OK, I was mistaken. Yes, it is a IIcx adapter. I have that adapter and it worked when I plugged it into the '030 SE/30 socket.

The main problem is that routing the connection would be very difficult. I am willing to help out on figuring out the connections. If we come up with a schematic, I am sure the collective minds here could come up with a nice solution.

If only we could replicate the '030 PowerCache board.
