I whipped this up tonight. Cost around $5 in parts and 15 minutes with a Dremel to shape the connector. Fits the expansion port like a glove, all pins have good connections. Working on rewiring the USB keyboard adapter to run through this.
It's an old 16-bit ISA connector. You can either sacrifice an old motherboard or order one from one of the shops like Digikey. Here's how I did it...
1. Using a cutoff wheel, remove the ends so that the length matches the port.
2. Very carefully cut it in half longways from the bottom.
3. Use a sanding wheel to reduce the thickness of the outer plastic as well as the inner plastic below the contacts.
4. Looking at the top of the connector, bevel the outer edges. This way it will be easier to slide into the expansion port.
