Description

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."

Features:

• Virtual program and data cards
• Virtual paper tape printer supports all HP-97 printer modes
• Powerful database-driven card manager
• Create, label, and organize a virtually unlimited number of cards
• Use iTunes to effortlessly save entire card collections on your Mac/PC
• Sharing: e-mail, AirDrop, Dropbox, copy, paste, print
• Editable listing shows labels, targets of branches, and errors
• E-mail listings and let the recipient paste the text right into RPN-67
• Print listings on any AirPrint-compatible printer
• Program listing on paper tape shows subroutine nesting
• Edit paper tape
• E-mail paper tape, or print it via AirPrint
• Cut/copy/paste displayed value or program steps
• Paste existing HP-67 listings into RPN-67 SD and run them
• "Live" display of stack, memory registers, flags
• Show and edit program instructions
• Fast: 1.5 secs vs. 6 mins (iPhone 6 vs. HP-67, determinant of 5x5 matrix)
• Low-battery indicator (iPhone charge 10% or less)
• Optional high-contrast mode for working in bright ambient light
• Compatible with RPN-67 Pro and RPN-97 Pro


While RPN-67 SD works like a real HP-67, changing a simple setting will turn the app into a super-charged HP-67:

• Up to 999 program steps, 8 subroutine levels, 6 additional flags (F4...F9)
• 100 additional registers
• 100 additional labels
• 100 built-in constants and conversions
• More than 150 additional powerful operations and functions

Plus:
• 15 commands to print and manipulate any range of extended registers
• Unrestricted register arithmetic
• Exchange x with any register
• Complex numbers, hyperbolic functions
• Non-volatile memory - stack, registers, program, flags, paper tape
• Status indicators for prefix keys (f, g, h, STO, RCL, etc.)
• Display showing thousands separators (optional)
• 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)
• Powerful debugging aids, including 10 breakpoints with counters
• 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.

What's New

Version 2.7

• Extended Data Card Support

Now you can load, create, update, delete data cards – all under program control.
A program can even check if a card exists and, if missing, optionally print its name.

See Extra Functions 30 through 33 on cuveesoft.ch ("Extensions") for details.


• Push and Pop Registers

Push the entire set of primary and secondary registers on an internal four-level stack, then pop the values back into registers later.

See Extra Functions 13 and -13 on cuveesoft.ch ("Extensions") for details.



Bug fix:

• TEXT Helper didn't handle quotes correctly if the device had "Smart Punctuation" turned on in Settings.

Really cool throwback.

My first HP calculator was an HP 29. A few years later, I got an HP 67. Later I bought a 15C and when I started an MBA program i got a 12c. It means a lot to have a really faithful representation of my old friend. I currently have this emulator plus a 12c and 15c (from different a vendor) on my iPhone. I love them all. Take it from somebody who know, all the emulators replicate their real world counterparts.

Fantastic calculator

Works perfectly and even emulates the battery indicator LED in sync with the iPhone battery level.
Would be nice to have the card reader Motor Sound emulated ;-)

I owned a 67

Good replica of 67. I have one issue that could be quickly solved. When I press the f or g key and then the display key, and enter a 4, the number of digits does not change from 2 to 4 and I would be happy.

Developer Response

Hi, what you describe is not how a real HP-67 works. f DSP simply sets FIX mode, g DSP sets SCI mode (and h DSP sets ENG mode). If you then type 4, you're starting a new number entry. To change the number of digits to 4 in any of the aforementioned modes, simply type DSP 4.
