Numbers Game Circuit Update

This week, I finished my circuit on the breadboard. I had a couple of issues when I was trying to complete the process. My first issue was the diagram of the circuit, which can be accessed in the link below. The diagram says that pin 3 on the 74LS247 microchip should connect to the display, when it should say that pin 13 connects to the display. Also, one of the pins on the 74LS192 microchip was not properly functioning due to an improper amount of voltage coming out of on of its pins, so it needed to be replaced. Lastly, it turned out that a common anode display was needed for this circuit instead of a common cathode display. Once these problems were fixed, however, the project worked smoothly.  I am now in the process of laying out my circuit on a PC Board.
