Ok, so this suggests a possible solution/idea. We use simm sockets. You can
get them fairly cheaply, there is a wirewrap version, and the PC houses all
have a standard template for the bottom of the board. I suppose one could
even make a Q-bus that small (its 72 pins as well IIRC).

Unlike Tim I think TO-3's would be way to much of a pain, but TO-92s are fine.
