Boardview for Apple J223 MLB, logic board 820-01987, revision 02. The .pcb format stores part placement and net connectivity, so a viewer like FlexBV or OpenBoardView can highlight any signal, show both board sides and point to test pads, which is useful for measuring rails, finding shorts and identifying damaged components. Apple marks its boards with 820-xxxxx numbers plus a revision suffix. Make sure the -02 printed on your PCB matches, because later revisions of this board exist and may differ in layout.
