Indeed, +1. I was the same though with a TI-83 instead. I had to get good at hiding the calculator under the desk in non-math classes because the English teacher (for example) would press me on "why do you need a calculator for English class?"

I'm kicking myself for not saving the game code I wrote for some of those early games. They weren't very good, but I'd love to see the code, despite the horrifying spaghetti that it was.
