   Any way you want to. The C64 RESET line is driven by an open-collector 
buffer, so all you have to do is make an electrical connection between pin 3 
and pin 1. Many users have drilled holes on their C64 cases and installed 
normally open pushbuttons (I tend to use a toggle switch in series as a 
safety). Holding the button down for even a couple of microseconds will 
trigger a reset.
