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).

Dismantling the TI-EC5 reveals with a single-chip calculator circuit bonded directly to a printed circuit board (PCB) a technolgy known from the 1990's.
Shortly after the introduction of the TI-EC5 the successor TI-EC5+ was announced together with the TI-EC3+ and TI-EC7 Pro+. At first glance the only changes are a new up-to-date design but Texas Instruments told the customers of the TI-EC7 Pro the reason. Read this story here:
