7100/66 - Battery blew up. Took out the motherboard, ruined case metal. Demanufactured 12/9/2008.

7100/80 - Just won't boot. Tried new: PRAM, ROM, Video Card, PSU.

Near death:

7100/66av - Boots, poor chime, sound, bad caps. Old failing HD.

7100/66 - No chime, boots, no sound, bombs during boot.

The 66av may be repairable with a cap job, maybe the other one as well. The battery one was a total loss for the case, mobo.
