do you know which lines are vcc, ground, and backlight?  if so you can
power it up and with a suitable resistor and volt meter see how easy it
is to pull the other lines high or low, this will tell you if they are
input or output.  once you know that you can play at sending it signals.


chances are some lines are data and one's a clock line, once you find
the clock line you can systematically try different values on the other
input lines and see what happens.  a logic pulser might also be nice,
but not essential.

note that there is of course some risk of frying the subject, but if you
have stacks of them and can't find any data frying a couple of them
isn't too expensive.  tracing the signals can help you find the
power/ground connections since they are shared, you can always probe
with an ohm meter to see which pins go more than one place, those pins
will be power.

you can probably assume 5v power.  not entirely trivial, but if you put
some time into it there's a fair chance you'll figure it out.  it's
hardest at first, as soon as you figure it out a little bit the rest
gets easy quick.
