I have an old Power Mac G3 266 Mhz that, originally didn't have any USB ports. I upgraded the G3 to a 500 Mhz processor and added 2 USB ports. Note: there is no Fire Wire on this old G3. Now, I just bought an iMac G5 20". Here's the question: How do I transfer all my important files from the G3 to the iMac G5?? Do I have to buy an external hard drive that has SCSI connectivity, and then transfer the files from A to B to C? Or, is there any other way to do it? Please keep in mind, I am not a techie, so keep it simple! Thanks!!
