The analogue interface was normally used for joysticks, the parallel for a printer.

Per a News article on Page # 9 of the October 1984 issue of Acorn User, the Acorn ' Plus 2 ' interface was due to provide Econet capability.

Because the WD1770 is capable of single density mode and uses the same IBM360 derived floppy disc format as the Intel 8271 found in the BBC Micro, it was also possible to run a DFS filing system with an alternate ROM, such as the P. R. E. S AP4 interface.

The Plus 3 included an uprated Power-supply unit, that was designed to power the Plus 3, in addition to the Electron and the Plus 1 interface as well.

This was quickly remedied by First Byte Computers who developed an interface and software which allowed a " switched " joystick to be used with the majority of software titles.

This interface became very popular and was sold by W. H.

A third mode was entered with a special boot floppy which turned the Aster into a Videotex terminal with a 40x25 display and a Videotex character set, The software used the built in RS232 interface of the Aster to control a modem through which it could contact a Prestel service provider.

But these needed the infamous TRS-80 expansion interface, which was very expensive, and had a very unreliable floppy disk controller because it used the WD1771 floppy disc controller chip without an external " data separator ".

Still, the expansion interface was expensive and due to its design it was also unreliable.

After designing their own fully functional replacement for the TRS-80 expansion interface ( which was never commercialized ) the company realized that they could do better than just re-designing the expansion interface.

Because the original designer had left the company another employee completely redesigned most of the system, ( adding a display snow remover circuit, true 80 / 64 column text mode support, ( with different size letters for TRS-80 and CP / M mode, so that in TRS-80 mode the full screen was also used, not just a 64x16 portion of the 80x25 screen ) with an improved font set ( adding " gray scale " version of the TRS-80 mozaik graphics and many special PETSCII like characters ), and a more flexible and reliable floppy disk controller and keyboard interface plus many other small improvements ), also an enclosure was developed for the main computer system, ( in the form of a 19-inch rack for the Eurocards ) and for two floppy disk drives and the power supply.

A hard disk interface was also in the works, which would, add a SCSI interface, and the necessary software.

On the software front, work was being done to implement the replacement for the aging " user interface " of CP / M, ( the Command Console Processor CCP ) with the more modern ZCPR.

The Amiga Skyline BBS software was the first in 1987 featuring a script markup language communication protocol called Skypix which was capable to give the user a complete graphical interface, featuring rich graphic content, changeable fonts, mouse-controlled actions, animations and sound.

More recently, software with similar capabilities has been developed to allow manipulation of digital audio files stored on computers using turntables with special vinyl records ( e. g. Final Scratch, M-Audio Torq, Serato Scratch Live ) or computer interface ( e. g. Traktor DJ Studio, Mixxx, Virtual DJ ).

If this special relationship does not exist then it not usually spoken of as " backward " compatibility but is instead just " compatible "— a consistent interface allowing interoperability between components and products that were each developed separately.

The command interface developed into a compiled structured language with declarations, statements and procedures called WFL ( Work Flow Language ).

It wasn't until 1902 that the familiar push-button user interface was developed, with the introduction of the Dalton Adding Machine, developed by James L. Dalton in the United States.

He and his team developed computer interface elements such as bitmapped screens, the mouse, hypertext, collaborative tools, and precursors to the graphical user interface.

He conceived and developed many of his user interface ideas back in the mid-1960s, long before the personal computer revolution, at a time when most individuals were kept away from computers, and could only use computers through intermediaries ( see batch processing ), and when software tended to be written for vertical applications in proprietary systems.

The PRISM's Epicode was developed into the Alpha's PALcode, providing an abstracted interface to platform-and processor implementation-specific features.

Therefore, the ISA bus was synchronous with the CPU clock, until sophisticated buffering methods were developed and implemented by chipsets to interface ISA to much faster CPUs.

CDE was an X11-based user environment jointly developed by HP, IBM, and Sun through the X / Open consortium, with an interface and productivity tools based on the Motif graphical widget toolkit.

Mesa was developed on the Xerox Alto, one of the first personal computers with a graphical user interface, however most of the Alto's system software was written in BCPL.

Three-tier is a client – server architecture in which the user interface, functional process logic (" business rules "), computer data storage and data access are developed and maintained as independent modules, most often on separate platforms.

* Mission Data Interface, an interface developed by NUWC Keyport

This fate was averted when Wayne Davison developed trn, a set of patches to rn which gave it both threading at the article level and a new user interface that would allow users to select only the threads they desired, while remaining true to the original rn interface philosophy of do the right thing.

* Asymmetrical definitions of the two ends of the link make the assignment of the role of a newly developed device problematic ; the designer must decide on either a DTE-like or DCE-like interface and which connector pin assignments to use.

… that all such systems developed for use by U. S. forces are considered to be for joint use .” To achieve this the director of the Defense Information Systems Agency ( DISA ) is charged with “ developing information technology standards to achieve interoperability and compatibility … ensure that all systems and equipment shall conform to technical and procedural standards for interface, interoperability, and compatibility ”.

As it was easy to get hardware specifications, numerous bespoke devices were developed by small companies such as A / D converters and even an interface to the entire range of Mitutoya measuring equipment, allowing it to be used in quality control for various car manufacturers.

Later in the 1960s, Sylvania's Electronic Systems Division in Needham, MA developed and manufactured several instruments for the Apollo Lunar Lander and Command Module using electroluminescent display panels manufactured by the Electronic Tube Division of Sylvania at Emporium, PA. Raytheon, Sudbury, MA, manufactured the Apollo guidance computer, which used a Sylvania electroluminescent display panel as part of its display-keyboard interface ( DSKY ).

The pictures of Figs. 3 and 4 show the cracking and peeling types of removal where the coating is detached by failure in a region at, or close to, the interface between coating and substrate.

The various services all took on a common interface device, an " i-bar " branded with the BBCi logo, which sought to emphasise the brand across different technologies by providing similar navigation.

Thus, a PICMG backplane can provide any number and any mix of ISA, PCI, PCI-X, and PCI-e slots, limited only by the ability of the SBC to interface to and drive those slots.

MMORPGs are described by some players as " chat rooms with a graphical interface ".

In a p-channel depletion-mode device, a positive voltage from gate to body creates a depletion layer by forcing the positively charged holes away from the gate-insulator / semiconductor interface, leaving exposed a carrier-free region of immobile, negatively charged acceptor ions.

Developers create applications that duplicate and extend the interface that was introduced by PathMinder and John Socha's famous Norton Commander for DOS.

The concept of hyperlinks was further refined and extended to graphics by researchers at Xerox PARC, specifically Alan Kay, who went beyond text-based hyperlinks and used a GUI as the primary interface for the Xerox Alto computer.
