It was either CMS (a single-user UNIX-like commonly distributed with VM) or VM/IX aka AIX/370 (an IBM-flavored SysV, but almost totally unrelated to the other AIX products.)
- kjs3 10y agoI used VM/CMS quite a bit in the '80s; CMS is nothing remotely like Unix (or much of anything else outside of the IBM universe). VM/IX (nee IX/370) is not the same thing as AIX/370; IX was a joint development with ISC (who also wrote PC/IX) while AIX/370 was a joint development with Locus (who also wrote AIX for PS/2 and PC/RT). IX/370 faded away and AIX/370 evolved into AIX/ESA which allowed it to run as a guest VM. History lesson aside, since the OP specifically said he was using an Amdahl, he was almost certainly runnig UTS.
