    Hello community,

    I have a beautiful G4 PowerBook, 1.5Ghz with a bad motherboard. I am hoping to replace the mobo with a 1.67Ghz that I am sure works, from a VERY similar model. Would this be possible, or am I out of luck?

    Bad motherboard-
    1.5 Ghz
    Model: PowerBook 5,6

    Good motherboard-
    1.67 Mhz
    Model: PowerBook 5,6

    Follow up question- I know it is possible to test the power trickle in the motherboards of G3's to determine whether or not they are working. Is there a similar test to run on these motherboards? Thanks.
