RAR archive with documentation for Apple logic board 820-1679, schematic number 051-6680 at revision F000. Following Apple numbering, the 051 drawing is the circuit diagram for the 820 board, useful for tracing power rails, finding where a short is pulling a line down and checking the sequencing signals. The package is about 1.13 MB, typical of a single schematic PDF. Before using it, confirm the 820 number silkscreened on the PCB, since nearby numbers belong to unrelated machines.
