RPN-67 NP +4

RPN-67 NP is the non-programmable 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 NP allows you to load and run 25 original HP sample program cards. It 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 NP is a very capable vintage scientific calculator.

Features:

• "Live" display of stack, memory registers, program counter, flags
• Virtual paper tape printer
• E-mail or print the paper tape
• Cut/copy/paste display value
• 30 selectable background images, even add your own.

More 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 key

All advanced features may switched off with a single setting, allowing you to experience a real HP-67 as closely as possible.
