	I would dicker with the not cheap comment. Ever heard of interleave?
I also made this comment, until I realized that if you delay ram timings
through interleaving, You don't need fast rams.

	I definately wan't to see this! Guess I'm off to Comdex!

	I looked at my obsolete A2000 schematics, and looked at the update
leaflet on it. The video connector doesn't bother me, but the Extended
video connector does. Raw audio? Is it the rummored removal of the audio
cutoff filter? If so, will the form factor of this add on not interfere
with the extended connector so some other card can exist in it's slot?
Or will it pass/propogate these signals if it does?

	So I can solve my no A2000 monitor problem by buying one now?
If I have to, I'll get a SONY since SONY knows how to do overscan better
than ANY company I know. You know, FULL picture to the square corners.
