Power Mac g4 Manuals?

First link I tried after creating an ID gives me a non existant link. My tenant left a Powerbook G4 with ATI graphics board, 40GB HD and 256 MB memory.

I added 1X 256 and 2 X 128 tried adding a 60GB HD.

I have no further information on the equipment. I realize I need to format the drive for Apple but the only software I have is what is on the existing HD which has had some damage.

Should I just forget about trying to resurrect the system?

Last time I worked with Apple was mid to late '80's.

Have lots of PC equipment.
