The IBM 402 series, introduced after World War II, had a similar print arrangement and was used by IBM in early computing devices, including the IBM Card-Programmed Electronic Calculator.

The IBM Card-Programmed Electronic Calculator or CPC was announced by IBM in May 1949.

Levy explains that MIT housed an early IBM 704 computer inside the Electronic Accounting Machinery ( EAM ) room in 1959.

The document says no, but quotes his son and then IBM President Thomas J. Watson, Jr., at the annual IBM stockholders meeting, April 28, 1953, as speaking about the IBM 701 Electronic Data Processing Machine, which it identifies as " the company's first production computer designed for scientific calculations ".

This display gave rise to several hobbyist and research wearables, including Gerald " Chip " Maguire's IBM / Columbia University Student Electronic Notebook, Doug Platt's Hip-PC and Carnegie Mellon University's VuMan 1 in 1991.

He left IBM in 1962 to found Electronic Data Systems ( EDS ) in Dallas, Texas, and courted large corporations for his data processing services.

The IBM 604 was a control panel programmable Electronic Calculating Punch introduced in 1948, and was a machine on which considerable expectations for the future of IBM were pinned and in which a corresponding amount of planning talent was invested.

It is based on Electronic Arts ' Interchange File Format, introduced in 1985 on the Amiga 1000, the only difference being that multi-byte integers are in little-endian format, native to the 80x86 processor series used in IBM PCs, rather than the big-endian format native to the 68k processor series used in Amiga and Apple Macintosh computers, where IFF files were heavily used.

Since the 1986 marriage of Burroughs and Sperry, Unisys has metamorphosed from a computer manufacturer to a computer services and outsourcing firm, competing in the same marketplace as IBM, Electronic Data Systems ( EDS ), and Computer Sciences Corporation.

IBM went on to build the Selective Sequence Electronic Calculator ( SSEC ) to both test new technology and provide more publicity for the company.

Known as the Defense Calculator while in development in the IBM Poughkeepsie Laboratory, this machine was formally unveiled April 7, 1953 as the IBM 701 Electronic Data Processing Machine.

is a skateboarding game released by Electronic Arts in 1988 for the Sinclair ZX Spectrum, Commodore 64, Atari ST, Apple IIgs, Amstrad CPC, and IBM Compatibles running MS-DOS.

In 1964, it was one of the few institutes with a computer, an IBM 1620 Model-II Electronic Computer.

* 1944 – IBM dedicates the first program-controlled calculator, the Automatic Sequence Controlled Calculator ( known best as the Harvard Mark I ).

Known officially as the Automatic Sequence Controlled Calculator, the Mark I was a general purpose electro-mechanical computer built with IBM financing and with assistance from IBM personnel, under the direction of Harvard mathematician Howard Aiken.

* August 7 – IBM dedicates the first program-controlled calculator, the Automatic Sequence Controlled Calculator ( known best as the Harvard Mark I ).

Proposals were requested from IBM and UNIVAC for this new system, to be called Livermore Automatic Reaction Calculator or LARC.

The IBM Automatic Sequence Controlled Calculator ( ASCC ), called the Mark I by Harvard University, was an electro-mechanical computer.

From the IBM Archives: The Automatic Sequence Controlled Calculator ( Harvard Mark I ) was the first operating machine that could execute long computations automatically.

The IBM 701, known as the Defense Calculator while in development, was announced to the public on April 29, 1952, and was IBM ’ s first commercial scientific computer.

The IBM Selective Sequence Electronic Calculator ( SSEC ) was an electromechanical computer built by IBM.

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.

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.
