A small windowing, microkernel (less than 64 kbytes long) operating system written in heavily bummed assembly language for MS-DOS computers. It multitasks rather nicely on a 6 Mhz Intel 80286 with at least 512K memory.

It was adapted to PDAs by adding pen recognition, which doesn't work very well.
