cms had about 64kbytes of code that was the "os" simulator that allowed "os" compilers and many applications to run unmodified. the burlington mall vm370 development group was working on a much more complete coverage of os simulation ... joke about cms 64kbyte os/360 simulation was much more cost effective than mvs 8mbyte os/360 simulation. this was about the time the FS effort failed, mad rush to get products back into the 370 pipeline (having been suspended and/or killed off during the FS period) http://www.garlic.com/~lynn/submain.html#futuresys head of POK also managed to convince corporate to kill the vm370 product, shutdown burlington mall group, and transfer all the burlington mall developers to POK or otherwise MVS/XA wouldn't ship on time. Endicott eventually managed to save the vm370 product mission but had to reconstitute a development group from scratch. the shutdown of burlington was going on in extreme secret, not planning on telling the people until a few weeks before it was effective ... minimizing the number of people that would be able to escape the move to POK. however, the shutdown managed to leak a few months early ... and numerous people managed to escape ... so many going to work at DEC on VMS (very early in its development, well before first VMS release shipped) ... that somebody observed that the head of POK was one of the biggest contributors to VMS http://en.wikipedia.org/wiki/VAX The major expansion of os/360 simulation for cms disappeared in the shutdown of the burlington mall group ... and the major person responsible was one of those that went to DEC. old post with decade of vax/vms numbers sliced and diced by year, model, US/non-US ... etc: http://www.garlic.com/~lynn/2002f.html#0 vax/vms sold into much the same mid-range market against vm/4300 ... and in similar numbers ... for small order sizes (one or few machines). A big difference was large corporations ordering several hundred vm/4300s at a time for deployment out in departmental areas. A past post mentioning explosion in vm/4300 departmental machines http://www.garlic.com/~lynn/2001m.html#15 departmental servers the explosion of vm/4300 machines inside ibm was one of the reasons the internal network passed 1000 nodes in 1983 http://www.garlic.com/~lynn/subnetwork.html#internalnet -- 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
