Another major development by Univac in tabulating equipment - the Selective Posting Interpreter. This highly versatile machine senses information from a selected master card in a group of master cards, retains the information, and prints it out on every card that follows. By control punching, sensing is suppressed from all other master cards. Once a setup has been made, it will be retained for printing on all cards until cleared by control punching. There are no limitations to the number of detail cards which can be printed from each master card group. (Univac advertisement, Datamation, July 1961, "20 From Univac," #15)
