Dear Fellow TI Calculator Programmers, Hackers, and Enemies,
As of this date, May 31, 2002, I am officially retiring from my position as president of Kevtiva's Calculator TI Calculator programming group. Ever since that first calculator I have always enjoyed my TI-83. That first TI-83 I had at GlenBard North High School, as a freshman, I remember going into the Math Office after school asking for help with the TI-83 I was borrowing from the school. I had no clue as to how to use the TI-83. The manual was so thick, and I just wanted to know how to do simple algebra on it! The man in the office kindly showed me how to use it, and that's where it started. After that, when I went into the link menu and I didn't know how to get out of the "Waiting..." screen, I took out the batteries and reset the memory! After leaving GlenBard North during my Freshman year, Mrs. Anthony was my Wheaton North Geometry teacher. She taught us how to program our calculators. I remember that first program I wrote, the quadratic formula program, or maybe the midpoint formula. Anyway, I had the program display "Thank you for using the quadratic formula program. Please deposit money" and you had to input a number. Of course, that program you could give negative numbers.
I continued toying with the TI-82 and TI-81 calculators, sometimes even staying after school (Geometry: 7th period) playing with the calculators. I remember asking "Is there an ' and ' function on this calculator. "No", she replied, "It's only on the more advanced calculators, like the TI-82." Looking back on that day, I have learned from tutorials like Brandon Green's, that for the TI-81, instead of using ' and ', you can use '(X>7)(X<34)', instead of ' or ', use '(X>7)+(X<34)'.
Soon after that, my friend Kevin Mallory, president and founder of Kevtiva, purchased a TI-83 for himself. He loved it, and was going crazy making all these "half-finished" games. I told him how I had been playing around at school with them, and I starting play'n with his, seeing what he made, and seeing what I could make on his. I really wanted to borrow it, and put my program on it, and refine my program. Shortly thereafter, I bought a TI-83 with money I received as an Easter gift.
I began the 'difficult' task of learning TI-BASIC. I would look over the manual, and learn whatever I could understand. But the biggest help, was that one BASIC program which wasn't protected. All the basic programs I could find, except BLACKJAK, were protected. Well, that blackjack game by someone was what really helped me understand how TI-BASIC really worked.
