Another thing you might want to think about, is that A3000 DMA can
DMA into FAST RAM. That has NO chip contention. So if you're
worried about DMA contention with graphics screens, don't.
As far as I know, the DMA contention only mattered using SEVERE overscan
HIRES screens. And at that, I don't think it was enough to be a problem.
I think it was originally a problem with the original A2090 hardware
or software, but probably not a real problem anymore.
