Welcome to the Old Calculator Web Museum. Let me introduce myself. I'm Rick Bensene, the curator of this museum. I'm 55, 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 in the mid-1960's.

The museum pages aren't fancy, focusing on content rather than flare. This museum is simply devoted to preserving, documenting, and sharing the technology of desktop automatic calculating machines -- from the electro-mechanical calculators of the 1950's and '60's, through the beginnings of the pocket wonders we have today, which had their roots in the early 1970's, and on into the beginnings of the desktop computer of the mid-1970's through the early 1980's.

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 George and Emma Sayers, my Godparents. They are two people who had a very special place in my life, and hold a very special place in my heart.
