Well, yes, but I'm being pedantic. Partly I think that the Manchester
machine may get more attention than it deserves (at least I'm biased in
favor of the elegance of Zuse's and Wiles' designs).

You are right. But if one just wanted the effect, one could get it from the
Z3 -- well, get it after waiting a horribly long time for the program to
run, anyway. :)
