Winstar / Midas 100x16 OLED Display

I have this display.
As default it has 8 data pins but I believe by moving jumpers it can use 4 data pins or even SPI.
I would prefer to get display working in current state before modifying.
I cannot find a library for this display.
I have tried the Adafruit Character OLED library (yes, I know I have graphical display but I was hoping I might get something from it); so far I have blank display.
Has anyone used this display successfully and can they assist me?
Or can someone recommend a (simple) book or tutorial that will enable me to make sense of the data sheet and write my own library? My programming skills are pretty basic and I am unfamiliar with writing data to registers but am willing to learn.
