Hey Kyriakos / AVRFeakMan, did you ever have any luck driving that LCD? I have an old monochrome IBM PC LCD display that I'm curious about making a driver for. It has a bunch of the L7778a and L7900 modules on it.
That lcd_display.txt looks to have some very helpful info.
Anyone know where to find data sheets for the Toshiba L7778a and L7900 modules?
