I have a copy of some of the content that was produced for JMJ's 1995 Rendez-vous concert in Paris, Much of it was produced in DPaint on an ST, and I'm certain Trip-A-Tron was mentioned. I know that a STOS program was written for some of the animation stuff...
I would have thought an Amiga would have been a more obvious choice, or at least a Falcon, but the ST was 10 years old at the time, I guess it shows it's a capable machine.
