Apple A1989 package for logic board 820-00850-A, a 12.2 MB Zip archive whose contents are not described in the name. The A1989 is a 13-inch MacBook Pro with Touch Bar, and the newer 820-0xxxx numbering with an A suffix identifies the board and revision. The size suggests schematic and boardview material, possibly with firmware. Use it to trace power rails, locate components and check shorts on the dense board, and verify the number printed on the PCB before applying values.
