From the Sun hardware FAQ, 

                THERE IS SOME DISPUTE OVER WHICH SLOTS BELONG TO WHICH
                BANKS, or alternatively what order to fill them. The Sun
                Field Engineer Handbook for 12/15/93 says that the banks
                are in order as shown above but doesn't give a fill
                order. Other sources agree that banks are in order 0, 2,
                1, 3, and should be filled in numerical order, which is
                interestingly equivalent to a *fill* order of 0, 2, 1, 3
                with the banks in numerical order as shown -- and that
                was the fill order of near relatives (the SPARCstation 1
                and 1+).
