I want my TI-25

I have no idea what made me investigate this, but I seem to be experiencing bouts of nostalgia. Or maybe it's a 'I bet you can find this online' vibe.

My first calculator was a Commodore 776M. A gift, as always, from my grandfather. My second was the TI-25. They were compulsory and could be bought through school.

I thought my TI-25 was the coolest thing ever, even if I had very little use for it. I think the battery lasted 15 years before it started leaking. I kept it for many years after that, eventhough it was dead, just because I liked the feel of it in my hand.
