Yes, I did know, but as far as I am aware, SIMH support is currently only
for the QVSS graphics controller used by the VAXstation  I and II which is
monochrome only. For my interest (software archeology of digital mapping
systems), I need the colour graphics capabilities that came with the QDSS
(Dragon chipset) in the VAXstation II/GPX.

Mind you I'm currently finding that the current Cygwin/X seems to have lost
the support for 8-bit pseudocolor modes (colour maps) that I need and was
in it a few years ago, so I'm a bit stumped there also.
