Location map PDF for the Apple 820-01055 logic board, revision 07. The placement drawing shows where each reference designator sits on the board, letting a technician jump from a part found in the schematic to its physical location when probing rails, checking a suspect capacitor or replacing a burnt component. Apple numbers its own boards in the 820-xxxxx format, with the two-digit suffix indicating revision. Match the -07 marking printed on your PCB, as component placement can differ between revisions of the same board.
