Public Beta Availiable - Win/Firmware

While you can post in forums such as this at your discretion, we ask that the primary way of reporting be to send reports to Basically, the goal is avoid disruption or annoyance to other forum participants. You can pop up a pre-populated email template by clicking the "Report Issue" menu item in the programs themselves.

Currently there are some issues around the Mac build being resolved and also android/ios.

This beta is different then others done in the past. There has been a disruption for many reasons in our prior development, and there is a slew of many changes and features that had been worked on and are in various stages of completeness. Some might be 100% done and good, but lacking some documentation. Some might be functional ans mostly done, just needing debugging. Some were experimental. Some might be utterly not yet done.

We ask you to play around with it and really help find out what you like, dislike, is good, is broken, etc so we can try to get things stabilized and ready for release as soon as possible. This is in essence a much earlier snapshot then things that have been released publicly in the past. Maybe if things go well we can continue doing things like this.

Special thank you to Eric Rechlin at for hosting the files for us.

More complete release notes and some documentation can be found at:

Cyrille's first thread:

Have fun!

**Note that the revisions and dates may not be 100% correct. Some information in the notes may not be correct and changed later as we tweaked stuff. There were lots of changes made, but many a long time back and may be not fully baked yet... just go with it Smile

Lots of changes in program editor (apps or programs). (open MORE menu in program editor, UI not great, but functional)
  • Line numbers in program editor
  • Bookmarks in program editor
  • Multiple files in program editor
  • No need for pre-declaration of functions
  • Able to have multiple functions of same name with different number of arguments (no default arguments though)
  • Embed resource files (binary, jpg/png, python source, cas source)
  • Go to line number
  • Mark a program as read only source (Avoid accidental editing)
  • Encrypted program source (hide source, still be usable on systems)

Connectivity Kit: 2.1.14542 (2021 04 13) BETA

This BETA release of the Prime Calculator firmware and associated PC and Mobile software delivers fixes to outstanding issues. This document is not a complete list of all changes but highlights specific items. Only users willing to experiment with pre-release software and report issues to are invited to experiment with this release.

Please back up your calculator before the update. Any existing data on the device may be wiped during the update process. This beta is much less polished then any you had before.... you have been warned. "Here be dragons"
