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!

I'm looking to get my hands on a California
Computer Systems Model
2810 Z-80 CPU card. This is an S-100 bus card. Anybody out there
have one they want to sell?
I'm also looking for a readable schematic for this card.
I have one of these in my IMSAI system; I've had it for nearly 25
years. I used it daily back then. It's definitely not for sale. I
did see one go on eBay a few months ago for (I think) about $100.
I've put the documentation for this board (which includes a sorta-
readable-but-not-great schematic) up at:
