SM-1420

The SM-1420 (CM-1420) is a 16 bit DEC PDP-11/45 minicomputer clone, and the successor to SM-4 in Soviet Bloc countries.[1] Under the direction of Minpribor it was produced in the Soviet Union and Bulgaria from 1983 onwards,[1][2] and is more than twice as fast as its predecessor.[3] Its closest western counterpart is the DEC PDP-11/45, which means that the Soviet technology trailed 11 years behind compared to the Digital Equipment Corporation equivalent machine.[4]

The standard package includes 256 KiB MOS memory, two RK-06 disks, two TU-10 decks, CM-6315 barrel or DZM-180 dot-matrix printer from Mera Blonie (Poland), VT52 compatible or VTA-2000-15 (BTA 2000-15) VT100 compatible terminals from Mera Elzab.
