- Yeah, we've gone after VESA standards for XGA and are quite willing to
- sell the design and rights to it. I know that Intel bought the XGA-2
- rights. And XGA still has a lot of room to grow and expand. The original
- shipped with 0.5Mbytes of VRAM -- systems are now shipping with 1Mbyte of
- VRAM. And the old code still runs on the new design.
-
- Would there be interest from game designers if we were to put together
- a bunch of sample code for doing some operations? If I can generate
- enough interest, maybe management would approve the effort to collect
- some of the sample demo code we have sitting around.

- Hmmm, XGA-2 has a hardware sprite 64x64 pels and does 16 bit direct
- color graphics (i.e. 65536 colors) at 800x600 with a 60Hz noninterlaced
- refresh rate. And with VRAM support you don't have to sacrifice all your
- bandwidth just to refresh the screen :-)
