Yes, I realised after sending the email that I
would really need the
PCB side of things. I think there are kits for making one-off PCBs, so
I could
Yes, there are home etching kits, but making edge conenctor patters is not
trivial. Layign them out and etchign them is, but if you leave them as bae
copper they will oxidise fast and you'll get poor connections.
Tinnign them helps, but the best thign to do is gold-plate them and that's
not somethign you can sensibly do at home (the chemicals involved are very
toxic -- cyanides, for example). Not all PCB manufacturers can do gold
plating either.
Of your experiments, I think I'd use a couple of ribbon cabels ending i row header sockets (easy to get too). Those will plug
onto most controller
boards in place of the cabels ending in edge connectors that went to the
drive. Then you wouldn't need a special PCB at all.

What I think you are suggesting is to make up a replacement ribbon cable
with the more usual edge connectors. That is a great idea, but if I am not
mistaken, tooling up to create your own custom ribbon cables can be
expensive, or it might have been that you couldn't easily buy smallish
quantities of ribbon cable. I can't remember for sure now. Still, it
definitely a much better idea than my original one!
