The IBM Type 012 tabletop key punch (1925) was the first model capable of
duplication; that is, automatically copying columns from one card to another.
Left: What appears to be a Type 012 Electric Duplicating Key Punch in the
Crystallography Lab at the California Institute of Technology. The only
puzzle is it seems to be handling 80-column cards with rectangular holes
(see closeup),
which were introduced in 1928, whereas the 012 pictured above uses 45-column
round-hole cards. In any case, it appears that this punch was procured for
the lab through a request from
Linus
Pauling to IBM's Director of Pure Science,
Columbia's
Wallace Eckert in 1947.
