Hi
I'll start a new topic here regarding getting the CCS system running.
Old discussion is here
Long story short, I got a CCS S-100 system for free a while ago, which I cannot get to work properly.
It has those cards inside, all CCS:
- CCS 2065 64K RAM
- CCS 2422 FDC
- CCS 2810 CPU
- CCS Paralell/Serial card
Manuals are here
In addition I have those two cards (Not inside the system)
- Cromemco DPU
- Cromemco STDC
The system does not work, and below is the last results from my tests:
I measured the voltages and they seem OK.
I cleaned the CCS CPU Card and replaced all the corroded jumpers. I reseated _every_ chip on the card and followed the manual in how to enable the built-in monitor.
No response over serial whatsoever. No garbage, no nothing. The LED's on the card does not light up, and if I put in the memory card, the LED on the memory card does not light up either..
If I put in the Cromemco DPU card things start to act a little different. The Memory card lights up, the floppy controller flashes it's "sel" LED and the two others are on solid. On the DPU card the "Z80" LED lights up.
Nothing on the serial port.
Based on the above, I am almost certain that the CCS CPU card is wasted one way or another. The only thing that gets hot is the Z80 CPU and the voltage regulator.
The Cromemco DPU card is probably working, but does nothing useful as it does not have a serial port. I just put it inside the case to see if it did anything.
Any suggestions on what I can try to get the CCS CPU card working, and does it require to have a RAM board in the system to actually work or can it work entirely on its own ?
