TRON is just a specification, but there is a tron-conforming open source os-skeleton available. Skeleton means it lacks code for communicating with processor and memory, if I remember correctly. It does have the higher-level interfaces and some drivers ready as well as the real-time time-allocation stuff.
Also, you already have an I(ndustrial)-TRON system if you have a Japanese camera or car.
This is the current project's web site: www.t-engine.org
So, TRON isn't 'non-existent' as some people seem to believe.
