SM EVM
SM EVM are several types of Soviet and Comecon minicomputers produced from 1975 through the 1980s.
Most types of SM EVM are clones of DEC PDP-11 and VAX. SM-1 and SM-2 are clones of Hewlett-Packard minicomputers.
The common operating systems for the PDP-11 clones are translated versions of RSX-11 for the higher spec models and RT-11 for lower spec models. Also available for the high-end PDP-11 clones is MOS, a clone of UNIX.
