No chip details though. I guess one interesting result could be re-documenting this chip. There are not so many pins to scan after you take out the known traces. Perhaps from there more information can be determined for programming and interfacing with this IC via other generations from the same house.

Any idea what the chinese instructions on the PCB bottom mean?
