With no input pulse (state 1), output A is zero and output B is 1.5 v. With a positive input pulse (state 2),A and B are both 1.5 v. With a negative input pulse (state 3), A and B are both zero. A 12-v positive pulse at the reset terminal restores stale 1.-S. F. Summer, Two Unijunction Transistors Produce Three-State Circuit, Electronics, 39:1, p 100.
