I agree.  They were going with low pars count, and banking into the 32kB 
RAM bank was an easier task that banking on 8kB pages

That said, I looked at the article this morning (thanks John) and then 
looked at the Coco1 and Coco2 schematics.  The kicker is trying to get 
the VDG and the CPU to see your new RAM.

Would it be horrid if the situation were simplified a bit?  Say, let the 
CPU see megabytes of RAM, but let the VDG stay in the original 64K map?
