App Description

A dream calculator of the 70's, priced at $3,200 in today's dollars, now affordable for everyone!

RPN-97 Pro is the first complete simulation of Hewlett-Packard's legendary HP-97 programmable calculator for iOS. Produced from 1976 to 1984, the HP-97's features coupled with its capability to store programs on magnetic cards made it a huge success among scientists, engineers and other professionals. Thousands of programs were written for it. Now you can run them right on your iPad, with more ease and faster than ever before. To get you started quickly, download hundreds of program cards from our website for free.

What users said:
“The most delightful app I possess. The magnet card reader emulation rocks. Would have paid much more for this."
"As the owner of an actual working HP 97 calculator, I am blown away with this new simulator. Simply fabulous."
"Whoever coded this my hat goes off to you - what a professional piece of work, incredible app."

RPN-97 Pro is fully compatible with RPN-67 Pro, its companion simulator of the HP-67 calculator.

• "Live" display of stack, memory registers, program counter, flags
• Show program usage notes
• 30 selectable background images, even add your own
• Much faster than a real HP-97

• Complex numbers mode, hyperbolic functions
• Non-volatile memory - stack, registers, program, flags, paper tape
• Status indicators for prefix keys (EXT, f, LBL, GTO, etc.)
• Display showing thousands separators (optional)
• Text output on 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 name while entering or single-stepping a program
• Change the duration of the PAUSE command
• Cancel SST or BST operation by simply sliding your finger off the depressed key
• Compress constants in programs into a single step (reversible)
• Use existing programs in text format by a simple paste operation

RPN-97 Pro 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.
