- But this entire pronouncement is based on the assumption that you
- just happen to be using a number of bitplanes that exactly matches
- the depth of the chunky display. In other words, artificially
- dismissing the one factor which is the sole reason why anyone ever
- chose planar in the first place.

- BTW, Jay Miner once told me that if they'd done the A1000 a few years
- later he would have used VRAM for the chip memory. If they had done
- that as the first significant upgrade to the chipset, like maybe
- around the time they were working on the 3000, we wouldn't have had
- to wait nearly as long for better depth/resolution performance...
