It consists of a paper disc, with equal divisions running from 1 to 200 near the edge, and a clear plastic rotating disc. These are pivoted together at the center. The upper disc is marked in red with two perpendicular diameters. The lower disc is marked: MINIMUM LATENCY CALCULATOR FOR THE UNIVAC SOLID-STATE COMPUTER. The UNIVAC had a magnetic storage drum on which locations were specified numerically. The latency calculator allowed programmers to write code for the machine to make the most efficient possible use of the drum memory.
