I have no idea what I'm looking at here.

Are you saying that your PC design has four parts in it, one of which is a PC part?

I would guess that it doesn't work because it seems like a complete mishmash

Look at the description of what PC needs to do. Take each case one at a time.

Keep in mind that, in general, what PC needs to output is related to what it output last time. That means that PC has to be able to remember what it output last time. What does that tell you about one of the parts you are going to need (i.e., if you are going to remember something)?
