I read an interesting article not too long ago, about Dr.
Roget; yes, the very person who compiled lists of words
that are variations of degrees of other words. Did you
know that the word "thesaurus" actually means
"treasury"? Something new, every day. Well, the good
doctor also postulated that the human eye actually
captured individual images and transmitted them to the
brain so rapidly that we perceive them as "real-time"

His paper on the subject in the early 1800s is one of the
earliest concepts that led to the development of the
motion picture industry. Furthermore, he is credited with
placing one logarithmic scale above another, creating
(wait for it) the slide rule, with which engineers
calculated (dare I say, computed) trajectories, force
required to lift mass, gravitational pull, distance, length
of burn time for propulsion engines, etc. that sent
humans into space, around and onto and off of the
Moon, and "returned them safely to the earth". (Thanks,
Jack, for that phrase.) Today, formulas are plugged into
these fast "adding machines" that we call "computers"
and the mathematical questions are answered faster
that we can say, " ", well, never mind .... they are fast,
just so.

Never did I imagine that I would be living in an era when
these computing devices would be so commonplace.
There is more computing power in our pockets than the
engineers who designed the Mercury, Gemini and
Apollo equipment had at their disposal from the most
advanced university Cray. We are truly blessed, as
anyone who has had to a math exam with a "slip-stick"
will tell you.
A somber moment, if you will indulge me, please. Take
time to remember the good times that we have had with
those of our "family" who are no longer "hitting the
keys". More so, remember those that they left behind.
Encourage them, if you have the opportunity to contact
them. It is through our ties with each other that we grow
closer. I really do look forward to our annual gathering
to share stories, learn about what you have been doing,
and most of all, laugh with you. It is no secret that I
enjoy reading, and reading Samuel Clemens in
The Glenside Color Computer Club meets the second
Thursday of each month at the Schaumburg Township
District Library at 7:00 pm. If you need a map, see our
Glenside Homepage at:
A social get-together always follows the meeting at a
nearby restaurant, lovingly called, “The Meeting After”.
I leave you with one of his best.
"For your race, in its poverty, has unquestionably one
really effective weapon -- laughter. Power, Money,
Persuasion, Supplication, Persecution -- these can lift at
a colossal humbug, -- push it a little -- crowd it a little -weaken it a little, century by century: but only Laughter
can blow it to rags and atoms at a blast. Against the
assault of Laughter nothing can stand."
As Charlie Brown would say, "Good Grief"! Here it is,
the 6th of March, and the FEST! is looming larger by
the moment. Still so much to do, too. I will not bore you
with that.
Last year, while no one missed the FEST!, some were
interestingly diverted a few moments by the need to
turn around, twice, to find the driveway. Well, there is a
back way in ... if you go past the North Avenue (IL Rte
64) entrance (eastbound), you do not have to turn
around ... just turn right (south) at the next intersection
and right, again, about 100 feet down the road.
Until next time, I bid you "Peace".

I have been wondering why nothing about LogiCall
V7.0 ever shows up on the CoCo-list over the past two
years since its release. We now give it away FREE and
still I see nothing nor do I get requests for it. We poured
months of time into it.
Years ago I had a friend who got me into Amateur
Radio. He had the highest priced receiver on the market
given to him by his parents. A few years later I sent him
a very expensive SSB transmitter and a 500-watt linier
to go with that receiver so that we could talk to each
other between here and Florida. I later asked him how
all that gear was doing. He said he wasn’t using it so he
put it all out on the curb with the trash. He hadn’t paid
for any of it so to him it had no value.

Is this what has happened to LogiCall? It is FREE so
you think it has no value? Well, Kip Koon tried it out and
he thinks otherwise. Please read the review he wrote
about LogiCall for the magazine that was to support the
2013 CoCo Coding Contest. (It never went to print.)
Maybe when you find out more about LogiCall you will
start using it. After you use it once I am sure you will
ALWAYS use it. LogiCall runs on all CoCos with or
without DriveWire and also runs on Vcc.

LogiCall Review for CoCoCoding Contest 2013
By Kip Koon, The ComputerDoc
I have been on the CoCo List for about 2 years now, gaining much knowledge about all the changes that have
taken place since I left the CoCo behind in the middle of the 1980s. When the invitation was given to everyone to
review a program entry for the CoCoCoding Contest, I thought for a little while about it, not sure if I wanted to
review any programs since they were mostly games. When I saw there was also a disk utility entry, I really wanted
to review that one, so I jumped at the chance to give back to the CoCo Community. When asked what type of
program I would like to review, I responded that I would like to review a utility program of some type. Not being sure
what utilities were left, if any. I was surprised when I was offered LogiCall! I was very glad to get that program to
Before I begin the review, I thought I would share with you the history and origin of LogiCall as it was passed to me
from Bob Swoger by way of John Mark Mobley.
History (by: Bob Swoger):
Back in the early 80's, a Hoffman Estates, IL based firm, Microsystems Engineering Corporation (MEC), won a bid
to provide NASA with a computer automated testing package using Fluke test equipment. When the project was
finished, they turned to making an integrated software package for the Digital Equipment Corporation (DEC) PDP11 mini computer series used by big business. Argonne and Sandia National Labs, Dow Chemical, Coopers &
Lybrand, Goldman Sachs, Northern Trust, Shell Oil, Sun Microsystems, Texas Instruments, Dupont, Edwards AFB,
and MOTOROLA Research were some of many worldwide users. Their user groups, Beta testers and steering
committees looked like a Who's Who of Fortune 500 companies. MEC’s product was called MASS-11. You didn’t
buy this software, you leased it. The MASS part stands for Management Administration System Software and the
11 part stands for the computer series it ran on, the DEC PDP-11. MASS-11 contained a word processor,
spreadsheet, database, DRAW application and modem package along with a disk management system. Any data
created could be seamlessly moved from one application to another. Later, MASS-11 was made to run on the DEC
Rainbow Desk Top computer. When the IBM XT, AT and DEC VAX entered the computing arena, MASS-11 was
again updated to run on those machines keystroke for keystroke, a great selling feature. Remember, hard drives
back then were only 10 Megabytes! MASS-11 was menu driven requiring only 3 keystrokes to launch and
manipulate any application. Microsystems Engineering and MASS-11 still exist to this day, but both original owners,
Hank and Everett Karels, have passed.
Hank Karels lived two doors from me. My wife went to work for MEC - so I became familiar with the MASS-11
product. It was the high-level human interface that interested me. Having at that time a $99 ZX81 computer, I felt
that if MASS-11 could call their applications using three keystrokes, I could do it on an 8 byte microcomputer using
only one keystroke. LogiCall was born. In 1984 LogiCall moved from the ZX81 to the TS2058 and Spectrum
computers, all being Sinclair machines. Using the LarKen Disk Interface LogiCall could run on either machine, even
though they didn't use the same firmware ROMs. LogiCall could tell which machine it was on and switch systems
on the fly. I sold it in the continental US and Canada. In 1995 LogiCall was released to two vendors, Frank Davis in
Mexico, Indiana and Rod Gowen in Oregon City, Oregon. Now John Mark Mobley and I have migrated LogiCall to
the CoCo. Chris Hawks jumped in many times when we hit a brick wall.
More History by John Mark Mobley
A couple of years ago, Phil Kwitkowski, a friend of Bob Swoger, wanted to give away his Timex Sinclair 2068
system, so Bob arranged a time for me to come and pick up Phil’s system. Since LogiCall ran on the Timex
Sinclair, Bob taught me how to use both the Timex Sinclair 2068 and LogiCall. Bob had plans for many years to
rewrite LogiCall to run on the CoCo, so we began working on this project. Bob would develop the code to work on
Vcc, and I would test the code on real hardware. Bob and I connected by Skype, and I could show him how the
code ran on my CoCo. Christopher Hawks helped us get a directory listing with two files per line, and helped us
with setting or detecting caps lock.

More History by Christopher Hawks
I merely supplied the technical know-how. If Bob or John Mark needed to know how to make BASIC do something
or where something was, I could supply that knowledge. (Change keyboard entry to upper/lower case, POKE
263,255 for upper, POKE 263,0 for lower. Sometimes programs run by LogiCall would change the case to lower
and LogiCall needed upper case entry to continue running.) (And I did a lot of testing.)
Christopher R. Hawks, HAWKSoft
After another phone call with Bob Swoger, I have some more historical information. The following are notes I took
of Bob’s comments from that conversation:
“The Spectrum computer has a syntax checker. A beginning programmer could not make a mistake writing a
BASIC program that would cause a Syntax Error at run time.
Here is a sample Sinclair BASIC command line to save a file.
RANDOMIZE USER 100: SAVE “filename.ext” LINE 600 <Enter> - That’s a lot of key strokes. Wouldn’t pressing
<S> save a lot of typing? That was the reasoning behind LogiCall’s creation. Necessity is the mother of invention,
Laziness is the father. Therefore LogiCall was born.
As a young engineer, I began searching for lost endings of old sayings.
“Beauty is only skin deep, but ugly is to the bone.” (Red Foxx)
“Necessity is the mother of invention, Laziness is the father. “
“There’s more than one way to skin a cat, but only one way so as the holes don’t show.”
Engineering Quotes:
“There is nothing more permanent then a temporary installation.” (Robert Loving)
“The pressure on an object applied by a soldering iron is inversely proportional to the heat of the iron.” (George
Thus endeth the history lesson. I thought that it was very interesting to find out about how LogiCall came to be
created. I’m always interested in what spurred on the ideas and beginnings of computer products both hardware
and software. Now on to my experience learning about, using and ultimately writing a review of LogiCall.
This version of LogiCall has been in the making for 18 years since it was first shown at a Glenside Color Computer
Club meeting. LogiCall is actually an ensemble of many programs. L.BAS is the main program. John Mark Mobley
wrote MOVE and FORMAT for both CoCo and DriveWire. Chris Hawks would fix any problems that arose. If it
couldn’t be found in the manual, they’d ask Chris. Function routines and a POKE to change keyboard to all caps
are but few of the many things Chris helped with. Chris would write routines for the functions that Bob needed to
replace Sinclair keywords missing in CoCo BASIC. Bob didn’t compile LogiCall into machine code because BASIC
is just the right speed to run LogiCall. Also, he wanted to allow the user to make modifications to the programs on
his own.
My Introduction to LogiCall
As soon as I downloaded LogiCall, I began to read its documentation file (Manual). I really don’t know why, but after
reading the entire Manual, I could not wrap my head around how to use LogiCall at all and understand how the
program worked. Now normally I’m very intuitive when it comes to figuring out software, but this time, I was
stumped. I could not get it to boot up on XRoar with the Becker port activated no matter what I did. I had DriveWire
4 Server running so it should have come up running but it didn’t.
So I sent out an email to all three programmers who had a hand in its creation including the original author who got
back with me with very helpful responses. Thank you guys. The original author of LogiCall for the TIMEX/Spectrum
TS2068 computer, Bob Swoger, wanted to call me to help me through understanding the program, so I gave him
my phone number and we chatted for quite a while about his background and how he came to create LogiCall. I
wish I had a recording of that conversation. Bob is a very interesting man to talk to. Since I did not record the
conversation, I will just include pertinent parts of our conversation to the best of my memory as we go through this
Before our conversation, there were so many files in the LogiCall zip file to figure out that I did not know where to
begin. So now that I have received a guided tour of LogiCall from the original Master Programmer of the Spectrum
version, I will attempt to pass on to you all the information that Bob Swoger gave to me.
First we went through the setup for Vcc.
The MultiPak Interface (MPI) must be inserted into the cartridge port slot.
The MPI Slot 4 must have the FD-502 Floppy disk controller cartridge pak installed.
The MPI Slot 3 must have the Hard Drive plus the Cloud9 RTC (Real Time Clock) installed.
The MPI Slot 2 must have the Orchestra-90 Cartridge pak installed.
The MPI Slot 1 can be left empty.
FD-502 Drive 0 must have the disk image BasicA.DSK inserted.
FD-502 Drive 1 must have the disk image BasicB.DSK inserted.
FD-502 Drive 2 must have the disk image BasicC.DSK inserted.
FD-502 Drive 3 must have the disk image BasicD.DSK inserted.
The FD-502 Configuration must have:
a. The RGB DOS must be selected.
b. Persistent Disk Images must be checked.
c. The Clock at 0xFF50-51 must be checked.
11. The HD Drive should have the NitrOS-9.vhd file inserted.
12. Under menu item “Configuration > Config > Vcc Options > CPU tab”, these options should be selected.
a. 8192KB of RAM
b. A 1.788 MHZ clock rate
c. The Hitachi HD6309 CPU
13. Under the Display tab the RGB option should be selected.
14. Allow Resize should be checked.
15. Under the Keyboard tab > Keyboard Mapping pull down menu, select Basic to allow the <F1> key to work.
The Keyboard layout of Vcc is changed from the original CoCo layout to match as much as possible the
layout of the typical IBM PC compatible keyboard of today.
16. All other settings can use their respective defaults.
Now power cycle your virtual CoCo 3 and LogiCall should load and run automatically. The first file saved to the disk
determines the disk’s name, so don’t save L.BAS (the main LogiCall program) to the floppy disk first. Instead, first
install the program with the name you wish to also name the disk.
If you are running Vcc or DwiveWire then at the Drive? prompt you can control whether or not you have floppies or
virtual floppies in your system set-up. You can turn on hard drives 0 thru 3 by entering ON. You can also turn your
floppies on by entering OFF0 thru OFF3.
The following picture is the initial boot screen.
I really like the rich blue color for the background. Bob said that long ago people had discovered that this scheme
was the most comfortable for your eyes.
LogiCall first asks what drive you wish to see. Once you enter the drive number LogiCall puts that disk’s CATalog
on the screen and next asks you for a program to run (or command to execute). More on this later. You will
immediately notice that LogiCall booted to Drive 3. Bob said that he liked coming up on Drive 3 initially so as to not
accidentally corrupt important files on Drive 0, his LogiCall install disk. After using LogiCall for a few days, I think I
am beginning to see why. Most important programs tend to like to live in Drive 0, so having LogiCall boot to Drive 3
makes sense to me. Upon booting the CoCo, the AUTOEXEC.BAS file on VHD Drive 0 executes the high speed
POKE, installs the 4 virtual floppy drives and sets the system pointer to virtual floppy Drive 3.
LogiCall itself is only 3 granules, so it can be put on just about any disk you like. Bob explained that LogiCall
(L.BAS) should be saved on each and every populated disk. Again, since the disk name is picked up from the first
file in the CATalog, don’t save L.BAS to the disk until the main program is first installed. LogiCall always comes up
listing just BASIC programs on the current drive, so if there is a Binary file or any other file type for that matter, just
press the <V> key, which stands for Verbose, and all files on the disk will be displayed. Press the <B> key to return
the Brief CATalog.
Most of the “Program? “ prompt commands also work at the “Drive?” prompt. When I first started using LogiCall, I
thought I could only use drive numbers. Not true! I can use just about all the single letter commands also. “T” is one
exception. At the “Drive?” prompt “T” calls the Tape Drive. At the “Program?” prompt “T” calls the Terminal
At the “Drive? “ prompt, to change to another drive, just press the <0>, <1>, <2>, <3> or <T> keys and the system
pointer will point to that drive and display its contents or in the case of <T> will list the programs on the tape. In fact,
all the controls for this program are only single keystrokes! One key followed by <Enter> and that function takes
place immediately! To display the programs on a cassette tape, just press <T> and the “Play Tape” prompt appears
in the middle of the screen. The program then waits for you to begin playing a program or data tape on the cassette
If the numbers 1 through 4 or 10 through 255 are entered at the “Program? ” prompt, the system pointer points to
that drive and its CATalog is displayed. The keyboard numbers 5 through 0 were used in the LogiCall for the
Sinclair long before a CoCo version was ever developed.
One of the first functions Bob showed me was the Help Screen, there are 2. The first Help screen is shown above.
You get the Help screen using <H>, <?> or <F1> and <Enter>.
I immediately saw something strange. The key <7> erases a filename. Huh? So I asked Bob, “Why? That doesn’t
make any sense.” He said that the Timex TS2058 and Spectrum computers have all the BASIC commands printed
on every single key of the keyboard and ERASE is printed on the <7> key. LogiCall is keystroke for keystroke
compatible on both the Sinclair and the CoCo as was MASS-11 on all the machines it ran on. He said it was
impossible for a beginner to miskey any command, because the Sinclair had a syntax checker that wouldn’t allow
the user to enter a bad line of code. Of course having all the keywords printed on the key caps helped the new
programmer and saved extra typing too. In fact every key on a Sinclair has five or six separate functions! I said,
“Oh, that makes a lot more sense.” So he set out to show me what every single letter command in the HELP file did
in LogiCall.
So, to rename a file on the current disk press the <5> key or <R>, and the “RENAME Old? “ prompt appears. Enter
the old filename, press <Enter> and the “New? “ prompt appears. Enter the new filename and press <Enter> to
complete the operation. (He had me rename L.BAS to L2.BAS)
At the “Program? “ prompt, pressing the <7> key or <E> will display the “ERASE? “ prompt. Entering a filename
and pressing <Enter> will immediately erase that program file from the current disk. (He had me erase L2.BAS.
Wow LogiCall was no longer in the disk. What is he doing?)
Saving LogiCall
At the Drive? or Program? prompt pressing <S> will save the LogiCall program itself to the current disk with the
filename “L.BAS”. (L.BAS reappeared in the CATalog. The disk was now back in the state it was in before we
called RENAME and ERASE. WOW)
If you press <Enter> at the “Drive?“ prompt like I accidentally do so many times, pressing <8> or <D> at the
“Program?” prompt will return the “Drive? “ prompt instead of having to execute a program just to get back to the
“Drive? “ prompt. You can also just press the <End> key in Vcc or <Q> or the <Break> key on a real CoCo to halt
the program, then just enter the “RUN” command to begin LogiCall once again to return the “Drive?“ prompt. Typing
ON or OFF3 will turn the real or virtual floppies off or on when using Vcc or DriveWire. (The disk name will not
update until you change drives.)
At the “Program? ” prompt pressing <9> or <V> displays the CATalog or directory of the current disk, so basically it
refreshes the CATalog display.
At the “Program? ” prompt, pressing the <6> key or <M> calls in the MOVE program. The Move Utility gets loaded
into BASIC’s program memory replacing LogiCall. Within the Move Utility program, you can move a single file from
one drive to another drive by entering <1> or <M>, rename a file on a disk by entering <2> or <R>, and save the
Move Utility to disk by entering <3> or <S>. To exit back to LogiCall, enter <0> or <E> and LogiCall is loaded back
into BASIC’s program memory. Here is the MOVE & RENAME Utility screen.
At the “Program?” prompt pressing <0> or <F> calls into BASIC’s program memory the FORMAT program
replacing LogiCall just like the MOVE program did. You can format a new disk by pressing <1> or <F>; to copy an
entire disk to another disk press <2> or <C>; save the FORMAT program to the current disk press <3> or <S>.
To return to LogiCall press <0> or <E> and LogiCall is reloaded back into BASIC’s program memory. The FORMAT
& COPY utility screen is shown below.
How might you break into the program to examine the code? Press <4> or <Q> and the program stops. LIST will
list the program. “RUN” will start FORMAT.BAS again.
Did you really mean to call the MOVE program instead of the FORMAT program? Press <M> and the MOVE
program is called. Press “F” and the FORMAT program is called back in.
DWMOVE and DWFORMAT are the DriveWire versions of the MOVE and FORMAT utilities. LogiCall determines
which machine it is running on and calls the proper utility to perform these tasks without the user having to do
anything different for each system on which LogiCall is running.
Added Single Letter Calls (by Bob Swoger)
“Back in the days when I started writing and using LogiCall I found that I was using mostly my terminal package and
modem to contact my favorite BBS or I was using my word processor and printer to compose documents including
newsletters and papers for work. I therefore set up <T> to call my Terminal package and <W> to call my Word
Only at the “Program?” prompt, pressing <T> will load the Terminal application launching program into the BASIC’s
program memory replacing LogiCall just as before. A picture of the terminal application display screen appears
To run a terminal application, press <1> or <R> and the terminal application will load into memory.
LogiCall defaults to loading “V-TERM Terminal Emulator”. To SAVE downloads to disk press <2>; to
save this terminal application launching program to disk press <3>. To exit V-TERM, press <Alt> and
<Q> together, or if QUIT is highlighted with a black background press <Alt> and <Enter>.
Word Processing
At the “Program? “ prompt, pressing <W> will call the Word Processing Application launching program into
memory. Its screen is shown below.
Pressing <1> will launch the Simply Better program into memory. <2> will save a document to disk and <3> saves
the Word Processing Application launching program to the current disk. The Simply Better boot screen is shown
Pressing <Enter> will boot Simply Better with its default data module, or enter the NAME.EXT of the data module to
use, or press <?> and <Enter> for a directory. A directory is shown below. You will notice the directory of drive 50 is
being shown.
Pressing <Enter> returns to the Simply Better boot screen. And finally, pressing the <Break> key aborts. Entering
RUN”L returns to LogiCall. Unfortunately I do not know the difference in the different data modules beyond what the
filenames imply. If there is ever an opportunity in the future to expand this review to include more detail, the
differences in these data modules can be explored.
Printing the CATalog
Pressing the <Z> key displays “Printing…” at the bottom of the screen letting the user know the CATalog is being
sent to the printer. Place the printout in the disk sleeve with the disk for future reference.
Adding (Creating) AUTOEXEC.BAS
Before LogiCall the user had to create his own AUTOEXEC.BAS file. LogiCall practically writes it for you. Pressing
the <A> key adds the “AUTOEXEC.BAS” file to the current disk. Typing “LIST” instead of “RUN” in the prompted
AUTOEXEC creation sequence allows the user to modify the small AUTOEXEC program. After your modifications,
type “RUN” to save the new AUTOEXEC.BAS program to the current drive.
If AUTOEXEC.BAS is on the current drive, pressing the <N> key for NEW activates the AUTOEXEC program which
among other things re-launches LogiCall as if you had just powered on your CoCo or booted Vcc.
Brief CATalog
Pressing the <B> key displays a brief CATalog. In other words, only BASIC program files are listed. This is the
default display mode of LogiCall when it first boots. Most programs written in machine code have a BASIC driver
that calls a screen file and then the machine code file. It is the BASIC driver that the user can modify to provide a
logical return to LogiCall.
Verbose CATalog
Pressing the <V> key displays a verbose CATalog. In other words, all program files are listed.
If you select a .DOC or .TXT file LogiCall will display the file on the screen without first calling a word processor.
If you select a .BIN picture file, LogiCall will display it on the screen without first calling a picture displaying utility.
Picture files can be found starting at disk 200 when using Vcc.
Second Help Screen
Now Bob went on to explain the second Help screen. It is shown below.
As you can see, many of the commands have more than one keystroke choice to activate that particular function,
giving you logical choices, and thus the name of the program was born. Cool, huh! I thought that was a very logical
name for the program. 
Pressing <Q> and <Enter> will return you to Disk Extended Color BASIC’s “OK” prompt. An interesting side note: In
the early days of Microsoft when its owner, Bill Gates, was programming the initial Color BASIC 1.0 interpretive
language ROM for Tandy, he changed the “Ready” prompt that the BASIC language had always used up to that
point in time to the now familiar “OK” prompt to save three more bytes of precious ROM space. Bill did everything
he could to reduce the ROM memory space required to store Color BASIC 1.0 in order to add as many functions as
possible thus keeping the COLOR BASIC interpreter as compact and efficient as possible. That of course is
definitely not the case today, with Microsoft’s software packages being so huge, as we all know so well.
Return to Terminal
Pressing the <Y> key will return you to the Terminal program.
LogiCall can boot NITROS-9 by first going to the NITROS-9 disk (255) and typing “DOS” at the “Program?” prompt.
Alternate Program Loading
At the “Program? “ prompt you can type in the program name with or without the extension from the disk CATalog
or you can press <Enter> at the “Program? “ prompt and the first program on the list will become highlighted, and
you can then use the arrow keys to move the highlight to any desired program. Press <Enter> again and the
program will load and execute.
STEPRATE.BAS allows you to change the head step rate of your floppy drives. When I run STEPRATE on my
particular Vcc installation it shows the following screen.
As you can see, pressing <1> changes the step rate to 30 milliseconds, <2> changes the step rate to 20
milliseconds, and finally <3> changes the step rate to 6 milliseconds. Pressing <4> saves the program to the
current disk. Pressing <Enter> exits the program and returns to LogiCall. Pretty simple, huh? 
Summary (by Bob Swoger)
Ever hear your floppy drive chatter when loading in a program? This is because Floppy Drive Controllers are
programmed for a 30 ms head step rate. The later drives could handle 6 ms or less for faster load time.
STEPRATE.BAS allows the user to change the head step rate to match the drive. The result is NO MORE DRIVE
CHATTER and faster read and write speed.
The DISKS.BAS program is considerably more complex. Think of this program as a file card box. It holds a catalog
of 40 cards (BOXes of disks - 0 thru 39) with 10 disks per box with notes on the right.
Summary (by Bob Swoger)
DISKS allows the user to peruse up to 400 program files to find their location on your now 256 sectors of your
virtual hard drive. It was the need for this program with today’s Vcc and DriveWire’s VHD both with 256 drives that
showed us at Glenside that there was a new need to locate programs. The TAPES version handles 800 tapes with
no notes.
After creating a new disk you add the information about that disk in this file so that you can find it again in the
future. Remember the old saying; “The job is not finished until the paperwork is done.” DISKS was created to help
you fulfill that need. The initial screen showing Box 0 is shown below.
Entering a two digit number goes directly to that box number. There are some special cases though. Pressing <0>,
<4>, <5>, <6>, <7>, <8> or <9> for box 0, 4, 5, 6, 7, 8 or 9 respectively is automatic, the box is immediately
displayed. Pressing <1>, <2> or <3> requires the user to press <Enter> afterwards. This is because 1, 2 or 3 is
waiting to see if you want to press yet another number to call boxes 10 to 39.
<B>ack or <R>everse or <left-arrow>(Back to previous lower box number)
<N>ext or <F>orward or <Space> or <right-arrow> (Next higher box number)
Although the menu at the bottom of the screen does not show it, <B> or <R> or <left-arrow> go to the previous
lower box number, and <N> or <F> or <Space> or <right-arrow> goes to the next higher box number. If you are at
Box 39 and press <N> or <F> or <Space> or <right-arrow>, the program will go around to the beginning of the list
and display Box 0! As you might expect, if you are displaying Box 0 and press <B> or <R> or <left-arrow>, then
Box 39 is displayed! The program does not bomb out!. Good Work Guys! You thought of everything.
As an example of how to use this program, let us imagine you want to find V-Term, the Terminal program. From
Logicall on Disk 3, press <Enter> three times. BOX 0 of DISKS is displayed, Press the <Space> bar until you see
V-TERM (in BOX 7). The note to the right says the program is on Drive 49. Press <Q> and DRIVE 3 is displayed.
Enter 49 at the Drive? Prompt and <Enter>. Press <Enter> three times and V-TERM is now running.
Now to “Do the Paperwork”. Maintaining the information in these 40 boxes is what the short menu at the bottom of
each for is for. You can Add, Delete or Move information to any slot in the 40 boxes. It is a little tricky at first but
gets easier the more you use it.
HELP Screen
<H> or <?> or <F1>
Pressing <H>, <?> or <F1> displays DISKS Help screen which is shown below.
As you can see there is sometimes more than one key that can be used to accomplish a function. Pressing <Enter>
takes you back to the Main DISKS display screen showing the current Box number.
nn (two digit box number 0 - 39) takes you to the desired box.
<A>dd or <+> (Add entry into a slot)
Pressing <A> brings up the prompt “ADD MODE – SLOT(1 – 20) ? ” and then the user enters a slot number 1
through 20 and then presses <Enter> indicating into which slot the user wishes to enter data. The DISKS program
then displays the “TITLE? ” prompt, then the user enters the title of the disk for that slot in the current box and
presses <Enter>.
<D>elete or <-> or <7> or <0> (Delete entry in a slot)
Pressing <D>, <->, <7> or <0> enters the delete mode with the prompt “DELETE MODE – SLOT(1 – 20) ? ”. The
user enters a number 1 – 20, then <Enter> and the data in that slot is deleted.
<M>ove or <6> (Move slot data from a slot in the current box to a slot in another box (or the same box)
Pressing <M> displays the prompt “MOVE FROM SLOT(1 – 20) ? ”. The user enters a slot number and presses
The prompt “DELETE FROM OLD SLOT (Y\N)” is displayed and the user responses with <Y> to delete the data in
that slot or <N> or <Enter> to leave the data unchanged.
Then the prompt “MOVE TO WHAT BOX (0 - 39)? ” is displayed. The user enters the box number for the box the
user wishes the data to be entered into and presses <Enter>. If a number is not given LogiCall assumes you want
the current box.
The prompt “MOVE INTO SLOT (1 – 20) ? ” is displayed and the user enters the slot number to receive the data
and the data is automatically entered into that slot.
<C> or <K> or <L> or <V>
Pressing <C>, <K>, <L> or <V> will print the entire database from Box 0 – Box 39.
<P> or <Z>
Pressing <P> or <Z> copies the screen to the printer. If using Vcc, printing works by activating the bit-banger port
and opening a text file for the printout to be stored. After the printout, the program returns back to the current box.
<U>pdate – Update Drive Pointer
Pressing <U> will display “Drive? ” in the middle of the screen. The user enters the desired drive number to change
to in order to save another or separate copy of the program and database file on the new desired drive. You can
also turn on hard drive drives 0 thru 3 by entering ON. You can also turn your floppies on by entering OFF0 thru
Now, last, but definitely not least, pressing <S> displays “Saving on Drive 3” which saves all of DISKS database
information and the DISKS.BAS program itself to the current drive, which was the drive I was on when I started the
DISKS.BAS program in the first place. Don’t forget to save all your data changes. If you quit DISKS.BAS without
saving, then all your changes are gone and you have to make your changes all over again!
Pressing <E> saves the entire database file and the program DISKS.BAS to the current drive and exits the DISKS
program and returns to LogiCall.
Pressing <Q> just quits the DISKS program without a save and returns to LogiCall. All changes are lost.
TAPES.BAS operates exactly the same as the DISKS.BAS program since all the controls are exactly the same.
The only difference is you store 20 tape names in the 20 slots in each box for a total of 800 tapes instead of 400
disks with notes.
This completes the review of all the commands of the LogiCall, STEPRATE, DISKS and TAPES programs. I will be
using LogiCall quite bit in all my DECB only installations, both emulators and real CoCos, as much as possible. It
really saves a lot of time! Of course I will not be able use it for NitrOS-9 since it is written in Disk Extended Color
Basic and cannot read NitrOS-9/OS-9 formatted disks. Of course maybe the LogiCall programming team might
create a NitrOS-9 version some day, but hey, this is definitely my own speculation. I do not have any knowledge of
such an undertaking at this time, but who knows…
There is so much information in LogiCall to review. Since this has to be typeset tomorrow, I must put this to bed.
Further Information about LogiCall (given to me by John Mark Mobley from YouTube.)
The link for an excellent introductory video of LogiCall by Bob Swoger himself on YouTube follows along with the
caption listed below the video. The history portion has been integrated into the beginning of this review.
This is a glance at the LogiCall operating system as part of the Vintage Computer Festival Midwest Version 6.0 and
Emergency Chicagoland Commodore Convention held on Sept. 24-25, 2011 in Lombard, IL. The computer used in
the video is a Timex/Sinclair TS-2068 computer running LogiCall. LogiCall is an Operating System (written in
Cambridge BASIC) that provides disk management and program selection from the disk catalog/directory. The
program is written by Bob Swoger of --==GATOR==-- Software Development.
Information on various computers mentioned in this review in no particular order:
For further information about the Timex/Sinclair TS-2068, access the following link.
Many thanks go to Bob Swoger, John Mark Mobley, Christopher Hawks and Aaron Wolfe for all their help without
which this review would not have been possible.
Personally, I think John Mark and Chris did a lot more than they let on in the histories they provided. I know Bob
Swoger did for sure. Writing a comprehensive software package and testing that package requires a lot of work,
not to mention converting that software package to run on other sometimes dissimilar computing platforms. In
order to create a cohesive software package like this much research, planning, coding and testing, not to mention
more research, more coding, and more testing go into a big project like this. The cycle continues until you feel you
have included everything you wanted in your creation. Once you feel it’s complete, then you allow others to do
alpha testing and beta testing until ultimately a final version of the software package is released, hoping people will
like it.
Check out this collection of programs for yourself. You just might be glad you did. I know I am. I hope this review
has given you some idea of what LogiCall, STEPRATE, DISKS and TAPES can do for you. Happy LogiCalling on
your favorite computer – The Great and Mighty Color Computer 1, 2 & 3! Qaplah! StarFleet Out. End
Transmission. 
Above is a Timex/Sinclair TS-2068 keyboard which explains the choice of key selection used in LogiCall. Note that
some keys select as many as 6 different functions.
In the BELFRY directory are many files that allow the user to modify files for LogiCall or for any other
reason you desire using the utilities in ToolShed. A partial menu of these batch calls is provided. Files
beginning with “move” move edited files from the Files directory to the virtual floppies. Files beginning with “rtrn”
return files from the virtual floppies back to the Files directory. Viewing these batch files will show you how to
create others.
