A kludge added by "CU@STL" in the version that I picked up allows the use
of an environment variable ("FRAMEBUFFER") to override the default
"/dev/fb" framebuffer to dump (FRAMEBUFFER should be set to "/dev/cgfour0"
on a 3/60C.) A better way would be the "standard" way that Sun
applications do it: use a "-f" option on the command line. The best way
might be to look at the "overlay enable" plane and choose the colour or
monochrome planes based on this (on a pixel-by-pixel basis.)

Available in the sun-sources archive on titan.rice.edu is "psraster"
(don't for get to get both the original source and the patch!) This is a
wonderful little program which, will handle 8-bit deep rasters and the
conversion from Sun rasterfile format to Postscript. It has (as far as I
could tell) all of the functionality of pssun and more. Try it, you'll
like it!
