Documentation for Apple board 820-1501, project Q26A, in a 1.31 MB RAR archive. The Q26 code is an Apple internal project designation, and the A suffix identifies this variant among the A, B and C packages for the same board number. The name does not list the contents, which are probably schematic pages. Use them to trace rails, locate components and diagnose shorts. Confirm the board number and variant details on the PCB before trusting part positions or values.
