Okay, I'm unclear on the concept and would appreciate any help. 1. I'm transferring data from a G4 eMac to an Intel (white) iMac. The eMac has Firewire 400 and the iMac has Firewire 800. Which cable do I need? 4, 6, 8 pin? 2. I'd also like to transfer from data from a friend's old iMac G3 400 mhz to the G4 eMac. System profiler doesn't seem to indicate what the Firewire "speed" (if that's the correct term). Which cable would I use for this? Thanks very much.
