RAR archive of 291 KB holding the boardview for Apple logic board 820-03400, revision A, in CAD format. Unpack it with WinRAR or 7-Zip, then open the extracted layout in a boardview viewer such as FlexBV. It gives component placement and net connectivity for diagnosing shorts, missing voltages and damaged connectors. Apple's 820 numbering is printed on the PCB, so compare it with your board before measuring. The contents should match the ZIP and the standalone .cad versions of the same layout.
