Indy 800 is an arcade racing video game released in 1975 by Atari Inc.[1] It was distributed in Japan by Nakamura Seisakusho (Namco).[2]
The game is housed in a large custom rectangular cabinet that takes up 16square feet. Each side of the cabinet has two steering wheels and four pedals. The 25-inch monitor is set in to the top face of the cabinet and looked down upon.[3] The game uses a full color RGB display and does not use color overlays.
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.
The cabinet also features overhead mirrors to allow spectators to watch the game while it's being played.
Gameplay is a simulation of an Indianapolis 500 style race, in which players compete by racing each other with simulated IndyCar race cars. The players race blocky cars around a simple track with a top-down overhead view. The player car colors are purple, peach, yellow, green, light blue, white, red and dark blue.
In March 1976, the first annual RePlay arcade chart listed Indy 800 as the fourth highest-earning arcade video game of the previous year in the United States, below Tank, Wheels and Gun Fight.[4] Later in October, RePlay listed Indy 800 again as the fourth highest-earning arcade video game of 1976 in the United States, below Sea Wolf, Gun Fight and Wheels.[5] In Japan, it was the tenth highest-grossing arcade video game of 1976.[6]
