I was just listening to the Antic Podcast interview with Bruce Carso (owner of B&C Computers) and he mentioned that he had a Mat Mania Challenge prototype along with some other prototype stuff in his warehouse. I know he's mentioned it before in the past, but was always too busy to look for it. Has anyone contacted Bruce about it? He mentioned a few other protos (Midi Maze, Commando, Xenophobe) but all of those have been released. Mat Mania is the only one that still remains unseen.
