Alright, I modified it as such. It still does it. That was,actually, my first thought, because I know the switching circuit is very sensitive. It seems that the two 74HC192's are having errors holding the input value of 60. When I press the reload switch, it loads the 60, but then it jumps to either 99 or 88, and it's always one or the other.
I have another circuit similiar to this, but it's input value is 32. Also, I modified the wiring on the first gate of the 74HC20. In my other circuit, pins 12 and 10 are each pulled high through a gate from 74HC14. Logically, I would think it could work either way. Am I wrong in the assumption? Could the way I have it wired now be causing a problem?
