The ZENTREX PROJECT
The Zentrex Porject was my first calculator system and introduced the whole concept of fantasy calulators. These virtual machnes imitate as well as can be don the pocket calculators. I chose the slide rule, aka scientific, calculator becuase I am part of the Scientific Utopian culture of the 1950's and early '60's. The pocket calculator has it's roots in sci-fi.
