So, this isn't exactly retrocomputing and it looks like it's from four years ago, but I just found it and thought that many here may find it interesting.

This guy built a simple 8-bit CPU out of essentially discrete logic circuits (from what I've see so far, nothing more complex than a 4-bit adder chip) and explained the entire process.

@me @retrocomputing

  1. extremely cool
  2. The thing is, while rolling back experienced computer performance/degrowthing computing clearly has to happen
    I think hand-wired 8 bit computing is an educational rather than practical thing. (Obviously 8 bit AVR MCUs are a practical thing). 32 bit physical lisp machines on fpgas! (Eventually)

Oh yeah, I can't see any practical use outside of educational, but for that purpose, it's a fantastic resource.
