RAR package for Apple logic board 820-2132 with schematic number 051-7520 at revision B000, about 1.66 MB in size. This board has several schematic variants in circulation, and this one carries the highest 051 code of the group, so matching the version to your unit is essential. Apple uses 820 for the PCB and 051 for the schematic. The drawings help trace power rails, find test points, read net names and isolate a short on a dead board. Check the PCB revision marking before relying on it.
