Here's a few more (some are not x86 but I thought you guys might still be ineterested) that I stole off a web page. Particullarly interesting is the last site with a *lot* of oddball stuff. Enjoy! The following is a list of free operating systems that are specifically made for, or will run on, "obsolete" computers. The OS name's are followed by the intended processor/system and the "mainstream" operating system it attempts to emulate. ELKS (Embeddable Linux Kernel Subset) http://www.linux.org.uk/Linux8086.html ELKS is still in development and is an attempt to port Linux to run on an 8088/8086 processor. Future plans include 68000 and possibly Z80 ports. Caldera OpenDOS http://www.caldera.com OpenDOS is a replacement for MS-DOS or PC-DOS on 80x86 processor based systems and includes the source code for the kernel. LUnix http://wwwcip.rus.uni-stuttgart.de/~etk10217/c64.html LUnix is a UNIX type clone for the C64/128. Future plans include support for TCP/IP amomg other things. Proolix http://www.infocom.kharkov.ua:80/~prool/proolix.htm Another UNIX clone for 8088/8086 processor based systems that is somewhat similar to MINIX. Minix http://www.cs.vu.nl/~ast/minix.html Here it is, the original 8088/8086 UNIX clone. This is the Operating System that gave rise to the popular Linux OS and is currently available for PC, Amiga, Macintosh, and Atari ST systems. UZI http://oak.oakland.edu/oak/cpm/uzi-pre.html Currently, there are no UZI "Home Pages" (atleast none that I know of). Here is a link for the FTP location of the UZI binaries for Z80 machines. OS/A65 http://www2.tu-chamnitz.de/~fachat/csa Originally made for a home built computer, OS/A65 was ported to the C64 and is theoretically portable to many other 6502 systems. Includes support for multitasking and TCP/IP. FreeDOS (DOS-C) http://sunsite.unc.edu/pub/micro/pc-stuff/freedos/freedos.html http://www.freedos.org FreeDOS is meant as a replacement for MS-DOS or PC-DOS for all 80x86 based systems. Other Operating Systems on the Net. http://www.cs.arizona.edu/people/bridges/oses.html This site has an exhaustive list of other free operating systems as well as a few links to other free operating systems pages.
