Welcome to the Old Calculator Web Museum. Let me introduce myself. I'm Rick Bensene, the curator of this museum. I live in a rural area outside of Oregon City, Oregon USA (near the end of the Oregon Trail), called Beavercreek, and am a computing/ network/telecommunications professional. I've been a fan of all kinds of technology since I was a youngster. Calculating machines have always been a fascination for me. That fascination turned into a passion, which led to collecting electronic calculators, and development of this website beginning in 1997.

The museum pages aren't fancy, focusing on content rather than frills. This museum is devoted to preserving, documenting, and sharing the technology of desktop electronic calculating machines -- from the very beginning of the electronic calculator in the early 1960's through the early beginnings of the pocket calculator of the early 1970's. Much of the technology that we enjoy today, such as personal computers, smart phones, tablets, gaming systems, and myriad other devices with microprocessor "brains", all have their genesis in the technologies developed as a result of the electronic calculator.

For more information about the museum, please see the FAQ (Frequently Asked Questions).

The Old Calculator Museum is always looking for old electronic calculators of interest. If you have an old calculator that was made between 1950 and 1975, the museum may be interested in making it a part of the collection. For more information about specific machines the museum is interested in acquiring, see the WANTED page or click the "WANTED" section below. If you have a machine which seems to fit these interests and are looking for a new home for it, please send an EMail with information about your calculator.


The Old Calculator Museum will host an exhibit featuring Wang Laboratories' line of electronic calculators at the Vintage Computer Federation's second annual Vintage Computer Festival-Pacific Northwest held at the Living Computer Museum + Labs in Seattle, Washington, on March 23 & 24, 2019. Click the links for more information about the Vintage Computer Federation, Vintage Computer Festival-Pacific NW, and and the Living Computer Museum + Labs.

Please come and see the Old Calculator Museum's exhibit, as well as a large selection of outstanding vintage computing exhibits, as well as guest speakers, a consignment area with vintage computing-related items for sale, and, of course, the fantastic Living Computer Museum + Labs, which is a treat in itself for anyone who has even a passing interest in the historical machines, people, and ideas that made personal computing possible.

These pages are dedicated to the loving memory of my Mom and Aunt, who loved my passion for these old machines. The site is also dedicated to George and Emma Sayers, my Godparents. These people had a very special place in my life, and hold a very special place in my heart.
