The
second version of the different Datamath calculators could be easily recognized
at the closed bottom. This calculator uses 4 built-in NiCd batteries that
couldn't be replaced by the owner instead the 6 batteries of the Version
1.
A more detailed comparison between the ten known Datamath
Versions could be found here.
Don't miss the never released Minimath calculator

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.
