This is the connector on the back of the console that the ac adapter plugs into. Some of these connectors have 4 pins, while others have 3. The newer power supplies (QI) only have 2 pins. They way they were set up you can use any ac adapter with any of the consoles.
	The AC voltages in are: 1. Black 8 volt 2. White 16 volt 3. Red 5 volt 4. No connection

The power supply is a very standard setup, and could be replaced by any standard PC power supply.
	The DC voltages out are: Pin 1 = -5 volt Pin 2 = +12 volt Pin 3 = GND Pin 4 = +5 volt.
