NEC ACOS-2/MP

ACOS-2/MP (which stood for “millennium processor”) was an operating system designed for NEC’s small mainframes. NEC announced the operating system in May 2000 and started shipments in July. The operating system ran on the Parallel ACOS i-PX7300 series, which used Intel processors as their CPUs. NEC also provided the ACOS-2/iPackage product suite to bring core systems up to speed with the Internet age. The iPackage gave entire systems seamless connectivity with open systems, Internet support, and enhanced infrastructure functionality.
