Boardview for the Apple MacBook model A1989, logic board 820-00850 revision A, provided as a 201 KB RAR archive. The name gives the BDV designation together with a BRD extension, a layout format that OpenBoardView, FlexBV and similar viewers can open. Apple uses the 820-xxxxx pattern for its logic board part numbers. Technicians use the view to find components, probe points and connector pinouts when diagnosing power rails or shorts. Pair it with the matching schematic and confirm the 820 number printed on the board.
