    I completed a timing diagram accordingly, as shown in the image:

    The instructions at the end say I need to use a 7434 chip. Here is the diagram:

    Although I was able to figure out the drawing, I need help making the wiring schematic showing all the needed chips and connections. I have been trying to figure this out for quite some time and would greatly appreciate it if you could draw the chips out on paper connecting, them with lines. Thank you so much for your time and help with this! It will help me learn a lot. :)

    This is confusing. Do you realize that a 7473 is a dual J-K flip flop? To complete the schematic that you already have, it would seem that all you need to do is to assign pin numbers to the inputs and outputs. Pick a quad dual input NAND gate type (74xx) for the one present, and assign pin numbers. The find a TTL inverter and assign pin numbers to the gate present.
