Atari 2700

While It is unclear how many of these systems exist, former Atari employee Dan Kramer has stated that at least 12 consoles were made (one is owned by The National Videogame Museum), plus extra controllers.

The casing featured a hinge-topped storage bay for the wireless controllers and a built-in belly groove for winding excess cable to connect to a TV.

Although they were the primary innovation of the 2700, it was the wireless controllers that actually caused the console to be cancelled prior to release.

Although abandoned, the 2700 case design became the model for a number of later Atari game systems, notably the very similar looking Atari 2800[3] for Japan and the similar Atari-made Sears-branded Video Arcade II, both of which featured (wired) controllers which combined the functions of joystick and paddle.

The 2012-released Atari Flashback 4 also features wireless controllers based on infrared technology.
