Presumably you mean the Harvard Mark I as there were a series of them up to the Mark IV. Can you say why it is wasn't Turing complete? The requirements for completeness are modest (putting aside the far from modest assumption of unbounded resources) so the reason for failing would be significant I think. (It's hard to find enough details on the web to settle this by simple searching -- I did try for a bit.) <snip> -- Ben.
