We wrote the year 1989 when Texas Instruments started the US-built campagne. Together with the TI-7000 other models like the TI-7100, 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" !

The TI-7000 appeared in a white housing with the "20th ANNIVERSARY EDITION" logo.

If you feel familiar with the TI-7000 - compare it with the original design introduced in 1988 with a different nameplate: TI-307. 

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