In this video I complete the testing of the PCB to identify and resolve the remaining problems with the board. This is in preparation for fixing the PCB layout and ordering a new set of PCBs. Spoiler Alert: I find more problems and I troubleshoot them on camera.
I also introduce a CircuitVerse project while will be built out in parallel with the 16-Bit Computer From Scratch. CircuitVerse is a digital simulation web site in which I am going to duplicate a much of my work as I can. It also provides a playground where you can play with the computer virtually as I build it out.
