I'm struggling to see how it's a manifesto instead of a design spec. I was hoping to learn the perceived advantages of this architecture. (With a lot of brain power I could probably figure that out, but I haven't had my coffee yet.)
Regardless, it's an impressive amount of work to spec out a ternary computer, although I think the Russians did it a long time ago.
EDIT: I did a lot of work with an expert system that had ternary logic (1=true, -1=false, 0=uncertain) over floating point values so I like the concept. I'm just not sure it extends to general computing.
There are 10 kinds of people in the world, those that understand binary, those that don't, and those that didn't expect this joke to be in ternary.
