Repair archive in RAR format, 1.45 MB, for Apple board 820-2491 with the internal project code K51. A companion file for the same number is labelled K51A, so check which variant fits your machine before relying on part values or placement. The included documents are not named; a schematic and possibly a boardview are the usual contents. Technicians use such material to trace voltage rails, identify the power-up sequence and isolate shorts, after confirming the 820 number on the logic board.
