Video Toaster working on Minimig

[alexh]

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

Autoconfig ID = 2191 / 0

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

The video toaster sets in the Video slot. There is no way it's a Zorro II card. But 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.

It's correct that the TBC cards sold for the Toaster just used the Amiga ISA slots for power. Those were controlled via the serial port. There's a header in the 2000 where the first card connected, and daisy chained to the rest. You could put the same card into a peecee of that time just as well. They usually came with software for both.

No, you are wrong. The Video Toaster just uses the Video Slot. It is NOT a Zorro II board. Take a look at the pictures.

You do need a parallel port for a video slot though, which the current implementation of the MiniMig doesn't have.

@mongo:
In what way does it use the parallel port?
(how many signals?, speed?, onput? output?)

The core of video toaster doesn't seem that impossible to do entirely in HDL.

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.

original videotoaster have autoconfig ID but toaster 4000 dont.

wth? maybe ID its for flyer, not for toaster itself.


200 bucks they say? i still wanna try this card just for fun

Toaster 2000 (original toaster) is a Video Slot card

Toaster 4000 (AGA toaster) runs in either the video slot or the extended video slot (You need to change jumpers to correct configuration)

Flyer is a Zorro-II card.

Toaster 1.0 runs on a stock 2000, 2.0 would too, though pretty slow.  

The video slot is basically the 23 pin video port, the parallel port, audio ports and some power pins.   The toaster loads video frames and other items by some very clever code using this interface.

I'll defer to Tigger on that, I never saw a 4000 Toaster. Mine's the original model. But I suppose the web site just listed the autoconfig info for the newer model and assumed it applied to all of them.

Howcome Toaster 2.0 become slower in the same enviroment as Toaster 1.0 ..?

A Mini-MIG toaster version would be best if it used the Flyer and Toaster 4000 board with an AGA chipset version of the Mini-MIG

For those unfamiliar with the toaster. It takes the AGA output in 256- or ham 8 and overlays it onto video. You can switch between a Live camera, live video off a SatTV or Cable box, or PC video NTSC output. You only need a Time Base Corrector for sources coming off tape or Macrovision protected DVD players.

TBC's can be external or internal.

I used a Toaster Flyer setup for nearly 10 years and it was great. I'm at a point where everything minus the live switching can be done infinately faster on a laptop.

The Flyer allows comibnation of switching live and non linear editing, and playback live on a set. You get storyboard editing from the factory settings and there are plugins that enable a timeline of sorts.

It was so impressive that an investor plunked 4000K to buy a second sytem for us when he saw what it could do.

Aside from lightwave you can use low speed 030 as I ran the toaster with the A3200 030 card. I did have a CSPPC233/060 but that helped only with rendering clips, the CSPPC hd controller did speed up the slight processing time required before the flyer played a project... but you can get by with modest CPU power.

I renderd all my lightwave stuff on the PC and burned the flyer clips to CD-ROM and copied them over.

NOWDAYS...For live switching I used NewTek's Tricaster, its a direct anscestor if the  TOASTER FLYER housed in a shuttle PC. It's made by NewTek.

Discreet FX is on the right track as this technology was never used in Europe and it'd be a blast to see what demo coders can do with it. Especially since toater 4000's are cheap these days.

What most folks don't realize is that you can used them with existing PC and MAC systems and even as a live switcher for a internet TV webcast. I used to record the flyer output directly into a mac laptop using an analog to DV bridge in Imovie, re-encode and upload!

Actually putting the toaster and flyer and mini-MIG into one FPGA would be great. You can have a self contained unit on just a few chips in a small package. Imagine a Live switcher VJ mixking- MINIMIG the size of an external hard drive enclosure.

Great technology...
