IBSYS was the operating system of the IBM 7094 and probably the 7090 7070 7074. (36 bit word machine)
There was an early version(s) of OS that ran on the 7094. The original "production" version of OS was PCP (primary control program?). It was used on the 360/75 at Oak Ridge National Laboratory (1966-?). For more info ask Robert Rannie. There were two version of MFT -- one with multitasking and one without. The FE manual S229-3169-3 (1971July) refers to a manual "OS planning for MFT II" GC27-6939.
