The MC-II is the only one that fits. Sadly, that's one that isn't currently slated to be picked up in the currently licensing deal. I'm hopeful that maybe in the future it may happen, it all depends on how much volume there would be. I'm glad I stocked up on the MC-II boards before they disappeared as I have a number of projects that I'll need them for. I just wish I had more MC-ACC boards, I didn't plan far enough ahead on those.
