IBM 4300 series
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. They featured modest electrical and cooling requirements, and thus did 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 4381-21 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 and 4381-24 were dual-CPU models.
