I don't think I was ever happier as a programmer than I was in the early 90s, well before university, with no thought of the internet, writing games on my Amiga.
Incidentally, I recently replayed Loom, from a bit before that era. It's still a lovely, wonderful game! Such a shame the fan-made sequel (Forge) seems to have died.
Loom is the best looking EGA game ever made. Sadly the VGA remake was hit-and-miss with the visuals.
Impossible to think about Loom without thinking about the first room in Money Island and the guy with the badge
I had two faster (Pentium 3) machines but firing up my dad's old Pentium 90 running redhat that I installed to use KDE to write C was just a beautiful feeling and really got me coding for a few years.
Even games were at least partially open (quake) or easily moddable (command and conquer, tribes, etc.) so I went down that rabbit hole soon after.
Also man I really miss BeOS.
