Software Description

NEC announced the ACOS-2/XP (which stood for “extended processor”) operating system designed for compact mainframes in May 1994 and began shipping the operating system in July. ACOS-2/XP ran on the compact AX7300 and AX7300V models of the Parallel ACOS mainframe series, which packed all the calculation processing functions into one NOAH chip, a CMOS processor. To address the rise in end-user computing, driven by personal computers and workstations, as well as centralized processing of mission-critical operations, ACOS-2/XP provided a number of software functions making it easier for end-user departments to access data on host computers.
