The punch and its companion, the IBM\u00a0 59 card verifier, were used to record and check information in punched cards. The cards were then read and processed by a computer or an accounting machine. The IBM 29 remained in the product catalog until May 1984.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The machine is easy to operate, quiet, and attractive. One\u00a0 of its most important feature is the simple means of setting it up quickly for automatic control of duplicating operations, automatic insertion of left zeros, or skipping. Each setup or program is made by punching a card and mounting it on a program drum, which is inserted in the machine.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">On the 29 Card Punch, with unlimited use of two program levels, each program card can contain two totally different, complete 80-column programs. Either program can be selected for card to card use by setting a program selection switch. If it is desired to use both program levels to control punching on a single card, alterations from program to program can be made by program selection keys on the keyboard. Programs can be alternated at will, while punching a single card, by means of these keys.<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text el_class=&#8221;museum_video&#8221;]<iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/YnnGbcM-H8c\" width=\"600\" height=\"330\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_separator color=&#8221;white&#8221;][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;831&#8243; img_size=&#8221;large&#8221; el_class=&#8221;museum_item&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1610942974450{border-top-width: 0px !important;border-right-width: 0px !important;border-bottom-width: 0px !important;border-left-width: 0px !important;padding-top: 5px !important;padding-right: 5px !important;padding-bottom: 5px !important;padding-left: 5px !important;background-color: #000000 !important;}&#8221;] Model: IBM-29 Developer: Clair D.
