I was going to post about my PDP-8/A repairs at the recent workshop; the 
linked WEb page has details. When I read Evan's post about his LEGO Logo 
Robo go-go work, I added some photos and links about that, to my Web page.

I looked with effort on the Web for "da schematic" for the motor 
controller, the thing that was "jumpered" in posted discussion. I was 
surprised to NOT find it. There's info on the Apple II interface card 
already, as discussed. Odd someone with skills, hasn't drawn this 
already. There's the usual reasons, mostly like these things are already 
available for tens of dollars used.

Ah - this Web page is informative:
