Apple 820-2101 repair archive in RAR format, labelled with schematic number 051-7225 at revision B000 and weighing 1.65 MB. Several schematic numbers exist for this board, and this one carries the lowest 051 code of the group, so matching it to the PCB revision matters. Apple 051-series documents are typically multi-page PDF schematics used to trace voltage rails, identify the parts on a net and find measurement points. Extract with any RAR-capable tool and verify the board marking before measuring or replacing components.
