Some third party hard disks for IBM PCs were sold as kits including a controller card and replacement power supply, and some were integrated with their controller into a single expansion card, commonly called a " Hard Card ".

To recognize increased scope beyond memory, and to aid in marketing, the association acquired the rights to the simpler term " PC Card " from IBM.

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.

When the LOAD button on the IBM 1402 Card Read-Punch was pressed, a card was read into memory locations 001-080, a word mark was set in location 001, the word marks in locations 002-080 were cleared, and execution started with the instruction at location 001.

It ran on IBM mainframe computers using the Michigan Terminal System.

Terminal transmission control protocols such as IBM 3270 Poll / Select, or Burroughs TD830 Contention Mode protocol use the EOT character to terminate a communications sequence between two cooperating stations ( such as a host multiplexer or Input / Output terminal ).

Several operating systems for the IBM S / 360 and S / 370 architectures were developed by third parties, including the Michigan Terminal System ( MTS ) and MUSIC / SP.

# MAD / I, an " extended " version of MAD for the IBM S / 360 series of computers running under the Michigan Terminal System ( MTS ).

# GOM ( Good Old MAD ), a reimplementation of the original 7090 MAD for the IBM S / 370 series of mainframe computers running the Michigan Terminal System ( MTS ).

LPT ( Line Print Terminal or Local Print Terminal ) is the original, and still common, name of the parallel port interface on IBM PC-compatible computers.

It made the 5100 appear the same as an IBM 2741 Communications Terminal and was designed to be able to communicate with IBM 2741 compatible machines in start-stop mode using the EBCD ( Extended Binary Coded Decimal ) notation.

The 1711 contained an analog-to-digital converter that accepted signals from the IBM 1712 Multiplexer and Terminal Unit that were between-50 millivolts and + 50 millivolts and converted them into signed, four decimal digit numbers that were stored in the 1710s core memory.

The IBM 1712 Multiplexer and Terminal Unit was part of the IBM 1710 process control computer.

IBM 3486 Terminal, a later terminal with 5250 functionality, capable of supporting two independent sessions concurrently, and with an amber screen.

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.
