I have been looking for a basic RPN calculator that the display shown 4 lines of the stacks X, Y, Z and T
Functions including percent and square root with 4 Store Register Arithmetic.
Nobody make this kind of basic RPN calculator on the market.

Assuming you don't have one, have you considered the HP 35s?
I know it is the opposite of a "Basic" RPN calculator but you don't *have* to use anything more than what you want. It is a RPN machine, shows two stack levels (X and Y), is still in production, is not too large and is relatively inexpensive. Maybe something to consider.
