Compressed RAR package for Apple board 820-1881 that references drawing number 051-6941, revision 07001, and the internal project name MULLET. Apple pairs 820 board numbers with 051 schematic numbers, so the contents are probably circuit diagrams for this logic board. A second drawing number for the same board suggests an alternative or earlier document release, so compare it with the H000 set when values disagree. Use it for tracing supply rails, checking the power-on sequence and locating suspect parts, after confirming the PCB marking.
