Indeed. They have python built-in too now, which is an improvement. And a color screen. And a processor that’s probably 8x faster. But in its essence, it’s only been free / forced upgrades as the old stuff fell off the market.

Interesting. I didn’t know they had progressed that much to add Python.
I had a 81 or 82 back in the day then my kids needed one and my old TI had screen issues so we ended up having to buy one new four or five years ago.
The markup on the hardware is ridiculous. I haven’t tried their newer algebraic / symbolic calculators yet…but I kinda want to buy one just to try it out.
