Hi Bill,

Don't know about the PRAM battery - however you can certainly run OS9 on a
much more modern (relatively) machine.

If you actually need to boot into OS9, I think the G4 machines would be the
last, if you are happy to run OS9 as Classic you could go to a G5 machine
running (I think) up to OS10.4 (Tiger) and still run Classic.

There is some discussion here:

You should be able to pick something up pretty cheaply.



HTH


Cheers



Neil
