Description
MFT was intended to serve as a stop-gap until Multiprogramming with a Variable number of Tasks (MVT), the intended "target" configuration of OS/360, became available in 1967. Early versions of MVT had many problems, so the simpler MFT continued to be used for many years. After introducing new System/370 machines with virtual memory, in 1972 MFT was developed into OS/VS1, the last system of this particular line.
