EC-1033: History of Creation and the Structure

The paper describes the management principles and development process of a Series One medium-performance computer, the ES-1033, and the circumstances that led to its creation. The ES-1033 was developed by the Special design bureau of the Kazan Computer Factory (SDB KCF, Russian: CKB K3эBM). It remained in serial production from 1976 to 1983 and was the most numerous of Soviet medium-performance computers, with 2300 units produced. With 220 000 operations per second for double length floating point problems, 150 000 operations per second for economic problems with decimal arithmetic, and 1 million operations per second for RR-type registry operations, the computer was compatible with all Series One computers and fully complied with the IBM/360 operating principles; however, it was a radically new product in terms of circuitry. Technical solutions implemented in the ES-1033 project are protected by 17 national invention certificates and over 90 patents of other countries, including the USA, UK, France, Japan, and West Germany.
