Vlad, why don't you write a graphical FSM generator? Textbook FSMs are quite powerful, but in practice, states and transitions are usually augmented with enter/hold/leave actions. This provides plenty of configuration potential. Also, there's a (...) (26 years ago, 14-Dec-99, to lugnet.robotics.rcx)

Hi again! I was looking at the Handyboard, and thought whether it would be possible to port IC to the RCX.
