The plug to fit the A/V port of the Sega Saturn. It is a standard part of the mini-DIN series after all. Here's a picture of one I received as a commercial sample.
Very Cool Tim. Where did you end up locating it? I would like getting my hands on a few. Great find man!
It came form a taiwanese company called 4UCON Technology. It's listed with a MOQ of 5000 pieces. :/
Hell. I don't think there are that many Saturns in operation right now, and I'm a guy with three plugged into his TV. :) Maybe Radio Shack will end up using male/female pairs for their next game controller extension cable... except that all current game systems have wireless pads. Damn you, progress!
