    I have one of these installed in a Transporter pinball, it will not boot.
    I have the PIA light and the 5v light on solid fron turn on. Does anyone have one of these fitted and can give me a clue as to what these lights mean. I would have expected the Pia light to be a test, then turn off and the blanking light to come on with the 5v light remaining on.
    There are no instructions, repair guides or schematics for this board that I can find.
    Does this indicate a PIA fault on boot?
    Thanks, Ray

    Resolved.
    Faulty CPU 6802 at U24.
    The standard System 11 repair guide gets you to probe this CPU for signals anyway so Rottendog schematics not needed in this case.
