TI-1706SV_G1099_PCB.jpg (216656 Byte)TI-1706SV_G1099_Back.jpg (101652 Byte)The TI-1706SV was introduced in 1998 and uses a smooth design as a teaser for the later -2001 calculator. The featured calculator was manufactured in October 1999 by Kinpo Electronics, Inc. in China.

The internal construction is typical for a late four-banger and uses a single-chip calculator circuit manufactured by Sharp Electronics of Japan, a small solar-cell array, and a coin-shaped battery.

About 2 years after the introduction of the TI-1706SV its internal construction was changed and the calculator chip bonded directly to the printed circuit board (PCB). This Chip-on-Board (COB) technology avoids the housing of the integrated circuit and hides its part number. 

If we trace back the history about 15 years we discover products like the TI-1706, TI-1706 II and TI-1706 III with similar specifications.

In 2003 Texas Instruments introduced with the TI-503SV, TI-1706SV and TI-1795SV a new design style. The calculators are now optimized in the wind tunnel for best aerodynamics...
