They are very valid points.
It was running OS 9.2.2 until the HD began dying as it had bad blocks
and a tendency to lock up as if over heated. I then booted from
another OS X volume through firewire. It was running fine but then I
restarted and the OS X spun it's volleyball while loading the desktop
and crashed so I shut down the laptop (force shutdown-10 second power
press) tried restarting from OS X installer disc and I think at that
point the issue began. I just got a grey screen so I put the old HD in
and tried booting from OS 9 installer CD for Powerbook.
Assuming you have the correct OS9 Installer for your Pismo PowerBook
I would remove the 3.6v Pram Battery , and the main Lithium Battery ,
and disconnect the power from the hard drive if you can. If you
cannot, remove it altogether
Operate the Cuda Switch ( assuming it has one, most macs do )
Disconnect the Power and let it sit for at least an hour
Then reinstal the 3.6v pram battery and reconnect the main battery
and finally Zap the Pram whilst trying to start from the Installer CD
I think it will take some time to start up as it will need to do some
internal rebuilding after the
Cuda and Pram Zap
This should prove whether you have CPU problems after your previous
actions.
If the CPU is Ok it should start and run off the Installer disk. Take
it from there.
If you get nowhere with this action you may need professional help.
Have fun

Still grey screened. I restarted to let it boot from HD and expected
the temporary flashing folder as it wasn't the selected boot volume
but instead I got a blank folder as if the 'blessed' image were about
to flash on it but is froze before displaying it. After erasing
internal HD and zeroing data the blessed image appears on folder then
machine crashes. I also tried a set-env boot device string in open
firmware that I copied off the internet from another Pismo user but I
don't think it did anything. Its firmware is 4.1.8 I believe. I don't
have Disk Warrior but judging by the rejection of all other CD's I
don't think it will boot it. I hope that allows for a better analysis
of my situation

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
:)

Christian,
You say nothing about the OS you are trying to start up from !
When it was running, what OS was it running ?
What firmware does it have ?
What OS on the CD you are trying to start from ?
Will it start up from DIsk Warrior ?
