I got some LCD's recently.  They have a sticker on the back - EPSON
EG2404y-AR.

There are 5 chips on the back on the PCB.  4 of them are Toshiba
T7778A's and one T7900.  They are graphic LCD's.  I've got a pinout for
the 14 pins but need to know how the data is to be formatted.  This is
my first time working with LCD's.  There are 4 data lines on pins
11-14.  Also, what voltages should be hooked up to it?

Thanks in advance.
