You can pick up a db15 connector at radio shack, but I warn you it may not be as noise free as your old one, and the wires *may* not be labled so figure out the pin patterns by removing the sheath ...

Also called "DB connectors" and "D-subs," they come in 9, 15, 25, 37 and 50 pin varieties. The D-sub designation defines the physical structure of the connector, not the purpose of each line.
