The NEC PC9801 took an alternate approach--it had two
graphics
controllers in the machine, so graphics and text were handled
independently and could be superimposed on the same screen.
As did the DEC Rainbow. The colour video card for that machine was a
completely separate system to the built-inmonochome text display. If you
used the standard cable with a colour monitor you got the text appering
in green, and the colour graphics. With a special cable you could have
text on a mono monitor and sparate colour grapgics on a second monitor.
