Optrex DMC40457 LCD

I recently picked up a bunch of junk from a friend including 2 Optrex DMC40457 LCD's (and a bunch of what looks like telco circuitboards) I have never worked with LCD's before and I am looking for some ideas/ beginner guides for this model. The controller chip is a HD44780 if that helps.
