I have to take issue with this statement, Frank. :)

Super Extended Basic on the Coco3 can and does use more than 64K whenever you 
use the high res text or graphics screens. There are quite a few programs that 
combine Basic and ml programs to use the full 512K memory.
As already stated by others, OS-9 can easily use 2Megs of memory but 
unfortunately the operating system itself can't use more than 2Megs.

Keep in mind the boards by Paul Barton that had 8-16Megs of memory. So any new 
"Coco" should have at least 2Megs.
