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

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.
