A dream calculator of the 70's, priced at $1,900 in today's dollars, now on your iPhone!
RPN-67 SD is the iPhone version of RPN-67 Pro, the first complete simulation of Hewlett-Packard's legendary HP-67 programmable calculator for the iPad. Produced from 1976 to 1982, the HP-67 was a huge success among scientists, engineers and other professionals. Thousands of programs were written for it. Now you can run them right on your iPhone, with more ease and faster than ever before. To get you started quickly, run the built-in program cards, or choose from the large number of programs available as free downloads from our website.
What users said:
“This version permits you to use your virtual HP-67 just as you could the original - hand held and highly portable. Congratulations to the developer for providing such an excellent and aesthetically pleasing software product."
"This was my first scientific calculator in real life. It is great to have the simulator on my iPhone. The special features added make it into a HP-41 or 42S! It comes packaged with some great samples. Am having great fun with it."
