Monroe EPIC 2000 Announcement
The New York Times, December 2, 1964

Introduction of Monroe's first electronic calculator designed as a collaboration of Litton Industries, which had extensive experience in electronics due to its involvement in the aeronautical and defense industries, and its Monroe Calculating Machines division, which had become part of Litton Industries in October of 1958. Prior to the introduction of the EPIC-2000, Monroe was quite famous for its mechanical and electromechanical calculators, both in rotary and printing forms. Monroe, along with Friden and Marchant were the top three US manufacturers of calculating machines.

In the article, Monroe incorrectly claims that the EPIC 2000 is the world's first printing desktop programmable electronic calculator. This distinction actually belongs to Mathatronics, Inc., with their Mathatron Model 4-24 calculator. Mathatronics formally introduced the Mathatron 4-24 in November of 1963, over a year before the EPIC 2000 was introduced.
