Possible improvements to HP15c firmware

overlay_-_1What could be improved on the HP15c CE by changing the firmware?

  • Back up: in my opinion, the ability to write down user memory (including memory disposition) would be fantastic. not only you save your hard-entered programs, but you could store different profiles (EE, algebra, finance, others...) and change them "on the fly"
  • Memory is now far less important - we have enough! there are some methods to bring it to 224 registers, but what's the point?
  • Debouncing time adjustment - a little like screen contrast?
  • Any other that you can imagine?

Being able to switch modes between 15C and 16C without a reset would be nice, especially while saving the user memory separately for each mode, so that my programs in each of the modes would stay intact. That would go along nicely with your profiles idea which I also like.

Since it is possible for the HP-15CE to have multiple personalities, an HP-12C mode would be fantastic along with a keyboard overlay for it.

In my book, the possibility to backup and restore memory would be fantastic. Imagine that you could write an debug your programs on your real computer and just upload it to your 15c when you're happy with the code.
