Today in History
Posted: Thu Aug 02, 2012 10:37 pm
Most have forgotten, but today, August 2, is the 40th anniversary of
- The formal announcement of the System/370 Models 158 and 168, the first IBM mainframe systems to feature semi-conductor main memory in place of magnetic core memory, and the first mainline systems with virtual storage capabilities.
- The formal announcement of OS/VS2 Release 1, basically OS/360 MVT with virtual memory.
- The formal announcement of OS/VS1, basically OS/360 MFT with virtual memory.
- The formal announcement of VM/370, basically CP67/CMS updated for the new systems.
- I think they also formally announced the System/370 Model 145 also had virtual memory capabilities. The machine itself had been previously announced.
