3D News, GL, DirectX With the Open Graphics Project advancing slowly a few students picked up the idea to do it all smaller, faster, and more importantly, cheaper. From the site: "We'd love to have an OGD1 card and are amazed by it's specifications, but for us and a lot of people, this card is simply too much. So that's where this card comes in, to give you all the fun of developing on programmable hardware, designing video cards and architectures, for a price that won't hurt your wallet."

1) You can get a PCI interface wire-wrap card with most of the PCI interface logic included.
2) Get a standard SVGA graphics frame buffer chip (ET4000 from mid-90 should work.)
3) Get a low-power PPC or 68000 cpu.

You could then use a open source OpenGL library to implement a graphics language on the card. You could also move all or part of the X-Server to the card.

I'm not sure why everyone wants to create their own SVGA interface; thats the hardest part here. Also, they insist on creating some sort of custom graphics engine; when an off the shelf RISC type cpu will work just as good.

Can you tell me where to get these PCI ready cards if they don't cost a arm and leg like the few I have found?

Personally I just want a huge frame buffer that looks like a single block of memory to my OS, the difference is that there would be multiple outputs each feeding only a quadrant of the frame buffer out.

The move from one to two monitors was great, three might be better but I think I need 4 or 6 monitors acting as a big screen would be seeing a real improvement.

It would be nice to have a single card giving support for 4 or 6 outputs.

Funnily enough thats all I really want from a graphics card too and feel blessed I can even use a basic $50 twinhead card at all on BeOS or W2000 for that matter.

Even nicer if the video ram was partitioned into smallish tiles with a decently fast and open spec processor per tile and software configurable as to tiles per monitor head. Still the perforamce bottleneck would still be the PCI unless one steps up to PCIe hardware interface or keeps all the rendering in the card, buts thats another project......

Even at the low end of FPGA cards, some of the ready made edu Spartan cards have a VGA output but no DAC so they are stuck with 640.480 with 8 or 16 colors, way too retro for me. As soon as these development boards get even remotely interesting, their prices go through the roof and they pick up features that are of no use to me.
