The playfield layout is the same as Bell Coin Matics' 1979 'White Shark'. This game is a conversion kit. The playfield and backglass pictured here were taken from a water-damaged Bally's 1977 'Evel Knievel' cabinet having the original Bally MPU with "EK" ROMs. The playfield layout generally resembles Bally's 1978 'Playboy'. The playfield artwork partially obscured by the lower pop bumper looks like the head of the robot on the backglass of Gottlieb's 1979 'Pinball Pool'. The backglass artwork first appeared on one of the advertising posters for the 1979 movie, Moonraker.
