It will work in the 1.1/1.2, but B9C has not yet developed settings for anything other than the Core machines. Based on my contact with them over the issue, they felt that since it's main advantage in the Core would be speed for prototyping, there was no need to develop 1.1/1.2 settings, as the black serves the same purpose. It never occurred to them that 1.1/1.2 users might want it instead of black for the color. They have said they are looking into it; whether that means they intend to create settings, or that they're just thinking about it remains to be seen. Most of their communications do state that users are free to experiment and develop their own settings, but they have yet to even state what a rough starting point for that experimentation might be.
