Minivac 601 Digital Computer Kit was an electromechanical digital computer system created by information theory pioneer Claude Shannon and sold by Scientific Development Corporation as an educational toy using digital circuits.[2]

Description

In 1961, the system was sold by Scientific Development Corporation's "Consumer Products Division",

SPDT pushbutton switches, and indicator lights. A 16-position motorized dial rotary switch could be used to input decimal or hexadecimal numbers, to output numbers, or to act as a clock signal
generator.

The components could be interconnected by manually inserting

Tic-Tac-Toe, or to simulate a simple elevator
control system.

An "advanced and improved" version called the Minivac 6010 was released in early 1962, housed in a gray metal case and featuring higher-quality components.
