Hello
 I am a repair tech for medical equipment and am needing to make some
test boxes for simple location of the number of a wire that has been
cut off in a harnesses with as many as 256 wires in them.

These harnesses have a plug on one end and the cut-off unlabled wires
at the other end . Up untill now I have used what is called a "light
box" these boxes have a plug to plug the harness into.. 128 or 256leds
on them and an internal battery and a lead so that when you touch one
of the wires with the lead one of the leds will light showing which pin
on the plug is associated with that wire (each wire is then labled)

Now with what I would like to build.
Since you have to look at these wires through a microscope it is very
time consuming to look up from the scope to see the led every time.
What I would like to do is replace these leds with something that
announces the number like "21" "102" "128" etc. with a voice this
would make labeling much faster.
Does anyone know of a pre-made IC? or EEprom? that would have 128 or so
individual areas that could store the voice message for the number and
be random accessed. would it need some sort of special trigger? As im
sure you can tell my knowlege is limited in this area, I am just
starting to work on this project and anyones ideas would be greatly
appreciated.
