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.

Even 7th and 8th grades use TI Nspire CX calculators in my area.

As rightbyte said, RPN is an HP thing, so if you want an RPN calculator, ask for an HP. Most test administrators can help you.

Not anymore, that's why older engineers pay inflated prices for old ones on ebay.

Sadly my HP 48G is dead dead (water damage and corrosion) and they don't have a replacement for that.
