That's what we did with the COMBOARDs (1981 - 1994) - they have a window
register near the CSR, through which you poke values into memory on the
board to load a board that had just been rebooted. I don't know
abouy the KXJ11, but the COMBOARDs also have a way for the host CPU
to restart the serial-card CPU.
