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.

A similar solution was the 850 kbit / s DaynaTalk, a separate box which plugged in between the computer and a normal LocalTalk / PhoneNet box, and also offered as a PC expansion card that ran up to 1. 7 Mbit / s.

These included updates to EtherTalk and TokenTalk, AppleTalk software and LocalTalk hardware for the IBM PC, EtherTalk for Apple's A / UX operating system allowing it to use LaserPrinters and other network resources, and the Mac X. 25 and MacX products.

This signal would be fed into the sound card audio input of the PC, and Banpaia would decode the ESN / MIN pair from this signal and display it on the screen.

This drive was one of several types installed into the IBM PC / XT and extensively advertised and reported as a " 10 MB " ( formatted ) hard disk drive.

In IBM PC compatible computers, the Basic Input / Output System ( BIOS ), also known as the system BIOS or ROM BIOS (), is a de facto standard defining a firmware interface.

The BIOS then locates boot loader software held on a peripheral device ( designated as a ' boot device '), such as a hard disk or a CD / DVD, and loads and executes that software, giving it control of the PC.

* IBM PC CP / M-86

Before going further with serious experimentation, it can be convenient to check one ’ s programs at the PC using a suitable cross-assembler, such as the portable PDP-8 / DG Nova cross-assembler listed in the External links section, before attempting execution in the RDOS environment.

The shopping service at launch featured WH Smith, Tesco, Virgin / Our Price, Great Universal Stores / GUS, Interflora, Dixons Retail, Past Times, PC World ( retailer ) and Innovations.

It was announced in September 1988 by a consortium of PC clone vendors ( the " Gang of Nine ") as a counter to IBM's use of its proprietary Micro Channel architecture ( MCA ) in its PS / 2 series.

EISA extends the AT bus, which the Gang of Nine retroactively renamed to the ISA bus to avoid infringing IBM's trademark on its PC / AT computer, to 32 bits and allows more than one CPU to share the bus.

The PC / AT, introduced in 1984, had three 8-bit slots and five 16-bit slots, all running at the system clock speed of 6 MHz in the earlier models and 8 MHz in the last version of the computer.

Although his career in computing spanned more than two decades, he is mainly remembered in connection with IBM's unsuccessful attempt in 1980 to license CP / M for the IBM PC.

IBM approached Digital Research in 1980, at Bill Gates ' suggestion, to negotiate the purchase of a forthcoming version of CP / M called CP / M-86 for the IBM PC.

The IBM PC / XT in 1983 included an internal 10MB hard disk drive, and soon thereafter internal hard disk drives proliferated on personal computers.

IBM designed the 8-bit version as a buffered interface to the external bus of the Intel 8088 ( 16 / 8 bit ) CPU used in the original IBM PC and PC / XT, and the 16-bit version as an upgrade for the external bus of the Intel 80286 CPU used in the IBM AT.

Later models followed in the trend: for example, the PC / XT, IBM Portable Personal Computer, and PC AT are IBM machine types 5160, 5155, and 5170, respectively.

The first IBM PC model with an internal non-removable hard disk was IBM's model 5160, the XT.

* March 8 – IBM releases the IBM PC XT.

Replacement of the factory-installed 8250 UART was a common upgrade for owners of IBM PC, XT, and compatible computers when high-speed modems became available.

The IBM PC, XT, and most compatibles based on the 8088 or 8086 had a socket for the optional 8087 coprocessor.

This is in addition to the hardware standard on the IBM PC, PC / XT, and PC / AT motherboards: keyboard interface, expansion slots, memory subsystem, DMA, interrupt controller, and math coprocessor socket.

) An IBM PC, XT or AT would require at least 4 expansion cards for similar hardware: one video graphics adapter card, one floppy disk controller ( FDC ) card, one serial and parallel port card, and one sound card with a joystick port.

( 4. 77 MHz was the speed of the 8088 in the IBM PC and PC / XT models and so was the de-facto standard speed for an 8088 in an IBM-compatible.

( Earlier Tandy 1000 models, like IBM PC and PC / XT systems, used DIP switches for startup configuration settings.

* IBM PC compatible, computers that are generally similar to the original IBM PC, XT, and AT

IBM PC compatible computers are those generally similar to the original IBM PC, XT, and AT.

* The availability by 1986 of sub -$ 1000 PC XT compatibles, including early offerings from Dell Computer, reducing demand for IBM's models.

( Contrast this with all of the " family one " IBM PC desktop models — the PC, PC / XT, and PC AT — which required a display adapter installed in a slot in order to connect a monitor.

Backplanes have grown in complexity from the simple Industry Standard Architecture ( ISA ) ( used in the original IBM PC ) or S-100 style where all the connectors were connected to a common bus.

PC Floppy controllers ( ISA or onboard, but not USB floppy drives ) are able to deal with the 1581 format without need for any special tricks.

Industry Standard Architecture ( ISA ) is a computer bus standard for IBM PC compatible computers introduced with the IBM Personal Computer to support its Intel 8088 microprocessor's 8-bit external data bus and extended to 16 bits for the IBM Personal Computer / AT's Intel 80286 processor.

The ISA bus was developed by a team led by Mark Dean at IBM as part of the IBM PC project in 1981.

In 1988, the Gang of Nine IBM PC compatible manufacturers put forth the 32-bit EISA standard and in the process retroactively renamed the AT bus to " ISA " to avoid infringing IBM's trademark on its PC / AT computer.

The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of ISA plus one VESA Local Bus as the bus configuration.

In the early 1990s the I / O bandwidth of the ISA bus was becoming a critical bottleneck to PC graphics performance.

In the original IBM PC, there was only one Intel 8237 DMA controller capable of providing four DMA channels ( numbered 0-3 ), as part of the so-called Industry Standard Architecture, or ISA.

The only pieces of legacy hardware that use ISA DMA and are still fairly common are the built-in Floppy disk controllers of many PC mainboards and those IEEE 1284 parallel ports that support the fast ECP mode.

Adapters for PC Cards to Personal Computer ISA slots were available when these technologies were current.

Installing a timer interrupt handler allows a TSR to run periodically ( see ISA and programmable interval timer, especially the section " IBM PC compatible ").

IBM introduced the Industry Standard Architecture ( ISA ) bus, with the IBM PC in 1981 ; it was then called the PC bus.

EISA, the 32-bit extended version of ISA championed by Compaq, was used on some PC motherboards until 1997, when Microsoft declared it a " legacy " subsystem in the PC 97 industry white-paper.

The PC / 104 bus is an embedded bus that copies the ISA bus.

The PC clone market did not want to pay royalties to IBM in order to use this new technology, and for desktop machines vendors of PC-compatibles stayed largely with the 16-bit AT bus, ( embraced and renamed as ISA to avoid IBM's " AT " trademark ) and manual configuration, although the VESA Local Bus was briefly popular for Intel ' 486 machines.

Most Atari ST ( Mega STE model ), and Atari TT framebuffers were created for the VME rear connector slot of Atari machines dedicated to video expansion cards: Leonardo 24-bit VME graphics adapter, CrazyDots II 24-bit VME graphics card, Spektrum TC graphics card, NOVA ET4000 VME SVGA graphics card ( capable of resolutions up to 1024x768 at 256 colors or 800x600 at 32768 colors ), whose design came from the ISA / PC world ( it was effectively an ATI Mach32 S: with 1 MB of video RAM ).

The popularity of IBM's first personal computers made the ISA bus, first used on the IBM PC in 1981 and later extended to 16-bit in 1984 with the IBM PC / AT, the undisputed standard expansion bus for personal computers shortly after.

EGA cards use the PC ISA bus and were available starting in 8-bit versions.

A network interface card ( NIC ) was developed for the IBM PC industry standard architecture ( ISA ) bus.
