It's not the 12C, it is the very new 15C Collector's Edition. As a NOMAS (NOn MAnufacturer Supported) feature, It has a secret menu that can select between two different memory sizes for the 15C, or the 16C. You can find more information about it in these forums. Because it's NOMAS, please don't ask HP, Moravia, or Royal about it.

Technically the new 15C CE firmware, with the NOMAS features, can run on post-2015 HP-12C calculators, but as there is no hex file of the firmware publicly available, it's not a practical option.

Note that the NOMAS 16C functionality has some fairly serious issues, also being discussed in these forums. Again, please do not ask HP, Moravia, or Royal about these issues. The only source for information about NOMAS features is the user community. It is presently unknown whether the 16C issues will ever be resolved, or in what form a resolution might be made available.
