• Here is a list from the Texas Instrument website
http://www.ti.com/ of what all of their products are. Quite a bit more than just a calculator. I think most electronic company’s are well known for one major product, but in order to stay in business must also produce other things as well. I remember I have always used a Texas Instrumetn calculator for all of my educational needs and for home use. I wouldn't buy anything else.
