DSI 327, 8 Fields of 10 Columns each

 [Very generic punch-card]

This is an example of a typical generic card, widely used both by programmers and for data processing. The printing on the cards can be thought of as dividing the card into 8 fields of 10 columns each, with each columns subdivided into 2 5-column fields, or a programmer might think of the rulings on the card as helpful tab stops for dealing with the indenting structure of free-form but deeply nested programming languages such as Algol or PL/I. A high resolution scan is available.

 [University of Illinois punch-card]

Aside from its institutional imprints, card has only one interesting feature -- two separate boxes, each with with column numbers, for the textual interpretation of the data punched on the card. The topmost box, 80 columns long, is positioned around the area where interpreting keypunches print, while the bottom box, broken into two lines, is positioned around the area where off-line interpreters print.

 [Princeton University punch-card]

Aside from the change of institution and the omission of the ruled boxes around the areas reserved for interpretation of the card, the design of this card serves all of the same purposes as the Illinois card shown above.

MIT Information Processing Center

 [MIT punch-card]

This card has essentially no interesting features other than the rather ugly overprinting of the classical MIT seal over the punch position numbers of a standard generic card.
