For pixel graphics... you may be able to subclass the PSET/ LINE
commands but I don't know. Maybe someone working on the MVT100 thingy
can speak to that.
The PSET / LINE, etc. graphics primitives in the ROM have no hooks and
only work with the internal LCD. I looked into that when I was
thining about my TDock project many years ago.

Well shoot. I guess I would be only supporting ANSI then. I guess it
isn't that terrible. A larger screen would mostly be usable for large
texts like writing code, etc...
To support graphics, I could of course have all of the primitives on the
display side which would then only be compatible with software written
specifically for it.
Even though finding this exact display might be difficult, there are
plenty of controller-less LCDs similar to this out there for relatively
cheap. Any controller designed should be able to work with most of them.
The standard is typically 4 bits at a time, this one supports 8 bits at
a time for the two planes. The timing signals appear to be pretty
standard as well. The point of that thought is that sharing the project
for others wouldn't be useless if they could use it with other panels.
