Y'know, we all keep saying this, but so far without any detailed
knowledge to back it up.  Does anyone know for sure just how Amiga-
dependent the Toaster is?  Mostly the interface software, or ?

The Toaster uses the amiga custom chips for much of it's data
manipulation. That is part of the reason why it sits in the video slot.
The toaster hardware as it now exists could not easily be ported to
another platform. It would require redesign around other graphics
chips.

I want to qualify what I am about to say by saying that I really don't know
for sure myself. What NewTek have said in interviews is that the toaster
makes use of some of the custom chips in the Amiga to do some of the magic. I
would make a guess and say either the copper, or the blitter, or both.

If you do a digital transition effect with the toaster, what you see on the
AMIGA control monitor is a coloured screen with weird lines and boxes moving
where you see the digitaly compressed screen moving on the TOASTER monitor. -
that is, as you scale/flip the toaster screen, something in the Amiga's video
hardware is doing SOMETHING that shows up on the screen - looks like some
kind of weird interference pattern, and the TOASTER software blanks the
screen while the effect is taking place.

As another piece of the puzzle, consider that an A3000 can use the Toaster if
you take out the Denise chip, and replace it with an OLD Denise chip from
another Amiga model (2000 series, whatever). This indicates that the Toaster
uses some talent of that chip to do some of it's work.

I've heard from NewTek that their going to release a Stand Alone Sorta Black
Box with a Toaster in it.  Since I live near NewTek I also heard that their
going to release their own computer or actually a Amiga 2000 with a toaster withabout 5 megs....
So the black box should solver the compatablity prob with Amigas....
