As documented below, /RESET on the USER port shorted to GND will cause
a hardware reset.

On early C64s you can also use the serial (disk drive) port to reset the
machine. Later C64s have a buffer there and it no longer works.
/RESET to GND again:

Many C64ers have momentary switches mounted to their cases and wired to
the backs of the USER port header for this purpose.
