Texas Instruments calculators

Texas Instruments is 'the other' large calculator manufacturer of the United States, next to Hewlett-Packard. And I think they are underrated by many collectors. In the haydays of pocket computing devices, the '70s and '80s of the previous century, HP sure did make some outstanding tools. But after that, in my optinion, TI took the lead and hasn't let go since. Models like the TI-89 and TI-92 are simply outstanding pieces of engineering.

And don't forget the TI-59, from 1977. With its almost 1000 programming steps and 100 numbers of memory it was a true beast back then. Adding the PC100 printer/docking station, you had a serious computer on your desk.

The list of Texas Instruments calculators is sorted chronological from oldest to newest.

This isn't a comment, just a quick question. I've got a TI flight caculator (avstar) and the screen took a dump.....not a good thing in flight! Anyway, I replaced the batteries, but no luck. I'm thinking it may be a screen/window problem? Do you know anyone or any place I might send it to to get it repaired? At this point I'm willing to try anything. Can you point me in the right direction? Thanks Tom M.

Hello Ahmed,

Thank you for commenting on http://calculators.torensma.net
Unfortunately I do not have the specification of all 700 calculators in my head, so I am unable to tell you which TI compares to then Casio fx-880. Please feel free to compare calculators on my site any time!

Thanks again and good luck.

Kind regards
