Solver, HP Solve, etc.

Addendum: The classic RPN solver functionality is implemented in the HP-34C, HP-15C, HP-42S, and HP-35S. Not so sure about the latter. There are also solvers in some algebraic models (e.g. HP-27S, HP-17B) but those are different. I'd guess there are solvers in the RPL machines but can't tell you about their features.
