42S with nonvolatile RAM - Lyuka - 12-10-2013
Long time no see.
I just made modifications of an HP 42S to make its memory nonvolatile by using an F-RAM. It seems successful so far.

I am envious. Not of the calc, but of your knowledge and abilities. Thanks for the inspiration.

Dear Lyuka,
you cannot imagine how many times I have visited your web,
your mods are so well documented.
I am curious, how many 42s's do you have???

Thank you for your compliments.
Actually I have two defective 42S (and two other flawless one, of course ;-)
I really think 42S useful, and for they were defective, I had no hesitation to modify them.
