The MS4100 Series, marketed in June 1986, adopted a multiprocessor system based on 32-bit VLSI with 50,000 gates fabricated using CMOS technology. By using a dedicated UNIX processor, it enabled simultaneous execution of the NCOS1/AF operating system for real-time processing, and the "MX-UX/V" operating system which conformed to UNIX System V. Due to its use of multiprocessors, pipeline control and memory interleave speedup technology, the MS4100 Series was the fastest in this area.
