Apple IIe Card - Manual (Page 33)

You can connect more than one Apple IIe disk drive to the Macintosh LC
by
daisy-chaining them. However, the drives must be connected in the
correct order for them to work properly:
■
If you have two Apple 5.25 Drives, connect the first drive to the
Y-shaped cable. Then connect the second drive to the first drive by
plugging the connector from the second drive into the port on the
back of the first drive.
