[Coco] Writing a virtual GPU / FPU device.

I kind of have exposure to virtual devices via the OVCC project that allowed
me to investigate how the dynanmic device modules are designed.


Now I would like to create my own GPU / FPU device.


I would like to know how device designers chose the memory addresses to
where the device maps its registers.


Of course I don't want to conflict with any other devices!


Is there a list of memory addresses used by all other devices?


The Tandy CoCo Service manual provides all the standard device mappings but
what about third party?
