I am passionate about preserving and sharing information about old electronic and electro-mechanical calculators. I have run across some interesting machines over the years, and figured I'd put information about them up here for others to learn about and enjoy. If you have questions about any of the machines listed here, or have more information or comments regarding this site, please don't hesitate to drop me an EMail.

A listing of content of the museum by manufacturer is available and can be seen by clicking HERE.

The machines are arranged in the list in rough order as to their age (based on date of manufacture, not introduction), oldest to newest. Click on any of the links in the list below to learn more about each of the calculators in the museum.

Calculators listed that do not have a link associated with them do exist in the museum's collection, but have not yet had exhibits prepared for them.


Many pages include a "Spec Sheet" for each machine. The Spec Sheet includes a summary-style rundown of the general information on the machine, such as size, weight, power requirements, technology used, features, quirks, and more. Calculators with Spec Sheets will have a Magenta-colored arrow in the list below. To see the Spec Sheet for a machine, simply click on the main picture of the machine (or the "Specs" link on the navigation bar at the top of the page) shown at the top of each page. The Spec Sheet also has links back to the main page for each machine, to related or similar machines, and back to the main list of calculators in the museum.
