There is an install guide here:
http://www.sequenti x.com/sq_ lcd.htm

Sorry, should have mentioned it on the list.
I have a stock of the white on blue displays, but don't yet have the adaptor
boards to fit them with a 16 way ribbon cable.
I should have them in a few weeks, the PCB suppliers are closed over
Christmas.

Best regards,
