I have found a place that sold these and I got 12 of them.
I have spent the time interfacing them to the Adruino board and mapping out what it takes to drive them.
For some reason these are hard wired for 8 data only.(sorry no 4 pin input)
However they work well. To display text on all 16 locations is tricky as you have to tell it to jump to another DDRam location.
I will see about getting an image of the device very soon.
