An Atari Jaguar and CD combined into one base unit. Atari hyped the Jaguar CD for like a year, and then finally debuted it with three games. To my knowledge no new ones were ever made as by that time the Jaguar was pretty much dead as a doornail. Makes you wonder how much money they could have saved/made if they just would have gone CD with the base unit in the first place (a lesson Nintendo would learn with he N64 a year later.) Should play all Jaguar cart/CD games, and there's at least a couple of hundred floating around (former test units) as well as probably a warehouse of mint boxed units sadly awaiting a release date that will never come somewhere.
