026 was for Boy Scouts, running a mailing list on an IBM 403 printer. We could program the cards, and the keypunch drum card, and the 403's paper tape, but only a few adults knew how to program the plugboard wiring on the 403. (Or girls who took Secretarial Data Proc in school.)
The 029 was for college, and I think the punches I used at Bell Labs were 029s, until I got my stuff to run from IBM terminals. (I also used PDP11 and later VAX and mainframe Unix on ASCII terminals.) A Labs guy named Eli knew the JCL so we always copied his.
