IBM Palo Alto was also working on VM/370 for USC (Berkeley) BSD unix ... lots of unix functions directly supported by vm/370 operating system ... sort of similar to the AT&T unix being done for TSS/370 SSUP (things like unix fork, creating multiple address spaces would be done by vm/370). However before its ships ... the palo alto group got redirected to port BSD to PC/RT as AOS (as alternative to AIXV2 ... an AT&T Unix port also done by interactive, interactive had also done PC/IX for IBM/PC). IBM Palo Alto also does work with UCLA Locus turning out AIX/370 & AIX/PS2 I had internal adtech conference spring 82, week before spring SHARE http://www.garlic.com/~lynn/96.html#4a John Hartmann's Birthday Party other refs: http://www.garlic.com/~lynn/94.html#22 CP spooling & programming technology http://www.garlic.com/~lynn/2010c.html#46 Mythical computers and magazine reviews that had presentations on several of the items. Part of the issue was during the Future System period, 370 efforts were being shutdown (lack of 370 credited with giving clone processor makers, market foothold). When FS imploded, then there was mad rush to get stuff back in product pipelines. Normal development is 1-2yrs out, and adtech is 3-5yrs out (and research 5+yrs out). There was one last internal adtech conference where we presented 16-way SMP and the 801 group presented 801/risc ... and then many of the adtech groups were thrown into the development breach to churn out 370 products. The next adtech conference was spring 82. http://www.garlic.com/~lynn/submain.html#futuresys http://www.garlic.com/~lynn/subtopic.html#smp http://www.garlic.com/~lynn/subtopic.html#801 I've periodically pontificated on senior disk engineer getting talk at late 80s internal, worldwide, annual communication group confereince supposedly on 3174 performance but opened talk with comment that communication group was going to be responsible for demise of disk division. http://www.garlic.com/~lynn/subnetwork.html#terminal The disk division came up with number of products to try and address distributed computing but were constantly being vetoed by the communication group (that "owned" corporate strategic responsibility for everything that crossed the datacenter wall). As a work around, the disk division VP then started providing startup funding for non-IBM operations that would use IBM disks in distributed computing environments. He also funded MVS OpenEdition ... and the VP would periodically ask us to go by some of these startups to lend a hand and/or consult on MVS OpenEdition. posts in this thread: http://www.garlic.com/~lynn/2017d.html#75 Mainframe operating systems? http://www.garlic.com/~lynn/2017d.html#76 Mainframe operating systems? http://www.garlic.com/~lynn/2017d.html#78 Mainframe operating systems? http://www.garlic.com/~lynn/2017d.html#79 Mainframe operating systems? http://www.garlic.com/~lynn/2017d.html#80 Mainframe operating systems? -- 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
