I managed to loosen the LCD from the front, it was glued but I won the battle!
Found a sticker saying "LINK wo12864-tgh#" and some searching gave me the following results:
Manufacturer of module : http://link-lcd.com/
Manufacturer of LCD with cog : http://www.newhavendisplay.com/specs/NHD-C12864WO-B1TGH-M.pdf
and this library would probably work: https://github.com/olikraus/u8glib
I've also made some progress probing the pinout of the main processor: robot.pdf (*Updated link, now works)
I also noticed that the IC I believed was a RTC module is probobly a 3.3v li ion charge module of some sort. Haven't found any data on it yet. It's marked with '327 35AR'
Next thing would be to do some programming.. :)
Please feel free to join my project!
