Hi John,

I have programmed ones of these however, that was on a powerpc running 
inside an FPGA!  The principles remain the though.  Those displays 
basically have an 8-bit interface with an enable signal if I remember 
rightly, should be pretty simple to with communicate through a parallel 
port.  See http://www.xilinx.com/ultracontroller for example code on 
driving LCD screens.

Thanks
Mark
