Would the 28C's solver method of entry qualify? It predates the 48 series IIRC.

-B

Yes, the 28C and 28S have an algebraic solver, but I don't think they have a true "textbook" display, do they? For example, with integrals written how they would appear in a book, fractions with the numerator displayed above the denominator, etc. The 48 has the equation writer for entering expressions in this format, and I believe it will display them on the stack in the same way.

I do believe you are correct - I would call it functional but not "pretty".
