Unless I’m misunderstanding something, the linked Wired article is about a person designing and making very primitive new chips from scratch, not recycling and modding existing CPUs.

While it is very impressive and surely a great way to learn, its not cost effective at all for what results.

Are you asking if a hobbyist can open up an old cpu and add parts to it to make it faster?

Most distros include a tool to convert or install packages from other formats. I’d look into that. I’ve never used Arch so unfortunately I can’t be more specific.

I’ve never used that printer or Cachy OS. That being said, I don’t think installing HP printer software will help with an Epson printer.

Epson do have printer drivers for linux and you can look up your specific printer download here https://download-center.epson.com/search/
