Back in the 90s my High School only had Acorns for the students, although there was a lab of them with the PC cards wed play Scorched Earth on.
I had an Amiga at home and was so frustrated at not having access to x86 PCs.
In hindsight I realise how fortunate I was to learn programming and be exposed to these different very forward thinking OSes very early.
RISC OS began my experience of hacking software by being able to click into the application and edit stuff. Trying to bypass the security to do more on them also honed early development and explorative techniques too.
