I haven't read the thread as I need my sleep but I was posting about my mouse and saw your bridgeboard reference in the thread title and was reflecting on the fact that I uncovered an AT Emulator Sandwich Board or BD made in West Germany in 1988 today. I do have the board it slots into so they can be reunited. This board has had so much work done to it. Tiny wires all over the place. Folk that struggled to get the boards working were very dedicated. How you work out what wire does what I wouldn't have a clue. It's a nice have I guess and good to hold in the hand. Don't think it'll ever find its way inside any of my 2000s. I never saw the point of the emulator to be honest. I have a 1060 on a 1000 which works but its dull as soup.
I'll catch up with your thread sometime when I get a spare week. Looks very popular. Keep it up.
