500 V2+ On An A2000 With a ZZ9000 Card

My current setup is an A2000 with an '030 and a ZZ9000 RTG card.

I'm just wondering if anyone has tested a Vampire 500 V2+ on an A2000 with the ZZ9000 solely used as a de-interlacer and DIGITAL-VIDEO out, ignoring it as an RTG card?

Thank-you.

considering the numbers of vampirized amiga 2000, I don't think anyone tested this setup before, I also doubt it will even work.

The only output the A500 Vampire V2+ card can do right now is RTG via digital video, so ignoring it as an RTG basically means you wont get any output.. (until core3 comes but right now nothing has been promised).

Well if I select a video mode that's OCS or ECS I have a video output going through the RGB connector. That said, in theory running multiple video cards is a thing that Amiga can do, just select the output via the video mode selector.

In principle it should work.

I was thinking on the lines of just using the ZZ to output the video when the vampire is not using its RTG mode. Saves me some money from buying a flicker-fixer/scan-doubler from IC.
 
Now looking at that external link, is Matt using the Vampire strictly as an accelerator and ignoring the vampire RTG while using the RTG & video from the ZZ? And the Vampire's RAM is allocated and usable?
 
That's a thought.

  Right but I think the o/p wants to run those over digital-video not RGB.. and right now thats a no-go unless you use the alpha core3 .. which hasnt been updated in some time..

if you dont want to use the OCS/ECS modes via digital-video and are ok with RGB then yea (in theory) it should work presuming you can interface it

I am using my ZZ9900 with the Vampire 500 V2+ as I type. I switch between the Vampire GFX and the ZZ9900s's GFX from time to time. I have two different installs, each on it's own Compact Flash Card. One card has the Coffin OS installed using the VampireGFX and the Other card has OS 3.9 using the ZZ9900 graphics output. The native Amiga output via the ZZ9900 works fine either way. Since the Vampire is an all in one card, the memory will available to the system regadless of what Video output you choose since it is integrated onboard, tied to the CPU.

Allan, how much slower is the ZZ's graphics vs the Vampire? Is it a  noticeable difference? The Z2 bus is pretty slow.

I run most apps in 1280x720 8/16 bit. It's definitely not as fast as the Vampire, especially in 16/24 bit modes but it's not horrible either. It's as fast as most graphics cards on the Amiga 2000 as long as you keep the Workbench screen resolution and depth to 16 bits or lower. But still, it's OK and doesn't stop me from using it. Especially when the Amiga's native output is used, the ZZ9900 switches automatically witch is very convenient. I can leave my DIGITAL-VIDEO switch on the same input unlike when I use the Vampire.
 
The Ethernet is nice and fast as well (in-line with other cards I have). The  last update resolved the hideous 25KB/s transfer speeds, now I get around 600 KB/s. I have not tried the ZZ9900 yet on my 4000 since it has no case at the moment. I bought a defective motherboard off of eBay a year ago and finally got it working :) It would be nice to see the difference in graphics performance between Zorro 2 and Zorro 3 with the ZZ9900.
 
  I hope this helps...

Based on what exactly?

I have a vampirized A2000 with a ZZ9000.  I use it also for the scan doubling.  Both with and without RTG.  It works fine.

There isn't a simple answer here.  The Vampire has blindingly fast access speed to its own frame buffer.  So for mpeg playback and raw pixel writing speed, the vampire RTG is king.  However, the ZZ9000 has an ARM processor on board which accelerates drawing operations.  So in desktop operation, you might not notice the difference so much...........until you switch to 1280x720 or higher.  Then you start to see the screen redraws on the ZZ90000 when flip between screens.  Here the Vampire RTG is much better.

For me the promise of the ZZ9000 is in the on-board ARM processor.  Off-loading things like OpenGL drawing operations to the ARM processor could be very interesting.  Whilst not currently supported by the A2000 version currently (and I assume this applies to the A500 version as well), offloading graphically intense operations to the ARM processor is a very interesting proposition.

Vampire CPU + ZZ9000 could be a killer combination in my mind.

For some reason I refered to the ZZ9000 as the ZZ9900. Sorry about that. Cheapest upgrade ever :)

I will be more than happy to test this kind of configuration in my A4000T+ZZ9000 when a Vampire card will be available for A4000 :-)
