Hi there, hope you've all had a fun weekend.
Some time ago, taking advantage of the temporary price dip on used models when the Limited Edition was introduced, I treated myself to an original HP15C from 1984. When the package arrived, there was a big smile on this old boy.
On the outside, the calculator in mint condition. It passes the tests and works fine.
But when I flip it around or give it a light shake, there is a slight rattle. It is not related to the batteries. Since the body is so clean, I feel uneasy about opening it up, as I'll probably scratch it.
Wondering if others have had the same phenomenon, and would be able to share some insights on what is causing the rattle?
Thanks much!
Wishing you all a beautiful week.
