Don't forget, however, that you will somehow tell Display Postscript
that the monitor in use is not a color monitor, or the outputs will
have to be separated.  In essence by attaching a grey-scale monitor
to a color board you are mapping colors to a set of grey-scale representations
behind the back of Display Postscript.

Short-circuiting DPS will mean that you can no longer assume a
uniform representation when you program, unless again the DPS
is made aware of the characteristics of the monitor.

To an extent, variations in the color monitor make this problem
as well, although they tend to be more subtle.  RasterOps and Radius
have Macintosh products to color correct color monitors to make the
computer color representation agree with the actual color representation.
