Boardview in BRD format for Apple board 820-00597, revision 05, carrying the internal project code J134 and a DVT tag indicating a design validation test build. Apple numbers its logic boards in the 820-xxxxx form, and the suffix after the dash denotes the revision. Open the file in FlexBV, OpenBoardView or a similar viewer to locate components, follow nets and probe test points while diagnosing power faults. Check that the number etched on your logic board matches, since revisions can differ in layout.</description>
