Sir Eric yes this is our school assignment.... hmm actually yes! I could consider making it a 120 second timer. However, I wish to make it a chess timer actually.
two 120 seconds are displayed.
120 120
there is a button for each side. When the button is pressed lets say the right button, the left timer will countdown. Vice versa for the other one. Do you think that is simple?
hi Mark,
I showed the change from RCO to Min/Max on that rough drawing I posted.

Do you mean the same IC counter drives two LED displays, as selected by a push button.?
It would be easier and cheaper to build two complete counters in the same box, trying to switch the LED pins would be a task!
