Why plan for less than the raspberry pi level?
But the doomsday scenarios aside, this is super useful as an educational device. It can teach people what computers actually are and how they operate on the lowest possible level.
I've also got 2 desktops from 2003ish (Athlon64 and Pentium III), they probably work, too, although they're stored in a garage (along with some other stuff like VCRs and CRT displays).
Not to mention routers old and new, all running Linux.
Yeah, why plan for less? All I need to do is scavenge around my property :D
Though a garden, livestock and a greenhouse will be a much higher priority. No one needs any sort of computing when they can't eat.
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.
And I'm also thinking more of a "repository of knowledge" use, not just simple controllers.
TI calculators, microcontrollers, and more:
> 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.
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.
