Nope, USG was only ~1/3 the market for supercomputing back then. There were lots of industrial uses for supercomputing (e.g. computational fluid dynamics calculations to design tires that hydroplaned less, flame dynamics to create more efficient engines, finite element analysis to model parasitic effects in semiconductors, ..) However the market for the TMC was indeed almost exclusively the USG (or research departments at a few large corporations, and a few universities) because no one could figure out how to program it for something useful - as mentioned before, it was really, really hard to program anything more than a really constrained scenario on the CM.
