Apple board 820-1984 archive containing material for schematic number 051-7039, revision M000, about 1.08 MB. The size suggests a schematic PDF of moderate length, useful for tracing rails, following signals between ICs and finding components around a fault. In Apple's scheme the 820- number identifies the PCB and the 051- number the drawing, and the revision code indicates which release the pages reflect. Extract it with 7-Zip or WinRAR and verify the PCB markings to make sure the drawing matches your board.
