I don't think Tektronix ever made a terminal that
wasn't graphics
capable :-) and when they went to raster displays from storage scopes,
I believe they were all color capable.
I remember at least on counter-example, the 4025. It was a
mono raster unit. We had a 4025 at the research lab of the
first company I worked for out of college. It was connected to
one of those electrostatic printers. We drove it from a VAX 11/750
running BSD4.2 and later 4.3.
