My memory, from having a "finger" program that tried to display the foreground/active process for each tty/login/utmp entry, is that there it was possible there were multiple code bases (tho it's possible there was just one, and it mutated wildly across major versions), all called "AIX" (and as my old boss, Barry Shein (BZS) at Boston University said, they all "will remind you of Unix"), there were (at least) versions for: RT PC RS/6000 (POWER, PowerPC) PS/2 I never had access to AIX/370, but BZS got a chance to try it out in a VM on the academic computing S/390, and ISTR he said it finished compiles before you hit return. There was also a (pretty clean, ISTR) port of 4.3 BSD to the RT called "ACIS", but it might only have been available to academic sites. My memory is also that IBM had a very broad license for SVR2 and when the Open Software Foundation came together (with people who weren't AT&T or Sun), IBM was able to offer that up as a code base. gether,
