Apple 820-1600 logic board documentation under schematic number 051-6809, revision B000, packed in a RAR archive of about 1.05 MB. It sits alongside the 051-7201 drawing for the same board, and the two may differ by product configuration or release date. The diagrams help follow supply rails, identify regulators and their enable lines and isolate a short to ground. Verify the board number printed on the PCB before relying on values, and check the other drawing if something does not match.
