DEMOS (Dialogovaya Edinaya Mobilnaya Operatsionnaya Sistema: Russian: Диалоговая Единая Мобильная Операционная Система, ДЕМОС, lit. ‘Interactive Unified Portable Operating System’) is a Unix-like operating system developed in the Soviet Union. It is derived from Berkeley Software Distribution (BSD) Unix.
It’s development was initiated in the Kurchatov Institute of Atomic Energy in Moscow in 1982, and development continued in cooperation from other institutes, and commercialized by DEMOS Co-operative which employed most key contributors to DEMOS and to its earlier alternative, MNOS (a clone of Version 6 Unix). MNOS and DEMOS version 1.x were gradually merged from 1986 until 1990, leaving the joint OS, DEMOS version 2.x, with support for different Cyrillic script character encoding (charsets) (KOI-8 and U-code, used in DEMOS 1 and MNOS, respectively).
Initially it was developed for SM-4 (a PDP-11/40 clone) and SM-1600. Later it was ported to Elektronika-1082, BESM, ES EVM, clones of VAX-11 (SM-1700), and several other platforms, including PC/XT, Elektronika-85 (a clone of DEC Professional), and several Motorola 68020-based microcomputers.
The development of DEMOS effectively ceased in 1991, when the second project of the DEMOS team, RELCOM, took priority.
An archive of the DEMOS source code can found here: https://github.com/bpr97050/DEMOS There’s some interesting comments and mailing list archives in that repository as well. :)

Finally found the time to do some of the thrifting I wanted to do. I got some women’s jeans to try on (hopefully they fit. If not, I’ll at least know how to size up/down) as well as some jewelry.
In an not particularly gender related note, also picked up a print copy of the Borealis Connection campaign for The Fall of Delta Green trpg. Not sure if I would want to run it with the FoDG Gumshoe system (which is fiddly but neat) or with the regular d100 Delta Green system, but this sort of late 60s conspiracy thriller is something that I’ve wanted to run for a while.
