- Well cbm's Lew said it will have chunky mode without losing its bitplane
- nature. take that as you might interpret it. But at 8x and up of
- the aga bandwidth, your writepixelarray8() should be mighty speedy.
- Then if they have it hardware fixed for that () it should be nice,
- but even without chunky in the deep hardware it shouldn't be bad.

- I would like to know where we stand as the a4000 doing the writepixel
- compared to a graphics chip that is primarily chunky?
