Apple 820-1881 logic board set with boardview file and schematic diagram, and according to the name the IO boards are included too, making this the largest archive in the series at 7.68 MB RAR. Having the IO board documents helps when faults involve ports, connectors or flex links between boards. The schematics let you trace rails and signals across the boards, while boardview layouts, opened in OpenBoardView, FlexBV or similar, show component locations and test points. Match the 820 numbers on every board before relying on the data.
