Archive covering Apple 820-2054 with schematic number 051-7150 at revision A000, about 1.87 MB. It is an earlier or alternate drawing compared with the 051-7270 B000 file for the same board number, so compare both carefully if values differ. Technicians typically use these pages to trace power rails, check signal paths between chips and find components near a suspected short. Unpack it with any RAR-capable tool and match the board number and revision on the PCB before relying on part values.
