rfm video amp project

[pinball god]

For my video amplifier project on a rfm pinball. I thought I had saved a couple of these cables but cannot find anywhere. They are the red/yellow/black adapters that you use to plug into a spare plug from the pc case power supply and it would be an adapter to plug into a 3.5inch floppy drive. So it had a larger end to plug into the power supply and a smaller plug the other end for the floppy drive.

 Would anyone have one or two lying around they don't want? Much appreciated if you do. This will quickly enable me to tap into a 5v source for the video amp. Thanks

Thanks mate. Btw is there any particular size of wire required for video interface? I need to buy some for the interface cable.
