I keep thinking that for home tinkering this is really the wrong approach. Surely there are other more DIY-friendly ways to make switches besides with semiconductors? Sure, they wouldn't achieve anywhere near the same density as SOTA semiconductors, but that's not really possible at home anyway.

I guess you could always go back to electromechanical relays. I wonder if it might be possible to come up with a method of 3D printing those?

But in practical terms the Z80 was a 4 um process node so unless you're willing to go back to the proverbial stone age it seems like you need semiconductors and lithography.
