I am trying to port an essentially black-and-white application (which
nonetheless worked on a Sun 8-bit color server) to an 8-bit
DECstation 3100 server, and am having many problems.

I've managed to pin them down server specific things, e. g.:
1. I can't create a 1-bit deep top-level InputOutput window when the
   depth of the root screen is 8, although I should be able to.
2. When I go around this by making all of my windows 8 bits
   deep, but copy into them from 1-bit deep pixmaps using CopyPlane, the
   result I get is totally wrong (old window pixel 1: pixmap pixel 1: plane arg 
   to CopyPlane 1, GC plane mask FFFFFFFF, result window pixel 0).

Is there something obvious I am missing here?  This server (Xcfb) is brand
new - does anyone know how reliable it is?  Things seem to run on it,
but so did my application elsewhere up to now.

I would be glad to contact DEC about this, but it's a big
organization, and I don't want to again get into shouting down a
-30dB SPR pipeline . . .  Knowledgeable people read this newsgroup -
do you think you might provide a pointer?  Thanks in advance.
