If we define a computer in very broad terms: a system used to emulate/simulate another system, could we call a wind tunnel a computer? It is a system that is used to infer what would happen high up in the atmosphere or on the race track. Taking it a step further, do animals used for drug testing count as computers? They are used to infer any potential adverse effects in a human body.
Although quite specialized, I think these things would still classify as a computer.
