GEOS

A small windowing, microkernel (less than 64 kbytes long)

operating system written in heavily bummed assemblylanguage 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.
