The Electronika 60 (Russian: Электроника 60) is a computer made in the Soviet Union by Elektronika in Voronezh from 1978 until 1991. It is a rack-mounted system with no built-in display or storage devices. It was usually paired with a 15IE-00-013 terminal and I/O devices. The main logic unit is located on the M2 CPU board.

The original implementation of Tetris was written for the Electronika 60 by Alexey Pajitnov in 1985.[1] As the Electronika 60 does not have raster graphics, text characters were used to form the blocks.[2]
