The device consists of a long cartridge with a handle on the end, and an audio cassette cable. It adds 6 KB to the Atari 2600's 128 bytes of RAM (increasing it 49-fold to 6,272 bytes of RAM), allowing for the creation of specially compatible games which are larger and have higher resolution graphics than normal cartridges. A cable coming out of the side of the cartridge plugs into the earphone jack of any standard cassette player, for loading all Supercharger games from standard audio cassettes.
