Schematic archive for Apple logic board 820-1688, drawing 051-6694 at revision G000, about 1.24 MB in RAR form. Apple uses the 820 prefix for the board and 051 for its schematic, so expect circuit diagrams with net names, component references and rail voltages. Technicians use these to trace a missing supply, check enable lines and pin down shorted capacitors. Make sure the board in hand carries the same 820 number, and remember that other revisions can differ in a few parts.
