Give it a 2 Gb swap partition and it would be a nice machine for TUI stuff, maybe occasional Fedi scrolling with Bloat and surf. I have a ThinkPad T40 with half a gig of RAM and 1,5 GHz Pentium-M: I can run gomuks for Matrix chats, mutt for email, amfora and w3m, and tut for TUI Fedi experience — it's not THAT bad.

You can still watch YouTube in 720p using mpv and yt-dlp on a machine like that, you can even try 1080p encoded with low complexity, but forget about doing it over the network: https and ssh give this CPU enough extra workload to make the video stutter, I'm not kidding you — so internal storage only.
