    Default Amiga 4000 from scratch

    Hi
    This weekend I started the arduous task of transplanting the components of a motherboard from my A4000 to a new replica motherboard.
    Being a hobbyist and not a professional, but so far things are going well.
    I have to keep thinking positive and think I can do it.
    So far I have already completed the bottom of the plate and started the top.
    The biggest difficulty was the connectors, with so many pins to unsolder.
    In the end, maybe it works ...

    Good luck riri you are a braver man than most.

    I was lucky enough to have John "Chucky" Hertell transplant a busted A4K motherboard to a red Acill PCB like yours. maybe contact him if you run into any issues

    Hi
    Now in the final stretch, I'm waiting for the socket of the super buster and some resistors.
    It has not been very easy, but not impossible to achieve.
    Next week will be the result test...
