Simon

Simon was a tabletop disc rather than a handheld, but no electronic toy of the era is better remembered. Ralph Baer and Howard Morrison designed it after seeing Atari's Touch Me arcade game, swapping its harsh beeps for four bugle-like notes tied to the four colored pads. Milton Bradley launched it in 1978 at Studio 54 in New York, and the game is simply repeat the sequence, one step longer each round, until your memory gives out.
