Setun (Russian: Сетунь) was a balanced ternary computer developed in 1958 at Moscow University. It was one of the first practical ternary computers, using three-valued ternary logic instead of two-valued binary logic prevalent in computers before and after Setun's conception. The computer was manufactured by the Kazan Mathematical plant. 50 computers were built.
