You could add the 7300 to your network and share the HD on it. Once booted, it would not require a screen.
Then you could dump stuff to it over the network.
Without Firewire there is no way to make the 7300 start in Target mode and appear on the desktop of your G4

Is there a smart way to use my redundant 7300 as backup disk for my G4? Controlling them both from one screen and having the 7300 appear automatically when I switch on?
