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:
