Later, 407 print mechanisms were used in the IBM 1132 line printer, part of the low cost IBM 1130 computer system.

The 1132 was built around a stripped down IBM 407 printing mechanism.

Another example of one of these is the IBM 6400 Line Matrix Printer that uses continuous forms.

Printer steganography is a type of steganography produced by color printers, including Brother, Canon, Dell, Epson, HP, IBM, Konica Minolta, Kyocera, Lanier, Lexmark, Ricoh, Toshiba and Xerox brand color laser printers, where tiny yellow dots are added to each page.

The other nine units in ENIAC were the Initiating Unit ( which started and stopped the machine ), the Cycling Unit ( used for synchronizing the other units ), the Master Programmer ( which controlled " loop " sequencing ), the Reader ( which controlled an IBM punched card reader ), the Printer ( which controlled an IBM punched card punch ), the Constant Transmitter, and three Function Tables.

It was the 1401 that transferred input data from peripherals, such as the IBM 1402 Card Read-Punch, to tape, and transferred output data from tape to the card punch, the IBM 1403 Printer, or other peripherals.

Primary user input was decimal, via standard IBM 80 column punched cards and output was decimal, via a front panel display.

It was also a less expensive alternative to the Apple Macintosh and IBM PC as a general-purpose business or home computer.

* Attached Support Processor, one of the two early IBM System / 360 programs that replaces the native SPOOL facilities of OS / 360 ; the other was Houston Automatic Spooling Priority ( HASP ).

AIX was the first operating system to utilize journaling file systems, and IBM has continuously enhanced the software with features like processor, disk and network virtualization, dynamic hardware resource allocation ( including fractional processor units ), and reliability engineering ported from its mainframe designs.

AIX Version 1, introduced in 1986 for the IBM 6150 RT workstation, was based on UNIX System V Releases 1 and 2.

A beta test version of AIX 5L for IA-64 systems was released, but according to documents released in the SCO v. IBM lawsuit, less than forty licenses for the finished Monterey Unix were ever sold before the project was terminated in 2002.

IBM maintains that their license was irrevocable, and continued to sell and support the product until the litigation was adjudicated.

AIX was a component of the 2003 SCO v. IBM lawsuit, in which the SCO Group filed a lawsuit against IBM, alleging IBM contributed SCO's intellectual property to the Linux codebase.

The original AIX ( sometimes called AIX / RT ) was developed for the IBM 6150 RT workstation by IBM in conjunction with Interactive Systems Corporation, who had previously ported UNIX System III to the IBM PC for IBM as PC / IX.

This was based on a design pioneered at IBM Research ( the IBM 801 ).

AIX PS / 2 ( also known as AIX / 386 ) was developed by Locus Computing Corporation under contract to IBM.

AIX / 370 was released in 1990 with functional equivalence to System V Release 2 and 4. 3BSD as well as IBM enhancements.

This development effort was made partly to allow IBM to compete with Amdahl UTS.

As an example, if one was trying to profit from a price discrepancy between IBM on the NYSE and IBM on the London Stock Exchange, they may purchase a large number of shares on the NYSE and find that they cannot simultaneously sell on the LSE.

The encoding of data by discrete bits was used in the punched cards invented by Basile Bouchon and Jean-Baptiste Falcon ( 1732 ), developed by Joseph Marie Jacquard ( 1804 ), and later adopted by Semen Korsakov, Charles Babbage, Hermann Hollerith, and early computer manufacturers like IBM.

Contrasting with at-the-time normal industry practice, IBM created an entire series of computers ( or CPUs ) from small to large, low to high performance, all using the same instruction set ( with two exceptions for specific markets ).

In 2007, a team from the IBM Almaden Research Center and the University of Nevada ran an artificial neural network almost half as complex as the brain of a mouse for the equivalent of a second ( the network was run at 1 / 10 of normal speed for 10 seconds ).

IBM designed IBM i as a " turnkey " operating system, requiring little or no on-site attention from IT staff during normal operation.

CTSS used a modified IBM 7094 mainframe computer that had two 32, 768 36-bit word banks of core memory instead of the normal one ; users had access to 27K of the total 32K, with the remaining 5K reserved for the monitor.

Examples include the floppy disk controller on the Amstrad PCW, the 8087 coprocessor on the x86 when used in the IBM PC or its compatibles ( even though Intel recommended connecting it to a normal interrupt, causing the error pin on the 287 when used in the IBM PC / AT to be connected to a normal interrupt rather than directly to the 286 error pin, for which the handler jumps to the NMI handler, and later causing Intel, in the 486, to add the MS-DOS compatibility mode to it ), and the Low Battery signal on the HP 95LX.

An item-marked op-code would be handled differently from normal, and this was used in the emulation of IBM 1401 instructions that were not directly compatible.
