> Or you know, a laptop. I've got like 6 of them piling up dust and all they need is 19V

Mechanical parts fail first. The keyboards on those laptops will be gone after a few years of use. The USB ports won't last much longer. How long will the thermal paste and internal fans last?

The point of the z80 is that they're cheap and relatively easy to build from scavenged parts.




Not sure where you scavenge parts for a z80, I think it's much easier to scavenge parts for PCs. Plus, laptops are way more fixable than you seem to think, with simple soldering. Fans can be kept going for years with grease. External keyboards are ubiquitous. It's strange how people here bang on about RPi when a simple laptop is even more flexible.

And I'm also thinking more of a "repository of knowledge" use, not just simple controllers.

TI calculators, microcontrollers, and more:

Collapse OS is talking about timelines of a century or more. Non-mechanical computers are the only ones that will last that long without the supporting infrastructure.
