At the moment, it is hard to see a good reason for a 62Meg RAM disk 
(2Megs are used by OS-9). Still, this seems to be the first use of 
memory beyond 2Megs either on a real Coco or an emulator. It proves the 
memory can be used. Now it's up to others to see good ways of using it.

How about a very large graphics screen. Certainly there is enough memory 
to hold a jpeg image. Even if the Coco or emulators can't display high 
bit images, they could pan over a two or three screen flicker image.

A real NitrOS-9 burn-in test would be a full checkout of the RAM by 
filling every byte with at least four values, $00, $55, $AA, and $FF and 
reading them back to be sure they took. Still, such a test took less 
than 5 minutes on a Nocan3 8Meg board so a 64Meg system should finish in 
under an hour.
