Ask HN: Should there be new RPN calculators to replace the TI-84?

I took an exam today where only TI calculators were available. I felt I was caught between some older models where the TI interface was not quite worked out.

And I don't see much progress then trying my daughter's TI-84.

TI calculators are not RPN. I think HP made (makes?) RPN calculators.

Yeah, I'm also confused by this... the only RPN calculator I know of is the HP 15C, which is old school and not used in education.

Business courses frequently use it
