RTR12,
Yes. The missing image is the same as the professor's diagram. One thing that helped me was to put each component on the breadboard individually to make sure that I knew how it worked. I then started combining components and testing the results. The optocouplers and Schmitt triggers both have pretty simple wiring schemes, so they were pretty easy. The shift registers were more complicated, and I was glad I spent some time experimenting with them.
