Description

The listing, Circular Slide Rule has ended.

Before calculators and computers, these were used. Mostly by people tthat would be called GEEKS today.

In engineering school, a salesman would come in at the beginning of the term. His pitch included, "They will do half of your work." Usually, someone would say, "I'll take two of them."
