Same except mine was over 30 years ago (an OG TI-85). Still on my desk, still use it almost every day for something or other.

I don't know how the TI-85 compares to the other models without looking it up, but there's a forever soft spot in my heart for mine. It got me through a comp sci degree and still works flawlessly today.
