Time to remember it. How better than to run it through its paces on your iPhone?

By using the real thing, of course. ;-)
The 34C was my very first HP calculator.

Yes, Solve and Integrate were powerful new functions on the 34C. They have been thoroughly discussed, and the manual uses many pages for explaining their use, interpreting the results and more.

Which leads to the question how all this is done by RPN34. Especially the 34C integration routine is quite sophisticated, and I wonder if this is also true for the emulator. As far as I know the algorithm has never been published, so the details are unknown. So: what are the methods that are implemented in RPN34? I assume they are not identical to the original algorithms, so the results can differ.
