Apple iMac main logic board (MLB) schematic for project M38A at the DVT (design validation test) stage, document 051-7148, revision 13. Packed as a 2.57 MB RAR, it covers an early-stage drawing, so details may differ slightly from final production boards. The 051- prefix is Apple's schematic document number. Use it to follow power rails, check standby voltages and locate components, but compare the board markings and revision against your iMac before relying on part values.
