A short question: is it possible to undo the "Clear memory"-
option on a HP48SX?

I've noticed that clearing it's memory is an incredibly fast 
process. My guess is that not all the memory is cleared - 
just the pointertable. I wonder: is it possible to make a
program that saves away the pointertable and prints its own 
entry in the table. My idea is that to "restore" the memory,
you should just restore this number in the pointertable
(how?), run the program (which should now have reappeared in
the user menu) and - voila! - your memory is back.

Is this just fantasy? Is it an easier way to do it? Please
email me about it!!
