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?
