Peter, that sounds exactly like a standard Hitachi HD44780 compatible
controller. This is a parallel interface using either 4 or 8 Bits. E is
an Enable signal, RW is Read/Write, and RS is Register Select. You need
to connect the wiper of a 10K pot to the Contrast line with the other two
connections to + and - (+5V and Ground).
