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. | |||||||||||||||||

UX could use a delay before the next move. | |||||||||||||||||

Brilliant to get this done all the way through. Once you introduce a HDL and start optimizing, I would expect more than half of the transistors to be redundant. But you would end up with a circuit that you will not understand any more.. But that could give an important lesson in chip design and HDL compilers. | |||||||||||||||||

Sweet. About the same number of transistors used in the Intel 4004. | |||||||||||||||||

That's a lot of transistors. Why do I feel it could be done in less? This is the absolute minimum number of Discrete transistors you need? | |||||||||||||||||

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 | |||||||||||||||||
