Welcome to the Old Calculator Web Museum. Let me introduce myself. I'm Rick Bensene, the curator of this museum. I am a computing/ network/telecommunications professional, with over 40 years of experience in the industry. 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 in the 1980's, and development of this website beginning in 1997.

The museum pages aren't fancy, focusing on content rather than flare. This museum is devoted to preserving, documenting, and sharing the technology of desktop automatic calculating machines -- from the automatic electro-mechanical calculators of the 1950's and '60's, through the development and later proliferation of desktop electronic calculators from the mid-1960's through the mid-1970s.

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

I'm always looking for old calculators of interest. If you have an old machine which was made between 1950 and 1975, I may be interested in making it a part of the museum. For more information about specific machines I'm interested in acquiring for the museum, see my 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 drop me an EMail with information about the machine.

These pages are dedicated to the loving memory of my Mom, 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.
