Stories from the “good” old days running Linux on a 386 machine with 4 MB or less of memory aside, in the present day it’s still perfectly normal to run Linux on a much weaker machine as a server - you can just rent a the cheapest VPS you can find (which nowadays will have 128 MB, maybe 256MB, and definitelly only give you a single core) and install it there.
Of course, it won’t be something with X-Windows or Wayland, much less stuff like LibreOffice.
I think the server distribution of Ubunto might fit such a VPS, though there are server-specific Linux distros that will for sure fit and if everything fails TinyCore Linux will fit in a potato.
I current have a server like that using AlmaLinux on a VPS with less than 1GB in memory, which is used only as a Git repository and that machine is overkill for it (it’s the lowest end VPS with enough storage space for a Git repository big enough for the projects I’m working on, so judging by the server management interface and linux meminfo, that machine’s CPU power and memory are in practice far more than needed).
If you’re willing to live with a command line interface, you can run Linux on $50 worth of hardware.
Yeah, but at least we knew how to switch consoles.
I bet that most Linux users nowadays don’t event know the CTRL+ALT+Fx shortcuts to switch console.
Can’t say that the old days were really “good” compared to what we had now, but there was definitelly a lot of satisfaction in step by step getting the system to work.
