With
the TI-1766 Texas Instruments entered 1981 the market of LCD-calculators powered by solar
cells. During the life cycle the internal construction and the design got
slightly revisions. This late model was manufactured in 1984 and uses a printed
circuit board similar to the TI-1895.
The
printed circuit board (PCB) inside this TI-1766 manufactured April, 1984 carries
the designation "Toshiba TI-1766III". How to distinguish between the
1st design,
2nd design,
3rd design and this 4rd design?
