"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. -Frank McConnell
