Yes, that's right. My son just bought a 631CD today to tinker with (he has an iMac G5 20" at college). I never was into Macs back then, but didn't the older Macs use AppleTalk or some such? Did they use ethernet or some other connection method? How would I go about connecting (if possible) to the iMac for file transfer and internet? I think it is running some version of System 7, and the CD doesn't seem to work (from what I can tell, which isn't much). How can I tell if the machine "sees" the CD drive? Any help is deeply appreciated.
