[Coco] Hidden 256-color mode

In doing the VDG section, I am not limited to 15KHz horizontal 
frequency. In fact the first pass will be 640x480 and at 31KHz 
horizontal frequency.

Ethernet can be done with an external chip as well as USB. What is 
really needed is a means of doing DMA and burst writes to ram 
from devices such as ethernet and USB.
