Some one published in Rainbow a how-to-modify the Controller for 4 physical 
drives.  You look it up,  but I did the mod ( a piggybacked I.C.)  and ran 
4 drives on the 3 machines  that I had running in the house.  My old Ribbs 
BBS machine sits beside me now with a case with 2 x 5.25 and 2 x 3.5 drives 
( & 2 hard drives).  That mod was was essential to run my systems in the 
pre hard drive days.  Patching the system was easy as I recall, but easiest 
with OS-9.
