I suppose they would (i don't see why not), but I am interested in the best one that would work under native OS 9, yet also be fully capable in OS X with QE/CI support.
ClassicHasClass's suggestion looks good, although I'd like to say that I'm not necessarily after a card with lots of VRAM (and such cards, particularly for these older machines, seem to be more expensive).
Also, I just realized something: I have an ADC display hooked up to it right now, and a non-Apple card will not have a port for such, so then I'd have to get a ADC to DVI converter. Ugh...
Are any G5-era cards with ADC ports known to have driver support under OS 9? Are any known to be compatible with the MDD G4s?
This is becoming somewhat more complicated than I anticipated...
