I could probably build a computer from scratch, but it's not gonna be a modern one with impossibly small microchips and bajillions of transistors. It's gonna be a room-sized behemoth with only like 8bits of memory that takes 24 hours to compute 1+1.

Check out Ben Eater on YouTube.

He uses a microcontroller though for his breadboard PC. A microcontroller that is built in a fab.

I was going to add that disclaimer, but it's also a step closer and interesting nonetheless.

I'd also recommend Breaking Taps, while he does amazing stuff in a home lab it also has the disclaimer that he's able to get it already has some super interesting but rare stuff. Electron microscope etc.

I thought I saw someone making homemade, low power processors but for the life of me I can't remember who or where.

Sam Zeloof did it.

That's the 6502 one you're talking about though, what about the previous one (granted it still used a bunch of ICs, but not a microcontroller per se)
