Touchy subject?

I'm having to support old weather data visualization software, similar  
to what's still being used at National Weather Service Offices around  
this country,  in our university computer lab environment. This  
software has been the mainstay for classroom meteorology instruction  
for at least the last 2 decades.

Probably because it is scheduled to be phased out, the developer group  
(still active; has no interest in converting the  
8-bit'ness to truecolor.  Since it has always been a simple task to  
provide  pseudocolor via a simple xorg.conf entry, it has not been a  

Given that, what would one do to determine whether or not this video  
card/monitor combo in the iMac is going to do pseudocolor?

What would the Section's and Subsections want to look like if  
pseudocolor was available? (I thought I knew; maybe it's changed)
