RAR archive of roughly 1.5 MB for Apple logic board 820-2056, carrying schematic code 051-7155 at revision A000. The A000 suffix marks an early drawing revision, so later production boards may differ in component values or placement. In repair work such a schematic is used to trace power sequencing, read net names, find test points and work out which component pulls a rail to ground. Extract it with a standard archiver and confirm that the board number and revision on the PCB match before relying on it.
