Archive tied to Apple logic board 820-1501, with the name noting the internal project code Q26. The file name does not say whether the RAR holds a schematic, a boardview or firmware, so open it and check the contents first. Apple uses the 820-xxxx pattern for its own logic board part numbers, printed on the PCB near the edge or under components. Confirm the number on your board matches before tracing power rails or comparing signals, since neighbouring 820 numbers can be quite different designs.
