	I was trying to say 87C752 and not 87C572. It must have been a typing error. that was not the issue, the issue was the 16 I/O pins when even a standard '51 has 32. I stated (did not even look for a '572) "what do you mean, a 'standard' '51 (and the 572 at least ) have 32 I/O pins. If you are in a pin crunch and use external memaory, you goof." Erik

   You don't need these slave micros              01/01/70 00:00
      yes, but some more questions              01/01/70 00:00
         Not scary at all...              01/01/70 00:00
            In that case.....              01/01/70 00:00
            here is the schematic              01/01/70 00:00
               I would try shift registers              01/01/70 00:00
               just a note              01/01/70 00:00

      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
   The original question              01/01/70 00:00
      What's wrong with the shift register sol              01/01/70 00:00
      HUH?              01/01/70 00:00
         I am sorry              01/01/70 00:00
            that was not the issue              01/01/70 00:00
   why oh why oh why oh why              01/01/70 00:00
      because it cost nothing              01/01/70 00:00
         yeah right              01/01/70 00:00
            yes, they do              01/01/70 00:00

                  I think your solution is better              01/01/70 00:00
                     I guessed so...              01/01/70 00:00

                     I can see a 'lucky sample' of a shift re              01/01/70 00:00
