I've been disassembling a CyberMaxx II with the hope of
reverse-engineering it to suggest the best way to use those famed TFT
LCDs that Halted is selling.

Unlike the video boards that Halted was selling for a short while, the
board in the CMII doesn't use a Matsushita driver IC (MN83803Ax) to
handle the final timing of the signals to the LCDs, but instead has a
68pin PLCC under a 2 x 1 inch heat sink.  

Unfortunately when I removed this heat sink, the IC markings were lifted
off as well.  All that I could make out was something like:
	CH220 1210

Does anyone know what this IC is, or could suggest some way of
identifying it??

thanks
