      correct, but            01/01/70 00:00      
         I was assuming...            01/01/70 00:00      
   Bounce time of your relays?            01/01/70 00:00      
      Not very clearly            01/01/70 00:00      
         Bravo!            01/01/70 00:00

      HUH?            01/01/70 00:00      
         I am sorry            01/01/70 00:00

            Design is a state function            01/01/70 00:00      
               All the more using shift registers!            01/01/70 00:00      
                  I think your solution is better            01/01/70 00:00      
                     I guessed so...            01/01/70 00:00
