Depends on what you mean by ?buffered?. In a sense,

is the buffer.
What I mean is an attached memory buffer and controller that could
refresh the display without the intervention of the program that created
it. In those days, if DSD died, you looked at a blank scree, not the
last display "frozen".
If you mean buffered in the sense of a buffer near or
in the
controller, containing data that pretty much directly encodes the
display primitives, then that doesn?t apply here. (Well, not unless
you?re looking at the ?K display? ? where an application program
could ask for a more or less arbitrary display by supplying something
very similar to a ?display list".)
Well, we called it the "T" display (we had a lot more displays for our
specific TCM-based system than SCOPE or MACE). :)
