ah, right - actually, that might be somewhat of a relief as my machine is 
a clone 4/60 and I was worrying that it might be different in some way..  

how can I find the specs of the 82077 controller?  (and, I guess the 82072 so
that I can see what will be different).  I'm prepared to fiddle around with
it for a bit..
