Commemorative Calculators

DALLAS and WEILHEIM (September 21, 2002) „To celebrate the 30th anniversary of the wonderful TI-2500 Datamath™ calculator the Datamath Calculator Museum gives you one as a present!

Compared to the old-fashioned original calculator this Windows™ compatible Datamath Commemorative replaces the 4-bit single-chip calculator circuit with Pentium™ power, lacks the acid NiCd rechargeable batteries and features even an Online-Manual.“

The Datamath Commemorative Calculator was realized in a cooperation between the Datamath Calculator Museum and Kirk B. Muri. In the past months we received a lot of positive feedback from enthusiastic users all over the world. Motivated by this success we decided to continue the approach of Windows™ compatible calculators emulating the most important Texas Instruments products. 


In a first step we improved the original Datamath software emulator to replace the standard Windows™ calculator and added the skins of both the green Longines Symphonette Electronic calculator and the rare white Pre-series Datamath manufactured already in June, 1972.

The next steps will introduce the so-called Smithsonian Collection of Texas Instruments calculators.

Within the History of Integrated Circuit Technology of the National Museum of American History a special section traces the infancy and growth of integrated circuit technology at Texas Instruments. The collection covers the most important calculators using TI’s MOS/LSI technology including the SR-10, SR-50, SR-52, TI-59, TI-1500, TI-2500 and TI-2550.
