Its 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 Unix Version 6). 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 charsets (KOI-8 and U-code, used in DEMOS 1 and MNOS, respectively).

Later it was ported to Elektronika-1082, BESM, ES EVM, clones of VAX-11, and a number of other platforms, including PC/XT, Elektronika-85 (a clone of DEC Professional), and a number of Motorola 68020-based microcomputers.

The originally suggested name was УНАС (UNAS), which was a volapukish word play on Unix; "у них" ("u nih") in Russian means "at theirs" , "у нас" ("u nas") means "at ours", but a more serious management dismissed this idea in favor of a traditional "alphabet soup".
