Nice work, Eric.  I like Earl - what/where is he from?

I need to get to work on an LCD project of my own, I bought a graphics LCD 128x256 at
All Electronics for a few bucks -$12?, I have all of the docs and they look like they
match the unit.  Wiring it will be a little weird, I need to just dive in and do it. 
I think I saw a 640x480 unit for less than $20 in the All Electronics catalog last
week.  Dunno if it's color, my unit is not.  

My strange way of doing this will be to get it working using an FPGA directly
interfacing with the LCD.  I can use PicoBlaze as a microcontroller.  Once I get it
working there, I should be able to fairly easily port it to the PIC board I bought for
it.  (I have fewer problems troubleshooting a Verilog design than I do a PIC design)...
