We were into real-time simulators running on SGs (from Impact, Octane through to Onyx and Power Onyx ). Produced real-time vis sims for the MoD (here and in Norway), Schiphol ATC and Flanders docks pliots amongst others. The biz went tits up at about the time SG were trying to move onto PC-based and they never quite got it right. We actually ended up using PC Quantum 3D boxes - sure they've gone too now
Is all that in english?
