Passage: One early calculating machine, built by Thomas Fowler entirely from wood in 1840, operated in balanced ternary. The first modern, electronic ternary computer Setun was built in 1958 in the Soviet Union at the Moscow State University by Nikolay Brusentsov, and it had notable advantages over the binary computers which eventually replaced it, such as lower electricity consumption and lower production cost. In 1970 Brusentsov built an enhanced version of the computer, which he called Setun-70.  In the USA, the ternary computing emulator Ternac working on a binary machine was developed in 1973.The ternary computer QTC-1 was developed in Canada.

Question: What was the latest computer developed by Brusentsov in the 1970?
Setun-70
