I have a Power Mac G3 Beige Tower running OS 9.1 and I'm wondering if there's an easy way to transfer files from my PC running either Win 7 or Linux (whichever works better for this). The G3 has ethernet so I'm assuming I can do this over my network somehow, but I'm not sure how. I also have a G4 Powerbook running OS X that I can use for this if that's easier.
