I recently acquired 8600/300. It powers on but doesn’t have chime or video. Any idea where should I start to troubleshoot this. I did replace the PRAM battery. Last 2 pictures are of the processor.
Try 2 things. If you have a spare PCI GPU (like a Mach 64 or Rage 128 for Mac) try booting with a graphics card installed. DB15 can be weird at times. It could also be picky/bad/dirty RAM. Remove the RAM modules, clean all of the RAM slots (cotton swabs soaked in 91% rubbing alcohol works fine), clean the module's contacts, and reseat the RAM.
I will have to check if have pci gpu. I think I have one in G3. I did remove the all the RAMs cleaned with WD-40 contact cleaner. No change. I even did cuda reset.
Try the contact cleaner in every slot, reseat everything. Contact cleaner inside every socket and on every SIMM/cards + scrubbing with a Q-tip every edge pin connector.
Agree with @MrFahrenheit the little knobs in the CPU card are probably important. Having a spare CPU card does help when diagnosing these machines.
CUDA is weird too, I think these machines are CUDA. Have to reset before you might get a chime/video.

The issue is compounded with this being a Kansas board. From what I’ve read you cannot use earlier CPU cards in a Kansas board, you must use Kansas generation and above only.
Finding a Kansas + CPU card could be difficult, unless it’s another accelerator.
I tested the above card in 7500 and it booted fine at 200Mhz. 7500 has SoNNeT Crescendo PCI G3 500 MHz Upgrade Card. When test this card on 8600 i am getting nothing. I did do Cuda reset each time i swapped cards.
