NuBus was a considerable step forward compared to other interfaces of the day. At the time most computer bus systems were 8-bit, as were the computers they plugged into. However NuBus decided on a 32-bit interface because it was clear the market was headed in this direction. In addition, NuBus was agnostic about the processor itself. Most buses up to this point were basically the pins on the CPU run out onto the backplane, meaning that the cards had to conform to the signalling and data standards of the machine it was plugged into (be ...

More so than with any other period, the 32-bit / 64-bit era was the paramount staging ground of the "system wars". The "system wars" were a phenomenon in which people would attempt to evaluate the upcoming hardware of a system and purchase the system for that reason alone, speculating that the best games must be made for that hardware. Since the length of time systems spent in development had been steadily growing since the 8-bit era, and since a growing consumer awareness was making the development process more public than at any time in th ...

Amdahl Corp. launched its first product, the Amdahl 470 V6, in 1975, competing directly against IBM's high-end machines in the then-current System/370 family. (At IBM, Gene Amdahl had co-designed the groundbreaking 32-bit architecture, 24-bit addressing, System/360 line of computers. Applications written for the System/360 can still run, unmodified, on today's zSeries mainframes four decades later.) At the time of its introduction, the 470 V6 was less expensive but still faster than IBM's comparable offerings. For the next quarter century Am ...

Yonah was the code name for Intel's first generation of 65nm process mobile microprocessors, based on the Banias/Dothan Pentium M microarchitecture, incorporating LaGrande security technology. Floating point performance has been improved through the addition of SSE3 instructions and improvements to SSE and SSE2 implementations, while integer performance decreased slightly due to higher latency cache. Additionally, Yo ...

Windows Me - System Restore. Windows Me introduced the "System Restore" logging and reversion system, which was meant to simplify troubleshooting and solving problems. It was intended to work as a "safety net" so that if the installation of an application or a driver adversely affected the system, the user could undo the install and return the system to a previously-working state. It did this by monitoring changes to Windows system files and the registry (System Restore was not a backup program). System Restore c ...

Sun Microsystems - Operating systems. All Sun systems have been based on Unix systems which are well known for system stability and a consistent design philosophy. The Sun 1 was shipped with Unisoft V7 Unix. Later in 1982 Sun provided a customized 4.1BSD Unix called SunOS as an operating system for its workstations. In 1992, along with AT&T, it integrated BSD Unix and System V into Solaris, which as a result is based on System V Release 4. Sun offered a secure variant of Solaris called Trusted Solaris for releases before the current Solaris 10, which includes the sam ...

A change from a 32-bit to a 64-bit architecture is a fundamental alteration, as most operating systems must be extensively modified to take advantage of the new architecture. Other software must also be ported to use the new capabilities; older software is usually supported through either a hardware compatibility mode (in which the new processors support an older 32-bit instruction set as well as the new modes), through software emulation, or by the actual implementation of a 32-bit processor core within the 64-bit processor die (as w ...

The first VAX model sold was the VAX-11/780, which became available in 1978. The architect of this model was Bill Strecker. Many different models with different prices, performance levels, and capacities were subsequently created. VAX superminis were very popular in the early 1980s. In 2001 there were still VAX computers doing useful work, and Compaq was reportedly manufacturing and selling a tiny number of new ones. By 2005 all manufacturing of VAX computers had ceased, but old syst ...

Unlike languages like Fortran 77, C is free-form, allowing programmers to use arbitrary whitespace (rather than rigid lines) in laying out their code. Comments can be included either between the delimiters /* and */, or (in C99) following // until the end of the line. Each source file contains declarations and function definitions. Function definitions, in turn, contain declarations and statements. Declarations either define new types using keywords such as struct, union ...

Aside from its built-in features and different form factor, there were several other subtle differences between the SX-64 and the regular C64. The default screen color was changed to blue text on a white background for improved readability on the smaller screen. This sometimes caused compatibility problems with programs that assumed the C64's default blue background. The default device for load and save operations was changed to the floppy drive. In addition, the cassette port and RF port were omitted from the SX-64 because it had a built-in ...

Visual Basic is a controversial language; many programmers have strong feelings regarding the quality of Visual Basic and its ability to compete with newer languages like Python. It was designed to be a simple language. In the interest of convenience and rapid development, some features like compile time type-checking and variable declaration are turned off by default. This leads to some programmers praising Visual Basic for how simple it is to use, but also can lead to frustration when programmers encounter problems that the features would have detected (e.g., a typo genera ...

System/360 - A family of computers. Unlike past practice, IBM created an entire line of computers (or CPUs) from small to large, low to high performance, all running the same command set (with two exceptions for specific markets). This feat allowed customers to use a lower cost model and then upgrade to larger systems as their needs grew — without the time and expense of rewriting software. Many models (e.g. the 360/30) even offered the option of microcode emulation of the customer's previous computer (e.g. the IBM 1401 or the IBM 1620) s ...

The Pentium Pro is a sixth-generation x86 architecture microprocessor (P6 core) by Intel originally intended to replace the original Pentium in a full range of applications, but later reduced to a more narrow role as a server and high-end desktop chip. The Pentium Pro was capable of both dual- and quad-processor configurations. It was introduced using an enormous rectangular Socket 8 form factor in November 1995. Intel has since discontinued ...

HyperTransport runs at 200-1400 MHz (compared to PCI at either 33 or 66 MHz). It is also a DDR or "Double pumped" bus, meaning it sends data on both the rising and falling edges of the 1400 MHz clock signal. This allows for a maximum data rate of 2800 MTransfers/s per pair. The frequency is auto-negotiated. HyperTransport supports an auto-negotiated bus widths, based on two 2-bit lines to 32-bit lines. The full-sized, full-speed 32-bit bus in each direction has a transfer rate of 22,400 MByte/s, making it much faster than existing sta ...

Even as the original NES/Famicom was at the height of its popularity, several companies were launching their own consoles.

Although the NES would continue to dominate the video game industry for years to come, Nintendo's hardware was beginning to show its age, and though Nintendo executives initially showed little interest in developing a new system, Sega and ...

The first nCUBE machines to be released were the nCUBE 10 of late 1985. These were based on a set of custom chips, including a 32-bit ALU and a 64-bit IEEE 754 FPU with 128kB of RAM combined onto a board known as a module. Each module delivered 2 MIPS, 500 kiloflops (32-bit single precision), or 300 kiloflops (64-bit double precision), and ran the Vertex operating system. The name referred to the machines ability to build an order-ten hypercube, supporting 1024 CPU's in a single machine. Some of the modules would be used ...
