Macintosh Quadra 610
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 Centris / Quadra 660AV and the Power Macintosh 6100. The Quadra 610 was also sold in a "DOS compatible" model with an additional 486SX processor at 25 MHz on a Processor Direct Slot card. A server variant, the Workgroup Server 60, was introduced in July ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Quadra
The Macintosh Quadra is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. from October 1991 to October 1995. The Quadra, named for the Motorola 68040 central processing unit, replaced the Macintosh II family as the high-end Macintosh model. The first models were the Quadra 700 and Quadra 900, both introduced in October 1991. The Quadra 800, 840AV and 605 were added through 1993. The Macintosh Centris line was merged with the Quadra in October 1993, adding the 610, 650 and 660AV to the range. After the introduction of the Power Macintosh line in early 1994, Apple continued to produce and sell new Quadra models; the 950 continued to be sold until October, 1995. The product manager for the Quadra family was Frank Casanova who was also the Product Manager for the Macintosh IIfx. Models The first computers bearing the Macintosh Quadra name were the Quadra 700 and Quadra 900, both introduced in 1991 with a central processing unit (CPU) s ...

Macintosh Centris
Macintosh Centris is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. in 1992 and 1993. They were introduced as a replacement for the six-year-old 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 significantly less expensive (albeit slower) than Quadra computers, but also offering higher performance than the Macintosh LC computers of the time. Apple released three computers bearing the Centris name: the Centris 610 (replacing the Macintosh IIsi) and Centris 650 (replacing the Macintosh IIci in form and the Quadra 700 in function), both of which were introduced in March 1993, and the Centris 660AV which followed in July. Apple also considered the Macintosh IIvx to be part of the Centris line. The IIvx was released in October of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Desktops
The Mac (known as Macintosh until 1999) is a family of personal computers designed and marketed by Apple Inc. Macs are known for their ease of use and minimalist designs, and are popular among students, creative professionals, and software engineers. The current lineup includes the MacBook Air and MacBook Pro laptops, as well as the iMac, Mac Mini, Mac Studio and Mac Pro desktops. Macs run the macOS operating system. The first Mac was released in 1984, and was advertised with the highly-acclaimed "1984" ad. After a period of initial success, the Mac languished in the 1990s, until co-founder Steve Jobs returned to Apple in 1997. Jobs oversaw the release of many successful products, unveiled the modern Mac OS X, completed the 2005-06 Intel transition, and brought features from the iPhone back to the Mac. During Tim Cook's tenure as CEO, the Mac underwent a period of neglect, but was later reinvigorated with the introduction of popular high-end Macs and the ongoing Apple sil ...

AppleCD
AppleCD is a range of SCSI-based CD-ROM drives for Apple Macintosh 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A/UX
A/UX is Apple Computer's Unix-based operating system for Macintosh computers, integrated with System 7's graphical interface and application compatibility. Launched in 1988 and discontinued in 1995 with version 3.1.1, it is Apple's first official Unix-based operating system. A/UX requires select 68k-based Macintosh models with an FPU and a paged memory management unit (PMMU), including the Macintosh II, SE/30, Quadra, and Centris series. Described by ''InfoWorld'' as "an open systems solution with the Macintosh at its heart", the operating system is based on UNIX System V Release 2.2. It includes some additional features from System V Releases 3 and 4 and BSD versions 4.2 and 4.3. It is POSIX- and System V Interface Definition (SVID)-compliant and includes TCP/IP networking from version 2 onward. Having a Unix-compatible, POSIX-compliant operating system made it possible for Apple to bid for large contracts to supply computers to U.S. federal government institutes. Features ...

NuBus
NuBus (pron. 'New Bus') is a 32-bit parallel computer bus, originally developed at MIT and standardized in 1987 as a part of the NuMachine workstation project. 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. Among its many advanced features for the era, NuBu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AAUI
Apple Attachment Unit Interface (AAUI) is a mechanical re-design by Apple of the standard Attachment Unit Interface (AUI) used to connect Ethernet transceivers to computer equipment. AUI was popular in the era before the dominance of 10BASE-T networking that started in the early 1990s; 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 much 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 50 Ω 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 aut ... [...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, allowing them to be connected together in a daisy chain without the need for hubs or other devices. Apple Device 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 allow ... [...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, a machine would feature multiple bus expansions slots, if any. However, there was never more than one PDS slot. 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 Motorola 68040-based Quadra 700. ...
