My name is Adam. I'm building a 16-bit computer from scratch. I hope you will join me on this journey.

In this video, I begin the control circuitry for the register module, following the design I set forth in video 13 (https://www.youtube.com/watch?v=IGfEUpnUFiE).

I have revisited the length of my videos and have broken this wire-up into shorter segments to try to keep the content at a manageable size. I will continue to do this going forward, making shorter videos on a more aggressive release schedule as I can.

With that said, Part I completes the wire-up of the LEDs and Line Drivers and extends the control signals to their respective ICs.
