IMPROVED DATA ENTRY

Year Published: 1960s

Creator: International Business Machines

Description: This IBM promo film "Improved Data Entry with the IBM 50 Magnetic Data Inscriber and the IBM 2495 Tape Cartridge Reader " dates to the era when magnetic tape was supplanting punch cards for data entry. The film introduces the IBM System/360 and the IBM 50 Magnetic Data Inscriber, designed to increase data entry speed by using magnetic tape instead of paper punch cards. The inscriber features a versatile keyboard and program level selection. The film demonstrates loading the tape cartridge and selecting programs, highlighting the keying process and error-checking features. Additional keyboard features and the completion of data inscribing are discussed. The verification process, including the use of a verification code, is explained, followed by a description of the IBM 2495 Tape Cartridge Reader, which reads data into the computer and allows for continuous operation. The versatility of the tape cartridge reader and its compatibility with other IBM equipment are emphasized. The film concludes with a summary of the benefits of the IBM 50 and 2495, including the fact that it is at least 25% more efficient than a card punch, and highlighting improved data handling techniques,. The IBM System/360 (S/360) is a family of mainframe computer systems delivered between 1965 and 1978. System/360 was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large. The System/360 family introduced IBM's Solid Logic Technology (SLT), which packed more transistors onto a circuit card, allowing more powerful but smaller computers. 00:00 - 0:16: Introduction with applause. 0:16 - 0:37: Introduction of Kathy, a key punch operator, and the IBM System/360. 0:37 - 1:04: Introduction of the IBM 50 Magnetic Data Inscriber, designed to increase data entry speed. 1:04 - 1:38: Explanation of the magnetic data inscriber, which uses magnetic tape instead of punch cards, allowing for continuous keying. 1:38 - 2:23: Description of the inscriber's features, including a keyboard with character set options and program level selection. 2:23 - 3:01: Demonstration of loading the tape cartridge and selecting program levels. 3:01 - 3:53: Keying process and error checking features, including quiet operation and quick error correction. 3:53 - 4:58: Additional keyboard features, such as record backspace and automatic left zero function, and the process of completing data inscribing. 4:58 - 5:37: Verification process, including the use of a verification code and sending the tape cartridge for processing. 5:37 - 6:43: Description of the IBM 2495 Tape Cartridge reader, which reads data into the computer and allows for continuous operation. 6:43 - 7:55: Explanation of the versatility of the Tape Cartridge Reader and its compatibility with other IBM equipment. 7:55 - 8:22: Summary of the benefits of the IBM 50 and 2495, highlighting improved data handling techniques. 8:22 - End: Closing applause and music.

e [Applause] [Applause] this is Kathy a typically efficient and hardworking key punch operator the key punch installation and IBM system 360 and Kathy make a pretty indispensable team there is however an important new addition available to this team IBM will show you the system 360 user how increased throughput and greater versatility can be achieved with the installation of IBM 50 magnetic data inscribers the magnetic data inscriber is designed to minimize the time lag in data entry by dramatically increasing the speed of getting data to the computer IBM had the operator in mind too when designing the magnetic data inscriber by making it not only attractive but with minimum orientation easy to operate the characteristic difference of the data inscriber is that it does not use Punch Cards data is inscribed directly on magnetic tape in system 360 code each cartridge holds 100 ft of magnetic tape and has a capacity of 23,000 characters permitting two to three hours of continuous keying with a single cartridge the magnetic data inscriber allows system 360 customers to achieve an average throughput gain estimated at approximately 25% over card punches the keyboard on the inscriber offers as a standard feature either 64 or 48 character set usage under switch control eight alternate programs are standard with a program level selected by the operator seen through the window on the console the IBM 50 program card mounted on a programmed drum controls the operation of the inscriber with the programed drum in place the operator now loads the tape cartridge the Magnetic Tape cartridge is inserted on the spindle it is removed here and reinserted to demonstrate ease of handling the onoff switch is conveniently located on the console when the button designated right is depressed the machine is put in the inscribing mode and the tape is threaded automatically to select the program level desired the program select key is to pressed first then one of eight digit Keys corresponding to the program desired is depressed automatically rotating the program drum to the selected level now the IBM 50 is ready for keying one feature of the data inscriber of particular interest to the operator is the quiet operation of keying data keying error suspected operator sensed errors can be checked quickly to change from inscribe mode to read mode depress the read button indicator lights on the character display show the last character keyed confirming whether a keying error has been made in this case the digit two is displayed to press the button designated right to return to the inscribe mode when an error is suspected it normally takes less time for the operator to rekey the field rather than check the suspected key error this is done by depressing the field backspace key automatically returning the tape to the beginning of that field the data is then rekeyed other keyboard features both useful in time-saving are the record backspace key which automatically Returns the tape to the first character of the record and the automatic left zero function a standard feature of the IBM 50 automat machine functions duplicating and skipping operate at 100 characters per second when data inscribing is completed and the tape is ready for verification the rewind button is depressed this automatically records an end of data mark on the tape prior to rewinding if additional recording is desired on the tape the search button is depressed automatically moving the tape to the end of data Mark which indicates the end of previously recorded data verification is a standard feature of the IBM 50 however verifying is normally done by a different operator to put the inscriber in the verify mode the verify button is depressed automatically threading the tape and selecting the program level the verifying procedure is similar to that of card verification the same program card may be used for verifying and inscribing the operator verif veries data previously recorded and also corrects errors to verify corrected data the operator must rekey only the data in the corrected field every verified record has a special verification code automatically recorded by the IBM 50 when the end of data Mark is reached it signals that the last record has been verified with verification completed the tape cartridge is sent to the computer room for processing the system 360 checks each tape for the presence of the verification code the tape cartridge reader the IBM 2495 reads this data into the computer at 900 characters per second the feed station of the reader can hold up to 12 cartridges as cartridges are readed others may be added without interrupting the operation of the equipment operating buttons and lights are located ated conveniently by depressing the start button the tape reading process begins the lead cartridge drops into read position it is then automatically read rewound and stacked in approximately 60 seconds a partially inscribed cartridge requires less time cartridges may be removed from the stacker without interrupting the reading process these cartridges are reusable to inscribe new data the IBM 2495 tape cartridge reader is attached to the multiplexer channel of system 360 the 2495 can also read tapes prepared on the IBM Magnetic Tape electric typewriter the mtst all of this means that the tape cartridge reader provides added versatility for system 360 customers together the tape cartridge reader and the Magnetic data inscriber are significant examples of IBM's improved data handling techniques a commitment to provide management with a new dimension of service and efficiency in data entry the IBM 50 working with the 2495 a new way to process information [Applause] [Applause] a [Music]
