folklore is that *IX (and numerous *IX work-alikes) came from simplification of MULTICS. some of the CTSS people went to the 5th flr of 545 tech sq and MULTICS and others went to the 4th flr of 545 tech sq and the ibm cambridge science center ... where cp40/cms was done (both MULTICS and cp40/cms derivative of CTSS). science center was formed 1feb1964 ... 1982 SEAS presentation on cp40/cms http://www.garlic.com/~lynn/cp40seas1982.txt misc. past posts mentioning science center http://www.garlic.com/~lynn/subtopic.html#545tech cms (cambridge monitor system) was originally developed running stand-alone on 360/40 using 1052-7 operator's console for input/output. the same machine had special hardware added to provide virtual memory support which was used for the development of (virtual machine) cp40. when standard 30/67 with virtual memory became available, cp40 morphed into cp67 ... cms continued to run both on stand-alone 360 as well as in cp67 virtual machine. with virtual memory on 370, cp67 morphed into vm370 and cms was renamed to "conversational monitor system" ... and ability to run stand-alone was crippled.

Some recent references in this a.f.c. thread: http://www.garlic.com/~lynn/2012c.html#9 The PC industry is heading for collapse there were several projects during the 80s to adapt CMS to GUI displays ... but it was somewhat anti-thetical to the corporate terminal emulation paradigm. old post about running internal corporate adtech conference spring '82 on various aspects of the subject: http://www.garlic.com/~lynn/94.html#22 http://www.garlic.com/~lynn/96.html#4a one the presentations happened to be CMS running on MVS ... there had recently been a new corporate strategy direction that CMS would be the official interactive platform. CMS on MVS (as alternative to TSO) didn't actually help things a lot ... since a lot of the problems are in base MVS (not solely in TSO). http://www.garlic.com/~lynn/2012.html#email821027 in this post http://www.garlic.com/~lynn/2012.html#12 Who originated the phrase "user-friendly"? also has ibm jargon definition for "bad response" I even got a request from the TSO product admin if I would rewrite the MVS scheduler (attempting to address some of the MVS structural problem with providing interactive service): http://www.garlic.com/~lynn/2006b.html#email800310 other drift semi-related old email about cms/xa http://www.garlic.com/~lynn/2011b.html#email821026 http://www.garlic.com/~lynn/2011b.html#email840626 http://www.garlic.com/~lynn/2011b.html#email841003 slightly related http://www.garlic.com/~lynn/2011e.html#email870508 -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
