User Feedback:

1. "The functionality is comprehensive. Impressive!"
2. "This software emulates the rare HP financial calculator from 1974 immaculately. It faithfully reproduces the original while enhancing it. It operates faster, with increased accuracy, features 10 additional storage registers, and a convenient popup window to view stack contents, financial, and storage registers. Additionally, it incorporates TVM4 functionality for compound interest and accumulated simple interest. Truly a remarkable creation!"

Features:

• Authentic appearance modeled on an actual device
• Responsive keys with audible clicks (adjustable volume)
• Complete implementation of all HP-70 functions and operations
• Correct erroneous entries by swiping across the display
• Copy/cut/paste display values
• View stack and memory registers by double-tapping the display
• Visual indicators to monitor input parameters
• 10 non-volatile memory registers (not present in original HP-70)

The HP-70, a highly scarce calculator, was discontinued after a single year and is now exceedingly hard to come by in any condition.

NOTE: RPN-70 SD meticulously simulates the vintage HP-70 calculator and has been verified against an actual device using examples from the Applications Cookbook section of the HP-70 manual. In some instances, what seems like a software issue might actually be reflective of an idiosyncrasy of the HP-70.

IMPORTANT: The HP-70 necessitates precisely three input parameters from the top-row keys, of which at least one must be either "n" or "i." In other words, PMT, PV, and FV cannot all be input parameters simultaneously.

An iPhone version called "RPN-70 HD" is also accessible.
