Super hard-to-find Atari Jaguar Cat Box. Plugs in to the expansion port on the back of the Jaguar to give S-video out and networking functions. I plugged it in and the eyes light up like they're supposed to but I did not have an S-video cable to test it with. I have no reason to believe there is anything wrong with it but it is being sold as-is.

This Cat Box comes complete with the network cable needed to connect two Cat Boxes and Jaguars for network play. I don't believe this cable has ever been out of the package.

I currently have a second Cat Box on eBay without the networking cables. If you want to play some networked Doom, grab them both!
