In addition to the video slot, the Video Toaster also needed a Zorro II slot.

To make it work with MiniMig you would need to expand the RAM to 10Mbytes, add a 68030 CPU and implement the BUSTER chip inside FPGA, maybe use a larger FPGA for the extra I/O's that go with that.

Not feasible.

I will yeild to your superior knowledge. There seems to be a lot of pins on the boards edge connector for just video.

How does the Amiga set up the Toaster without CPU access?

Is it just "on" all the time?

The blurb says "Realtime transitional effects including Dissolve, 2-D Wipes, Colour Amimation Wipes, Covers, Slides, Oragnic Effects, Digital Effects"

How do you activate and time these effects without Amiga CPU access to the Toaster? Switches?

TBC = Time Base Corrector (some sort of video module)
ISA = Pre-PCI I/O card, I guess the TBC's sit in them but just to draw power.

The more you look at the OpenToaster website the more it makes me think it must have had a Zorro interface. Otherwise how did all this software interact with the hardware? Simply though the video output?

The ISA slots are not connected to the Amiga hardware without a bridge board. If they are used by a part of the Toaster Hardware or addons it's for power only.

Confirmed, Argus is wrong. All video toasters must have data connections to the Amiga.

http://amiga.resource.cx/exp/search.pl?product=video+toaster&company=

Autoconfig ID = 2191 / 0

If they have an Autoconfig ID then they must be memory mapped.

if you look at the specs for the video slot, there is a lot more there than video. In addition to all the video signals from the DB23, there is the parallel port data. That's how the Amiga controls the Toaster.

Oooh, "you're right jim".

I wonder why they are listed as having an Autoconfig address? Maybe I dont know how Autoconfig works, I thought that they were just Zorro related.
