Schematic archive for the Apple logic board 820-1577, identified by drawing number 051-6888 at revision B000 and packed as a 1.12 MB RAR. Apple pairs the 820 board part number with a separate 051 schematic number, and several drawings exist for this board. The contents are not listed, but this size suggests PDF circuit pages for diagnosing missing rails, tracing signal lines and checking component values. Match the board revision before use, as drawing differences can change part numbering.
