Minecraft wiki entry for Morse_code, associated text: To build the reseter, you need to just place redstone torches under all the rs-nors and then have a repeater 'and' gate the requires more than a dash would and set up a button for that, it is would recommended to use a delay after the gate as well to make sure that no other things will change when you send the reset through the system. Also remember that you want the lights to be OFF, default and then turn on when you want to reset.
