PowerBook 2400c
The PowerBook 2400c (codenames: "Comet", "Nautilus") is a subnotebook in Apple Computer's PowerBook range of Macintosh computers, weighing . Manufacturing was contracted to Japan IBM. In a return to the PowerBook 100 form factor, it was introduced in May 1997 as a late replacement for the PowerBook Duo 2300c, which had been the last of the subnotebook PowerBook Duo series. The 2400c was discontinued in March 1998, with no immediate replacement — the model that followed it was the much larger PowerBook G3 Series (known as "Wallstreet"/"Mainstreet"). However, in Japan a 2400c with a 240 MHz CPU (codenamed "Mighty Cat") was offered shortly after the original model's discontinuation, until the end of the year. Overview The 2400c uses the same PowerPC 603e processor as the preceding Duo 2300c, but at a much higher CPU clock — 180 instead of 100 MHz. However, the 2400 is unable to utilize the DuoDock like the 2300c was, making the lack of an internal removable drive much ...

Macintosh External Disk Drive
The Macintosh External Disk Drive is the original model in a series of external -inch floppy disk drives manufactured and sold by Apple Computer exclusively for the Macintosh series of computers introduced in January 1984. Later, Apple would unify their external drives to work cross-platform between the Macintosh and Apple II product lines, dropping the name "Macintosh" from the drives. Though Apple had been producing external floppy disk drives prior to 1984, they were exclusively developed for the Apple II, III and Lisa computers using the industry standard -inch flexible disk format. The Macintosh external drives were the first to widely introduce Sony's new -inch rigid disk standard commercially and throughout their product line. Apple produced only one external -inch drive exclusively for use with the Apple II series called the ''Apple UniDisk 3.5''. 400K The original Macintosh External Disk Drive (M0130) was introduced with the Macintosh on January 24, 1984. However, i ...

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 ...

PowerBook Duo 2300c
The PowerBook Duo is a line of subnotebooks manufactured and sold by Apple Computer from 1992 until 1997 as a more compact companion to the PowerBook line. Improving upon the PowerBook 100's portability (its immediate predecessor and Apple's third-smallest laptop), the Duo came in seven different models. They were the Duo 210, 230, 250, 270c, 280, 280c, and 2300c, with the 210 and 230 being the earliest, and the 2300c being the final incarnation before the entire line was dropped in early 1997. Weighing and slightly smaller than a sheet of paper at , and only thick, it was the lightest and smallest of all of Apple's PowerBooks at the time, and remains one of Apple's smallest notebooks ever produced. Only the MacBook Air, the Retina MacBook Pro and the Retina MacBook weigh less, though they are wider and deeper (but considerably thinner). The Duo had the most in common with the original MacBook Air which only included one USB 2.0 port, one video port (requiring an adapter) an ...

PowerPC G3
The PowerPC 7xx is a family of third generation 32-bit PowerPC microprocessors designed and manufactured by IBM and Motorola (spun off as Freescale Semiconductor bought by NXP Semiconductors). This family is called the PowerPC G3 by its well-known customer Apple Inc., which introduced it on November 10, 1997. The term "PowerPC G3" is often, and incorrectly, imagined to be a microprocessor when in fact a number of microprocessors from different vendors have been used. Such designations were applied to Macintosh computers such as the PowerBook G3, the IMac G3, multicolored iMacs, iBooks and several desktops, including both the Power Macintosh G3, Beige and Power Macintosh G3 (Blue & White), Blue and White Power Macintosh G3s. The low power requirements and small size made the processors ideal for laptops and the name lived out its last days at Apple in the iBook. The 7xx family is also widely used in embedded devices like printers, routers, storage devices, spacecraft, and video ga ...

Daughter Card
In computing, an expansion card (also called an expansion board, adapter card, peripheral card or accessory card) is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computer's motherboard (see also backplane) to add functionality to a computer system. Sometimes the design of the computer's case and motherboard involves placing most (or all) of these slots onto a separate, removable card. Typically such cards are referred to as a riser card in part because they project upward from the board and allow expansion cards to be placed above and parallel to the motherboard. Expansion cards allow the capabilities and interfaces of a computer system to be extended or supplemented in a way appropriate to the tasks it will perform. For example, a high-speed multi-channel data acquisition system would be of no use in a personal computer used for bookkeeping, but might be a key part of a system used for ind ...

MacBook (12-inch)
The 12-inch MacBook (also called the Retina MacBook, officially marketed as the new MacBook) is a discontinued Mac laptop made by Apple Inc., which sat between the MacBook Air and MacBook Pro in Apple's laptop lineup. It was introduced in March 2015. It was more compact than any other notebook in the MacBook family at the time and included a Retina display, fanless design, a Butterfly keyboard with lower key travel. It only had a single USB-C port, used for both power and data, as well as a 3.5mm headphone jack. It was released in 2015, revised in 2017, and discontinued in July 2019, a year after the release of the MacBook Air with Retina display. Overview The MacBook was announced at an Apple special event on March 9, 2015, and was released a month later on April 10. It employed Intel's Broadwell Core M processors at a TDP of around 4.5 Watt to allow for a fanless design and a logic board that is much smaller than in previous MacBooks. It had a similar appearance t ...

PowerBook G4
The PowerBook G4 is a series of notebook computers manufactured, marketed, and sold by Apple Computer between 2001 and 2006 as part of its PowerBook line of notebooks. The PowerBook G4 runs on the RISC-based PowerPC G4 processor, designed by the AIM (Apple/ IBM/Motorola) development alliance and initially produced by Motorola. It was built later by Freescale, after Motorola spun off its semiconductor business under that name in 2004. The PowerBook G4 has two different designs: one enclosed in a titanium body with a translucent black keyboard and a 15-inch screen; and another in an aluminum body with an aluminum-colored keyboard, in 12-inch, 15-inch, and 17-inch sizes. Between 2001 and 2003, Apple produced the titanium PowerBook G4; between 2003 and 2006, the aluminum models were produced. Both models were hailed for their modern design, long battery life, and processing power. When the aluminum PowerBook G4s were first released in January 2003, 12-inch and 17-inch models were intr ...

IBook
iBook is a line of laptop computers designed, manufactured, and sold by Apple Computer from 1999 to 2006. The line targeted entry-level, consumer and education markets, with lower specifications and prices than the PowerBook, Apple's higher-end line of laptop computers. It was the first mass consumer product to offer Wi-Fi network connectivity, which was then branded by Apple as AirPort. The iBook had three different designs during its lifetime. The first, known as the "Clamshell", was inspired by the design of Apple's popular iMac line at the time. It was a significant departure from previous portable computer designs due to its shape, bright colors, incorporation of a handle into the casing, lack of a display closing latch, lack of a hinged cover over the external ports and built-in wireless networking. Two years later, the second generation abandoned the original form factor in favor of a more conventional, rectangular design. In October 2003, the third generation was intro ...

Active Matrix
Active matrix is a type of addressing scheme used in flat panel displays. In this method of switching individual elements (pixels), each pixel is attached to a transistor and capacitor ''actively'' maintaining the pixel state while other pixels are being addressed, in contrast with the older passive matrix technology in which each pixel must maintain its state passively, without being driven by circuitry. Active matrix technology was invented by Bernard J. Lechner at RCA, using MOSFETs (metal-oxide-semiconductor field-effect transistors). Active matrix technology was first demonstrated as a feasible device using thin-film transistors (TFTs) by T. Peter Brody, Fang Chen Luo and their team at the Thin-Film Devices department of Westinghouse Electric Corporation in 1974, and the term was introduced into the literature in 1975. Given an ''m'' × ''n'' matrix, the number of connectors needed to address the display is ''m'' + ''n'' (just like in passive matrix techn ...

CD-ROM
A CD-ROM (, compact disc read-only memory) is a type of read-only memory consisting of a pre-pressed optical compact disc that contains data. Computers can read—but not write or erase—CD-ROMs. Some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data (such as software or digital video) is only usable on a computer (such as ISO 9660 format PC CD-ROMs). During the 1990s and early 2000s, CD-ROMs were popularly used to distribute software and data for computers and fifth generation video game consoles. DVD started to replace it in these roles starting in the early 2000s. History The earliest theoretical work on optical disc storage was done by independent researchers in the United States including David Paul Gregg (1958) and James Russel (1965–1975). In particular, Gregg's patents were used as the basis of the LaserDisc specification that was co-developed between MCA and Philips after MCA purchased ...

PowerPC 603e
The PowerPC 600 family was the first family of PowerPC microprocessor, 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 ...
