Archive for the Apple IR board numbered 820-2155, the small daughterboard handling the infrared receiver, packed as a 218 KB RAR file. The name gives no schematic number or revision, so check the 820 code on the PCB before use. Material like this is useful when a remote stops responding or the sleep indicator misbehaves, letting the technician trace the IR sensor supply, the signal line and the flex or connector to the logic board. Open it with WinRAR, 7-Zip or a similar archiver to see the included documents.
