Tiny Core Linux: a 23 MB Linux distro with graphical desktop

I've used many of these small Linux distros. I used to have Tiny Core in a VM for different things.

I also like SliTaz: http://slitaz.org/en, and Slax too: https://www.slax.org/

Oh and puppy Linux, which I could never get into but was good for live CDs: https://puppylinux-woof-ce.github.io/

And there's also Alpine too.

I tried a handful of small distros in order to give new life to an old laptop with an AMD C-50 and 2GB of RAM.

The most responsive one, unexpectedly, was Raspberry Pi OS.
