DATAMATH  CALCULATOR  MUSEUM

Datamath Commemorative Calculator

DALLAS (August 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. At that time Longines Symphonette was primarily selling music - boxed set treasuries - Frank Sinatra, Mozart, etc.
However, they viewed themselves as a direct marketing company, as well, and also produced a catalog that featured a number of hard goods products including the Electronic Calculator, actually a TI-2500 Datamath calculator in an olive housing.

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.
