Of the monitors I have, there is mold or ??? under the

the screens of:
* ADM3 Terminal (or ADM3A, don't remember)
* Soroc IQ120
* HP Terminal (don't recall model)
* DIGITAL monitor (don't recall model, but 12" or so screen)
The HP Terminal was stored in a station wagon, others were stored in the
garage and back porch. I don't remember seeing mold on any monitors used
for the IBM PCs or Apple computers. The weather here is mostly moderate
all year long, and I am about 3 miles from the Pacific Ocean.
Do the ADM3 / Soroc / DEC screens obviously have a faceplate whilst the
IBM / Apple ones don't?
I'd just like to rule out that it isn't purely that the affected
monitors have faceplates whilst unaffected ones don't! (implying that
the rot is common to the transparent sealant used in that sort of time
period, rather than it being a specific type of sealant that only some
manufacturers used)
At least the problem seems to be fixable through the hot wire method -
although one person's reports way back of the CRT being damaged using
this method is a little worrying.
If I get time I'll have a look at which of our non-HP screens at
Bletchley have been hit by this - the next time I'm over there is
already scheduled to be a completely manic day though!
