Schematic archive for the Apple A2681, supplied as a RAR containing PDF documentation for board 820-02536. Apple marks its logic boards with 820- numbers, so this file covers the board associated with that model. A technician uses it to trace power rails, locate shorts on supply lines, follow signal paths and identify components and test points. Extract it and open in a PDF viewer, ideally alongside a boardview. Verify the 820-02536 number on the PCB before following its values.
