Apple logic board 820-1919 archive, paired with schematic number 051-6949 at revision Q000. The 1.49 MB size fits a full multi-page schematic, which technicians use to follow power sequencing, find test points for key rails and identify components around a short. Apple's 051- numbers denote the schematic document while 820- identifies the board, and late revision letters such as Q usually reflect production-level drawings. Extract it with 7-Zip or WinRAR and check the board number on the PCB before comparing measurements.
