[Coco] How does the cartridge port work, anyway?

[Allen Huffman]

I have wondered this for ages, and thought this might be a good place to ask...

Could someone explain how the CoCo cartridge port works? How are cartridges able to show up as memory locations in that final area of the 64K?

And, perhaps, in terms a software guy with little hardware background could understand?
