Hi Tim,
Identical but not the same board?
I'm asking because I guess it is possible that one board isn't running at the correct speed....wrong x-tal populated for example.

PBP wil run faster than PBPL since the math routines will be 16 bit instead of 32 bit (doesn't matter if you're actually using LONGs or not). So if you're relying on a specific routine taking x amount of time then you can see a difference (depending on what the routine in question is doing) but if your using PAUSE or PAUSEUS there shouldn't be any difference at all.

/Henrik.
