A group of professors here at Indiana University are in the process
of selecting computers for running experiments using visual stimuli.  
Our needs range from modest to demanding --
the most demanding is real time animation of high resolution, shaded 3D
		      ===================	              =========
objects,  the least demanding is animation of low-resolution 2D objects.  In
all cases, we need to collect reaction time responses from subjects.
This probably requires real-time workstations.  Does anyone have
recommendatios regards to our requirements?  Our burget is somehow
limited to be about 4 workstations with a prices tag of less than
$20,000 per unit.  My main concern right now is to find out what's
available in the market in our price range and get some details
about them. 

We're interested in any
and all information we can get, regarding configurations, compatibilities,
caveats, endorsements... We're starting from scratch. 

Please e-mail me the responses if possible.

Thanks very much.

Actually, this is available on our low-end Personal IRIS machines with
the Super graphics option.  It is not demanding at all for an IRIS - real time
movement of Gourad shaded 3D objects is what the machines were built to do.

Of course, 2D is a primitive subset of 3D ...

The educational discount on a Super 4D/20 with minimal memory and disk should
fit right into this price range (contact a salesperson for details).

Our sales force will be happy to give you all this stuff.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO vs IBM.
