One idea is if there are any computer salvage places around, try there. There is a place downtown here, an electronics surplus store, and they have TONS of stuff. Sound cards, video cards, some of which do not work - however, the attachments are still in good shape. The cards themselves do not work, but the hardware is in great shape... so they are very cheap and you can get the pieces you need off of them. I am not sure, but I will try to find out if they have a website you can order from.
It's great, you can pick up a 486DX 33 or 66MHz for $25, monitor and everything. Older Sierra games work great on older PCs.... and for $25, if you have the room, why not?
