Apple board 820-1888 archive for schematic 051-6950 at revision R000, 1.57 MB compressed. The size suggests a complete multi-page schematic, the main reference for tracing power rails, reading power-good chains and locating parts near a fault. A late revision letter like R usually indicates a mature drawing, but the board you have must still match. Apple pairs the 820- board number with an 051- schematic number. Extract it with 7-Zip or WinRAR and check the PCB markings first.
