Powerbook Pismo's

[Christian Kotz]

I was wondering if anyone out there can offer some advice on an issue I 
have with a Powerbook G3 Pismo 400mhz. Basically the unit crashes a few 
seconds into startup as is just when the flashing folder comes up it 
jams and that's it or if I boot from CD it sits on a grey screen. It 
boots and stays on when open firmware terminal is invoked 
(command-option-o-f) and I can continue typing etc without a problem 
but if I tell it to mac-boot it's back to the crash on first folder 
flash. Also firewire target disk mode works fine without freezing it's 
just the computer running naturally that causes the issues. I can't do 
anything with it apart from Open Firmware and Firewire target.. as I 
just freezes up and has to be forcefully shut down or reset. I've tried 
NVRAM resets, Set-defaults commands and reset-all in Open Firmware as 
well as PRAM resets, cold resets and removed backup battery/PRAM 
battery, main battery and CD module but still no improvement. Also 
wiped Hard Drive which meant the flashing folder crashed a few 
nanoseconds later than it did initially where I could only see a blank 
blue folder. I hope this kinda makes sense and that someone has some 
possible fixes they can offer. I'd like to revive this laptop as it is 
a feature packed unit :)
