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.

Not what the OP asked for but related.

The link below is for a near perfect simulation of the classic HP-15C RPN calculator. Works on both desktop and mobile.

In a former lifetime, I was an engineer. I bought one of these in the early 1980s and used it for almost 40 years before the screen died. Very popular among my colleagues at the time.
