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.
