Power Macintosh 5200 LC
The Power Macintosh 5200 LC and Power Macintosh 5300 LC were a line of personal computers that are a part of Apple Computer's Power Macintosh, LC, and Performa families of Macintosh computers. When sold to the consumer market, the machines were marketed as variations of Performa 5200 and Performa 5300. The Power Macintosh 5200 LC was introduced in April 1995 with a PowerPC 603 CPU at 75 MHz as a PowerPC-based replacement of the Macintosh LC 500 series. Later models switched to the PowerPC 603e CPU and used model numbers above 5300, but kept the same motherboard design. Unlike previous education models, which prepended the model number with "LC", the 5200 / 5300 models use the Power Macintosh designation of Apple's main workstation line of the time, with "LC" appended to the end. The 5200 is closely related to the 6200, which use the same logic boards in desktop cases without integrated monitors. In an editorial, MacWorld Magazine's Editor-In-Chief, Adrian Mello, w ...

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 ...

Apple Macintosh
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 s ...

PowerPC Macintosh Computers
PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple– IBM–Motorola alliance, known as AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors. PowerPC was the cornerstone of AIM's PReP and Common Hardware Reference Platform (CHRP) initiatives in the 1990s. Originally intended for personal computers, the architecture is well known for being used by Apple's Power Macintosh, PowerBook, iMac, iBook, eMac, Mac Mini, and Xserve lines from 1994 until 2005, when Apple migrated to Intel's x86. It has since become a niche in personal computers, but remains popular for embedded and high-performance processors. Its use in 7th generation of video game consoles and embedded ...

Macintosh LC
The Macintosh LC is a personal computer designed, manufactured, and sold by Apple Computer, Inc. from October 1990 to March 1992. Overview The first in the Macintosh LC family, the LC was introduced with the Macintosh Classic (a repackaging of the older Macintosh SE) and the Macintosh IIsi (a new entry-level machine for the Macintosh II series), and offered for half the price of the Macintosh II but significantly lesser in performance overall. The creation of the LC was prompted by Apple's desire to produce a product that could be sold to school boards for the same price as an Apple IIGS. It was designed for inexpensive manufacturing, with five major components that robots could assemble. The computer had a $2,400 list price; it and the new $600 12-inch color display were $3,500 less expensive than the Macintosh II. Not long after the Apple IIe Card was introduced for the LC, Apple quietly removed the IIGS from its price list, forceably retiring it, as the company wanted to fo ...

Shadow Mask
The shadow mask is one of the two technologies used in the manufacture of cathode-ray tube (CRT) televisions and computer monitors which produce clear, focused color images. The other approach is the aperture grille, better known by its trade name, Trinitron. All early color televisions and the majority of CRT computer monitors used shadow mask technology. Both of these technologies are largely obsolete, having been increasingly replaced since the 1990s by the liquid-crystal display (LCD). A shadow mask is a metal plate punched with tiny holes that separate the colored phosphors in the layer behind the front glass of the screen. Shadow masks are made by photochemical machining, a technique that allows for the drilling of small holes on metal sheets. Three electron guns at the back of the screen sweep across the mask, with the beams only reaching the screen if they pass through the holes. As the guns are physically separated at the back of the tube, their beams approach th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Quadra 630
The Macintosh Quadra 630 (also sold as the Macintosh LC 630 and Macintosh Performa 630) is a personal computer designed, manufactured and sold by Apple Computer from July 1994 to October 1995. It was introduced as the replacement for the Quadra 610, and was the least-expensive computer in the Macintosh lineup with prices starting at $1,199 USD. While Apple's transition to PowerPC CPUs had already begun with the introduction of the Power Macintosh a few months prior, the 630 was built around the older Motorola 68040 and 68LC040 chips. Two reasons were cited for this: One, the older chips were less expensive; and two, PowerPC-native education software was almost non-existent at the time. Also, existing PowerPC software had yet to be translated to non-English languages. The 630 was the last new Macintosh Quadra introduced, though the earlier Quadra 950 remained available longer. It was discontinued with no direct replacement; while the 630's form factor was retained with the Powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Conventional PCI
Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor's native bus. Devices connected to the PCI bus appear to a bus master to be connected directly to its own bus and are assigned addresses in the processor's address space. It is a parallel bus, synchronous to a single bus clock. Attached devices can take either the form of an integrated circuit fitted onto the motherboard (called a ''planar device'' in the PCI specification) or an expansion card that fits into a slot. The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of several slow Industry Standard Architecture (ISA) slots and one fast VESA Local Bus (VLB) slot as the bus configuration. It has subsequently been adopted for other computer types. Typica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faceplate (housing)
In engineering, a housing or enclosure is a container, a protective exterior (e.g. shell (structure), shell) or an enclosing structural element (e.g. chassis or exoskeleton) designed to enable easier handling, provide attachment points for internal mechanisms (e.g. mounting brackets for electrical components, electrical cable, cables and pipings), maintain cleanliness of the contents by shielding dirt/dust, fouling and other contaminations, or protect interior mechanisms (e.g. delicate integrated electrical fittings) from structural load, structural Stress (mechanics), stress and/or potential physical, thermal, chemical, biological or radiational damages from the surrounding environment. Housing may also be the body of a device, vital to its function. Description Housing is an exterior case or enclosure used to protect an interior mechanism. The housing prevents the interior mechanism from being fouled by outside debris. It may also have integrated fittings or brackets to keep in ...

Macworld
''Macworld'' is a website dedicated to products and software of Apple Inc., published by Foundry, a subsidiary of IDG Inc. It started life as a print magazine in 1984 and had the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, ''MacLife'' (formerly ''MacAddict''). ''Macworld'' was founded by David Bunnell and Cheryl Woodard (publishers) and Andrew Fluegelman (editor). It was the oldest Macintosh magazine still in publication, until September 10, 2014, when IDG, its parent company, announced it was discontinuing the print edition and laid off most of the staff, while continuing an online version. History of Macworld In 1997, the publication was renamed ''Macworld, incorporating MacUser'' (a name reflected subtly on the magazine's Table of Contents page) to reflect the consolidation of the Ziff-Davis-owned ''MacUser'' magazine into the International Data Group-owned ''Macworld'' wit ...
