ES EVM

ES EVM (ЕС ЭВМ, Единая система электронных вычислительных машин, meaning "Unified System of Electronic Computers") was a series of clones of IBM's System/360 and System/370 mainframes, released in the Comecon countries under the initiative of the Soviet Union since the 1960s. Production continued until 1998. The total number of ES EVM mainframes produced was more than 15,000.

In the period from 1986 to 1997, there were also produced a series of PC-compatible desktop computers, called ПЭВМ ЕС ЭВМ (Personal Computers of ES EVM series); the newer versions of these computers are still produced under a different name on a very limited scale in Minsk.
