I can confirm this.  I have a later model AE FDHD and it works
as a 1.44MB drive with the SuperDrive controller.  Older model
AE FDHDs work as 1.6MB GCR drives connected to the IIgs built-in
port, but only as 800K drives when connected to the SuperDrive
controller.  The 1.6MB format requires the AE driver, which can
be found on ground.  The driver only works with older model
AE FDHDs.

Wrong, the UDC works with the Mac HD20.  I've seen one attached
to an Apple IIe.  There are two models of UDC cards.  One is the
older full size controller.  The second one is the newer, half
size card.  The IIe that was connected to the HD20 used the full
sized version.  I would think that the half sized card would
retain the capability.
