The TI-25 SOLAR is a really unique scientific calculator with only the minimum amount of functions. It could be called the successor of the TI-30 Challenger.
We know the design of the TI-25 SOLAR from the US-built
campaign started three years earlier with the TI-7000,
Even the colorful Fun Calc makes use of the same assembly technology.
The TI-25 SOLAR was soon replaced with the TI-25 STAT still assembled in USA and the TI-25X Solar manufactured in China. Both added some statistical functions to the TI-25 Solar.
The TI-25 SOLAR carries the "Made in USA" logo. If you read the small printed on the back of the calculator you'll notice the sentence "With foreign and domestic components". If you opened the calculator before reading, you would pronounce the word "foreign"!
An identical printed circuit board (PCB) was used with the TI-30S sold in Europe and assembled in China.
Don't miss the TI-8230 printing desktop calculator manufactured in the U.S.A., too.
