One-person project ships 1,700+ pre-installed OS images spanning 1948 to present inside a single Linux VM with QEMU, VirtualBox, and UTM support.
Key Takeaways
570+ distinct OSes across 250+ platforms: mainframes, minicomputers, workstations, home computers, mobile, and research systems all included.
Full and lite download editions available; full runs offline, lite fetches guest disk images on first run, both support incremental updates.
Custom emulator-independent launcher handles snapshots for reverting broken installs; hypervisor shortcuts provided for Windows, macOS, and Linux hosts.
Many entries required patching emulators for modern Linux compatibility; some installs took nearly a week and include era-appropriate add-on software.
Coverage includes CTSS, Multics, NeXTSTEP, Plan 9, Xerox Star/ViewPoint, classic Mac OS through 10.5 PPC, and Windows from 1.0 to early Longhorn betas.
Hacker News Comment Review
Discussion is light; commenters mostly expressed nostalgia and asked about specific obscure entries rather than raising technical concerns.
A question about TempleOS inclusion was answered by pointing to the project’s own readme, suggesting the catalog is well-documented.
