Well, a  little while ago I was trying to put my internal drive into the case
of a broken external drive, for portable storage.  Didn't work, but at least a
little good came of it.

If you have a IIsi with an internal Conner 40mb hard drive, adding an activity
LED is pretty easy.  Lift the drive up a bit (you will have to 'unsnap' it from
the case on the right & left) so that you can see the entire front of the
drive.  There should be a set of pins, which will look like this head-on:

   .... .
.  .... .

As you can see, there is a rightmost pair of pins a bit separated from the
others.  This is the pair of pins you connect the LED to.  Just get some longish
wires, solder them to a LED, and obtain some means of connecting the other end
of the wires to the pins.  Voila!  An activity light.  The most difficult part
of this project is deciding where to put the LED when you are done.  You can
drill a hole in the case (extreme probably warrantee voiding!!).  You can also
pop out the power LED, and pop in the HD LED, but then you can't see the power
LED.  I ended up putting it to the left of my floppy slot.  My floppy drive has
been broken for a long time, so that was a good place to put the LED (would you
believe it's cheaper to buy a new external drive than to replace it with another
internal drive??)
