Lol I read Linus’ release notes for Linux .01 (linked in the article) and I really liked this part listed under the hardware requirements

Finnish keyboard (oh, you can use a US keyboard, but not without some practise :-)
The Finnish keyboard is hard-wired, and as I don’t have a US one I cannot change it without major problems.

The requirement for a Finnish keyboard was literally hard coded into the first version of Linux. Hilarious.
