It reminds me a little of people who restore old cars, yes, there's something great about it, but no, I'm not interested in driving a Model-T around myself...
You are right, but my A2Z is not like old cars or vintage computer. It's more like designing and building from only few existing parts a karting, or a small buggie, without refering to existing drawings. A very simple machine, not very advanced, but that I understand in all its details.
Yes, the "finished" status of A2Z is what I am the most proud of. Lots of "CPU on FPGA" projects only deal with the CPU itself, and will never become a fully "usable" computer. I managed to work on the 3 main topics : hardware, software dev toolchain, and software itself.
