Electronika 60
The Electronika 60 is a Soviet minicomputer released in 1978 and meant to clone the DEC LSI-11, a variant of the PDP-11. Like the LSI-11, the Electronika 60 is rack-mounted and doesn't have any built-in IO or storage.
Although little more than a clone, the Electronika 60 is notable because it is the computer on which Alexey Pajitnov developed Tetris.
