On Sunday, I found my old ThinkPad X31 in the basement and successfully booted Arch Linux 2.6.31 from early 2010. Web browsing was not so much fun, mainly due to the fact that many websites are served via HTTPS only, and Firefox 3.5.6 doesn't support the cryptographic ciphers from 2020. – https://imgur.com/IPWS2Ox<p>Then I've successfully installed Debian 10 buster: https://imgur.com/a/QvTA87C (showing i3 occupying 113 MiB of RAM)
