Should not be any connection between a memory upgrade and cassette I/O. 
List all hardware changes made and, if any, software changes when 
installing the memory board.

Do you hear the cassette relay click? Does MOTORON cause anything to 
happen? Is the cassette "cable" plugged into the cassette correctly vs 
motor control and input/output?

Are there any other failures since the memory was installed? Any loose 
ICs? Voltage reference points on motherboard OK?
