Hardware Description

NEC began selling, as the Parallel ACOS series, the compact AX7300 in May 1994 and the mid-sized PX7500 in July. NEC added the PX7800 in December 1994 to round out the large and ultra-large machine range. The aim of the Parallel ACOS series was to provide high-performance, mainframes at low cost by connecting multiple single-chip CMOS processors in parallel using the ACOS architecture. Other goals were to continue support of existing software resources, enhance open product interconnectivity, and provide flexible and scalable configurability.
