes the dark (blue) ones. The game also makes good use of
sound to signal the moves. The score is continuously
displayed on the screen in colors corresponding to the
markers.
One feature of CCTHELLO, requiring some time to
adjust, is its nearly instant response. A beginner might find it
hard to visualize the consequences of his move before the
computer gives its response. It would be helpful if a delay
were built into the program so that a player could study the
board before the computer makes its move. Most versions of
Othello are slow enough that this usually isn't a problem.
Another problem with the game is in the two player mode.
While playing another human opponent, it is sometimes
hard to tell whose move it is. It would be helpful if the cursor
would change colors to signal which player, light or dark,
has the next move. This is particularly important when a
player is blocked from making a move. In this case he must
forfeit his turn. Without the cursor giving a cue, players
must wiggle their joysticks to see who has control.
After playing many games with CCTHELLO, I have
become familiar with its tactics at all three skill levels. I am
sure that a beginner would find the first level challenging
while learning the game. The third level will keep an
experienced player alert at all times. It takes only one small
mistake to turn the tables. Sometimes Othello can be that
way. A very even scoring game can look like a complete rout
when the final tally is made.
CCTHELLO is a well-executed board game for the Color
Computer. It makes a fine addition to computer libraries,
especially those with a tendency to become heavily
populated with endless versions of space invaders and other
reflex testing devices.

INTERNATIONALLY, THE
COCO movement is really beginning to
catch on. Actually, it is partly the Color
Computer and partly the Dragon-32 in
England and Europe. And, we
understand, there is still another look-
alike coming from the Far East with the
name Sampo.
An interesting aspect to the new
Color Computers seems to be that they
are doing very well in their "native"
areas. We keep hearing that Dragon will
come visiting the United States and
Canada (and the same for the Sampo),
but what is more interesting is that these
computers seen to be carving out nice
niches for themselves in theirownareas.
Add to that the increasing CoCo
influence overseas of Tandy itself, and
you end up with a growing CoCo
community that speaks many different
languages. This is easily seem by a heavy
increase in the number of copies of the
Rainbow we are selling outside the
United States and Canada. Those sales,
which in the last six months were not
inconsiderable, have now grown by 200
percent in the last couple of months!
Well, maybe some day RAINBOWfest
will have to have interpreters — but not
of the hardware variety. Oh well, we'll
all understand BASIC and Assembler,
too.
******
HAVE YOU SEEN SANDS of
Egypt, the new graphics Adventure
game from Radio Shack. This is not a
review, obviously, but we were
impressed by the game. Yet, it was not
the program itself which impressed us as
much as something else — a something
that was also spotted by reader Charles
Perrin of Huntsville, AL.
Sands of Egypt instructions tell you
that if you have Disk Extended Basic
1.0 you type in RUN "EGYPT'Xo start
the game. But, it adds, if you have
version 1.1, you type in DOS first.
All this is by way of saying that there
is a new DOS ROM for CoCo, and
there are, we hear, a new Basic and
Extended ROM as well. Its Basic 1.2,
Extended 1.1.
The new Disk ROM appears to be a
way to implement the OS-9 system you
have seen us talk about. You can use
this as an indirect call to the disk
operating system, or something like
that.
We hear that the new Basic ROM
fixes up some of the machine language
subroutines that sometimes caused
problems. And, it is our understanding
that the Extended ROM fixes the
problem we all had with the PCLEAR
instruction.
Could that mean that CoCo is getting
the final touches of its act together for a
real change — or maybe a big brother
sometime in the future. No, don't expect
anything to come along in the next
month or two along those lines, but we
do hear reports of a new VDG chip that
may be along soon.
Could the resolution be coming to
something like 700 by 500pixels? Could
there be a 64-character screen display
on the horizon? Is it possible to cram
4000 colors (that is not a misprint) onto
one chip?
Before anyone gets worried about an
outdated CoCo, we would like to point
put that historically, Tandy has never
obsoleted a computer. Even good ol'
Model I software is compatible with
Model III software. Or look at the
Model II and the Model 16 (and now
the 12). Software can, more or less, shift
between like systems. Sometimes there
are f ree or low cost upgrades. And, with
Tandy's new author's assistance
program, we see that practice
continuing.
Yes, CoCo is here to stay. Why, even
Wayne Green, who predicted the total
demise of the Color Computer a year
ago, is trying to get into the act.
******
NOT ONE MISTAKE, but two to
report to you. You may have inferred
that the Spectrum Light Pen and the
Light Pen Fun-Pak were both available
from either Spectrum Projects (which
markets the pen) and from Computer
Island (which wrote the software). Not
so, the whole package is available only
from Computer Island (Dept. R, 227
Hampton Green, Staten Island, NY
10312) for $34.95. The Fun-Pak sells
separately for $14.95. And, yes, it was
an error in the Spectrum advertisment
which showed the CoCo Cooler for
$19.95. Correct price is $49.95. Both
misprints are our fault, and weare sorry
if they caused you problems.

NELSON SOFTWARE IS OUT
with one of the nicest-looking packages
we've seen for their new Super "Color"
Library series of programs. They have
added to the Super "Color" Writer II
and Super "Color" Terminal programs
called Calc, Database, Mailer, Speller
and Disk-ZAP. All come in handsome
brown loose-leaf bindings with gold
stamping. And, by the way, Super
"Color" Writer II is into version 3.0
now, with high resolution display
screens. This is also true for the new
Terminal program.
The Calc program is a "what if?"
spreadsheet; Mailer is a mail merge and
correspondence program; Database is
an electronic file and Speller is, of
course, a spelling checker with 20,000
words.
******
SPECTRAL ASSOCIATES
TALKS TO you with a new high-
resolution machine language game that
incorporates words. Android Attack is
available now and gives another
difnension to CoCo that, we are sure,
others will be using in the future.

CORES-64 FROM CER-Comp is a
new tape-based editor/assembler that
can be run in any CoCo from l6to64K.
A total of 59K of work space is available
with the 64K version. It does not require
a disk or FLEX to run the 64K version.

Like To Live Dangerously?
Minefield's A Blast
Software Review...
Tower of Fear: Despite
Death, A Fun Adventure
Those among us fortunate enough to have avoided actual
combat will be able to enjoy Minefield, a game simply
conceived, yet challenging enough for the most seasoned of
computer war-game veterans.
The object, of course, is to cross an area that has been
peppered with hidden mines by the enemy. There are 10
levels of difficulty, but, believe me, none of them is easy.
After you CLOAD the cassette, the computer requires
several seconds setting up the mine field, sounding short
beeps as each mine is placed. Those of you without joysticks
will be glad to know that the game uses the arrow keys to
negotiate the course.
You'll be even happier to know that you are provided with
a mine detector that sounds once foreach mine touchingthe
invisible square that you occupy. It tests all four sides,
including the corners, so there are eight possible locations.
However, the mine detector doesn't tell you the exact
positions of the mines. So, even with a warning, you are
never out of danger. Step on a mine and you are blown to
smithereens!
If you're lucky enough to make it through the mine field
alive (I never have), your score is contingent upon how many
moves are required, as well as the difficulty level. While any
mention of mine fields usually brings to mind someone
gingerly stepping along trying to avoid triggering the
notorious and deadly "Bouncing Betty" or Claymore
antipersonnel mines or maneuvering heavy equipment past
antitank mines, the most destructive of all, the term mine
dates back to the time when soldiers would actually mine
tunnels underneath enemy trenches and forts, then pack
them with gunpowder and BOOM. During the Civil War,
the Union forces tunneled under the Confederate
entrenchment at Petersburg, Virginia, and blew such a hole
that the engagement is now known as the Battle of the
Crater.
As you play Minefield, you are reminded of the terrors of
war and should be able to empathize with those among us
who have experienced the feeling of possibleextinction with
the next footstep. Melodramatic? Perhaps, but it is one of
the things you experience as you enjoy the game.

Tower o f Fear is a moderately difficult word adventure. It
has death (1 got killed at least three different ways),
treasures, and several surprises. This adventure takes place
in Graylockland at the castle of the late Blackheart
Firethrower. That is, if you can get into the castle, ha ha.
Blackheart Firethrower's castle has been inhabited by
wraiths and Cyclopes for the past three hundred years. No
one, Sir Adventurer, has ever returned with even one of
Blackheart's valuable treasures.
With excellent assistance from my wife, I was able to find
all the treasures in four orfive hours of playing time. I found
all the treasures by using imagination, courage, skill(?),
magic, and luck. I found it certainly doesn't pay to go
wandering aimlessly around in a maze of corridors. It seems
the unfriendly Cyclopes kill first and ask questions later.
Tower of Fear has a couple of nice features I really like.
One is that about six seconds after the program starts
loading a graphic title page is uncovered line by line. The
other feature is that during play the screen uses reverse
video. This makes a much more interesting and easy to read
screen. The one- and two-word commands used in the game
are not dissimilar from any other word adventure.
The game is written for 16K and is in machine code. I was
somewhat disappointed in the documentation for the game.
The single sheet of paper that came with the cassette
provides the setting for the adventure, but gives no
information on how to play the game. Therefore, I would
not recommend this as a first adventure, but if you have had
some experience with word adventures, then I'm sure you'll
like this one. Another complaint I have with the
documentation is it gives you instructions to CLOAD the
tape, but since it is in machine code you have to CLOA DM
it.
One other problem I had was that I could not successfully
save a game in progress. After making a couple of calls to
Bob Little of The Programmers Guild I found out the
problem. When saving a game you have to use eight
characters for a file name or the program won't recognize
your data file.
All in all, this is a fun adventure game. I recommend it.

Hard Copy Your Diskette
Listings With Style
By Michael Plog
the
on
RAINBOW
7- -V
The basic idea of this program is to produce a printed
copy of the directory listings of your diskettes. This task
could be accomplished reather easily by POKEing &HFE
(254 in decimal) into location III. This controls the output
device code, as reported in the Rainbow, August 1 982, page
29. The POKE procedure, however, only prints what would
appear on the screen, and does not have a very
"professional" look.
The program discussed in this article prints two directory
listings across the page, includes any "killed" files, tells the
beginning Granule of each file, and even prints out the file
allocation table, so you can visually track yourfiles. Figure I
shows what the program produces.
In the upper-left corner of Figure I is the title of the
diskette. You must input the title every time you run the
program. I use the Line Printer VII, so I put the title in
double wide letters by printing CHR$(3I), the title, then
CHR$(30). You can dress up this part any way you want.
The double heading right below the title explains what is
to be found in the table.
"Name" refers to the name of the
file, as recorded on the diskette.
Any file name starting with a number
sign (#) indicates the file has been
killed, but not written over. (If

you wish, you can try to recover
this file.) For example, note the
first listing in the right column;
it demonstrates a killed file.
"Ext" is the extension name
listed on the diskette.
"Type" refers to the file
type: 0 means a BASIC program; I
means a BASIC data file; 2, a
Machine Language Program; and 3
a Text Editor source file. (Refer
to your Disk Owner's Manual.)
"ASC" refers to the storage
mode of the file. A "B" indicates
binary format; "A" is ASCII format.
Under the "GRANULE" heading,
"NUM" is the number of Granules
in the file. "ST" indicates the
start, or beginning, Granule.
( More on this later.)
The number of free granules is printed following the

listings of the files. This number may be misleading. If you
have erased some files, the number of free granules may not
reflect this.
At the bottom of Figure 1 is the File Allocation Table.
The top row of numbers is a counter, for the sixty-eight
granules of the diskette, numbered from 0 to 67. The bottom
set of numbers indicates the contents of each byte of the File
Allocation Table, in ASCII format (not Hex format). The
numbers are to be read from top to bottom, in a single
column. For example, byte 0 (the first one) of the File
Allocation Table contains a "255." The meanings of the
numbers contained in the File Allocation Table are:
255 The granule is not part of a
file: it is a "free" granule.
9 through 67 The granule is used
as part of a file. The number
tells the next granule of the same
file. For example, the number in
byte 30 is "31." This means
that granule 30 is part of a file
and granule 31 is the next granule
of the same file.
back to the numbers listed under GRANULE, in the ST
column. This number shows the first granule of each file.
Now, look at the number in that corresponding byte of the
File Allocation Table. For example, the first program listed
in Figure I is A D-DICT. The program begins on granule 32,
and uses one granule of the diskette. In the File Allocation
Table, byte 32 contains a "196. "That means that fourof the
nine sectors are used for A D-DICT. Hangman starts in
granule 26. The second granule of the file is 27 (this is found
from the file allocation table entry for byte 26). The last
granule of the file is 24, and the 198 means that six sectors
are used and the remaining three are unused.
The File Allocation Table, as printed in Figure 1, allows
you to visually track all the files (programs and data) on the
diskette.
The Disk Owner's Manual gives some explanation of the
File Allocation Table, and the reader is encouraged to
examine the manual.
It is possible, of course, to print (to the screen or paper)
each byte of any file contained on your diskette. That,
however, is a subject for a future article. (Or for your
experimentation.)
193 through 201 — This granule is
the last in a file. Subtract 192
from the number to learn how many
sectors of this granule are part of
the file. For example, a "195"
means that three of the nine sectors
are part of the file; six sectors
are unused.

The Platinum

...programming Made Easy
FULL SCREEN EDITING OF
BASIC PROGRAMS
With the PLATINUM WORKSAVER'S
editor, there's no more counting the
numbers of characters to delete or
change, orwondering if you deleted
too many or too few. You see the
whole line as it's edited. Changes,
deletes and inserts are automatic
and the cursor can be moved any-
where on the screen.
FULL SCREEN EDITING OF
NUMERIC AND STRING ARRAYS
But that's only the beginning! The
editor (Written in machine language)
also comes with a short, two line
BASIC subroutine that will allowyou
to use the full screen editor on your
numeric and string arrays. This is the
springboard you need for develop-
ing your own VisiCalc™ or word
processor.
SINGLE KEY ENTRIES OF
BASIC WORDS
So, the PLATINUM WORKSAVER
makes it easier to write useful pro-
grams and edit them, but that's not
all! Entering programs is a breeze
with single entry of over 80 basic
words, on a beautifully designed
KEYBOARD OVERLAY, color-keyed
to function. No need to memorize or
consult a conversion chart to find a
word.
PROGRAM CHAINING AND
DYNAMIC DEBUGGING
Nowyou can write, enterand change
programs easily, but what about de-
bugging? This is the frustrating, time
consuming aspect of programming
and frankly, the Color Computer
doesn't help you much . . . you have
to start the program over each time
you make a change. But not with
the PLATINUM WORKSAVER!! With
it you can change, delete, add and
rearrange or join lines. The special
reserved key is excellent for copying
or moving parts of lines to other
lines . . . plus, you can even LOAD
A WHOLE NEW PROGRAM without
disturbing the data you've created.
NUMERIC KEYPAD
We've solved another Color Com-
puter weakness. Press a control key
and letters J, K, L, U, I, O, P become
number keys 1-7. Numbers 8-0 re-
main in their normal positions. The
keypad numbersareclearly labeled
on the overlay.

Create A Tape Register
By Joseph Kolar
There is light at the end of the tunnej! Now that you have
your cassette tapes organized, there is one final household
chore to get out of the way.
You are about to create a tape register. The definition and
scope of the tape register will become self-evident as you
proceed. On the outside cover of the notebook you were
asked to purchase, stick two strips of labeling tape (neatly
centered!). With a black, felt-tipped pen, neatly letter "tape
index" or "tape register."
Open the notebook, and fold it so that you can rule lines
on the inside cover. Draw a horizontal line about one inch
below the top, across the inside cover, using a black, felt-
tipped pen. A half-inch below that line, rule another line.
About 1 Vi inches below that, rule a line. A half-inch lower,
rule another line.
About one inch lower, rule a line. A half -inch lower, rule
another. About an inch and a half lower, rule a third line.
Count up three lines. Make a vertical line, about the width of
a ruler, from the left margin and connect the three bottom
lines. Make a second vertical connecting line about the
width of tr|e ruler, from the last line you drew. About 1 Vi
inches from the right edge of the notebook, rule a third
connecting line.
About an inch below the last line you ruled, rule as many
lines as space will allow, about a half-inch apart,
horizontally, until you reach the bottom of the page. About
a ruler's width from the left margin, draw a vertical ruled
line, connecting the series of lines that you ruled
horizontally.
Using a red, felt-tipped pen, neatly center and print "tape
index" or "tape register" between the top two lines. Between
the third and fourth lines, print "format." Drop down to the
next two lines, which are broken into four segments. With a
regular black pen, in the left box, print "name." In the next
box, print "comments." In the third, largest box, print
"description" and in the right-hand box, print "evaluation."
If you have about ten boxes in the bottom portion of the
inside cover, you are in business. Into the small area to the
left, copy the first part of the following li st, and in the large
area, copy in the explanation. Of course, you can improvise
your own list that best conforms with your system.

You will notice 12 categories listed. You may choose the
ones you need or add others.
With a black, felt-tipped pen, beginning at the first page,
in the lower, right-hand corner, print "A." Flip the page over
and in the lower left-hand corner, print "A." Print "B" on
both sides of the next sheet and continue through "Z." Letter
the next nine sheets "I " through "9" on both sides in a like
manner.
Return to page "A." A ruler's width from the red printed
Hne, rule a vertical line from the top blue line to the bottom
blue line. A ruler's width from the right edge, rule a second

line. Do the same to all the pages that you lettered or
numbered. For now, you need only to rule the right-handed
pages. At your option, draw a line in black ink over the top
blue printed line. It doesn't cost anything and gives it a
finished appearance.
Congratulations! You have just completed your personal
index.
For the sake of argument, say that on side two of your "B"
labeled tape, you have a program named Quadstar. It is a
space war type game that has hi-res graphics with sound and
you may use either joysticks or arrows on the keyboard. It is
an excellent game but you have to PC LEAR to g^t enough
memory.
Turn to right-hand page "Q." On the top line, in the box
that corresponds to the "name" box under "format" on the
inside cover, print in black ink Quadstar. On the line
underneath it, in red ink, print the address, "B2"(tape B, 2nd
side). In the next column, put a "*" because it is hi-res
graphics. Next to it put "S" to designate sound. (Sometimes
you forget to turn up the sound!) Underneath, in the same
column, put "JS/K" to indicate that joysticks or the
keyboard are optional. In the next column, write in "space
war game" and some other comments of your choice that
you deem necessary. At the end of the second line, print
PCLEAR. In the last column, print your evaluatin of the
program. In this instance, it is "excellent." Finally, rule a
black line over the blue printed line under the second row, to
close out the entry.
You can use designations such as "super," "good," "very

somebody else's. Any program that you figure is "lousy"
shouldn't be CSA VED. There is no need to clutter up your
personal library with junk.
Go through all your tapes and enter them into the index.
You may have to CLOAD and RUN some of the programs
because you have forgotten what they wereabout. Onceyou
have all of your programs listed and written up, you will
have saved a lot of head-scratching.
You have finished your arts and craf ts workout. It was fun
to do and now your system is operational. Once again,
contratulations!
Henceforth, you will be doing a lot of program
transcribing. Here is a hint that will help you.
When keying in a long program, put a "scratch tape"into
your cassette, (temporary storage), rewind it and set it a few
counter numbers after the last program on the tape. Ideally,
you should use a fresh tape, rewind it and reset the counter
and run it (fast-f) to 003. You will be ready to transfer your
work at a moment's notice if you are interrupted for
whatever reason and must shut down.
Put a penciled tick mark next to the last line number that
you listed before the interruption. Using a blank cassette
index card, write in the starting counter number, a
temporary program name and after you CSA VE what you
completed, the ending counter number. S kip some counter
numbers and make a second copy. You can CLOAD the
program at a later time and continue. Do this as many times
as necessary until you get a compelted program and CSA VE
it twice elsehwere in your tape library. Finally, erase both
the temporary storage tape and the penciled notations on
the index card, and the temporary storage tape is ready for
its next mission.

Stinger Bee-neath
Reviewer's Expectations
Picture yourself as a bee catcher about to enter a hive of
honeybees with your mission to catch as many honeybees as
possible without being attacked by the killer bees in the hive.
That's the plot in this new arcade-style game, Stinger, f rom
Spectrum Projects.
As the game starts, you look down into the hive, which is a
maze of concentric circles with the head of the queen bee in
the center. The principal difference between this game and
all those other maze games you've been playing is that the
position of the openings in thecirclesis constantly changing,
making it appear that the hive rotates along with your bee-
catcher, the bees, and the killer bees.
Now to grab that joystick and start to play. Better re-read
those instructions, because you start on the periphery of the
hive and to move inward you must move your joystick to the
left, even if the opening is to the right! Then quick, re-center
that stick so that you can stay in the circle and grab some of
those "X" shaped things which are the honeybees you want
to catch.
What's the diamond-shaped thing about to hit me? Must
have been a killer bee, because the low buzzing noises just
changed as he got me. No matter, a quick check in the upper
lef t shows I 've got five catchers lef t — got to be more careful
this time!
I'm doing great, catching bees like fury, when —
annoyance! I come upon one fellow who won't let me grab
him. Now I know what the directions mean when they say it
may happen that I will pass over a bee and not catch him. I
consider this a major flaw.
Now, what's this? Everything is speeding up like mad and
I'm still on Level I. That's right; this is one of those games
where the fewer the objects on the screen, the faster
everything goes. Here's where joystick control is next to
impossible. More by chance than skill, I manage to get all
the honeybees, and even a time bonus. No cute picture
appears between screens, and the game repeats.
The very detailed instructions which come with this game
say that after Level 3 the queen may have a surprise for us.
Although Stinger was given a thorough weekend testing by
my children, ages II and 13, and their friends, ages 9 to 13,
I'm afraid none of us have yet been able to master the
joystick after the game speeds up toward the end of each
screen.
There was a great deal of "I wish..." going on. "I wish I
could move backwards." "1 wish there were cute bee
pictures." "I wish there were more sound effects." "I wish I
could move the joystick the direction I want to go."
All in all, although the circular maze and changing
openings make this different, we gamesters expect more
sophisticated use of graphics, sound and the joystick
controls than this game provides.

Can You Deactivate
The Bomb?
By David A. Stewart
This is a game of chance. You must guess the correct code
in order to deactivate the Atomic Bomb and keep everyone
from being blown up. Since the computer is generating the
number on a random basis, you can never memorize the
winning numbers.
It's a simple game that my children love to play. I think
other Color Computer users will enjoy it, too.
Line Description:
Lines 95-135 print the instructions and set the mood for
the game. I used the INKEY function throughout the
printed material so that you can read it at your own speed. If
you prefer to skip the instructions, just continue to press
ENTER until "ENTER YOUR COMBINATION?"
appears at the top of your screen.
Lines 150-1 75 are the GOSUB statements which send you
to the random selection of numbers sub-routine. There are
five of these lines, which gives you five chances to guess the
combination.
Line 177 sends you to line 195. This line is only applicable
if you have not guessed the combination.
Lines 180-191 are the WIN routine. It also lets you decide
whether or not to play again.
Lines 195-965 are the LOSE routine.
Line 970 sends you to line 187 where you can choose
whether or not to play again.
Lines 1500-1530 are the random generator of the
combination.
Lines 200 and 2050 are time delays.
User Modification
If you wish to have more chances at guessing the
combination, simply add more lines between lines 150 and
177 that say "GOSUB 1500." If you want less than five
chances, delete some of the lines that are already there. You
should also change the last part of line 135 from 'You have
five chances...' to read the actual amount you are giving
them.
If you wish to make it more difficult in another manner,
you can change the amount of numbers the computer can
choose from. In this listing, the computer will pick a number
between I and 10 at random. For example, if you wish to
make it pick a number between I and 25, you would change
line 1520 to: "If X=RND(25) then 180." Then you would
change line 135 to read. .."it is a number between I and 25."
If you make the number span too large, you may find it very
hard to win with only five chances, so you might want to
increase the number of chances at this point.

Soflnare Review...
Revolution Rolls,
Despite A Few 'Rough Spots'
Have you ever wondered what it would be like to drive a
race car? Picture this: a car built for speed, no pollution
control devices, and a total disregard for the EPA mileage
ratings. 1 don't know about you, but 1 have always wanted to
get behind the wheel of one of these cars and let 'er rip. Most
of us will probably never get the chance to live out such a
fantasy, but with a little imagination you can come close.
Revolution is a game in which you race against the clock
in order to record the fastest lap time. It is much like
qualifying for a race, because each lap around the track is
timed separately. The graphics are similar to those of the
arcade games that 1 have seen. The track moves from side to
side, has straightaways and zig-zags, and you have to keep
your car on track by moving your joystick left and right. If
you go off the track you do not crash, but arc slowed down
until you get back on course. You can also vary your speed
by moving the joystick forward and backward. In addition
you have your choice of four cars in which to race, as well as
many different tracks on which to qualify. Revolution also
keeps track of the best times on all the tracks and records
them on disk so that your best times are not lost when you
end the program.
Playing Revolution is easy. First you select the car you
wish to drive. Then you choose the track you want to qualify
on as well as the number of laps you want to run. After each
race, your average lap time and your best lap time is
displayed. If your best lap time is a track record, you are
then asked to enter your name for the records. At this point
you can change cars or try anothertrack if you like. The cars
in Revolution are a VW (do I detect laughing out there'.'), a
Porsche, a Ferrari and a Lotus. Each of these cars has its
own speed and handling characteristics which are not only
very different, but seem very realistic (not that 1 would really
know).
When you get tired of racing on the tracks that are
provided you can design your own. To do this, you first
select the difficulty level of the track. The difficulty level
determines how wide the track is. This can vary from very
easy to almost impossible. You then map out the track by
moving your joystick from left to right to form sweeping
curves, straightaways, or whatever. After your track is done,
you are given a chance to race on it bef ore you have to decide
whether or not to save it to disk.
Revolution has good graphics, but 1 would have liked
some additional things on the screen such as road signs,
scenery or the like. 1 also feel that the sound effects could use
some improvement. These drawbacks led me to tire of the
game after about one hour. The documentation supplied
does a good job and, in f act, is better than that supplied with
most games 1 have seen. Without getting into a whole
discussion on the issue of software piracy, 1 do not feel that
this review would be complete without making mention of
the fact that you cannot make a backup copy of the disk that
is supplied. If your disk system is like mine and occasionally
wipes out your directory, it will cost you $4 to get a
replacement disk. To me this is a very serious drawback.
All things considered. Revolution is a good program.
With a few improvements however, it could be an excellent
program. If you Have racing in your blood you should
consider taking it for a spin.

MACRQ-BQC
The Micro Works is pleased to announce the release of
its disk-based editor, macro assembler and monitor, writ-
ten for Color Computer by Andy Phelps. THIS IS IT — The
ultimate programming tool!
The powerful 2-pass macro assembler features conditional
assembly, local labels, include files and cross referenced symbol
tables. Macro-80c supports the complete Motorola 6809 instruction set in
standard source format. There are no changes, constraints or shortcuts in
the source language definition. Incorporating all of the features of our
Rompack-based assembler (SDS80C), Macro 80c contains many more
useful instructions and pseudo-ops which aid the programmer and add
power and flexibility.
The screen-oriented text editor is designed for efficient and easy editing of
assembly language programs. The "Help Key" feature makes it simple
and fun to learn to use the editor. As the editor requires no line numbers,
you can use the arrow keys to position the cursor anywhere in the file.
Macro-80c allows global changes and moving/copying blocks of text. You
can edit lines of assembly source which are longer than 32 characters.
DCBUG is a machine language monitor which allows examining and
altering of memory, setting break points, etc.
The editor, assembler and monitor — as well as sample programs —
come on one Radio Shack compatible disk. Extensive documentation
included Macro-80c Price: $99.95
YOU NEED
COLOR FORTH!!
Why?
•Forth is faster to program in than Basic
•Forth is easier to learn than Assembly Language
•Forth executes in less time than Basic
Forth is a highly interactive language like Basic, with
structure like Pascal and execution speed close to
that of Assembly Language. The Micro Works Color
Forth is a Rompack containing everything you need to
run Forth on your Color Computer.
Color Forth consists of the standard FORTH Interest
Group (FIG) implementation of the language plus
most of FORTH-79. It has a super screen editor with
split screen display. Mass storage is on cassette.
Color Forth also contains a decompiler and other aids
for learning the inner workings of this fascinating lan-
guage. It will run on 4K, 16K, and 32K computers.
Color Forth contains 10K of ROM, leaving your RAM
for your programs' There are simple words to
effectively use the Hi-Res Color Computer graphics,
joysticks, and sound. The 112-page manual includes
a glossary of the system-specific words, a full
standard FIG glossary and complete source listing.
COLOR FORTH THE BEST' From the leader in
Forth, Talbot Microsystems Price: $109.95
SOFTWARE DEVELOPMENT SYSTEM
The Micro Works Software Development System (SDS80C) is a complele 6809 editor, assembler and
monitor package contained in one Color Computer program pack' Vastly superior to RAM-based
assemblers/editors, the SDS80C is non-volatile, meaning that il your application program bombs, it can't
destroy your editor/assembler. Plus it leaves almosl all of 16K or 32K RAM tree lor your program. Since
all three programs, editor, assembler and monitor are co-resident, we eliminate tedious program loading
when going back and lorth Irom editing to assembly and debugging 1
The powerlul screen orienled Editor features finds, changes moves, copys and much more All keys have
convenient auto repeat (typamatic) and since no line numbers are required the full width ol the screen
may be used to generate well commented code
The Assembler features all ol the following complete 6809 instruction set: conditional assembly: local
labels: assembly to cassetle tape or to memory: listing to screen or printer: and mnemonic error codes
instead of numbers
The versatile monitor is tailored tor debugging programs generated by the Assembler and Editor. It
features examine/change ol memory or registers, cassette load and save breakpoints and more. SDS80C

Corrections
StanPeppenhorst's "Make Authoritative Decisions With
This Situational Model," (Feb., 1983, page 132), had two
REM statements in Lines 10 and 20, both of which landed
on our "cutting room floor" by accident. REM statements
don't affect the way the program runs, right?
Wrong. Many of the subsequent lines in the program have
a GOrO70attheend ofthe line. Hard to do with no Line 10.
The correction is simple. Just add a line 10, such as:
10 REM VROOM
Or, you could change the several GOTO 10 statements to
read GOTO30.
Ted Blatt reports the program included in his article,
"Print Those Print Statements With This ML Feature,"
which appeared in our last issue, has an added feature you
probably do not expect — or want. While it will change the
PRINT statements to PRINTW-2, statements as advertised,
it also puts a #-2 on LEN statements.
To rectify the problem, change Lines 1 40 and 1 50 and add
Lines 142, 145, 148 and 149, as indicated below:

With the additional DA TA lines, you will need to change
the number 16308 (in lines 60 and 100) to 16350. The pro-
gram itself is in BASIC, but generates a machine language
routine which should be saved to tape and used when the
utility is implemented. Prior to CLOADMing the machine
language version, you should CLEAR 350,15999.
Errors also appeared in the "Unidatfl" program in
December, page 120 and 123. Here are those corrections:
Delete Line 140 and Lines 1800-2060 inclusive
Delete Line 5030
Line 5035 should read: PRINT@230, "o — open new file";
Line 5040 should read PRINT@262, "e — exit to basic";
These lines eliminate the sort function and clean up the
screen display.
J.D. Ray writes that in his "Income Tax History" in oiir
February 1983 issue, page 148, you might get an ?FC
ERROR message. The problem will only occur if the range
of the figures in the data statements are such that the
program cannot adequately decide which graph to use. The
following additions and corrections should solve any
difficulties.
611 IF A>15 OR B>15 OR C>15 OR D
>15 OR E>15 THEN B-15 ELSE B-8
630 IF G<9 THEN GOSUB 970
M.P. Wilson, whose "Rairldex" program was published
in the January issue, reports that he has received several calls
about an ?OM ERROR in Line 20. The program was
written for 32K ECB, not 16K as we mistakenly noted. Even
then, says Wilson, it requires a POKE25,6:N EW.
For those with 16K, he suggests the following: Before
loading "Raindex," do the POKE25,6:NEW, then reduce
the size of the CLE AR15000 and change the size of the array
(same line) until the error goes away.
In Burton B. Witham's "Who Knows All Those Callsigns?
CoCo Knows!" (Rainbow February 1983) Lines 180 thr-

Software Review..
As Arcade Battle Game,
Defense Is Strikingly Good
Perhaps in keeping up with thetimes, Spectral Associates
should have named their new program "Dense Pack"
instead of Defense. This game is very similar to the popular
arcade game in which you must defend the friendly cities
from a nuclear attack.
In Defense, instead of defending cities, you defend
outposts. The game instructions claim that you are
defending them from a laser attack, but everyone knows that
lasers travel at the speed of light and those are really
warheads streaking across the screen trying to annihilate
your ammo supply and the outposts which you are
attempting to defend.
There are three outposts on each side of your main
defense base where your ammo is stored. In addition, there
are two extra ammo dumps which you can call upon if you
run out. The play starts with the enemy "lasers" beaming
slowly down onto these targets. Your defense is to fire your
laser, which you direct with a joystick controlled cross hair,
in front of the downwardly plummeting beam. Your laser
blast causes an explosion at the location of the cross hairs
which destroys the incoming beam if you are lucky enough
to have engulfed it in the blast. This blast lingers on the
screen long enough so that if you place it in a strategic
location you can destroy several incoming beams. In the
early stages of the game you have a luxurious supply of
ammo but good gamesmanship dictates that you use it

conservatively because part of the scoring comes from how
much ammo is left in reserve after an attack is over.
In any realistic depiction of a battle of this nature, the
object is to see how many of the enemy you can take with
you before you are destroyed. The attacks occur in waves.
After a wave, if any of your outposts have survived you are
resupplied with ammo. After every other wave, the level of
intensity of the attack increases in both the number and the
speed of the incoming "laser beams." At the higher levels,
you are subjected to not only the beams streaking across
your defense screen but to "flip charges" and "buzz bombs."
These weapons are very difficult to defend against because
they apparently have some type of radar built into them that
senses your laser blast and attempts to outmaneuver your
defenses. It requires a very accurate shot to destroy these
devices.
Points are scored based on the number of beams, charges,
and bombs that you stop on each wave as well as the number
of outposts and amount of ammo that is left. For each
10,000 points you receive a bonus outpost.
Defense is a very fast machine language program that
requires 1 fSK and joysticks. With few exceptions, this game
plays like the "missile"arcade game. The graphics display, in
multi-color high resolution, is good. The author has built in
the ability to toggle between color sets during play by
pressing a key. Sound, except as noted below, is integrated
very well into the play of the game. The progression of play
in terms of difficulty is excellent and will not frustrate first
time users. Joystick response is quick and accurate.
I believe that Defense is a good piece of software, and
would make an excellent addition to any Color Computer
game players library. The author has thought about the little
things that are often overlooked but make the difference
between a good and a great game. It has easy to read on-
screen scoring, and the ten highest scores are recorded
arcade style with the player's initials. After your impending
defeat, you can see if you made the list. The only criticism I
have is very minor and is related to the lack of an explosive
sound when the "beam" hits an outpost or your ammo
dump. It is hard to notice this slight deficiency until you run
out of ammo and have to sit back and watch your outposts
destroyed by the incoming beams - in silence.
Instructions for the game are complete. Spectral
Associates very nicely includes a disk version of the program
on the tape, and instructions on how to load it onto'a disk.
They also give you a number to call if you have problems
with their products. And, there is more; if you should
accidentally erase the tape, for only SI. 50 and the original
tape, they will replace the program. Now, that is what I call
"product support."

GAME
Rise Through the Ranks
With Sub Hunt
By Carl Shell
"Two points abaft the starboard beam, mates! She steams
at forty fathoms! All hands on deck."
Bleeep...bleeep...bleeep...
Sub Hunt is a very easy game to learn, but hard enough to
master so you won't get bored. 1 loaded it into a CoCo at a
local Radio Shack store a few weeks ago, and the kids were
still playing it several hours later when I returned. (Kids?
The store manager was right in there with them!)
Instructions are included in the program and move you
readily into action. You are the captain of a roving
Destroyer, firing depth charges at the enemy submarine fleet
in the murky waters beneath your hull. There are 10 subs to a
fleet and each one is worth 10 points. If you wipe out an
entire fleet, you receive an additional 50 points, and another
fleet of 10 subs appears on the screen.
You have 500 units of time to rack up points, which you
use to climb in rank to Fleet Commander, to Admiral of the
Navy and all the way to Commander in Chief.
While playing Sub Hunt, you only have three keys to use
to accomplish all the action: the "F" key fires the depth
charges, the "G" key moves your Destroyer to the left, and
the "H" key moves it to the right.
I hope you enjoy the sound effects and color I've put into
the program; some of my friends who own other computers
can't believe the CoCo can create the sounds it does in
BASIC.

Supplies.)

Congratulations
you made the right choice when you purchased a
Color Computer. It is a very powerful machine.
However the standard display format does not do the
machine justice The machine is capable of much more than
16 lines of 32 all capital characters. Now you can give your
Color Computer the display it deserves. THE SOLUTION
gives the Color Computer a much better display than it nor-
mally has, and really makes the machine shine. Its features
include:
• provides a screen of 42 characters by 21 lines displayed
• linked directly to basic — program is transparent to the
user
• prints all 96 ASCII characters, lowercase characters
have descenders, has a slashed zero to avoid
confusion when programing
• prints characters on any two-color graphic screen
• graphics and text may be intermixed on the same screen
• special mode with 4 lines of text at the bottom of the
screen (just like some other famous color machines) —
great for working with graphics
• large character mode for small children or the visually
impaired
• character set may be reversed
• written in machine language, program is relocatable
• fast — prints at over 600 characters per second
• works with both cassette and disk
• includes a 20 page manual with demo programs (a lunar
lander program is included)
SOLUTION $14.95
EXTENDER $ 7.95
Still want more than 42 characters per line from your
computer. Then the EXTENDER is for you. This program
when used with THE SOLUTION will give a display of 51

GRAPH LABEL $8.95
Have you ever wanted to place characters on a graphic
screen but couldn't find an easy way to do it. Well then
GRAPH LABEL is for you. This program will enable you to
place characters anywhere on a graphic screen. It will place
any of 96 ASCII characters on the screen or you may create
your own characters. It features a cursor that may be moved
anywhere around the screen with out rubbing out what it
goes over. Superscripts and subscripts may be used since
the cursor may be moved vertically and horizontally in steps
as small as one pixel Lowercase characters have descend-
ers. GRAPH LABEL is written in Basic and is therefore easy
to modify. It may be used by itself or as a subroutine.
SCREEN PRINT PACKAGE $4.95
A package of 2 programs for use with the LP VI I, LPVIII,
DMP100, DMP200, DMP400, DMP500. The programs will
print an image of what is on a graphic screen to the printer.
Both programs work with all the standard PMODEs. The
programs are written in machine language and may be
moved anywhere in memory. The two programs are:
1) SCREEN PRINT — will produce a regular size print. The
image may be located anywhere on a page.
2) DOUBLE SIZE SCREEN PRINT — this program will
produce a full size image that will fill up a sheet of paper. The
finished product is 8 by 6.5 inches in size. Your computer
graphics look really good when they are printed out with this
program.

Manual Review...
Micro-Doc: An Aid
To Organization and Access
Have you ever forgotten which of your disks ortapes held
that favorite program? Did you ever forget exactly when the
warranty ran out on your recently broken printer? Did you
ever forget just where that little bit of crucial information is
found? Well, all of the above, and then some, have happened
to me. That is, until I received Micro-Doc.
"What is Micro-DocV you ask. Micro-Doc is an 8'/ 2 xI I,
29-page, stapled documentation manual which offers easy
documentation to keep all of your information about
hardware and software.
A general introduction to the use of the manual is
followed by some organizational tips, and then three
sections on control of your equipment, data files and
programs. It also contains a summary, a glossary and a very
handy master set of eight forms to aid you in thecontrol and
documentaton of your efforts.
You don't have to be a technical genius to understand
these simple documentation procedures. Micro-Doc comes
with eight easy to use forms, which you can photocopy or
order from Micro-Doc. These sheets help you organize and
easily access all useful information. After a few tries I started
filling out these forms without giving them much thought.
They're that easy to use! Many friends found them easy to
use also. And the instructions are easily followed and
understood.

Software Review...
Clock Gives Reviewer
Hard Time — Vice Versa
Clock is a program that teaches children to read a clock
and teaches the relationship between analog and digital
formats. Apparently not a well thought-out educational
program, Clock starts by asking you if you want just the
analog clock or analog and digital. You are then asked how
many questions you want to answer before receivinga score.
Unfortunately, you are never again allowed to set these
parameters, and are stuck with whatever you start with.
You are shown a clock face with a random time. This is
always in multiples of five minutes. There is no provision for
learning the hours alone or for learning times that aren't
multiples of five like 12:33.
The best feature of this program is its ability to accept
different forms of time telling. Word inputs like "After, Till,
Quarter, and O'clock" can be used. You can say I 10, 01 10,
or 10 After 1 and the program will understand them all.
However, you cannot use "50 Till 2" even though it is
correct. By the same token, "50 After" the hour is considered
wrong even when it is correct.
A big problem is correcting mistakes when keying in an
answer. There is no ability to backspace. Instead, the clear
key in this 16K Extended BASIC program is used to erase
the bottom of the screen where the answer is entered. This is
slow and forces the child to start their answer over again
completely.
A wrong answer is erased and a sound is heard. A correct
answer is erased, the word "GOOD" appears for a moment
and a different sound is heard. My daughter, who is learning
to tell time but cannot read yet, has trouble telling if an
answer is correct or not. In fact, the wrong answer sound is
more interesting.
At the end of a round, a score is printed that indicates how
well a child has done but not where that child is having
trouble. You are then asked if you want to continue. If you
say "yes" you are returned to the game you previously set-up
with no possibility for changing, (switching to digital for
example or changing the length of a round). If you say "no"
to the question of continuing, the entire program is erased.
There is no way for the program to switch from one type
game to the other.
The digital game is just like the analog except that after
entering the analog clock time, you must enter the time
again in a digital form. This merely consists of learning to
put a leading zero in front of single digit hours. For example,
1:10 becomes 01:10.
This program does not work well with children,
particularly those who cannot yet read. It does not have
interesting graphics, rewards, or goals. In short, there is very
little to motivate or to hold the interest of a child. It is not
particularly child friendly. It relies on reading ability or the
close supervision of an adult. The wrong answer response is
at least as much f un as the correct one if not more so, and
sometimes correct answers are counted as wrong.
If you plan to teach your child to tell time yourself, and
are looking for something to supplement your instruction,
then this program may suit you. However, this is not a
program that children will choose to play and it does not
lend itself well to unsupervised play. I feel that this is not a
true educational program and that it fails as a game. I
cannot recommend this program.

RAINBOW
But, What Did
I Get Wrong?
By Steve Blyn
Rainbow Contributing Editor
YouVe got this great educational game going on your
computer. It asks the child some questions in a particular
category and everything appears fine. Let's check — the
questions are coming up randomly. They are not repeating.
You have appropriate reinforcers. Your counters and
scorers are giving a correct final tally or score. What more
could any kid want?
He may very well want to know which questions he got
wrong. Many children cannot remember which questions
they got right or wrong or maybe even which questions were
asked in the first place. Sometimes children (and adults, too)
get so caught up in the excitement of the program that they
forget the questions and answers they have already gone
through.
It's a good idea, often, to let the computer keep track of
the incorrect answers and their accompanying questions.
This is a good opportunity for the adult and child, or the
child alone, to go over the incorrect answers and see where
he went wrong. We don't want the child to merely keep
playing the game until he memorizes all of the answers. We
always hope f or true understanding of the correct answer. A
quick review of the wrong responses before proceeding to
the next set of questions also acts as an extra incentive for
the child to pay close attention to his answers.
Here is a short program to review the symbols for some of
the most important of the chemical elements. The point of
this program is that it demonstrates one easy way to use the
computer to keep track of incorrect responses. If the child
makes any mistakes, they are immediately saved by the
program by the small array set up at lines 270-290. Theyare
printed out at the end of each round by line 330.
This program will work on any of the CoCo models. The
amount of data that you enter can be as large or as small as
your needs and your computer's memory will allow. Be
careful to have the "L" value on line 50 \ ree with the total
number of your DATA pairs. Twenty-five chemical
elements were used in our program merely as an example for
you to key in.
This topic may or may not be suitable foryourchild. Feel
free to enter any data that pertains to what he is currently
studying that he wishes to review. If he is having difficulty,
stay with him and go over the incorrect responses as they
appear on the screen. As he gains confidence, let him work
on his own. When he has mastered the set of questions, enter
new data in the same subject area for additional review.
(Mr. Blvn. who leaches both exceptional and gifted children, holds
two Master 's degrees in the field of education and has won an award
for the design of a computer program to aid handicapped children.
He and his wife, Cheryl, own Computer Island.)

Homing In On
A Guided Missile System
By John W. Fraysse, Jr.
FEATURES
* High resolution four color graphics
with random scenes
* Five levels of difficulty
(three with maneuvering targets)
* Action graphics with joystick control
* Self explaining instructions
* All BASIC programming
Cadet Trainer is an attempt (I hope a successful one) to
simulate the two phases of a command guided weapon
system. That is, lock-on (or target discrimination) and
terminal homing. In this game, your weapon is a "photon
torpedo." Playing Cadet Trainer may develop one's
peripheral vision and eye-hand coordination.
The graphics are programmed to simulate the apparent
growth of the target as the photon torpedo closes. Note that
the player is guiding the torpedo f rom his fighter craft. The
player is not the torpedo but is seeing the target through the
"eyes" of the torpedo itself.
PROGRAMMING TECHNIQUES
Cadet Trainer \s written in BASIC. Theonly so-called tricks
are a BREA K key disable and the familiarspeed up POKE
65495,0 to achieve the speed I believe necessary to give good
response to joystick inputs.
PROGRAM FUNCTION
Cadet Trainer's initial display identifies itself and its
author while playing the Air Force theme song. Optional
instructions follow if needed. One must then select the
difficulty level (1-5) which will be discussed later. The
program will then draw the various perspectives of the target
and display a flashing cross on the largest perspective pin
pointing your "aim point "on the target. Press the fire button
to erase the screen and draw the sector of space in which the
smallest image of the target will appear at random for only
an extremely short period of time.
You are now in the lock-on phase of your mission. You
must position your small orange cross-hair (with the right
joystick) to within eight pixels of the target's last position
and press the fire button to begin the homing phase. If you
achieve this, your booster motor will fire, propelling your
torpedo into space where the approaching target will appear
first small then progressively larger. Remember you must
now position your cross-hair on the correct part of the
target your aim point. Af ter the largest image appears, you
have approximately one second before you reach the target.
This time gets reduced with the higher difficulty levels. Af ter
you have reached the target your simulated warhead
explodes and your miss distance for that particular mission
and aim point is displayed briefly. The program then
displays the aim point for the next mission. A mission
consists of one lock-on phase and one homing phase. Five
missions complete one play cycle where your score is
totalled. You may then replay and/or change the difficulty
level or BREAK to exit. Your score for the entire play cycle
is the sum of all your lock-on times plus your five "miss
distances." Obviously, the lower the score the better. It
should also be noted that the lock-on timer does not start
until the first target image appears.
DIFFICULTY LEVELS
1) Targets appear every time a random number between
1-20 equals 2. Targets do not maneuver and final
homing time is 1.8 seconds.
2) Targets appear every.time a random number between
1-10 equals 2. Targets do not maneuver and final
homing time is 1.6 seconds.
3) Targets appear every time a random number between
1-7 equals 2. Targets maneuver plus/ minus SO pixels in a
predictable fashion. Final homing time is 1.4 seconds.
4) Targets appear every time a random number between
1-5 equals 2. Targets maneuver plus/minus 100 pixels in
a predictable fashion. Final homing time is 1.2 seconds.
5) Targets appear every time a random number between
1-4 equals 2 (FAST!). Targets maneuver as much as
plus/minus 100 pixels in a random fashion. Final
homing time is 1.0 seconds.
HINTS
You may hold yourbuttonduringthelock-on phasewhile
trying to find the target. During homing the button is not
used.
Try to keep the cross-hair slightly off the aim point to
keep it from being lost in the target or background as your
torpedo closes. Remember the target image grows. Try to
anticipate your aim point's next position. Make your move
to the aim point after the final (largest) image has appeared.

THE ORIGINAL
Simply stated, Telewriter is the most powerful
word processor you can buy for the TRS-80
Color Computer. The original Telewriter has
received rave reviews in every major Color
Computer and TRS-80 magazine, as well as
enthusiastic praise from thousands of satisfied
owners. And rightly so.
The standard Color Computer display of 32
characters by 16 lines without lower case is
simply inadequate for serious word processing.
The checkerboard letters and tiny lines give you
no feel for how your writing looks or reads.
Telewriter gives the Color Computer a 51
column by 24 line screen display with true
lower case characters. So a Telewriter screen
looks like a printed page, with a good chunk of
text on screen at one time. In fact, more on
screen text than you'd get with Apple 11, Atari,
TI, Vic or TRS-80 Model III.
On top of that, the sophisticated Telewriter
full-screen editor is so simple to use, it makes
writing fun. With single-letter mnemonic
commands, and menu-driven I/O and
formatting, Telewriter surpasses all others for
user friendliness and pure power.
Telewriter's chain printing feature means that
the size of your text is never limited by the
amount of memory you have, and Telewriter's
advanced cassette handler gives you a powerful
word processor without the major additional
cost of a disk.
...one of the best programs for the Color
Computer I have seen. .
TELEWRITER-64
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
— 16K, 32K, or 64K, with or without Extended
Basic, with disk or cassette or both. It
automatically configures itself to take optimum
advantage of all available memory. That means
that when you upgrade your memory, the
Telewriter-64 text buffer grows accordingly. In
a 64K cassette based system, for example, you
get about 40K of memory to store text. So you
don't need disk or FLEX to put all your 64K
to work immediately.
64 COLUMNS (AND 85!)
Besides the original 51 column screen,
Telewriter-64 now gives you 2 additional high-
density displays: 64 x 24 and 85 X 24!! Both
high density modes provide all the standard
Telewriter editing capabilities, and you can
switch instantly to any of the 3 formats with a
single control key command.
The 51 x 24 display is clear and crisp on the
screen. The two high density modes are more
crowded and less easily readable, but they are
perfect for showing you the exact layout of
your printed page, all on the screen at one
time. Compare this with cumbersome
"windows" that show you only fragments at a
time and don't even allow editing.
RIGHT JUSTIFICATION &
HYPHENATION
One outstanding advantage of the full-width
screen display is that you can now set the
screen width to match the width of your
printed page, so that "what you see is what
you get." This, makes exact alignment of
columns possible and it makes hyphenation
simple.
Since short lines are the reason for the large
spaces often found in standard right justified
text, and since hyphenation is the most
effective way to eliminate short lines,
Telewriter-64 can now promise you some of the
best looking right justification you can get on
the Color Computer.
FEATURES & SPECIFICATIONS:
Printing and formatting: Drives any printer
(LPVII/VIII, DMP-I00/200, Epson, Okidala,
Centronics, NEC, C. Itoh, Smith-Corona,
Terminet, etc).
Embedded control codes give full dynamic access to
intelligent printer features like: underlining,
subscript, superscript, variable font and type size, dot-
graphics, etc.
Dynamic (embedded) format controls for: top,
bottom, and left margins; line length, lines per page,
line spacing, new page, change page numbering,
conditional new page, enable/disable justification.
Menu-driven control of these parameters, as well as:
pause at page bottom, page numbering, baud rate (so
you can run your printer at top speed), and Epson
font. "Typewriter" feature sends typed lines directly
to your printer, and Direct mode sends control codes
right from the keyboard. Special Epson driver
simplifies use with MX-80.
Supports single and multi-line headers and automatic
centering. Print or save all or any section of the text
buffer. Chain print any number of files from cassette
or disk.
File and I/O Features: ASCII format files —
create and edit BASIC, Assembly, Pascal, and C
programs, Smart Terminal files (for uploading or
downloading), even text files from other word
processors. Compatible with spelling checkers (like
Spell 'n Fix).
Cassette verify command for sure saves. Cassette auto-
retry means you type a load command only once no
matter where you are in the tape.
Read in, save, partial save, and append files with disk
and/or cassette. For disk: print directory with free
space to screen or printer, kill and rename files, set
default drive. Easily customized to the number of
drives in the system.
Editing features: Fast, full-screen editor with
wordwrap, block copy, block move, block delete, line
delete, global search and replace (or delete), wild card
search, fast auto-repeat cursor, fast scrolling, cursor
up, down, right, left, begin line, end line, top of text,
bottom of text; page forward, page backward, align
text, tabs, choice of buff or green background,
complete error protection, line counter, word counter,
space left, current file name, default drive in effect,
set line length on screen.
Insert or delete text anywhere on the screen without
changing "modes." This fast "free-form" editor
provides maximum ease of use. Everything you do
appears immediately on the screen in front of you.
Commands require only a single key or a single key
plus CLEAR.
...truly a state of the art word processor.,
outstanding in every respect.

Dumb Terminal Routine
Is Pretty Smart Program
By Dan Downard
This month we will be discussing how the CoCo outputs a
character on the screen. For the sake of using the existing
BASIC subroutine for Machine Language programs, we
will see how it operates. We will then develop our own
character output routine for use with other computers. This
routine is called DM BTRM, a shortened name for dumb
terminal. What is a dumb terminal? A dumb terminal is
simply a keyboard and display device that sends and receives
(display) characters over a serial/ RS-232 interface.
ROM Character Output Routine
If you were to disassemble the BASIC ROM from SA30A
to $A35D and $A92D to $A936, you would get a listing
similar to Listing I. Comments have been added to explain
the operation. As you can see, this routine is called with the
character to be output in the A register. All registers are
saved. This routine is called using direct addressing at
$A30A or by indirect addressing at $A002, assuming $6F is
set to 0. As you can see, any character less than $20 is
ignored with two exceptions, SOD and $08, the ASCII
symbols for carriage return and backspace, respectively.
Three routines contained in this listing may be of some use:
$A30A output char, in a reg. to screen
$A34B scroll screen
$A92D
Any call to $A34B must be preceded with a PSHS A,B,X
instruction to keep the stack organized. By this time, you
should have figured out that the text screen starts at $400
and ends at $5FF. The position of the cursor is stored at
location $88 and can be called the screen pointer of
SCNPTR. This routine is fine f or the majority of Machine
Language programs and very convenient to use.
DMBTRM
While trying to use my Color Computer as a dumb
terminal for another computer, the need arose to have full
cursor control of the screen. The particular system I was
dealing with used the following ASCII codes:
$0A (LF) line feed
$0D (CR) carriage return
$08 (BS) backspace
$07 (BEL) bell
$1A (SUB) clear screen
$0C (FF) cursor forward
$0B (VT) cursor up
The program in Listing 2 is the result of this need. A
similar program written for a 6801 processor in Motorola
application note AN-798 was used as a guideline for this
terminal. More elaborate programs are available on the
marketplace that will do the same and much more but there
is some satisfaction in writing and debugging your own
program.
Description Of DMBTRM
Lines 140-190 ROM locations
Lines 190-450 Main timing loop/cursor blinking
Lines 460-740 Serial output
Lines 750-770 Scroll decision
Lines 780-1 130 Serial input
Lines 1 140-2140 Display char on screen
DMBTRM uses a non-destructive cursor, that is, the
cursor does not erase the character as it moves. It operates at
300 baud and has proved to provide reliable operation with
another 68XX computer using the Color Computer as a
terminal. The listing is commented so you can pick out any
of the major subroutines for use on your own customized
terminal.
How To Input Your System
I realize that many readers are not familiar with machine
code programming, so a short explanation of Listing 2 is in
order. This program was written using the Radio Shack
EDTASM+ ROM Pac. The listing can be explained for a
typical line as follows:
3000 8E 0600 00190
CLEAR LINE
Memory address: 3000
Machine code: 8E 0600
Line number: 00190
Symbol: START
START LDX #$600
160 the RAINBOW March, 1983
Nemonic operator: LDX
Operand: #$600
Comments: CLEAR LINE
These different locations are called fields and fully
explained in the EDTASM+ manual. The reason I am
describing the fields is to point out the different ways of
inputting a Machine Language program.
Method #1 — Put Machine Code In Memory
Using a Machine Language monitor such as C-BUG,
SIGMON, HUMBUG, Z-BUG, etc., you would input this
program by using the MEMORY EX A M 1 N E command.
Start at memory location $3000 and input column 2 until
you reach memory location $3196.
Method #2— Use An Assembler
Using an Editor/ Assembler such as EDTASM+ or SDS-
80C, input columns 3 through 6 as a file. For the SDS-80C,
line numbers are qptional so omit column 3. Column 7 is
optional on all assemblers. After inputting the text file use
the proper command to assemble the file and the assembler
will put the program in memory for you.
Method #3— Poke Using BASIC
As in method #1, start at memory location $3000 and
using POKE or DATA statements transfer the machine
code into memory.
After you have put the code in to memory be sure to save a
copy to tape before running. It's a lot easier to find a mistake
than to retype the entire code or file. The entry address is
$3000 or £ATC&H3000 and ENTER.
Conclusion
As I mentioned before, there are many commercial
software programs that perform this task (and probably do
a better job). Refinements consist of buffers, variable baud
rates and character formats, saveand load buffers from tape
or disk. They are very reasonable and well worth the
investment. At the same time, much can be learned by doing
it yourself.

HERE ARE SOME GOOD REASONS FOR JOINING
FREE PROGRAMS. Good programs written by our members are contained in the library,
in the newsletter, and on the new member tape.
NEWSLETTER. A "magazine" sized newsletter (last issue 80 pages), with programs, tips
data, reviews, articles and much more.
NEWSLETTER Tape A tape of all the programs appearing in the newsletter is available from
the library for $2.00 (to members)
The club maintains a library of programs, books and Radio Shack ROM-
packs. The programs are member written and are yours to keep, there is
a small fee to cover postage and tape ($2.). The books and ROMpacks
may be c' ocked out for 3 weeks at a time, (extencions possible)
get large discounts on many software and hardware items for CoCo
from some of the MAJOR companies. Also discounts on subscriptions
to the RAINBOW, CCN and Chromasette magazines.
ADVERTISE FREE Members may place ads of up to % page per issue in the newsletter
FREE. (The ad must be computer related)
Don't wait weeks for the parts to come in from Radio Shack! Just
check them out of the Clubs Parts library and return when yours arrive.
You receive a "New member" package containing many useful items.
This is the worlds largest Color Computer Club. With members in almost
every field of expertise. So if you have a problem with the Color

Son Of
Graphic Traffic
One of our favorite program quickies is the five-liner sent
in to us by John Dana of Hamden, Connecticut. It appeared
in our December 1982, issue under the title of Graphic
Traffic. Now John has created Graphic Traffic II: Color
Craziness. It's a great simulation of a CoCo that's blown its
cool.
John added color by adding just two lines to his
December version — lines 8 and 15 — and by changing line 5
from CLEAR 100 to CLEAR 600. If you missed the earlier
version, just key in the lines below and RUN it. then hit
ENTER twice and then a few keys, for instance, your name,
for the old verson. Hit the space barseveral timesand watch
what happens.
For the color madness, RUN the program again, but this
time enter a number (96 or above for full color — color only),
and then hit ENTER. Now, each key on the keyboard,
including the shift/ zero mode, becomes a color key.
What happens is that the value you input is added to the
ASCII value of the key you hit, and the character on the
screen has the new ASCII number (the sum of the two
values).
Caref ul: if the sum is greater than 255. you'll get an error
code.
The effects are seemingly endless and, when you find a
combination you like, you can preserve it in string or data
statements — if you can remember what you did. At
Rainbow, we find it's fun just in itself, but you could add it as
a subroutine in a game program you're working on, too.
If things get a bit dizzying, particularly in the December
version, add in a line somewhere, say line 35. that reads:35
FOR X=l TO 8: NEXT X (a FOR-NEXT loop lor time
delay). Increase "8" to a larger number for a longer pause.
Here's the listing:

LISTEN UP
So. you've got an IO error on the first save of your favorite
program, and you can't remember how far in the second
save is. What to do? Just keep typing CLOAD until the
second save finally comes up? Steve Lipps of Circle City
Software has a better idea. If you put a little space between
your saves, as many of us do, then you can listen for the
second save. Says Steve, "Just use AUDIO ON and
MOTOR ON and listen for the silent space. Then you can
use MOTOR OFF. Even faster than MOTOR OFFis to hit
any key and then ENTER, creating a syntax error which will
stop the recorder." Then CLOAD the second save.

From Way Up And Way Over
Here's J/K Draw
Program by Aaron Franksen
As you might expect, when we get mail from Cleveland,
we don't rush to the road atlas to see if it's the largest city in
Ohio. On the other hand, when we get a cute little program
sent to us from Revelstoke, British Columbia, it's reach for
the World Book time.
Aaron Fransen lives in this westernmost province of
Canada and we like to think he uses his CoCo in the
seclusion of a small cabin in the Monashee Mountains near
Glacier National Park. There's probably a deer grazing in
the meadowjust outside his window, and maybe he uses his
CoCo to plot the migratory patterns of wild geese. He's
probably snowed in for the winter and will have his next
issue of the Rainbow delivered by dogsled.
Yeah, that's what we like to think. Aaron, if you're the
manager of the local McDonald's and drive a Dodge, just
don't tell us, okay?
More than anything else, what does set Aaron apart from
most of our contributors is that he's developed a program in
non-Extended BASIC. We agree with him that more
programs are needed that do not require ECB.
J/K Draw uses both the right joystick and the arrow keys
to draw block graphics pictures on the low resolution screen.
Once you've completed a masterpiece, you can save it to
tape, too.
Writes Aaron, "I have found that young children enjoy
this program a lot when they get the hang of it." Some of us
who aren't children, but who treasure and cling to those
childlike qualities we still manage to possess, like J j K Draw,
too. The colors are brilliant and clean. Doodling with J/K
Draw is sort of like playing around with Magic Markers,
those felt pens with the wide tips. We tried our hand at
drawing a little cabin in the woods.

Remote Interest
Quickens with Remoterm
What do you do on your lunch hour? Well, depending on
how much time you have, or maybe depending on whether
you have a terminal at your disposal, you can talk to your
CoCo at home. Star-Kits has come up with another gem ofa
program in Remoterm. This program allows you to control
and run your TRS-80C from a remote terminal or a modem.
Remoterm comes on cassette or disk. More than adequate
information on its proper operation is given in the 10-page
manual. To summarize, after loading the program at the
memory location of your choice, it's in position independent
code — the TRS-80C is controlled by both the keyboard and
the RS-232 port. At the same time all output goes to the
screen and the RS-232 port. The program is written in
machine code and will run in 4K, although ! 6 K is
recommended. Operation is at 300 baud; higher baud rates
are mentioned but not recommended.
Well, I guess you're thinking along the same lines as I was:
this is great, but there are limitations. As the manual
explains, during remote operation there is no way to hit the
reset key for a hung-up program. A control-C from the
remote terminal will simulate the break key. Maybe the
modem you are using has this facility but be careful. The
other problem was discovered quite by accident. 1 was using
a terminal in the same room and tried to load a machine
language program from tape. It just so happened that the
program was at the same address as Remoterm and
completely wiped it out, hanging-up the computer. My
mistake, but something to remember.
There are several other uses for this program besides
remote operation of the computer. Those of you who prefer
a professional keyboard while using a word processor will
find Remoterm the answer. For the same reasons, you may
want a screen display different than 32 x 16, even though
some other software is available for this purpose. Obviously,
no graphic screens are available on the remote terminal and
care must be exercised with program selection as various
graphic commands will not work through a serial interface.
In summary, I recommend Remoterm to anyone
interested in remote operation of the CoCo, for whatever
purpose. The program does exactly what it is supposed to
do. The documentation is excellent, complete with a
commented listing of the source code. I would recommend
that if remote operation is contemplated, a disk system is
almost a necessity due to the mechanics of tape files. I found
the program both interesting and valuable.

Preread Series is Good
Head Start Program
If you have a young child you would like to see receive a
he"ad start in reading, Preread by Prickly-Pear Software is
an excellent tool with which to begin. Three programs are
contained in the Preread package. They can teach the young
child from three years up important letter recognition.
Preread 1 presents the names of the letters of the alphabet
auditorially (by voice on tape) and asks the learner to press
the letter on the keyboard which corresponds with the letter
name. The voice is pleasant and nonthreatening.
Preread 2 presents the sounds of the letters of the alphabet
in the context of words and asks the learner to press the key
which corresponds to the sound which that letter makes.
Vowel sounds are short and those letters (such as c and g)
which have two sounds are prompted with the "hard"
sounds. The letter"X" is presented as the "K" sound at the
end of the word "box." The Q sound is presented as the first
of the two letters at the beginning of the word "quiet." The
sounds are presented out of sequence.
Preread J flashes random letters visually at the rate of
one-fourth, one-half, or ofie full second. This rate is
preselected. The learner is then to respond by pressing the
correct key which corresponds to the letter he or she has just
viewed on the screen. You select the number of letters you
want the learner to view.
If the learner presses the correct key in any program, a
Happy Face appears on the screen. Next the correct letter is
graphically presented in both upper and lower case.
In Preread I and 2, an incorrect key press brings a Sad
Face to the screen. Next, the correct letter is graphically
presented on the screen. This flashes three times while the
sound which accompanies a correct response is repeated.
Another sound is used when an incorrect response is given;
this allows the parent or teacher to auditorially monitor the
learner's progress.
In Preread 3, an incorrect response is followed by the
same Sad Face, but the letter is repeated until the learner
makes the correct response.
The Preread package is an excellent group of programs,
which a child of three years up to age six would benefit f rom.
It is well documented, with the exception of loading
procedures, which should be separated from the text. My
son, a kindergartner, thoroughly enjoyed all three
programs. They keep the child's interest and are viewed as a
game, not a test, although a percentage score is given at the
end of each program.
All programs give the learner unlimited time to find the
letter asked for, but the original question is not repeated,
thus encouraging the child to develop good listening and
attention spans.
One addtional comment — several of the letter shapes, V
and W especially, were confusing to the young learner.

Inspector Clueseau Is
Not Elementary, Sherlock
Inspector Clueseau is a mystery game that would tax the
deductive reasoning power of Sherlock Holmes. Mr.
Goodbody has been murdered and you must solve the
mystery. You must discover who committed the murder, the
weapon used and in what room the crime occurred. Solving
the mystery will not be easy because there are six suspects,
eight possible weapons and nine rooms in the mansion.
You will have seventy-five game turns to solve the
mystery. Each game turn will randomly place you in a room
of the mansion with one randomly selected suspect. A hi-res
graphic display will show your location in the mansion. You
will have a choice of questioning the suspect, searching f or a
secret passage, or making an accusation.
Most of the information used to solve the mystery will be
derived from questioning the six suspects. You can't trust all
of the suspects! Miss Violetmight lieorchangehermind and
Mr. Denton lies all the time.
Each game will have one randomly selected room with a
secret passage. Upon entering a new room, search for the
secret passage. If you are in the correct room, a secret door
will open allowing you to entera hidden chamber. You will
be given a four letter code to solve. If you successfully solve
the code within the allotted ten tries you will receive a CLUE
or the message "Clues are getting scarce — try again." You
will be returned to the game board after ten unsuccessful
tries. One game turn is used each time you search for the
secret passage.
You only have one chance to make a correct accusation. If
you are wrong you will be given the correct suspect, weapon
and room.
The instructions are clearly written and accurate.
Inspector Clueseau is easy to play, but not necessarily easy
to win. Hi-res graphics are used throughout most of the
game. I especially liked the use of the hi-res alphanumerics.
My wife enjoyed thesecret door graphic and sound routines.
Inspector Clueseau uses the Auto Run program
(copyright Sugar Software). There are some POKE65495.0
and POKE 65494,0 commands used in the program to speed
up and slow down computer operation. The speed up
command can't be handled by some CoCo's. The Auto Run
program prohibits the editing of the POKE 65495,0
statements. A version of Inspector Clueseau could be sold
without the speed up POKE statements.
Anyone who enjoysadventureormysterygameswill have
lots of fun playing Inspector Clueseau. This game will fine
tune your deductive reasoning skills.

COMMENT
Monitor
What is It? Who Needs It?
By Sue Searby
A "monitor" is not always just the kid in charge of
checking the balls out and in for recess! In "computerese"
the word "monitor" has taken several new meanings.
First, monitor can mean a video screen that hooks to a
computer much like a TV on which the computer displays its
information. This use of "monitor" could be replaced by the
term, "CRT," or screen. The other use of "monitor" in
computer jargon is less concrete and we will concentrate on
it.
A monitor is a program, software, that communicates
directly between you (the user) and the computer (CPU and
memory). Like the elementary school's ball monitor, it has
the responsibility of "go-between."
When the user types in one of the monitor's commands,
the monitor will go to the computer's CPU or memory, fetch
the information, and display it on the screen for the user to
see. The monitor also has commands to tell the CPU to do
something to change values in the memory.
In summary, the monitor is a "low level" communicator
program between the user and the computer. Below are
some example monitor commands and functions.
A - Examine and change A register
F - Find a byte string
G - Go to user's program
I - Initialize memory
J - Jump (subroutine) to address
K - Set breakpoint
M - Memory examine and change
L - Binary load from cassette
S - Binary save to cassette
T - Text input to memory
V - Set breakpoint and begin execution
W - Warm start into BASIC
Z - Display formatted memory dump
Who needs or uses a monitor program'.' A programmer
who does machine language or assembly language
programming uses the monitor to test his programs and
learn about the internal operations of the CPU chip and the
memory. Most users or even BASIC programmers do not
have a need for a monitor program. Some companies who
sell monitor programs use the rule, "If you don't know what
a monitor is. you do not need one." Of course, even though
you know what a monitor is, you need not assume you need
one. And conversely, just because you don't need one does
not imply you do not WANT one! A monitor is a very
powerful and useful tool for those who are serious about
learning the "nitty gritty" about computers and assembly
language programming. And isn't this what it is all about —
learning about this new technology? So do not be afraid to
venture out. make mistakes, and learn new things either with
a monitor program or with some other new concept you
encounter.
(Ms. Searby is a principle in Computerware, which
publishes a number of monitor programs f or the Color
Computer.)

TURN OF THE SCREW
Green On Black Video:
'Eye Friendly' Conversion
By Tony DiStefano
It's two o'clock in the morning and you are typing away
on your TRS-80 Color Computer. Your eyes are burning
because you've been staring at that bright green screen
trying to create your "Do everything program'Tor hours. So
you turn down the color, contrast and brightness of the
display but that doesn't help too much. It's still a big square
of light. Well. ..what can you do? Follow these simple
instructions and when you are finished you will have a
reversed screen like mine.
Though these instructions are simple, only those with
soldering experience should attempt this project. You will
need a Phillips screwdriver, a grounded soldering iron,
solder, an IC extractor, two pieces of thin wire, flux cleaner,
and a little patience. And, if you haven't received the
warning before, opening your computer may void your
warranty.
Before you start tearing into your computer, a bit of
background on the VDG (Video Display Generator) is in
order. The VDG is a large scale integrated circuit (LSI) chip
that takes care of all the video you see on the screen, be it
Alphanumeric or full graphic. The VDG continually scans
memory (Via the SAM) and displays what it sees. In the
Alphanumeric mode it converts the ASCII code of a byte of
memory into a graphic block that looks like the letter it
represents. Normally an upper case letter or number is black
with a green background. Lower case letters are the
opposite, green with a black background. What my circuit
modification does is reverse the order so that upper case
letters are green with black background and lower case
letters are black with green background. This does not
change anything in memory nor does it interfere with
BASIC. It also does not change any graphic modes or color.
Everything stays the same except the letters, numbers and
symbols. The diagrams in this article pertain to most
versions of the computer. Version 1.1, 1.0, 4K, 16K, 32K,
64K, BASIC, Extended BASIC, and even Disk BASICare
OK. The only version of which I cannot say "it works" is the
newest version, the one with the power supply in the bottom
left hand corner. It should be the version "F" but it is not
written anywhere on the board.
Before you start into this, make sure that you havea large
clean work space. Make sure the computer is not plugged in.
FIG-l
Put the computer upside down on a soft surface. Unscrew
the seven screws that hold the cover on. If you haven't
opened it bef ore, the seventh screw is under the black sticker
that warns you not to open this thing. Turn the unit over
again (top side up) and pick up all the screws that fall out.
Put them aside in a safe place. Remove the top cover and put
that away, too. Lean forward slightly and gently pull up on
the keyboard. Unplug the connector that ties the keyboard
to the main board. Put the keyboard aside. Now cut the two
tie wraps that hold the RF shield in place. That's the big
square piece of metal with holes in it. Remove the RF shield
and put it with the other parts. You are now ready for part
two.
Before you start part two, let me tell you that the board is
very sensitive to static electricity. Try to avoid dry areas and
avoid touching thecontacts on the board whenever possible.
OK, let's get going. Locate and pull out the 74LS02 IC
marked U29 on the PC board. Carefully bend pins 1 , 2and 3
so they stand straight up in the air upside down. The dot
denotes pin # 1 . If you are facing the computer it is the top
left hand corner. See Figure 1 . Now solder one end of a four-
inch piece of wire to pin # 1 of the IC. The best wire to use is a
#28 or #30 Wire Wrap wire. Solder another piece of six-inch
wire to pins 2 and 3. Yes, both pins together. Now put the IC
back in the socket. Make sure it is in the right orientation.
The dot should be in the upper left hand corner. Also make
sure that the wires and the pins do not touch the side of the
RF shield. Now carefully remove the MC6847 IC marked
U7 on the PC board. Bend pin #32 outwards just enough so
that when you replace it, it does not go into the socket.
Replace the MC6847. Again, make sure of the orientation.
The dot should be in the upper right hand corner. Take the
other end of wire that connects to pin I of the 74LS02 and
solder it to pin 32 of the MC6847. Take the otherend of wire
that connects to pins 2 and 3 of the 74LS02and solder that to

pin 2 on the MC6847. Be careful not to solder the pin to the
socket. You won't be able to get the IC out if you do. Check
the wiring and make sure that there are no shorts. Your
wiring should look like the wiring in Figure 2. Now turn the
power on. You should see the normal SIGN ON and

Again, make sure that there are no wires hanging out, and
that there are no small pieces of wire or solder left in the
closed area. Replace the keyboard and connector and put
the lid back on. One thing to note when you are putting the
bottom screws on is that there are two short screws. They go
under the keyboard. If you put the long ones there you'll
pierce a hole in the top cover. Do not overtighten them.
After the computer is all back together again check all the
functions just to make sure that all is running properly.
The whole operation should go off without a hitch, but if
you do have problems retrace all of the above steps. The
circuit does work, and if yours doesn't work you may have
made a mistake somewhere. Some of you might want to add
a switch to be able to change back and forth between normal
and reversed screen. To do so, follow the wiring diagram in
Figure 3. Make the wires long enough to be able to mount
the switch on the outside cover or somewhere accessible
when the cover is on. Warning! Wires that run outside of the
RF shield can cause interference with your TV. Using a
shielded wire will help. Ground the switch cover with a
separate wire. This should take care of most of the RF
problems.
Good luck.

Rapid Logger
Handles Contest Heat'
By B. B. Witham, Jr.
W4CNZ
The program listed here is sort of a natural follow up to
my l.ogsheet ( December '82 Rainbow) and Duper (January
'83 Rainbow). It is the fourth in my series of 1 '/amplication
programs and contains many features of the previous
programs, plus some new ones. There seemed to be a need
for a specialized contest log that could go beyond a plain log
and a separate Duper program in providing rapid logging
input during the heat of a contest. Most contests have a set
of rules that specify purpose, hours ol operation, point
scoring and the like. Getting all the various rules and scoring
details into one program was my aim. The problem is that
the differing requirements made it impossible to match all
the contest rules. However, most of the factors can be
included and the printout can be user modified, if needed.
Even the scoring scheme can be changed to lit a particular
contest. At least this program w ill provide a basis for ham
operators to use their imagination in modifications.
Prior to running the program, I execute an M I. clock
routine to use as a time input to the log. Any clock routine
can be used as long as it places the current time in the upper
right corner, where the screen addresses are PEEKecl and
relocated into the correct place of the log format. I did not
include it as part ol the program, because theones I haveare
adequately available (Chromaselte "CoCo-Cooeoo",
August '82) and (CCNews "Time Clock." December '82),
and they are copyrighted. Choose your own. Anyway, the
time of contact and then the outgoing contact number are
automatically entered into the log format and memory.
Alter the timer is started, the parameters of the contest are
entered into memory to use in scoring and printout. A "0" is
entered lor "not applicable" or "no score" items.
During entry of the scoring scheme, some contest rules
specify only adding the total number ol scoring points, while
others multiply the number of contacts by the scoring
points. For instance: prefixes — if the score is just I point lor
each prefix worked, then enter "prefix pts:"-l and a T under
( + ) and 'enter' under (X). On the other hand, if the rules state
to multiply the (JSO's by two lor each different pre fie. then
enter "prefix pts:"-2. under ( + ) "enter'and under (X) -' I '. The
scoring computations in lines 180-230 are adjusted
accordingly.
The log format guides the operator through each QSO.
keeping a record of those items needed lor score and record.
In the log form an "NA" is entered if the item is not a
requirement ot the particular contest. Upon entry of the call
sign and frequency, the dupe routine checks to see if the
station has been worked on that frequency before. If not. the
program returns to the logging format for continued entry
of data. If it is a dupe, this is reported and the program
returns to input another call. On completion of each contact
the record is dumped to disk. This is somewhat a waste of
disk space, but it is quick, and avoids the problem of a full
buller and loss ol data with variable length records. Since
the program is written lor two disk drives. I use drive tt\ for
my data storage. If a single drive is used, then change lines 80
and 98 by dropping the ': I 'alter the extension. If a cassette
system is used, then make the following changes
Line 80 change tt I to tt- 1, delete LOG: I
Lines 82. 84. and 86 change tt\ to tt-\
Line 98 change tt I to tt- 1, delete LOG: I
Lines 98. 100. 102. 104. 106. and 108 change ttl to tt~\
After the contest completion, the whole file can be
reloaded and reviewed and or printed out. The scoring
factors and score are computed and are part of the print out.
Of course, change the call sign in line 144. Also, if your
computer will not take the speed-up POKE, delete these
from lines 66. 70, 72. 174. and 214.

** PEEKS AND POKES **
Two of the most fascinating commands
in the 3a sic language are PEEK and POKE.
While we can't claim to be experts on the
subject, we can offer a few ways to use
PEEK and POKE to help you get more out of
your CoCo.
The most famous POKE is probably the
high-speed, or vitamin-E ooke. There are
actually two of these — the well known
POKE 65495,0, and the ]ess common POKE
65497,0, which is actuc'illy faster. You
lose control of the screen r but it c n be
used for searches, sorts, or calculations
where screen control is not necessary.
It should be noted that these speedup
techniques do not work on all computers.
Trie following progr m will let you know if
the pokes work on your computer, nd will
give you an idea of the speed difference
of each.

The Radio Shack joysticks
are ok but there are a lot of
better ones on the mar-

but even their joystick
leaves a lot to be desired.
Many companies have
started making Premium

WICO is the best of the
Premium joysticks The
Wico stick will not plug in
to the COCO though, you
need an adapter. The
adapter will work with any
Atari type loystick You
could buy one Wico for
yourself and use an old
Atari stick for your friends
(you'll never losei Or
splurge and get two Wicos.

PRINT #-2,
of Spectrum Projects and taking issue
with a letter we printed in which the
writer expressed dissatisfaction with the
Spectrum Stick joystick.
Mr. Cassidy's letter reads in part:
"Over the past twelve months 1 have
had several dealings with Spectrum
Projects and purchased many products,
including the Spectrum Stick. 1 agree
with your reviewer that it is an excellent
joystick. Indeed, 1 have been satisfied
with everything 1 have purchased from
Spectrum Projects.
"However, the satisfaction with a
specific product is not the point at hand.
1 was particularly concerned with the
inference that 'Spectrum gets away with
taking people.' In my many contacts
with Spectrum Projects, 1 have always
found Mr. (Bob) Rosen and his staff
extremely friendly, courteous and,
more importantly, fair and honest.
"It concerns me that (the writerof the
original letter) gets away with a slur on a
completely reputable company... I find
it completely irresponsible on your part
to publish such a potentially damaging
letter without having fully researched
the matter."
We are glad that this issue came up
and that we have an opportunity to
explain how we at the Rainbow deal
with letters of complaint and, finally,
how they find their way into our letters
column. 1 want to explain it here,
primarily because 1 think it will help
everyone to know about the procedures
we are supposed to follow.
But, let me emphasize, we are not a
consumer watch-dog agency. In that
regard, we certainly will try to help you
solve any problem you may have — with
an advertiser or, f or that matter, with a
non-advertiser. The only place we draw
the line is with other publications. And
there is a simple reason for that. To
ultimately carry a letter about another
publication failing to honor a
subscription, being consistantly late or
the like only sounds — at least to us —
like the Rainbow trying to knock a
competitor, no matter how "friendly"
that competitor might be. So, generally
speaking, you won't see much here
about any other publication.
Aside from that, we have a procedure
that we are supposed to follow in every
case. Letters of complaint are
forwarded to the firm in question, as a
matter of information for the firm. We
work on the assumption that you would
like to have the problem resolved and,
frankly, many times a letter to a third
party is enough to resolve the issue.
Firms are asked to let us know what has
been done, or whether they would like
to make a response if we print the letter
in question.

188 the RAINBOW March, 1983
I am beginning to get really excited about
RAlNBOWfest— which is, after all, "CoCo's Very First
Usually, most of the problems our readers experience are
resolved in this way: Oftentimes it is only a lack of
understanding on the part of one party or another,
sometimes a problem with either the Postal Service or
another carrier such as UPS.
We have two concerns in issues such as this. The first is for
our readers, in terms of assisting them in any way possible.
Since the Rainbow has been founded, I suspect several
hundred disputes have been easily resolved when the two
parties talked it out, either by mail or telephone.
The second concern is for the firm in question. We are
fully aware of the "power of the press"and we intentionally
set up procedures so that the firm has an opportunity to
respond. To do otherwise would allow anyone with a "bone
to pick" against someone else to simply fire off a letter and
do considerable damage to someone's reputation.
In the case of the letter about which Mr. Cassidy wrote,
this system did break down and the letter was printed before
we offered Spectrum Projects an opportunity to respond. It
was a serious error on our part and for that error, we wish to
apologize to Mr. Bob Rosen and to Spectrum Projects. As a
footnote, we understand the question has been fully
resolved.
We do not wish to set ourselves up as an arbiter of
disputes. That isn't our job. At the same time, we want to
help settle any disputes which may arise in any way we can.
And. we will publish "Brickbats" when the situation
warrants hopefully, at least, with a response from the
other side. In short, we want to protect you, the reader's,
right to complain. But, we also have the responsibility to
protect firms from damaging comments which may not be
their fault.
We feel, at least I do, that we have a responsibility to all
concerned.
Finally, on a less weighty topic, I want to formally
announce the beginning of the Rainbow Simulation
Contest.
We expect the Simulation Contest, in terms of prizes, to
be even bigger than the Adventure Contest for which the
winners were announced in January. We are aiming for a
special "Simulation Issue" this summer and we encourage
your entries. To that end, we plan to publish a couple of
Simulations to help you in the months ahead. But don't wait
f or them! Get going. We expect to set a May 30 deadline for
entries. And, the sooner you get working the better.

Stress E valuator: Coping
Techniques Called Helpful
Tension. Pain. Pound. Thump. Sounds like an old
familiar commercial tor a popular headache remedy. While
an analgesic may indeed cover up pain, it does nothing to
ameliorate thecoi/.veof'thepain.Takinga pain medication is
rather like cutting the wires to a tire alarm — it gets a lot
quieter tor a while, but watch out, the lire is still burning!
Today, the scientific community recognizes the powerful
role that stress can play in bodily discomforts and illnesses.
Headache, high blood pressure, lowered resistance to
infections, nervous breakdowns, stroke and even cancer are
some examples of conditions that may be caused or
aggravated by excessive stress. Like any delicate piece of
machinery, when the body is over stressed, bits and pieces
begin to break down. Inevitably, there are innumerable
prescription and non-prescription nostrums whose primary
effect is to suppress the symptoms of an over stressed body
and mind. It is all too easy to pop a pill or plop a couple of
dissolving tablets into a glass of water: in fact, the drug
industry heartily encourages you to do this with its high
budget advertising. The message seems to be: It doesn't
matter if you abuse your body, somewhere there is a pill,
tablet or capsule that will take care of your symptoms.
If a philosophy of pill popping does not agree with you,
there is an alternative: learn ways to evaluate your stress
level and learn techniques for successfully coping with
stress.
Petrocci Freelance Associates has recently released Stress
Evaluator, a cassette based program for the Color
Computer. The program incorporates questionnaires for
evaluating your stress level, evaluating your ability to cope
and assessing your comfort level. Also included are
instructions for reducing stress through a meditative
technique and a graphics screen to aid the process.
Stress can be physical or mental. Stress can be generated
from unpleasant situations. But did you know that stress can
also be produced by pleasant phenomena? The actual
causative agent in the production of stress is simply a change
from the status quo. Death of a spouse, divorce or getting
fired from your job could all produce stress; so could marital
reconciliation, retirement or an outstanding personal
achievement.
Stress in and of itself is neither good nor bad. A moderate
amount of stress is necessary for any achievement or
increased productivity. Stress has a negative effect only
when your ability to cope is exceeded. Stress Evaluator
helps you determine your coping ability with a separate
questionnaire. The program queries you on your virtues and
your vices. Are you stubborn? Are you tolerant? Do you get
upset easily? Your inmost secrets will be laid bare!
Naturally, the CoCo will keep strict confidentiality.
After evaluating your ability to cope. Stress Evaluator
will help determine your comfort or discomfort levels. You
will be able to know whether to balance your level of
comfort/discomfort for increased productivity or perhaps
you need greater relaxation. For example, a boxer in the
1 5th round is likely to be experiencing great discomfort but
high productivity in going the distance. If your coping
ability is high, you, too. may wish to increase your
discomfort level on the job thereby increasing your

productivity. If your coping ability is low, it may be wise to
decrease discomfort to avoid possible health problems.
Finally, the simple meditation technique (rhythmic
breathing) provided with Stress Evaluator may be useful to
those who wish to increase their coping ability. A sinusoidal
wave form is presented on the graphics screen. You inhale
on the rising portion of the curve and exhale on the falling
portion of the curve. Very simple indeed! But relaxing.
I found the Stress Evaluator relatively easy to use. The
colorful graphics output added much to the stress
evaluation session. Another useful feature was the printer
output of the various stress and coping factors. The software
is self-documenting to the point that some users may find the
extra written instructions superfluous. For the uninitiated,
however, here is a hint: the software is loaded in three
separate Fxtended BASIC programs. Each section must be
started by typing the RUN command. The main program
will tell you that another section is loading. When the load is
complete, the Color Computer will print out its familiar OK.
That is when you type RUN again.
Extended BASIC is required withat least 16K of memory.

Hackers Helper...
This Routine Draws Circles
Around The Rest, Randomly
This month's Hackers Helper comes all the way from
Humboldt, Saskatchewan, Canada — which, being north of
Moose Jaw and east of Saskatoon, is farther from more
places than most places.
Karl Germann, of Humboldt, writes, "This program is
designed to shorten time and save memory by inputting all
circle positions in a data statement... Use this method and 1
guarantee you that it will be worth the effort."
The secret to the beautiful patterns generated by the
routine is the random coloring. The main purpose of the
program is the REA D, DA TA statements. These are easy to
execute and run at impressive speed.
Karl is 15 and reports he has just begun experimenting
with CoCo. Keep on keeping on, Karl!

Let's Look At
Keyboard Input
By Richard A. White
Virtually all but the simplest programs are going to have
to get some information from the user. This information can
come from the keyboard, the joystick, a tape file, a disk file,
or some combination of these. First, let's look at input from
the keyboard. It is the first input source the new
programmer encounters. There are actually two
consideratons, how to input data and how to test and use
data immediately after it is input. Test? You've never hit the
wrong key? Or, if you have and nothing happened, the
program tested your response, didn't like it and gave you
another chance. How data is input may be determined by
how we are going to test and respond to the input.
Color Basic provides 1 N PUT and IN KEYS commands
for keyboard input. Extended Basic adds LINE INPUT.
Let's dissect them. Following are a number of INPUT
examples:
INPUT IS
INPUT I
INPUT "A CHA RA CTER STRING ".75
INPUT •ENTER NAME, AGE, W EIGHT AND
TELEPHON E";NA$,A, W, TL$

INPUT will accept either a character string or a numeric
variable. In accepting a string, it will lake up to the number
of characters the keyboard buffer will accept. Any number
up to 1 .70E38 may be entered. Numbers larger than this will
cause an OV ERROR (overflow) message as the program
crashes. A string can be used with INPUT to print a
message, generally a description of the data to be entered.
When the program encounters an INPUT statement, it
prints whatever character string it is given and a "?". It then
waits for a keyboard response. Note that a number of
variables may be strung out after an INPUT. In the fourth
example, the user could have responded:
7Jones,29,l82,900-6782(ENTER).
Each time I N PUTsees a comma or an ENTER it considers
it the end of data for the variable it is working on. An
alternate user response is to hit ENTER af ter each data item.
In this case. INPUT prompts with a double question mark
(??) for the next item it needs. Here is an example.
NAME, AGE, WEIGHT, TELEPHONE '.' Jones
?? 26
?? 1 82
?? 900-6782
INPUT is not for all occasions because of a few
characteristics that can be problems. It will not accept
commas or colons in a string entry and is of mixed mind
about dealing with quotation marks. It also forgets leading
blanks. Finally, when the ENTER is pressed, the rest of the
line is blanked and the cursor goes to the beginning of the
next line. This can be a hair pulling event when you have
spent time making an input menu super neat with color
background and borders and the I N PUT wipes part of it
out. For the beginning programmer, pretty menus are off in
the future. My advice is to learn, and use, INPUT though
you will probably want to use LINE/NPUTor INKEYSfor
most future keyboard entry. You will need it for tape and
disk file handling.
We said that commas, quotes and colons givestring input
problems. Let's look at a few quirks when inputting
numbers. One nice one is that //V/ > (77"overlooks spaces in i
numerical entry. You can answer the "?" with 100 247 89'
and INPUT w\\ make I = 100247892 as if you had typed i
that way. Entering a number with spaces can be easier an
improve entry accuracy. However if your finger slips so th;
what you enter is 100 24U 892 INPUT will quit when
comes to the "U" and return a stern ?REDO. Now this
okay if you're enteringscreen format. But if you have two
three variables after an INPUT and the error is in the th
one, INPUT throws out all and starts over with? RE DO. f
natural inclination would be to re-E NTER the offending
entry, but IN PUT wants all of them over again.
How does one find things like this out? With simple
experimentation. You can learn most of what you need to
k now about how / A' P (77" works by playing with the one line
program below. It is listed along with a sample session of
inputs and results. So, fire up CoCo and push keys with me.

LINE INPUT accepts only string inputs, one only at a
time. Any keyboard character can be typed and LINE
IN PUT will take it. Since the characters are stored in the
keyboard buffer before ENTERing, the back space acts to
erase typed characters and will not be stored, nor will the
erased characters. If you are writing a word processing or
data mangagement program in BASIC, LINE INPUT is
mandatory for keyboard input. Try writing English without
commas. For these applications, you most likely would find
a "?" printed before each entry a pain, so LINE INPUT
omits printing the "'?". If you want a question mark, you
have to put it into your character string. Only the following
two forms for LINE IN PUT are allowed. Note that a space
between LINE and IN PUT is optional.

Our experiments above have shown how we can enter
nearly any keyboard character into a string using LINE
INPUT. I leave it to the reader to experiment further and try
to prove otherwise. We also built some conversion to
numbers into the demonstration. We can do the same thing
with converting an INPUT produced string to a number
with identical results. The program bombs only when we try
to convert a string to a number larger than 1 .7E38. A keying
error like "234U" will not be detected without added code.
We would need to take a string apart and test it piece by
piece for errors and ask for re-entry if all is not right. You
need to make a decision on how important error trapping
and user proofing of inputs arc. There arc two levels. One is
catching data errors. The other is catching errors that will
break the program and which are much more important to
find.
Generally, input testing is best done on a character by
character basis, though each need must be evaluated
individually. Where user proofing or testing a short
sequence of characters is the objective, IN KEYS is a
convenient tool. Its syntax is Z$=INKEY$. INKEYS checks
to see what if any key has been pressed since the last
INKEYS and program execution proceeds. If there has been
a keystroke, Z$ will contain the character, otherwise Z$="".
Since program execution proceeds, it is generally necessary
to put INKEYS in a loop that is exited only when a key is
pressed. In other cases, generally games, the loop will
contain code causing continuing actions on the screen as
well as the I N KEY sampling so that the program docs not
wait for a player's response, but checks frequently to see if
there is one. Below is a typical data input INKEY loop.

INKEYS may be used frequently in a program for a variety
of purposes and is profitably placed in a low numbered
subroutine for speed and memory saving. The code should
also be kept to its simplest form with most data
manipulations done by the calling routine. One exception is
to convert Z$ to the number Z since numbers are frequently
used as responses to menus and then decoded using ON Z
GOTO frequently used as responses to menus and then
decoded using ON Z GOSUB statements. The following
modification fills the bill.
10 Z$=INKEY$ :1F Z$=""THEN 10 ELSE Z=VAL(Z$)
:RETURN
Now that we have a single character input, how can we use
it. The simplest application is to get and act on a single
keystroke response to a menu.
MAIN MENU
1. INPUT
2. PRINT
3. LOAD
4. SAVE
5. QUIT
If line 1000 printed the menu, the next lines might be as
follows.
1010 GOSUB10 :ON Z GOTO 100, 200, 300, 400. 500
1020 GOTO1010
I f Z is greater than five, o r Z equals zero, the program goes
to 1120, which goes back to 1010 to get a new entry.
The use of a command line at the top or bottom of a
working screen is a user-friendly device to remind the user
what control options are available and the keystrokes
required to invoke one. In an example from an information
management program, the user has just finished entering a
record, in either upper or lower case mode, and needs to tell
the program what to do next. Options are to continue data
entry, modify the record just entered or return to the main
menu. This command line is presented:
CONTINUE mODIFY rETURN
The lower case (reverse video) signals the key to press for
each function. Now we need to convert one of the letters "c,
C, m, M, r, R"to an action. A neat way to do this that avoids
a bunch of IF THEN statements is to use INSTR as follows:
250 GOSUB10 :Z = 1NSTR(1, "cCmMrR",Z$) :
ON Z GOTO 200, 200, 500, 500, 1000, 1000
255 GOTO250
If Z$ is not one of the control letters, INSTR returns a 0 and
the program tries again (Line 255). If a valid letter is
returned, INSTR returns its count up the string and this
number can be used directly in an ON Z GOTO or GOSUB.
The Syntax of INSTR is fairly straightforward, the " I " tells
INSTR to start at the first character of the string. Sorry
Color BASIC people, INSTR is one of those Extended
BASIC jewels, but you can write a short subroutine using
M1D$ to do the same thing. Our Apple friends have to do
that all the time.
Another testing task might be to see that only numerals or
a period are entered into an accounting routine and
recognize the carriage return to end the input. Here is code
to do this:
250 GOSUB10 :Z = 1NSTR(1,"234567890.",Z$) :IF Z 0
THEN
PRINT Z$; :A$=A$+Z$ :GOTO250 ELSE
IF Z=0 AND Z$()CHR$(I3) THEN 250
Here if Z$ is a number or a period, Z$ is added to A$ and Z$
is printed to the screen with a semicolon to hold the cursor.
If Z$ is not anumber and it is not a carriage return, the
program disregards the input and goes back for another
character. The only other possible case is that Z$ is a
carriage return and the program goes to the next step.
Routines like this which are continually getting a
character and adding it to a string generate a lot of garbage
in string space. The program must stop occasionally for the
computer to clean things up and make room for new strings.
This is a major reason not to use INKEYS for extensive
string entry such as in a word processor or data file program.
Now for the homework assignment. Suppose you have
written a Bulletin Board program and some jerk at the other
end of the phone line has discovered he can crash your
program by answering I E40 when the program asks for the
number of the message to be read. Write an input and error
trapping routine to recognize and discard an out of limits
number. Assume that your Bulletin Board is so good that
you expect I0E30 messages over the next ten years. (If you
believe that, 1 have a bridge for sale!) The best routine(s) sent
to the Rainbow will be published in a later BIT S AND

Software Review...
Frog Trek Hops
Over High And Low Ground
Frog Trek is a program based on the arcade game
Frogger. The object of Frog Trek is to guide your frog (using
the keyboard) from the left side of the screen to the right
side, without getting killed in the process. Sound easy? It
really isn't, since you must shift your way through six lanes
of rush hour traffic, dodge a threatening snake and hop from
logs to turtles to the frog's home. Once four frogs reach their
destinations, a new screen is drawn with faster traffic and a
faster river current. After many hours of playing, 1 was only
able to accomplish this screen once.
As is the case in most computer programs. Frog Trek,
which requires 1 6K, has its good and bad qualities. Here are
a few features and disappointments contained within this
machine language program.
Graphics — The Graphics in Frog Trek are one of the
program's attributes. The shapes are very clear and distinct;
the frog looks like a frog, the turtles look like turtles, etc.
Despite the many objects moving on the screen at once,
there is no flicker. The program's author did a good job with
the graphics in this game.
Sound — Sound is a vital part of any arcade program.
Unfortunately, Frog Trek falls short in this area - nothing
but short beeps and long beeps of different pitches. The
documentations says that "if you succeed in bringing froggie
home he will reward you with a friendly R 1BB-1T." To me,
this "RIBB-IT" seemed more like an alarm clock sounding
off. 1 personally feel that the sounds should have been
developed more thoroughly.
Documentation — The instructions included with this
game are adequate. They tell how to play the game in an
understandable manner. There were a couple of things I
found missing from the documentation. There was no
mention of scoring. I had to figure this out myself. Also,
there wasn't any statement regarding the purpose of the
timer. I believe the directions can be improved.
Bugs In The Program — To be honest, Frog Trek needs
some major debugging. The bugs aren't that major in the
game play, but at times are quite distracting. There are three
problems worth noting. First, a few words of instructions
are displayed before each game. This is f ine, but the problem
is the way it is written on the screen. It is shown like this:
USE ARROWKEYS TO CONTROL THE FRO
G HIT ANY KEY TO START GAME
1 feel a quality computer program shouldn't have this
program. A few more programming instructions would
have cured this silly mistake. Second, once the timer runs
down from sixty to zero, the computer thinks that the frog
has reached its home. You are awarded 90 points, the frog
goes back to the start, and best of all, yourfrogdoesn'tdie. 1
don't mind this, but I would have found the game more
challenging played against time. Finally, the problem 1
found most distracting was something that prohibits your
frog from getting across sometimes. Once your frog reaches
the middle island, it must jump from log to turtle. Well,
sometimes the frog lands directly on top of the log or turtle
and dies. Other times, the frog is not quite on the object and
lives. This became more frustrating the more 1 played.
Despite these problems, I found Frog Trek to be enough
of a challenge for the price. It seems to me that the author
rushed his product out onto the market a little too quickly. If
he were to work on his program a bit, and take some time
debugging it, Frog Trek could be turned from a good
program into a great one.

EDUCATION
4K, Non-Extended
Tutor Spells 'Help'
By Ronald Pesha
Here is a program I developed to help my 10-ycar-old son
practice his spelling. It is unusual, as I see it, in that the
words are spoken to the child. It also scores the child and
prints out the scoring at the end.
An important aspect of this program is that it requires
only regular, not Extended, Color BASIC, and 4K is more
than adequate. A cassette recorder is required, and two
cassettes. Load the program on one cassette, using your own
list of words. I have put a sample list of 20 spelling words in
the program beginning with Line 100; just use DATA at
Lines 100 to I 1 9 at the rate of five words per line. If your list
of spelling words has more or fewer words than 20, you will
also need to change Line 1 30 and Line 220 as explained by
the REMARK after each.
Now place a fresh cassette in the recorder and ENTER
RUN 1000. Just follow the instructions. Speak the list of
spelling words, in exactly the same order, into the
microphone, following the instructions which will appear on
the screen. You'll find that it is easy to change this cassette
and the DA TA lines in the program each week for the child
to practice.
Type the program listing with spaces exactly as shown for
the best appearance on the screen.

Hardware Review...
Atari Joystick
Adapters Endorsed
What is your high score at Donkey King'! What'.' Well,
there goes that theory. I was assured that alter using an Atari
joystick with the CoCo, my game scores would show a
remarkable improvement. The only problem is that 1 no
longer have thedexterityofa 10-year-old, semi-professional
game player. At the same time, I am strong enough to tear
the stick right out of its socket in frustration. 1 would
recommend to anyone who enjoys games on his CoCo, that
he invest in an adapter for converting the Atari joystick to
the CoCo.
Many different manufacturers are now producing plug-
compatible interface units for the true game addicts who
spend hours trying to squeeze another 100 points out of their
computers. As I happened to have more invested in Atari
cartridges than in my computer — well, almost I was very
interested in the operation of these units. Two similar units
were reviewed. The first was a single stick interface termed
Top Sli.x by International Software. The second was the
Double Slick Interface by Spectrum Projects, featuring two
joystick ports. The Double, as 1 call it, comes with optional
Atari joysticks. Both units performed as they are advertised.
The Double is housed as a 4"x2"x I " heavy plastic box that
contains the Atari jacks. This unit is connected by two 36-
inch cables to the joystick ports in the rear of the CoCo.
To say the least, this unit is "quality" contstructed.
Unfortunately the Top Slix unit I reviewed is a demo, so 1
cannot comment on the final product.
Both units performed equally, but I picked up some extra
noise on my TV screen with the Double in the line. After
moving cables all over the place I gave up trying to
completely eliminatethe problem. I feeltheextra lead length
invites problems.
Now, for the problems. As you may have guessed, there
are certain disadvantages to the use of an Atari joystick for
certain games. The Atari units have switches instead of
potentiometers inside the black box. What this means is that
you don't have a linear or continuous output when you
move the handle from right to left or top to bottom. Another
way to look at it is to plug in your diagnostic program and
look at the position of the joystick is either going to be in the
middle of the screen or on one of the edges. There are no
positions in between. What does this mean'?
Well, for certain games, such as Donkey King or one of
the Pac Man derivatives, where you just have to move to the
right, left or up and down, it is insignificant, but what about
Polaris or FootbaW. These types of games require
continuous (linear) motion.
In summary, I say again that 1 recommend these unitsto
anyone interested in action games. After reviewing my
software library 1 found very few games that would not be
compatible with the Atari joystick. Also, in my opinion, the
ruggedness of these joysticks is a consideration when
compared to some other products on the market.
Now if I could only get to the second screen!

Bigfoot: More Board Game
Than Adventure
"Deep in a dark and twisting maze, hiding in his lair,
Bigfoot waits to ambush careless hunters who enter his
domain."
So begins the documentation for the Bigfoot adventure.
The object of this game is to find your way through a maze of
rooms and passages to Bigfoot 's hiding place and kill the
monster. Along the way, you must avoid rooms filled with
quicksand which immediately swallow you up into oblivion
if you make the mistake of entering the room. Another
potential hazard is a room with a giant bat. The bat may or
may not be disturbed by your entering the room. If it is, it
will pick you up and drop you randomly in another room.
When you locate Bigfoot using the clues the game provides
you get one shot to shoot into his lair and kill him. If you
miss, the noise irritates him and he stomps on you — score
one for the Sasquatch.
If you accidentally stumble into his lair, he stomps you
before you can even think about shooting him. The game
plays fairly quickly, usually taking less than five minutes to
either kill or be killed. At the end of each round a three
entry-score is displayed — "Hunter" (that's you), "Bigfoot,"
and "Quicksand."
Although the game is presented as a graphic adventure, it
plays more like a video board game. The graphics do not
display large rooms or dark passages. The rooms are small
squares just large enough to hold the figure of the hunter.
The entire maze, which could consist of up to 42 rooms, will
fit on one screen. The "dark and twisting passages" are
connectors between these rooms. There are three levels of
difficulty for the mazes and four types of "mapping" for the
hunter's movement through the maze. In normal mapping,
when you begin a new maze you are randomly placed into
one of the rooms and that room and its position are the only
things displayed on an otherwise blank screen. As you move
by use of the arrow keys to other rooms, each new room you
enter is added to the display. In blind mapping, only the
room you are in is displayed — all others are blanked as soon
as you leave them. The blind mapping is certainly more
challenging, trying to remember the relative locations of the
rooms you have explored and their clues to Bigfoot's
location.
Besides myself, our family has three expert game critics —
1 6-, 1 4-, and 12-year-old sons. When 1 polled the boys for
their opinions, the 1 6-year-old said, "It's OK." The 14- and
12-year-olds agreed that it was "pretty good."
They, of course, have many friends to assist them in their
game playing. The greatest interest in Bigfoot came from the
1 2- to 14-year-old group. If you are a true adventurer along
the lines of Colossal Cave or the Scott Adams adventures,
Bigfoot is not what you are looking for. If you are a board
game enthusiast and appreciate the extra dimension that a
computer can offer through its graphics and ability to
dynamically control the board, you may enjoy Bigfoot.
Bigfoot is written in Extended Basic and requires 32K.

ColorCk! It's not the N BC peacock, but it is this month's
winner of the Roy G. Biv Award.
Here's One
For You, Roy
Here's a short, no nonsense program that we're quite sure
Roy G. Biv, wherever under the sun he may be, will heartily
endorse. Thus, the editors of the Rainbow, after due
deliberation and reflection, have tapped out David A.
Cromley, of Cheyenne, Wyoming, as the first recipient of
the Roy G. Biv Award.
While David is the very first to be recognized with this
special citation, the editorial staff of the Rainbow fully
intends to confer this acknowledgement of meritorious
service to others who make significant contributions to the
Color Computer community (or who send in nice little
programs that we like and think would be helpful to our
readers). We believe it is a fitting tribute to Roy G. Biv,
whose legendary and colorful name is known by heart,
associated with happiness and recalled with fondness by
friendly people in all walks of life, most anywhere the sun
shines and the rain falls.
In offering to share his short listing with Rainbow
readers, David A. Cromley writes, "Here is a little utility I
frequently use to check the adjustment of the TV set. It also
helps when 1 can't remember what magenta and cyan look
like. Hitting the keys '0' through '8 'changes the background
color."
Here at the Rainbow, we enjoy "program quickies" such
as David's ColorCk, and we hope to receive and print a lot
more of them.

GET YOUR BUGS
OFF YOUR HANDS
Bugs in your programs can really get under your skin. Especially when they've
been bugging you for longer than you'd like to think. wl
So get your bugs off your hands. And onto somebody else's.
Pack them off to DeBug. (On cassette, thank you.) With a description of where you
were going. And where you got stuck. If it's an interesting enough program, we'll send it to
people who like to stomp on other people's bugs.
If somebody can get all the bugs out of your 16K Extended Basic CoCo program,
we'll try to sell it. And everyone shares the profits
Send $5 per entry. Or $9 for a sample cassette of
20 or so very buggy programs. Or $12 for both.

Welcome to the March column. 1 wish 1 could say that 1
finally did this early, but the fact is that as I sit here at my
computer, word-processing away in an effort to spruce up
this final draft, the people at Federal Express are only two
hours away. Yes, the editor of this most respected magazine
said "it absolutely, positively had to be there overnight."
That's what I get for waiting until the last minute.
As you know, we have been developing a plan for our
major record keeping program over the last two months,
and the "finished" program is below. 1 put finished in quotes
because 1 know that no program is ever really finished. The
programmer may think it is...
YOU'LL BE SORRY IF YOU DON'T READ THIS NEXT
PART!
The program runs on a 16K Extended BASIC machine —
OH NOOooo. _ _ _
Someone said as I deno'd C. C. Calc at the last meeting of
the Northern Illinois Computer Club, "I just spent twice
as much for half as much." He bought a copy anyway
Save, Load, and Merge files - Yes) User specified Decimal
Points? - Yes! Can you calculate 31 of %U,iU but not
exceed tl50? (Sound like the IRS?) - Yes! Stuck with Row
and Column formulas? Not with C.C.Calc! Every cell on
the spreadsheet can have its own formula.
C. C. Calc is the full featured, Electronic Spreadsheet
that's designed for maximum, user controlled, flexibility
on the Color Computer. The Command Summary fills three
pages of the documentation but in short you have all the
arithmetic operators, summation, replication, calculation
order, selected column prints, screen prints and more.
Now the Color Computer has Smarts to match its muscle.
C.C.Calc is available on cassette or disk for a
ridiculously low $25.00. Requires 32K.

Create Character Files
With This 'Finished' Program
By Bill Nolan
Rainbow Contributing Editor
barely! Before you type it in type POKE 25,6:N EW and
ENTER to get the most memory, and then type this again
every time before you load the program or you will get an
OM ERROR. Ifyouonly have a 1 6K machine I recommend
the following: Leave all REM lines out of the program
(except line 1 1 000 — we jump to that one), and when it is all
typed in and working, renumber it by typing R EN U M 0.0, 1
and pressing enter. This will make more memory available.
Of course you saved it to tape first in case the computer
crashed while renumbering. You can then change the
CLEAR in line 5 to be CLEAR 1200J6344.GOSUB.
If you have 32K, change line 5 to read CLEAR
200QJ2344:GOSUB... Also change line 20 to read FOR
j*r>32345 TO 32383:READ...and change the number 16345
in line 1 1 032 to 32345. This will get you all kinds of memory
for those changes you'll want to make.
If you have disk, you will have to have 32K to use this
program (unless you unplugyourdisk controller). Make the
changes listed above for 32K machines, and in addition
make the following changes in several lines between 1000
and 2000. Every time you find a CL.OSE #-1, OPEN #-1,
PRINT #-1, or IN PUT #-1 , delete the minus sign i n front of
the one. Also, you will want to change the PRINT in line
1030 to something more appropriate such as "MAKE
SURE THE PROPER DISK IS IN DRIVE I, ANDTHEN
HIT ANY KEY TO GO ON."
Now. on to using the program. This program will create
and update character records for fantasy games. The
operation will be fairly obvious when you run it. but a
couple of notes are in order. It allows you to enter up to 60
spells and non-magical possessions, and up to 20 magic
items. It sorts the magic spells by level, and it allows you to
make changes or deletions easily before saving a character
record to tape or disk, or printing it on the screen or printer.
It does not store thieving ability scores since you don't
enter them. It computes them when you select "8" on the
main menu, so if you print out the information before
selecting number 8, all thief scores will still be I. Just make
sure that you go to number 8 before printing out the
character information.
This program POKEs a short machine language routine
into memory. All of the DATA for this routine is in line
12050. This little routine puts a nice border around the
screen whenever you call it, and it does it instantly! The
border can be changed by pokinga value otherthan 169 into
memory location 346. The program does this POKE in line
20, so just edit that line to get a different border design.
Values above I 28 are best, but values about 255 will result in
an error message. This routine is 37 bytes long and is in
position independent code, so if you use it in another
program you can put it wherever you want it.
202 the RAINBOW March. 1983
YOUR COLOR COMPUTER JUST GOT WHEELS!
REVOLUTION!
You accelerate hard down a long straightaway,
braking heavily at the end for a hard corner.
You slice smoothly through the esses, and then
boldly keep the power on for a fast sweeper.
The Ferrari drifts dangerously near the edge,
but you make a tiny correction in the steering,
and you are through.
The finish line flashes by, and suddenly you
are in the pits. The car falls silent. You see your
lap times being held up. Your final lap was a
new lap record! At last, you permit yourself
a small smile.
You have mastered this powerful car on a
difficult track, driving with the assurance and
precision that comes only from long hours of
practice.
You are driving an authentic race car. You are
playing Revolution!
FANTASTIC ACTION
Revolution uses high resolution, machine language graphics
for action that is smooth and fast. The emphasis is on
authenticity in the control and motion of your car. As in
driving a real race car, accuracy and precision in your driving
are what counts. Frills and non-essentials have been left out.
PURE COMPETITION
Like a real race driver in practice and qualif ying sessions, you
compete against the clock and against the existing lap record
for that track. Revolution records the lap records and the
name of the person who set the record, so you always know
who reigns supreme on your favorite track!
DESIGNED WITH YOU IN MIND
Revolution is menu-driven, and self explanatory. Informa-
tion screens tell you what you need to know. When you're
ready to play, a menu of the names of all your tracks is
displayed, along with the lap record for each track and the
name of the person who set that lap record. You select a track
with a single keystroke, and Revolution takes you there.
A NEW CONCEPT
Revolution is a unique game, because it allows you to create
the most important part of any race game: the track itself.
The first time you run Revolution, you will be able to choose
from several tracks and cars which are included with the
game.
But, with Revolution, this is only the beginning! You can
create as many tracks as you like. You can make each new
track as difficult or as easy as you wish. You can make easy
ones to begin with, and tougher ones as you become more
skilled. You may find creating tracks to be almost as much
fun as driving on them!
You can save your favorite tracks to run on again whenever
you wish. Revolution will automatically add these new tracks
to the menu. And you can exchange your favorite tracks with
other Revolution owners.
Be caref ul, though, about letting your f riends play this game.
They may not want to let you have your computer back!
THE EARLY REVOLUTION
A prototype version of Revolution was published in the
September, 1982 issue of Rainbow magazine, under the
name The Track. The response to The Track has been terrific.
Revolution has all the features that have made The Track a
favorite, and Revolution's fast, high-resolution machine
language graphics are dramatically improved over the
prototype's.
REVOLUTION NOW!
The original Revolution for the TRS-80™ Color Computer
requires 32K and one disk drive. A new cassette version has
action just like the disk version, and similar track-saving
features excluding a menu of available tracks. The cassette
version will run on a 16K Color Computer or TDP-100. You
can upgrade to the disk version later, too, for a nominal fee.

The print routine located at lines 2000 to 3000 takes
advantage of a feature of the Color Computer which isn't
mentioned anywhere 1 have seen. All of the accessories are
addressed by the computer by referring to their device
number. The disk drive is device number 1, the cassette is
number-l, and the printer is number -2. Well, it happens
that the television screen is device number 0, so you can print
on the screen by doing a PRINT # 0, just as you would print
on a printer by doing a PRINT # -2. You can also use a
variable as the argument, as in PRINT # DV, and the output
will go to the screen or printer depending on the value of the
variable. By using this, the program will print on either the
screen or printer and yet needs only one print routine. It just
asks where you want it printed and sets the variable
accordingly.
In the print routine 1 didn't use any control codes to make
the print-out fancy. This was on purpose. (Really!) The
control codes vary from machine to machine, and if your
printer was a different brand from mine they wouldn't work,
so if you want to get fancy on your own. have at it!
There is a two line section at 7300 and 73 10 that sorts the
magic spells by spell level. This routine is a very simple and
short example of a bubble sort (a slow kind of sort, but easy
to do) that would be practical for a list up to 100 or so entries
long. The same general form could sort most anything.
1 hope you will have as much fun using this program as 1
did writing it. It stores the files under the character name, so
you should be able to put more than 50 files on a disk. If you
have more than one on a tape, it will search the tape until it
finds the correct one. 1 guess that wraps up this project, so
we'll see what next month brings. If you have any
suggestions write to me in care of Prickly-Pear Software,

THE STEREO COMPOSER
THE VOICE
The STEREO COMPOSER music synthesizer was developed for the true music
lover. All the features available for the COMPOSER described below are also
available for the STEREO COMPOSER. However, instead of using the single 6 bit
digital to analog converter built into the computer and the speaker built into your
TV, the STEREO COMPOSER uses two 8 bit digital to analog converters which
drive two audio power amplifiers. These amplifiers supply enough audio power
to easily drive your own external speakers. If you like, the output may be con-
nected to your home stereo system to further increase fidelity. Connection is
provided by two phono connectors. If the music is too loud, two built-in volume
controls are provided to allow you to control the volume of each of the channels
separately The advantage of being able to use external high quality speakers is
obvious. The use of higher quality digital to analog converters serves to further
increase music fidelity.
The STEREO COMPOSER produces music in stereo. Of the4 voices produced. 2
are directed to each channel This ability alone increases the realism of the
music. You can even move the voices between speakers as the music plays.
The STEREO COMPOSER comes assembled, tested, burned in, with all the
software and hardware to allow you to immediately start enjoying your music. A
complete manual and examples are provided to give you everything you need to
know.
The STEREO COMPOSER is completely memory decoded so it does not conflict
with the Radio Shack disk controller. In this way, disk owners with an expansion
interface such as the BT-1000 by Basic Technology can produce music from disk
with the STEREO COMPOSER in one slot and the disk controller in another. In
fact you can even have THE VOICE in another slot without any fears that there
will be memory conflicts.

STEREO COMPOSER (Hardware and Software)
THE COMPOSER
The COMPOSER is a4 voice music compiler which easily allows one to develop
high quality music. Each voice is programmed separately. In addition, each
voice uses its own waveshape table which means a unique sound for each of the
4 voices
The COMPOSER features a 7 octave range. It supports dotted and double dotted
notes as well as eighth, quarter, and standard triplet notes. Sixteenth and thirty
second notes are also supported.
The COMPOSER allows the music to be played at any tempo and in any key And
believe it or not, the tempo arid key can be modified as the music plays. This
gives the user tremendous versatility in developing music. Key modification also
allows the user to move the music up or down one or more octaves.
The COMPOSER displays a constantly changing random kaleidoscope pattern
as the music plays. In addition, the number of the note being played is displayed
which aids one in finding sour notes during music development. Both of these
displays can be disabled to allow any screen to be displayed while the music is
playing. In this way, one can show the words to a song or display a picture as the
music plays.
The COMPOSER develops a machine language position independent sub-
routine that can be Saved, Loaded, and Executed independent of all other
software. This means that you can shareyour music with friends. In fact, you can
write your own BASIC programs that call and play the music. Software vendors
may include the music in their own product.
The COMPOSER is menu driven making it extremely easy and friendly to use and
operate. A thick operating manual is also provided. Many examples are given to
aid the user in getting started. All you need is provided, no additional hardware is
necessary. Don't let the price fool you, the COMPOSER has got to be heard to be
appreciated.

SPEECH SYSTEMS got its start providing high quality speech synthesizers for
SS-50 bus computers. We are now proud to announce the same high quality
product for the Color Computer and TOP-100.
THE VOICE should not be mistaken with software speech synthesizers which
require the computer to do all the work in producing speech
THE VOICE uses a special large scale integrated circuit, the SC-01 by VOTRAX,
to reproduce any one of 64 phonemes at 4 inflections. Phonemes are basic units
of speech which allow one to reproduce any word in English as well as many
other languages.
THE VOICE has two outputs. Speech may be heard through the user's TV
speaker, or the built-in audio power amplifier may be connected to your own
external speaker A phono connector is provided for this purpose and if the
volume is too high, a built-in volume control may be used to adjust it to the
proper level
THE VOICE comes assembled, tested, burned in, with all the necessary
hardware and software. A complete manual with many examples are provided to
get you started in developing your own BASIC or machine language programs to
use speech.
THE VOICE is completely memory decoded so it does not conflict with the Radio
Shack disk controller. In this way. diskowners with an expansion interface such
as the BT-1000 by Basic Technology can produce speech from disk with THE
VOICE in one slot and the disk controller in another. In fact, you can even have
the STEREO COMPOSER in another slot without any fears that there will be
memory conflicts.
We are trying to develop a library of software for THE VOICE Toward this end, we
will be offering substantial royalties to software authors for their work.

Software Review...
Wormhole Is
High-Energy Graphics Game
Now you can tour the depths of space through the miracle
of Wormhole. a game combining natural curiosity w ith the
color and imagination of the new technology to give you an
inside look at what goes on in one of those "black holes."
.lust climb aboard your spaceship with FTL (faster than
light) speed for an adventure.
Wormhole is a space game which derives its title from the
space-time surrounding the ship, which, in theory, is formed
in a "tube." similar to that inhabited by Eart hbound worms.
As you zoom into the meandering tube, you start collecting
points because your ship collects "gold dust" that is formed
when the FTL drive compresses space-time into the v acuum.
As you attempt to negotiate the course, you are subject to a
barrage of gold nodules, which appear when you least
expect them. Blasting them into bits transforms them into
valued objects, giving you one to nine poin ts for each piece
captured in the handy "jaws" attached to the nose ol your
spaceship. If you are careless and collide with one of them,
however, your ship will suddenly drop below light-speed
and sustain major damage, costing up to 50,000 points.
The ship is controlled by the right joystick, and easily so, I
would add. The problem is when you take your eyes off of it
for a second to check your score in the upper right part of the
screen: Crash! Blinding lights! The ship blinks off and on,
hangs for a second and the screen echoes disaster, displaying
a dazzling array of color that is rivaled only by 2001: A
Space Odyssey.
There's really no problem, because as the screen says, you
can press any key to continue. You only lose 50.000 points
when you're knocked out of the hole. You start with three
million and it's easy to recapture lost ground with a feature
that enables you to gain speed during the game. Simply
pressing "S" allows you to slow down if you feel you're
losing control.
If the telephone rings and you're forced to leave the game
for a few minutes, pushing the BREAK key allows you to
freeze the game and retain your points until you return. It's
also useful if you feel you're losing your concentration. The
game does proceed rather rapidly and you are on constant
alert.
You are able to move your ship faster by moving it up and
down with your joystick up or down and backward and
forward. The "bursts" of speed gained via this method are
recorded in the lower left part of the screen.
Another feature you'll like, and which may explain why
you may need to use the BREAK key occasionally, is that
there is no real end to the game unless you get a minus
score. Scores above 10 million are possible for the expert,
but if you go over that figure, the scoreboard will display
characters whose codes are 58 and higher (inverse colon ":".
etc.). The window can hold only eight characters.
The creators of this fascinating game have been
thoughtful enough to see to it that as many of us as possible
can enjov Wormhole. providing different commands for
16K Color BASIC, for 16K Extended BASIC, and, for
those fortunate enough to have 32K. The man himself. John
Bobst. explains that the set-up differences arc needed
because the game uses the area from 7I6X to 163X3 for
program and Hi-Res screen. For 16K either BASIC or
Extended BASIC, the hardware stack would be wiped out if
the stack moved up. For 32K systems, the stack is initialized
much higher up in memory and is safe from being
overwritten.
Showing a strong trust in CoCo owners, Bobst graciously
provides details on how to CSA VEM (cassette) or SA VEM
(disk) a game in progress or to make a backup copy, insuring
that his creation will have a long life.
Wormhole is well-conceived playing wise, has great
graphics, strong sound effects, and w ill keep you transfixed
for hours that pass by quickly.

" TRS-80 COLOR COMPUTER PRODUCTS "
" THE 1 248-EP EPROM PROGRAMMER "
The 1 248-EP EPROM PROGRAMMER is a full. function unit that is
compatible with virtually all popular 1 K.2K.4K&8K -by-8,24 pin. 5
volt EPROMS. Compatible devices are 2508's, 2758 -O/1's.
251 B's, 271 B's, 2532's, 68732-0/1's, 68764's, and B876Bs.
Components 2732, 2732A, 25B4, and 2764 are compatible via
adapters (not supplied). The programmer is totally menu driven by
resident position independent firmware in EPROM, which makes it
suitable for experienced computer operators and novices alike.
Select the device type to be programmed from the device menu.
Next, select the function to be performed from the function menu.
On your command the 1 248-EP will verify EPROM erasure, com-
pare EPROM contents to specified contents of RAM or ROM,
program blocks or individual bytes of EPROM memory or copy ah
EPROM's contents to user specified RAM.
The 1 248-EP plugs into the cartridge slot of the Color Computer
and is invoked by the user with the "EXEC & HCOOO" BASIC com-
mand. The 1 248-EP contains its own on-board programming power
supply, and has a quality "Zero Insertion Force" socket.
The combination of the TRS-80 Color Computer , an editor/as-
sembler/monitor such as the Micro Works SDS80C-"— and the
1 248-EP EPROM programmer, makes a high performance, cost
effective software development station for MC-68OC76809
microprocessor based systems. Use the system tostoreyourown
games or utility programs in EPROM's for execution from the cart-
ridge slot using the CK4 PROM/RAM card described below.
The cost of the 1 248-EP EPROM PROGRAMMER, instructions
and adapter diagrams is just $99.95.
" THE CK4 PROM/ROM CARD "
TheCK4 works with2K,4K or 8K-by-B ROM'sorEPROM'softhe5
volt only variety in 24 pin packages. In addition, the CK4 may be used
with 4 static RAM's such as B116's to expand the computers
memory work space by 81 92 bytes. Each of the four on-board soc-
kets can be decoded to any 2K block of the memory map from
SCOOQ through $F800 of the Color Computer. In addition, each
socket can be configured to respond to address blocks from 2K to
8K bytes in length, thus accommodating 2K, 4K or 8K-by-8 ROM's,
EPROM's or RAM's. ROM and RAM can be mixed on the card as
well. RAM, on the card, can be written to and then "write protected"
via dip switches on the CK4 to emulate ROM.
The instructions include information on how to set up the socket
decoding circuitry and how to provide battery backup for programs
stored in CMOS static RAM on the CK4 with the computer off or
the cartridge removed.
The popular CK4 PROM/RAM card is now available in three
versions.
1) The full featured CK4 remains the standard of cartridge board
flexibility with the added capability of providing battery backup for
CMOS static RAM's such as 61 1 B's. Cost of the CK4 is still just
$29.95.
2) The CK4-1 is a ROM only version of.the CK4 card for use with
CoCo's with later than "E series" circuit boards. These later ver-
sions of CoCo are not able to write to cartridge based RAM without
modification. Cost is $27.95 for the CK4-1
3) The CK4-2 is the unpopulated CK4 series circuit boardonly. Buy
this version of the CK4 and configure thelm to meet your specific
requirements at a price designed to stretch your dollars value. Cost
is $15.95 each.
"MORSE EMCODER/DECODER KIT"
The MEDK80 Morse En/Decoder Kit consists of a machine code
software driver on tape, a schematic diagram of the interface cir-
cuitry, component parts, a printed circuit board (PCB), packaging
suggestions and complete instructions for building a Morse code
transmission and reception system that is compatible with 4K
RAM and up models of the TRS-8Q Color Computer
The transmitter/receiver interface circuitry is totally optically
isolated and is, therefore, compatible with all receivers and trans-
mitters. Transmitter and receiver both connect to the interface
unit and to the Color Computer via the RS-232 port.
The MEDK80 Morse En/Decoder kit operates at speeds up to 70
words per minute and automatically adapts to speed variations of
the sender. When transmitting, words are transmitted only when
fully formed, i.e., followed by a space, and the transmit text buffer
gives visual notification to the operator of what word/ character is
currently being sent. In addition, the text buffer is 51 2 characters
deep, which is sufficiently large to keep up with the best of "rag-
chewers"
Potential purchasers of this product should have previous kit
building experience. However, this is not a kit of great complexity,
and is well within the abilities of those actively involved in amateur
radio or electronic hobbies to construct. To reduce the chance of
wiring errors, component placement is indicated on the PCB and
detailed assembly instructions are included.
The cost of the MEDK80 software, parts, and instructions is
$39.95.
" COCO" GETS A BREADBOARD
The COCO BREADBOARD is a circuit board that plugs directly into
the cartridge slot of the Color Computer and provides the userwith
16 square inches of predrilled breadboarding area for circuit de-
velopment, interfacing experiments, motherboard implementation,
or whatever your imagination conjures up. The plated thru holes in
the breadboard are wirewrap pin compatible and on 0.10 inch
centers.
The COCO BREAD BOARD brings all of the data, address, and con-
trol signals available at the cartridge slot outside of the body of the
computer and the signal lines are appropriately labeled to facilitate
error free wiring of breadboards. A ground plane is provided on the
top side of the board and solder pads are provided on the bottom of
the board, thus facilitating circuit grounding and point-to-point
wiring. In short, the COCO BREADBOARD was designed with the
experimenter in mind.
The COCO BREADBOARD is attractively priced to justify its use
for even the lowest budget pro|ects. It is an ideal vehicle for learning
interfacing techniques. Buy extras to have on hand for those rainy
weekends.
The COCO BREADBOARD costs |ust $1 9.95. Price for two (2) or
more is $1 6.95 each.

"Pac" Up
Your Scuba Gear
Nibbler and Ms. Nibbler, by Thomas Czarnecki, are a
matched pair of maze games in which the scene of the action
is an undersea pearl bed and you are a hungry oyster merrily
eating sand to make your pearls. But, all is not well in
"oyster-dom," for lurking in a cave in the center of your
pearl bed are three Sand Monsters who just love raw oysters.
Your only hope for survival is to evade your pursuers until
you can get to one of the four Magic Catalyzer pellets which
lie in the four corners of the maze. Then you become not
only immune to the Monsters, but also suddenly hungry for
lheml Well, if this scenario doesn't seem vaguely familiar,
then you obviously haven't been inside an arcade in quite a
while.
Both of these Machine Language games are basically the
same except that Nibbler uses color-set one while Ms.
Nibbler offers color-set two, a different maze and Ms.
Nibbler wearing pink lipstick. The programs are auto-
executing with very good title graphics that really show what
can be done with Color BASIC'S CHR$ graphics. The
animation is smooth with very little flicker and the game
graphics are good, especially the Sand Monsters, which are
slightly "space invaderish." The joystick action is ^w/cegood
and won't "hang up" on those quick corners (unlike some
"Pac" games I've seen) even with "Shack" joysticks.
The scoring is well explained in the documentation which
is identical for both games. You get 15 points for each pile of
sand (dot) turned into a pearl and there is a starfish worth
500 points that randomly appears for short lengths of time
just below the Monster Cave. The catalyzers are worth 30
points, and while "catalyzed," the value for eating Sand
Monsters is 100 for the first one and then doubles for each
additional one you get before the effect wears off (you can
tell when your time is running out because your shell
"clatters" audibly). There is on-screen scoring and a "Top
Ten" roster at the end of the game where up to three initials
may be entered.
Due to the similarity of these two games I would really
recommend buying only one or the other (unless you have
the $$$... but, they are different). As to which one, it all
depends. Nibbler, due to its color set, is a better choice if you
are limited to a B/ W TV, but I found the Ms. -Maze to be a
little tighter and more of a challenge. All in all, they are both
good renditions of the arcade game and would make a nice
addition to the game shelf of anyone looking for an
enjoyable "Pac" type game.
Happy Nibbling!
