DATAMATH CALCULATOR MUSEUM

Datamath Commemorative Calculator

DALLAS (April 1972) The famous TI-2500 Datamath calculator was first announced in April 1972 with a suggested retail price (SRP) of $149.95. Beginning June 1972 first customers got in the Neiman-Marcus and Sanger-Harris department stores in Dallas, TX their calculators before the formally introduction on September 21, 1972.
For the later production an off white material was selected to not show dirt and finger marks.

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 rechargable batteries and features even an Online-Manual.
