I was siting down with my parts the other day and discovered that the OM software requires a Duemilanove. I have a Diecimila and was going to switch out the processor to a 328. Will this work in the short term for testing? I have a Duemilanove on order but nothing ever happens on time or overnight! I have pretty much every thing else I needed. I know there are a few things different between the 2 boards mostly just convenience stuff I think.
