Documentation package for Apple logic board 820-3588, revision A, in a 1.52 MB RAR archive. The name does not state the computer model, so identify the device by matching this 820- part number, which Apple silkscreens on each logic board. Files like these normally carry a schematic and sometimes a boardview, used for tracing rails, checking the power-up sequence and locating test points. After extracting, look at the title block to confirm the model and revision before relying on component values.
