Which would that "specific purpose" be? Even punch cards have alphabet interrupted between R and S. And the whole punch card -> 8-bit is pretty illogical, just like the cards themselves. How come no punches in zone don't correspond to 0 high bits? (and don't get me started on punch card.. it started with "let's do 1 hole per column for digits" - OK, makes sense; then "let's do 2 hole/column for uppercase" - I guess OK but why did you put extra char in the middle... but then it's 4 holes/column for superscripts? 3-6 holes/col for punctuation? If someone were to design punch cards today but using same requirements, they could easily come up with a much more logical schema)
