'''Mobile Operating System''' ('''MOS'''; {{Langx|ru|'''Моби́льная Операцио́нная Систе́ма''' ('''МОС''')}}) is an [[operating system]], a [[Soviet Union|Soviet]] [[Clone (computing)|clone]] of [[Unix]] from the 1980s.<ref>Balodis, Rihards; et al. [https://doi.org/10.1007%2F978-3-642-23315-9_51 "History of Nordic Computing 3"] IFIP Advances in Information and Communication Technology, 2011, Volume 350/2011, 453-461; "The common operating system was MOS, a clone of UNIX."</ref>

==Overview==
This operating system is commonly found on [[SM EVM]] [[minicomputer]]s; it was also ported to [[ES EVM]] and [[Elbrus (computer)|Elbrus]]. MOS is also used by high-end PDP-11 clones.

Modifications of MOS include [[MNOS (operating system)|MNOS]], [[DEMOS]], {{Interlanguage link|INMOS (operating system)|lt=INMOS|ru|ИНМОС}}, etc.
