PDF schematic for the Apple 820-2110 logic board, drawing number 051-7229 with revision code 33000, an alternative issue of the same design as other 051-7229 copies. The diagrams show power sequencing, rail names, connector pinouts and component references that a technician needs when diagnosing no-power or no-boot faults. Any PDF reader opens it, and searching net names makes tracing quick. Compare it against the other revision if values look off, and confirm the 820-2110 number on your board first.
