Doom Source Ports
The present article is a list of known platforms to which ''Doom'' has been confirmed to be ported. ''Doom'' is one of the most widely ported video games. Since the original MS-DOS version, it has been released officially for a number of operating systems, video game consoles, handheld game consoles, and other devices. Some of the ports are replications of the DOS version, while others differ considerably, including modifications to the level designs, monsters and game engine, with some ports offering content not included in the original DOS version. Official ports Personal computers NeXTSTEP This was the version that the MS-DOS product emerged from, since, at the time, id Software was using a NeXTcube for its graphic-engine development. This version is sluggish on anything below an 040 NeXTstation/cube (though it runs smoother with a higher amount of memory), and is missing sound, which was added on the PC side. With NeXT-Step based on i486 architecture, it ran smoothly under al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doom (1993 Video Game)
''Doom'' (stylized as ''DOOM'') is a 1993 first-person shooter (FPS) game developed by id Software for MS-DOS. Players assume the role of a space marine, popularly known as Doomguy, fighting their way through hordes of invading demons from hell. Id began developing ''Doom'' after the release of their previous FPS, ''Wolfenstein 3D'' (1992)''.'' It emerged from a 3D game engine developed by John Carmack, who wanted to create a science fiction game inspired by ''Dungeons & Dragons'' and the films '' Evil Dead II'' and ''Aliens.'' The first episode, comprising nine levels, was distributed freely as shareware; the full game, with two further episodes, was sold via mail order. An updated version with an additional episode and more difficult levels, ''The Ultimate Doom'', was released in 1995 and sold at retail. ''Doom'' is one of the most significant games in video game history, frequently cited as one of the greatest games ever made. It sold an estimated 3.5 million copies by 19 ...

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 ...

End User License Agreement
An end-user license agreement or EULA () is a legal contract between a software supplier and a customer or end-user, generally made available to the customer via a retailer acting as an intermediary. A EULA specifies in detail the rights and restrictions which apply to the use of the software. Form contracts for digital services (such as terms of service and privacy policies) were traditionally presented on paper (see shrink-wrap agreement) but are now often presented digitally via browsewrap or clickwrap formats. As the user may not see the agreement until after they have already purchased or engaged with the software, these documents may be contracts of adhesion. Software companies often make special agreements with large businesses and government entitles that include support contracts and specially drafted warranties. Many EULAs assert extensive liability limitations. Most commonly, an EULA will attempt to hold harmless the software licensor in the event that the software cau ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

QEMU
QEMU is a free and open-source emulator (Quick EMUlator). It emulates the machine's processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems. It can interoperate with Kernel-based Virtual Machine (KVM) to run virtual machines at near-native speed. QEMU can also do emulation for user-level processes, allowing applications compiled for one architecture to run on another. Licensing QEMU was written by Fabrice Bellard and is free software, mainly licensed under the GNU General Public License (GPL for short). Various parts are released under the BSD license, GNU Lesser General Public License (LGPL) or other GPL-compatible licenses. Operating modes QEMU has multiple operating modes: ;User-mode emulation: In this mode QEMU runs single Linux or Darwin/macOS programs that were compiled for a different instruction set. System calls are thunked for endianness and for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SheepShaver
SheepShaver is an open-source PowerPC Apple Macintosh emulator originally designed for BeOS and Linux. The name is a play on ShapeShifter, a Macintosh II emulator for AmigaOS (made obsolete by Basilisk II). The ShapeShifter and SheepShaver projects were originally conceived and programmed by Christian Bauer. However, currently, the main developer behind SheepShaver is Gwenolé Beauchesne. History SheepShaver was originally commercial software when first released in 1998, but after the demise of Be Inc., the maker of BeOS, it became open source in 2002. It can be run on both PowerPC and x86 systems; however, it runs more slowly on an x86 system than on a PowerPC system, because of the translation between the PowerPC and Intel x86 instruction sets. SheepShaver has also been ported to Microsoft Windows. As a free software, a few variants exist to simplify the installation process on Intel-based Macs: * ‘Sheep Shaver Wrapper’ is built off of Sheep Shaver but it does some of the ...

Apple Silicon
Apple silicon is a series of system on a chip (SoC) and system in a package (SiP) processors designed by Apple Inc., mainly using the ARM architecture. It is the basis of most new Mac computers as well as iPhone, iPad, iPod Touch, Apple TV, and Apple Watch, and of products such as AirPods, HomePod, HomePod Mini, and AirTag. Apple announced its plan to switch Mac computers from Intel processors to Apple silicon at WWDC 2020 on June 22, 2020. The first Macs built with the Apple M1 processor were unveiled on November 10, 2020. In 2022, the newest Mac models were built with Apple silicon; only older models of the Mac Mini and the Mac Pro still use Intel Core and Xeon processors respectively. Apple fully controls the integration of Apple silicon chips with the company's hardware and software products. Johny Srouji is in charge of Apple's silicon design. Manufacturing of the chips is outsourced to semiconductor contract manufacturers such as Samsung and TSMC. A series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mac Transition To Intel Processors
Apple transitioned the CPUs of their Mac and Xserve computers from PowerPC to the x86 architecture from Intel. The change was announced at the 2005 Worldwide Developers Conference (WWDC) by then-Apple CEO Steve Jobs, who said Apple would gradually stop using PowerPC microprocessors supplied by Freescale (formerly Motorola) and IBM. This was the second time Apple changed the processor instruction set architecture of its personal computers. The first was in 1994, when Apple discarded the Mac's original Motorola 68000 series architecture in favor of the then-new PowerPC platform. Apple's initial press release said the move would begin by June 2006 and finish by the end of 2007, but it actually proceeded much more quickly. The first-generation Intel-based Macintoshes were released in January 2006 with Mac OS X 10.4.4 Tiger. In August, Jobs announced the last models to switch, with the Mac Pro available immediately and the Intel Xserve available by October (it actually shipped ...

Mac OS X Tiger
Mac OS X Tiger (version 10.4) is the 5th major release of macOS, Apple's desktop and server operating system for Mac computers. Tiger was released to the public on April 29, 2005 for US$129.95 as the successor to Mac OS X 10.3 Panther. Some of the new features included a fast searching system called Spotlight, a new version of the Safari web browser, Dashboard, a new 'Unified' theme, and improved support for 64-bit addressing on Power Mac G5s. Mac OS X 10.4 Tiger offered a number of features, such as fast file searching and improved graphics processing, that Microsoft had spent several years struggling to add to Windows with acceptable performance. Mac OS X 10.4 Tiger was included with all new Macs, and was also available as an upgrade for existing Mac OS X users, or users of supported pre-Mac OS X systems. The server edition, Mac OS X Server 10.4, was also available for some Macintosh product lines. Six weeks after its official release, Apple had delivered 2 million copies ...

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 ...
