PDP-11 is a series of 16-bit and 22-bit computers by Digital Equipment Corporation, which began production in 1970.

In 1994, DEC sold the software rights to the PDP-11 to Mentec. DEC ceased the production of PDP-11 computers in 1997.

Unlicensed clones

The Union of Soviet Socialist Republics, and after the Soviet Union collapsed, countries in the Eastern Bloc, created several PDP-11 compatible machines. The Soviet Union manufactured several PDP-11 compatible computers in their factories, including the Elektronika BK home computer line.
