Apple 820-1600 logic board documentation archived as RAR, tied to schematic drawing 051-6570 with revision B000. The 1.06 MB file likely holds the circuit diagram pages, although the name does not spell out the contents. Apple uses the 820- prefix for the board part number and the 051- prefix for its schematic drawing. Use it to check component values, trace rails back to their regulators and spot test points, but first make sure the board in hand matches this drawing and not one of the other 820-1600 variants.
