If you're a visual learner, check out Ben Eater's channel: https://www.youtube.com/user/eaterbc

He has a really great video series where he builds a small computer from scratch on breadboards. Also some other highlights:

Reliable data transmission, more educational: https://www.youtube.com/watch?v=eq5YpKHXJDM DIY VGA "video card": https://www.youtube.com/watch?v=uqY3FMuMuRo

Super educational, but if you want to get into more embedded hardware hacking, I would say that building a homemade computer like he does is probably not a super exciting place to start. I'd recommend picking up some Teensy 4.0 microcontrollers and build some small hardware projects with the microcontroller before diving into lower-level circuitry.
