Say hello to the Nintendo PlayStation. Sam Machkovech SEATTLE—Terry and Dan Diebold's rise to nerd fame hinges on a single piece of hardware, but when the kit is this good, that's all you need. The father and son are proud owners of the only known Nintendo PlayStation console, a hybrid Super Famicom and disc-drive system that was co-developed by Nintendo and Sony in 1991. Thanks to Internet posts, we've seen the system's original, warehouse-related discovery, and we've seen a mighty impressive teardown thanks to hacker extraordinaire Ben Heck.
