    I have created a helpful diagram to assist others (and myself!) in replacing capacitors on a Macintosh SE/30 motherboard, as the aged electrolytic capacitors often leak fluid onto the motherboard and cause many issues, requiring replacement.

    I would like to include the basic function of each capacitor (e.g. audio filter, analog to digital converter buffer, power decoupler, etc). There's only 13 in total so it shouldn't take long.

    What should I do? Attach all the Apple and BOMARC schematics with some basic hints on where to find the ones I'm after?

    Shouldn't take even an hour. I just have very little clue about what they do -- all I see is some circuit paths, a capacitor with a link to ground.
