Thix is an almost complete implementation of the POSIX.1 standard (IEEE Std 1003.1-1988). It is a UNIX-like kernel with many features real operating systems have: virtual memory, demand paging, protection, swapping, etc. The Thix Operating System is fully functional at this time, and many free software packages have been succesfully compiled/run under it, including development tools such as the GNU C/C++ Compiler suite. However, there is no networking support and the only drivers available are for floppy disks, (E)IDE hard disks, printers, virtual terminals, mem, kmem and null.
