Classic Game Room reviews the ATARI 5200 TRAK-BALL controller for Atari 5200 which works with games like Centipede and Missile Command (also Defender, Space Invaders and a few others). This old school piece of videogame hardware is a tank with a track ball in the center and buttons on the side. Plugs into Atari 5200 video game controller ports and works well with Centipede and Missile Command.
