RPN-67 Free is the free version of RPN-67 Pro, the first complete simulation of Hewlett-Packard's HP-67 legendary programmable calculator for iOS. Produced from 1976 to 1982, the HP-67's capability to store programs on magnetic cards, wide array of functions, merged keycodes, indirect addressing and other enhancements made it a huge success among scientists, engineers and other professionals. Thousands of programs were written for it. RPN-67 Free allows you to run, but not modify, five sample program cards. The free version lacks the program creation and card management features of the Pro version, as well as its massively expanded array of functions and operations. Apart from these restrictions, RPN-67 Free is a very capable vintage scientific calculator.Features: "Live" display of stack, memory registers, program counter, flags Virtual paper tape printer E-mail paper tape, or print it via AirPrint Cut/copy/paste display value 30 selectable background images, even add your ownMore features the HP-67 never offered: Non-volatile memory - stack, registers, program Status indicators for prefix keys (f, g, h, STO, RCL, GTO, DSP) Keycode-to-command translation while single-stepping a program Cancel SST or BST operation by sliding your finger off the depressed keyAll advanced features may switched off with a single setting, allowing you to experience a real HP-67 as closely as possible.Pre-installed program cards of RPN-67 Free include "Calendar Functions", "Annuities and Compound Amounts", "Vector Operations", "Triangle Solutions", and "Circle Computations", all part of the HP Standard Pac that came with the original HP-67.The Pro version has been verified to correctly run the examples given in HP Business Decisions Pac, HP Civil Engineering Pac I, HP Clinical Lab Pac, HP E.E.
