Peripheral Devices
The basic 1130 came with an IBM 2310 voice-coil actuated disk drive, called "Ramkit", from IBM's General Products Division in San Jose. These read pizza-box-sized 2315 single platter cartridges that held 512 K words or 1 M byte (less than a 3.5" HD floppy). Disk memory was used to store the operating system, object code, and data; but source code was kept on punched cards.
The console typewriter used an IBM Selectric mechanism, which meant one could change the type by replacing a hollow, golf-ball sized type element. There was a special type element available for APL, a powerful array-oriented programming language using a special symbolic notation. A row of 16 toggle switches on the console typewriter could be individually tested from within programs, using the Fortran statement IF (SENSE SWITCH i), for example.
Other available peripherals included:
- Printers - the IBM 1132 and IBM 1403 lineprinters
- Punched-card - the IBM 1442 card reader/punch and the IBM 2501 card reader
- Paper tape - the IBM 1055 paper tape punch, the IBM 1054 paper tape reader, and the IBM 1134 paper tape reader
- Disk - the IBM 2311 Disk Drive
- Magnetic tape - From 1968, IBM 2415 Magnetic tape data storage drives were available as an RPQ.
- Graphics - IBM 2250 Graphic Display Unit and the IBM 1627 drum plotter.
- Communications - Synchronous Communications Adapter (SCA). The IBM 1130 MTCA, for Multiple Terminal Control Adapter, announced in 1970 allowed up to four 2741 terminals to be connected to an IBM 1130, for use with APL.

Famous quotes containing the words peripheral and/or devices:
“If we are to change our world view, images have to change. The artist now has a very important job to do. He’s not a little peripheral figure entertaining rich people, he’s really needed.”
—David Hockney (b. 1937)
“There is nothing in machinery, there is nothing in embankments and railways and iron bridges and engineering devices to oblige them to be ugly. Ugliness is the measure of imperfection.”
—H.G. (Herbert George)
