Directional pattern PDF for the Apple 820-01055 logic board, revision 07. The name suggests a drawing showing component orientation, such as pin-one marks and polarity of chips, diodes and capacitors, which matters when reinstalling ICs or replacing polarised parts after reballing or liquid damage. At about 3.45 MB it is likely a detailed image-based layout. Confirm the -07 revision printed on your board first, since part positions and orientation can shift between Apple 820-series revisions.
