Quoted from drummermike:New board eliminates the reset issue.
Only temporarily. http://www.kahr.us/daughterboard.html
"Resets happen on WPC pinball machines because the Driver Board's 5 volt power supply is minimally sized for the many functions it needs to drive. WPC series MPU Boards have a watchdog circuit that shuts down the board if the voltage on the 5 volt line drops below a cutoff voltage (around 4.7 volts)."
