	We have recently integrated an HP7550 color plotter with
our VAX780 and are generating good color graphics with it. However,
it also appears that some of the graphic operations require extensive
HP-GL (HP's graphics language subset) code writing, especially in
creating math symbols and letters in their 'polygon' format.  Oversized,
solid-color lettering is good for lecture style vugraphs.  Having no
desire to re-invent the wheel, especially since I would probably have
to cut its corners, I was wondering if anyone had managed to create a set
of routines for the plotter or knew of a commercially available
library for making vugraphs and scientific plots on an HP7550A unit.
Thanks in advance.  Address: Bob Thayer, MIT Plasma Fusion Center,

problems getting a 7550 to work on a VAX, the hook-up specifications
detailed in the HP manual work for SOME applications, beware.
