Haha, same vibe! Mine was running mandrake/mandriva + kde. Also programming on such a low specced device gave a superpower (and good coding hygiene): you would immediately spot memleaks and inefficient code because you would feel it as entire seconds of slowness and unresponsiveness. Like, none of my GUI apps had work happening on the event thread, but I could immediately tell which ones would.

Unrelated to your post (I missed those form factors) but has imgur become enshittified too? If I try to zoom in on your picture it gives me a popup I can’t clear telling me to install the app. Sad.
