[Coco] NitrOS9 bug

[Barry Nelson]

I have found an interesting bug. If I create a disk using NitrOS9 level 2 and install and run the game Cave Walker, it will run on VCC, BUT if I take that same disk, and try to run it on a physical CoCo, it locks up before the game's graphics screen loads. The computer does not respond to the keyboard at all, including the break and clear keys, only a reset restarts it. I checked using the CoCo SDC and two different floppy controllers and got the same result. I also tried two different OS9Boot files. Next I will try Radio Shack OS-9 level 2 and post my results.
