 You can't hook up a Disk II or 5.25" controller to a 3.5" disk drive..
 
 However, a 3.5" drive can be used in an Apple IIe (not sure about II, II+).
 There are two possible combinations:
 
 - Apple sold a drive called a UniDisk 3.5. This drive had a processor and
 buffer memory inside the case to allow it to buffer and effectively slow
 down the data transfer rate to the point where the Apple IIe could handle
 it. You still need to get a special controller card (often referred to as a
 "LIRON" card, because the word was silkscreened on the card).

There was also a controller card called the UDC made by Laser computer (IIRC)
that could run various combinations of 5.25 and 3.5 drives. Shouldve got one
back then.
