Apple 820-1540 archive for the base Q45 project, the largest of the related packages at 2.38 MB in RAR format. Q45 is Apple's internal project code, and separate Q45A and Q45B variants exist under the same board number. The name does not detail the contents, so extract it to check for schematics or layout files. Such documentation lets a technician trace voltage rails, locate test points and check part values. Confirm the variant on your board before relying on component references.
