I got a display kit and driver board from http://www.moderndevice.com/products/20x4lcd-lcd117kit
The kit went together very quickly and easily. The only hard part was the manual talking about a 4 wire connection while the header pin and website talked about a 3 wire connection. It is just 3 wires.
One of the kits was missing a 5k mini pot, will have to see if radio shack carries one.
Now that I can read a keyboard and run a display, will a full scale portable computer be far behind? Next up is writing and reading from an sd card.

The link to the demo is in the description. I did modify it to use all 4x20 characters of the screen in the demo.
