Non connected pins should be connected to ground or Vcc.

If you download the PLD file it has the equations needed to make your own GAL chip, otherwise I can sell you an already made adapter with the programmed GAL for $20 shipped USPS priority. Just send me an email.

A picture of the what the adapter looks like is below.
