[Coco] atari USB device

John

The only way to handle the large packets and gain adequate 
"effective" speed trransfer is to offload software in the Coco to a 
dedicated processor within the cartridge. 

Some means of DMA will be needed to stuff packets in ram 
somewhere both the USB cartridge and the main processor can 
access. The Coco can be modified to 2 Meg of rather easily.
