  Yes, it's composite video, but not NTSC. (far higher resolution than NTSC)

  I don't know if something that recent will drive it at the right sync
rates, but you'll find out quickly enough if it doesn't. ;)

  Let me know what cables you need when the time comes; it's likely I've
got it.

  Significantly higher-end than that.  The framebuffers it was designed
to work with drive it at 1024x864.  It was commonly used in 1-bit
displays, but 8-bit grayscale was doable also.

  Oh they're very much for graphical use.  They were used for bitmapped
graphics displays on VAX workstations, targeted at CAD applications, but
frequently used for regular GUIfied workstation tasks as well.

  I sat in front of one for years, on a VAXstation-II/GPX, running in
grayscale mode.  It was one of the sharpest displays I've ever used.
