Do you mean the 5.24 drives?

An aquaintence of mine once used a UDC on his //e to control:
	a) 1 5.25 drive
and:
	b) 2 3.5 drives
           ^

I don't recall the arrangement of connections, but I would think that
at least the 2 3.5 drives where daisy chained.

(I *KNOW* that he *ONLY* had the one disk controller - the UDC)

BTW: the DuoDisk 5.25 does work the IIgs disk port (or at least it
did with the original ROM - I sold my DuoDisk before the 1st ROM
upgrade was announced - though I wouldn't be surprised if it no longer
works - with the original ROM (and system disk) I WAS able to connect my
IIgs to AppleTalk to use a LaserWriter - after the "upgrade," I had to
wait for Apple to release a loadable driver for AppleTalk.
