I still use an Atom N270 netbook, and DuskOS is on the edge; but there are zillions of Atom netbooks in LaTam and in the outside as goverments agreed to ship these to students. With TUI/CLI tools you can do wonders, far more than CollapseOS. Yes, I know Forth, I did a good chunk of Starting Forth.

UXN once tweaked it can run stuff like Oquonie.

BTW, a properly set Emacs can double as a great legacy platform too; from IRC to whatever (Bitlbee<>IRC), Web browsing, email, gopher and gemini browser with elpher (and the Gemini proxy gemini://gemi.dev), epub reading, music and video (Emacs' emms, but mpv+yt-dlp can be set to play stuff at 480p/720@30FPS), Usenet client, RSS, Elisp itself, M-x calc and Gnuplot, PDF viewer (pdf-tools), Org-Mode+Hyperbole to expand your brain like nothing, sokoban gaming, Tetris, ZMachine text adventures with Malyon, MUDs, trace routers from OpenStreetMap with osm.el ...

For stucking I/O:

Usenet->slrnpull+GNUS.

Mail->Mu4e+mu.

People doesn't know that today computers from 2003 can do wonders and access far more services than they would think.

Once you can do TLS 1.3 'fast' enough (P4 w/ SSE2), you can do anything from IRC, email, gopher, gemini, usenet and rss from proxies and terminal or Emacs clients.
