Implements basic functionality to write commands and data to the S6B0108 LCD display, and to read from it. Also implements a few high level functions for an 2x20 ascii display (S6A0069), basic input (cursor keys) and delay functions.

Observe that this is a work in progress, and it's not assured that code that runs on the emulator work on the hardware.

Build with make. The emulator runs under X11, so these are required libraries. I've used GCC 4.4.7 to compile these, on Debian and Red Hat distros.
