OK, this may be a silly question, but...

An external firewire disc with two firewire ports, 2 computers both with
firewire. I know I can connect the disc to either computer, network the
computers by ethernet and share the disc over the network. But I was
wondering....can I connect both computers to the disc by firewire, at the
same time, and use it as external storage for both devices.

Only if you never turn both computers on at the same time. Imagine if they both decide to write to a file at the same time!

The external disc is 120GB and I'm thinking of using it for backup for both
computers. If I want to be able to boot either computer from the remote disc
in either OS9 or OSX, how do I set up the disc

- is it best to set up different partitions for each OS

IMHO, yes.

- do I need different system set-ups for each computer (ie 4 in total) or
can I just set up one OS9 system and one OSX system that will boot either
computer (obviously not both simultaneously)

Computers are:
400MHz G4 Ti powerbook
800Mhz G4 15" iMac

You might be able to get away with one OS X system for both of them, but OS 9 is probably different for each of them. Which would just be confusing really!

Have fun,
Shay
