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. :)

    I HAVE BEEN DIAGNOSED!

    I have ADHD, primarily inattentive (obviously some hyperactive traits but not enough). I am on the Autism spectrum with “level one support needs.” I feel bad for saying this, but I am in the 98th percentile in regard to the “intelligence quotient” (imperfect working memory). Anxiety and depression were not bad enough at the time of the test to qualify as a disorder.

    I should be trying some “legal speed” at some point.

    No new knowledge but it’s nice to have someone with a fancy label agree with me and prevent imposter syndrome.

      lets-fucking-go Very exciting! Hope you can get meds soon and they help. I've heard a lot of good things about meds from people with adhd.

        Thank you! I’m doing fine not functioning most of the time and excelling the rest of it, but ADHD meds are literally the most effective medicine and I’m optimistic. How much more random research can I do when I’m not attached to my phone?

        You haven’t done a massive amount of research and speculation already? (Tbf I only did so in the last five months)
