RAR archive for the Apple logic board 820-1881, with schematic number 051-7099 at revision H000 given in the name. Apple labels its boards 820-xxxx and the matching schematic drawings 051-xxxx, so the archive most likely holds the schematic set for this board. Technicians use such drawings to follow power rails, find the source of a short and check signal paths between chips. Compare the 820 number silkscreened on the PCB before relying on it, and note that the H000 revision may differ in small details from other revisions.
