of course there was also some amount of rivalry between the 5th flr (multics) and 4th flr (cp/67). they (also) had a lot of very security oriented customers. recent reference to IBM research report "Thirty Years Later: Lessons from the Multics Security Evaluation": http://www.garlic.com/~lynn/2013h.html#35 Some Things Never Die can now be found here http://www.acsac.org/2002/papers/classic-multics.pdf original evaluation: http://csrc.nist.gov/publications/history/karg74.pdf one of the points was the Multics was implemented in PLI and lacked the common vulnerabilities that are epidemic in C-language based software. http://en.wikipedia.org/wiki/Multics specifically related to exploits in networking ... the original mainframe tcp/ip product had been implemented in vs/pascal ... and also had none of the common vulnerabilities and exploits that are epidemic in C-language based implementations. part of the rivalry was number of sites (list of all Multics installations) http://www.multicians.org/sites.html one of my hobbies was production systems for internal datacenters ... first with cp/67 and then moved to vm370 with csc/vm. It wasn't fair to compare numbers with actual vm370 customers or even total internal vm370 customers ... so the comparison was just the number of csc/vm installations with total Multics customers (with peak csc/vm internal installations possibly 50% larger than total Multics customers). One of Multics premier sites was AFDS (#71 on above list). so it was *fun* when AFDS was looking at 210 vm370 systems ... old email posted in multics discussion group http://www.garlic.com/~lynn/2001m.html#email790404 above mentions that they were original looking for 20 ... but further explanation in this post has it increasing to 210 http://www.garlic.com/~lynn/2001m.html#15 departmental servers -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
