Atari Jaguar owners wishing to increase their system's output and communications capabilities will want to snatch up ICD's CatBox expansion peripheral. The CatBox plugs directly into the back of the Jag. redistributing outgoing signals into six output formats — three for audio (line-level stereo. RGB monitor, head-phone jack with volume control) and three for video (composite. S-video and analog RGB.) These connections make the Jaguar compatible with any number of high-quality monitor systems, and with multiple monitors at the same time. The CatBox also features three kinds of communications ports which allow two or more Jags to be connected for simultaneous multiple-player action on games like Doom.
