RPN-67 Pro

A dream calculator of the 70’s, priced at $1,900 in today’s dollars, now on your iPad!

RPN-67 Pro is the first complete simulation of Hewlett-Packard’s legendary HP-67 programmable calculator for iOS. Produced from 1976 to 1982, the HP-67’s features coupled with its capability to store programs on magnetic cards made it a huge success among scientists, engineers and other professionals. Thousands of programs were written for it. Now you can run them right on your iPad, with more ease and faster than ever before. To get you started quickly, download hundreds of program cards from our website for free.
