Technology

The game is housed in a large custom rectangular cabinet that takes up 16 square feet (1.5 m²). Each side of the cabinet has two steering wheels and four pedals. The monitor is set in to the top face of the cabinet and looked down upon. The game uses a 25 inch full color RGB display and does not use color overlays, representing the first full color video game.

The processing electronics consist of a card cage that includes a "Backplane" or "Motherboard", eight identical car function boards, and three unique, common processing boards that the backplane board supports and interconnects. Each of the eleven boards has its own onboard fixed 5 volt regulator IC. All of the logic circuitry is TTL, and no microprocessors are used.

Each game was sold with two spare car boards and one each of the three processing boards, so that the game owner could repair it by simple circuit board substitution. Two "card extender" boards were furnished with each game sold that enabled technicians to probe individual components on suspect boards while they were still operating in the game. A complete set of circuit board logic diagrams was also furnished, as was a set of schematics for the modified GE color monitor.
