2540 had punch on one side and reader on the other side with five
stackers in the middle ... two for the reader, two for the punch and
middle could be used by both reader and punch.

one of my first programming jobs at the univ was class registration
... still done in the gym with tables for classes and sense mark cards
... which are then interpreted/punched. large number of card trays
(about 3000 cards per tray). read card into middle stacker, validate the
card information ... and if there is problem, punch a "blank" card
behind it (card punch loaded with colored cards).

later problem cards can be identified in the trays by colored card
punched behind it.

virtual (ios3270) green card (converted to html) reader/punch CCWs (says
3504, 3505, 3525, similar for 2540, but select three stackers)
