Very small RAR archive, just 17.8 KB, for the Apple IR board with part number 820-2151. At that size it likely holds a compact document or a single page rather than a full schematic set, and no revision is stated in the name. IR daughterboards carry the infrared receiver used by Apple remotes, and diagnosis usually means checking its supply voltage, signal output and the cable to the main board. Match the 820 number printed on the PCB to the file before relying on any pinout or part reference.
