At Vesalia http://www.vesalia.de/e_indivisionaga4000d.htm there are some photos of the Indivision 4000D. If it will be available on march, surely the one for A1200 will be too ?
Indivision AGA 4000D/CD32

Flickerfixer for Amiga 4000 and CD32


The Indivision AGA 4000D shown in the picture is a prototype board, the actual product available in March will be blue instead of white.



What color the Indivision MKII is going to be? Blue? In white they match with my new ACA1230/56...

Is there anything particular you guys want to write for Indivision ECS, or is it something like: "release the docs, and maybe someone else will do something for it" ?
Not sure I understand your question above, but I would like to learn more about Graffiti on the Indivision. I was/am a great fan of the DCTV and understand that Graffiti was the same thing, or very similar, though I have never seen Graffiti in use. I would like to see DCTV and/or Graffiti make a come back, as they are very low resource hungry way to get more colors with high animation speed for games or other video, or animation type applications.

What maximum resolution do you think will be usable? Is 800x600 in 256 colours too much to ask?
something wrong with this picture ?

No, it's a valid question.. Oliver from Individual Computers thought so, and answered that exact question by saying:

What I believe they are discussing is the Indivision ECS which has Grafitti Emulation and the new accelerator together. Grafitti has a max of 640x256 with 256 colors. (I think, don't have a Grafitti or Indivision ECS)

So, the question is, with the new accelerator and the IndiECS, could it be increased...
Oliver thinks, maybe.. ;-)

Almost correct.

Indivision ECS does have Graffitti emulation, but it doesn't make sense, since on ECS, Grafitti is VERY SLOW and works only in 320x resolutions.

That's why Indivision ECS has its own new graphics core, which allows direct writes into the chunky framebuffer of the flickerfixer at full speed, without chipset interference. Not only is this very fast, but resolutions up to 1024x768 in 8 bit or 16 bit (downconverted to 12 bit) are possible. This core has nothing to do with the native Amiga display, it's a core which turns Indivision ECS into a very small graphics card, capable of Zorro II speed, with native chunky graphics support.

So Cammy has not only realized what Indivision ECS can do, but also anticipated my intentions what to do with it.

Somehow I have missed the info that new revision of A1200 scandoubler will maybe be faster in HighGFX at 256 colors.

Current version is very usable at 1024x768 with 8 to 16 colors (or highres with 32-64 color WB) with 060 IMHO.

Can you estimate roughly how much faster the rev 2 will be at 800x600 or 1024x768 full 256 colors... I am considering upgrading if it is a bit faster

I currently run 32 color background in 64 color high-res WB and it is very fast with 060 IMHO, check it out -> [ Show youtube player ]

Speed is limited by the chipset.
Indivision is only able to display given data.
And this has to be done by the amiga-chipset.

Yep it looks like only Grafitti can save AGA

Yes, I hope March.

Would like to know if the prize will be the previously stimated after the problems they had with the prizes of the ACA630

Hiya Jens,

I'm currently building a new 1200 for the Mrk2, any chance of some prototype pics so I can see how it will all fit together. If not can, you confirm that it will roughly be the same physical size as the Mrk1?

Thanks

It'll be a bit smaller than the first version, because I want it to fit in the A4000T. My physical model currently looks like this (green board was a prototype of the first version).

I really hope the indivision aga 2 will fit better then the previous one and not pop off Lisa, and hopfully this one will give a crystal clear picture...

I don't pretend to understand the way Graffitti works, except if it is the same as DCTV it works with bitplanes, not chunky graphics and I know that some time in the very early 1990's at an Amiga show I saw an A3000 running a complete movie which had been converted a single frame at a time to DCTV format and it ran full speed from the hard drive with sound. Probably Anim5 format I guess, but it looked every bit as good as a (typical for the time) VHS tape being played back. I am sure it was not limited to 320 resolution, it was full NTSC resolution.

I would love to see the DCTV or Graffitti display make a come back for Classic Amiga game animations. I don't know why more programmers did not use DCTV or Graffitti to get more colorful games back when both display devices were first released.

Of course if Oliver can get us a fast chunky display from our ECS Indivisions with 8bit or 12bit color depth, that might be a better solution. Any news to tell about your progress Oliver?

I think it's all very exciting and was one of the big things missing from the first Indivision AGA IMHO. There's a whole load of games that would benefit from a Graffiti mode when this comes out and I'll be happy to do some of the updates


Come get some! (clue)
