Fortified with ample coffee I went out to do further battle with the recalcitrant 9500 this am. Thinking it may have cured it's own ills overnight I tried to boot; no luck. Removed the Ram stick in B6 thinking it may have gone bad and tried to boot; no luck. Dug out the extra MLB, installed all the Ram, checked Pram battery voltage, etc and tried to boot; no luck. Then pulled all 12 Ram sticks and tested them in pairs in the 8600/G3 and all tested good. At this point I figured the G4 card had gone bad but reinstalled the Ram, installed the SCSI and video cards and tried one more time and,voila! it booted. To be sure there were a couple of issues but a little fooling around took care of that. Launched ASP and tried to scan the devices; complete lock up. Unplugged the power to the CD drive, rebooted, launched ASP, scanned the devices with no problem. Then plugged CD drive power back in, scanned devices in ASP with no problem. Shut down the 9500 while muttering darkly about gremlins and magic, gathered the better half and the dogs and went for a hike in the hills.

Quite frankly, I don't know what was going on but hopefully it's back to normal.
