That's a quite different one. Pascal's Calculator was a
rather simple mechanical calculator that could only add
and subtract numbers. Once the design was finished, it
was quite easy to actually build it. I wouldn't call it
a "computer".

The Machine that Charles Babbage designed almost 200 years
later was meant to tabulate polynomial functions, and it
was _much_ more complex. It was a beast consisting of
25,000 connected gearwheels. And that was only his first
design; it was followed by even more complex ones.

In fact it is true that his last design of an "analytical
engine" (the first programmable computer ever, though
never actually built) was intended to be powered by a
steam engine, so the OP was right. :-)
