 		 #129047 - At the IC
Responding to: ???'s previous message
Connect the caps from The +5 (VCC) pin on the IC the the ground connection on the Chip. Short leads, as close to the chip as possible. ! cap fot the 8051, RAM, and '573 chips. Check the data sheet for the RAM chip. Some like a tantalum cap also.

                     i have seen your profile            01/01/70 00:00      
                        It seems to have changed            01/01/70 00:00      
                     At the IC            01/01/70 00:00      
                        have a look            01/01/70 00:00      
                           Erik by god it is recently changed!            01/01/70 00:00      
   I think Neil is asking            01/01/70 00:00      
   Isn't this a 'C' problem rather than a RAM problem            01/01/70 00:00      
      Really?            01/01/70 00:00      
         code tested at simulator            01/01/70 00:00      
            So it's a hardware fault            01/01/70 00:00      
               Hardware tested            01/01/70 00:00      
                  answer to "why":            01/01/70 00:00      
                     but dont forget to put pull ups its port 0!            01/01/70 00:00      
                        for the test - yes, sure, sorry, I forgot            01/01/70 00:00      
                  "Hardware tested" and who gives a hoot            01/01/70 00:00      
                  Tested?!            01/01/70 00:00      
            it's the HW then            01/01/70 00:00      
         Yes, it looks like that.            01/01/70 00:00      
            Oh no it doesn't!            01/01/70 00:00      
               first of all, let me be clear ...            01/01/70 00:00      
                  not just stuck-at            01/01/70 00:00      
                     Good point!            01/01/70 00:00
