Includes a 120-character buffer.
The 60-word (120-character) output records are transferred to the 1403 buffer on a cycle-stealing basis. Characters are translated to print chain character number under program control.
Model 6 prints 340 or 210 lines per minute, and Model 7 prints 600 lines per minute with the standard 48-character type font.
Standard 48-character type font includes 12 special characters (FORTRAN).
Character spacing, 10 per inch.
Manual selection of line spacing, 6 or 8 lines per inch.
Forms skipping at 33 inches per second.
Type arrangement HN is standard.
Optional — Interchangeable Chain Cartridge Adapter for additional alphameric arrangements.
Auxiliary Ribbon Feed Feature.

Reads 8-channel punched paper tape directly into the 1131 processor at 60 characters per second.
Translation of punched image into any code by stored program.
Control of reading through automatic interrupt system—allowing overlap with other I/O operations.
Optional reels, supply and takeup, for feeding and reading punched tape in roll form.
Capability for automatic program loading operations in paper-tape-only system configurations through the Paper Tape Reader Loader feature.
Direct connection to 1131 Processor by means of 1134 Paper Tape Reader Adapter.

Direct punched paper tape output from the 1131 processor at 14.8 characters per second.
Capability for punching output data in any code format through program control.
Control of punching by means of the automatic interrupt system, allowing overlap with other I/O operations.
Optional takeup reel for automatically winding output tape into roll form.
Connection with 1131 Processor through 1055 Paper Tape Punch Adapter.

Serial card feeding for flexible I/O operations. Model 6 reads 300 cards per minute and punches 80 columns per second maximum. Model 7 reads 400 cards per minute and punches 160 columns per second maximum.
Independent control of each function by stored program.
Automatic checking of reading and punching.
Large-capacity hopper for continuously feeding 1200 cards.
Two radial, nonstop stackers with capacity for 1300 cards each.
Stored-program-controlled stacker selection.
Binary image of cards is read or punched in 12-bit column image format.
Translation of column image to or from any code by stored program.
Control of reading and punching operations through 1131 Central Processing Unit automatic interrupt system.
Direct connection to 1131 Central Processing Unit through 1442 Attachment.

Operates serially at 160 columns per second, allowing punching speeds up to 90 cards per minute.
Provides separate path for punching to allow overlapping punching with reading.
Automatic checking of punching.
Large-capacity hopper for continuously feeding 1200 cards.
Two radial, nonstop stackers with capacity for 1300 cards each.
Stored-program-controlled stacker selection.
Binary image of cards is punched in 12-bit column image format.

Model A1 reads 600 cards per minute.
Model A2 reads 1000 cards per minute.
Provides separate high-speed card input for improved throughput performance.
Standard 1200-card-capacity hopper and 1300-card-capacity stacker.
Operates on a cycle-stealing basis, with one core storage cycle per card column.

Optically reads standard #2 pencil marks on a source document, and transfers information directly to 1131 Central Processing Unit.
Can maintain a document throughput of 2000 per hour.
Once source documents are placed in hopper, the 1231, under stored program control, requires no further operator intervention.
In a single pass through the reader, marks are read and checked, and information is transferred to the processor on a fully buffered interrupt basis.
Master mark data is transferred to the 1131 only during reading of the master mark sheet.
Source documents measure 8-1/2" by 11", with up to 1000 marking positions.
Mark discrimination compares marks against a predetermined level. Data sheets can be rejected under program control if a weak or invalid mark is detected.
Cannot be attached to system using a 2501 Card Reader.

Efficient typewheel printing concept.
Standard 48-character-set typewheels include FORTRAN special character set.
High-speed online printing.
Model 1 prints up to 80 alphameric or 110 numeric lines per minute and can be attached to 1131 CPU Models 1, 2, 3, and 5.
Model 2 prints up to 40 alphameric or 55 numeric lines per minute and may be attached only to the 1131 CPU Model 4.
Standard 120 print-line positions spaced 10 characters per inch.
Operator selection of vertical line spacing, 6 or 8 lines per inch.
Forms skipping under program control through automatic, paper-tape-controlled carriage.
Printer operation under stored-program control through automatic interrupt system.
Direct connection to the 1131 Central Processing Unit by means of the 1132 Printer Attachment and an Expansion Adapter.

Model 1: Three hundred 1/100" increments per second and 12"-wide chart allow plots on 11" Y axis and up to 120-foot X axis.
Model 2: Two hundred 1/100" increments per second and a 30"-wide chart allow plots on 29-1/2" Y axis and up to 120-foot X axis.
Provides online, plotted graphic output for 1130 Computing Systems.
Plotting in single-increment character mode overlapped with computing by means of the 1131 processor automatic interrupt system.
Ball-point pens standard, with liquid-ink pens available in two models.
Pen-up and pen-down commands allow up to 10 pen status changes per second.
Receives direct numerical data from the 1131 Central Processing Unit for +X, -X, +Y, -Y, +Z, or -Z plot movement.
Communication with 1627 Plotter from the 1131 Central Processing Unit under control of the automatic interrupt system.
Circuitry and controls interface for attachment to 1130 Computing System through the 1627 Plotter Attachment.
Other plotters available on request.

Provides graphic capability useful in such fields as engineering design and analysis, either as a stand-alone system, or as a graphic access device to the more powerful IBM System/360.
The Model 4 can present alphameric and line drawing information on a cathode ray tube.
Alphameric character fonts are programmable, and may include upper and lower case as well as superscripting and subscripting.
Equipped with fiber optic light pen and optional alphameric and program function keyboards.
Designed for simultaneous operation with the CPU or other I/O device in a cycle-stealing mode.

A Synchronous Communication Adapter permits the 1130 to function as a point-to-point processor terminal at speeds of 600, 1200, 2000, 2400 or 4800 bits per second in Binary Synchronous mode.
Operation is in priority level interrupt mode to permit overlapped operation with other I/O devices.
Data is transmitted or received in half-duplex mode over 2- or 4-wire communication facilities.
Code-insensitive transmission.
Line control, data transfer, and code conversion are under program control.
Auto-answer and audible alarm for operator attention are provided. Can transmit scientific and commercial data.
