This wasn't known of until recently. Seems like SOJ sent these guys a lot of stuff for their upcoming book on the history of the Dreamcast. I think they sent them the actual prototype unit! I don't know if it is for them to keep but I REALLY would love to see more about it, and if they could take some 3d scans of it so people could 3D print a replica case to put their systems inside.
