You would have to suggest hand wiring :-). The proto capes I've seen don't look big enough for the dip buffer chips and connectors, but I'll look at that option a little bit more. I guess I could use generic perf board material while I'm at it. I wonder if I have enough wire-wrap sockets and wire to go really retro?
