There is a simple logic calculator posted on sourceforge,

There are definitions for three different systems. The Kleene system (K3) was
developed to accommodate undecidable mathematical statements. The third
assignment in this system intuitively represents partial ignorance. The
Lukasiewicz (L3) system was developed because of the need to represent future
contingent statements. The third value is designed to represent indeterminacy.
The third value in the Bochvar (B3) system is designed to represent
meaninglessness. The third value in B3 is infectious.

This code was modified some time ago to run in GNU Prolog 1.0.0 . . .
