Archive for the Apple logic board 820-3588 at revision A. The name does not say what is inside or which Mac model it serves, so open the RAR and check whether it holds a schematic, boardview or ROM image before planning work. At 1.52 MB it could contain documentation or firmware. Apple uses 820-prefixed numbers for logic boards, with the letter marking the revision. Compare the number on the PCB carefully, as neighbouring numbers belong to entirely different machines.
