I'm trying to build a digital clock for a final project for my high school
digital electronics class, and I was wondering if anyone could help me out.
My idea us to use 3 74HC390s, and then 4 seven segment displays. However I'm
not sure exactly how I would get it working in base 12 and base 60 for time,
and I'm not sure how I would get it to reset when it reached 12:59. I also
am not sure of how I would be able to get a solid once second pulse to run
the timers. Any help would be greatly appriciated.
