Powering the SNES interface
The SNES interface must power the controllers with +5v. This can either be sourced from the parallel port
or from from the keyboard, joystick or USB interfaces.
Single SNES controller
A single SNES controller can be powered directly from the parallel
port. Simply add the following components to any of the interfaces:

The connections in the diagram is in addition to the normal interface wiring. If all
this sounds confusing - build the SNES interface like it is shown on the DirectPad Pro page:

Multiple SNES controllers
The parallel port should not be used to power more than one SNES controller. +5v for the SNES controllers
can be sourced from many places, including the joystick port, keyboard port, USB port or harddrive power
cable. You can also use a 7805 regulator with a wall adapter or battery.
NES PowerPad controllers
The controller (reportedly) uses a lot of power and should not be powered from the parallel port. +5v can
be sourced from many places, including the joystick port, keyboard port, USB port or harddrive power cable.
You can also use a 7805 regulator with a wall adapter or battery.
