From Simple English Wikipedia, the free encyclopedia System 370, with tape drive 2401. The System/370 or S/370 was a mainframe architecture, IBM built in the 1970s. The System was mostly compatible with System/360, which IBM had built before. >Many applications coulds be re-used. The biggest change was that S/370 could handle virtual memory.

- The IBM System/370 Model 168 and Model 158 were both announced on August 2, 1972. Prior 370 systems had not "offered virtual storage capability, which was to be a hallmark of the 370 line," and some said that the 168 and 158 were the first "real 370" products. By contrast, "in 1972, the System/370 Advanced Function was released and had new Address ...
