I was analyzing my old TriBOS code, and I realized, that I cannot change 2-bit system to 3-bit. Also, changing 10-bit to 3-bit is hard too. TriBOS converted 2-bit to 3-bit with a classical method, and 10-bit to 9 bit with classical methon and then to 3-bit. Now I simplfied connection of 3-bit and 2-bit, and I think is was a great idea. Now TriBOS converts 3-bit to 4-bit with classical methon, and then 4-bit to 2-bit! It is 16% faster! I think, if I rewrite TriBOS with C/C++, I could programm special micro-processors with trinary logics!
