Gran Trak 20

Gran Trak 20 is a racing game by Atari. It is a two-player variant of Gran Trak 10. Two players race against each other and the clock in an attempt to complete as many laps as possible. There are also oil slicks on certain parts of the track that will prevent the car from steering. While mostly analog with discrete circuitry, diode-based ROMs are used to store graphics.
