Hi guys...this is a wierd one. I have just rebuilt a G4 MDD. Works great, except for one thing. I cannot get the Cd drive to open!! Pressing the eject button on the kyb doesnt do it. The eject button on the actual drive is covered by the plastic tab of the mirror metal. The new Itunes doesnt have an eject button that I can see, either. I dont see any "eject disk" button in any of the utilities. Someone told me that the jumper for "cable select" has to be ON for any of the kyb commands to work>?>> Guys , have any ideas? thanks so much Retro.
