EWS-UX

EWS-UX is a Unix operating system used by NEC Corporation for its EWS4800 [jp] line of engineering workstations.^[1][2][3] EWS-UX is based largely on versions of Unix System V supplemented with BSD software.^[1][4][2] It was widely used from the late 1980s to around 2000.

Overview

EWS-UX and the EWS-4800 line of workstations were widely used for CAD / CAM work.^[5]

Early versions of EWS-UX run on Motorola 68000 series CISC processors,^{[citation needed]} while later versions run on MIPS RISC processors.^[6]

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.^{[citation needed]}

EWS-UX and UP-UX [jp] (NEC's Unix server OS) became integrated and merged into UX/4800 [jp].^{[citation needed]}

Versions

1. EWS-UX / V: Based on Unix SVR2. It runs on the EWS4800 series equipped with the MC68020, MC68030, and MC68040 processors.
2. EWS-UX / V (Rel4.0): Based on Unix SVR4. It runs on the EWS4800 series equipped with R3000 (VR3600 [jp]) and R4000 processors.
3. EWS-UX / V (Rel4.2): Based on Unix SVR4.2. It supports processors such as the R4400, VR4200 [jp], and R4600.
4. EWS-UX / V (Rel4.2MP): Based on Unix SVR4.2MP. It supports multi-processor systems using the R4400MC. It is mostly similar to UP-UX, NEC's Unix operating system for servers.
