SCP 1875 is a Victorian-era chess automaton consisting of a steel chessboard table, a complete set of 32 chess pieces, a stationary steam engine, and a suit of 18th-century Samurai armor. The SCP1875 table contains a sophisticated mechanical and biological system that controls a matrix of 64 electromagnets using an analytical engine composed of the combined brain tissue of the twin daughters of a Russian chess prodigy.
