TI-2510-Batt.jpg (26328 Byte)The Datamath TI-2510 could be easily distinguished from the other members of the Datamath family. This one is coloured in a lighter beige compared to the others. 

With the replacement of the TI-2500 Version 3 with the TI-2500B Texas Instrumnents changed the internal construction of the original TI-2510, too.

TI-2500B-Switch.jpg (55603 Byte)Another great difference to the original TI-2500B design is the absence of rechargable 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 detailled comparison between the ten known Datamath Versions could be found here.

TI-2511_CMP.jpg (24829 Byte)In Spain a TI-2511 was manufactured with the orginal colour 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.
