There is software that takes advantage of the 6309's enhanced features that are not available in the 6809. Additionally, some (all?) of the 6309's instructions are optimized, so they run a tad bit faster than in the 6809. If for no other reason, the 6309 can provide a slight speed boost. I've read here that a 10% increase in speed is realistic. Salvador

Since the 6309 normally works like a 6809, why bother?
