Thanks Yann, I have for sure. I am trying to codify and make 19683 two input gates usable not just the few that seem usable, like ones as they are close equivalent to the binary versions.  To me, it should be an easier path to learn ternary by making circuits that are simpler and less complex  than binary. The difficulty arises at the most fundamental levels, "yes" or "no", where the "maybe" should not be called the third term, rather it is the meniscus of the other two terms. Regards Arto.  

I'm sure you have found other ternary computers on HaD :-) The search bar is full of results.
