'''Setun'''  ({{langx|ru|Сетунь}}) was a computer developed in 1958 at [[Moscow State University]]. It was built under the leadership of [[Sergei Sobolev]] and [[Nikolay Brusentsov]]. It was the first modern [[ternary computer]], using the [[balanced ternary]] numeral system and three-valued [[ternary logic]] instead of the two-valued [[binary numeral system|binary]] logic prevalent in other computers.<ref name="cabinet">{{Cite web|url=https://cabinetmagazine.org/issues/65/weatherby.php|title=Hegel 2.0 &#124; Leif Weatherby|first=Leif|last=Weatherby|website=cabinetmagazine.org}}</ref><ref name="dataart">{{Cite web|url=https://museum.dataart.com/ru/history/glava-2-kiberraznoobrazie/|title=Глава 2.
