Schematic archive for Apple logic board 820-1747, drawing 051-6772 at revision E000, marked with internal project code Q45D. A separate Q45C release of the same drawing exists, and the project codes distinguish product variants built on one board design. At 2.26 MB the package may hold more than a single PDF. Technicians use it to trace rails, check the power-up sequence and locate parts near a fault, but should confirm both the 820 number and the machine variant first.
