But as you don't mention a second card, I'm going to assume you haven't
noticed the jumper card hidden inside the punch.
Hmm, I was too lazy to take the base plate off (the punches already have a
ton of stuff piled on top), but I was able to see the small cards with a
flashlight. The one in the Facit looks like it has three socketed chips
in it with several kludge wires. The one in the HP looks like it has a
bunch of transistors on it, but no IC's.
When I'm ready to test these pups out, I'll take a closer look at the
boards.
OK, here's the pinout
Thanks! Another pearl for future researchers to find in the archive.
