[rescue] cd-rom rot

[Robert Toegel]

Well, the only reason I mentioned it was that I once read that when they
upgraded Hubble, the computer was upgraded to a 486 and we were beyond that
on Earth.  The story was that the more modern chips were much denser so a
cosmic rays striking a newer chip would more likely change something than
would happen in a 486.  Just wondered if the same logic applied to floppies
all else being the same (not cosmic rays but just random noise or loss of
magnetism).
