With the recent discussions about old GE systems and where GECOS came from, I started to wonder if anyone still used Multics on any systems. Are there any sites out there that run Multics?? Is there any source code available for it (since I'm asking). I presume it would have been written in something like FORTRAN. We hypothesized that maybe Bell Labs or MIT might be. Well, just curious.

Well, we have a 5 processor Multics system which we use as a general purpose mainframe. We also do a lot of Multics maintenance and development work for Honeywell (I guess it must be Honeywell Bull these days). Multics itself was written in PL/I except for those bits written in ALM, Multics' assembly language. The funny thing about Multics is that although it is 20 years old, there are oodles of features present on Multics that you won't find anywhere else. Even if you do find them elsewhere, they often aren't as good. I remember being particularly impressed by the whole organization of the system. With all operating systems, one asks one's self "at what level do things stop looking clean and get hacky"? With Multics, it's clean all the way down to the hardware. Incidentally, anyone thinking of writing an emacs should look at Multics emacs. It's the best that I've ever seen (if you are on the net Bernie Greenberg, thankyou). If you have specific questions, feel free to mail them to me, and I'll do my best to answer them, although it's been a little while since I used Multics to write any programs.

Also as someone else said, there are lots of neat features available in Multics. In addition to B2 level security there are many tools to help developers. If you want more details, let me know and I'll dust off my manuals. The main problem with MULTICS appears to be two-fold. 1) It is pretty much tied to the hardware and 2) Honeywell couldn't market its way out of a paper bag. -Ray P.S.

Some Honeywell-Bull systems still run Multics or GCOS. Where they are I
don't know for sure, but my last job was working on Honeywell terminal
emulators and I know some of our customers were using them.

Honeywell Bull still has about 50 Multics customers, and a total of about 70 systems (there are a few internal systems, and some customers have more than one). MIT discontinued its Multics service last winter. As far as I know, Bell Labs NEVER had a Multics system of their own (they got out of the project pretty early). There are still five Multics systems at the Pentagon, several each at Ford Motor Company and Electronic Data Systems (the computer subsidiary of GM, which also runs GM's internal computer systems), and about 40 systems in Europe (mostly in France). Officially, Multics development has been capped. However, there is still a small group in Honeywell Bull doing support for the existing customers. ("Small" is relative, since there's never been more than about 120 people in the Honeywell Multics development organization.) There's also a group at the University of Calgary's Advanced Computing Technology Centre doing contract work (Honeywell committed to this before Multics was capped). About 95% of the source code of Multics is in PL/I. A Multics system comes with full source code. I don't know of any other way to get a significant portion of it. I'm not sure why you'd want it, either. Not that it's bad, but what makes Multics so good is not the actual code, but the design. The code is not very portable, either; there's lots of implementation-dependent code and specialized Multics extensions, and there aren't many other full PL/I compilers out there, anyway.

Our two-processor L68/80 Multics is over 13 years old now, but stuck at release MR10.2 forever. Honeywell Bull dropped plans to build new faster hardware to support Multics, and was involved with the University of Calgary in investigating moving key systems software to Unix, as a migration path.

Is there anything one should be aware of that isn't presented in the

just a gnit to pick ... Multics PL/I wasn't full PL/I, either IBM or ANSI. Effectively, Multics defined the compileable subset of PL/I. This is responsible for the success (such as it is) of PL/I outside IBM.

Some of my info maybe a bit out of date since I left EDS over a year ago... At the time I left EDS, they had 3 Multics systems located in Detroit. EDS inherited them from GM. They were all medium to large sized systems running GM applications. As an aside, EDS also had 2 simular mainframes running the DTSS operating system. (DTSS Inc. has nothing to do with Honeywell). Managing the DTSS systems was my job. The university I attended, Oakland University in Rochester MI, has a small Multics system which they still use. I still have an active Multics ID at Oakland University; I login to see what's new now and then. Ford Motor in Dearborn MI also has 3 Multics systems. Other Multics sites that I've heard about include the University of Maryland, University of Texas, a few sites in France, and Honeywell's central Multics system called "System M". Multics is based on a 36-bit architecture. Also, Multics requires some special hardware to be added to Honeywell's computers in order to provide that top of the line security. This hardware is called an "Appending Unit". DTSS and GECOS runs on Honeywell's computers without an Appending Unit. I'd be glad to (try to) answer any questions I can about Multics or DTSS. car. -- Christopher A.

I don't recall how much the book talks about details of the file system implementation, but it was extensively revised in the early 70's. Additionally, at the time the book was written, the ring security facility was implemented primarily in software (resulting in many unavoidable security holes), and it was later moved into the hardware; all the stuff in the book about the gatekeeper routine is obsolete. Most of the rest of the book is still pretty accurate. The dynamic linker and the the memory mapped file system haven't changed much.

The language Multics was originally implemented in was a PL/I subset (called EPL), but a full ANSI PL/I compiler was later written, around 1968 or 1969.

This has been discussed in arch a bit, and I have to feel that if someone were going to market an o/s which is already B2 security certified they would buy the Multics rights and put it on the Intel 386. Not to get into a CPU war, but the 386 has just the rings of protection in hardware needed to implement Multics. When I first saw the chip spec I thought of Multics. Being able to do the memory mapped file i/o in hardware via segments is certainly not hard to take, either.

Last time I used Multics and PL/1 was maybe '82 or so, but I do seem to recall that Multics PL/1 still was a "subset" of the full ANSI standard at that time (and I don't suspect they've made much change since). Digging out my old Multics PL/1 manual doesn't give much enlightenment, though. Page 1, section 1, INTRODUCTION: "Multics PL/1 is closely related to ANSI PL/1.
