RAR archive for the Apple logic board 820-1600, labelled with schematic document number 051-6770 at revision B000. At roughly 1.05 MB it most likely holds a schematic set in PDF form, though the name does not list the contents. Apple numbers its boards with the 820- prefix, while the 051- number identifies the schematic drawing itself. Confirm that the 820 number silkscreened on the PCB matches before tracing power rails, signal paths or component references, because revisions can differ in parts.
