Which I kinda find odd. I thought ACube wasn't going to sell any hardware that didn't come with OS4. Now it does, so does that mean the old agreement/contract is no longer valid?
ACube have always said that they sell their boards to industrial customers; this is just the first time that they have provided a price up-front. Everywhere else they say that prices for the industrial version vary depending on volumes, and that you should contact them.
