The MIST is now being sold fully assembled, ready-to-run and with a nice little case. You might order your board e.g. at Lothareks Lair in Poland, Dragonbox shop in Germany, Amedia in France or AMIGAstore in Spain.
This page was used during the initial development. With the board being available for sale the documentation and code also needed a new public home.
Thus the main information source for the MIST is now the mist project at github and its wiki. New MIST owners may want to read Getting Started.
Most discussions are taking place at the MIST/Suska sub forum on atari-forum.com.
