The software house is Integraph, both systems are right dogs to use & really require 2 screens. Modern 3D packages put this gear in the shade but many multinationals, quite understandably, bought the Integraph stuff as soon as it came on the market...because that was what everybody was looking for. They can't throw that size of investment away lightly: but one day they will have to.

This is no criticism of Integraph packages: just a suggestion that you do not break a leg chasing after training packages.

For personal use you might want to search one of the software arcades of any major Asian city. ■
