SPARCstation 1
The SPARCstation 1 (Sun 4/60, code-named ''Campus'') is the first of the SPARCstation series of SPARC-based workstations sold by Sun Microsystems. The design originated in 1987 by a Sun spin-off company, UniSun, which was soon re-acquired. The SPARCstation 1 has a distinctive slim enclosure (a square 3-inch-high " pizza box") and was first announced in April 1989; the first units shipped in July that year. Based on an LSI Logic RISC CPU running at 20 MHz, with a Weitek 3170 (or 3172) FPU coprocessor, it was the fourth Sun computer (after the 4/260, 4/110 and 4/280) to use the SPARC architecture and the first of the sun4c architecture. The motherboard has three SBus slots, built-in AUI Ethernet, 8 kHz audio, and a 5 MB/s SCSI-1 bus. The basic display runs at in 256 colours, and monitors shipped with the computer were 16 to 19 inch greyscale or colour. Sun released the SPARCstation 1+, an upgrade to the SPARCstation 1 which increased the clock speed of the CPU t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun Microsystems
Sun Microsystems, Inc., often known as Sun for short, was an American technology company that existed from 1982 to 2010 which developed and sold computers, computer components, software, and information technology services. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, Reduced instruction set computer, RISC processors, thin client computing, and virtualization, virtualized computing. At its height, the Sun headquarters were in Santa Clara, California (part of Silicon Valley), on the former west campus of the Agnews Developmental Center. Sun products included computer servers and workstations built on its own Reduced instruction set computer, RISC-based SPARC processor architecture, as well as on x86-based AMD Opteron and Intel Xeon processors. Sun also developed its own computer storage, storage systems and a suite of software products, including the Unix-based SunOS and later Solaris operating system, Solaris operating s ...

SBus
SBus is a computer bus system that was used in most SPARC-based computers (including all SPARCstations) from Sun Microsystems and others during the 1990s. It was introduced by Sun in 1989 to be a high-speed bus counterpart to their high-speed SPARC processors, replacing the earlier (and by this time, outdated) VMEbus used in their Motorola 68020- and 68030-based systems and early SPARC boxes. When Sun moved to open the SPARC definition in the early 1990s, SBus was likewise standardized and became IEEE-1496. In 1997 Sun started to migrate away from SBus to the Peripheral Component Interconnect (PCI) bus, and today SBus is no longer used. The industry's first third-party SBus cards were announced in 1989 by Antares Microsystems; these were a 10BASE2 Ethernet controller, a SCSI-SNS host adapter, a parallel port, and an 8-channel serial controller. The specification was published by Edward H. Frank and James D. Lyle. A technical guide to the bus was published in 1992 in book fo ...

Open Firmware
Open Firmware is a standard defining the interfaces of a computer firmware system, formerly endorsed by the Institute of Electrical and Electronics Engineers (IEEE). It originated at Sun Microsystems where it was known as OpenBoot, and has been used by multiple vendors including Sun Microsystems, Sun, Apple Inc., Apple, IBM and Arm Holdings, ARM. Open Firmware allows a system to load platform (computing), platform-independent device driver, drivers directly from a PCI device, improving compatibility. Open Firmware may be accessed through its command line interface, which uses the Forth programming language. History Open Firmware was described by Institute of Electrical and Electronics Engineers, IEEE standard as ''IEEE 1275-1994''. This standard was not reaffirmed by the Open Firmware Working Group (OFWG) since 1998, and was therefore officially withdrawn by IEEE in May 2005. Features Open Firmware defines a standard way to describe the hardware configuration of a syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIMM
A SIMM (single in-line memory module) is a type of memory module used in computers from the early 1980s to the early 2000s. It is a printed circuit board upon which multiple random-access memory Integrated circuit chips are attached to one or both sides. 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 1983 by James E.

Frog Design
frog (styled as ''"frog, part of Capgemini Invent"'') is a global creative and design consultancy founded in 1969 by industrial designer Hartmut Esslinger in Mutlangen, Germany, where it was initially named “esslinger design”. Soon after the company moved to Altensteig, Germany, and then opened a new studio in Palo Alto, California, and ultimately to its current headquarters in San Francisco, California. The company has studios in North and Central America, Europe, and Asia. The name was changed to frog design in 1982 (the name originating from an acronym for Esslinger's home country, the Federal Republic of Germany; it was originally styled exclusively in lower-case as an expression of its belief in a democratic place of work, where ideas are openly and freely shared, and in opposition to the capitalization of nouns in German). The brand was once again restyled as frog in 2011 to signify an expanded portfolio of services that included strategy and organization activation ...

IBM PC Compatible
An IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its subsequent models. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC and is capable of using interchangeable commodity hardware such as expansion cards. Initially such computers were referred to as PC clones, IBM clones or IBM PC clones, but the term "IBM PC compatible" is now a historical description only, as the vast majority of microcomputers produced since the 1990s are IBM compatible. IBM itself no longer sells personal computers, having sold its division to Lenovo in 2005. " Wintel" is a similar description that is more commonly used for modern computers. The designation "PC", as used in much of personal computer history, has not meant "pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
