Wow, same, went to uni from 1990 to 1996, everything was HP-UX, so I installed Linux on my 386 then 486 at the time, easier to do the homework, transferred on floppy. Always had a Linux partition, of course DOS/Windows was used for gaming, Linux for tinkering and dev. I don’t game for years so I’m Linux 100% for years now. I have a windows XP in QEMU for AVRStudio, damn thing cannot make it works in wine because of serial ports.
