Yes-- and they were pig-slow. (I used PLATO in the late '70s, and even
then it felt slow to me.)
I used it for a grand total of one class around 1982 at the university
of illinois, where it was all dreamed up.
How much of that was due to the slow write times to the pixels vs. the
fact that hundreds of terminals were hitting the mainframe driving it
all over serial lines?
You could probably make a coincident-voltage memory
from them... but
they'd be slow I think, but pretty.
Not all that slow. The first plasma panels -- invented at the
University of Illinois and used in the PLATO system terminals -- used
the display pixels as memories.
