Apple 820-1889 archive with schematic number 051-7173 at revision G000, marked as project M42C, about 1.26 MB. It is one of several drawings for this board number across M42 project variants, each with its own schematic number, so it is not interchangeable with the M42A or M42B files without checking. Technicians use these pages to follow power sequencing, locate shorted rails and identify components. Unpack it with WinRAR or 7-Zip and verify the board before trusting part values.
