Apple Workgroup Server
Apple Workgroup Server and Macintosh Server are a family of Macintosh-based workgroup servers, sold by Apple Computer from 1993 to 2003. Machines bearing these names are re-branded Centris, Quadra and Power Macintosh systems with additional server software and sometimes larger hard drives. Apart from that, they were mostly identical to the machines they are based on. The "Workgroup Server" name was used until the release of the Power Macintosh G3 in 1998. In 1996 and 1997, Apple also sold a separate range of machines marketed as the Apple Network Server, which were specially-designed servers that exclusively ran AIX and thus do not qualify as Macintosh computers. The first models were the Workgroup Server 60, 80 and 95, introduced together at CeBIT in Hanover on March 22, 1993. Customer shipments of the 95 began in April, with the 60 and 80 following in July. New models were introduced every year except 1995, and remained on the market until 2003, several months after the rack-m ...

PowerPC 601
The PowerPC 600 family was the first family of PowerPC processors built. They were designed at the Somerset facility in Austin, Texas, jointly funded and staffed by engineers from IBM and Motorola as a part of the AIM alliance. Somerset was opened in 1992 and its goal was to make the first PowerPC processor and then keep designing general purpose PowerPC processors for personal computers. The first incarnation became the PowerPC 601 in 1993, and the second generation soon followed with the PowerPC 603, PowerPC 604 and the 64-bit PowerPC 620. Nuclear family PowerPC 601 The PowerPC 601 was the first generation of microprocessors to support the basic 32-bit PowerPC instruction set. The design effort started in earnest in mid-1991 and the first prototype chips were available in October 1992. The first 601 processors were introduced in an IBM RS/6000 workstation in October 1993 (alongside its more powerful multichip cousin IBM POWER2 line of processors) and the first Apple Pow ...

System 7
System 7, codenamed "Big Bang", and also known as Mac OS 7, is a graphical user interface-based operating system for Macintosh computers and is part of the classic Mac OS series of operating systems. It was introduced on May 13, 1991, by Apple Computer It succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. Current for more than six years, System 7 was the longest-lived major version series of the classic Macintosh operating system (to date, only Mac OS X had a longer lifespan). Features added with the System 7 release included virtual memory, personal file sharing, QuickTime, QuickDraw 3D, and an improved user interface. With the release of version 7.6 in 1997, Apple officially renamed the operating system "Mac OS", a name that had first appeared on System 7.5.1's boot screen. System 7 was developed for Macs that used the Motorola 680x0 line of processors, but was ported to the PowerPC after Apple adopted the new processo ...

Mac OS 9
Mac OS 9 is the ninth major release of Apple's classic Mac OS operating system which was succeeded by Mac OS X (renamed to OS X in 2011 and macOS in 2016) in 2001. Introduced on October 23, 1999, it was promoted by Apple as "The Best Internet Operating System Ever", highlighting Sherlock 2's Internet search capabilities, integration with Apple's free online services known as iTools and improved Open Transport networking. While Mac OS 9 lacks protected memory and full pre-emptive multitasking, lasting improvements include the introduction of an automated Software Update engine and support for multiple users. Apple discontinued development of Mac OS 9 in late 2001, transitioning all future development to Mac OS X. The final updates to Mac OS 9 addressed compatibility issues with Mac OS X while running in the Classic Environment and compatibility with Carbon applications. At the 2002 Worldwide Developers Conference, Steve Jobs began his keynote address by staging a mock f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megabyte
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix ''mega'' is a multiplier of (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. In the computer and information technology fields, other definitions have been used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as (220 B), a quantity that conveniently expresses the binary architecture of digital computer memory. The standards bodies have deprecated this usage of the megabyte in favor of a new set of binary prefixes, in which this quantity is designated by the unit mebibyte (MiB). Definitions The unit megabyte is commonly used for 10002 (one million) bytes or 10242 bytes. The interpretation of using base 1024 originated as technical jargon for the byte multiples that ...

Macintosh Quadra 950
The Macintosh Quadra 950 (also sold with additional software as the Workgroup Server 95) is a personal computer designed, manufactured and sold by Apple Computer from March 1992 to October 1995. It replaced the Quadra 900 that was introduced several months earlier, increasing the CPU clock rate of its 68040 CPU from to , and improving the graphics support. The two computers were otherwise identical, including the price. With a Macintosh Processor Upgrade Card installed, this computer is known as the Power Macintosh 950. In 1993, the 950 was overtaken in performance by the less expensive Quadra 800 and 840AV. The newer Quadras had the addition of interleaved RAM, as well as an enhanced video system and SCSI bus. However, their more compact (mini-tower) case offered less expansion capability, so the 950 (due to its mid-tower case allowing 6 slots to be supported) was kept in continued production for the server market, outliving the 800 and 840AV. Also, the Quadra 800 was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macintosh Quadra 900
The Macintosh Quadra 900 is a personal computer designed, manufactured, and sold by Apple Computer from October 1991 to May 1992. It was introduced alongside the Quadra 700 as the first computers in the Macintosh Quadra, Quadra family of Macintosh computers using the Motorola 68040 processor. It is also the first computer from Apple to be housed in an 18.6 inch (47 cm) tall Computer tower#Mid-tower, mid-tower form factor, which by 1991 had gained momentum with PC manufacturers as a suitable design for departmental servers. The Quadra 900 had a short lifespan; it was discontinued about six months after the first shipments in favor of the more powerful Macintosh Quadra 950, Quadra 950. Hardware The Quadra 900 was more expandable than the Quadra 700 but cost US$7,200. The Quadra 900 could be upgraded to 256 megabytes of RAM, an astronomical amount for the time, when a typical midrange system would come equipped with 2–4 MB.

Tape Backup
A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and a long archival stability. A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data. As a result, tape drives have very large average access times. However, tape drives can stream data very quickly off a tape when the required position has been reached. For example, Linear Tape-Open (LTO) supports continuous data transfer rates of up to 360 MB/s, a rate comparable to hard disk drives. Design Magnetic tape drives with capacities of less than one megabyte were first used for data storage on mainframe computers in the 1950s. , capacitie ...

Power Macintosh
The Power Macintosh, later Power Mac, is a family of personal computers designed, manufactured, and sold by Apple Computer as the core of the Macintosh brand from March 1994 until August 2006. Described by ''MacWorld'' as "the most important technical evolution of the Macintosh since the Macintosh II, Mac II debuted in 1987", it is the first computer with the PowerPC CPU architecture, the flagship product of the AIM alliance. Existing software for the Motorola 68040, Motorola 68k processors of previous Macintoshes do not run on it natively, so a Mac 68k emulator is in System 7.1.2. It provides good compatibility, at about two thirds of the speed of contemporary Macintosh Quadra machines. The Power Macintosh replaced the Quadra, and was initially sold in the same enclosures. Over the next twelve years, it evolved through a succession of enclosure designs, a rename to "Power Mac", five major generations of PowerPC chips, and a great deal of press coverage, design accolades, and co ...
