In this article "Legacy systems" means unsupported by manufacturer, whether it is a 80's home computers such as Commodore 64 or an operating system/series of operating systems no longer getting updates such as Microsoft's Windows 9x series of operating systems
The reason to discontinuing these products varies, in the case of home computers outdated hardware is normally the reason support ceases. For operating systems it varies from lack of profit/lack of commercial success (such as BeOS, OS/2) to devices it was designed for becoming outdated or failing themselves (such as BlackBerry OS).
- Before diving in;
- Note that many of these emulators are forks of other emulation projects, as such these versions may be marked as inactive while the main version is still active.
- If you have one of these systems (preferably on date-accurate hardware) please consider contributing to the this article by marking emulators with good speed and good compatibility as recommended.

BeOS
BeOS was a operating system developed by Be Inc., BeOS originally targeted the PowerPC platforms BeBox and Macintosh, and later 32-bit x86 computers.
- BeOS History
BeOS was developed by former Apple employee Jean-Louis Gassée, the first version of BeOS was released with the BeBox. In 1996 the CEO of Apple Inc., Gil Amelio started negotiations to buy Be Inc., the negotiations ended not working due to the Be Inc. CEO Jean-Louis Gassée wanting $300 million[1] with Apple offering $125 million , Apple instead purchased NeXT (Including NeXTSTEP) from Steve Jobs.

DOS
- For software that emulates DOS on other hardware, see x86 CPUs.
Born from the dawn of the digital age, DOS, reigned supreme through the 80s and early 90s. Though far from sleek, its unassuming might empowered millions to navigate the nascent world of personal computing.
With bare bones efficiency, DOS offered accessible power. Simple commands unlocked a plethora of tasks, from crafting documents to unleashing the magic of text-based adventures. For countless users, DOS wasn't just a tool; it was a canvas for exploration, a gateway to programming adventures and tinkering with the very fabric of digital logic.
While its limitations challenged and its error messages mocked, DOS fostered a generation of resourceful pioneers, adept at navigating command labyrinths and conjuring digital magic from lines of code. This era forged a unique bond between user and machine, where every keystroke held consequence and mastery felt truly earned.
Though DOS may grace museums now, its influence echoes in every modern operating system. Its legacy of simplicity and raw power reminds us that the most transformative innovations often arise from humble beginnings.
Windows 1.0x/2x/3x were graphical user interfaces (GUIs) built on top of MS-DOS. Those were the programs that runs a window manager on top of MS-DOS operating system. Many of the underlying device drivers and protocols had to be loaded in DOS for 3.11 to use them. On the other hand, Windows 9x (95, 98, ME) were standalone operating systems with DOS compatibility mode. Also NT3.x was an operating system as it included its own micro-kernel and device drivers [1].

MSX-DOS and MSX-BASIC
- For software that emulates MSX on other hardware, see MSX emulators.
The bustling landscape of 1980s home computing witnessed the emergence of the MSX platform, a standardized architecture for home computers. Beyond its versatile hardware, the MSX's success stemmed from its robust software environment, anchored by two key components: MSX-DOS and MSX-BASIC.
- MSX-DOS - A Tailored Disk Operating System
Derived from its namesake, MS-DOS, yet significantly streamlined for the MSX's limited memory footprint (64kB), MSX-DOS provided essential file management and disk access functionalities. Its compact design allowed efficient operation on early MSX machines, enabling users to store programs and data on floppy disks, expanding the platform's potential beyond mere game consoles. The intuitive command-line interface, akin to MS-DOS, fostered accessibility and a community of enthusiastic programmers comfortable navigating its text-based environment.
- MSX-BASIC - Bridging the Gap to Creativity
Built upon an extended version of Microsoft's Basic, MSX-BASIC served as the primary programming language for the MSX platform. Its accessible syntax and clear commands lowered the barrier to entry for coding, empowering users to unlock the creative potential of their machines. A rich library of built-in graphics and sound commands facilitated the development of games, animations, and even music, transforming MSX computers into versatile tools for artistic expression. The standardized nature of MSX-BASIC across different models encouraged collaboration and software sharing, fostering a vibrant community of users and programmers.

OS/2 (Operating System/2) is a series of Operating systems initially developed by IBM and Microsoft before their falling out.
- OS/2 history
- Joint development
IBM and Microsoft first signed the "Joint Development Agreement" in 1985, code named "CP/DOS". OS/2 1.0 was announced in April 1987 and released that december which only ran in Text mode, 1.1 released in 1988 and added the Presentation Manager (GUI) to OS/2, 1.2 added support to HPFS, 1.2 Extended Edition added TCP/IP and Ethernet support. in 1990 OS/2 1.3 release, the last version developed by IBM and Microsoft.
- Post-breakup develeopment
The deal to develop the Operating system together ended with Microsoft leaving development to IBM with Microsoft and IBM not agreeing on how to position OS/2 with Microsoft's Windows 3.0.[3]
Released in 1992 OS/2 2.0 was the first version of OS/2 with 32-bit support, in 1993 2.1 released, it boasted about it's compatibility with windows 3.0 (later windows 3.1). OS/2 3.0 labelled OS/2 Warp 3 released in 1994, Warp had more broad hardware support, better multimedia support, Internet-compatible netowrking, and included IBM Works, between Warp 3 and Warp 4 IBM developed the unreleased Workplace OS which only borrowed little sections of code from OS/2. OS/2 Warp 4 released in 1996 with java and speech recognition software.

- For software that emulates Windows 9x on other hardware, see Windows 95/98/ME emulators.
From 1995 to 2000, Windows 9x based operating systems painted the nascent digital landscape with vibrant hues and infectious possibilities. Though often temperamental, its intuitiveness and accessibility ushered in a new era of personal computing.
The iconic desktop metaphor and pre-installed games beckoned exploration, while dial-up connections hummed the soundtrack to global connectivity. Floppy disks, the currency of shareware treasures, fostered vibrant communities, united by troubleshooting forums and a shared language of shortcuts and error messages.
Windows 9x was a democratizing force, empowering users to create, connect, and play. Paint and Game Maker unleashed creativity, while Glide-based games ushered in a new era of 3D graphics for computers. Its limitations fostered ingenuity, and every mastered tweak felt like a personal conquest.
Though now as a legacy OS, Windows 9x's influence on interface design, user interaction, and accessibility remains. It was a learning platform, a social hub, and a canvas for digital dreams. A colorful pixelated playground that forever changed the trajectory of personal computing.
- Some emulators for MS-DOS are able to be used on a windows 9x system, only emulators for/with a version for windows 9x are listed below.
