This is a Seiko 40x4 (or 4x40) character LCD screen. The model is M4024, and the full information stamped on it says "SII M4024 REV.J TW-22 94V-0" and it has "7JY" handwritten in black marker in a little box on it. Anyway I got it from mpja.com for about $35. It has a nice backlight, as you can see in the photos. It has two HD44780 controller chips on it, 16 pins (well, pinholes... I had to buy and solder the pins on myself... I bought a "26 (2 X 13) HEADER CONNECTOR", stock number 13266 PL at mpja.com, for $0.90), and 2 pins on the other end for the backlight's anode and cathode.
