Just wanted to show off the lowest end hardware I ever ran Linux on

https://lemmy.world/post/31425060

I’ve run Linux on a 166MHz Pentium with 64MB of RAM. There’s not much modern software that will run on that hardware though.

You would be surprised. If you stay text only and use a 32 bit distro, it would run up to date versions of most CLI programs.

Adelie and Arch32 still support Pentium.

Booting to a GUI, there are still a few options. I think Velox would run on that. I bet Xorg with FVWM would too. You are not going to have much left for apps though. However, you could run a couple of terminals.

Adelie Linux (totally modern Linux distro) lists 64 MB as the minimum server memory requirement.
