I'm thinking that 026 and 029 keypunches could be had with several
types of keyboards. "Numeric" would only have numeric keys, because
if numbers are all you want to punch then giving the operator the
ability to easily punch letters and figures opens up all sorts of
possibility for error. "Combination" would have a full keyboard that
could be used to punch letters and figures as well as numbers.

The 029 could be had with two different character sets as well, one
commercial and one scientific. The differences were only in the
keycap legends and what was printed on top of the card though; the
same key positions produced the same punches on both.
