I don't have the Motorola Manual so I've resorting to posting here-

1. I get a NaN(255) after my program runs for 1-60 seconds. Its very
irregular and I'm pretty sure I'm not dividing by zero or overflowing.
Does the '881 give a NaN when you underflow?

2. I need to use the '881 during interupt time. I know it needs it's
environment saved and restored somehow.. how do you do this?

I like you get mail but maybe you should post to the net (too?).
