Schematic package for Apple logic board 820-01958, project X1783 MLB-TKSB, that according to the name also includes a silkscreen layout view alongside the circuit diagram, all as PDF in a RAR archive. The silk drawing shows the physical position of components, which helps when no proper boardview is available. Combined with the schematic, it lets a technician trace rails, locate parts and find measurement points. Apple's 820-xxxxx code must match what is printed on the board, together with the revision, before relying on part placement.
