SM-1420

The SM-1420 (CM-1420) was a 16 bit DEC PDP-11/45 minicomputer clone, and the successor to SM-4 in Soviet Bloc countries. Under the direction of Minpribor it was produced in the Soviet Union and Bulgaria from 1983 onwards, and was more than twice as fast as its predecessor. Its closest western counterpart was the DEC PDP-11/45, which meant the Soviet technology lagged 11 years behind compared to the Digital Equipment Corporation equivalent machine.
The standard package included 256KB 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.
