With the 82072 on the sun4c, you eject the floppy by setting (er,
clearing) a bit in the aux I/O register.  The sun4m has no corresponding
bit and you eject the floppy by enabling the motor on drive 3 (!).

What happens on the clone with the 82077, given that (being a sun4c)
it has an eject bit in the aux I/O register?
