You are familiar with this calculator? It is almost identical to the TI-1766, the first calculator using solar cells marketed by Texas Instruments.

lc-847_IC.jpg (90789 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.

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

The LC-847 was soon replaced with the LC-847 II.
