This Datamath was replaced after 6 month with the Version 3.

Like most other versions of the Datamath calculator this one was manufactured in Spain, too. Don't miss the sibling TI-2500.

Recently we discovered a TI-2500 Version 2 manufactured in United Kingdom.

A similar calculator to this TI-2500 Version 2 was sold under the label of Longines Symphonette. View it here.
