You have a Universal Disk Controller.  Those two ribbon cables
connect disk drives.  One of the ribbons only carries one
drive.  The other ribbon can carry a drive chain (one drive
plugged into the back of another) of four drives.  The UDC card
supports 3.5" and 5.25" UniDisks, 400K Macintosh floppy drives,
800K Macintosh floppy drives, the Apple 3.5" drive (GS/Mac
compatible and daisy chainable), Laser 3.5" and 5.25" drives,
Smartport hard drives, and the Macintosh HD20 floppy port hard
disk.  The SuperDrive will function, but only at 800K.

Note: The programmer of the UDC firmware has posted that the
very last revision of the UDC firmware had the UniDisk 3.5
support taken out.  If you have a later card, you have to use
Apple 3.5 drives or SuperDrives for 3.5" access.
