Some of my info maybe a bit out of date since I left EDS over a year ago...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.
