IBM 4300

The IBM 4300 series of computers were mid-range systems when introduced, various models of which were sold from 1979 through 1992. The systems, developed in Germany, are compatible with the System/370 instruction set. They feature modest electrical and cooling requirements, and thus do not require a data center environment.

Each model number was available in various sub-models, such as the 4341 model 1 (or 4341-1) and 4341 model 2 (4341-2).

The 4331 and 4341 run the DOS/VSE operating system with FBA DASD. I/O uses virtual addresses, unlike the System/370 architecture.

4300 systems are also capable of running the VM and MVS operating systems.

The 4381-13 through 4381-24 (announced in 1987) were entry-level machines for the 370/XA architecture. They were positioned between the IBM 9370 and IBM 3090 in performance at the time of announcement.

The 4381-3, 4381-14, 4381-24 and 4381-92 are dual-CPU models. Other models included 1, 2, 11, 12, 13, 21, 22, 23, 90 and 91.
