When Multics was officially released as free software a couple of
years ago, there was a flurry of activity aimed at getting some sort
of emulator up and running to run it. Did anything ever come of that
or did folks just lose interest (or find out that the needed
GE/Honeywell hardware was too poorly-documented to write an emulator
of)

I hadn't checked on Multics progress in quite a while. Yesterday I
discovered that the DPS-8/M emulator at:
https://SourceForge.net/projects/dps8m/
is far enough along to boot Multics. I thought some folks on this list
might be interested in it.
Using the files from the QuickStart_MR12.6d.zip archive I managed to boot
Multics yesterday. The README file in that archive describes how to boot
the system and sign on as Repair.SysAdmin, but not much else. I'd never
touched a Multics system before, and didn't have time yesterday to get to
know the system. Does anyone know of any Multics How-Tos, especially how to
shut Multics down properly?

What I?d like to know is if any copies of GCOS-8 exist in the wild. That?s what I?d
personally really like to boot on the emulator. I used to be able configure all the
IOP?s, IOM?s, CPU?s, etc. from memory, power them up, and boot GCOS-8.

I don't know of anyone with GCOS when it has been mentioned over the

Many thanks to Harry and Charles for writing the emulator, and to the
others reviving the system.
I plan to have a 6180 panel at VCF West and an original 645 board from
the first Multics system for show and tell.
thanks

Subject: Re: Any word on the Multics revival front?
Sadly, I doubt it very much. It was still in use on emulated hardware until
relatively recently and I assume BULL was still making money from it and guarding its
assets. Thinkage still have GCOS products listed on their web site.
https://www.thinkage.ca/english/gcos/index.shtml
but sadly no longer a "B" compiler. I think that one has slipped past me...

There's at least some possible future upside to that, which is that if
they are (or recently were) still selling and supporting it, then they
probably still actually have it, vs. the huge amount of software of
historical interest that is already lost. Also, since Group BULL was
willing to make a Multics license available, that may serve as useful
precedent for getting them to offer a similar GCOS license at some
future date when they don't believe it will harm their commercial
interests.

I would too. I've always been curious about Honeywell OSes. Well, I'm
curious about any mainframe OSes I've never had contact with, which is most
of them. I currently work as an IBM z/OS operator, so I'm mostly familiar
with IBM OSes. I went to college briefly at Lamar University in Beaumont,
TX in '88-'89. Sadly I dropped out during my second semester. The computer
science department had an overworked VAX 11/750. I worked as a volunteer
operator on that system. I heard the engineering department had a Honeywell
mainframe. There was one Honeywell terminal room in the computer science
building that was used by a FORTRAN programming class. The doorway to that
terminal room was the closest I ever got to the campus's Honeywell. I don't
know what model it was, or what OS it ran. I still regret not finding out
more about it while I was there. And that has made me especially curious
about Honeywell OSes.

Multics includes a GCOS (6 I think) emulator which allows some GCOS

instruction. The GCOS emulator intercepts the MME calls with Multics
exception handler, deciphers what the call wants, does it, and continues
the GCOS program.
Several of the GCOS applications provided as part of the Multics
distribution work; such as the DN355 cross assembler. (Let's see: running a
cross assembler under a GCOS simulator running under Multics, which is
running on emulated hardware. </scratch head>).
There is a also the GCOS TSS subsystem which is an interactive programming
environment supporting several languages (Multics includes the BASIC and
FORTRAN runtimes). Sadly, there remain some emulator bugs that are causing
some failures under TSS; and lacking the source code for TSS, it is proving
to be an intractable issue.

That would almost be enough for me from the sounds of things. Too bad there are issues.
I don?t suppose there is Waterloo C? That was a painful way to try to learn C

Multics does have a C compiler ? it may have been developed at Waterloo (or Calgary?). I
just checked the pnotice and see that it is copyright Honeywell and AT&T.
It is pretty lame and the run-time library is (obviously) ancient. It includes a c
preprocessor, a curses library, make, lint, and a few unix-like commands.

If the instruction set is similar it is not really that contrived. The DN355 cross
assembler is written in L66 code. Multics just needs to emulate the system calls.
Just about the same as running MVT programs under VM or MTS on Hercules. For really weird
try running the IBM1401 emulator on Hercules on X64...

I wonder if my memory can be jogged. Sadly I no longer have the materials from the TSS
internals course I went on in Holland...
