Second, it was the first machine to feature any kind of an index register, a facility that was quite widely copied. You can trace the influence from the spread of the Manchester name for the facility: they called it the "B-tube", a reference to the internal structure of their own machine. (Already having an "A-tube" for the accumulator, and a "C-tube" for control registers, they used the first free letter.) And if you read through the computing literature of the '50s, you'll find frequent references to index registers using terms like "B-boxes", which are otherwise inexplicable.
I tend to find that is the case. Us brits tend to be less brash and more modest than our US counterparts.
On the flip side, we tend to be called unfriendly because of it!
I do agree with the opinion expressed in the article, though, that the British contribution tends to be downplayed. But as a brit myself we're used to that...
The Manchester Baby is in the science museum here in Manchester and its worth a look if you somehow find yourself in Manchester. The long-now talk is interesting, but you might want to fast-fwd past the stuff about canoes and tree houses.
