Released November 1982 In 1982, Coleco released Expansion Module #1 for its Colecovision video game system using off-the-shelf components. Atari sued Coleco for patent infringement, however a court ruled that since Coleco used off-the-shelf components and not the same components found inside an Atari 2600, the Expansion Module #1 did not infringe on Atari's patents for the 2600. With this ruling, Coleco decided to make a stand-alone Atari 2600 clone and named it the Gemini.
The main difference between the Coleco Gemini and the Atari 2600 is the controller design. The Coleco Gemini controllers 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). Unfortunately, if one wanted to play the Atari 2600 game Warlords in 4 player mode, 2 sets of Atari-made paddles were required, and one set of Atari-made paddles was required for 2 player paddle games.
