Welcome to the Electronic Calculator History and Technology Museum. The purpose of this site is to preserve the history of electronic calculators by using the Internet to display information relating to the machines developed during the 1960s and mid-1970s.
From the sale of the first all-electronic desktop calculator in the early 1960s through the transition of calculators to commodity status in the late 1970s, electronic calculators served as an important target for design engineering efforts that resulted in the acceleration of technology during a critical time in the electronics industry. Calculators were the first item that could be sold in large quantities that required development of Large-Scale Integrated Circuits for their success. The R&D efforts put into LSI chip development helped develop new processes & technology that found applications in many aspects of everyday life. The first microprocessor was developed originally as a calculator chip, which served as a springboard for an entire industry.
Unfortunately, because calculators became so commonplace 20 years ago, much of the information and many of the early machines themselves have been thrown away. It is my hope that by using the Internet to create an Electronic-Museum, information about the development of and technology behind early calculators can be preserved for the future.
Desktop Calculators - Electronic desktop calculators from 1963-1975, plus some interesting later models. Also included in this section is a reference directory of nearly 1000 desktop calculator models.
HP Calculators - Calculators manufactured by the Hewlett-Packard company, both pocket and desktop category machines.
Pocket Calculators - Electronic pocket calculators from the early-mid 1970s of all types (basic, scientific, financial, etc.)
