I'm not sure if this is the same as the "Prevue Guide" that we used to have on our local cable in Kingston, Ontario (Canada), but it sounds the same.
I always suspected that the guide was Amiga-generated, and then one day I was flipping through the channels and it had guru'd and was blinking away at a software failure message
It was stuck there for a long time, so I put a fresh tape in the VCR and set it recording... I managed to catch its whole bootup process on tape! :-D
