Unscrew the two screws holding the circuit board to the bottom of the drive
and carefully lift it up.  Along one edge of the circuit board you will find
a place where it would appear that a resistor should be -- this place is marked
R7.  Solder a jumper into that spot to make this drive into an RD53.  Set the
drive select jumper to DS2 and you should be in business.

	Good luck,
	---Bob.

  On the swing-out logic board, there's an empty position labeled R7. Insert a
jumper there (you'll need a soldering iron).
