     You're confusing version numbers with model names:

AIX/6000 ran on RS6000 hardware
AIX/2    ran on the PS/2 (which is a peecee with a slightly different
          bus, aka MicroChannel architecture)
AIX/370  ran on the 370 mainframe (as a guest on VM)
AIX/ESA  ran on the 370XA or 390 series mainframe (native mode or guest)
