Williams Pinball WPC/DCS FPGA Project - Dr. Edward CheungIn contrast, a wpc-DCS board with no ROMs installed, will have these lines as hi-Z, which is presumably the power-on state for this port. Clearly, there will be no sound issued by the DSP if it does not boot. This information will allow me to gauge if the DSP on the prototype is running or not.
