[praatika@mappi.helsinki.fi]

This is probably not the reference you meant, but anyway, the relation 
between Babbage's engine and Turing computability etc. is discussed also 
here:

Gandy, Robin (1988) “The confluence of ideas in 1936”, in: Rolf Herken 
(ed.) The Universal Turing Machine. A Half-Century Survey, Oxford 
University Press, Verlagen Berlin, 55-111.
