Part of the IFIP Advances in Information and Communication Technology book series (IFIPAICT, volume 357)


This paper presents a short history of the development ternary computers “Setun” and “Setun 70” at Moscow State University. It explains the characteristics of their architectures and programming systems (Interpretive Programs), the production and practical usage of Setun-computers, the structured programming on two-stack “Setun 70”, the dialogue system of structured programming – DSSP, and the computer assisted teaching system “Nastavnik”.
