Description

Full name is Texas Instruments TI-95 PROCALC. Allthough the landscape dimensions suggest otherwise, this is actually a keystroke programmable calculator. And it's another of those Texas Instruments engineering tools. It comes with an industry strength plasic cover and quick-reference card. And the keyboard feels really solid and is nice to use.

I have #0002533. My dad thought it was a good gift when I was 6. I probably spent 1000 hours on it trying to figure it out. It was strangely fun to try to make do something new, that I had never seen it do before even when I did not understand many of the math functions.
