I pulled a copy of the 8080-SIM.LZH file from hopf (lost the exact
hostname) and started looking through the documentation.
Interesting.. Now I'm looking for a clean ASCII set of the

Subject: Help on cp/m dianostic
Message-ID: <1991Oct23.153634.1@acad2.alaska.edu>
I am trying to write a program on the imsai 8080 that will prompt the user to
input a 4 digit hex starting address and a 4 diget ending address.
The program should then test the memory between those two addresses. To test
the memory the program should write to the location, read the value back from
the location and compare the two values to test for an error. The program must
test each location with the following 4 values: ffh, 00h, aah and 55h.
If an error is found the program should output to the crt the following info:
1. The address where the error occured.
2. The data written to the location.
3. The data read from the location.
When the ending address has been tested, the program shouild output to the crt
a statement indicating the test was complete.
Any ideas?

Fred, I think you may be right here. The original poster did not mention
the size of the disk drives and the Xerox 16/8 came with either 8" or
5.25". When equipped with the 5.25", it was alternately referred to as
the DEM-II (Disk Expansion Module). Both had one floppy and one hard
disk. Looking back on the original message, the 8" system is indicated.

I have an Amstrad 8512 and on the Dr Logo disk there is a resident
system extension file called GSX, which I have understood I can
somehow use to make my programs produce graphic output. How, I ask
and turn to the manuals, only to find:
'This topic is beyond the scope of this manual and is covered no
further',
or something to that effect. Great!
So, does anyone know how I add this to my programs? Can I use it with
Turbo Pascal? Would I have to hack a MC interface? How do I use the
routines in the GSX? What routines are there? etc., etc., etc.

Yes you can use it. I did, about 1987 when I got my PCW 8512.
You can use it from Turbo pascal, assembler, C etc as long as you can do a
BDOS call (its an RSX, so you call it just like the rest of the operating
system. Or, if you have CBASIC you get some cute bolted on keywords to do
it a bit more pleasantly.
My advice is - STEER CLEAR OF GSX !!!
It is ultra buggy. It was developed for Digital Research by anothe company,
way back when. The other company never finished it. DR released it anyhow.
They later abandoned it and no applications are available other than the
original 2 - DR Graph (which is OK when it works) or DR Draw (which has
more bugs than a nest of cockroaches and falls over all the time).
GSX is a minimal implementation of GKS (the 2-D version) as of about 1982.
It is dependant on suitable drivers: Amstrad in their infinite wisdom
provided
teeny drivers that do nothing. For example, there are no input devices - a
bit of a problem there. And, doing a filled area on the screen gives
you... an outline. No filling supported.
To be fair, you get better drivers with the 2 aforementioned DR programs.
DR had to bundle drivers because the Amstrad versions were so poor that the
DR programs couldn't run with them.
Oh, and on a 2.8 MHz (effective...) Z80, software which does lots of
floating point maths and is written in a very old version of ratfor (!)
tends to be, how shall I put this, a bit slow.
It can't selectively update the screen, either, it has to redraw the lot.
The DR programs use it for all their user interface....
If this still hasn't put you off, go ahead !!
Some of the old magazines ran articles about using GSX - however I gave
away my old collection of PCW file, 8000 Plus, PCW user etc (dating back to
87) when I moved house ... sorry .

Message-ID: <9111070105.AA05295@itd.nrl.navy.mil>
I have several Xerox 820-1 computers I want to send over to the Russian
republic for their use. They can convert their voltage to 120 volts but
the power line frequency is 50 hz. These computers have the Shugart
800 drives. According to the Shugart manual, they will run on 50 Hz
but need a different motor pulley to get the spindle speed corrected.
If we do not change the motor spindle, will the machines still work?
As I see it, if you were to format and use the disk from the beginning
on 50 hz, all you would do would be to have the density on the disk go
up 6/5 ths and the gap between the start of a track and the end would
be longer. This does not seem to be a problem.
If you put a disk that has been formatted at 60 hz and data put on at
60 hz. into a machine running on 50 hz, will the disk controller chip
deal with the 5/6 ths slower data rate?
Once over there, the users will have little need to move the disks back
to a 60 hz machine. Can we do a one time transfer?
Any experience on this rather obscure matter would be appreciated. Note
that the Xerox manual does not mention AC power specs :-<

As I understand it, and I may be wrong, your going to need the 50 Hz spindle to
make the drives work. There is more to worry about than just data rates. The
Index hole is used by both the drive *AND* the 820 to determine if the drive is
ready. I suspect that if you used 60 Hz drives at 50 Hz, you will be forever
stuck in a 'drive X not ready' fault.
You would be best off using 5.25" drives, which use DC power. On the down
side, you can store very little data on the disks. If my own memory serves, 80
Kb single sided and ~170 Kb double sided. Also note that ROM level 1.x
supports 3 single sided drives, while ROM level 2.x supports 2 single or double
sided drives.
If you need any more information on the original Xerox 820 (it was not called
the 820-1 :-) send me a note. I know much more about the 820-II, but can dig
up information on the 820.

For 240/220 volt 50Hz supply Shugart sold drives with 240v motors.
A transformer can change the voltage to 110v (dont forget the DC
power supply input voltage requires changing as well!)

Yes but at a non standard disk drive speed.

The problem is that all software cannot be read if supplyed on disks
sourced from US sources (including utilitys and the boot disk!!)

They will then not be able to transfer data on 8 inch floppys to any other
systems. They should be able to machine a new pulley and adjust the
mounting of the drive motor to allow for the different belt size.
>Any experience on this rather obscure matter would be appreciated. Note

Please email if you require further assistance, I have the Shugart manuals.
I can offer free to a good home two new 110v motors, 60hz pulleys and belts.

Subject: Abandonment of Digital Research's Copyright ?
Message-ID: <k0q8Jva@quack.sac.ca.us>
The big question: Has Digital Research abandoned their
copyright on CP/M?
When I wrote upm, I was irked a bit that I couldn't pass
around BDOS and CCP with it. But now I wonder...
Is anyone still distributing CP/M under a license from DR?
Has DR done any copyright enforcing on CP/M lately?
Basically, does DR still make money off CP/M?
If the answer to all these is 'no', can that be considered
proof of copyright abandonment? Can we therefore stop passing
it around under the table and put it on an ftp site somewhere?

Subject: Length of PUBLIC symbols in M80
Message-ID: <9111151251.AA19846@gauss.math.purdue.edu>
In the Microsoft REL format, symbols can have length 7, since 3 bits in
the bitstream are allocated for the length. I have several slightly
different versions of M80. Some seem to chop all symbol names, PUBLIC
and undeclared, down to 6 bytes. Others go to 7 bytes internally, but
when writing the REL file, chop it down to 6. I have none that actually
write 7 byte symbols to the REL file.
1) Is there some reason for this? Some constraint that I'm not aware of?
2) If not, are there some patches for M80 to enable 7 byte PUBLIC
symbols?

Your best bet is 22DISK. There are a number of others, including
UNIFORM and Media-Master. Be careful! Don't spend big bux before
you know for sure that the MS-DOS program can do the format you
are interested in. Single density could be a problem. So also
could diskettes written on hardware that doesn't use one of the
readily available FDC chips. I've heard that some of the Apple
and Commodore written diskettes won't work with these programs.
What CP/M format are you interested in reading?

Check the SIG/M volumes for a file called CRTTOOLS.LBR
It contains BDS-C source code for a number of the smaller Unix-like utils.

I've managed to get one working "fairly well", but we really need to
transfer all the files to MS DOS disks.
Do you know of an easy way to do this? I know we can do it with a
telecom pgm and the RS232 port, but I don't have a telecom program on
the TRS80.
Do you know of a program (in basic since that's the only language they
have available) that will let me transfer files from the TRS80 to a

One of the big-gun systems for television weather graphics runs under
CP/M to this day. Systems that are considered obsolete by computer
people are often used on a daily basis by people in other fields who
find them perfectly functional. No, the graphics are not processed by
a Z80 (in case you were wondering).

No. David McGlone recently signed an agreement with DRI to distribute

Why not distribute a PD updated version? ZCMD and the earlier ZCPR
versions of CCP are in the public domain. I assume you aren't selling
your work, just distributing it. Z80DOS can replace BDOS.

DRI is currently selling a *lot* of copies of CP/M v3.1 release 14 which has been licensed by Amstrad Corp. for use in their hugely and implausibly succesful Amstrad PCW range. There are over 2 million of these machines in Europe - more are being sold all the time, several new models were announced a couple of months ago.
So yes, DRI are still making money out of CP/M. And to judge by the fierce license terms visible through
he shrink-wrap, they intend to enforce their copyright. :)
And no, they gave out doing bug fixes several millenia ago :( :(

If it is still there my cp-emulate was on sipb.mit.edu in pub/druid. It is
not completely finished but it does mostly work. It emulates the Z80
processor and traps CP/M calls for handling by Unix system calls. Let me
know if you make any improvements to it. I haven't had time to work on it
much lately and anyway I have picked up 3 CP/M systems since starting it so
I don't have quite as much of an incentive.

Sorry to have to break the bad news :-) ...
The only programs I know of that use GSX (on a Rainbow 100, right?) are
Lotus 1-2-3 and Lotus Symphony for CP/M. 1-2-3 is version 1.3, and Symphony
is at version 1.0 ....Symphony for MS-DOS is ver.1.1, and simply uses its
own low-level interface to the Graphics card. I believe DEC released at one
time preliminary versions of graphics software, but it never got off the ground,
even in the CP/M world. Note that one can still obtain information on the API
(programming interface) used by GSX programs, but that information on the
actual low-level interface to the graphics card is still classed as
'proprietary' by DEC, and is thus unavailable. They will, however, supply
examples of assembly interfacing in MS-DOS !! (Go figure...)

One method would be to install a copy of BYE on the Osborne, marry the

FAULTS IN Z80DOS DATESTAMPING UTILITIES
I should be grateful for any help with date/time stamping
utilities for Z80DOS. I use a z-system for the TRS-80 Model 4
(without a realtime clock) which I did not put together myself
and which includes Z80DOS 2.4. I downloaded Z80DOS10.LBR,
SDATE10.LBR and Z8D-UTL1.LBR but could not make the utilities
work together:
Initdir sets up an additional dummy directory entry for every
three existing entries, into which the datestamp is put.
With Datereg installed, I could get SDATE10 to set the date of
the disk volume, and TIME would display the date correctly.
If I set the date with TIME, however, and then read it back, I
got a garbled result.
SAVESTMP saved the datestamp in a position within the dummy
directory entry which was different from that where SDATE10 put
it.
Z80DOS appears to datestamp files, as they are accessed, with the
date set by SDATE10, but neither the TDIR-CPM nor the TDIR-Z3
utilities would display the dates in the directory; instead, the
computer hung.
I could not get any of the aliases in MODDATE to work.
Has anyone any suggestions on how to get these utilities to work
correctly? Is there a different set of utilities for Z80DOS 2.4?
If so, where can I get them from?

I have a DECmate II with 10mb hard...unhappely I do not have use for this
system and 'cause the case of mate is quite fitting for my AT286 project
I'm only interested using the Digital's terminal VR 201-C for something,
but currently I know nothing about the ('video') connector between the

Subject: Need pinout for HP keyboard
Message-ID: <1991Nov24.025759.1999@cavebbs.gen.nz>
I wonder if anybody can supply me with any pinout info for this
Hewlett-Packard keyboard.
Its product number is C1405A #ABA, and it seems to be made for
a PC rather than for a terminal, since it doesn't have the
user/system/menu keys that HP terminals have.
Why? Well, I want to replace the keyboard on my Amstrad PCW,
and somebody gave me this one.
I realise this might turn out to involve so much work as to
make it not worth bothering, but I can't see any harm in
plugging it in to see what happens. The keyboard I am replacing
operates on 5v dc, as does the HP keyboard, so I don't think I
am going to damage anything, provided I get the pinout right.
Any other technical info that might help in this situation
would also be welcome.
Replies by email please, to the addresses below. I can post a
summary, if anybody else is interested.

Is it possible to get QTERM 4.3 running on a Morrow Micro-Decision 11?
I applied the 4.2 patch, but the "escape to local key" seem to be offset
improperly, ie the program reports the "escape to local key" as another
key instead of escape-\. No key combination brings you back to local
mode, however.

Which ones? What I really need is some sort of test suite. I started on
one to test cp-emulate but the test suite seems like more work than the
emulator itself. The BIOS is fudged so I'm not suprised that it isn't
bullet proof but I would be interested to know where you found shortfalls.
As for self-modifying code as long as it keeps away from the BDOS and BIOS
it should work fine.

As long as I get feedback I will continue to work on cp-emulate as time
permits. Although I have no specific need any more for a CP/M emulator I
still have the interest. In fact I think I'll pull it out and have another
look at it tonight.

Subject: TeleVideo 803, QTERM, and termcap
Message-ID: <1991Nov24.202810.3810@mel.dit.csiro.au>
I have a TS803 running all by itself and doing fine. I have used David G's
QTERM a number of times quite successfully, primarily for download (SIMTEL).
My wife "owns" this machine, and has just discovered my Unix box. I connected
the two permanently, showed her how to use QTERM, and off she went (vi and
rogue in particular). Now I find that there appears to be a termcap problem.
I have played around with it some. I find the tvi925 entry (as modified for
my actual 925) to work nearly perfectly. It has one problem, for which I'm
looking around now. Upon a clear-screen/home, in 'vi' or rogue, it eats
some characters from the first line. Appears to be the second through
about fifth or so. I've tried various padding, eliminating the 'ho' entry
(leaving it to use 'cm' with padding), etc. but to no avail.
I have the hardware manual for the 925, but that hasn't helped. I don't
have the manual for the 803, at least not a hardware one, listing the
cursor-control sequences.
Is this caused by QTERM? Anyone have either a manual or a working termcap
entry for this combination? All I'd need from the manual is the control
sequence listing (although DIP-switch description wouldn't hurt!).
Thanks much. My wife thanks you too. Sigh--another Rogue Monster. Just
after my 8 year old daughter got started and I had to add a VT100 for her!

For several months I have been threatening to distribute
UZI280, my hopped-up version if UZI (Unix Z80 Implementation)
for the Z280 processor. Unfortunately, Simtel20 sppears to
be unable to receive anymore uploads, and I have not had a chance
to do as much documentation and "packaging" as I would like.
BUT, if you would like a copy, sent me mail, and I could FTP it
to you. I have already done this for a couple of people.
You would get all the UZI280 stuff, plus my CP/M 3.0 BIOS
for the Z280, plus tons of other goodies. Send mail for more information.

How does one 'get' files from simtel20?? I finally figured out thier unique

Am I overlooking the obvious?

I'm using TeleVideo TS-803 which uses GSX (And not rainbow).
In the graphic demo program I've got with the computer they said that
they are more programs from DRI which use GSX..

Hi
Try this:
1 Turn the vt100 emulation OFF
2 at your UN*X system do the following:
unsetenv TERM
setenv TERM tvi950
I hope it'll work..

Subject: Xerox 820/II
I am going to become an owner of a Xerox 820/II in the very near future, and
I have a question for the 820 owners out there. What type of printers do these
units support? I presently have a Panasonic KX-P1090 (Centronics interface)
with an installed serial interface. Will the unit work with that type of
printer, or does it require a centronics interface?
I recall that a special cable was required when I transferred some software to
the system I am getting for its original owner several years ago. This cable
connected to a double row male set of pins at the rear of one of the boards. I
would assume that is a centronics parallel cable connector. I did not get into
the printer installation at the time. And the owner bought a printer, but has
never connected the computer to a printer.
Can you address a serial port for the printer, as my Kaypro does, or is it a
strictly parallel connection. If the cable needed (if only parallel), is it
still available or do I have to modify a cable such as the ibm (BAH HUMBUG)
to go to the centronics input on the printer. Basicly I would build an
adaptor from the double row connector to the 25 pin D connector.
Any assistance will be greatly appreciated.

excerpted from the readme file:
README - readme file for Z80/Z280 disassembler
----------------------------------------------
This package contains an intelligent Z80/Z280 (compile-time selectable)
disassembler for CP/M .COM files. It is derived from an excellent dumb
disassembler by Luc Rooijakkers <lwj@cs.kun.nl>.
The disassembler has the following features:
produces output capable of being assembled.
detects code sequences by tracing jump targets
specific addresses may be forced to be either code or data
a starting address may be specified
an ending address may be specified
disassembly may be started at any byte offset into the file
it is very,very fast.
a Usage message is issued if no arguments are specified.
