In May 1990, NEC announced NEC Superstation EWS4800/220 (desktop type) and NEC Superstation EWS4800/260 (floor type), equipped the R3000 RISC microprocessor from MIPS Computer Systems (USA). The world's highest integer operation speed for a desk-top was achieved by equipping the EWS4800/220 with the R3000 (which had a clock frequency of 30megahertz). These machines also had a high-speed drawing mechanism as standard equipment, and a drawing capability of 400,000 short vectors per second, and they were marketed as workstations suitable for use in a wide-range of fields requiring high-speed processing, such as computer-aided engineering, artificial intelligence image processing and dealing.
The EWS4800/220 and 260 were the first machines in Japan to be equipped with an OS conforming to UNIX System V Release 4.0.
