RPN calculators are still being sold by HP. This includes financial, scientific, and graphing calculators. The current RPN HP graphing calculators leave a lot left to be desired, and aren’t as good as the old ones. I have an HP 50g RPN graphing calculator which is amazing. But, there are even better ones that are no longer in production. Swiss Micros makes remakes of such amazing HP calculators: https://www.swissmicros.com/products https://www.swissmicros.com/products At some point I will purchase the DM41X from there.
