Revision A documentation for Apple logic board 820-2262, stored as a 1.84 MB RAR archive. It is the earliest revision in the set, and a revision G package for the same number also exists, so compare the revision code on the board before using values or part locations. Expect schematic pages after extraction, though the name does not confirm it. They help with tracing power rails and enable signals, checking a short to ground and finding the right test points while diagnosing a no-power fault.
