Released November 1982 The Atari 5200 is a video game console introduced in 1982 by Atari. It was created to compete with the Mattel Intellivision, but it also competed with the Colecovision shortly after the 5200's release. In some ways, it was both technologically superior and more cost efficient than any console available at that time.
The Atari 5200 was in essence an Atari 400 computer without a keyboard. This made for a powerful, proven design which Atari could quickly bring to market. The system featured many innovations like the first automatic TV switch box, allowing it to automatically switch from regular TV viewing to the game system signal when the system was activated.
The initial release of the system featured four controller ports, where all other systems of the day had only two ports. The system also featured a revolutionary new controller with an analog joystick, numeric keypad, two fire buttons on both sides of the controller and game function keys for Start, Pause, and Reset.
