a 32-bit mainframe computer system family announced on June 30, 1970 as successors of the System/360 , maintaining backward compatibility . The original System/370 line underwent several architectural improvements during its roughly 20-year lifetime. One very significant change was the introduction of virtual memory, which was first made generally available in 1972. IBM System/370 Model 145 uses silicon memory chips, rather than the magnetic core technology. Monolithic circuitry also is used throughout the Model 145's central processor to perform all of the system's arithmetic and logic functions.
The IBM 4300 series of computers were mid-range systems, various models of which were sold from 1979 through 1992. The systems were compatible with the System/370 architecture .
