6309 microprocessor project:

Hello,

So far my design for the memory and hardware of the coco3x emulator consist
of:

 1. Virtual FFxxH memory giving you total control over the virtual hardware
plugged into the emulator.
 2. Virtual Multi-Pak support allowing four 16K/32K bank switched rom/ram
cartridges.
 3. NoCan 64MB interface virtual hardware device giving 16MB memory.
 4. Very fast speed when changing memory because pointers are calculated and
not EMS BANKS
      being mapped in/out of the program address space.
 5. All the original virtual device drivers are available to insert into the
virtual FFxxH memory giving
     a nice default system that starts up exactly like coco3x version 1.9.
 6. Ability to design and test virtual hardware devices for the coco3x
emulator.

More later.

John Collyer
