I have had boards that, on my bench, worked perfect but when the owner got it back, it was giving problems with artifacts and had to...

    Macintosh SE/30 logicboard recreation (thread revival)

    Did you get this solved? I have a board that is doing just about the same thing. I turn it on, stays good voltage on the 12v rail then after a few seconds jumps to 13.5v. 5v is good. I get no chime and no ram activity as I am using my blink ram that will blink on the RW signal. Would be great...
