A gift from my Calculus teacher upon graduation.
Yes manual included. Sadly the 0 (zero) button no longer works, due to battery corrosion… ☹️

You might have gotten an 83, as it fixed some sort of issue with the 82
Probably the 0 button going bad XD
Already said that in my original post, but thank you Mr Quicksand!
I might manage to fully fix it one day, I think it’s a corroded via.
IIRC, the 83 model fixed some issue with the accuracy of fractions or something like that.
