I still have the proprietary cable that lets you hook up a 1992-ish Sony Handycam to a TV with RCA inputs.
I know exactly where it is in my attic: Under the S video cables, an original FireWire cable, and the cable that lets you hook up two Atari Lynx portable consoles together in order to play Warbirds against each other in real time.
I think you're suffering from the same vice as little Miss Spelings.
A vice grip would truly be an immoral tool.
