We wrote the year 1989 when Texas Instruments started the US-built campaign. Together with the TI-7100 other models like the TI-7000, TI-7200, TI-7300 and TI-7400 were introduced for Wal*Mart and other discounters. And all carried 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"!
If you feel familiar with the TI-7100 - compare it with the original design introduced in 1988 with a different nameplate: TI-306

In 1992 Texas Instruments changed the design of the series and we could a revised TI-7000, TI-7100 and TI-7200.

The last US-built calculator was the TI-7140.
