Before 1990[edit]

Before 1990 IBM was putting boards into PC AT computers that had a Power processor capable of executing the IBM VM operating system. I used one on a trial basis for my employer to do development work. Sam Tomato (talk) 19:42, 13 July 2015 (UTC)[reply]

So that processor was running a System/370 emulator on which VM was running? VM runs on S/3x0 and z/Architecture, not POWER or PowerPC/Power ISA.

Or are you thinking of machines such as the Personal Computer XT/370, Personal Computer AT/370, IBM 7437 VM/SP Personal Workstation, and IPersonal/370, none of which appear to be based on POWER processors (the first two, at least, are based on re-microprogrammed Motorola 68000s plus an Intel 8087 for floating-point (modified to handle hexadecimal floating-point rather than IEEE floating point).
