Today someone (who is not on Mastodon) released a collection of more than 570 distinct operating systems, pre-installed with VM configurations for the 250+ different platforms, going back all the way to 1948.
Now, I have to admit I'm posting this without trying it myself, as I'm running low on disk space on this machine.
Because the full download is 121GB (174GB unzipped!). There is also a lighter version at 14GB that will download stuff on demand.
