In this video, I perform some sanity checking on the 74LS04 Inverter IC I had incorrectly hooked up last time. Before I go on, I need to know if this IC can still be trusted.

In this video, I complete version 1 of the Clock Module by adding the inverted clock and buffering the clock outputs for the LEDs. I also relocate the Power Supervisor from its prototype board to the Clock Breadboard.
During one of the cleanup fast-forwards, I (finally!) give a little background about myself. I had an introduction video recorded and quickly got rid of it. Instead, I plan to provide some insight to my background during as voice-overs to some of the sped up tedium. If you have anything you want to know about my background, please ask.
I mention Ben Eater's 8-bit Breadboard Computer as part of what let me to this point. You can find his series here: https://www.youtube.com/playlist?list=PLowKtXNTBypGqImE405J2565dvjafglHU
I also mention James Sharman's 8-bit Pipelined CPU. You can find his series here: https://www.youtube.com/playlist?list=PLFhc0MFC8MiCDOh3cGFji3qQfXziB9yOw
You can view my first view the how I build the power supervisor and its test circuit here: https://rumble.com/v1klug3-0002-testing-the-power-supervisor.html
While there are still a couple of odd jobs remaining for this Module, I will not circle back with any significant changes until later in the build.

In this video I update the Register PCB schematics and completely rebuild the PBC to be a 4-layer board. This improves the manufacturing capabilities and is a complete game-changer for this PCB layout. I cannot overstate how much more I will get for the incremental costs to change to a 4-Layer board!

In this video I begin the process of building out a register. This video focuses on the Input, Storage, and Output (to LED) of data. In this video, I also construct a bus testing harness for testing input data for the bus by hand.
This register does not yet conform to the design rules I have set out for myself, so expect additional work to follow on the Register Module.
I also create a custom ribbon cable. James Sharman also demonstrated how to make these cables. Check out his video and consider following him as well: https://www.youtube.com/watch?v=7Lb1Dawq4cQ

In this video I discuss my interpretation of decoupling capacitors and how I will use them during my build-out. I am trying to get ahead of ground noise issues and I believe that decoupling capacitor placement is what is required.
Part of my approach is a departure from what I consider common practice. Am I right? Am I way off base? Who knows! This is why it's, "The World According to Adam."
Now, I would not knowingly present any false information. That said, there is also a chance I am wrong here.
I also make an attempt at a full ground layer for a breadboard which ends up in a FAIL.

In this video I take a Mulligan (a do-over if you are not familiar with the term) on the Control Logic video I published prior to this one (Video 35): https://youtu.be/VJB3dIfV6VQ.
No sooner had I published the video had I realized I made a number of mistakes which make the work from the previous video unusable. I correct those problems here.
This video is what video 0035 should have been.
