Sure, but the poster on comp.terminals is making it sound like if
you've used a VT100 for any reasonable period of time, this will have
happened to you. They even go so far as to say that if you turn on
your VT100 you should leave it on until the next power bump.
That sort of advice just sounds fishy to me, as I've not heard of
this being said about a VT100 before. But hey, I could easily be
wrong. I'm looking for confirmation of this behavior ON A VT100.

It seems not a matter of reading, but reading it with a wrong VPP
voltage applied or something like that. As stated, this is a design issue.
