Uncompressed CAD-format boardview for Apple logic board 820-03400 revision A, 2.14 MB in size. Since it is already extracted, it can be loaded directly into a viewer such as FlexBV or OpenBoardView. There you can search parts by designator, highlight nets and locate test points while diagnosing shorts or missing rails. Apple's 820-xxxxx code is silkscreened on the logic board, so confirm the number and the revision letter before relying on component positions.
