Vilen Plotnikov, 1960
Vilen Nikolayevich Plotnikov (1930-2000) - Chief designer of "Carat" computers family, who had an exellent feature of prediction of the progress in the field of scientific computer technology. A man of good nature, benevolent to people, artist-amateur, expert in literature.

Vilen Nikolaevich Plotnikov was born on January 31, 1930. In 2020, the Chief Designer of the Karat computer is 90 years old. The memory of him remained in the hearts of everyone who knew this wonderful Man.

"......The "Carat" family of installed computers, developed under Vilen Plotnikov management, was the first in the Soviet Union broadly used in navy radio-electronic systems. The important indicator of computer perfection is mean-time-between-failures which consisted more than 2 000 hours (almost 100 days) for the first "Carats" and more than 10 000 hours (almost 5 years) for the next modifications. At the beginning of 70-s these figures seemed to be fantastic. But computers used in surface ships and submarines and operating under conditions of high humidity, great temperature fluctuations, weight overloading required this very reliability.
"Carats" passed the exams: many computers had operated on board for 10-15 years without a single failure! Within these years more than 2 000 computers were manufactured at the plants of Ukraine and Russia! They were used in systems of sixty modifications..."
