Is an organ really in the 'computer' class of machine? It doesn't "carry out an arbitrary set of arithmetic or logical operations," to quote the Wikipedia definition. A barrel organ could be said to follow a 'program', if we're loose enough to mean 'a set of machine-readable instructions that cause a process to take place' but it is in no sense calculating a result based on logical operations.
