Small Apple boardview for the J230 RIO board 820-01992, revision 01, marked as version v7. RIO usually refers to a secondary input/output daughterboard rather than the main logic board, so this file covers that separate PCB only. A boardview viewer shows connector pinouts, part locations and nets, helping when a port or peripheral fails and the fault must be traced across the flex link. Confirm the 820 number and revision printed on the small board, and pair it with the main board files for full signal paths.
