The
Datamath TI-2511 was manufactured solely in Spain and uses an identical
construction to the TI-2510 featuring its unique beige housing.
Both
the TI-2510 and TI-2511 use 4 AA-size alkaline batteries, the use of rechargeable
batteries found in the sibling TI-2500B is not
possible.
How rare is the TI-2511?
This one is serial number 1855, the proud owner Javier Moreno Siguenza, living
in Spain, reported his TI-2511:
Date of manufacture: wk 42 year 1974
Serial number: 8818
We located recently a TI-2511 with the serial number AE 01671 and manufactured in December 1974.
A more detailed comparison between the seven known Datamath Versions could be found here.
The last evolution step of the Datamath calculator was the odd TI-2500-II introduced more than two years after the original type.
