Calculator History Timeline

Copyright ©1997-2024, Rick Bensene and The Old Calculator Museum

Last Updated 5/22/2024

This page of the Old Calculator Museum is a timeline of known historical points, people, milestones, and other time-related material relating to calculating machine technology. Also included are some benchmark historical points relating to the early development of "individual computing"; with small computers of the late 1950's into the late 1960's, as well as timeshared computer systems debuting in the 1960s providing some of the earliest opportunities for individual students, scientists, and business people to have access to sophisticated computing resources for the first time. At nearly the same time, beginning in the early 1960's, the arrival of single-user electronic calculating machines also provided access to personal calculating capabilities originally in the engineering lab or large accounting firm, but not much later into the home and small office. Copyright ©1997-2024, Rick Bensene and The Old Calculator Museum

Some historical references are included for the early development of the single-user oriented computers, including early single-user mini-computers, and eventually, the microcomputer.

Most especially, the microprocessor and microcomputer were made possible directly and as a result of the technology created for the electronic calculator. The drive for calculator manufacturers to push the semiconductor manufacturers them to pack more and more circuitry in ever smaller amounts of space, using less electricity, providing more functionality, and perhaps most-importantly, reducing cost, was the force behind the development of digital integrated circuits for their first use in a consumer-based product. The evolution of this technology eventually, through the desire of a number of calculator companies to produce a calculator that was powered by a simple programmable computer on a chip, led to the development of the microprocessor. Once this happened, making calculators on a chip was not a big deal anymore. The big deal became making ever-more powerful computers on a chip. It was then that microcomputers made it possible for personal computers in the home began to appear on the scene, which clearly changed our world forever.

Note that most of these "personal" computing developments were made long before the famed IBM PC (incorrectly called the first "Personal Computer" despite its name) or Apple Macintosh came to market. These computers were the beginnings of the true utility of a personal computer, which, over time, have evolved into the personal computing platforms of choice for people and business all over the world today.

These infant personal computing benchmarks are included here simply because the threads of all of these events interrelate in terms of the development of calculating devices intended for use by an individual in home, school, laboratory, research & development/engineering, or office.

This document was created from a huge number of sources that are too vast and gathered over such a long period of time to begin to account for. Some of the information here was gleaned from various online resources such as Wikipedia and BitSavers. A large amount of information was also gathered from vintage periodicals and newspapers, as well as product flyers, product manuals, marketing materials, and documentation from calculator manufacturers(such as annual reports and internal/external publications) that the museum has accumulated over the years.

Some information is also gathered through interviews with the people involved with the projects to develop various calculating and computing devices at the time. The museum curator has had the incredible luck and privilege of meeting (in person, over the phone, or through Email) with some of these players in the industry during the formative period of the electronic calculator, and was able to gather a tremendous amount of information through these interviews. As such, some content in this document is not guaranteed to be 100% accurate in all aspects, as some of the information is based on the memories of people "who were there", whose memories have inevitably faded over the years. Best effort has been made to obtain alternate sources of information to corroborate such memories before they are published in this document.

There are cases where the definition of terms can be interpreted in different ways, such as when a product is "introduced" versus when it is actually available for sale. In the electronics and computing industry, a product introduction does not necessarily mean that the product can be purchased and delivered at the time of introduction. Effort is made in this document to provide introduction dates, as well as dates when a product was actually available for purchase. Some companies at the time (and is still a common practice today) made a point of introducing product as much as 18 months before the product was actually available for purchase.

All efforts are made to try to assure this document is as accurate as practical, and updates are promptly made when sources of information converge to provide a more accurate dating of a given event. Of course, if anyone reading this material identifies factual errors or any other kind of error such as spelling, punctuation, duplication, ordering, or formatting, please let the museum know by clicking the Email button at the top of this page. Reported errors will promptly be investigated and corrected as necessary.

Some information that is presented may inadvertently be in violation of copyright law, as it is very difficult with old periodicals and newspapers to determine the copyright status of material. If a representative of any organization or an individual believes content on the Old Calculator Museum website is in violation of copyright law, please click the EMail button at the top of the page and send a message including the full URL of the item(s), and a claim relating to how the content is in violation of copyright law.
