I bought a BitScope for this purpose on one project, and have used it ever
since. If you want to see data over a long period, this may not be for you -
it doesn't have a tremendous amount of memory.
Then again, if it's free you want, it's altogether out.

I think I could write a VB program to display a pair of lines in text in an
hour or two. The hardware shouldn't be too hard either....Of course a full
analysis would be a bit more involved....

What were you rollin' that made you look elsewhere?
