There is one more problem with trying to make Drivewire HDBDOS work with Coconet 
Drivepak on a Coco3. HDBDOS is an 8K ROM while Coconet is a 16K ROM. Coconet 
flips back and forth from all RAM to all ROM to read the top 8K on a Coco3. That 
means you can't have HDBDOS in RAM, Coconet in ROM, and alternate between the two.
Coconet tests the RAM/ROM state and changes it based on the Coco in use. A Coco3 
will return to RAM mode and crash if HDBDOS is there.
