TI-EC_BOX.jpg (52122 Byte)This TI-EC5 was introduced in 2006 together with the TI-EC3 and TI-EC7 Pro in Europe. It followed the -2002+ tracing back to the -2002 introduced already in 1999. It is not easy to follow the decision path why a complete series of Euro-calculators was introduced in 2006. Please remember that on January 1st, 2002 the introduction of the new bank notes and coins took part in EMU (European Monetary Union).
