You can attach up to two floppy disk drives to the AIMB-740-B/741-B's

On one end of the cable is a 34-pin flat-cable connector. On the other end
are two sets of 34-pin flat-cable connector (usually used for 3.5" drives).
The set on the end (after the twist in the cable) connects to the A: floppy
drive. The set in the middle connects to the B: floppy drive.
