Ideally one would make a universal card - like the VERO boards but with the 0.1" (?) 100 pin connector and the rest of the board full of plated through holes...

Then if folks scan their cards on both sides (or photo) someone can draw up the wiring.
As I seem to have the largest single collection I'll be scanning/photographing them this spring with my work experience students. I'll leave it to someone else to do the wiring though, I have way too many projects to finish that are needed to pay bills. I will post the pictures on flippers though as they are done.
I have replacement 100 pin wire wrap sockets for the test fixture for sale if anyone needs one.
I also recommend that you fuse the transformer secondaries to avoid burning cards or edge connectors if a problem occurs (don't ask).

Oh, and considering that the last six pins on the two Program connectors (A & B) aren't used I've hooked four of them (49a(top) & 49a(bottom), 50a(top) & 50a(bottom)) up to two added internal speakers (old PC tiny ones) to simplify testing. As for prototype cards, I'd take a bunch (10 to 20) for making up missing cards...
