Very small 12.4 KB RAR for Apple 820-2309, also carrying 51-7500, A000 and IR in the name. The 51 number follows Apple schematic numbering, A000 looks like a revision code, and IR points to an infrared receiver daughterboard. Given the size, expect a single short schematic or drawing. It is useful for checking the IR sensor supply, its signal line and the connector or flex back to the main board. Confirm the board number on the PCB before relying on it.
