The
Datamath TI-2510 could be easily distinguished from the other members of the
Datamath family. This one is colored in a lighter beige compared to the others.
With the replacement of the TI-2500 Version 3 with
the TI-2500B Texas Instruments changed the internal
construction of the original TI-2510, too.
Another great
difference to the original
TI-2500B design is the absence of rechargeable batteries.
Dismantling both the TI-2500B and TI-2510 reveals
only one difference - a switch in the battery compartment to disconnect the
charging current.
A more detailed comparison between the ten known Datamath
Versions could be found here.
In Spain a
TI-2511 was
manufactured with the original color of the housing.
The last evolution step of the Datamath calculator was the odd
TI-2500-II introduced more than two years after the
original type.
