Apple Workgroup Server 60
The Macintosh Quadra 610, originally sold as the Macintosh Centris 610, is a personal computer designed, manufactured and sold by Apple Computer from February 1993 to July 1994. The Centris 610 was introduced alongside the larger Centris 650 as the replacement for the Macintosh IIsi, and it was intended as the start of the new midrange Centris line of computers. Later in 1993, Apple decided to follow an emerging industry trend of naming product families for their target customers Quadra for business, LC for education, and Performa for home and folded the Centris 610 into the Quadra family. The 610 is the second Macintosh case design (after the Macintosh LC family) to use a pizza box form factor; it was later used for the Quadra 660AV and the Power Macintosh 6100. A server variant, the Workgroup Server 60, was introduced in July 1993 with a 20 MHz processor, which received the same 25 MHz upgrade in October. In February 1994, a "DOS Compatible" version of the Quadra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Centris
Macintosh Centris is a family of personal computers designed, manufactured and sold by Apple Inc., Apple Computer, Inc. in 1992 and 1993. They were introduced as a replacement for the six-year-old Macintosh II family, Macintosh II family of computers; the name was chosen to indicate that the consumer was selecting a Macintosh in the ''center'' of Apple's product line. Centris machines were the first to offer Motorola 68040 CPUs at a price point around US$2,500, making them less expensive (albeit slower and less expansion options) than Macintosh Quadra, Quadra computers, but also offering considerably higher performance than the Macintosh LC family, Macintosh LC computers of the time powered by the Motorola 68030. Apple released three computers bearing the Centris name: the Macintosh Quadra 610, Centris 610 (replacing the Macintosh IIsi) and Macintosh Quadra 650, Centris 650 (replacing the Macintosh IIci in form and the Macintosh Quadra 700, Quadra 700 in function), both of which ...

Macworld
''Macworld'' is a digital magazine and website dedicated to products and software of Apple Inc., published by Foundry, a subsidiary of IDG. History ''Macworld'' was founded by David Bunnell and Cheryl Woodard (publishers) and Andrew Fluegelman (editor). It began as a print magazine in 1984, with its first issue distributed at the launch of the Macintosh computer. As a print magazine, it had the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, '' MacLife''. In 1997, the Ziff-Davis-owned '' MacUser'' magazine was consolidated into ''Macworld'' within the new Mac Publishing joint venture between IDG and Ziff-Davis. In 1999, the combined company also purchased the online publication MacCentral Online, because ''Macworld'' did not have a powerful online news component at the time. In late 2001 IDG bought out Ziff-Davis' share of Mac Publishing, making it a wholly-owned subsidiary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Desktops
Mac is a brand of personal computers designed and marketed by Apple Inc., Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to the McIntosh (apple), McIntosh apple. The current product lineup includes the MacBook Air and MacBook Pro laptops, and the iMac, Mac Mini, Mac Studio, and Mac Pro desktops. Macs are currently sold with Apple's UNIX-based macOS operating system, which is Proprietary software, not licensed to other manufacturers and exclusively Pre-installed software, bundled with Mac computers. This operating system replaced Apple's original Macintosh operating system, which has variously been named System, Mac OS, and Classic Mac OS. Jef Raskin conceived the Macintosh project in 1979, which was usurped and redefined by Apple co-founder Steve Jobs in 1981. The original Macintosh 128K, Macintosh was launched in January 1984, after Apple's 1984 (advertisement), "1984" advertisement during Super Bowl XVIII. A series of increment ...

AppleCD
AppleCD is a range of SCSI-based CD-ROM drives for Mac personal computers, manufactured and sold by Apple Computer from the late 1980s to late 1990s. Earlier AppleCD drives required a CD caddy in order to be used, while later models used a tray-loading mechanism. The original model introduced in 1988 was simply called the AppleCD SC. There was also a version of the CD drive that did not have the Apple logo. AppleCD SC The AppleCD SC was the first CD-ROM by Apple Computer Company, introduced in 1988. It originally contained a fan but in 1990 they removed it because it was unneeded and attracted dust onto the optical disk head which could cause problems. It uses a front-loading caddy 1x CD-ROM and is only capable of Read Only Media. This accessory device was only able to read compact discs up to a 650 MB capacity in five formats, CD-Audio, CD-ROM, HFS, ProDOS, and High Sierra. On the front of the device it has an eject button, mini-phono sound out jack, and a volume knob. On t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A/UX
A/UX is a Unix-based operating system from Apple Computer for Macintosh computers, integrated with System 7's graphical interface and application compatibility. It is Apple's first official Unix-based operating system, launched in 1988 and discontinued in 1995 with version 3.1.1. A/UX requires select 68k-based Macintosh models with an FPU and a paged memory management unit (PMMU). Its foundation is UNIX System V Release 2.2, with features from Releases 3 and 4 and from BSD versions 4.2 and 4.3. It is compliant with POSIX and System V Interface Definition (SVID), and includes TCP/IP networking since version 2. Having a Unix-compatible, POSIX-compliant operating system enabled Apple to bid for large contracts to supply computers to the U.S. federal government. A/UX was described by '' MacUser'' as "the most interesting and impressive software to have come out of Apple since HyperCard" and by ''InfoWorld'' as "an open systems solution with the Macintosh at its heart".

NuBus
NuBus () is a 32-bit parallel computer bus, originally developed at MIT during between 1978 and 1979 as part of the NuMachine workstation project, it would subsequently be standardized by the IEEE in 1987. The first complete implementation of the NuBus was done by Western Digital for their NuMachine, and for the Lisp Machines Inc. LMI Lambda. The NuBus was later incorporated in Lisp products by Texas Instruments (Explorer), and used as the main expansion bus by Apple Computer and a variant called NeXTBus was developed by NeXT. It is no longer widely used outside the embedded market. Architecture Early microcomputer buses like S-100 were often just connections to the pins of the microprocessor and to the power rails. This meant that a change in the computer's architecture generally led to a new bus as well. Looking to avoid such problems in the future, NuBus was designed to be independent of the processor, its general architecture and any details of its I/O handling. ...

AAUI
Apple Attachment Unit Interface (AAUI) is a mechanical re-design by Apple of the standard Attachment Unit Interface (AUI) used to connect computer equipment to Ethernet. The AUI was popular in the era before the dominance of 10BASE-T networking that started in the early 1990s; the AAUI was an attempt to make the connector much smaller and more user friendly, though the proprietary nature of the interface was also criticized. FriendlyNet AAUI is part of a system of Ethernet peripherals intended to make connecting over Ethernet easier. At the time of the introduction of AAUI, Ethernet systems usually were 10BASE2, also known as thinnet. Apple's system is called FriendlyNet. A FriendlyNet 10BASE2 system does not use BNC T-connectors or separate terminators. Instead of a single BNC connector that is inserted into a T-connector placed inline, the FriendlyNet transceiver has two BNC connectors, one on each side, to which the cables are attached. The transceiver automatically termi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Desktop Bus
Apple Desktop Bus (ADB) is a proprietary bit-serial peripheral bus connecting low-speed devices to computers. It was introduced on the Apple IIGS in 1986 as a way to support low-cost devices like keyboards and mice, enabling them to be connected together in a daisy chain without the need for hubs or other devices. Apple Desktop Bus was quickly introduced on later Macintosh models, on later models of NeXT computers, and saw some other third-party use as well. Like the similar PS/2 connector used in many PC-compatibles at the time, Apple Desktop Bus was rapidly replaced by USB as that system became popular in the late 1990s; the last external Apple Desktop Bus port on an Apple product was in 1999, though it remained as an internal-only bus on some Mac models into the 2000s. History AppleBus Early during the creation of the Macintosh computer, the engineering team had selected the fairly sophisticated Zilog 8530 to supply serial communications. This was initially done to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Processor Direct Slot
A processor direct slot (PDS) is a slot incorporated into many older Macintosh models that allowed direct access to the signal pins of a CPU, similar to the functionality of a local bus in PCs. This would result in much higher speeds than having to go through a bus layer, such as NuBus, which typically ran at a slower 10 MHz speed. Overview Typically, if a machine had bus expansion slots it would feature multiple bus expansions slots. However, there was never more than one PDS slot, as rather than providing a sophisticated communication protocol with ''arbitration'' between different bits of hardware that might be trying to use the communication channel at the same time, the PDS slot, for the most part, just gave direct access to signal pins on the CPU, making it closer in nature to a local bus. Thus, PDS slots tended to be CPU-specific, and therefore a card designed for the PDS slot in the Motorola 68030-based Macintosh SE/30, for example, would not work in the Moto ...

I486SX
The i486SX was a microprocessor originally released by Intel in 1991. It was a modified Intel i486, i486DX microprocessor with its Floating-point unit, floating-point unit (FPU) disabled. It was intended as a lower-cost CPU for use in low-end systems—selling for United States dollar, US$258—adapting the ''SX'' suffix of the earlier i386SX in order to connote a lower-cost option. However, unlike the i386SX, which had a 16-bit external data bus and a 24-bit external address bus (compared to the fully 32-bit i386DX, its higher-cost counterpoint), the i486SX was entirely 32-bit. The Intel486 SX-20 CPU can perform up 20 MIPS at 25 MHertz, Hz while this can also perform 70% faster than the 33 MHz Intel386 DX with external cache. Overview In the early 1990s, common applications, such as word processors and database applications, did not need or benefit from a floating-point unit, such as that included in the i486, introduced in 1989. Among the rare exceptions were Computer-aided desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
