I have a couple of chips I'd like to identify. They are from an industrial motherboard by Sigmatek (Austrian company) from the mid-2000s.
First chip looks like it would be easy but somehow I haven't found anything yet. 44 pins; I feel I have seen that logo but can't identify it.
Next is something that looks like a custom IC by Sigmatek, made by Sharp. Am I hopeless here?
These two black chips with "P85" on them are reasonably close to the power supply section of the board:
Thank you!
