- Georgos the DOS compatible operating system
- A free DOS-compatible operating system. Sample applications, discussion forum, and development information.
- 42
- PhysTechSoft Ltd.
- Makes PTS-DOS 2000: network support, file manager, archiver, internal boot virus protection, graphical web browser; email, telnet, FTP clients; many utilities, some for embedded system development.
- 43
- RMF-DOS
- Reduced Memory Footprint; goals: match functions of MS-DOS 6.22, IBM PC DOS 7.00, DR-DOS 7 subset. Written mainly in 2 free C compilers and assembler, most parts are smaller uncompressed than compressed parts of MS, IBM, DR. [Open Source, BSD]
- 46
- ZDOS
- Realtime, 32-bit replacement for 16-bit DOS, with modern features: multitasking, demand paging, SMP. Coded in pure Assembly language. Zebor Technology.
- 47
- Amateur OS: AMOS
- Scott Billingsley's OS: realtime for DSP and amateur radio, one user/application, 16-bit real mode, for i386+, FAT 12/16; no TSRs, library of routines to program into apps, minimal kernel support (minimize interrupts), written in NASM assembly and Sphnix C--.
- 48
- KOS
- Kid Operating System. Modular (run-time dynamic linking), preemptive multitasking, to have SVR4-like VM. Begun 1998 by young programmers, most of them students. Goal: not obtaining OS, but learning OS internals and functioning of x86 processors. Downloads, links, documentation. [Open Source, GPL]
- 50
- JNode
- Goals: all Java OS, flat memory model, for personal use, simple to use and install, any Java applications to run on it fast and safe. Descriptions, documents, screenshots, downloads. Open Source, LGPL.
- 51
- JOS: Java Operating System
- Collaborative undertaking by an international group of Java programmers and enthusiasts to create free Java OS. [Open Source]
- 53
- RCOSjava
- Tool designed to teach inner workings of operating systems: simple animated simulated OS and hardware coded in Java. RCOS successor.
- 54
- Sanos
- Minimal OS kernel for PC based server appliances. Lets you run java server applications without need to install host OS, only need normal Java HotSpot VM and Sanos. Description, documents, downloads, manifesto, links, contact. [Open Source, BSD]
- 57
- ShagOS
- Portable object-oriented microkernel OS, dynamically loaded device drivers, fully redesigned and rewritten many times in C++, runs on VAX, x86. Ongoing experiment in using O-O paradigm as framework for full OS, with distributed computing as main aspect in most design decisions.
