For My Context:

I found this stuff mostly through the Minecraft Computer Crowd, and then creators on YouTube like astro Sam, jdh, and inkbox, as well as people like the 8bitguy on retro computing in general, and obviously the plethora of retro gaming people.

My eventual goal is to design an entire 16bit computer, I've done smaller projects in Minecraft, but I want to try to do the real thing.

I've looked at both logisim evolution and digital ATM but I'm still kinda lost on what I should learn software wise😵‍💫
