Nintendo Color Inversion Circuit    by  Paul Kahler <phkahler@oakland.edu>
--------------------------------------------------------------------------
This circuit is used to invert the color signals from old nintendo games
so they may be used with standard (ie not Nintendo) monitors. One of these
must be constructed for each of the RGB signals. The only drawback is that
it requires a -12V supply (my cabinet has that anyway).
