I have a few full length proto-boards but they do not have the interface circuitry ( just a jillion holes ). If you're using wire wrapped proto boards, JDR 800-538-5000 sells wirewrap cards with the layout for address decoder circuitry. If you buy the card without any decoder (which is what I do), they have a slim help manual, which shows a lot of nice interface schematics. If you're interested, email me your US mail address, and I'll send you a copy, or if you're in a hurry, I can fax the stuff.
