Felix - 計算機 - 1960-1970
The Felix calculating machine, which since 1925 was produced in Kursk, at the Counting Mash plant, added the name “Felix” in 1931. In the 1940s, the adding machine was the most popular computing machine in the world. It was called an "ingeniously simple, convenient, portable and cheap" adding machine. It was the Felix model that by the end of the 60s made up the vast majority of calculating machines produced (300 thousand per year). And only pocket electronic calculators, which appeared in the 70s, were able to surpass the famous “Felix” in all respects and push it out of use. Size 30*16*12 Weight 5 kg. Made in USSR
