RAR file for Apple logic board 820-1875, naming schematic number 051-6929 at revision C000 plus an extra reference 399027. In Apple numbering, 820 identifies the printed board and 051 the matching schematic, so this is most likely a circuit diagram set. Repair technicians use such drawings to look up rail names, check the expected voltages and find which components feed a shorted line. The C000 revision is an early release, so confirm the board marking and watch for differences against later production boards.
