Apple logic board archive for 820-1940, carrying schematic number 051-7001 at revision D000. The 1.39 MB RAR most likely holds the schematic PDF for this board, used to trace power rails, follow signal paths and identify components when diagnosing a dead or shorted board. Apple pairs each 820- board number with an 051- schematic number, and the revision letter matters because component values and layouts change between releases. Confirm the 820 number silkscreened on the PCB before relying on any value, and extract it with WinRAR or 7-Zip.
