The second design of the TI-1766 II sports for unknown reasons larger solar cells than the first edition introduced just one year earlier. Texas Instruments entered already in 1981 with the TI-1766 the market of LCD-calculators powered by solar cells. It took only two years and the cheap looking TI-1706 appeared and found its own way. 

The next generation of both the TI-1766 II and TI-1706 II gave still a difference in the appearance. Don't miss the TI-1768 of the same era sporting a tiltable display.

Dismantling this TI-1766 II manufactured in 1987 by Inventec Corporation reveals a standard design centered around an unidentified single-chip calculator circuit.

In 1988 the design was slightly changed, don't miss the last TI-1766 II.

The third generation - named TI-1766 III and TI-1706 III - wiped out the flair of the TI-1766 and used similar housings.

Today we know the TI-1766+ introduced in 1996 and the value is back again.
