According to my spec doc for the Manta board, it says pin 2 was also
used as the disk change line on some drives. Pin four is typically head
load / front LED / eject, and pin 16 is motor control but at least one
drive uses that line for density change.

This is why I was getting confused as to what's typical for a 'normal'
drive (i.e. one set up for a PC)  :-)
