I'll wait until Howard sees the rest of what you said before commenting on it, but I can answer to this part. There are two problems with doing what you ask here. One is board space. The other is signal integrity. Whenever you route a signal to more than one place, you end up with reflections from unterminated ends, and these signals for the highspeed DAC are already routed to two places. Keep in mind that if OGA has more than one head, what it can do won't be identical to OGD. If you're really intending to use OGD as a graphics card, you're wasting your money, or you're willing to spend the extra money for the highspeed DAC (which, relatively speaking, isn't all that much). We decided it was more important to have the option for high-speed analog. Of course, as you point out, there are lots of other "options" we didn't include. It's really hard to set priorities with so many unknowns. We just need to get something out that serves our purposes and has sales potential of its own, so my opinion is that we should get this design debugged and produced so we can move on to the next step. Perhaps I'm being impatient, but dangit, I want to have an open source graphics card in my computer! :) _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
