A very basic calculator with solar cells and a memory. In 1999 most calculators sold in Europa carried an Euro-conversion like the -2001.

TI-1726_PCB.jpg (98370 Byte)This early TI-1726 from the first production year uses still a conventional IC-housing, while later TI-1726 calculators used the chip-on-board (COB) technique.

The Sharp LI3154 calculator chip was used in the cheap TI-503SV, too. A somewhat sleeker calculator was available with the TI-1706SV.

This TI-1726 is one of the 6 calculators that were awarded with the Blue Angle environmental label. But Texas Instruments never decorated the calculator with the logo.
