    • The Power Mac G4 MDD: the last, and the fastest G4-based Mac. This computer boasted up to a Dual 1.42GHz PowerPC G4 CPU (though I have a single 1.25GHz).

    • Two USB 1.1 Ports

    • Assorted Audio

    • Video (ADC & DVI)

    • Networking (RJ-45 Ethernet/56k Modem)

    • Some later model MDD's (such as the dual 1.42GHz) Have a FireWire 800 Port Here:

    • Once the cables are free, set the drive cage aside.

    • To remove the hard drives from the cages, remove the four screws on the sides of the cage that are connected to the drives, then slide the drives out.

    • The two cages are cross compatible and can be put in either location.

    • The MDD does not have a 128GB drive limit like older Macs. My MDD has 3 drives (a 400GB Hitatchi Deskstar, 40GB Seagate Barracuda 7200.7, and a 30GB Quantum Fireball LCT).

    • Note the ID jumpers on the two drive set. One is set to Master, the other to slave. A single drive can be set to Cable Select.
