HP 11C compact RPN scientific calculator.  This is one of five compact "Voyager" models initially made in the early 1980s. The 11C was not made after 1989, so they are somewhat rare and cost nearly as much now as they did when they were new.   This is a very capable little calculator. Not only is it packed with features, I like the horizontal layout and small size for an RPN scientific.
