As the speed of light in meters per second ( c < sub > 0 </ sub >) is fixed in the International System of Units, this measurement of the speed of light in AU / d ( c < sub > AU </ sub >) also determines the value of the astronomical unit in meters ( A ):

The remainder of day two included a two-second mid-course correction burn performed by the Command / Service Module's Service Propulsion System engine to tweak the spacecraft's trajectory.

While over the far side of the Moon, the Command / Service Module's Service Propulsion System engine burned for six minutes and fifteen seconds, braking the spacecraft into an orbit around the Moon with a low point ( pericynthion ) of 58. 3 and a high point ( apocynthion ) of 170. 4 nautical miles ( 108. 0 and 315. 6 km, respectively ).

* 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 ).

Originally released for the IBM 6150 RISC workstation, AIX now supports or has supported a wide variety of hardware platforms, including the IBM RS / 6000 series and later IBM POWER and PowerPC-based systems, IBM System i, System / 370 mainframes, PS / 2 personal computers, and the Apple Network Server.

Among other variants, IBM later produced AIX Version 3 ( also known as AIX / 6000 ), based on System V Release 3, for their IBM POWER-based RS / 6000 platform.

Since 1990, AIX has served as the primary operating system for the RS / 6000 series ( later renamed IBM eServer pSeries, then IBM System p, and now IBM Power Systems ).

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.

AIX / 370 was IBM's third attempt to offer Unix-like functionality for their mainframe line, specifically the System / 370 ( the prior versions were a TSS / 370 based Unix system developed jointly with AT & T c. 1980, and VM / IX a VM / 370 based system developed jointly with Interactive Systems Corporation c. 1984 ).

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

With the introduction of the ESA / 390 architecture, AIX / 370 was replaced by AIX / ESA in 1991, which was based on OSF / 1, and also ran on the System / 390 platform.

* 1964 – IBM announces the System / 360.

During the early 1960s, while also active in ASCII standardization, IBM simultaneously introduced in its product line of System / 360 the 8-bit Extended Binary Coded Decimal Interchange Code ( EBCDIC ), an expansion of their 6-bit binary-coded decimal ( BCDIC ) representation used in earlier card punches.

The prominence of the System / 360 led to the ubiquitous adoption of the 8-bit storage size, while in detail the EBCDIC and ASCII encoding schemes are different.

Gene Amdahl's seminal 1964 article on IBM System / 360 used 1K to mean 1024.

TWA canceled the project in 1970, acquiring one IBM System / 360 Model 75, two IBM System / 360 model 65s, and IBM's PARS software for its reservations system.

In 1964 IBM introduced its System / 360 computer architecture which was used in a series of computers that could run the same programs with different speed and performance.

The System / 360 architecture was so popular that it dominated the mainframe computer market for decades and left a legacy that is still continued by similar modern computers like the IBM zSeries.

The original System / 360 models of IBM mainframe had read-only control store, but later System / 360, System / 370 and successor models loaded part or all of their microprograms from floppy disks or other DASD into a writable control store consisting of ultra-high speed random-access read-write memory.

Examples of CISC instruction set architectures are System / 360 through z / Architecture, PDP-11, VAX, Motorola 68k, and x86.

Mature versions of the Commodore, SWTPC, Atari and Apple home computer systems all featured a disk operating system ( actually called ' DOS ' in the case of the Commodore 64 ( CBM DOS ), Atari 800 ( Atari DOS ), and Apple II machines ( Apple DOS )), as did ( at the other end of the hardware spectrum, and much earlier ) IBM's System / 360, 370 and ( later ) 390 series of mainframes ( e. g., DOS / 360: Disk Operating System / 360 and DOS / VSE: Disk Operating System / Virtual Storage Extended ).

Volume 1 ( ( Af ) of the seventh edition of Dana's System Of Mineralogy was published in 1944 and Volume 2 ( ( Af ) in 1951 by John Wiley & Sons, Inc., New York, N. Y..

This fiery swath was actually only a belt of minor planets, almost like the asteroid belt in the original Solar System.

These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids.

Just under five hours later, on the CSM's 65th orbit around the Moon, its Service Propulsion System main engine was reignited to propel the craft on a trajectory that would return it to Earth.

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

* A very High resolution monochrome video card with blitter and hardware text line and arc drawing capability, was designed for CAD applications, based on the NEC µPD7220 chip designed for graphic terminals, but was also used by some personal computers like the DEC Rainbow, and notably also for the Tulip System I.

In its prototype stage, the Atari 5200 was originally called the " Atari Video System X-Advanced Video Computer System ", and was codenamed " Pam " after a female employee at Atari Inc.

In January 1986, the 7800 was again released and would compete that year with the Nintendo Entertainment System and the Sega Master System.

Powering the system was an Atari SALLY 6502 ( Atari's slightly custom 6502, sometimes described as a " 6502C ") processor running at 1. 79 MHz, similar to the processor found in home computers ( Atari 8-bit, Apple II, Commodore 64 ) and other consoles ( Atari 5200 and Nintendo Entertainment System ).

Despite trailing the Nintendo Entertainment System in terms of number of units sold, the 7800 was a profitable enterprise for Atari Corp., benefiting largely from Atari ’ s name and the system's 2600 compatibility.

The most notable exception was the XG-1 lightgun, which came bundled with the Atari XE Game System.

Released on the XE Game System, an Atari 7800 version was started but not completed beyond a simple demo.

Atari Corp. then showed the Lynx to the press at the Summer 1989 CES as the " Portable Color Entertainment System ", which was changed to Lynx when actual consoles were distributed to resellers.

... was also a great and profound chess thinker second only to Steinitz, and his works – Die Blockade, My System and Chess Praxis – established his reputation as one of the father figures of modern chess.

In February 1997, with the legal right to the Coldcut name back, they released a double pack single " Atomic Moog 2000 " / " Boot the System ", the first Coldcut release on Ninja Tune.

System / 370 introduced virtual memory capabilities in all models other than the very first System / 370 models ; the OS / VS1 variant of OS / 360 MFT, the OS / VS2 ( SVS ) variant of OS / 360 MVT, and the DOS / VS variant of DOS / 360 were introduced to use the virtual memory capabilities, followed by MVS, which, unlike the earlier virtual-memory operating systems, ran separate programs in separate address spaces, rather than running all programs in a single virtual address space.

The MVS ( Multi Video System ), as the Neo Geo was known to the coin-operated arcade game industry, offered arcade operators the ability to put up to six different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace.

Nintendo Magazine System showed a preference for the multiplayer modes of the game and stated that while the " single player mode becomes dull quickly " the " two-player mode won't lose appeal ".

( The System / 370 series introduced a family of more powerful instructions such as the MVCL " Move-Characters-Long " instruction, which allows up to 16 MB to be moved as a single block.

In radio or wireless telephony, Private Line is a term trademarked by Motorola to describe their implementation of a Continuous Tone Coded Squelch System ( CTCSS ), a method of using low frequency subaudible tones to share a single radio channel among multiple users.

Modern geodetic reference systems, such as the World Geodetic System and the International Terrestrial Reference Frame, use a single Earth-centered oblate spheroid.

It also means that all parallel lines, be they millimetres apart or across the Solar System from each other, will seem to intersect the sphere at a single point, analogous to the vanishing point of graphical perspective.

DISA serves as the single senior manager for all Defense Information System Network ( DISN ) activities.

This contrasts with other file systems that store file and directory records in separate structures ( such as DOS's FAT file system or the Unix File System ), where having structure distributed across the disk means that damaging a single directory is generally non-fatal and the data may possibly be re-constructed with data held in the non-damaged portions.

** single action, producing sound only in one bellows direction ( usually found only on English System bass instruments and some baritone Instruments );

The primary concept of X. 500 is that there is a single Directory Information Tree ( DIT ), a hierarchical organization of entries which are distributed across one or more servers, called Directory System Agents ( DSA ).

By June 1989, an agreement was reached, and the only concession the RIAA would receive was a more practical recommendation from manufacturers to Congress that legislation be enacted to require that recorders have a Serial Copy Management System to prevent digital copying for more than a single generation.

However sometimes, usually in indoor competitions, the standard Yosemite Decimal System is substituted with a similar but more accurate system, in which the technical difficulty of the problem is measured by a single 3 or 4 digit number ( e. g., 810 or 1150 ).

Public education is provided by the Person County School System and administers a single unified school district with a K-12 program.

It had 128 KB of ROM on the motherboard, which was double the amount of ROM that was in previous Macs ; the new System software and ROMs included routines to support SCSI, the new 800 KB floppy drive, and the Hierarchical File System ( HFS ), which used a true directory structure on disks ( as opposed to the earlier MFS, Macintosh File System in which all files were stored in a single directory, with one level of pseudo-folders overlaid on them ).

Celtic music singer Loreena McKennitt, hard rock group Saving Abel, Christian rock groups Jars of Clay and dc Talk, R & B / Old school hip hop band Force MDs, R & B / electro-soul band The System, and jazz artist Grover Washington, Jr. are popular within their respective genres, but known to the greater public for a single song each.

The HOOPS 3D Graphics System appears to have been the first commercial scene graph library provided by a single software vendor.

Kishi is credited as being a key player in the initiation of the " 1955 System ", the extended period during which a single political party ( the LDP ) remained dominant.

Such a clock may be synchronized to the time sent by a single transmitter, such as many national or regional time transmitters, or may use multiple transmitters, like the Global Positioning System.

After technical negotiations, the two broadcasters settled in 1976 on a single standard, different from both Ceefax and Oracle, which ultimately developed into World System Teletext, and which in 2012 is still in use for analogue broadcasts.
