While you can recover the sample programs from within RPN-55, this procedure shows you how to
download the entire collection as well as individual programs from this website.
(iOS 13 and later: see tab Sharing)
On the computer:
Tap the button below to download the folder Sample Programs (see numbered steps.)
Or download the single program Hyperbolic Functions.
After extracting the programs from the ZIP file, you have several options to transfer them to RPN-55 on your iPhone:
- iTunes File sharing
- AirDrop
- E-mail
On the iPhone:
Tap one of the buttons below.
Since the files are ZIP-compressed, make sure your iPhone can handle ZIP files. If not, install an app that can, such as iZip (shown below).

NOTE
Most of the sample programs appeared in the books HP-55 Mathematics Programs (2/75) and HP-55 Statistics Programs (5/75).
These programs are identified by a signature at the bottom, e.g. (M-142) would mean "Mathematics Programs", page 142.
A very few were modified for easier use, taking advantage of the larger program memory of RPN-55.
