I started the Old Calculator Museum on the Internet in 1998 to bring to the light of the public Internet the fascinating and pivotal role in history that early electronic calculators had in the development of our world's technological transformation from the industrial age to the information age.

The museum pages aren't fancy, focusing on content rather than flashy web magic. The site is old enough that some of the photos are small and lower resolution, for back in the days when the most common form of Internet Access was dial-up. As time goes on, I'll be updating these photos to fit more with today's higher-bandwidth Internet services.

This museum is 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.

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 firest read the FAQ (Frequently Asked Questions), then drop me an EMail with information about the machine.
