Thank you for the very informative article. I referenced it trying to figure out a problem in my emulator. One note that might be helpful to others is that in the "Formulas for the overflow flag" section it wasn't completely clear to me that in the "(M^result) & (N^result) & 0x80" formula, the N is ones-complement of the target, not the target. It took several readings and much comprehension to give that a try.
