€-1796 calculator was introduced 2000 in a dark, translucent housing.
Nevertheless displayed the Texas Instruments website in the 2000-2003 timeframe a white housing like the
TI-1796SV. This Prototype of the €-1796 gives
us a good understanding how the original design looked.
Dismantling this €-1796 manufactured probably around 1999 by Nam Tai Electronics in China reveals a clean design centered around an unknown single-chip calculator circuit mounted in Chip-on-Board (COB) technology on a small double-sided printed circuit board (PCB) and powered by small solar cells. A larger, single-sided PCB is used for the keyboard and connected with a short flat flexible cable (FFC). Nam Tai introduced this technology for Texas Instruments' Desktop Calculator Line in 1996 with the TI-1795+.
In 2006 Texas Instruments surprised customers in Europe with a complete new family of Euro Calculators labeled EC-3, EC-5 and EC-7 Pro.
