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 rechargable 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. 

The next steps will introduce the socalled 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 technolgy 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.
