Our big 3B15 is configured as follows:
	IOA0
		ADLI0
		ADLI1
		ADLI2
	IOA1
		ADLI3
		ADLI4
		ADLI5
	IOA2
		ADLI6
		ADLI7
		ADLI8
	IOA3
		ADLI9
		ADLI10
There are also two tape drives, and 3 FSD's.

As far as I know,  the design limit is 4 ADLI'S to 1 IOA,  the practical
limit being 3 to 1.  The above config has been in operation for about one
year.

Our other two 3B15's are single cabinet machines.  Never got that one,  and
those boxes were upgraded just this past April.

A question for the net:  Has anyone recently upgraded to SVR3.1 on a 3B15?
What am I getting myself into?  We're looking to add the following to the
machine above:
	SVR3.1
	10BASE5: (Was 3BNET NI)
	WIN/3B V1.2
	3BFIM to connect to an ISN.
We'll probably remove one IOA community (24 ports)
Thank's
