At the beginning of 2024, the PX41CX was not yet available on any website, neither as a kit nor assembled, as there were only two copies.
I had the privilege and great fortune to have one of these two prototypes since Alex trusted me to test this true gem.
I used it daily and found an HP "Pioneer" calculator case that fit it like a glove.
I was such a fan that I eagerly awaited the final version's online release!

But we had to count on Alex to surprise us with a completely different version with an improved keyboard, a USB port, and many other new features.
Several of us were able to use this PX41CX in advance, and it eventually went on sale.

In 2025, the PX calculator series was expanded with a new model...

Perhaps we should talk about two new models, since the PX-Voy can emulate an HP-15C or an HP-16C, depending on the option.
To adapt the keyboard's key indications, simply unscrew the front panel, turn it over, and then screw it back on.
Of course, a USB port allows connection to a PC (or Mac) for firmware updates and memory dumps.
Many other features are also waiting to be discovered...
