Gran Trak 10

In Gran Trak 10 the player raced against the clock, accumulating as many points as possible. Primitive diode-based ROM was used to store the sprites for the car, score and game timer, and the race track. The game's controls — steering wheel, four-position gear shifter, and accelerator and brake foot pedals — were also all firsts for arcade games. Steve Wozniak famously played Gran Trak 10 during the four-day development of a prototype for another Atari game, Breakout. Source: Wikipedia, "Gran Trak 10", available under the CC-BY-SA License.
