Deli Counter
In this project we were instructed to design a counter for a Deli that would count from 0 to 80 that had two inputs. The first advancing the counter by one and the second resetting the counter.

Conclusion
1. SSI is AOI gates and MSI is flip flops
2. Can only count in binary, and are difficult to make function
3. Also called Propagation delay. Is when the numbers experience a delay and appear to flash in asynchronous counters.
4. When I press space in my circuit the clock begins counting. Once the right hand hex display reaches 10 it shows a value of 0 and the left hand hex display increases by one. This process is repeated until the hex displays show 80. Then they pause. Once I press space once again the hex displays show 00 then with another press the counting resumes.
5. Yes. Max decided to have a separate flip flop on the same clock as the 74ls93 that counted up by one every ten rising edges
