Full circuit diagram for Apple logic board 820-01814, with the name SAFFORO attached, as an 11.2 MB PDF schematic. It covers power rails, the power sequencing chain, and signal connections, which you need when diagnosing a board that will not power on or a shorted line. Use it together with a boardview to find physical locations quickly. Check that the 820 number and dash revision on the board match before trusting component values or net names.
