Vintageterminals.io – a bootable museum of vintage OSes (13 so far)

You can boot actual vintage images in-browser — terminal-only classics like UNIX v4 and GUI-capable builds like early Red Hat or Yggdrasil — and the site treats them like museum exhibits (filters, session counters, random-launch). The real trick is getting decades-old binaries to run in JS/WASM emulators and exposing them in a friendly catalog; it's not completely novel but the curation, UI touches (theme switch, launch modes) and breadth make it delightful and immediately playable. I'd like clearer provenance/links to source images and an obvious repo for the emulation plumbing, but as a demo + learning toy this hits hard.
