Power Macintosh 6100
The Power Macintosh 6100 (also sold as the Performa 6110 – 6118 and the Workgroup Server 6150) is a personal computer designed, manufactured and sold by Apple Computer from March 1994 to March 1996. It is the first computer from Apple to use the new PowerPC processor created by IBM and Motorola. The low-profile ("pizza-box") case was inherited from the Centris/Quadra 610 and 660AV models, and replaced the Macintosh Quadra series that used the Motorola 68040 processor, Apple's previous high-end workstation line. For the consumer market, the 6100 was re-branded as a Macintosh Performa with model numbers in the 6110 – 6118 range denoting bundled software and hard drive sizes. An Apple Multiple Scan 15 Display and AppleDesign Keyboard were included as part of the package. For the server market, a variant was offered with additional server software, called the Apple Workgroup Server 6150. The 6100 was discontinued without a direct replacement.

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 ...

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 ...

Stanley Jordan
Stanley Jordan (born July 31, 1959) is an American jazz guitarist noted for his playing technique, which involves tapping his fingers on the fretboard of the guitar with both hands. Music career Jordan was born in Chicago, Illinois, United States. When he was six, he started on piano, then at eleven switched to guitar. He later began playing in rock and soul bands. In 1976, he won an award at the Reno Jazz Festival. At Princeton University, he studied music theory and composition with Milton Babbitt and computer music with Paul Lansky. He also took freshman calculus with Edward Nelson. While at Princeton he played with Benny Carter and Dizzy Gillespie. In 1985, Bruce Lundvall became president of Blue Note Records and Stanley Jordan was the first person he signed. Blue Note released his album ''Magic Touch'', which sat at No.1 on ''Billboard''s jazz chart for 51 weeks, setting a record. Touch technique Normally, a guitarist uses two hands to play each note.

Game Port
The game port is a device port that was found on IBM PC compatible and other computer systems throughout the 1980s and 1990s. It was the traditional connector for joystick input, and occasionally MIDI devices, until made obsolete by USB in the late 1990s. Originally located on a dedicated Game Control Adapter expansion card, the game port was later integrated with PC sound cards, and still later on the PC's motherboard. During the transition to USB, many input devices used the game port and a USB adapter dongle was included for systems without a game port. History The game port first appeared during the initial launch of the original IBM PC in 1981, in the form of an optional US$55 expansion card known as the Game Control Adapter. The design allowed for four analog axes and four buttons on one port, allowing two joysticks or four paddles to be connected via a special "Y-splitter" cable. At the time there was no industry standard for controller ports, although the Atari joy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Graphics Array
Video Graphics Array (VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the PC industry within three years. The term can now refer to the computer display standard, the 15-pin D-subminiature VGA connector, or the 640×480 resolution characteristic of the VGA hardware. VGA was the last IBM graphics standard to which the majority of PC clone manufacturers conformed, making it the lowest common denominator that virtually all post-1990 PC graphics hardware can be expected to implement. IBM intended to supersede VGA with the Extended Graphics Array (XGA) standard, but failed. Instead, VGA was adapted into many extended forms by third parties, collectively known as Super VGA, then gave way to custom graphics processing units which, in addition to their proprietary interfaces and capabilities, continue to implement common VGA graphics modes and interfaces to the pres ...

SIMM
A SIMM (single in-line memory module) is a type of memory module containing random-access memory used in computers from the early 1980s to the early 2000s. It differs from a dual in-line memory module (DIMM), the most predominant form of memory module since the late 1990s, in that the contacts on a SIMM are redundant on both sides of the module. SIMMs were standardised under the JEDEC JESD-21C standard. Most early PC motherboards (8088-based PCs, XTs, and early ATs) used socketed DIP chips for DRAM. As computer memory capacities grew, memory modules were used to save motherboard space and ease memory expansion. Instead of plugging in eight or nine single DIP chips, only one additional memory module was needed to increase the memory of the computer. History SIMMs were invented in 1982 by James J. Parker at Zenith Microcircuits and the first Zenith Microcircuits customer was Wang Laboratories. Wang Laboratories tried to patent it and were granted a patent in April 1987. Th ...

Intel 80486
The Intel 486, officially named i486 and also known as 80486, is a microprocessor. It is a higher-performance follow-up to the Intel 386. The i486 was introduced in 1989. It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386. It was the first tightly- pipelined x86 design as well as the first x86 chip to include more than one million transistors. It offered a large on-chip cache and an integrated floating-point unit. A typical 50 MHz i486 executes around 40 million instructions per second (MIPS), reaching 50 MIPS peak performance. It is approximately twice as fast as the i386 or i286 per clock cycle. The i486's improved performance is thanks to its five-stage pipeline with all stages bound to a single cycle. The enhanced FPU unit on the chip was significantly faster than the i387 FPU per cycle. The intel 80387 FPU ("i387") was a separate, optional math coprocessor that was installed in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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. ...
