Hello Wil

You might want to check out the LCD Technical FAQ. It's at

ftp://ftp.armory.com/pub/user/rstevew/LCD/lcdfaq.zip

or

http://www.paranoia.com/~filipg/HTML/LINK/F_LCD_menu.html

Thanks to this FAQ i got a display connected to a 16C57 up and
running in very short time.

Amongst other things it describes the initialization for both
4-bit and 8-bit mode in detail.
