It awed me as well. Plus, the performance and such gave me inspiration that homebrew might be an answer to non-subverted computers post-Snowden. At least, for the bootstrapping phase of other computers, SCM&#x2F;builds, or key storage.<p>Only thing was that a HW guy told me the TTL chips he used might be hard to come by. I looked them up and had trouble finding them. So, rather than cloned, the next Magic 1 should be ported use components currently available... preferably 10 year horizon. Also, ideally something fabbed at 0.35 microns or above for visual inspection. Plus realism, as we&#x27;re practically cheating if you&#x27;re using deep submicron for &quot;hand-built, old-school&quot; systems.<p>What kind of primitive components are you using or found consistently available?
