Thanks for the pdf Dave. Unfortunately that's the same one I've found
floating around and the schematic is so badly pixelated that the
details can't be made out. I did hear from Herb Johnson at
retrotechnology and he has a copy for sale which includes a full size
foldout schematic. I think I'm going to bite the bullet and buy a
copy from him.
By the way, that PDP-11/70 looks awesome!
