Indeed they did, but I wouldn't exactly call it Unix. Our labs use Idris
because we must, and the C alone is semi-Unix-like if you look at it
just the right way. They rewrote litterally 90% of the libraries. Truly
non-portable code!

Doug,
This looks really interesting.
1. Suggest you consider uploading to Simtel20 or similar where
we can get at it. This is assuming, as you implied, that your
work is for public domain.
2. What are implications for the follow-on Z-80 derivative chips
like HD64180 and Z-280? How portable are we here? If you can make
things work in a 64k RAM space, life ought to get easier if you can
lay hands on more RAM... Somehow sounds like an awkward fit though
until you get hardware memory management to take a lot of the load off
your code...muse,muse,muse.

MARC
Z-80 Unix?
----------------------------------------------------------------------
Date: Sun, 25 Sep 1988 08:24 MDT
From: "Frank J. Wancho" <WANCHO@SIMTEL20.ARMY.MIL>
Subject: MARC
For the record, Ed Ziemba did the principal work in developing MARC, a
Unix-like OS for the Z80, collaborating with Lauren Weinstein and Leor
Zolman (of BDS-C fame), among others. After Ed died in an unfortunate
and untimely snorkling accident, Lauren picked up the work. Toward
the end of 1982, Lauren's hard disk failed, and he had to resort to
using floppy disks to regenerate the system - a slow and painful
process.
MARC required a working CP/M BIOS to use as the device interface and
provided a combination of a V6/V7 interface, an extensively reworked
runtime BDS-C library, a version of MINCE, the EMACS-like editor
from Mark of the Unicorn, and the ability to run well-behaved CP/M
programs.
Attached to the end of this message are two messages from Lauren
submitted in November 1983 announcing the demise of MARC and the
reasons why.

Lauren Weinstein has sent me the following message regarding the

an attempt to get as much of UNIX as you can on a 8080 based system.
This message was forwarded to me as list maintainer because he was
uncertain whether it would be viewed as a commercial statement and
thus be a prohibitted use of the DDN. I find this note to be of the

A very brief status report on MARC:
Due to various technical problems, the rapidly advancing state of the
art in software and affordable hardware, and a variety of
marketing considerations, the MARC software project has been
terminated. No further work is taking place on the software, and the
MARC software package will henceforth not be sold or distributed in
any manner.
Persons with specific questions on this topic may feel free to contact
me, but the decision is irrevocable. Thanks much.

Subject: Erroneous information from hp-pcd!craig about MARC
From: lauren@rand-unix
I sincerely hope that this will be my last message on this topic.
I don't know what hp-pcd!craig has been smoking, but his information
regarding MARC is absolutely and totally wrong and confused.
There isn't any "George" at Vortex. I AM VORTEX. VORTEX IS ME. Period.
I will NOT be selling or distributing MARC in any manner.
The MARC software project has been terminated.
MARC was designed only for the 8080/Z80 processors and there
have never been any plans to distribute a MARC for the 68000 or any other
processors. In point of fact, the overwhelming percentage of software
in the MARC software package is written in a non-standard 8080 assembler
and is most decidedly NOT portable in any manner.
To be blunt, the system was not really usable as other than a toy.
Performance with floppies was miserable and could not be reasonably improved.
Even with hard disks, many operations were extremely slow. The system
could NOT make use of additional memory over 64K in any manner, and
the useful workspace for user programs ended up being only around 30K,
sometimes even less. CP/M compatibility did not function properly
for about 75% of currently tested CP/M programs.
The MARC software package is fundamentally limited by its original
design parameters, and has no future beyond hardware which
is rapidly heading into oblivion -- and, as I stated, it doesn't
work well enough even on that hardware.
There are a variety of software products from various vendors on
the market which can provide much of the MARC functionality
in a much more reasonable manner, and which won't ignore the entire
base of existing CP/M software in the process. Microshell and Software
Tools are two obvious examples of reasonable approaches to the
problem of providing such an environment on limited machines.
There are also packages which can make effective use of bank-switched
memory and provide for much faster disk access, which should help
to provide functionality for that hardware which MARC could not and cannot
provide.
MARC was a good effort but is just too fundamentally limited by the
underlying hardware base for which it was designed and written.
It is just "too much" for such hardware -- the operating system
takes up so much of the memory and disks that there just isn't
anything reasonable left for the humans! Also very important
is the fact that MARC's being written mostly in 8080 assembler
made it difficult to maintain and modify and essentially impossible
to take forward into the future in the rapidly changing micro marketplace.
You might be interested to know that of the people I've talked to about
the termination of the project, the vast majority admitted that they
were planning to try upgrade to newer hardware (usually with lots
more memory and usually running a fullblown multiprocess Unix
or real multiprocess Unix look-alike system) in the near future.
Most of the people (few as they were) who sounded the most disappointed
were those with hardware that would not reasonably run MARC in any case.
However, the bottom line is that bugs and poor performance would
require so much more code to fix properly that the remaining memory
space would be made even smaller and less useful!
I don't sell *or* distribute software with which I am not happy.
I never sold a single copy of the MARC software package because
I refused to send out buggy and limited software. It doesn't
matter whether the package was going to cost $0 or $500, I simply
refuse to distribute software with which I am dissatisfied.
I've spent a large amount of time on the project, and
I'm not happy about the final outcome -- but it's time to
face reality on this topic. It was fun trying, anyway, but I've
made my decision and it is final -- I need to get on with my life
and try to make a living!
I really have nothing more to say about this. That's all, folks.

In the early days, Whitesmiths felt they were In Charge of C
programming. Above, `rewrote 90% of the libraries' means that
the usage and function names were different as well. For example:
putfmt("The number is %i\n", i);
replaced your good old printf. After a time, they released a
compatible library, but it was likely due to outrage. I have
never in the meantime seen such a blatant example of gratuitous
incompatibility. What is surprising is that this came from
the man who cowrite _Elements of Programming Style_, P.J.
Plauger. Sad.
My memory is a bit dated on the details, corrections welcome.

I heard that Some companies discontinue Fortran compilers to CP/M

I now have Fortran Compiler 3.44 include Macro-80 that is better language
for most pd softwares that require. I am happy with it. It will cost

FYI, Cromix v11 _DOES_ run on a Z80. I worked for the local Cromemco store
here and we had it back then. As a matter of fact, I was at the VPs house
last night and he was busy connecting it via modem to his PC clone. Whipping
up his own quick and dirty XMODEM transmitter in C to Procomm 2.4.2.
Cromix/Z80 uses bank swapping--the first 64K is for the OS, other 64K banks
are used for CP/M & CDOS tasks. REAL Cromix tasks can share a single 64K
bank if they are relocatable-binary. The C compiler he has for it is pitiful..
Slow as xmas, but it works!! Three pass from C to ASM, then to OBJ (?) then
a link to .BIN (whew! usoft/borland runs a little faster now-a-days! :-)
)
Cromix v20 and up used a Z80 AND a 68000 processor; it could figure out what
you were trying to run and select the correct processor.
If anybody has any Cromemco stuff they'd like to sell (or buy!) drop me a
line and I'll have Steve get in touch w/you.

Some time ago, I saw that Plu*Perfect was taking over distribution

in the auot-install version of ZCPR for CP/M 3.0 systems.
Does this really exist? has anyone used it? What about experience with
Plu*Perfect in general?
My system is an S-100 bus "boat-anchor" with a Tarbell Z-80 ( extended
addressing) running CP/M Plus (v. 3.0) in 192K of RAM using a BIOS
that I customized for my own peculiar collection of I/O boards. I
am not deterred by some assembly code hacking or BIOS customization,
but I don't want to get stuck with an unsupported, buggy program
without documentation.
Any words of wisdom would be appreciated.

An excellent source of any NEC 8500 (8xxx) peripherals at

03264, 800/338-1839. His prices vary according to whatever
lot he's purchased recently, but he is very honest, quick,
and knowledgeable. Keep in mind NEC made several models
of RAM cartridge, so the number vary. If you tell him what
you want to plug it into and he says it works he doesn't
lie. Standard disclaimers.
Technical information on the '8500 (Starlet, etal.) is
available from the Technical Support department of NEC.
Contact Kelly Ryan at 800/632-7875. They won't sell it
to you but if you sign a confidential disclosure agreement
with NEC their recent policy was to give it to you for free.
The 8500 has a 56K TPA available when you plug in a RAM
cartridge and configure it as your A: drive (otherwise the
cartridge looks like B:). All you do is plug in the cartridge,
format it with the built-in FORMAT, and switch TPA-modes using
the built-in OPTION program, and you're up. The directory
track is stored funny so directory-munging programs don't,
otherwise it's pretty much what you'd expect.

Of course, just about anything is better than IDRIS, including CPM let
alone the after market stuff in PD as well as commercial stuff that has
been around for years.
Regarding UN*X like OSes for banked memory systems, there is also QPLUS
which is more of an OS than CPM, DOS, or ZCPR3. Not well advertised,
though. And the demo PD version is somewhat stripped down from the
commercial package.
But, then again, I am biased as I helped write a good chunk of it.

At the time (~1979), I beleive Whitesmiths was afraid of incurring
the wrath of AT&T. Copyrights and such. Perhaps they were overly
cautious, or perhaps it was a valid concern. I don't know where
I heard this, but it wasn't from Whitesmiths, so take it with a grain
of salt.

I tried to send you mail directly but it bounced from mordor - joyce.
Subject: UNIX Z80
Hi Doug, I seen you posting for the source for z80 UNIX (tm) and I am very
interested in getting a copy. I should mention that I work for AT&T Canada
I am in the National Technical Support area and can be reached at ...!attcan!
dennis or here on my 6386 at home.
I have several CP/M systems lying around here and it would be great fun to
try and get UNIX running on at least one of them. I do not have any version
7 source.
Thanks in advance

"I have never in the meantime seen such a blatant example of
gratuitous incompatibility. What is surprising is that this
came from the man who cowrite _Elements of Programming Style_,
P.J. Plauger."
This discussion has overlooked the motivation of Unix incompatibility
in Idris. Plauger and associates were scared that AT&T lawyers would
shut them down under the trade secret laws because they had access to
Unix source code before they formed Whitesmiths. The "galloping
incompatibility" was an attempt to demonstrate that Idris was not a
Unix rip-off.
This was back in the days when the same company that sold Unix would
hassle you about adding an unregistered extension phone, and the
lowest-cost Unix license was $20,000 (no cheap binaries). I'd say
their concern was justified.

I have in my hands one port of XINU (as in Doug Comer) to the Z80; that
was written in C/80 CP/M C. I have seen others. The XINU port that I
have is a bare-bones kernel (no utilities). It is a little odd to see
the results of ps -efl on an ADM-3a connected to an IMSAI, though.
The XINU port that I have was done by Ed Schramm, who lives near
Norfolk, VA. I can provide an address if needed.

ah, time to start our discussions about porting Kermit to eniac, and

I run Z80MU without an AUTOEXEC.Z80 file. I believe that I ran it that
way when I had a Z-180. But, put DIR into it and see what happens. If
you still get the BDOS error, try another copy of Z80EMU or another Z-180.
