Boardview for the Apple 820-00034 logic board, revision A, in BRD format inside a compact 94 KB RAR archive. The 820 prefix is Apple's logic board numbering and is printed on the PCB. BRD files open with OpenBoardView, FlexBoardView or Boardviewer, showing component locations, net names and test points. A companion schematic names the board J117, useful for cross-reference. Use it to find shorted rails, locate tiny components and measure diode readings, after confirming the 820 number and revision.
