Fantastic to have another option with modern tools! great work that will be appreciated by many. Between this, Puppy, and Tiny Core Linux so much old hardware can be put to potential use. I’d also mention Finnix as an excellent rescue image solution. Any other awesome projects for limited hardware and Linux use that should be more well known?
Not so much, actually. When you aim for anything that resembles modern “desktop computing” (maybe with at least some “web browsing”), you are limited to decent hardware configurations from last 15 years or so. Yes, you can show to your grand-grand-grandkids how it really was back in the days once, but you are not going to study the splash screens while programs initialize, or wait for each image to appear for a couple of seconds when skimming trough an archive, or watch page load progress bars move in the browser. But with that decent hardware, you almost always can install bog standard modern Debian with an ascetic desktop, and have much less support issues than with specialized system. It'll be the same Linux anyway.
Although it is possible that it won't work for some top performance purely 32 bit CPUs, because non 64 bit builds are certainly out of fashion today, even though some 32 bit distributions still exist.
