This Datamath II alias TI-2500 II was manufactured in Spain. Main differences are the changed label on the backside of the calculator and the different designation without the dash. Don't miss the US-built TI-2500-II (yes, with a dash between TI-2500 and II).
The Datamath II seems to be the last TI calculator using the standard Klixon™ keyboard technology.
Recently fellow collector Dave Wilson reported an European TI-2500-II (with the dash) manufactured in Italy late in 1975.
