HP 35s and Solve button (but not in equation catalogue)

Karl Schneider wrote an excellent article on SOLVE and INTEG on HP's RPN-based models.

Original implementation

HP-34C
HP-15C
HP-41C/CV/CX with Advantage Pac

Later implementation
HP-32S
HP-42S
HP-32SII
HP-33s
HP-35s

In it, he describes a method to create a MISO solver for the 34C, 41C and 15C, effectively replicating (or emulating...) the solver functionality in later Pioneer models.
