: Strictly speaking, all of them.  Any calculator which requires you
: to calculate, say, a square root or a trig function by first entering
: the number to which the operation will be applied, then pressing the
: operator key, is an RPN calculator.  The fact that most of them use
: infix entry of simple arithmetic doesn't change this.

With the Sharp 1500 you enter the equation exactly as you write it.
ie "2 * sin 45" you press "2", "*", "SIN", "4", "5", "=".  I always
liked this calculator because if you see the equation on the display, 
and you can go back and edit the equation if you get an answer that
looks "funny".  This feature is also present in the Sharp 5100, or the
Radio Shack PC-2 (pc for Pocket Computer) line.
