I recently acquired an 8600/250. It has approx 160MB of RAM, all the VRAM banks filled and external LaCie SCSI CDROM/JAZ/HDD units. The internal SCSI HDD was removed. Problem is, the unit does not boot. The power button glows green and the fans spin up but nothing more happens. I have tried reseating all of the RAM and the CPU card. Nothing looks corroded or blown. The logic board looks ok. I have tried resetting the CUDA and the logic board. The PRAM battery still hold a charge. I also tried disconnecting the SCSI and floppy cables inside to see if I could get the bare logic board to respond. Apart from being filthy inside, it is in pretty good nick. I still cannot get a chime out of this. The previous owner assures me it booted and ran fine before he packaged it up and he had only opened it up to put in RAM in the past. I have cleaned it up as much as I can without totally disassembling the PSU but still cannot get a peep out of it. Is there anything I have missed?
