(D-SUBminiature connectors) A family of plugs and sockets widely used in communications and on earlier PCs. For example, the analog VGA monitor interface uses a D-sub 15-pin plug and socket.

Anyone ever had to repair a D-sub 15 pin VGA cable? We've got a 35 foot cable in our conference room that is damaged right near the connector. I've been tasked with repairing it if possible.

Sun, SGI, NeXT… a few companies used DB13W3. Of course Sun uses composite sync, SGI uses sync-on-green… so plug a Sun GDM5410 monitor into a SGI Indy and it’ll just sit there and look stupid.
