Power Macintosh Logic Board Diagram

There are five versions of the Power Macintosh 7200 logic board: one 75 MHz version, two 90 MHz versions, and two 120 MHz versions. The two 90 MHz versions of the logic board are functionally equivalent, as are the two 120 MHz versions; However, one of the 90 MHz versions and one of the 120 MHz versions has an auxiliary fan that connects at J70.

Important: Do not unplug the Peltier device (one red wire and one black wire) that runs from the processor to the logic board or you will damage the board.

The following drawing shows the Power Macintosh 7200 logic board. Refer to the parts chapter for information on how you can distinguish between the different logic boards.
