Many applications using unit record tabulators were migrated to computers such as the IBM 1401. Two programming languages, FARGO and RPG, were created to aid this migration. Since tabulator control panels were based on the machine cycle, both FARGO and RPG emulated the notion of the machine cycle and training material showed the control panel ...

SDTM (Study Data Tabulation Model) ... Identifier variables, which identify the study, subject of the observation, the domain, and the sequence number of the record;
The Works Records System at ICI developed in 1974 on IBM 370/145 [39] ExecuCalc, from Parallax Systems, Inc.: Released in late 1982, [40] ExecuCalc was the first mainframe "visi-clone" which duplicated the features of VisiCalc on IBM mainframes with 3270 display terminals. Over 150 copies were licensed (35 to Fortune 500 companies).
In 1963, it got even better when the addition of a magnetic strip made it possible to record audio along with video. New cassette-based formats would soon render both 8mm and Super 8mm films obsolete.
