[NTLK] Darkening spot on Newton 2100 screen

[DoctorClu]

Thanks Abraham,

     Appreciate your response back on the 6th.  For some reason I am not 
getting this list through my email, and this message did not show up on 
the newtontalk.net page till I checked today.

     What you say is what I've heard over people say.  The thing I'm 
curious of, could the polarizer be replace, but the touch layer be saved 
and reused?

     Thanks you and all,

     Greg / "Doc Clu"

That sounds like vinegar rot aka polarizer pox. The glue binding of the
screen layers decomposes and basically you get this.

Unfortunately, there is no easy solution. Usually you would carefully scrap
the polarizer and replace it, but here you also have the touch layer to
contend with, and those may be more difficult to find.
