Compressed archive for Apple logic board 820-1502 with drawing number 051-6425 at revision B000, about 1.27 MB in RAR format. Apple's 051 numbers identify schematic drawings, separate from the 820 board part number. The name gives no contents list, but PDF schematics are the most likely payload at this size. Technicians rely on such drawings to trace voltages, locate components and confirm connector pinouts. Verify the board marking and revision first, as other drawings cover this board.
