Homebrew PCBs

A parallel display can take up too many pins for the application. 
Most serial display are much more expensive.

A good compromise is to use the PH Anderail serial driver kit for 
LCD's. These kits start at $5 and included a dedicated PIC acting as 
a serial to parallel LCD controller.

The PIC takes care of all the overhead and  has a built in command 
structure for display commands and works great!

These guys http://www.wulfden.org/k107/index.shtml  have just 
introduced a pcb to go along with PH Anderson's kit. It worth taking 
a look at.
