Jevons's Logic Piano has already been presented in several publications. It was the first hardware devoted to logical inference. In this paper we propose a new view of that machine in the frame of Finite States Machines. Indeed Jevons's Logical Machine is a set of finite states transducers with a Single Instruction Multiple Data organization. This allows it to evaluate some boolean formulas with N variables in space proportional to 2N and in constant time.
