OT: need to drive a vector CRT...

Try to get an HP1350 or HP 1351 graphics translator, or graphics
generator. These are not all that
hard to find, and they generate excellent quality vectors, driven by a
GPIB interface.

Very cool, real vintage vector hardware!

And by the way, NO raster based display can ever do a credible job of
simulating a 'real' vector
display. The aircraft cockpit had ~real~ vectors, not a raster display,
and for a good reason.

Use real vectors, accept no substitutes.
