Sounds straightforward.

Have you ever? Was this machine set to boot into Open Firmware? Were the 
input and output devices set to stta?

On the G4 end, you have RS422, so it's not as simple as pulling the TxD 
and RxD lines. Your cable should take care of that, though.

Plug in a monitor. If it comes up, reset the input and output devices. If 
not, zap the pram and try again.

Why would it need salvaging?
