Definition: 9370

A series of IBM entry-level mainframes introduced in 1986 that use the 370 architecture. In 1990, the Enterprise System models (ES/9370) were introduced, which used the Micro Channel bus and a 386 for I/O processing. A Model 14 biprocessor system added a second 386 for DOS and OS/2 applications with a high-speed link between the 386 and 370 processors.
