Archive for Apple logic board 820-00163, with X425G in the name, which appears to be the Apple project code, and a trailing 05 whose meaning is not stated. The zip is 4.37 MB and does not list its contents, which may include a schematic, a boardview or both. Use it to trace rails, locate parts and diagnose no-power or short faults. Make sure the 820 number and any project code on your board agree with the documents before relying on component values or pinouts.
