I bought an HP 2621a CRT computer terminal in 1980. But about fifteen years
ago the screen got black spots like mildew. But it ain't mildew. Apparently
the glue holding a plastic sheet over the glass is decaying. I looked online
and found you have to peal that plastic off and remove the glue. I do have a
Zerox (ok, it was Savin then) copy of the service manual, but it says nothing
about this. Yeah, it's nostalgia and prolly not worth the effort. But would
appreciate any tips from anyone who has done anything like this before.


I have not done the process, however I do advise you wear protective
clothing (heavy leather/armoured apron or jacket and gloves) and a full
face shield that protects your eyes and neck when working with picture
tubes. They can be very dangerous, in close quarters, if broken...
