Apple schematic, or circuit diagram, for logic board 820-01958 with X1783 and j230 codes; this copy does not state a revision and is a different size from the -02 version. The PDF documents rails, signal paths, connectors and component values, letting a technician follow a failing supply back to its regulator or understand a sequencing problem. Read the revision from the title block inside the document and compare it with the marking on your board, since nets and parts may differ between revisions.
