Imlac/Hazeltine Dynagraphic terminals?

[Josh Dersch]

Anyone have any idea if any Imlac/Hazeltine Dynagraphic terminals are still
around?  I've never heard tell of one beyond marketing information.  These
were late vector-graphics terminals made by Imlac Corporation after they
got bought out by Hazeltine in the late 1970s.  Any technical docs
(programming, architecture) would be interesting to look at.  And if anyone
knows of one hiding in a basement somewhere...
