TRON wasn’t just an OS but a whole integrated system, it was meant to be used with different parts working together. There was a whole TRON house tech demo built in Tokyo back in 1989 https://youtu.be/7jPKEyM44GU
If you want to try here is the BTRON 4.5 media, should work in modern VMs https://archive.org/details/chokanji
Hah, I realize I actually encountered this family in the form of a T-kernel offshoot that I evaluated for some automotive safety relevant application.
TRON didn't need a conspiracy theory to kill it, it was one of many overambitious computer projects that aimed too high and failed, the IBM Stretch being possibly the best-known example.
The OS is still around as uITRON. It's... very Japanese, which is why you'll find it inside a ton of Japanese IT gear and very little else. For most people the closest they'll get to it is in printers from Japanese companies. I've seen a derivative, NORTi, in a few products made in places like Brazil but that's about it.
