RealPC
RealPC was a Macintosh program that emulates an x86 PC, allowing the use of MS-DOS, Windows NT, Windows 95, and Windows 98. RealPC was compatible with PowerPC Macs running system software 7.1.2 through 9.2. Requirements were: Any Power Macintosh or Mac OS compatible, System 7.1.2 or later, Minimum 16 Mbytes of Ram, hard drive space for 50 Mbytes (MS-DOS), 60 Mbytes (Windows 3.x), 130 Mbytes (Windows 95), and any Macintosh compatible CD-ROM drive. RealPC emulated a Pentium-based PC with MMX technology, supported Sound Blaster and MMX, and allowed you to use a Macintosh joystick, allowing you to run PC programs, including MS-DOS, and Windows, games and applications, alongside your existing Macintosh applications. RealPC was provided with MS-DOS 6.22 already installed, so you could immediately run MS-DOS games and applications on your Macintosh. Linux was not supported and due to shared RAM between MAC-OS and RealPC Windows-98 was the reasonable limit. RealPC was able to convert V ...

SoftPC
SoftPC is a software emulator of x86 hardware. It was developed by Rod MacGregor, Henry Nash & Phil Bousfield, following the founding of Insignia Solutions in 1986 By MacGregor, with "about a dozen people who had left the CAD/CAM workstation specialist Computervision", believing in a market opportunity for an independent CAD/CAM consultancy. Originally a side project, SoftPC quickly became the main focus for the company, running PC software on workstations. Originally developed on SPARCstations, the first customer to license the software was Intergraph whose workstation had a proprietary processor architecture. Available originally on UNIX workstations to run MS-DOS, the software was ported to the Macintosh in 1987, and later gained the ability to run Microsoft Windows software. Besides Mac OS, supported platforms included SGI IRIX, Sun Solaris, HP-UX, IBM AIX, NeXTSTEP, Motorola 88000, OpenVMS on VAX and DEC Alpha systems, DEC ULTRIX, and others.

Macintosh
The Mac (known as Macintosh until 1999) is a family of personal computers designed and marketed by Apple Inc., Apple Inc. Macs are known for their ease of use and minimalist designs, and are popular among students, creative professionals, and software engineers. The current lineup includes the MacBook Air and MacBook Pro laptops, as well as the iMac, Mac Mini, Mac Studio and Mac Pro desktops. Macs run the macOS operating system. The Macintosh 128K, first Mac was released in 1984, and was advertised with the highly-acclaimed 1984 (advertisement), "1984" ad. After a period of initial success, the Mac languished in the 1990s, until co-founder Steve Jobs returned to Apple in 1997. Jobs oversaw the release of many successful products, unveiled the modern Mac OS X, completed the Mac transition to Intel processors, 2005-06 Intel transition, and brought features from the iPhone back to the Mac. During Tim Cook's tenure as CEO, the Mac underwent a period of neglect, but was later reinv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Machine
In computing, a virtual machine (VM) is the virtualization/emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination. Virtual machines differ and are organized by their function, shown here: * '' System virtual machines'' (also termed full virtualization VMs) provide a substitute for a real machine. They provide functionality needed to execute entire operating systems. A hypervisor uses native execution to share and manage hardware, allowing for multiple environments which are isolated from one another, yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, virtualization-specific hardware, primarily from the host CPUs. * Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU and video ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emulator
In computing, an emulator is Computer hardware, hardware or software that enables one computer system (called the ''host'') to behave like another computer system (called the ''guest''). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many Printer (computing), printers, for example, are designed to emulate Hewlett-Packard, HP LaserJet printers because so much software is written for HP printers. If a non-HP printer emulates an HP printer, any software written for a real HP printer will also run in the non-HP printer emulation and produce equivalent printing. Since at least the 1990s, many video game enthusiasts and hobbyists have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is interpreted by a current-era s ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows NT
Windows NT is a proprietary graphical operating system An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also in ... produced by Microsoft, the first version of which was released on July 27, 1993. It is a processor-independent, multiprocessing and multi-user operating system. The first version of Windows NT was Windows NT 3.1 and was produced for workstations and server computers. It was a commercially focused operating system intended to complement consumer versions of Microsoft Windows, Windows that were based on MS-DOS (including Windows 1.0 through Windows 3.1x). Gradually, the Windows NT family was expanded into Microsoft's general-purpose operating system product line for all personal computers, deprecating the Windows 9x family. "NT" was formerly expanded to "New Technology" but no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows 95
Windows 95 is a consumer-oriented operating system developed by Microsoft as part of its Windows 9x family of operating systems. The first operating system in the 9x family, it is the successor to Windows 3.1x, and was released to manufacturing on July 14, 1995, and generally to retail on August 24, 1995, almost three months after the release of Windows NT 3.51. Windows 95 merged Microsoft's formerly separate MS-DOS and Microsoft Windows products, and featured significant improvements over its predecessor, most notably in the graphical user interface (GUI) and in its simplified "plug-and-play" features. There were also major changes made to the core components of the operating system, such as moving from a mainly cooperatively multitasked 16-bit architecture to a 32-bit preemptive multitasking architecture, at least when running only 32-bit protected mode applications. Accompanied by an extensive marketing campaign, Windows 95 introduced numerous functions and features that w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows 98
Windows 98 is a consumer-oriented operating system developed by Microsoft as part of its Windows 9x family of Microsoft Windows operating systems. The second operating system in the 9x line, it is the successor to Windows 95, and was released to manufacturing on May 15, 1998, and generally to retail on June 25, 1998. Like its predecessor, it is a hybrid 16-bit and 32-bit monolithic product with the boot stage based on MS-DOS. Windows 98 is a web-integrated operating system that bears numerous similarities to its predecessor. Most of its improvements were cosmetic or designed to improve the user experience, but there were also a handful of features introduced to enhance system functionality and capabilities, including improved USB support and accessibility, as well as support for hardware advancements such as DVD players. Windows 98 was the first edition of Windows to adopt the Windows Driver Model, and introduced features that would become standard in future generations of Wind ...

Harold Lloyd
Harold Clayton Lloyd, Sr. (April 20, 1893 – March 8, 1971) was an American actor, comedian, and stunt performer who appeared in many silent comedy films.Obituary ''Variety'', March 10, 1971, page 55. One of the most influential film comedians of the silent film era, Lloyd made nearly 200 comedy films, both silent and "talkies", between 1914 and 1947. His bespectacled "Glass" character was a resourceful, ambitious go-getter who matched the zeitgeist of the 1920s-era United States. His films frequently contained "thrill sequences" of extended chase scenes and daredevil physical feats. Lloyd hanging from the hands of a clock high above the street (dangerous, but risk exaggerated by camera angles) in ''Safety Last!'' (1923) is considered one of the most enduring images in cinema. Lloyd performed lesser stunts himself, despite having injured himself in August 1919 while doing publicity pictures for the Roach studio. An accident with a bomb mistaken as a prop resulted in th ...
