Hello, Is there anybody in here who has any knowledge about the MPM operating system. We just got a TELEFAX cluster controller and it has some systems connected under the MPM OS. No docs available of course as the manufacturer has made his on subset of the OS. Please could anybody provide me with an address or something where I can get more info or the full set of manuals or whatever... Thanks a lot in adbance Dries Bessels Amsterdam Holland telex 18288 SITA NL SITA AMSNTXS

in response to the cat from Amsterdam... mpm was written by digital research in monterey california... it was available only for s-100 computers, i believe... it later metamorphosed into Concurrent CP/M for the 8088s & 80286s. which later became Concurrent DOS for the same CPUs... and which later became Concurrent DOS XM and Concurrent 386 for the 8088/286, and 80386, respectively... i never use a PC without Concurrent XM, if i can avoid it. it's really nice... you can't run every dos application under it, though -- especially the memory pigs...

The only MPM system I know of was actually spelled MP/M, and was a relative of CP/M. It is a multitasking, and can be configured as a multiuser, operating system for 8080/Z-80 type machines. I have never heard of an implementation on 8086 type machines (such as the IBM-PC). It is, however, substantially similar to CCP/M (Concurrent CP/M) which DOES run on 8086 machines, including the IBM-PC. I am not sure if either MP/M or CCP/M are still available; the vendor (Digital Research Inc., of Monterey, CA) is now pushing Concurrent DOS which is a follow-on to CCP/M and which is claimed to be a significant improvement on CCP/M. I can't vouch for that; the last version I could get to run on my machine was V 5.0 and they are now up to 6.0 or 7.0 or so. But they did something to the O/S after V 5.0 which breaks on a lot of hardware ... I am not the only person who has had this experience. If you can verify that this is in fact the O/S in question you may still be able to dig up some docs from DRI or from someone else. It is barely possible that if this fails, I can find some somewhere (however I don't have them here - it's a question of whether some people I know who used to run MP/M would be willing to part with old unneeded documentation). Good luck - if that's the system it is a rather arcane and not very pretty operating system. Bruce C. Wright

I sold MP/M systems in '83, and there is still one churning away at the town office here, same Z-80 computer, same Miniscribe disk, has been run everyday since May of 1983. They are about to move up to Xenix, and would have the docs available real cheap I would think. However, as the poster pointed out, it was not a very pretty system, but robust, and has done the job. If you don't need multiuser, CP/M will be much faster. -- Louis Schmittroth, Computer Science, Athabasca University auvax!louis
