Starpath Supercharger

The Starpath Supercharger was an add-on module created by Starpath to expand the game capabilities of the Atari 2600 video game console. The device resembled a long game cartridge with a handle on one end. The Supercharger interface added an extra 6 KB to the Atari 2600's 128 bytes of RAM (increasing its RAM 49-fold), allowing for larger games with higher resolution graphics. A cord coming out of the side of the cartridge plugged into the earphone jack of any standard cassette player. Games for the Supercharger were stored on normal audio cassettes.

By providing these capabilities, the Supercharger made the Atari 2600 much more like the low end home computers of the era, aside from the alphanumeric keyboard the console lacked (simple numeric keypads were available from Atari as add-ons, however).
