Bill,

That's what I thought but grabbing the lsb of regX seemed peculiar. Maybe the 
following will ring some bells in your memory. ;)


The current status is that the crash occurs after the ENTER key is hit. That 
means you can type anything and see it appear on the screen until you hit enter.
While it might seem that setime is the problem it is not. You can hold down the 
shift key during the boot process and get to the OS9: prompt. Type anything and 
you will see it. ENTER will crash the system.

I can't quite pin down what is crashing but it looks like we are very close to 
working in 6309 native mode with a coco1. Once NitrOS-9 runs, then code can be 
optimized for the 6309.
