The card supported both 5.25" and 3.5" drives.  It supported all
Macintosh floppy drives from SuperDrive (in 800k mode) to
400k "eject buttonless" models.  It supported Apple IIGS 3.5"
drives too.

You don't want to use UniDisk 3.5 with it.  That model is slow
and not needed with the UDC.  Early UDC cards supported the
UniDisk 3.5 too but later ones had support taken out since
everyone was using the UDC with IIGS or Laser (Mac 800k
compatible) 3.5" drives.

Put the card in slot 5 of an Apple IIe and connect some IIGS
3.5 drives and watch it go.  Either daisychain both off port 1
or put one on port 1 and one on port 2.  It does not matter.
Port 1 supports several, not just 2, drives daisychained but
it only supports daisychaining provided nothing's on port 2.
