Obviously, you would run your C-to-Turing-machine translator over it,
producing some Pascal initialization statements for your Turing machine
emulator that you wrote in Pascal. What could be simpler? :-)
Truth is, not only is it not the case that all computer systems are
effectively Turing machines, none of them is! It's those damn finite
tapes, for one thing. And computers are always hooked up to input/output
devices. (A computer is something that controls and monitors machinery.)
But discounting all that, don't we care just a little bit about how long
