"The Synthcart is a unique Atari 2600 cartridge that turns your 2600 into a pop music sensation, letting you play music using a pair of Atari's keyboard controllers and can also be controlled with an optional 2600 MIDI kit.

AtariAge sponsored a Synthcart Beat Programming Contest in early 2002 to allow people to create and contribute beats to be included with the Synthcart.
