Minivac 601 Digital Computer Kit was an electromechanical digital computer product created by Claude Shannon and sold by Scientific Development Corporation as early as 1961 as an educational kit for digital circuits. It used electrical relays as logic switches and for storage. It had a six-bit binary input/output array, consisting of simple switches and indicator lights and a motorized dial to input decimal numbers or act as a clock signal. Its design just barely allowed it to play winning Tic-Tac-Toe.
