The Atari CoJag is an arcade board released in 1995 by Atari Games (a then-subsidiary of Time Warner Interactive that licensed the console hardware) before Atari Corporation's reverse merger with JT Storage. It was based on the Atari Jaguar chipset. It features nearly identical hardware that doesn't differ from that of the console except for its system processor. The standard 13.825 MHz Motorola 68000 was replaced by either the 25 MHz Motorola 68020 or the 33 MHz MIPS R3000.The RAM for games (the Atari Jaguar features 2 megabytes of RAM whereas the Atari CoJag uses 4 megabytes for Area 51 and 6 megabytes for Maximum Force) and the 64-bit ROM bus (the Jaguar features the 32-bit one). The arcade board is composed from the chipset and hard drive with an HDD (1 gigabyte for Area 51 and 2 gigabytes for Maximum Force) that features a game (except in case of the leaked prototype games which only exist with ROMs), and a JAMMA wiring harness. Compact Flash-To-IDE boards could be used by modders instead of HDDs. Interestingly, unmodified boards also used as the main controller for kiddie rides by Carousel International, which are no longer manufactured: Speedster II, Skycopter II, and SpaceGuy (never released), but could have been previously spotted in Chuck E. Cheese pizza parlors (founded by Atari's co-founder Nolan Bushnell). All the rides were programmed by Mario Perdue, who wrote Breakout 2000.^[1] Also, the CoJag supports 2 light guns instead of 1 supported by the Jaguar.

Only 2 games (and their combo) were officially released:

• Area 51
• Maximum Force
• Area 51/Maximum Force Duo (combines both games in a single cabinet)

4 unreleased prototypes exist:

• Fishin' Frenzy
• Freeze
• Vicious Circle
• 3 on 3 Basketball
