Archive for Apple board 820-1947, schematic 051-7007 with revision string 00007, tagged GOATEE and M1-M9, about 221 KB in RAR format. Goatee appears to be an internal Apple code name, while M1-M9 may indicate a page or module range, though the name does not confirm it. A near-identical copy exists without the M1-M9 tag, so compare both. Use the schematic to trace power and signal paths and locate test points, after checking that the 820 number on the PCB matches.
