M-20 [ru], M-220 [ru] and M222 were a range of general-purpose computers designed and manufactured in the USSR. These computers were developed by the Scientific Research Institute of Electronic Machines and built at Moscow Plant of Calculating and Analyzing Machines [ru] (SAM) and the Kazan Plant of Computing Machines (under the Ministry of Radio Industry of the USSR).

Operating systems
