Hello Old Friend

[pier4r]

Gerson! I saw the first time the bigger version in your picture in high school, when the team of our school trained for the national Olympiad of physics! The professor took out this fatty semi laptop that turned out to be a big calculator (that evening used only for simple arithmetic).

I was ecstatic but I did not pay too much attention to it because we started to crack problems (that evening we did only 3, with 5 people. One of which went on to win the gold medal, in the Olympiad of mathematics, in my country. Nevertheless he was not selected for the IMO team. So far the only true gifted person that I met in person)

Anyway it was exactly the same model that you have on the left.... no wait, it was a TI calculator, I remember the logo. Did the TI have a similar model?
