The Toaster is on the video slot which is basically the 23 pin video port, the parallel port and the two audio channels (plus some other lines) on a slot. I can't imagine how the mediator could effect it. The Flyer is basically a complete computer on a card hooked to the zorro-II bus (and uses very little of that bandwidth), so I dont think it likely the mediator will effect it either.
