I need to purchase a Firewire cable to connect an eMac to an iMac. (Here comes the reason I'm apologizing in advance.) Can I just buy a Firewire cable at Target or Radio Shack? Are Firewire cables pretty much standardized now (6 pin to 6 pin?) As you can tell, I have no firewire experience. USB and MIDI, yes. Firewire, no.
