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
remaining versions.
Another great difference to the original
TI-2500 Version 3 design is the absence of rechargeable batteries.
Dismantling both the TI-2500 Version 3 and TI-2510 reveals immediately one
important difference - a switch in the battery compartment to disconnect the
charging current.
Exploring
the TI-2510 is quite interesting, the printed circuit board (PCB) sports two
mystery holes, an unknown Power Supply circuit SN27720 and an unique PCB
designation 30614E.
With the introduction of the TI-2500B the original
TI-2510 was updated internally and received an identical printed circuit board
(PCB). Don't miss the later TI-2510.
