Apple 820-1599 documentation for project Q59A, delivered in a 1.28 MB RAR archive. Q59 is an Apple internal project name, and the A suffix marks the first listed variant of that design. The archive name does not describe its contents, so open it to see whether it holds a schematic, a boardview or both. Typical uses are tracing voltage rails, finding the parts behind a short circuit and reading signal names. Check the PCB markings against this variant before trusting component positions or values.
