Can't speak about the Grinnel, but in the early

a site that had some nice Megatek (IIRC) stroke graphics engines that include
a conic section generator so it could do curves and circles and stuff.
Was this a storage tube, calligraphic tube or raster tube?
'Course, for all I know that was standard

It depends on what you mean by stroke graphics hardware; the Tektronix
401x series is a storage tube device that is "painted" by strokes, but
it doesn't have anything more than point, line and character output.
You have to build smooth curves out of line approximations.
