I apologize for the delay in getting this video released. I have had a lot of travel this month for work, and have not had a ton of available time to produce the video footage I have. Thank you for your patience.

In this video I test the timing of the control logic circuits I carefully planned. Once I have some real timing data, I need to go back and re-evaluate my expectations. Overall, I am able to reconcile my expectations and the obervations I make, and align them properly.
