Macintosh II Series
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] |
Motorola 68000
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal data bus. The address bus is 24 bits and does not use memory segmentation, which made it easier to program for. Internally, it uses a 16-bit data arithmetic logic unit (ALU) and two more 16-bit ALUs used mostly for addresses, and has a 16-bit external data bus. For this reason, Motorola termed it a 16/32-bit processor. As one of the first widely available processors with a 32-bit instruction set, and running at relatively high speeds for the era, the 68k was a popular design through the 1980s. It was widely used in a new generation of personal computers with graphical user interfaces, including the Macintosh 128K, Amiga, Atari ST, and X68000. Th ...

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 IIcx
The Macintosh IIcx is a personal computer designed, manufactured and sold by Apple Computer, Inc. from March 1989 to March 1991. Introduced six months after the Macintosh IIx, the IIcx resembles the IIx and provides the same performance, but is seven inches narrower, ten pounds lighter, and quieter due to a smaller internal fan. The relative compactness results in three NuBus slots being available, compared with six on the IIx. The new case, Apple's first to be designed to operate in either a horizontal or vertical orientation, remained in use for its successors the Macintosh IIci and Quadra 700. The idea for vertical orientation, one of the first minitower cases, was suggested by Apple CEO John Sculley, who was running out of space on his desk, despite the fact that the new layout actually took more space once the monitor was taken into account. The model was designated IIcx for ''compact'' (echoing the earlier Apple IIc compact model in the Apple II series), and the ''x'' w ...

Macintosh IIx
The Macintosh IIx is a personal computer designed, manufactured, and sold by Apple Computer from September 1988 to October 1990. This model was introduced as an update to the original Macintosh II, replacing the 16 MHz Motorola 68020 CPU and 68881 FPU with a 68030 CPU and 68882 FPU running at the same clock speed. The initial price of the IIx was or for the version with a 40 MB hard drive. The 800 KB floppy drive was replaced with a 1.44 MB SuperDrive; the IIx is the first Macintosh to include this as standard. The Mac IIx included 0.25 KiB of L1 instruction CPU cache, 0.25 KiB of L1 data cache, a 16 MHz bus (1:1 with CPU speed), and supported up to System 7.5.5. The IIx was the second of three Macintosh models to use this case allowing dual floppy drives and 6 NuBus slots; the last model was the Macintosh IIfx. Apple's nomenclature of the time used the "x" to indicate the presence of the 68030 CPU as used in the Macintosh IIcx The Macintosh IIcx is a person ...

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 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 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 controversy about performance cl ...

PowerBook
The PowerBook (known as Macintosh PowerBook before 1997) is a family of Macintosh laptop computers designed, manufactured and sold by Apple Computer from 1991 to 2006. During its lifetime, the PowerBook went through several major revisions and redesigns, often being the first to incorporate features that would later become standard in competing laptops. The PowerBook line was targeted at the professional market. In 1999, the line was supplemented by the home and education-focused iBook family. The PowerBook was replaced by the MacBook Pro in 2006 as part of the Mac transition to Intel processors. 680x0-based models PowerBook 100 series In October 1991, Apple released the first three PowerBooks: the low-end PowerBook 100, the more powerful PowerBook 140, and the high end PowerBook 170, the only one with an active matrix display. These machines caused a stir in the industry with their compact dark grey cases, built-in trackball, and the innovative positioning of the keybo ...

68030
The Motorola 68030 ("''sixty-eight-oh-thirty''") is a 32-bit microprocessor in the Motorola 68000 family. It was released in 1987. The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced ''oh-three-oh'' or ''oh-thirty''). The 68030 is essentially a 68020 with a memory management unit (MMU) and instruction and data caches of 256 bytes each. It added a burst mode (computing), burst mode for the caches, where four longwords can be loaded into the cache in a single operation. The MMU was mostly compatible with the external Motorola 68851, 68851 that would be used with the 68020, but being internal allowed it to access memory one cycle faster than a 68020/68851 combo. The 68030 did not include a built-in floating-point unit (FPU), and was generally used with the Motorola 68881, 68881 and the faster Motorola 68882, 68882. The addition of the FPU was a major d ...

Macintosh Performa
The Macintosh Performa is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. from 1992 to 1997. The Performa brand re-used models from Apple's Quadra, Centris, LC, and Power Macintosh families with model numbers that denoted included software packages or hard drive sizes. Whereas non-Performa Macintosh computers were sold by Apple Authorized Resellers, the Performa was sold through big-box stores and mass-market retailers such as Good Guys, Circuit City, and Sears. The initial series of models consisted of the Macintosh Classic II-based Performa 200, the LC II-based Performa 400, and the IIvi-based Performa 600. After releasing a total of sixty-four different models, Apple retired the Performa brand in early 1997, shortly after release of the Power Macintosh 5500, 6500, 8600 and 9600, as well as the return of Steve Jobs to the company. The Performa brand's lifespan coincided with a period of significant financial turmoil at Apple du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh LC Family
The Macintosh LC is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. from 1990 to 1997. Introduced alongside the Macintosh IIsi and Macintosh Classic as part of a new wave of lower-priced Macintosh computers, the LC offered the same overall performance as the Macintosh II for half the price. Part of Apple's goal was to produce a machine that could be sold to school boards for the same price as an Apple IIGS, a machine that was very successful in the education market. Not long after the Apple IIe Card was introduced for the LC, Apple officially announced the retirement of the IIGS, as the company wanted to focus its sales and marketing efforts on the LC. The original Macintosh LC was introduced on October 1990, with updates in the form of the LC II and LC III in 1992 and early 1993. These early models all shared the same pizza box form factor, and were joined by the Macintosh LC 500 series of all-in-one desktop machines in mid-1993. ...

Workstation
A workstation is a special computer designed for technical or scientific applications. Intended primarily to be used by a single user, they are commonly connected to a local area network and run multi-user operating systems. The term ''workstation'' has been used loosely to refer to everything from a mainframe computer terminal to a PC connected to a network, but the most common form refers to the class of hardware offered by several current and defunct companies such as Sun Microsystems, Silicon Graphics, Apollo Computer, DEC, HP, NeXT, and IBM which powered the 3D computer graphics revolution of the late 1990s. Workstations offer higher performance than mainstream personal computers, especially in CPU, graphics, memory, and multitasking. Workstations are optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulations like computational fluid dynamics, animation, medical imaging, image rendering, and ...

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 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 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 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. The standard, as-shipped configuration for the 900 was 4 MB. The high RAM and storage capacity, alon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
