Zip archive tied to Apple board number 820-2330, 1.85 MB in size. The name carries no model name, revision or file list, so open it to see whether it holds a schematic, a boardview or both. Apple 820 numbers identify the logic board itself rather than the Mac model, so the same model can use several boards. Match the number etched on the PCB before use. The documentation helps with rail tracing, test-point lookup and fault isolation on no-power, no-charge or no-video boards.
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 @notebookschematic. Enginerys does not host this file.
