If master reset inputs 1MR 28/11/2004В В· I found a good schematic for a four decade counter using 4026 IC's with a switch debouncing circuit as well. It does not use the same IC's as in this discussion but you can add as many seven segment displays as you want. The 4026 IC only drives common cathode seven segment displays and the nice part here is that only one IC per display necessary.
