File Feed
A file feed with a capacity of 3600 cards. is provided as standard equipment. The file feed automatically joggles the cards as they are fed into the . hoper, thus reducing the amount of manual joggling to a minimum. Cards are fed by the high speed vacuum assisted feed mechan-ism surely and accurately without a card weight.
Brushless Card Feeding
The sensing of holes in a particular column is accomplished by a movable one- watt light bulb, which may be rotated to read any column desired. The light shines from beneath the card, through a hole in the card, and onto a light-sensitive diode. The card is then directed to the appropriate stacker by a chute bla.de. The light source should be cleaned daily with a dust cloth. Any adjustments to the sensing mechanism should be made by a customer engineer. If a card jam occurs which requires removal of the sensing mechanism, call a customer engineer.
Do not attempt removal of the mechanism your-self.
Radial Stackers
Cards are sorted into 13 radial ~tackers,
each with a capacity of apprOXimately 1650 cards. Instead of cards being stacked face down, as in other types of sorters, they are stacked on the column 80 end, with the face of the cards toward the front of the machine. Cards may be easily removed from the stackers with-out stopping the machine.
OPERA TING SUGGESTIONS
If you must correct cards by placing patches over the punches, be sure the patches are
opaque. The photoelectric sensing mechanism will read through a translucent patch.
Oil spots on cards should be avoided, since application possibilities of the machines. While you are not expected to be. an expert on all these features, there are certain ones that you should be familiar with.
Auxiliary Card Counter
An electrically operated card counter can be mounted to the left of the feed hopper to count
While the card counter is normally used for counting the total number of cards that pass vice versa, depending upon the method of selec-tion employed. For example, if the type 83

MACHINE ACCOUNTANT 3 & 2 Cards may be edited on the types 83 and 24
sorters. during . a selection operation without disturbing their sequence. With the sort selection switch set to N and the edit stop switch and
$ort suppression switch ON, cards are sep-arated and errors fall into the reject pocket in sequence with other rej ected cards. The edit stop switch will stop the machine when an error card falls into the :rej ect po cket.
Still another use for the sort suppression device on the types 83 and 84 sorters is check-ing a scheck-ingle column for blanks or double punches without disturbing the sequence of the cards. Set the sort selection switch to N, and turn the edit switch and sort suppression switch ON. Cards punched with only one digit will sort into the 12 pocket, while double punched cards or cards not punched will sort into the rej ect pocketo Setting the edit stop switch to the OFF position allows continuous card feeding without causing the machine to stop each time an error is detectedo
Alphabetic. Sorting Feature
An alphabetic sorting feature can b.e installed on the types 83 and 84 sorters to speed the operation of alphabetic sorting. When this device is installed, the sorting patterns normally established when the sort selection switch is set to A-I, A-2, and A-N are ch,anged permanently.
The sorting pattern established by this device is shown in figure 5-15. This pattern is based
on the frequency that certain letters appear in proper. names.
Alphabetic Sorting. To sort a column alphabeti-cally, all cards are fed through the sorter once and a part of· the cards a second timeo On the pockets zero through 9 respectively. Cards punched with B, D, F, H, j, M, P, S, V, and Y sort into pocket 12, while those punched with K, N, Q, T, W, and Z sort into pocket 11.
Blanks, and cards not punched with an alphabetic letter, sort into the rej ect pocket.
On the second sort, change the sort selection switch to A-2, but leave the sorted cards in Re-move them in ascending· sequence from pockets zero through 9.
Alpha-Numerical Sorting.-Cards which may contain either letters or numbers can be sorted by first setting the sort selection switch to A-N. The digits 0-9 sort into pockets 0-9 re-spectively, and all other cards sort into pockets

CHAPTER 6
INTERPRETERS
You have learned that data processing ma-chines read cards by sensing the punched holeo It is possible also for you to determine the contents of a card by reading the punched holes, but this is a slow and tedious pro cesso Inter-preters are designed to read the holes punched in a card and print the data across the card.
This makes it possible to use punched cards for many applications which would otherwise re-quire the use of printed forms. For example, rotation data cards can be machine prepared, interpreted, and forwarded to activities for recording of data on personnel that are due for rotation. Muster cards, statement of leave cards, paychecks, and many other types of cards can be prepared and interpreted for use outside the data processing installation. You will find many uses for interpreting within your own installation. Each file of cards you main-tain is usually interpreted in some manner to provide ready reference to the contents of the cards. Interpreted cards provide assistance when you refer to a file for a particular item of information. Manual card filing is made easier when the cards in the file as well as those to be filed are interpreted.
This is the first chapter on data processing machines which deals with wiring a control panel to direct machine operations. While the inter-preter is relatively Simple to wire and operate, a thorough understanding of the wiring
prin-ciples presented in this chapter will enable you to have a better understanding of the wiring principles involved for machines that are more complicated.
The operating principles of all popular types of interpreters are basically the same.
However, in order to acquaint you with their different characteristics each machine will be discussed separately.

INTERPRETER, TYPE 548
The type 548 interpreter, pictured in figure 6-1 is designed to translate numerical and alphabetic punched card data into printed charac-ters across the face of the card. Printing is performed by a set of 60 typebars, allowing for printing a maximum of 60 characters on one line in one pass of the cards through the machine.
Data can be printed on eit~er of two printing lines, called UPPER LINE and LOWER LINE.
A space or spaces may be left between different items of information. If all the data to be interpreted cannot be printed on one line, the remainder can be printed on a second line by rotating the printing poSition knob and passing the cards through the machine again. Flexibility of control panel wiring provides for printing the data in any sequence desired. Interpreting proceeds at the rate of 60 cards per minute.
OPERATING FEATURES Machine Controls
The MAIN LINE SWITCH supplies power to the machine, and must be ON for all machine operations. A green READY LIGHT goes on to indicate that the machine is readyforoperation.
The START KEY is depressed to start card feeding. It must be depressed and held until three cards have been fed inorder for continuous card feeding to be effective. The STOP KEY is depressed to stop card feeding.
Hopper
The card hopper holds approximately 700 cardso Cards must be placed in the hopper with the face up, and the 12 edge toward the throat of the hopper. When the last card leaves the hopper, it will be interpreted and stacked auto-maticallYG
