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.
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.
