Component placement drawing for Apple logic board 820-01055, a 228 KB PDF. Placement sheets map reference designators to physical locations, so you can find a capacitor, IC or connector named in the schematic without a boardview program. The 820-xxxxx format is Apple's logic board part numbering. Use it while hunting a short, replacing a damaged part or checking test points, and confirm the 820 number silkscreened on your board matches this document.
