[Coco] 64K Mode

[Brad Grier]

If I put a coco2 into 64k mode and then build and display a screen 
somewhere above memory location 0x8000, what would happen if I switched 
back out to 32k ram as the screen was being displayed? Would I see 
garbage on the screen or would the image persist?

The reason I ask is I'm working with a game that puts the intro screens 
in high memory and then rapidly switches out and back in to 64k mode 
while waiting for user input. I'm not sure if the game is synchronizing 
the bank switch with the display somehow or if the screen simply 
persists from 'high' ram perhaps until a new screen mode or offset is 
defined.
