EWS-UX is a Unix operating system used by NEC Corporation for its {{ill|EWS4800|jp|EWS4800}} line of engineering workstations.{{Cite web |title=EWS4800/220, EWS4800/260 |url=https://museum.ipsj.or.jp/en/computer/work/0011.html |access-date=23 October 2024 |website=IPSJ Computer Museum}}{{Cite newsletter |date=September 1998 |title=Implementation Status of Electronic Library Service |url=https://www.nii.ac.jp/ENEWS/NL18/1816.html |access-date=23 October 2024 |magazine=NACSIS Newsletter |issue=18 |issn=0915-7018}}{{Cite web |date=January 1994 |editor-last=Kailey |editor-first=Judy B. |editor2-last=Himes |editor2-first=Peggy N. |title=VALIDATED PRODUCTS LIST 1994 No. 1 |url=https://nvlpubs.nist.gov/nistpubs/Legacy/IR/nistir5354.pdf |access-date=23 October 2024 |website=NIST |page=35}} EWS-UX is based largely on versions of Unix System V supplemented with BSD software.{{Cite report |url=https://library.eecs.utk.edu/files/ut-cs-96-325.pdf |title=Overview of Recent Supercomputers |last=van der Steen |first=Aad J |last2=Dongarra |first2=Jack J |date=May 1996 |publisher=University of Tennessee Knoxville |edition=6th |pages=35, 67}} 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.{{Cite web |date=2 March 1998 |title=Mechanical CAD/CAM/CAE worldwide, 1998-1999 |url=https://archive.computerhistory.org/resources/access/text/2013/04/102723362-05-01-acc.pdf |access-date=23 October 2024 |website=archive.computerhistory.org |publisher=DataQuest |page=27}}
Early versions of EWS-UX run on Motorola 68000 series CISC processors,{{Citation needed|date=October 2024}} while later versions run on MIPS RISC processors.{{Cite news |date=14 May 1992 |title=SEEKING STRENGTH IN NUMBERS AGAINST US ONSLAUGHT, NEC, SONY MAKE MIPS BOXES COMPATIBLE |url=https://www.techmonitor.ai/technology/seeking_strength_in_numbers_against_us_onslaught_nec_sony_make_mips_boxes_compatible/ |access-date=23 October 2024 |work=Tech Monitor}}
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|date=October 2024}}
EWS-UX and {{ill|UP-UX|jp|UP-UX}} (NEC's Unix server OS) became integrated and merged into {{ill|UX/4800|jp|UX/4800}}.{{Citation needed|date=October 2024}}
Versions
- EWS-UX / V: Based on Unix SVR2. It runs on the EWS4800 series equipped with the MC68020, MC68030, and MC68040 processors.
- EWS-UX / V (Rel4.0): Based on Unix SVR4. It runs on the EWS4800 series equipped with R3000 ({{ill|VR3600|jp|R3000#派生品}}) and R4000 processors.
- EWS-UX / V (Rel4.2): Based on Unix SVR4.2. It supports processors such as the R4400, {{ill|VR4200|jp|VR4200}}, and R4600.
- 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.
