Lots of nostalgia here. I had an HP 48G and it had it's own legitimate programming language of which I barely scratched the surface. I programmed and downloaded all sorts of games on there. Wrote basic quadratic equation solvers and graphers. One of my favorite things about it was that it had an internal speaker. You could specify the frequency and duration of notes. I was in concert band at the time and was into "The Planets" suite by Holst. I ended up writing two programs that played the main tracks for Jupiter. I had another friend who had the calculator so I gave him one part and retained one for myself. We started both programs at the same time and listened to beautiful tinny classical music. It was stupid easy to output sound on that thing. Like someone else mentioned it was also very easy to output to the screen. I know applications are much more complicated than they were back then but I do feel bad for kids that they might not have a sandbox environment to try to push the boundaries for their knowledge. This kind of stuff got me hooked on coding.
