- I suspect that these numbers are with promotion turned on. 640x400
- 31khz 8 bit ham has the chip memory bandiwdth totally saturated (like
- 16-color hires before, except with twice as much data to move). 640x400
- interlaced will provide transparent cpu chip memory access, which
- should dratsically increase the frame-rate.
