60 Minute counter. Uses an 2 x AND and a NOR gate on 4 bit line to reset each digit on 10 or 6. (bin 1010 or 0110 - 1’s are ANDed and 0’s are NORed - outputs are ANDed to signal reset on current digit and clocked (up) input on next digit. On an endless loop. Want to add a pause button and a reset button next, if I can find space on the limited workspace.
