	Hi, Tony:

	In the Model 4 reference manual there are four pages that seem to be relevant:
...

#26-Model 4 I/O Bus,  #27-I/O Bus Timing Diagram, #28 &29- Model 4 Port Bits.

I can try scanning these and email them to you if you haven't dug up the
information elsewhere.

Sorry to post this to the list, but when I tried your email address it
bounced.
