Instrumentalnaya mobile operating system, ИНМОС, or Instrumental Mobile Operating System, INMOS is an operating system developed in 1983-1985 in the USSR. This system is an adaptation of the UNIX operating system for Soviet computers - initially for the SM family of computers and then (in 1987) for the Iskra-1030 personal computer.

Attempts were made to adopt INMOS as a standard, but due to general changes in the country and the presence of "competing" Unix implementations (DEMOS), they were not successful.
