I imagine a dystopian future where the government controls the supply of computer cables, forcing a select few dealers to hock their wares in dark alleyways. You're not going to like their prices, but sometimes you just gotta upgrade to DVI.
From submitter azgli: The speaker system at a friend's party was missing a proprietary 13-wire cable between the main unit and the speaker controller. This was my solution to the problem - 13 individual wires insulated with Scotch tape! More Scotch tape kept them from shorting when the sub started rattling things around.
