The short answer is the HP 50g, which is an RPN calculator that can be programmed in RPL, which is fully RPN stack capable. The Prime cannot be programmed in either RPN keystroke like a HP 35s or in RPL. Also, the Prime is very buggy and unstable, and will crash frequently with loss of work since the last normal shutdown. I'm a retired engineer who used the 50g for many years, and would still use it today for professional work. The Prime is an educational toy.
