It could be getting hot trying to drive some signals while some other chip is 
driving it in the other direction.

You might poke around and see if you can find any signals that aren't at a 
clean high or low.

Or look for signals that are shorted to Gnd or Vcc.  Maybe add a few mA of 
load and see if they shift a bit.

My guess would be low, but what do you have to lose if you feel like trying 
something?
