Hello Max,

Some turn into rather sticky stuff reminiscent of old chewing gum, it probably depends on the storage conditions.

i have attached 2 pictures. Can you tell from the pictures what condition they are in?

When I got the HP-25, the feet were more or less nasty black. I cleaned them with gasoline and now the computer sits really well on the table or even once on a sloping dashboard of a car, where it did not slip away even in curves.

A first attempt with a screwdriver I have broken off again, because I had nevertheless concerns that the rubber breaks with further levering in pieces. :-)

   
   

Thank you for the rubber link.
