Apple schematics, boardviews and BIOS

The catalog lists 187 Apple boards with 684 files: 130 boards have schematics, 100 have boardview files and 120 have BIOS dumps.

Apple logic boards are identified by an 820-xxxx or 820-xxxxx number printed on the board, sometimes with a revision letter. The A number on the bottom case (A1278, A1466, A2179) names the model, and one A number can come with several 820 boards.

Always search by the 820 number. Boardviews for Apple boards are mostly .BRD or .BVR files, and the schematic page numbers follow Apple's own layout rather than ODM conventions.

In this catalog most Apple boards are identified by 820-xxxxx logic board numbers. Search by the code printed on your PCB if you are not sure which board your laptop has.
