List Of Doom Source Ports
''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. Since the ''Doom'' engine's source code was released to the public in 1997, hundreds of fan-made ports to various hardware have been developed. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doom (1993 Video Game)
''Doom'' is a 1993 first-person shooter, first-person shooter game developed and published by id Software for MS-DOS. It is the first installment in the Doom (franchise), ''Doom'' franchise. The player player character, assumes the role of a space marine, later unofficially referred to as Doomguy, fighting through hordes of undead humans and invading demons. The game begins on the moons of Mars and finishes in hell, with the player traversing each level to find its exit or defeat its Final boss (video games), final boss. It is an early example of 3D computer graphics, 3D graphics in video games, and has enemies and objects as 2D images, a technique sometimes referred to as 2.5D graphics. ''Doom'' was the third major independent release by id Software, after ''Commander Keen'' (1990–1991) and ''Wolfenstein 3D'' (1992). In May 1992, id started developing a darker game focused on fighting demons with technology, using a new 3D game engine from the lead programmer, John Carmack. ...

Solaris (operating System)
Oracle Solaris is a proprietary software, proprietary Unix operating system offered by Oracle Corporation, Oracle for SPARC and x86-64 based workstations and server (computing), servers. Originally developed by Sun Microsystems as Solaris, it superseded the company's earlier SunOS in 1993 and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. After the Acquisition of Sun Microsystems by Oracle Corporation, Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris. Solaris was registered as compliant with the Single UNIX Specification until April 29, 2019. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris Open-source software, open-source project. Sun aimed to build a developer and user community with OpenSolaris; after the Oracle acquisition in 2010, the Open ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QEMU
The Quick Emulator (QEMU) is a free and open-source emulator that uses dynamic binary translation to emulate a computer's processor; that is, it translates the emulated binary codes to an equivalent binary format which is executed by the machine. It provides a variety of hardware and device models for the virtual machine, enabling it to run different guest operating systems. QEMU can be used with a Kernel-based Virtual Machine (KVM) to emulate hardware at near-native speeds. Additionally, it supports user-level processes, allowing applications compiled for one processor architecture to run on another. QEMU supports the emulation of x86, ARM, PowerPC, RISC-V, and other architectures. Licensing QEMU is free software developed by Fabrice Bellard. Different components of QEMU are licensed under the GNU General Public License (GPL), BSD license, GNU Lesser General Public License (LGPL), or other GPL-compatible licenses. Operating modes QEMU has multiple operating modes: ... [...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 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 bundling work ...

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 family, ARM architecture. They are used in nearly all of the company's devices including Mac (computer), Mac, iPhone, iPad, Apple TV, Apple Watch, AirPods, AirTag, HomePod, and Apple Vision Pro. The first Apple-designed system-on-a-chip was the Apple A4, which was introduced in 2010 with the IPad (1st generation), first-generation iPad and later used in the iPhone 4, fourth generation iPod Touch and second generation Apple TV. Apple announced its plan to Mac transition to Apple silicon, switch Mac computers from Intel processors to its own chips at Apple Worldwide Developers Conference#2020, WWDC 2020 on June 22, 2020, and began referring to its chips as Apple silicon. The first Macs with Apple silicon, built with the Apple M1 chip, were unveiled on November 10, 2020. The Mac lineup completed its transition to Apple chips in Jun ...

Mac Transition To Intel Processors
The Mac transition to Intel processors was the process of switching the central processing units (CPUs) of Apple's line of Mac and Xserve computers from PowerPC processors over to Intel's x86-64 processors. 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. The transition was the second time Apple had switched 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 originally outlined that the move would begin by June 2006, with completion slated by early 2008 – the transition had proceeded faster than anticipated. The first-generation Intel-based Macs were released in January 2006 with Mac OS X 10.4.4 Tiger. In August, Jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Power Macintosh
The Power Macintosh, later Power Mac, is a family of personal computers designed, manufactured, and sold by Apple Inc., Apple Computer, Inc as the core of the Mac (computer), Macintosh brand from March 1994 until August 2006. Described by ''Macworld'' as "the most important technical evolution of the Macintosh since the Macintosh II, 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 68040, 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 co ...
