Visopsys is a new operating system for PCs. It has been in development since late 1997. The kernel is small and fast, operates exclusively in 32-bit mode, and features real preemptive multi-tasking and virtual memory. The package includes a small suite of UNIX- and DOS-like commands, with which most users will be familiar, although Visopsys is not – and does not try to be – a clone of any existing OS. The binary distribution features an easy-to-use Java installation program, which works on Linux, Windows, and Solaris. You can install and demo the distribution on a floppy disk. Screenshot.
