You are familiar with this calculator? It is almost identical to the 4rd version of the TI-1766

This LC-847 II replaces the LC-847, the perfect twin of the original TI-1766.

LC-847II_IC.jpg (42676 Byte)The LC-847 was the first calculator using solar cells sold by Toshiba. Please notice that with the beginning of the solar cells era a total of 10 elements was used. Later products use just 4 or 5 elements due to the reduced supply voltage of 1.5V instead the previous 3V for the calculator chips. An identical printed circuit board (PCB) was used with the Radio Shack EC-402.

Toshiba? Compare this calculator with the TI-1766 and TI-1895.
