Apple archive for the A1278 model with logic board 820-3115, revision A as given in the name. A1278 is the 13-inch MacBook Pro unibody model number, and Apple's 820-xxxx numbers identify the logic board itself, which matters more than the model since one model spans several boards. The 1.80 MB ZIP contents are not listed; it likely holds a schematic or boardview for tracing rails, checking shorts and locating test points. Read the 820 number on the PCB to confirm a match.
