I have a circuit, mainly a counter, with Led display driven by a 
16F84a that runs perfectly.
I changed the chip with a 16F628A , no change in the circuit I only 
replaced in the program the RAM beginning with 20h instead of 0Ch and 
of course processor and include file..
Now to start I have to momentary ground Rb0 and Rb4 never change.

There are any other replacement to do? There is some article that 
deal with this problem?
Thanks
Renzo Giurini
