HP 35s

Finally noticed page 15-10,15-11 in the user guide...never liked having to use the algebraic entry method in the equation mode to enter a function to integrate. Thankfully, integrating using RPN works just fine using program mode!

The latter method actually is how HP Solve and integrating exclusively worked on the 3* series and other calculators until the 32SII got its algebraic equation mode, which found its way into the 33S and 35s.

Edit: Of course, the was the "RPL solver", interestingly starting with the non-RPN/non-RPL HP-18C in 1985.
