Not Ranked
My first was a T. I. Calculator. My dad broke it. He would literally pound the keys when entering numbers until he broke the contacts, under the keypad. It cost me something like $80.00 and it had a PI function.
I still have my sliderule, You were forced to use the sliderule, even if you had a calculator. It was a whole class in college.
Darn, I get to go to the Cardio Doctor and get my monthly checkup.
