Compatibility Card
A compatibility card is an expansion card for computers that allows it to have hardware emulation with another device. While compatibility cards date back at least to the Apple II family, the majority of them were made for 16-bit computers, often to maintain compatibility with the IBM PC. The most popular of these were for Macintosh systems that allowed them to emulate Windows PCs via NuBus or PCI; Apple had released several such cards themselves. Compatibility cards by system Apple II * The Z-80 SoftCard made the Apple II and Apple II Plus compatible with CP/M by way of a Zilog Z80 processor, and was followed up by the Premium SoftCard IIe for the Apple IIe.

Apple IIe Card
The Apple IIe Card is a hardware emulation board, also referred to as compatibility card, which allows compatible Macintosh computers to run software designed for the Apple II series of computers (with the exception of the Apple IIGS, IIGS). Released in March 1991 for use with the LC family, Apple targeted the card at its widely dominated educational market to ease the transition from Apple II-based classrooms, with thousands of entrenched educational software titles, to Macintosh-based classrooms. Overview Well into the 1990s, most schools still had a substantial investment in Apple II computers and software in their classrooms and labs. However, by that period Apple was looking to phase out the Apple II line, and so introduced the Apple IIe Card as a means to transition Apple II educators (and to a smaller degree, home and small business users) by migrating them over to the Macintosh. By adding the optional PDS card to low cost Macintosh computers, it provided backwards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh 128K
The Apple Macintosh—later rebranded as the Macintosh 128K—is the original Apple Inc., Apple Macintosh personal computer. It played a pivotal role in establishing desktop publishing as a general office function. The motherboard, a CRT monitor, and a floppy drive were housed in a beige case with integrated carrying handle; it came with a keyboard and single-button mouse. It sold for . The Macintosh was introduced by a television commercial entitled "1984 (advertisement), 1984" shown during Super Bowl XVIII on January 22, 1984 and directed by Ridley Scott. Sales of the Macintosh were strong from its initial release on January 24, 1984, and reached 70,000 units on May 3, 1984. Upon the release of its successor, the Macintosh 512K, it was rebranded as the Macintosh 128K. The computer's model number was M0001.

MacCharlie
The MacCharlie is a hardware add-on for the Apple Macintosh that was made by Dayna Communications. The name refers to an IBM PC advertising campaign of the time featuring Charlie Chaplin's "Little Tramp" character. It allows users to run DOS software for the IBM PC by clipping a unit onto the chassis of the Macintosh 128K, as well as a keyboard extender to provide the function keys and numeric keypad that are absent from Apple's original keyboard. The clip-on unit sits to the side of the Mac and, like the contemporary Amiga Sidecar, contains essentially a complete IBM PC compatible with an 8088 processor, 256 KB of RAM (expandable to 640 KB) and a single 5.25" floppy disk drive that stores 360 KB. A second floppy drive can be added. While running DOS software, users can still access the Macintosh menu bar and desk accessories. However, the DOS environment, which runs in a window, is text-only and does not permit Macintosh applications to run concurrently while in use. Ma ...

Dayna Communications
Dayna Communications, Inc., was a privately-held American computer company, active from 1984 to 1997 and based in Salt Lake City, Utah. It primarily manufactured networking products for Apple Computer's computing platforms, including the Macintosh, PowerBook and Newton (although some of its later networking products were platform-independent and could work on PCI-based IBM PC compatibles). In 1997, the company was acquired by Intel for nearly $14 million. History Dayna Communications was founded by William Sadleir in Salt Lake City in 1984, with $1.6 million in start-up capital. In May 1985, the company delivered the MacCharlie, a hardware add-on for the Macintosh 128K that was essentially a headless IBM PC clone, complete with one or two 5.25-inch floppy drives, that clipped onto the side of the Mac. It connected to the Mac via a serial cable; users could run PC software through a terminal application provided through included floppy disks. The product received ...

Power Macintosh 4400
The Power Macintosh 4400 (sold as the Power Macintosh 7220 in some markets) is a personal computer designed, manufactured and sold by Apple Computer, Inc. from November 1996 to February 1998. It differs from prior desktop Macintosh models in that it was built with industry-standard components such as an IDE hard drive and an ATX-like power supply. The 4400 was introduced to the market at a time when several Macintosh clones were available on the market, often at prices lower than Apple's. The "Tanzania" logic board in the 4400 was an Apple design but had only been used in clones up to this point. MacWEEK's review described the case as "Strange in the Apple brood; when compared with PCs it fits right in with the flock. It is contained in a stock desktop PC case fitted with Apple's distinctive curved nose piece. The back is industrial-looking, while bent sheet metal fills the case's insides, sharp edges and all. The IDE drive sits on end, while the Comm II slot (occupied with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Macintosh 7300
The Power Macintosh 7300 (also sold with server software as the Apple Workgroup Server 7350) is a personal computer designed, manufactured and sold by Apple Computer from February 1997 to November 1997. It was introduced with 166, 180 and 200 MHz CPUs in February 1997 alongside the Power Macintosh 8600 and 9600. The 7300 replaced both the Power Macintosh 7200 and 7600, replacing the only remaining first-generation PowerPC system in Apple's lineup. MacUser Magazine's review says the 7300 "offers the most satisfying improvement" of the new machines introduced in early 1997 due to a significant performance jump from its predecessors, as well as offering 50% faster CD-ROM and hard disk space. The 7300 was replaced by the Power Macintosh G3 desktop model in November 1997. Workgroup Server 7350 continued to be sold until March 1998 when the Macintosh Server G3 was introduced.

Power Macintosh 7200
The Power Macintosh 7200 (sold as a Power Macintosh 8200 in Europe) is a personal computer designed, manufactured, and sold by Apple Computer from August 1995 to February 1997. The 90 MHz model was sold in Japan as the Power Macintosh 7215, and the 120 MHz model with bundled server software as the Apple Workgroup Server 7250. When sold as the 8200, it used the Quadra 800/ Power Mac 8100's mini-tower form factor. The 7200 was introduced alongside the Power Macintosh 7500 and 8500 at the 1995 MacWorld Expo in Boston. Apple referred to these machines collectively as the "Power Surge" line, communicating that this second generation of PowerPC machines offered a significant speed improvement over their predecessors. Introduced as a successor to the Power Macintosh 7100, the 7200 represents the low end of this generation of Power Macintosh, which replaced NuBus with PCI. It shares the 7500's "Outrigger" case. At launch, the 7200 was available with processor speeds of 75 and 90 MHz, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyrix 6x86
The Cyrix 6x86 is a line of sixth-generation, 32-bit x86 microprocessors designed and released by Cyrix in 1995. Cyrix, being a fabless company, had the chips manufactured by IBM and SGS-Thomson. The 6x86 was made as a direct competitor to Intel's Pentium microprocessor line, and was pin compatible. During the 6x86's development, the majority of applications (office software as well as games) performed almost entirely integer operations. The designers foresaw that future applications would most likely maintain this instruction focus. So, to optimize the chip's performance for what they believed to be the most likely application of the CPU, the integer execution resources received most of the transistor budget. This would later prove to be a strategic mistake, as the popularity of the P5 Pentium caused many software developers to hand-optimize code in assembly language, to take advantage of the P5 Pentium's tightly pipelined and lower latency FPU. For example, the highly anticip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentium
Pentium is a brand used for a series of x86 architecture-compatible microprocessors produced by Intel. The original Pentium processor from which the brand took its name was first released on March 22, 1993. After that, the Pentium II and Pentium III were released. In their form , Pentium processors are considered entry-level products that Intel rates as "two stars", meaning that they are above the low-end Atom and Celeron series, but below the faster Intel Core lineup, and workstation/server Xeon series. , Pentium processors have little more than their name in common with earlier Pentiums, which were Intel's flagship processor for over a decade until the introduction of the Intel Core line in 2006. They are based on both the architecture used in Atom and that of Core processors. In the case of Atom architectures, Pentiums are the highest performance implementations of the architecture. Pentium processors with Core architectures prior to 2017 were distinguished from the fast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyrix 5x86
The Cyrix 5x86 was a line of x86 microprocessors designed by Cyrix and released on June 5 of 1995. Cyrix, being a fabless company, had the chips manufactured by IBM. The line came out about 5 months before the more famous Cyrix 6x86. The Cyrix 5x86 was one of the fastest CPUs ever produced for Socket 3 computer systems. With better performance in most applications than an Intel Pentium processor at 75 MHz, the Cyrix Cx5x86 filled a gap by providing a medium-performance processor option for 486 Socket 3 motherboards (which are incapable of handling Intel's Pentium CPUs, apart from the Pentium Overdrive). The IBM 5x86C is an IBM branded and produced version of the Cyrix-designed Cyrix Cx5x86 CPU. Previous IBM x86 processors, IBM 386SLC and IBM 486SLC, were based on modified Intel designs. Design The Cyrix 5x86 processor, codename "M1sc", was based on a scaled-down version of the "M1" core used in the Cyrix 6x86, which provided 80% of the performance for a 50% de ...
