re: http://www.garlic.com/~lynn/2012e.html#13 A z/OS Redbook Corrected - just about! besides the OSF and POSIX support on MVS folklore recent tale of origin of "AIX" http://www.garlic.com/~lynn/2012e.html#2 was done for IBM by the company that had done port of AT&T unix to ibm/pc as "PC/IX" ... i.e. ROMP was originally going to be the followon to the Displaywriter ... but when that was canceled, it was redirected to the unix workstation market (as PC/RT with AIX). RS/6000 and Power were then followon to PC/RT. the above also mentioned that the people that had done the initial development for what becomes SUN workstation, had come to IBM about producing the product. There was meeting in Palo Alto that included several organizations around the company ... afterwards several organizations all claimed that they were doing something better .. and IBM declined to come out with SUN workstation. Palo Alto had been working on port of Berkeley's unix work-alike (BSD) to mainframe ... but later get redirected to port it to the PC/RT ... coming out as "AOS" (as an alternative to AIX). I had done internal advanced technology conference spring of 1982 ... one of the first since the mid-70s ... when there was lots of corporate retrenching after the failure of Future System effort .. some past posts http://www.garlic.com/~lynn/submain.html#futuresys Presentations included BSD implementation on vm/370, TSS/370 UNIX PRPQ for AT&T, and CMS running under MVS ... old post regarding the adtech conference http://www.garlic.com/~lynn/96.html#4a Palo Alto was also working with UCLA and its unix work-alike (Locus) ... and ported it to both mainframe and ps2 ... which was released as AIX/370 and AIX/386. Another unix work-alike was MACH done at CMU ... a derivative can still be found as the Apple operating system. recent tale of mainframe "C language" http://www.garlic.com/~lynn/2012d.html#64 Layer 8: NASA unplugs last mainframe There joint project between IBM and AT&T for unix on the mainframe ... purely for AT&T internal use ... it involved doing a stripped down TSS/370 (residual limited availability follow-on to TSS/360) kernel with unix higher levels layered on top. Part of the TSS/370 strategy was to provide an alternative to Amdahl's "UTS" (unix) & Amdahl processors for large number of AT&T installations. As an aside, person responsible for UTS (code named "GOLD" during development for Au or Amdahl Unix) had done port of unix to ibm mainframe at school. When he was graduating, some of us attempted unsuccesfully to get IBM to make him an offer. -- 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
