RPN-25 CE — Photo-realistic HP-25C simulator for the iPhone


Version 1.5

RPN-25 CE is a simulation of Hewlett-Packard's popular second-generation scientific calculator HP-25C.

Released on August 1, 1975, the HP-25 scientific calculator was the second member of the so-called "Woodstock" series (between the HP-21 and the HP-22.) It was followed a year later by the improved version HP-25C which sported "continuous" (non-volatile) memory. Both versions were discontinued in 1978.

RPN-25 CE is an enhanced version of the HP-25C.
