Jonathan,    (01)

You might consider contacting Doug and see how he's connected his 
keyset.  I seem to recall once his mentioning connecting it to the 
serial port, but he'd be able to confirm that.    (02)

It would be interesting to see if we can come up with a set of plans 
for constructing the keyset.  I wonder how hard it would be to 
reverse-engineer the one you have?    (03)
