AFAIK the 026 was useful only for S/360 predecessors, and the 029 was
the first supporting the S/360. An 026 ) + ( = ' were treated as < & % #

my decks to the S/360 equivalents. As to lower case, it was possible,
but not pleasant. The 026 and 029 will produce overpunches if you firmly
press down on the card while punching, preventing it from advancing to
