How did they map the 32k into the CoCo 3 address space? Did they have any special hardware in the pak besides the rom chip? How did the CoCo 3's addresses map onto the address space of the rom? How does all this relate to the layout of a 32k .ccc file?

There is a complete description on this subject in "Breaking the 32K Barrier" by 
Greg Zumwalt, "The Rainbow", June 1990, p58.
