"Fred Jonkers started Termatrex systems in 1960. My father Wallace Hughes Green worked at Termatrex from 1968 - 1992. He was vice president of production and was directly responsible for the manufacture of the Termatrex reader system. In 1975 the owners of Termatrex changed the name of the company to Remac but retained the Termatrex brand as a retrieval data system. My father purchased the Termatrex name and production facility in 1975 and ceased operations in 1992. I worked there for years while in high school and college and am throughly familiar with the equipment, its manufacturing process and how the retrieval systems works. For nearly 30 years it was the most simple data retrieval systems of its kind in the world. How it works and stores data is an amazing piece of pre-computer technology."
Dr. Fredrick Jonker (no "s" at the end of the name) is the correct name of the inventor.
