Macintosh IIvx
The Macintosh IIvx is a personal computer designed, manufactured and sold by Apple Computer from October 1992 to October 1993. It is the last of the Macintosh II family of Macintosh computers. The IIvx was introduced at the same time as the Macintosh IIvi, with both models using the same metal case design as the earlier Performa 600 and Performa 600CD. Like the Performa 600CD, the IIvx could be equipped with an internal double-speed CD-ROM drive. The IIvx was described in a ''MacWorld'' magazine review as having "the best price-to-performance ratio of any computer Apple has ever built." The list price for a machine with an hard drive, main memory, and of video memory was US$2,949. Adding the CD-ROM and upgrading to of main memory and video memory increased the price to US$3,219, which ''Macworld'' deemed to be "the best CD-ROM drive bargain ever offered". Overview The Mac IIvx began its life in development as a proof-of-concept to see how an internal CD-ROM drive could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh II Family
The Macintosh II is a family of personal computers that was designed, manufactured and sold by Apple Computer, Inc. from 1987 to 1993. The Macintosh II was the initial model, representing the high-end of the Macintosh line for the time. Over the course of the next six years, seven more models were produced, culminating with the short-lived Macintosh IIvi and Macintosh IIvx models. Apple retired the Macintosh II name when it moved to Motorola 68040 processors; the Centris and Quadra names were used instead. Features Unlike prior Macintosh models, which are "all-in-one" designs, the Macintosh II models are "modular" systems which do not include built-in monitors and are expandable. Beginning with the Macintosh II and culminating in the Macintosh IIfx, the Macintosh II family was Apple's high-end line from 1987 until the introduction of the Motorola 68040-based Macintosh Quadra computers in 1991. Expansion was provided by way of NuBus, which become the standard expansion bus for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh IIci
The Macintosh IIci is a personal computer designed, manufactured, and sold by Apple Computer, Inc. from September 1989 to February 1993. It is a more powerful version of the Macintosh IIcx, released earlier that year, and shares the same compact case design. With three NuBus expansion slots and a Processor Direct Slot, the IIci also improved upon the IIcx's 16 MHz Motorola 68030 CPU and 68882 FPU, replacing them with 25 MHz versions of these chips. The Macintosh Quadra 700 was introduced at the end of 1991 as Apple's mainstream workstation product to replace the IIci, albeit at a significantly higher price point: by this time, Apple authorized resellers were offering entry-level IIci systems for US$4,000 or less, whereas the Quadra 700 entered the market above US$6,000. Because of this, Apple continued to sell the IIci until early 1993 when the less expensive Quadra 650 and comparably-priced Quadra 800 were introduced. Hardware The IIci introduced several techn ...

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 ...

68k Macintosh Computers
The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel's x86 microprocessors. They were best known as the processors used in the early Apple Macintosh, the Sharp X68000, the Commodore Amiga, the Sinclair QL, the Atari ST, the Sega Genesis (Mega Drive), the Capcom System I (Arcade), the AT&T UNIX PC, the Tandy Model 16/16B/6000, the Sun Microsystems Sun-1, Sun-2 and Sun-3, the NeXT Computer, NeXTcube, NeXTstation, and NeXTcube Turbo, the Texas Instruments TI-89/TI-92 calculators, the Palm Pilot (all models running Palm OS 4.x or earlier) and the Space Shuttle. Although no modern desktop computers are based on processors in the 680x0 series, derivative processors are still widely used in embedded systems. Motorola ceased development of the 680x0 series arc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh II
The Macintosh II is a personal computer designed, manufactured, and sold by Apple Computer from March 1987 to January 1990. Based on the Motorola 68020 32-bit CPU, it is the first Macintosh supporting color graphics. When introduced, a basic system with monitor and 20 MB hard drive cost . With a 13-inch color monitor and 8-bit display card the price was around . This placed it in competition with workstations from Silicon Graphics, Sun Microsystems, and Hewlett-Packard. The Macintosh II was the first computer in the Macintosh line without a built-in display; a monitor rested on top of the case like the IBM Personal Computer and Amiga 1000. It was designed by hardware engineers Michael Dhuey (computer) and Brian Berkeley (monitor) and industrial designer Hartmut Esslinger (case). Eighteen months after its introduction, the Macintosh II was updated with a more powerful CPU and sold as the Macintosh IIx. In early 1989, the more compact Macintosh IIcx was introduced at a price simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MacWEEK
''MacWEEK'' was a controlled-circulation weekly Apple Macintosh trade journal based in San Francisco founded by Michael Tchong, John Anderson, Glenn Patch, Dick Govatski, and Michael F. Billings. It featured a back-page rumor column penned by the pseudonymous Mac the Knife. Founded in 1987, it was acquired by Ziff-Davis in 1988. In 1998, as part of a strategy change, the print publication was relaunched as ''eMediaWeekly'', which caused a number of its existing sponsors to withhold their advertising. ''eMediaWeekly'' was published from August 24, 1998 to February 1, 1999. The online edition of MacWEEK continued for several years, originally under the editorial management of MacWEEK staff members and later under the management of former Macworld editors. It was later shuttered in favor of Mac Publishing's Macworld and MacCentral sites. Rumors about Apple and its products were often published in MacWEEK which essentially became the source of record. Apple employees, following the ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorola 68040
The Motorola 68040 ("''sixty-eight-oh-forty''") is a 32-bit microprocessor in the Motorola 68000 series, released in 1990. It is the successor to the 68030 and is followed by the 68060, skipping the 68050. In keeping with general Motorola naming, the 68040 is often referred to as simply the '040 (pronounced ''oh-four-oh'' or ''oh-forty''). The 68040 was the first 680x0 family member with an on-chip Floating-Point Unit (FPU). It thus included all of the functionality that previously required external chips, namely the FPU and Memory Management Unit (MMU), which was added in the 68030. It also had split instruction and data caches of 4 kilobytes each. It was fully pipelined, with six stages. Versions of the 68040 were created for specific market segments, including the 68LC040, which removed the FPU, and the 68EC040, which removed both the FPU and MMU. Motorola had intended the EC variant for embedded use, but embedded processors during the 68040's time did not need the powe ...

Macintosh Centris 650
The Macintosh Quadra 650, originally sold as the Macintosh Centris 650, is a personal computer designed, manufactured and sold by Apple Computer from February 1993 to September 1994. The Centris 650 was introduced alongside the smaller Macintosh Quadra 610, Centris 610 as the replacement for the Macintosh IIci, Macintosh IIvi, IIvi and Macintosh Quadra 700, Quadra 700, and it was intended as the start of the new midrange Macintosh Centris, 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 650 into the Quadra family. The Quadra 650 was discontinued without a direct replacement in September 1994, although the recently introduced Power Macintosh 7100, which has the same Macintosh IIvx, IIvx form factor as the 650, had a similar target audience and was sold in the same price range.

Power Macintosh 7100
The Power Macintosh 7100 is a personal computer that was designed, manufactured and sold by Apple Computer from March 1994 to January 1996. It is the mid-range machine of the first generation of Power Macintosh line, between the Power Macintosh 6100 and the 8100. The 7100 re-used the Macintosh IIvx case with few changes. The initial version of the 7100 was powered by a PowerPC 601, and an version replaced it in January 1995. The 7100 was succeeded in August 1995 by two new models, the Power Macintosh 7200 and the Power Macintosh 7500, though sales of the 7100 continued into early 1996. Models The 7100AV variants include a 2 MB VRAM card with S-Video in/out. The non-AV 7100s have a video card containing 1 MB VRAM which was expandable to 2 MB, and no S-Video in/out capability. Apple did not release a "DOS Compatible" card for the 7100 as they had for some contemporary Macintosh Quadra models, opting instead to offer the 7100 bundled with the SoftWindows emulator at a price o ...

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. ...

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] |
