Yes, Stewie that's my drill also, I just think maybe because all my cubes were somewhat used that maybe the logic boards are a little fuzzy. But the AHT and all the other stuff I have for testing always say OK, and I have a lot of different flavors:-) BTW thanks for the firmware info for my Cube1.2 it's a blast of a machine. I'd like to find someone who does board level repair of my PM G5 FW ports.
