For those like me who don't have an Reverse Polish Notation (RPN) calculator but would like to try one out or use one without actually getting a unit, here's one by Hewlett Packard.
I've always been a Casio devotee. And currently my scientific calculator of choice is the FX115MS. Love it. Has every function I need. If it were programmable it would be perfection itself.
where can i purchase this programmable calculator?
