COCO FRIENDS DISK MAGAZINE Issue #43

"ABOUT CFDM"
Rick Cooper

COCO FRIENDS DISK MAGAZINE is dedicated to those who
still enjoy running under RS DOS.  It will deal with
that format exclusively.

A primary goal is to keep the COCO community strong.
By providing a unique means of communication, maybe
old fires will be rekindled as you and I share our
knowledge and experiences!

The success of this effort depends on each one who
becomes a subscriber.  Everyone must contribute his/
her two cents in the form of articles, programs,
opinions, experiences, etc.  If this happens we will
all look forward to the next issue.  (Check out the
manual with your starter kit for details on how to
submit material.)  Now let's have some fun!!!  =*

AN ACTIVE COCOer
ROGELIO PEREA

NOTE: A few months ago I noticed some program
      listings and articles in Glenside's CoCo 123
      newsletter.  The author was Rogelio Perea.
      I contacted Rogelio and invited him to join
      our group.  Here's some of his letter which
      describes his CoCo activities.

----------------------------------------------------
...How did I come to write submissions to magazines?
Well, it was sort of an accident: being a frequent
visitor of Glenside's BBS, I once wrote a message
dealing with a way which worked for me to prevent
the infamous head-banging of the disk drives with
the CoCo, and Tony Podraza transcribed THAT message
into an article for the CoCo-123; needless to say
it, I liked to see my name in print, so I      =>
____________________________________________________

thought then I would take a chance into writing
something more.

Currently, I am involved in finishing up a BASIC09
series of procedures which compromise a guided tour
when servicing Color and B&W TV sets, maybe it will
see print in the -123 in a near future issue. This
project (which has been quite a big one for me) is
not the only one I have for the CoCo. I do like to
use RSDOS a lot; as a matter of fact, I am trying
my hand at animation done with STRING$ AND CHR$
within the original 32 character text screen of the
CoCo.  When this is finished, some old-timers from
the TRS-80 Model I and III era maybe will remember
a strange creature called "Critter".
                                          =>
____________________________________________________

After reading the stuff you sent me, I learned
about a "template disk". Is this available from you
or could I just send you the program (when its
finished--maybe by March) on a standard CoCo disk?
----------------------------------------------------
RICK:
Thanks for your support of the CoCo Rogelio!  I hope
we'll be seeing some of your work in CFDM soon!

GARFIELD QUOTES
RICK COOPER

A few issues back Ray Berney introduced us to a new
participatory event. It was the "fill in the caption
cloud" of a Garfield picture.  We had five Friends
who sent in entries.  Thanks for your participation!


By random drawing Herb Forger wins the box of ten
flippies....but all entries were great.  I even sent
one in myself.  Note to Herb: if you don't receive
your disks by the time you receive this issue, drop
me a postcard...I'm so forgetful sometimes!

To see the quotes just RUN "GARLOAD.BAS" on the
program side of this disk.

                                      =*

A few issues ago I raised the question, "Which is
the most popular section(s) in CFDM".  The results
were a little surprising although it appears that
all sections have strong support from certain
Friends.  The following results came from eleven
respondents.  Comments follow. The list is arranged
from most popular (top) to least popular.

The scoring went from 48 to 85 with the lower number
being a better score.
----------------------------------------------------
                    COMMENTS

Let's face it Rick, I like all parts of CFDM.

My favorites are the graphics in the ART GALLERY and
their audio counterparts - the music.

Choosing between sections is very difficult    =>
____________________________________________________

because I like them all.

Not much difference between 1 & 12. I like them all.

..may vary from issue to issue, but never drops
below an interest rating of 8.5 - some issues every-
thing is a 10. Ads are least favorite, but I never
fail to read them (picked up a fine pair of drives).

..fine job of mixing all - just in the right amounts

I would not like to see any one item deleted.

I try everything and read everything at least once.

More tips and hints per Ray Berney...       =*

Most Popular Sections By Herb
Herb Forger Sr

I don't really have a LIKE or DISLIKE about ANY of
the 12 sections of CFDM! The reason is because I
tend to "READ" CFDM as I do a book: I start at
ACTIVE COCO & end with Q & A. It's that simple!
However I do by-pass PROGRAMS on the first pass
(because I like to read about each program & then
flip the disk, & run it while the intro is still
fresh in my mind. (I am getting JUST PAST the "I
remember everything" stage in my life!). Honestly,
I went through each section of the past 3 issues &
personally don't want you (Rick) to change a thing!
(unless someone comes up with a new and better
category in the future). I'll repeat the old adage
"IF IT'S WORKING, DON'T FIX IT!"

I really would like to see more "PEEKS & POKES" =>
____________________________________________________

hints since P & P books are no longer available. And
I would like to see items such as how a CFDM friend
(un-named since I won't steal his thunder) gets 2 &
3 COLOR printouts from TW-128. Now I ALSO know how
to do that. (By the way, it ALSO NOW works on my PC
color printer too!) Thanks to my CFDM Friend: A
letter to you is forthcoming.

 I might just mention that my PC manual stated how
to accomplish the above within my word processing
program, but MISTAKENLY showed an example with
SPACES instead of COMMAS separating the ASCII codes.
If anyone has run into this problem, call or write
to me. I DID spend some research time on this item!

COCO SALE
DANN MCCONNELL

I have had to give up my CoCo and all the hardware
due to circumstances beyond my control, i.e. medical
bills etc. I would appreciate it if you could put an
ad in the next CFDM and mention it to the people at
the picnic that I have a complete system which
includes the printer also and many other things I
have picked up in the last 10 years.  I have listed
the major items below:

CoCo 3 512K      Color Monitor    FD502 DDD
DMP 106          Mouse            Joysticks
Extra ribbon     Books            2400 S/P Interface

Box of goodies that includes some TRS80 Model 2
stuff also. I am asking $400 firm for the above
system. I also have about 250 disks, some that  =>
____________________________________________________

I haven't even looked at, which I am asking $100 for
which includes the postage. But the CoCo package I
need postage paid to me whatever it takes.  I am
sure the complete system is well worth $400 and I
will not sell anything separate if at all possible.
I will try to stay in contact as much as possible
because I have made some good friends within the
CFDM community and I will always remember them and
continue to correspond with you all.

COCO SYSTEM FOR SALE
TIM NEIHOUSE

Rick,

I have been using a PC for a year now and haven't
really touched my CoCo. I would like to sell all.
If you would, could you please let all the CoCo
Friends know in CFDM?

I have a 512K CoCo3, a couple of CoCo 2s, MPI,
CGP220, Magnavox Monitor, Disto SCII, all kinds of
software, almost every issue of Rainbow, four disk
drives and other stuff that I can't think of now. I
want to sell all in one shot, but will consider
parting it out. I don't have any idea on a price at
this time, but it will be reasonable (less my
shipping cost. UPS is not cheap and I have a lot of
stuff! haha:-)                             =>
____________________________________________________

I know that I have abandoned the CoCo for the PC,
but.... I'm just glad that the CoCo is still enjoyed
by some and hope that someone will have a need for
the parts I have.  Please give anyone interested my
address.

TOOL TEXT
TERRY LARAWAY AND BILL BAKER

Welcome to SMALL GRAFX ETC.'S TOOL. Version 2.5
              ($15 plus shipping)

TOOL is - in it's present form - a CM3 file mani-
pulator plus a number of graphics utilities for the
High Resolution screen for the CoCo 3 - especially
for the HSCREEN2 sixteen color mode.

The requirements for the full use of this utility is
a Tandy Color Computer 3 with 512K upgrade, a floppy
disk drive, and a CGP color printer. Each picture
file requires four contiguous 8K blocks of physical
memory for storage. TOOL uses the first 52 blocks of
physical memory for CM3 file and HSCREEN2 manipula-
tions leaving the top 12 blocks for BASIC and system
usage. Since each screen requires four      =>
____________________________________________________

contiguous blocks (8K blocks) of physical memory
and since this utility identifies each screen with
the number of it's first block of memory, screen
slots are identified by the following numbers in
ascending order: 0,4,8,12,16,20,24,28,32,36,40,44,
and 48. In most TOOL utilities, screen slot numbers
can be input by the user using ONLY the above
numbers.

The following is a list of TOOL operators and some
descriptions: FLIP, LOAD, PRINT, MOVE, LOOK, SAVE,
ROLL, CHANGE, SCROLL, OVERLAY, CLEAR, COLOR, ZOOM,
SHRINK, and KILL.

FLIP-Flips screen from right to left, top to bottom
or inverts the screen.                      =>
____________________________________________________

PRINT-Prints multiple screens already in memory on
the CGP-220 Color Printer.

MOVE-Moves a screen from one screen slot to another.

ROLL-Sequentially rolls the palette colors.

SCROLL-Scrolls physical memory starting at block 0.

OVERLAY-Overlays one screen with selected pixels of
another screen.

Easy Start for Disk EDTASM+
William Astle

Do you do a lot of assembly language programming?
Do you get frustrated with "DOS" when loading Disk
EDTASM? Would you like an easier way to use the 80
Column screen?

It is possible. I was asking the same questions
stated above and started digging in various docu-
mentation I have and tracked down a method of caus-
ing the "DOS" program to autoexec a program.

It is quite simple. Add the following line to
DOS.BAS:

1 REMEDTASM  BIN

Note that the line must be exactly the same as  =>

stated. Note that the BIN extension may not be nec-
essary. If you have renamed the EDTASM file, you
will have to replace the EDTASM in the above line
with your filename.

Note that you must not have a space after REM.

You can write a program to set an 80 column screen
or a baud rate or anything else you want to do and
include

RUN"DOS"

as the last line in the program. If you have made
the change outlined above, EDTASM will start
without you needing to press 2 followed by the =>
____________________________________________________

filename of your EDTASM file. This will save a lot
of bother if you write a program which must be
tested in BASIC. Note that you will still have to
exit EDTASM in the same manner as before.

I hope you can put this information to good use.

GrafExpress Tutorial 05 Part I
Graphics and GE Windows

This months tutorial will begin to look at GE win-
dows. GE windows behave much the same as a screen.
They are different than screens in the sense that
they can be any size but are limited to  the size of
the  complete screen.  GE windows have two purposes.
The first is for the containment of graphics such as
circles, lines, etc. Text will wrap to the next line
when it reaches the edge of a window.    The second
purpose for windows is to act as a viewport into
spriteland.  This month will look at the  first
purpose for windows.

Begin by copying the file GE05.BAS to your GE disk.
This months demo uses the circle command to show
that windows contain graphics within thier borders.
The circle command in GE is similar to the BASIC =>
____________________________________________________

circle command in that the coordinates do not need
to be on the screen, however only the parts of the
circle located within the screen will be drawn.  The
demo will also show how to define a window, select
a window, copy the contents of one window to the
next, and clear windows.

The GE INIT command is used in line 90 to define use
of the CoCo's memory.  128K bytes will be used, the
screen resolution will be 320x200, two screens and
three windows will be allocated.

The windows are defined in line 210.  The syntax for
the window defination command is:
[SUB]WINDOW wnd# = xstart,ystart..xend,yend
                                                =>
____________________________________________________

The coordinates are used are your full screen coor-
dinates except if the optional SUB command is in-
cluded, in which case the coordinates are relative
to the window which is presently selected.  NOTE: If
you do not define the windows coordintes the de-
fault full screen is used (window #1 in this case).
Also note that you may use a shortcut instead of
typing WINDOW simply use the '&' symbol.  Unlike GE
pictures, GE windows may be redefined smaller or
larger at anytime.  One very handy feature is a win-
dows ability to remember its own foreground and back
ground colors and the last position accessed (plus
sprite features).  One thing to remember is that you
are limited to the coordinates of your current
screen when using graphics commands.  If your window
is 100x100 then max. coordinate is 100. <con't>  =*

GrafExpress Tutorial 05 Part II
Graphics and GE Windows

The window select and window clear command are used
in line 260.  The syntax for window select is:
WINDOW wnd#.  Graphics commands are always sent to
the current window.  The syntax for the clear window
command is: CLW.  Issuing this command will clear
the current window to the current background color.
This is an extremely fast way to clear a portion of
your screen.  In BASIC you must either use HPAINT,
HLINE (VERY SLOW) or use up precious HBUFF memory.

Lastly we cover the window copy command, which is
probably the most complex GE command, at least I
found it so.  Here is the syntax:
COPY sourcewnd [[FROM sourcescr] TO destwnd]
NOTE: Anything in brackets is optional.
                                                =>
____________________________________________________

Bear in mind that under GE you can have as many
screens as you have memory.  One of these screens
will be your current work screen and one will be
your display screen (the one you see).  All GE com-
mands go to the current work screen!!!  Another
point to remember is that WINDOW 1 is WINDOW 1 on
each screen with the same coordinates.

There are only three different ways you can use the
COPY command.  The first example is the simplest in
line 190 and line 270 (COPY1).  This copies window 1
of the display screen to window 1 of the work
screen.  Because window 1 is a full screen in size
this copies the complete screen, including other
windows.
The second way to use COPY is in line 250.    =>
____________________________________________________

COPY2TO3.  This copies from window 2 of the work
screen to window 3 of the work screen.
The last way to use the COPY command is not used in
the demo but an example would be: COPY2FROM1TO3.
This would copy from window 2 of screen 1 to window
3 of the work screen.

NOTE: GE windows do not save thier backgrounds.
Think of GE windows as defining your workspace.  If
you need to save the background use the PICTURE com-
mands.

PRINCIPLES - Part I
Stuart T. Wyss-Gallifent

Here are the seven principles that describe how
computers and people should work together.

I.  Actions should be reversible.

In a dialog between you and the computer, it should
provide a Cancel option to return to a previous
state.  You should be able to easily undo a wrong
choice, and be able to back up (undo) more than one
step.  Applications should offer "refresh" options
in case you need to restore a default value that
you accidentally erased.  Example:  If you press
E to Exit, and you didn't mean to, the computer
should ask "Are you sure?"  This will allow you to
answer No, and return to the program, instead of
exiting right away.                            ->
____________________________________________________

II. Preserve the Display Context to sustain
    Orientation.

Windows, titles, pop-up/pull-down menus and scrolls
should appear and behave in a way that suggests the
context in which the action takes place.  For
example, windows laying on top of each other, in a
specific order, or scroll-bars that cue the user
that there is additional information.  Under WINDOWS
you can pull up the Print Window on top of your
program, pull up the Options menu on top of the
PRINT Window, and pull up the Setup box on top of
the Options menu.  When you leave Setup, you see
Options (right underneath), and when you leave Setup
you see Print Window, and under that, is your
program, all in a logical order.                 ->
____________________________________________________

III. Don't rely on a person's memorization of steps

You shouldn't have to remember how to type commands
and what every command does.  Pull-down/Pop-Up
menus and other selection methods should offer
options from which you can choose.  Example: Instead
of "Save to Drive?" and hoping the user remembers,
you could put "Save to Drive ? (0 - 3)".  You give
the user some choices.  "Understand? (Y/N)" instead
of "Understand?"

IV. Give Immediate Feedback for EVERY action

Don't you hate it when you press a button, and
nothing happens?  Oh, the computer might be acting
on your press, but it should let you know. Part II=*

PRINCIPLES Part II
Stuart T. Wyss-Gallifent

IV. Cont'd:  The program should acknowledge each
step or action you take, using colors, emphasis,
or sound.  It should also denote what choice you
made, what cannot be chosen, and any errors that
might exist.  True Story:  On touch screens, people
feel more comfortable using a touch-screen when
things they touch either click or flash, or even
move when they touch it.  People want immediate
feedback.  Buttons that go in when you press them,
keyboards that click! screens that indicate choices
and errors.

V.  Confirm destructive actions.

Have you ever accidentally saved over a file that
already existed, because you accidentally used the->
____________________________________________________

same filename?  I have!  This principle says that if
you are about to erase or delete information, the
program should alert you, and give you a chance to
cancel the action.  Example: "DSKINI 0" and the
CoCo starts to erase your disk.  Something better
would be: "DSKINI 0" "This will erase ALL data on
drive 0.  Are you sure? (Y/N)"

VI. Common definitions enhance consistency.

Applications should use common definitions for
concepts, appearance of information, and interaction
techniques.  Common button shapes/functions,
same commands from program to program, etc.


____________________________________________________

VII. Keyboard and Mouse are interchangeable.

You should be able to use the keyboard to perform
actions that you could perform with a mouse, or
other pointing device.  You should be able to switch
between keyboard and mouse in the middle of an
operation.

** I must complement the Macintosh Operating System
for implementing MANY of these standards to a very
high degree, and Windows also to a point.  All Mac
applications look and run the same!  It is truly
amazing.  Most of the time, you feel so comfortable
with the new program, that you never open the
manual that comes with it!!! **

Program Interface Principles
Stuart T. Wyss-Gallifent

Years ago, three different companies investigated
program interfaces.  Interfaces are the ways that a
program interacts with you, the user.  Some common
interfaces are:GUI (Graphical User Interface), DOS,
Macintosh, Windows, OS/2 Warp, etc.  It is a means
of communicating with the computer.  All three teams
discovered the same seven principles that would make
programs easier to use, and less time-consuming to
learn.  This would increase productivity and the
comfort level, while decreasing retraining, and of
course, confusion.

The three companies were: IBM, Xerox, and Apple.
IBM published their findings in the form of a
* suggested * standard.  No-one HAS to use these,
but many of the * best * programs do.           ->
____________________________________________________

They are called CUA standards, or Common User Access
Standards.  They are part of a larger set of SAA
Standards.  SAA stands for Systems Application
Architecture.  The principles are based on these
ideas:

When applications and programs have a consistent
appearance, operational interface, and terminology,
you naturally develop a conceptual model for how to
use computer software.  If you encounter a new
application that presents a consistent appearance,
you transfer previously learned skills and
experience to the new application.  You accurately
can predict how the new application may behave and
can expect your skills to carry over to the new
application.                                   ->
____________________________________________________

I myself have encountered the annoyance of non-
standard interfaces.  Depending on what BBS I call
over the modem, they each have different ways to
look up files, read messages, even disconnect.
Some use G for Goodbye, or X for Exit, or B for Bye,
or /O for Outta-here.  It is annoying when you get
mixed up, and the BBS sends you an error message
because you typed the wrong command.  If the defacto
standard was G for goodbye, then I could type that
on ANY BBS I call, and I would expect to disconnect.

Do you see the reason for the standard?  In the next
article or so, each of the seven principles are
listed, described, and in many cases, examples are
given.                                          =*

*5OVRFLO - surging simulation
Keiran Kenny

    This animated simulation of surging water began
as a CoCo Max 3 experiment inspired partly by a
waterfall animation Amiga dealers were fond of show-
ing a few years back. I found my version effective
on CM3 but when I translated it to a NIB file and
loaded it into NIBLOADR the result was unsatisfac-
tory.
   Recently, I resurrected it and ran it in Stuart
Wyss-Gallifent's NIBSHOW2 - much better!
   I hope you will not mind the wing-flapping birds.
That was part of the animation experiment.
   Maybe a surging, purified sewerage outflow is not
a very romantic subject for display in our Art Gal-
lery but I hope you will also find *5SWRFAL/NIB an
effective simulation.
                                             =>

(NOTE: *5SWRFAL.NIB has been changed to SEWERFAL.NIB
 to be compatible with the new NIBSHOW.)

DAUGE.NIB
J R Waggoner

Many people have a favorite pet. It could be a bird,
dog, turtle, or even a lizard.  Well, mine is a cat
named Dauge (pronounced DAWG).  She was the runt of
the litter, and her mother refused to feed her, so I
took her in.

She only lived to be five human years old, but in
those 5 years, she gave us more happiness and love
than any other pet we ever had.

DAUGE.NIB is my rendition of her favorite pastime,
taking a nap.  CM3 was used to create this picture.

Graham Elphick Pictures
Keiran Kenny

   Pictures by Graham Elphick appeared in CFDM#22. I
always feel that his angular line compositions make
a strong statement, especially in the absence of
extraneous detail to distract from the impact of the
central theme.
   I received these examples of Graham's pictures
from Arthur Williams. Graham used LINEMASTER to put
the pictures into basic files. Most of them included
PLAY strings to sound the national anthems of the
countries depicted but I have converted them to NIB
files for the benefit of CoCo Friends.

NOTE: We include two of Graham's pictures as <g>

Michigan Coconut
Ron McCauley

My bride of 38 years, Gerry, and I are retired. We
were in real estate and property management, and
have been collecting Soc.Sec for a year now.

We live in Fenton,Mi. a pretty suburb of Flint,Mi.
(the birthplace of General Motors & the UAW). We
have 52 lakes within 8 miles. We are both natives of
the area. We raised 2 children. Kathy who is an eng-
ineer with GM in Flint, and Tim who is an urban plan
ner in Milwaukee. We have 2 grandchildren. Kevin and
Ellen.

I have been Coco-ing since 1988. There was an active
Coco club in Flint back then. I wound up the last
member and inherited the library! There is still an
active club in Lansing,Mi.(the capitol) which I =>
____________________________________________________

have been attending for 6 years.

I have and active coco3,512k with a pair of 502 disk
drives, a magnavox 515 monitor, and 2400 baud modem.
I also have a "super duper" Coco 1 going on 2 1/2!
with a color mono driver, word pac for 80 col.screen
color composite monitor, x-pad, multi pac and More!

Recently I aquired a Coco3 with 1 meg, 4in1 disto
controller, 85 meg hard drive and 2 720k drives all
mounted in a PC case. After 6 hours use the 1 meg.
upgrade system failed. I don't know if it will ever
go again! (Should have went mainstream MS-Dos!)

I have 5 printers. An NX-1000 color, a RS CGP-220
ink jet, a DMP 105, a CGP-115 plotter, and a  =>
____________________________________________________

electric typewriter with data outlet. Oh, I forgot,
also 2 TP-10's. (one from Rick!) They are handy for
printing directories!

My favorite activities are going on line to Delphi,
the internet, libraries, BBS's, etc., and printing
color prints on the CGP-220 inkjet.

I have a complete set of Rainbow, Hot Coco, CFDM,
Upgrade, 68 Micros, plus some of many other. My soft
ware collection is immenesse!

I have loved being a Coconut. It will be hard to
move on. I notice that most of you have taken the
step, however I plan to maintain my subscriptions to
the End! My wife wants a "GOOD" genealogy program.=*

UPDATE
Herb Schuler

Fourteen years ago on April 20, 1981 like many of
you I suppose, I had heart bypass surgery and had
one graft installed.  On April 20, 1995 I learned I
had out-lived that bypass and now needed the old
bypass bypassed as well as a second new graft. This
work was completed on April 24, 1995 and I arrived
home from the hospital on April 30th.  Today being
June 21 I have been recuperating some 8 weeks or so
now.  I am feeling fine. Yesterday my Doctor assured
me I was in fact feeling fine.  It's always nice to
have his assurance; after all, who am I to say how I
feel!!

I am amazed at the progress that has been made in
the last fourteen years in the Coronary Artery
Bypass Graft procedure.  The MOST amazing thing =>
____________________________________________________

to me is the difference in the anesthesiology (?)
process.  Last time the process started the night be
fore with a shot, and continued the day of surgery
with more being administered. And re-entry from
anesthesia was terrible.  The nurse kept trying to
awaken me and I wanted no part of it.  I felt lousy.
This go-around I received no shots until after I
arrived at the operating area, I guess, because I
have no recollection of receiving any anesthesia!!
I awoke the next morning as if I had just been to
sleep for the night...feeling great.  Within a few
minutes of awakening the nurse had me on the phone
with my wife.  I'll tell you, it was a fantastic
feeling.....remembering the previous experience.

The entire recuperation process seems to be    =>
____________________________________________________

going so much better also.  I feel better now than I
remember feeling after 3 or 4 months last time. I am
even playing the sax already!!

One regret I have is that because of this Claudie
and I will probably not make the picnic.  Of course
I have been looking forward to the picnic for some
months now, but the last week in April shot that.

Other than all this, everything is okay here. The
COCO still gets used some even though I now have a
486DX2-66. I've been moving a lot of material from
the COCO to the PC while recuperating. Oh yes, the
same Surgeon did both operations for me and he has
given me at LEAST twenty years this time so I'll
have to wait for the NEXT picnic to see you all!!=*

Has CFDM Peaked?
Perry Friesen

I did a little survey of THE RAINBOW and it's pop-
ularity measured by the number of pages in the
magazine.  It went from 4 pages in '81 to 300+ in
'85 and back down to 16 pages in '93.  Here is what
a graphical representation would look like:

    81 82 83 84 85 86 87 88 89 90 91 92 93

____________________________________________________

CFDM continues to put out 160K of magazine which
translates into 20 pages of HARDCOPY plus a steady
160K of programs not to mention the bonus disks.
This comes to about 16.6 megs of CoCo info (at Issue
41).
THE RAINBOW peaked in five years; CFDM is now in its
fifth year, so the question is: Has CFDM peaked?
Because the quanity of CFDM does not fluctuate, a
better gauge to see if CFDM has peaked is perhaps
the amount of submissions on THE EDITORS desk.  Yes?
 Another question is can we make it longer than THE
RAINBOW?  Another seven years?  The bottom line is:
Let's keep the pipeline flowing to Liberty, KY.

We can do it!

WHEW....LET'S GET CAUGHT UP!
RICK COOPER

I'm running way behind...due to the Picnic, I'm
behind about a week!  But it was well worth the lost
work time.  We had a wonderful time and it's hard
to believe it's come and gone.  We did manage to get
about 17 hours of tape and I hope to soon convert
that into a master tape to offer to all who might be
interested.

Per the Picnic, it was really interesting to "see"
those I have so often spoken with on the phone. When
Jim Bennett returned home (after a 15 hour drive),
he called to let me know that he had a safe trip. It
was so weird to now be able to put a face to the
voice!!  When Jim called I was at the computer with
Jeff Vavasour, Stuart Wyss, and Ray Berney, so they
managed to get in a word or two themselves.    =>
____________________________________________________


The question now is will we have another Picnic next
year.  I really don't know at this time, but if it
is at all possible, we'll give it a try.  If we do,
please don't miss it!  When the question was asked
during one of the latter presentations, I said the
next one would be in Hawaii and it would last for a
week! I believe someone called to make reservations!

A final note on the attendees...I often express to
my local friends that the CFDM membership is made up
of some of the nicest people in the world.  Meeting
our guests, many for the first time, has cemented
that feeling on my part!

Friend Rick:
     Enclosed is my check for $30 to continue my
subscription to * HARDCOPY * as I really enjoy the
extra effort that our Friend Arthur S. Hallock puts
into it.  He's forever trying new and more interest-
ing formats, fonts, and layouts.  His work transpos-
ing the pictures is to be commended!  I'm glad that
he continues to 'find' the time to do it each month.

     I've also added $12 to try out the new  PCFDM,
and hope that it will work on my PC286?  I'm still
working at getting the CoCo2 emulator to function
for me -- I'll have lots of questions for Jeff at

It was great talking to you today and hearing not
only of your new ZEBRA SYSTEM'S endeavor but also of
your proposed joint effort with Jeff Vavasour
regarding the PC CFDM without the emulator.  I'll be
looking forward to that new offer!

...On another topic, I was surprised to see that you
were able to find a spot for my attempt at your CFDM
Trivia Test in issue 39. You had thought it would be
in issue 40, but now this gives the Friends that
want to try it, some additional time to locate the
answers and reply.  Between you and I, the SMART
CFDM FRIENDS who have obtained the CFDM INDEX's
(Indices) and the COCO REGISTRYs would have   =>

PC equipment to join me in this effort.  Or/and tell
your friends about this new disk magazine.

HOW TIME FLYS
GARRY SPENCER

Dear Rick,

How time flys...anyway I see my subscription is
about to expire. You are not only a great editor
but also a good salesman.  I had always put off
getting HARDCOPY because I reasoned, I had a printer
and if I wanted to see something I could always dump
it to the printer.

HOWEVER, after seeing HARDCOPY, I'm signing up.....
This $60 money order is for another 6 issues of our
beloved CFDM...AND the next year of HARDCOPY.

Keep up the good work.
                      - Garry Spencer

RICK: Thanks for both renewals Garry..and yes if I
were a CFDM subscriber, I would certainly want a
subscription to HARDCOPY.  Art Hallock does a
marvelous job of putting it together each month and
it's fun just to have all the text and graphics at
arm's reach.

PICNIC EXCERPTS
NORM, RON, AND GERRY

I've received two letters from Picnicers since that
event (this is July 24th).  Here's some excerpts
from our friends.      - Rick

----------------------------------------------------
Well, I'm back in N. J.  I left Danville about 6:15
A.M. and got back here at 7:00 P.M. It turned out to
be about 760 miles...I lucked out in one respect --
the weather is much better.

..I have to tell you how much I enjoyed meeting you,
Donna and the girls, and your father. Thank you for
the hospitality in your home after the Picnic.  As
for the Picnic itself, it was well organized and
well worth the trip.  It was a great day with great
people! Count me in for next year! - Norm Barson =>
____________________________________________________

----------------------------------------------------
Rick and Donna,

  We enjoyed out trip to Liberty.  The whole day was
such fun, and the presentations were great!

  It was nice to see old CoCo friends and meet new
ones.

  We are glad you sponsored this affair, and would
come again.

  Thank you for inviting us to your home and CFDM
headquarters.  And for your warm hospitality.

                - Ron & Gerry McCauley       =>

RICK: And thank you Norm, Ron, and Gerry for helping
make this such a memorable occasion.  It was a great
priviledge to have you and the other friends here in
Kentucky for the Picnic!  I will cherish this for a
lifetime!!

                       - Rick

PICNIC TAPE?
RAY SMITH

Regarding last Saturday's phone-in - I went out for
the evening for a meal with my wife and friends and
when I returned about 10:40 pm our time, I thought
it would be an ideal opportunity to get through and
put in some bids.  I think I tried about 20 times
and got what I believe was the engaged tone each
time. I thought that packages 15 & 16 would probably
contain some programs suitable for conversion and I
was interested in 28 & 29 from a purely personal
viewpoint.  Perhaps next time.  Sorry I won't be
able to attend your picnic. I'd love to be there but
both distance and cost are beyond me.  If there are
going to be any formal lectures/discussions, why not
tape them for the benefit of those of us who can't
make the trip?  As long as the cost is not too
great!                                      =>
____________________________________________________

PS There is one disadvantage in receiving HARDCOPY,
and that is that it is so interesting, I tend to
devour every word. Arthur does such a professional
job in converting your disk to paper, that I often
leave it for ages before I look at the disk!!!

-----
RICK:  Thanks for your interesting letter Ray!  I'm
sorry to hear you couldn't get thru on Phone Fest
day...maybe next time.  Per a tape of the Picnic, I
had two video cameras and a VCR recording the event.
Just as soon as I can get caught up I will try to
get that tape together.  It will sell for $20 plus
$2 s/h.  I hired two ladies (at $50 each) to keep
those cameras and tape going from 8 am to about
7:30 pm., so there's plenty of material.     =>
____________________________________________________

And thanks for the HARDCOPY kudos!  Art is quite
adept at his work.

  Hi Rick

    Here's another years subscription, for what is
consistently better every month, both the disk, and
the magazine. Keep up the good work and thank you.
I hope the fest goes well.
                           Sincerely, Bob Nicholson

RICK: Thanks for your continued support Bob!  As you
know by now the Picnic was a great success and I
wish you could have been here!

By the way, let me express my thanks to the large
number who wrote or called to say Good Luck!   =*

CHURCH
Michael Gross

     My second music program is CHURCH, which loads
the old negro spiritual "There is a Balm in Gilead".
Thanks go to Graham Elphick and A. Williams for the
graphics. I hope you like spirituals as much as I
do and are patient with my learning use of MUSIC3+
because I have been hooked on transcribing a lot of
hymns and old melodies recently. My only regret is
that I didn't start sooner and therefore contribute
as a more active member of CFDM.
     Press the reset button to get out of the
program.
     I hope you all have the words to follow along
with the tune and pay close attention to their
message.

Lables,Lables
BOB NICHOLSON

    Want a good stock of disk lables? Or any kind of
lables? And absolutely free? Go down to your local
franchised hardware store and ask for their left-
over blank header tags. When retail franchises order
for example, 200 sheets of sandpaper, they get 200
price stickers and a header tag. The first header
tag describes the sandpaper, then six price tags,
the next header would be blank, then six more price
stickers, and so on, till 34 rows exist. you can see
that there would be 33 blank headers  on this one
item, and usually, they all go into the garbage.
  Next time you buy something from Ace or Tru-Value
ask if they'll save some for you. Usually they are
white or yellow, on sales they are red. Whatever
color, the price is right!                  =*

BAGATELL
TOM LEHANE

Our friend Tom Lehane of Australia recently sent
some programs for the CFDM Friends.  I'll include
his letter below. Thanks Tom for remembering us!

The first program is BAGATEL, a penny arcade game.
Simply press the right arrow key to pull back the
shooter. You can pull it back more than once. The

Dear Rick,

Many thanks for the CoCo 2 Emulator disk and your
CoCo Friends Disk Magazine, both are greatly
appreciated. I have access to a CoCo 3 so your disk
is most welcome.                              =>

Grateful that you remembered an old CoCo user from

The enclosed disk has some of my CoCo programs that
were programmed on a CoCo 2. You are more than
welcome to include them on any of your CoCo disk
magazines.  They are CoCo 2 programs but I think
they will fit the standard of your magazine.

CFDM Data Base
Roy Putlack

In CFDM #37 Harold Moenich asked for a data base for
his CFDM friends. Here is the fulfillment of his
request. I had a lot of help from QUICKPRO+II. It is
a program that writes data base programs. The files
used by the data base are:

CFDMREP .BAS - The report to printer program
SORT    .V10 - The sort program
CFDMDB  .BAS - The data base program
CFDMDB  .DAT - The data for the data base
CFDMDB  .ISI - Used by the data base
KEYCMD  .DAT - Used by report program

This data base is easy to use. The choices available
are at the bottom of each screen. Run"CFDMDB" to run
the data base. You will see a few entries       =>
____________________________________________________

made by me. You can add, delete, or edit the data
base. Run"CFDMREP" to print a hard copy. I decided
to generate a report with all the info except for
the remarks. To get this on one line and to get my
printer (a DMP 130) to print I added two lines near
the begining of CFDMREP:

POKE150,18  -  sets my baud to 2400
PRINT#-2,CHR$(27);CHR$(20); - sets printer to 17CPI

Adjust these lines if you have a different setup.

Quickpro is a memory hog. It saves the programs in
ASCII. I converted them and renumbered the lines to
condense the code a little bit. Tried to delete some
rem lines and unneeded lines but got UL errors. =>
____________________________________________________

Quickpro is slow. If you sort use a ramdisk.

Have fun Harold!

HOW ABOUT A LITTLE RAIN?
RICK COOPER

This program was revived out of necessity!  Here it
is June 24th and issue #42 is scheduled to be mailed
to the Editors.  The only problem is I need a short
program for listing in HARDCOPY...so I search back
in my box of goodies and find a program I had sent
to RAINBOW.  After a few adjustments, I can present
this little Rainmaker to the Friends!

Just RUN "RAINFALL.BAS", wait about a minute, and
you'll be enjoying a real gusher!

More on the Emulator
Stuart T. Wyss-Gallifent

I was looking back through some past issues of CFDM
and noticed several cartoons that allude to a CoCo
being "as powerful" as a 486DX, or something.

Look no further!  It can be!  This is not a joke!

It is the CoCo III Emulator, written by Jeff
Vavasour.  The program is Shareware, and you will
need to pay a $25.00 token fee to receive your
registered copy.  It is a nice touch to see your
own name on the main title screen when you first
run the program.

I have run the Emulator on both my 486DX-40 PC, and
also on my 486DX2/50 laptop.  It works well on both.
I have composed THIS ENTIRE SUBMISSION DISK      ->
____________________________________________________

on the Emulator, running under MS-DOS!  My CoCo is
PORTABLE (when I use the laptop) and FAST (50 mhz!).

If you have an MS-DOS machine, or a computer that
will run MS-DOS programs, I recommend that you get
the Emulator.  When my real CoCo finally hits rock
bottom (many years away, I hope), the Emulator will
still allow us to use our favorite machine, just in
a "different box!"  The only downside so far is
moving the files around.  To get a CoCo disk onto
the laptop, I must use the desktop PC to format a
CoCo disk, use the CoCo to copy the files onto the
disk, use the desktop to copy to files onto a 3 1/2
inch disk, then finally put the 3 1/2 disk into the
laptop, and copy the file onto the hard drive!
A lot of work, yes, but worth the effort!        ->
____________________________________________________

This could be the CoCo that Tandy never got around
to inventing!  Imagine running a fractal slide show
on the laptop, and showing it off to friends.
"Wow!  Great fractals!  What program is that?"
"Oh, the fractals were created using SFRACTAL."
"Never heard of it.  What file format?"
"NIB, of course!"
"NIB?  What kind of viewing program does that?"
"NIBSHOW 2.0, of course, by Stuart Wyss-Gallifent."
"I knew Stuart was a great school teacher, but a
 programmer as well?  Wow!"
"Yes, the CoCo is easy to program."
"What?  You mean, this isn't an IBM program?"
"No.  NIBSHOW and SFRACTAL only run on the CoCo,
 which is being emulated on this IBM!"
"WOW! I'll say it backwards.  WOW!"      etc.   =*

The Seventh Link
Bob Nicholson

   Three or four months ago, I played this game for
the first time, I'd had it for almost a year, but
hadn't played, because it's advertised as taking
"hundreds of hours to solve". I'm not wild about
adventure type games, but this is different.
   You start by creating a character, with degrees
of:strength, wisdom, dexterity, magical powers and
so on. When you have defined yourself, you enter a
world with towns to explore, woods, rivers, mountain
areas, and underground dungeons to roam through, all
the while accumulating gold, weapons, experience,
and a whole bunch of bad guys to shoot arrows at.
   The first 25 or 30 times I played I was overcome;
made a new disk and character, and played on, until
eventually I started to gain inventory, strength,
and so on. For a couple of months now, I've been =>
____________________________________________________

playing the same disk(& game) for about an hour a
day. Every day I find something new. Recently though
I seem to have reached a level that is difficult to
get past. If there are any friends who can help, I
would appreciate it. I have also sent a call for
help to Adventure Survivors.
  I now am a party of 5 differing characters, have
found 8 towns and 7 dungeons and have a large supply
of food, money and weapons and seem to be stuck.
  This is an excellant game, with good graphics and
scrolling, and it makes the player think. Rainbow
reviewed it in their July 1990 edition. A lot of the
thinking behind the game is like "Rogue" but much
much more sophisticated. Other games I enjoy?-
Photon(to level 51), Shanghai, and almost any type
of solitaire.                                =*

CONCERNING SHERLOCK.BAS
ART BOOS

Dear Rick,

    Here is an answer to Buck Carden's question in
issue 41, pg. 18 of Hardcopy, which concerns
SHERLOCK.BAS.

    SHERLOCK was written in 100% Radio Shack Disk
Extended Color Basic on a COCO III.  It does no
machine language calls.  It is well commented and
easy to modify.  It will Load, Save, and Copy in
either binary or ASCII format.

    I am presently revising SHERLOCK to include all
of it's present features, and additionally, auto
switching from RGB to CMP, user selectable data
patterns for the sector fill routine, and probably=>
____________________________________________________

of most interest, additional support for the 80
column screen on memory and disk dumps.

    This version will be donated to CFDM when ready.

    As always, I am ever ready to support my beloved
COCO community.

                      Your Friend,

LOOKING FOR YAHTZEE3

Dear Rick,

I'm returning the CoCo Registry form and here's my
money order for issue #8 with a bonus of template
disk so I can start using my submission to you in

I have one question I'd like to ask you and others
if you will permit me. I'm looking for a game called
"YAHTZEE3" from T&D Subscription Software of Holland
Michigan. They are not currently at their address
and I assume they sold out or went out of business.

I did write a letter to them but got it returned to
me as address undeliverable.

Mini Disk Question
Laura Boyce

Does anyone know where the TRS-80 Mini Disk, cat.
# 26-3129, (white case) fits into the family of
drives?  It seems to be a single sided half-height
drive with no other identifying numbers (ie. 500,
501,502). The drive controller with it has the same
number.  It works fine, but I am curious as to
whether it may be double sided or not, or if it can
be used double sided. Does anyone else have or use
this drive?

PRINTING COLOR PICTURES
Ron McCauley

Printing color pictures from the Coco3 with Radio
Shack's CGP-220 ink jet printer (or one of the other
clones- like Cannon) is a very rewarding experience!

Colorware,(marketers of Coco Max III),and Michigan's
own Joe Walker of Supersoft Inc., created CM3 format
print drivers for the CGP-220.

Us CFDM subscribers have a wonderful collection of
NIB pictures! If we just had a NIB print driver or
a NIB to CM3 convertor, those of us with inkjet
color printers could have a ball, and show off some
pretty spectacular works!

To make these prints even MORE spectacular, print
them on Hewlett Packard CX JetSeries paper.  =>
____________________________________________________

Also Terry Laraway of Small Grafx Ect. will re-
fill the ink cartridges with Brighter ink!

It seems that the great majority of pictures created
on the Coco3 are created using Coco Max III, CM3
format. So if it is not feasable to create a NIB
print driver for the CGP-220, or a NIB to CM3 conver
tor, then perhaps a collection of disk could be made
available with the pictures uncompressed in their
native CM3 format. Either way, it sure would be nice
to be able to print all those beautiful works of art

R0BERT ALLEN TURNER.

R.E. "I HAVE A H0T C0C0" - HERB F0RGER,
      ISSUE #34 of CoCo Friends Disk Magazine.

Reply: Dear CoCoFriend Herb:

 You mentioned the problem of having a hot CoCo
after you installed a 512K upgrade. This is due
mainly to the fact that sixteen RAM chips are now
drawing power when there were previously only four.
If your upgrade has normal 41256 chips, you can
reduce this power draw by replacing them with the
41C256 variety. You asked about cutting a hole out
over the transformer. This is not really a bad idea.
Personally, I operate my CoCo with the top cover
removed. This results in frequent dusting of the
circuits, but the heat is no longer a problem. If =>
____________________________________________________

you are planning on adding a fan to the CoCo, it
would probably be a good idea to get the fan first
and then cut the hole out to match the fan. Then,
mount the fan on the top of the case, oriented so
that it draws air from the CoCo, rather than having
it blow into the CoCo. Do not power the fan from the
CoCo's power supply or transformer, as this will add
additional power draw and will probably produce more
heat than if you had no fan at all. Instead, power
the fan from a plug in wall transformer. It may be
possible to replace the transformer in the CoCo with
a higher current rated transformer. The fan then
might be powered from this transformer. The follow-
ing companies sell the sort of fans that you are
looking for, so you may wish to request a catalog
from each of them and then pick out the fan that  =>

inherited Trinity from one of our past members,
Sally Wardlow (you will recall her educational
programs featured in earlier issues).  Trinity has
only useful head movement by which she can operate
a single contact to control a scrolling monitor
display. Can you imagine how much patience Trinity
must have?  So Ian worries about someday having to
replace his CoCos as he continues to use them with
his special kids.  You may contact Ian Cunningham:

TO: DICK WILLIAMS: CM8-EXTENSION
ROBERT ALLEN TURNER.

R.E.: "CM8-Extension" - Dick Williams,
       From Issue #34 of COCO FRIENDS DISK MAGAZINE.

REPLY: Dear CoCoFriend D.W.:

 I will answer your questions in reverse order
 (The last one first, etc.):
3] Yes, you should be able to install a length of
   cable in the middle of your existing CM-8 monitor
   cable. The only problem would be if there were
   one or more bad connections. That would more than
   likely cause the display to be distorted or a bit
   'fuzzy'.
2] Yes, as far as I know, all CM-8 monitor cables
   are approximately the same length.
1] I do not know if there was ever an extension   =>
____________________________________________________

   cable made for the CM-8 monitor, but I can build
   you one if you would like. You will need to
   order the following from JDR MicroDevices, 1850
   South 10TH Street, San Jose, CA 95112-4108.

When you get the parts, send them to me at: POB 396,
Double Springs, AL 35553-0396. I will then assemble
the cable and ship it back to you. Note that you can
order more than 3' of ribbon cable, if you wish. It
costs only fifteen cents per foot. Whatever length
of ribbon cable that you send will be the length of
the cable that I assemble. I will require an added
component which I will get at Radio-Shack for $.99.
I will only charge you the $.99 plus the postage to

RE: "BIOSPHERE AND DISK DRIVE" - DONALD KELLY,
     from CFDM issue #37.

Dear CoCoFriend Donald: If the "Biosphere" program
is an OS-9 Level I program, it can be fixed to
operate with the CoCo 3. OS-9 Level I, versions 1.0
and 1.1 are not CoCo 3 compatible. OS-9 Level I,
version 2.0 is CoCo 3 compatible. The problem with
the earlier versions of OS-9 LI is that the boot
routine trashes the CoCo 3 secondary vectors. This
was fixed with version 2.0. If you have an OS-9
Level I, version 2.0 program (such as PAN The Music
Maker), then you can copy track 34 of that disk to
track 34 of a backup copy of "Biosphere". That will
allow it to boot up on the CoCo 3 (assuming that the
"Biosphere" program is an OS-9 program). The only =>
____________________________________________________

problem with this technique is that it will still
cause the CoCo 3 to crash if you press RESET. So,
instead of RESET, use CTRL+ALT+RESET to exit. Below
is a simple BASIC program to copy track 34 of an
OS-9 Level I version 2.0 diskette to an OS-9 Level
I version 1.0/1.1 diskette:
10 PCLEAR1:CLEAR5000:DIM S1$(18),S2$(18)
20 CLS
30 INPUT "INSERT ANY OS-9 LEVEL I VERSION 2.0 DISK
          INTO DRIVE 0 AND PRESS [ENTER] :";A$
40 FOR S=1 TO 18:DSKI$ 0,34,S,S1$(S),S2$(S):NEXT S
50 INPUT "INSERT A BACK-UP COPY OF ANY OS-9 LEVEL I
          VERSION 1.0/1.1 DISK INTO DRIVE 0 AND IT
          WILL BE PATCHED TO COCO 3 :";A$
60 FOR S=1 TO 18:DSKO$ 0,34,S,S1$(S),S2$(S):NEXT S
70 PRINT "FUNCTION COMPLETE.":END                 =>
____________________________________________________


I hope that this is of use. It will only patch
"Biosphere" if it is an OS-9 Level I version 1.0/1.1
program. It will actually patch any OS-9 Level I
version 1.0/1.1 program to work on the CoCo 3, but
you must have an OS-9 Level I version 2.0 program so
that track 34 can be read and transferred to the
disk that you wish to make CoCo 3 compatible.
