I recently restored my family's old imac, which my sister took to school. I found this wire, which i assume came with the imac...
(sorry about the bad picture quality) I am pretty sure that it is a firewire to mini usb. Any idea why this might have come with my imac G3?
Yes...it would be used to hook up a FireWire device containing a four-pin port to your Mac. The most common thing with a four-pin port would be a video camera...the smaller four-pin port saves space on a small, portable piece of equipment like that.
