I'm searching for info on a California Computer Systems S100 board:

Model 2805
Terminator/Wallclock
Assy No. 02805-00001
REV A

I've found a few people with pictures, and one of the other CCS manuals mentions it in describing interrupt chain layout. In particular, I'm trying to get the part numbers for the resistor packs that make up the terminator -- someone kindly diked them off of my board. I'm pretty sure I have a part number for the 330R/390R packs, but I can't find one for the 1K packs, and I'm wondering if they're actually just pull-up packs instead of dual terminators. Any help is appreciated!
 
Did you ever find documentation for the CCS 2805 terminator/wallclock?
I just found two… but no documentation… :(
 
I found the CCS 2805 TERMINATOR/WALLCLOCK (REV B) Manual…
I scanned the terminator schematic page but I cannot upload it (256k limit).
If you still want it you may email me at: <g e o w a r 1 @ m a c . c o m> (without spaces).

From the parts page the Z4 & Z5 parts are Network, SIP, 1K x 16, CCS part # 47400008.

On both parts pin 8 is ground and pin 16 is +5V.
All other pins are 1K to the +5V pin.
