Apple logic board 820-2110 with schematic number 051-7229 at revision H000, delivered as a 1.44 MB RAR archive. The H revision suggests a late iteration of the drawing, so values and parts may differ from earlier copies of the same schematic. In Apple numbering 820 identifies the physical PCB and 051 the schematic document. Technicians use it to trace voltage rails, follow enable and power-good signals and find test points when a board will not power on. Match the PCB revision before use.
