I started on a Ti-83 and better yet could take other programs online and load them and then modify to my desire.
When the teacher said show your work I wrote out the program I made to calculate the equation. They banned calculators altogether.
Once there was a computer I traded sleep to stay on it. I worked professionally for almost 3 decades and it ultimately cost me my health and mental health. It was often my own insecurities and anxiety that led me up the ladder.
I left the field and went to work for something I believe in and my tech skills are like wizardry to these folks.
There is a lot of blue sky to explore for people in tech.
TI-83 was also my gateway drug into programming. Good memories!
What field did you go into?
