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. :)

    Thinking about the systemic rot of how this kind of shit probably happens to millions of people of my (our?) generation(s) as a symptom of austerity and atomization and alienation makes me so fucking livid and heartbroken for humanity

    This wouldn't happen to people in a sound society with an economic order that actually cares about people's wellbeing

    All of this is a consequence of the 2008 housing bubble collapse and great recession, and I want to redacted-1redacted-2 all the people responsible for it that are still out there and suffered no real consequences for ruining millions of people's livelihoods and sending them down a path of poverty and substance abuse

    I feel like spite is all that keeps me going sometimes out of the hope that I can live to see the no-excuses made terror come someday
