Apple A1311 package for project K60, logic board 820-3126 revision A, compressed into a 1.84 MB RAR. The A-suffix marks the board revision, which should match the marking on your PCB. Apple uses 820- numbers for logic board part numbers, making them the most dependable match for schematics and boardviews. Use the contents to trace power sequencing, measure standby rails and find shorted components. Extract with WinRAR or 7-Zip and confirm which documents are included before you start probing.
