Counting 60 to 0

That schematic you linked at was flawed, so it's not the best basis for our conversation.

I suppose you want a decade mod 60 counter? That is, a counter that will display decimal numbers into two 7 segment displays. If so, let's start from the basics. Can you build a down counter that counts from 0 to 1 (0,9,8,7...)?

If you can do so, the system is as simple as duplicating the unit and using the appearance of a 9 in the units to clock the decades counter.

Is that clear?
