RAR archive for an Apple J45 main logic board at the DVT stage, board 820-3662 with schematic number 051-0456. Apple uses 820- for the PCB part number and 051- for the matching schematic drawing. DVT, Design Validation Test, is pre-production, so minor differences from retail boards are possible. The 1.68 MB package likely contains the schematic set for tracing rails, finding parts and diagnosing shorts. Verify 820-3662 on the PCB before following measurements.
