RAR archive covering Apple logic board 820-1577 with schematic number 051-6338 at revision C000, about 1.11 MB. The 051 code is Apple's drawing identifier and the suffix gives the drawing revision, while 820 marks the board part number. The contents are not stated, but this size fits a set of PDF schematic pages. Technicians use these pages for rail tracing, short hunting and checking signal connections. Compare the board marking and revision before relying on part designators, as other drawings exist for this board.
