Hi, I want to construct my own expansion board with as many digital in's and outs as possible!! I know this can be done but I don't know where to start.

Dear Steve, Nobody wants to hear this said, and I hate to be the one to do it, but you can start by reading the data available on the Handy Board web site (quick duck to avoid thrown volt meter).
