Music boxes weren't programmable in the sense that they allowed for a different algorithm to be performed. They changed the timing of certain operations. >Or perhaps only things that can have branch instructions count The author identifies programmability as the most interesting metric, which creates a "computer". Branching is necessary for that but not sufficient.
