New Never Used HP41CV ?

[jftman]

Yeah looks clean throughout. In transit from overseas, Morocco.
Eager to get a look at the terminals for being clean, I hope!

I keep buying the 41C with intent of making it a donor to one tgat has a dead flex circuit over the terminals, but end up finding the donor calculator in better condition overAll.
Not complaining!

As an aside here.
Why after removing the batteries on a 41Cv does the stack register maintain data?
How is continuous memory, in that respect possible, without a battery for any time period?
That therefore says the chips are turned on, and retain their state?
Is this volatile or nonvolatle memory?
Then do these chips have a cycle life? Like a USB drive would, after millions of switching?
