Apple Lisa DataPower Power Supply Schematic (reverse-engineered)
The Apple X/Lisa "DataPower" Power Supply schematic is a two-sheet drawing of the DataPower supply used in the Apple Lisa and Macintosh XL, revision B, dated 12 January 2002. It was reverse-engineered from the boards; Apple did not issue it. The drawing's own notes say to use it at your own risk.
