EDGELOGIX RPI 1000 screen demo code not available

Hi all, i recently got my hands on an edgelogix RPI 1000 it looks like a very cool unit so far but the pdf user manual links to this link:


Which is a dead file :frowning:

from what i can deduce the unit uses SPI and spidev to talk to a ra8889 lcd controller but i am very unfamiliar with this chip and i cant find any examples or even documentation stating how to interface with it and control it, i can run the code on the pi which is compiled c called test_lcd and this just makes the screen go white and then does nothing, i just want to display analog and digital pin states on the screen so didnt think it would be a challange haha but im out of my depth! can anyone help point me in the right direction?
