Hollerith 1890 tabulating machine with sorting box. [a] Hollerith punched card. The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...

Regulators found weaknesses in "living wills" submitted by four of the country’s largest banks detailing how the lenders would wind themselves down if something catastrophic were to happen.
Introduced with System/360 in 1964, the 029 had new character codes for parentheses, equal and plus as well as other new symbols used in the EBCDIC code. The IBM 029 was mechanically similar to the IBM 026 and printed the punched character on the top of the card using the same kind of mechanism as the 026, although it used a larger code plate ...
