A new HC11 processor must be configured before it will work with the controller's normal firmware. To configure it, burn the correct configXX.bin file into an EPROM, install it in the controller, and power up the controller. If you have the controller's serial port connected to a computer or serial terminal, you should see a message indicating what value the config register was changed from and to. Remove the config EPROM and install the normal firmware. Reinitialize (if necessary) and everything should be ready to go.
