Coleco Gemini
The Coleco Gemini is an Atari 2600 clone manufactured by Coleco Industries, Inc. in 1983. History. In 1982, Coleco released Expansion Module #1 for its ColecoVision video game system. Using off-the-shelf components, the module enabled the ColecoVision to be compatible with Atari 2600 software. Later that year, Atari, Inc. sued Coleco for patent infringement, and the companies wound up settling out of court, with Coleco becoming a licensee of Atari's patents. Gemini vs. 2600. The main difference between the Coleco Gemini and the Atari 2600 is the controller design. The Coleco Gemini controllers (dubbed the  'Dual Command') featured an 8-way joystick and a 270-degree paddle on the same controller (the joystick was at the top of the controller, and the paddle was at the bottom of the controller). To play paddle games on the 2600, a Y-connector could be used to connect a joystick and paddles to the controller jack at the same time, rather than physically swapping controllers. The Gemini was more compact than the large faux-woodgrain or gloss black-trimmed consoles sold by Atari at the time. The Gemini also had a different game included with the system. Atari  was including its 1982 version of "Pac-Man" along with "Combat" (1977). The Gemini initially came bundled with Coleco's 1982 port of "Donkey Kong", but at some point also included "Carnival", "Mouse Trap" and "Front Line". Sears also offered a version of the Gemini with both "Donkey Kong" and "Mouse Trap" included as separate cartridges.
