Re: A86: Theory question [i think its about time we....]
all of the games still work and all of the grayscale still work it's just
that every thing is much much faster...i didn't see any need for it as i
don't play games, but if you wanted you could just hook a little dip switch
to the two pads where you removed the original capacitator from that turns
on and off the 22pf (is that the original) capacitor to switch between fast
and regular modes to slow it down for the old games.
