….but the CTO version (whatever that acronym means) has a SCSI hard drive; SCSI drives are not compatible with Target Disk Mode.
Neither do I know what that means. I did a search for specs using the serial number and got a sheet which used CTO in four places:
Model: Power Mac G4 (AGP Graphics) (CTO)
Installed RAM: CTO
Hard Drive: CTO
Optical Drive: CTO
As for Ethernet, you'd have to have had File Sharing enabled on the G4, but there might be other issues trying to access OS 9 files from a Mountain Lion Mac. Google doesn't have much to say about the topic...
I have no idea whether File Sharing was enabled, and OS9 was just a guess on my part. The machine belonged to a daughter ( who thinks Dad's attic is a great indefinite-term storage facility). She may have installed a later OS as the machine is good up to Tiger.
