Whatever happened to IBM 360 and OS/360 ?
circa 1970, virtual memory hardware was added and it became the System/370, and the various flavors of OS/360 became OS/VS1, OS/VS2, which became MVS, which spawned an endless train of eTLA's leading up to today's z/OS. Amazingly enough, many programs written in the 1960s for the MFT and MVT flavors of OS/360 still run on today's z/OS without any modifications or even recompilation.
