Popular games for collection Gran Trak 10

Gran Trak 10 was a single-player racing arcade game released by Atari in 1974. 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.

Gran Trak 20 is the follow-up to Gran Trak 10. Unlike the original game it allows two people to race each other, a significant innovation since neither game features computer-controlled cars.
