Boardview for the Apple 820-00939 logic board, labelled with the J174 project code, supplied as a .pcb layout file of about 2.3 MB. It shows the physical placement of every component, the nets each pad belongs to and the test points, which makes it the practical companion to the matching schematic when measuring diode readings or locating a shorted capacitor. Files of this type are normally opened with boardview viewers such as FlexBV or OpenBoardView. Check the 820 number silkscreened on the PCB before relying on part positions.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @ShareMan_Electronic_Files. Enginerys does not host this file.
