Exactly. I recall some real-time applications that used CGA to
graphically display the state of a process and MDA as the text-mode
interaction with an operator. From a programming standpoint, beats
the hell out of (small "W") windows interface. Some early CAD
systems, I believe could also do a similar thing.
