Apple 820-01055 logic board location map, revision 07, with the name also marking it as an MLB EVT drawing dated or coded 0307. EVT normally means engineering validation test, an early pre-production build, so some placement details may differ from retail boards. The PDF maps reference designators to their physical position, useful when finding a part named in the schematic or locating a test point. Verify the revision on your PCB and cross-check with a boardview before replacing components in tight areas.
