I might be remembering this incorrectly, but I believe DEC's VXT2000
(or maybe the VXT2000+) was an X-terminal product that shared some
technology with the VAXstation 4000/VLC.  If they both use the LCG for
graphics, I'd not be too surprised if the hardware was designed with
support for Xwindows in mind.

It might be worthwhile to get your hands on a copies of the network boot
and firmware images for the VXT2000.
