A dream calculator of the 70's, priced at $4,200 in today's dollars (2024), right 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."
Features:
• Virtual program and data cards
• Virtual paper tape printer supports all HP-97 printer modes

• Text output on simulated paper tape in 10 colors, even simple plotting
• Stack-of-stack: push/pop the entire stack on internal stack (4 levels)
• Single-step into subroutines (optional)

• Keycodes translated to command names while entering or single-stepping a program
• Change the duration of the PAUSE command
• Compress constants in programs into a single step (reversible)
RPN-67 SD comes with more than 130 programs pre-installed, including HP Standard Pac, HP Business Decisions Pac, HP Math Pac I, HP Stat Pac I, and HP Surveying Pac I.
The simulator has been verified to correctly run the examples given in HP Civil Engineering Pac I, HP Clinical Lab Pac, HP E.E. Pac I, HP Games Pac I, HP M.E. Pac I, HP Navigation Pac I, as well as large number of programs published in Users' Library Solutions.

• In "Max" mode, results such as 9.99×10⁹⁹ now appear correctly rounded both in the display and on the printer for all decimal point settings, e.g. SCI DSP 1 (in contrast to the original HP-67).
• Certain calculations, e.g. 100⁷⁵, caused the app to crash.
