@dpwiz collapseos is so silly. The real post-collapse hardware will be all the old discarded android phones that you can power with a bicycle, which in the UK we have 50M of, according to a reasonable approximation. I tried to validate the hypothesis of collapseos and not only failed to find Z80 hardware in stores, but couldn't find any self-hostable hardware Z80 system online.

Maybe I'm stupid, but collapseos is a meme, nothing more. Has absolutely nothing to do with collapse resistance.

Heck, probably a bluetooth mesh network implementation will be more instrumental for post-collapse society than it.
