A Work of art. I remember my dad building a computer using discrete TTL chips in our garage in Auckland. He took like two years and I'm guessing about five people saw it. I would love to see more of these on HN, but most don't get past a few upvotes in the sea of AI stuff.

Would standard HDL synthesis engines be better at this in terms of schematic capture? They could do optimizations that I think if I'm reading right weren't done here
