Hey everyone.
I'm looking to potentially read out program data from a consumer espresso machine to customise its functionality (safely with a low voltage power source!) It appears to have a 64 pin microprocessor with connections to a program port (which I'm hoping will be JTAG). Unfortunately the chip has no label. Similarly there is what looks like an 8-pin EEPROM with no label. Pictures here:

Front (program port):

Any clues on how to identify these parts? The pin numbering printed on the board and the program port mapping may narrow the possibilities, however I have little experience working with microprocessors in general. Happy to do the legwork if I'm pointed in the right direction. Cheers!
