Atari 5200 4-port Switchbox Official and Original Atari 5200 4-Port Switchbox! Not For use on an Atari 5200 2-Port System! Extremely Rare and Difficult to find! On an Atari 5200 4-Port System, the power supply actually plugs into the switchbox, not the console, so you must have this device! You CANNOT buy a generic version of this at your local electronics store!
