Fantastic machines, aren’t they? It is always fascinating to me what technical progress mankind is capable of.

Oh for sure :slight_smile: I had lost a feature on calculators between ~ 1990 and 2000’s ::: the fractions. It was on my first Radio Shack calculator. And then it reappeared on different Japanese models. :jp:
I bought my Ti-89 calculator with all the books I could find on it since 2000. I just love it.
I just change the batteries in it when they are done.

I truly love mathematical calculating machines. I think my wife thinks I love them to much :wink: lol

This is the recent model:

Thanks for your post :smiley:
