EWS-UX is a Unix operating system used by NEC Corporation for its EWS-4800 line of engineering workstations. EWS-UX is based largely on versions of Unix System V supplemented with BSD software. It was widely used from the late 1980s to around 2000.
EWS-UX and the EWS-4800 line of workstations were widely used for CAD / CAM work.
Early versions of EWS-UX run on Motorola 68000 series CISC processors, while later versions run on MIPS RISC processors.
NEC attempted to introduce binary compatibility between Unix versions used by DEC, Sony (NEWS-OS), and Sumitomo's Unix (SEIUX). However, DEC dropped out of the agreement to pursue the DEC Alpha architecture.
EWS-UX and UP-UX (NEC's Unix server OS) became integrated and merged into UX/4800.
