Hi All,
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.
Thanks,
-Mardy

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:

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!

Sounds good. Would you be willing to scan it?

I have the manual and can try to scan the schematic page if you still
need it. I agree the one on the internet sites is very poor so let me
know. Herb's scans are good also.

A good copy has just turned up. Thanks anyway, though!
