Spectra IV, produced by The Valley Company, a subsidiary of Walter Kidde & Co., Inc., in 1978, is a solid-state, cocktail-style pinball machine notable for its rotating playfield. This unique design allows up to four players to participate without changing positions, as the playfield manually rotates beneath a stationary glass top. The game features two flippers, three pop bumpers, a rollunder spinner, a captive ball, kick-out holes, and a left kickback lane
